A piston pump in which a piston is moved reciprocatingly in a cylinder to make suction and exhaust strokes is used to supply a gas to the cylinder during the suction stroke of the piston pump and supply a high-viscosity material to the cylinder after the suction stroke individually batchwise. After the completion of the supply of the high-viscosity material, an exhaust stroke of the piston pump is effected, and, during the exhaust stroke, the gas and high-viscosity material are discharged to a conduit. The method comprises the first step of introducing a gas into a high-viscosity material, the second step of pressurizing the resultant mixed material by a pump, the third step of dispersing the mixed material by passing the same through a dispersion conduit, and the fourth step of foaming the mixed material by discharging the same. In the first step, piston pumps (45A, 45B) in which the pistons are reciprocatingly moved in cylinders to make suction and exhaust strokes, and a film separation type gas supply unit (10) for generating a gas by supplying compressed air thereto are used, and a low-pressure gas generated in the gas supply unit (10) is supplied to the piston pumps, whereby the gas is introduced into the high-viscosity material.

A device and method for receiving information and a device and method for transmitting information which can make TV audience surely view and listen to commercial programs. When a broadcast commercial program is displayed on a display (7A), the TV audience is requested to send responses. When the audience wants to respond to the request, the audience operates a prescribed one of the ten keys (32) of a remote controller (31). When the audience responds correspondingly to the response request of the commercial program, a point is added to a smart card (10). The audience can utilize the points recorded on the smart card (10) when the audience wants to view and listen to a pay-TV program.

A decoder for MPEG and the like, in which a voice can be outputted even if an image is frozen and the voice can be synchronized with the voice immediately after the image is unfrozen. A dynamic image data is frozen and outputted continuously by using the third output buffer region (8D) of a memory (8), and the I picture and P picture in a dynamic image data stream being inputted during freeze are decoded by using the first ouput buffer region (8B) and the second output buffer region (8C). A voice data stream is decoded while being kept in synchronism with the dynamic image. Since decoded I picture and P picture are stored in the first output buffer region (8B) and the second output buffer region (8C) even during freeze, the image data synchronized with the voice data can be outputted immediately after it is unfrozen.

An AT-cut crystal resonator comprising two exciting electrodes respectively formed on two main surfaces of an AT-cut quartz plate, wherein the relative positional relation between the two electrodes is shifted in the direction perpendicular to the X-axis of the quartz plate to such an extent that the frequency deviation of the resonator within a temperature range from -10 to 50 °C is reduced to be within a range of ± 2.5 ppm; and another AT-cut crystal resonator comprising electrodes faced oppositely to each other and disposed on both main surfaces of the quartz plate so as to be slightly shifted from each other in the opposite directions along the Z'-axis of the crystal, wherein a balancing load is formed on a piezoelectric substrate on the opposite side of the direction of shifting of the electrodes. Therefore, a crystal resonator having the oscillation frequency corresponding to various specifications can be provided at a low cost merely by performing such an easy and simple structural modification or change as slight changes in the arrangement or constitution of the electrodes without making such an endeavor as the elimination of the cut-angle deviation for enhancing the yield of nondefective quartz plates.

In an ADRC processing, an image is divided into blocks, and the maximum value MAX and the minimum value MIN of the pixel values of each block are detected and the local dynamic range of each block is determined by the equation DR=MAX-MIN. The minimum value MIN is subtracted from the pixel values of each block, and the remainders are divided by DR/2K to obtain the result of the ADRC processing. The result is used as an object of various editing procedures which may be substantially identical with those when the original image, not subjected to the ADRC processing, is directly edited. The edition load can be reduced as compared with the edition of the original image, because the amount of data of the ADRC processing result is small. Hence the image processing is performed efficiently.

 Appl.No PCT/JP1998/002183 Applicant YAMAHA HATSUDOKI KABUSHIKI KAISHA Inventor OGATA, Hiroaki
A wheel chair (1) with an auxiliary power which comprises an electric motor (32), a potentiometer (27) as a means for detecting human power exerted on a wheel (2), and a controller (31) as a means for controlling the electric motor (32) in accordance with the detected human power, and in which an auxiliary power corresponding to a magnitude of the human power is exerted on the wheel (2) to rotatingly drive it, wherein a time attenuation factor of the auxiliary power is preset to be inversely proportional to the human power. Since a coasting amount of the chair (1) is limited to be smaller than, for example, feeble movements in a room, it is possible for the chair to ensure small movements with a sharp turn in the room and an adequate coasting in outdoor travelling to enable comfortable travelling on a flat ground and easy climbing of a steeply sloping road with reduced occupant's physical load.

In an image processing device (10D) for processing image data constituting a dynamic image, pixels of every frame forming the dynamic image are thinned out removing pixels by determining a 5-pixel lattice format in both the space direction and the time direction, thereby reducing the amount of information while maintaining the resolutions in the horizontal, vertical and oblique directions of the dynamic image.
