Title: Video signal compressing device
Inventor: HATANO YOSHIKO
IPC: H04N11/02
Filed: 1990-06-13
Abstract: PURPOSE:To compress a video signal without damaging subjective picture quality by limiting bands different at every field against the video signal. CONSTITUTION:An input analog luminance signal Y and color difference signals R-Y and B-Y are quantized by A/D converters 1-3. The only picture data part of each field from among the output of the converters 1-3 is extracted in an effective area extracting circuit 9. Horizontal sampling frequency is converted in the luminance signal Y, the color difference signals R-Y/B-Y, and frequency conversion circuits 10, 13, 16 from the circuit 9. On the other hand, the signals Y, R-Y, and B-Y outputted from the circuit 9 are inputted to scanning line conversion circuits 11, 14, 17 to convert the number of scanning lines. Changeover switches 12, 15, 18 are outputted by switching the output of the circuits 10, 13, 16 and the output of the circuits 11, 14, 17 at every field. The signal outputted from the switches 12, 15, 18 are inputted to a high efficiency encoder 7, further data-compressed.

Title: Method for controlling operating state of thermal head
Inventor: KURIHARA HIROSHI
IPC: B41J2/355
Filed: 1986-07-03
Abstract: PURPOSE:To control the operating state of a thermal head, by a method wherein, serial data inputted as printing informations are divided in a preset ratio to form a control pulse train and the number of pulses contained in the control pulse train are integrated. CONSTITUTION:When a clock signal C is inputted to a counter circuit 62, the counter circuit 62 selects the different address of EP-ROM61 at each time when the clock signal C is inputted to output the dividing signal B corresponding to a printing ratio from EP-ROM61. Said dividing signal B and serial data D are inputted to a comparing circuit 63 and the serial data D is allowed to pass only during a time when a pulse is inputted from the dividing signal B. Therefore, a pulse train E for controlling a thermal head wherein the serial data D is divided by the printing ratio is outputted from the comparing circuit 63. The number of pulses contained in the pulse train E are counted by a counter circuit 71 and a display circuit 7 displays the integrated value of the number of pulses on a display device 72. As mentioned above, the serial data are divided and the number of pulses contained in the formed pulse train for controlling the thermal head are integrated and displayed to control the operating state of the thermal head.

Title: Margin mechanism of foot brake
Inventor: WATANABE SHIYOUEI
IPC: H01L27/08
Filed: 1983-08-29
Abstract: PURPOSE:To prevent a link machnism from hunting due to vibration developed by road surface by a structure wherein a brake pedal and a rod to push the piston of a master cylinder are connected each other with the link mechanism and a margin mechanism is interposed at the connecting part of the links of the link machanism. CONSTITUTION:A push rod 16 to push the piston 13 of a master cylinder 9 and a brake pedal 10 are connected each other with a connecting rod 11. The connecting part is composed of a free movement mechanism consisting in piercing a pin 19 provided on the brake pedal 10 into an elongated hole 18 provided on the con necting rod 11. Accordingly, when a vehicle vibrates due to the unevenness of road surface, the inertia mass of the connecting rod 11 due to said vibration is absorbed by said margin mechanism and a return spring 21 is loaded with only the inertia meas of the brake pedal 10. Consequently, the hunting of the link machism consisting of the push rod 16, the connecting rod 11 and the brake pedal 10 can be prevented from occurring without making the elastic force of the spring 21 especially stronger.

Title: Underwater machinery
Inventor: ARAOKA TOSHINOBU
IPC: H02K5/132
Filed: 1981-10-01
Abstract: PURPOSE:To stabilize the operation under water by adopting a construction to reduce the difference between inside and outside pressures given to a shaft-sealing part down to zero for preventing the flowing-in of the water from the outside and the flowing-out of the oil or the like from the inside. CONSTITUTION:An underwater stirring pump 1 thrown into water and placed at a fixed bottom of the water receives a fixed water pressure as a whole. For adjusting pressures in the first oil chamber 6 and the second oil chamber 10 in a motor chamber, diaphragm variable-capacity bodies 20a and 21a contained in pressure-governor tanks 20 and 21 with oil enclosed inside as pressure medium receive the pressure of the water from under openings 20c and 21c at lower ends of these tanks. This pressure of the water is transmitted via the variable-capacity bodies 20a and 21a. The inner pressure of the second oil chamber 2 is equalized with the pressure of the outside water. Pressure give to a shaft-sealing part 11 from inside and outside a main body are balanced. This construction ensures a perfect sealing, and consequently allows to prevent the flowing-in of the water at the shaft-sealing part 11 and the flowing-out of the oil inside.
