Title: Hydraulic energy collecting system
Inventor: NARAHARA TOSHIHIKO
IPC: F03B17/00
Filed: 1980-12-10
Abstract: PURPOSE: To enable effective collection of high-pressure air without solution by compressing internal air through the depth-of-water hydraulic pressure of a hydraulic-pressure receiving pipe and by collecting the tight-pressure air in a main high-pressure air tank.  
     CONSTITUTION: By opening of ventilating water valve 9a, the water in a deep water sleeve 1 is lifted through a hydraulic pressure receiving pipe 7, a lower ventilating main water pipe 5, and a ventilating main water pipe 8, 8...8a. On the other hand, the water in the deep water sleeve 1 is reduced, so water is charged from a charging pipe 4 until the depth of water reaches H required. As a result, where internal air pressure becomes equal to atmospheric pressure P o , the air is compressed by the depth-of-water hydraulic pressure (P o +PH) of the hydraulic pressure receiving pipe 7 and high-pressure P is collected in a high- pressure tank 11, thus high-pressure air without pollution can be wllasted effectively.

Title: Device for preventing balancing of safe ball receiver for use in japanese pinball game @(3754/24)pachinko) machine
Inventor: MORI OTO
IPC: A63F7/02
Filed: 1992-06-09
Abstract: PURPOSE:To liminate the possibility of trouble occurring due to a ball jam and causes of play interruption by setting the balance of weight between a ball weight detecting piece and a lever such that, if shot balls have entered a rolling and fixed ball receiving piece simultaneously, the piece which has received either of the shot balls earlier is slightly heavier. CONSTITUTION:The ball weight detecting piece 21 of an integrally formed pipe 18 is retreated to form a deep ball receiving face 21a and the center of gravity of the weight detecting piece 21 is brought close to an axis 17 to lengthen a lever 19. Since the lever 19 and the ball weight detecting piece 21 have their centers of gravity brought close to the center of the axis 17, there is an instantaneous, minute time difference between a shot ball (a1) entering the ball receiving face 21a and a shot ball (a2) put on the long lever 19 and static balance of weight does not take place. If the shot ball (a1) has entered the face 21a earlier with a minute time difference, for example, it flows on the lever 19, rotates the integrally formed pipe 18 clockwise, makes the lever 19 almost vertical, goes out of a first outlet and goes deep into the ball receiving face 21a. If the shot ball (a1) has entered the face earlier, the shot ball (a2) rotates the integrally formed pipe 18 clockwise and escapes.

Title: Optical disk reproducing device
Inventor: NAKANO EIJI
IPC: G11B7/135
Filed: 1993-06-22
Abstract: PURPOSE:To enhance the accuracy and the stability of tracking control by correcting a tracking control means in obtaining continuously a regenerative signal during reproducing an optical disk. CONSTITUTION:An average value R1 of a data amt. per unit time to be read out by an optical head 1 and to be transmitted to a head amplifier 2 is made larger than an average value R2 of a data amt. per unit time to be transmitted from a buffer memory 3 to a demodulation circuit 4. Information read out by the head 1 is stored in the memory 3, and is demodulated to be a real time regenerative signal. Since the data amt. per unit time read out by the head 1 is larger than the data amt. to be used for the demodulation circuit 4 for the purpose of obtaining the real time regenerative signal, the feeding degree to the memory 3 is large during reading information. Then, upon arrival of the feeding degree at a prescribed value, the reading is stopped, and the correction of the tracking control means 5 is performed. Meanwhile, the accumulated data in the memory 3 are demodulated, and are not to be discontinuous. Upon completion of the correction, reading of, information is performed again. Thus, the correction of the means 5 is performed repeatedly during reproducing.
