Title: Delivery machine
IPC: A63F9/00
Filed: 1992-07-10
Abstract: PURPOSE:To permit the input for a variety of signals by installing the switches which can be operated by a shopboy but can not be operated by a player because of the constitution that a connecting member is interlocked with the operation of a lock part and the front surface of the switch is closed by the connecting member in locking, while the connecting member is shifted from the front surface of the switch, which can be operated in release. CONSTITUTION:Switches 157 are arranged so as to be operated from outside a medal lending-out machine through a sideway-long window 109 which is opened in the upper edge part of the front surface panel 80 of a medal delivery part 41. When a lock part 70 for medals is locking-operated, the horizontal long window 109 is closed by a locking member 92 for connecting the lower rods 75 and 76, while if the lock part 70 for medals is released, the connecting member 92 lowers, together with the lower rods 75 and 76, and the sideway-long window 109 is opened to operate the switches 157. Accordingly, a variety of signals can be inputted, and the mischief by a player can be prevented.

Title: Controlling device for induction generator
Inventor: KUDO TOSHIAKI
IPC: H02P9/00
Filed: 1992-07-13
Abstract: PURPOSE:To make the control of generated power possible without making an instruction wave height unduly small by controlling both of a current amplitude and a slip frequency by generating a signal of a predetermined pulse width at every timing of a commutation sync signal and providing a PWM enabling control section that uses this signal as a PWM disable signal. CONSTITUTION:A PWM enabling control circuit 15 generates a pulse signal that is in synchronism with commutation cycles, and supplies a PWM control circuit 14 with this pulse signal as a PWM enable signal EPWM. By making the 30 deg. latter half of a commutation cycle that corresponds to an electrical angle of 60 deg. a PWM disable period, a slip frequency is reduced from the case of not disabling the PWM. Therefore, even with the same instruction wave height, the generated power is reduced from the conventional cases to extend the control to a smaller power generation range. It is also possible to control generated electric energy by controlling the PWM disable period. With the ability to stably generate a small power even down to a zero power, the device is not only compact and inexpensive but also superior in performance.

Title: Fiber probe
Inventor: TOYOSHIMA NOBUAKI
IPC: G11B7/135
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a fiber probe with high reliability and high efficiency by decreasing resonance of light in the fiber probe to stabilize a recording and reproducing signal. SOLUTION: An aperture 73 smaller than the diameter of a core 71 is formed at the top end of a fiber probe consisting of the core 71 surrounded with a clad 72, and an antireflection film 75 is formed on the opposite end face to the top end. A metal coating 74 is applied around the aperture 73 to give a light-condensing effect by inner reflection. By forming the antireflection film, resonance of light caused in the fiber probe is decreased and an optical device using the fiber probe can be stably operated. Thus, the fiber probe with high reliability and high efficiency for introduction of light can be obtd. Or, instead of forming the antireflection film, the end face of the core opposite to the top end may be formed as inclined against the longitudinal direction of the fiber or formed into a curved face.

Title: Read overrun recovery system
Inventor: KUMAGAI KAZUO
IPC: G06F11/00
Filed: 1980-12-25
Abstract: PURPOSE:To reduce the occurrence of a read overrun by utilizing the skipping function of a channel device which can leave significant data bytes in a data storage memory as they are. CONSTITUTION:If the delay of the transfer of data byte due to the congestion of a system causes the delay of a reception answer signal to entail absence of a data byte, an overrun detecting circuit 20 detects an overrun to send a signal to a retry read storage circuit 19, which knows the start of retrying. During a retry read aftrr repositioning, the circuit 19 sends a signal, and consequently while an AND circuit 14 stops, an AND circuit 13 operates, so that a negative circuit 16 decreases the count value of a byte counter 18. On receiving the signal from the circuit 19, the counter 18 holds its contents in case of the occurrence of the overrun until the retry read after repositioning.

IPC: G11B15/44
Filed: 1984-09-04
Abstract: PURPOSE:To simplify a mechanism for the miniaturization of a motive power transmitter by using an idler which can move within a fixed range and making use of the power generated when the idler moves in the transmission mode of revolutions to the drive power of a tension control means which works when an operation mode is changed. CONSTITUTION:A drive wheel 8 keeps a revolving torque transmitted by a capstan motor 5 at a prescribed level. A rotary arm 23 is supported pivotally by boss part 16 of the upper drive wheel 13 of the wheel 8, and a rotary idler 24 is held freely rotatably at the tip part of the arm 23. Then the arm 24 revolves in the same direction as the wheel 8 and in allowed the rotary idler gear 24 to rotatably contact with an idler gear 32 at the take-up side and the idler gear 48 of the supply side respectively. Thus the revolutions of the arm 23 are transmitted to both reel drive disks 30 and 37 at the take-up and supply sides respectively. Then a rotary lever 53, a tension control means 34 and a tension band 38 work with engagement of a rotary idler gear 46 when a tape is driven toward B in a reproduction mode. Thus the brake torque added to the disk 37 is released. Thus the mechanism is simplified for the minaturization of a motive power transmitter.
