Title: Fuel modifying system
Inventor: AMAMIYA TAKASHI
IPC: H01M8/06
Filed: 1989-08-03
Abstract: PURPOSE:To minimize a difference in pressure between the inside and outside of a modifying tube which is in operation even during a period of transitional variation by providing the modifying tube with an inside/outside differential pressure detector and adjusting the opening of flow control valves in compliance with signals from the detector. CONSTITUTION:In a fuel modifying system in which a mixture of raw material fuel such as hydrocarbon and methanol and steam is introduced into the inside of a modifying tube 2 so that it is brought into contact with a catalyst, while combustion gas obtained by combustion of a mixture of exhaust gas from a fuel cell and air in a combustion chamber 3 is allowed to pass along the outer surface of the modifying tube, thereby modifying the raw material fuel into a hydrogen-rich modified gas, the 1st flow control valve 20 branching off from a combustion exhaust gas line 13 and the 2nd flow control valve 21 branching off from a modified gas line 12 are provided. When the inside/outside differential pressure of the modifying tube 2 exceeds a reference value, the 1st valve 20 is opened so that combustion exhaust gas is released to allow the pressure on the side of combustion exhaust gas to lower. When the differential pressure exceeds another reference value, the 2nd valve 21 is opened to allow the inside pressure of the modifying tube 2 to lower.

Title: Medium driving system for optical recording/reproducing device
Inventor: INOUE HIROSHI
IPC: G11B19/00
Filed: 1987-08-11
Abstract: PURPOSE:To remove the restriction of a recording area due to the variation of the starting position of a card end by performing constant speed control in a range where a light beam scans an information recording part, and changing it into position control in the track stopping/reversing part of a recording medium. CONSTITUTION:While recording or reproducing is performed as a card A being in a constant speed state, an MPU 10 instructs a polarity conversion circuit 11 so that the time constant of a frequency/voltage converter 3 and the gain of an amplifier 4 come to be prescribed values. At that time, a switch SW1 is being turned on and a driver 12 is operated by the loop of the constant speed control. Next, when information is outputted to the MPU 10, the MPU 10 turns on the switch SW4, and turns off the switch SW1, and changes the control into a position servo. Then, the recording area can be expanded by setting previously the terminal point of a track at high precision by the control by the position servo.

Abstract: PROBLEM TO BE SOLVED: To simply perform voice conversion with high quality without being affected by noise by changing the phase of a complex signal so that the angular velocity of the inputted complex signal is increased/decreased by a prescribed magnification. SOLUTION: This sound signal conversion device consists of a complex signal conversion part 10 and a phase variable adjustment part 20. Then, the complex signal conversion part 10 inputs a sound signal, and converts the inputted sound signal into the complex signal consisting of a real number part and an imaginary number part. The phase variable adjustment part 20 inputs the complex signal obtained by the complex signal conversion part 10, and changes the phase of the inputted complex signal so that the angular velocity of the complex signal is increased/decreased by a prescribed first magnification. Thus, the voice pitch is changed while maintaining an original voice speed, to be applied for the conversion of a key of accompaniment in 'KARAOKE' (orchestration without lyrics), and a device unspecified in speaker for example.  Further, the device is used for a special effect sound adding function of an electronic instrument.

Title: Preventing device for clogging of powdered developer in transfer path
Inventor: ISHII YOUICHI
IPC: G03G21/10
Filed: 1981-12-14
Abstract: PURPOSE:To prevent clogging of a toner by a simple constitution without requiring a special driving source, by providing a bridge preventing member which has fixed one end into a vertical path, and has fitted a weight contacting with a screw in a horizontal path, to the other end. CONSTITUTION:When a screw 4 is rotated, a toner which has dropped naturally in a vertical path 1 is trasferred in the direction as indicated with an arrow B, is sent to a vertical path 5 from a horizontal path, drops naturally in the direction as indicated with an arrow C, and is supplied to a developing device. On the other hand, when the screw 4 is rotated, a weight 7 moves with a toner, and when it moves by some distance and becomes a state that a wire rod 6 has been stretched tight, the weight 7 goes back by its empty weight, and collides with the crest part or the root of the screw 4. By vibration due to a shock in case of this collision, a toner which has been in a bridging state in the vicinity of the lower opening of the vertical path of the upper part of the screw 4 crumbles, therefore, clogging of a toner is prevented.

Title: Motor control device for vehicle
Inventor: MATSUMOTO HIROYUKI
IPC: F02D9/02
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To prevent vibration of a motor and repeatition of normal and reverse rotation thereof by providing a control means outputting a holding signal to repel a pulling force from the outside in order to maintain a present value of the motor when the present value reaches a target value. SOLUTION: At first, the number of engine revolutions, throttle opening degree and the like are detected, and then a target value and target zone values are computed by a target value computing means 14. Secondly, a present value of a motor 5 is detected by a potentiometer 1 serving as a present value detecting means, and the present value is compared with the value of target zone. In the case where a control mode is a drive mode when the present value is within a target zone, the renewal to a brake mode is made and a stop signal is output to a driver mode 13. In the case where the brake mode is completed when the present value is within the target zone, a holding mode succeeds, and with a minute current generating at that time the reverse rotation of the motor 5 is prevented.  Accordingly, the normal and reverse operation caused by delicate intermittent operation or hunting does not occurs, thereby improving the control accuracy.

Title: Pachinko machine
Inventor: ICHIHARA TAKAAKI
IPC: A63F7/02
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To give expectation of winning a prize by diversifying the movement of game balls and increasing the chances of the game balls to prize-win or pass through a specific area. SOLUTION: At a pachinko machine, rubber 42 is supported by a supporter under a gate 46. The rubber 43 is supported in an oblique direction with respect to the dropping direction of the game machine. Game balls passing through the gate 46 drop as they are and hit the rubber 4 to bounce. This rubber 42 converts the dropping energy of the game balls to elevating energy by elasticity to give the game balls. In addition as the rubber 42 is supported in an oblique direction by the supporter the moving direction of the elevating game balls is oriented toward first kind starting port 24. Thereby the possibility of the game machine to prize-win to the port 24 is elevated. This mode is similar at a rubber 22 supported at the lower side of a gate 18. Consequently, the movement of a player is diversified to give expectation of winning a prize to the player.
