Title: Power amplifier circuit
Inventor: KIDA MIKIO
IPC: H03F1/02
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To reduce the collector loss of a power transistor at the time of inputting a small voltage signal and to reduce distortion components, a heat generating quantity and power consumption at the time of inputting a large voltage signal by controlling the power source voltage of an impedance converting circuit based on an input signal to the impedance conversion circuit and an output signal from an error detection circuit. SOLUTION: In order to remove distortion component generated at the output signal, an error component is detected by the error detection circuit 6 from the input signal to the impedance conversion circuit 2 and the output circuit, the value of the error component is maintained by a peak holding circuit 14 and the value of an error component from a pulse width modulation circuit 7 is added to the output of a voltage amplifier circuit 1 as a bias voltage. The pulse width of a triangular wave signal from a signal generating circuit 16 is controlled by the added signal. Consequently, as the power source voltage of the circuit 2 is increased and reduced by following up the increase/reduction of the voltage of the input signal, the distortion component of the output signal is reduced.

Title: Device of judging center position of head to leg of screw material to be good or not
Inventor: UEDA TAKASHI
IPC: G01B3/42
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To judge the center of the head of a screw material to the leg to be dislocated or not simply by putting the leg into an insertion hole. SOLUTION: This device is fitted to a screw material 1 with the head 2 sized larger than the leg 8. An insertion hole 11 is bored with the maximum allowable size of the leg in an allowable range of diameter and a guide hole 12 which is almost concentric therewith and in the same shape as the seat of the head 2 of the screw material 1 is provided above the insertion hole 11 to form a judgment tool 10. Judgement whether the center position of the head 2 to the leg 8 is good or not is made by the existance of a difference between the head top 5 of the screw material 1 and the upper end face 15 of the judgement tool 10 when the leg 8 is inserted in the insertion hole 11 in the judgement tool 10.  At this time, as there is no need for an operator to turn the screw material with a plug gauge and watch its deflection, no personal misjudgement is caused by the operator and such judgement can simply by made by anybody. No special device to measure the deflection of the screw material is required and a time and labor for such measurement are saved.

Title: Optimal position determination device and method
Inventor: KAWAKAMI KAORI
IPC: H01L21/60
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To enable the optimal position of bonds to be determined by a method wherein an indication that indicates a change in an arrangement position to a position determining means is provided, when an evaluation result of an evaluating means indicates that it does not meet constraint conditions. SOLUTION: It is evaluated by a constraint sufficiency evaluation part 28, whether the tentative position of bonds determined by a single B tentative position determination part 25 as a first positioning means, and the tentative position of pads determined by a P tentative position determination part 27 as a second positioning means, meet wiring processing constraint conditions or not. The constraint sufficiency evaluation part 28 indicates to the single B tentative position determination part 25 or the P tentative position determination part 27 that a tentative position must be changed when wiring processing constraint conditions are not met. By this setup, an optimal position can be determined even when wiring processing constraint conditions are not met if the bonds are not changed in arrangement position.

Title: Pachinko game machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 1999-12-16
Abstract: PROBLEM TO BE SOLVED: To provide a pachinko game machine which avoids forming the finishing condition of a specific game state due to small unexpectedness and avoids disturbing the tension state of mind and the feeling of expectation concerning whether the specific game state continues or not. SOLUTION: The starting time of a V-effective period is set to be a time when a prescribed period passes after a special variable prize-winning ball device 9 is shifted to an opening state. Thus, unlike the constitution where the V-effective period is started from the time when the device 9 starts opening, it is possible to avoid forming the finishing condition of the specific game state due to small unexpectedness such that a ball is not shot well when the device 9 is opened and it is possible to avoid disturbing the tension state of mind and the feeling of expectation concerning whether the specific game state continues or not.

Title: Gas meter and method for detecting gas leak
Inventor: NISHINO MITSUSHIGE
IPC: G01F1/00
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To provide a gas meter and a gas leak detection method whereby gas leaks can be detected at early stages while gas leak detection errors can be prevented. SOLUTION: When a flow rate value 166 from a flow rate computing part 162 is less than the minimum flow rate of gas equipment, a leak determination control part 161 determines that there is the possibility of gas leaks after the elapse of a predetermined allowable leak time. When the flow rate value 166 exceeds the minimum flow rate of the gas equipment, individual flow rates are calculated and allowable service times corresponding to the individual flow rates acquired. If variations of the flow rate value 166 are within a predetermined range of flow rate variations over the allowable service times acquired, the leak determination control part 161 determines that there is the possibility of gas leaks. Even in the event of such abnormalities as trace gas leaks, determination as to whether gas is leaking can be made earlier without errors.

Title: Liquid chromatographic/mass spectrometer
Inventor: TANAKA YASUFUMI
IPC: G01N27/62
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To maintain the temperature of a heated capillary constant. SOLUTION: A current measuring section 14 detects the value of a high- voltage current Ih impressed upon a nozzle 12 at the front end of a needle 11 which separates charges from a solution. When the value of the current Ih is large, the quantity of liquid drops generated by atomization becomes larger and the heat capacity of a heated capillary 16 increases, because the quantity of charges given to the liquid drops per unit time becomes larger. Therefore, a control section 15 controls a heater driving section 19 by calculating the power supplied to a heater 17 after correcting the parameter of the heat capacity in accordance with the value of the current Ih. Consequently, the temperature stability of the capillary 16 is improved, because the heating power can be adjusted before the temperature fluctuation of the capillary 16 is actually detected.
