Title: Fast pll circuit
Inventor: NAGOYA YOSHINORI
IPC: H03L7/089
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To improve the switching speed and to optimize the jitter and spurious reduction by forming a loop filter so as to secure the closed loop transmission characteristic of a closed loop part that is approximately identical to the Gaussian characteristic. SOLUTION: A loop filter 2 connects the single input of a phase comparator 1 to its output in response to the input of a PLL circuit. Then a voltage control oscillator VCO 3 is connected to the output of the filter 2. The output of the VCO 3 is branched out in response to the output of the PLL circuit and connected to the other input of the comparator 1 via a divider 4. That is, the PLL circuit generally includes a closed loop part which contains a transmission line consisting of the comparator 1, the filter 2 and the VCO 3 and a feedback line consisting of the divider 4. In this case, the filter 2 is formed so as to secure the closed loop transmission characteristic of the closed part that is approximately identical to the Gaussian characteristic.

Inventor: FURUYA SADAO
IPC: H01M50/609
Filed: 1985-05-20
Abstract: PURPOSE:To make the electrolyte amount of each cell uniform by forming a vent in each partition of container in alignment, pouring electrolyte with the container slanting, then returning the container in the vertical position after completion of electrolyte pouring. CONSTITUTION:When electrolyte is poured in each cell 3, a container 1 is slanted so as to position a vent 5 upward, then electrolyte is poured in one cell 3. Then the electrolyte is poured to a specified amount, the upper height of the electrolyte exceeds the position of the vent, and each cell 3 is connected through each vent and the electrolyte amount of each cell is made uniform. The container 1 is returned in the vertical position. By pouring the electrolyte to only one cell, the electrolyte amount in each cell is made uniform and the pouring of electrolyte is simplified.

Title: Constant speed traveling device for vehicle
Inventor: HASHIZUME TAKENORI
IPC: F02D41/14
Filed: 1995-05-01
Abstract: PURPOSE: To realize the stable vehicle speed control by limiting the increase in the vehicle speed command value so that the difference from the actual vehicle speed does not exceed the prescribed value to prevent the generation of the under-shoot when the actual vehicle speed can not follow the increase of the vehicle speed command value associated by the acceleration command. CONSTITUTION: A vehicle speed command value updating means F increases the vehicle speed command value by the prescribed value while the acceleration command is given, while the deceleration command is given, the vehicle speed command value is reduced by the prescribed value, and the detected vehicle speed when the acceleration or deceleration command is completed is updated as the vehicle speed command value. A vehicle speed command value increase/decrease limiting means G permits the increase of the vehicle speed command value when the target engine torque is higher than the prescribed value while the acceleration command is given, and permits the vehicle speed command value when the target engine torque is lower than the prescribed value while the deceleration value is given only in the range that the difference from the actual vehicle speed does not exceed the prescribed value.  The excellent acceleration/deceleration performance is obtained, and no under shoot is generated.

Title: Automobile air-conditioning device
Inventor: TOKORO HIROYUKI
IPC: B60H1/00
Filed: 1988-05-02
Abstract: PURPOSE:To enhance the blow-off air temperature controllability and an air- mixing ability by providing a subdamper to an air-mix damper at an end remote from a shaft so that the subdamper is rotatable while being urged toward a cool air passage by a spring, and is superposed on the air mix damper upon maximum cooling. CONSTITUTION:Upon air-mix operation, a subdamper 8 stands upright on the surface of an air-mix damper 5 on the cool air passage 4 side under the force of a spring 9. Accordingly, the area of the cool air passage is decreased so as to balance the resistance of the cool air passage with the passage resistance of a heater core 2. Accordingly, it is possible to approach a blow-off temperature variation characteristic corresponding to the opening degree of the air-mix damper. Further, due to the provision of the subdamper 8, the stream in a chamber is agitated so as to enhance the mixing with cool air. Further, when the air-mix damper 5 fully closes a hot air passage 8 during maximum cooling, the subdamper 8 is superposed on the air-mix damper 5 in association with the operation of an actuating member 8a so as to minimize the resistance. Thus, it is possible to enhance the air-mixing ability and the temperature control characteristic.

Title: Power amplifier
Inventor: KOKUBO KENICHI
IPC: H03F3/68
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To make a coil of a switching power supply small. SOLUTION: The amplifier uses a half wave signal whose output DC level is set close to a ground level to apply BTL drive to a load. A power supply voltage Vx for 1st and 2nd SEPP amplifier circuits 4, 5 is generated through a switching operation of a switching power supply circuit 12 in response to an output signal of an adder circuit 8 produced by adding output signals of the 1st and 2nd SEPP amplifier circuits 4, 5. Same input signals given to noninverting and inverting input terminals of a 1st differential amplifier circuit 1 are amplified by an amplifier circuit 14 of a clip detection circuit 13 and the resulting amplified signal is compared with a reference level at a comparator circuit 15.  When a level of an output signal of the amplifier circuit 14 is higher than the reference level, a stop signal in response to an output signal from the comparator circuit 15 is produced by a stop signal generating circuit 16 to turn on a transistor(TR) 17. Thus, an output signal from the adder circuit 8 is not fed to the switching power supply circuit 12, which stops the switching operation.

Filed: 1990-04-24
Abstract: PURPOSE:To operate a tablet without being disturbed by other operators by giving priority to one tablet and regarding other tablets not as an input object thereafter for a specific period. CONSTITUTION:An electronic pen 2 is put in an effective readable range 1a, namely, a tablet 1 which detects the electronic pen 2 is selected. Then the tablet 1 is given priority until the electronic pen 2 disappears from the range. In this case, the electronic pen 2 needs to be put in the effective readable range of the tablet 1 so as to obtain the priority of tablet operation. Other operators who lose this contention can not obtain the priority until the operator who wins the contention puts the electronic pen 2 out of the effective readable range 1a. Consequently, the operator can freely operate the tablet without being disturbed by other operators.
