IPC: H02P6/20
Filed: 1988-02-29
Abstract: PURPOSE:To simplify a circuit and avoid noise, by controlling starting current by controlling the gate voltage of a field-effect transistor. CONSTITUTION:A controlling circuit and a driving circuit are composed of Hall sensors HIC1-3 for detecting the position of a rotor, resistance arrays RA1-3, inverters Q1-3, an AND circuit O9, a driving coil 21 and its FET.TR 1-3, a controlling FET.TR4, an integrated circuit IC2 for obtain. ing index signal, an integrated circuit IC3 for generating the output of control signal, an integrated circuit IC4 for controlling rotational frequency, a three-terminal regulator IC5, and the like. At the time of starting a motor, pulse output from the sensor HIC does not come to a rating, and so the output of the integrated circuit IC4 is turned into the Zener voltage of a constant-voltage diode ZD1. By selecting the voltage properly, the drain current ID of the FET.TR4 can be kept to come to a constant value or less.

Title: Flow control valve device
Inventor: FUJISHIMA TAKASHI
IPC: B05B1/30
Filed: 1979-04-17
Abstract: PURPOSE: To supply liquid from two nozzles at a desired flow ratio and make the control of the flow rates of the nozzles easy by metering the liquid with a single metering discharge device and discharging the same from the two nozzles at the specified flow rates.  
     CONSTITUTION: When liquid is force-fed from a pressure liquid feed port 41, it fills upper and lower piston chambers 51, 52. Next, when pressure air is fed from a pressure air feed port 62, the lower piston chamber 52 communicates with the liquid feed port 3 and the liquid flows from the liquid feed port 3 into branch pipes 5, 6. At this time, the volume decrease of the lower piston chamber 52 owing to the movement of a piston 40 carresponds to the discharge rate of the liquid. The discharge rate of the liquid is controlled by the advance and retreat of a control barrel 58. The liquid discharged by the operation of the piston 40 is flowed into the channels 10, 11 of the branch pipes 5, 6 from the fluid channel 9 of a connecting pipe 4 and is discharged from the discharge holes 32, 33 of the nozzles 14, 15 at the previously specified flow ratio having been specified by the spacing between needle valves 20, 21 and valve seats 36, 37.

Title: Installation type ashtray
Inventor: NAKAMURA YUTAKA
IPC: A24F19/00
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To satisfy both of smokers and nonsmokers by adding a static form of not receiving ashes in a natural state. SOLUTION: An ashtray main body 1 is posture-changed by a posture change means 3 and turned to an ash non-receiving position side. At this time, accumulated ashes are cleaned. The ashtray main body 1 at the non-receiving position is locked by a locking means 4 and is not in a loose state. Thus, the form of not receiving the ashes in the natural state is realized and specifications for the nonsmoker are attained. In a nonsmoking area, even the smoker who sees the ashtray main body 1 locked at the non-receiving position feels hesitant about smoking by even daring to change the form incapable of receiving the ashes in the natural state. Thus, the smoking of bad manners neglecting no smoking is reduced.

Title: Air-fuel ratio control apparatus for on-vehicle internal-combustion engine
Inventor: NIWA TORU
IPC: F02D41/04
Filed: 1985-03-09
Abstract: PURPOSE:To prevent the deterioration of operability in the transient operation of an internal-combustion engine by making an air-fuel ratio lean in accordance with the values of operational parameters. CONSTITUTION:Information, such as a vehicle speed, an engine speed, and the like, is supplied to a CPU 29 in a control circuit 20. When the CPU 29 judges that a vehicle speed changing rate is below a given value and therefore an internal-combustion engine 5 is in a normal operational condition, the valve opening duty ratio of an electromagnetically operated valve 9 is calculated. The higher the shift position of a transmission is and the higher the vehicle speed is, the larger the valve opening duty ratio is. When the duty ratio is calculated, a valve opening specifying command is fed to a drive circuit 28 and the electromagnetically operated valve 9 is opened for a time in proportion to the duty ratio, supplying secondary air to the engine 5. Thus, an air-fuel ratio is made lean in a rate in accordance with the values of a plurality of operational parameters and the ratio is not made lean in a transient operational condition, preventing the fall of an engine power.

Abstract: PROBLEM TO BE SOLVED: To operate a hybrid vehicle which uses a heat engine such as an internal combustion engine together with an electric motor under the optimal operating conditions wherein torque and the number of revolutions are kept constant in order to prevent the deterioration of exhaust gas emission of the engine. SOLUTION: A hybrid vehicle has an internal combustion engine 1, a motor 2 which also serves as a generator, and a driving shaft 4 which transmits torque necessary for running a vehicle to wheels 61. In such a hybrid vehicle, the torque of the driving shaft 4 is distributed to an output shaft 11 of the engine 1 and an output shaft 21 of the motor 2. In order to change the torque distribution ratio, a variable speed planetary gear unit 3 which is a non-stage transmission is installed as a torque distributor between the shaft 4 and the shafts 11, 21. The torque distribution ratio and the number of revolutions of the output shaft 21 of the motor 2 are so controlled that the torque of the output shaft 11 and the number of revolutions of the engine 1 may be constant optimal values by adjusting the ratio of the number of revolutions of the shaft 11 to that of the shaft 21.
