Patent JP-H04125709-A (JP)
Title: Stabilized power supply circuit
Inventor: OOTA TOMOICHIROU
IPC: G05F1/56
Filed: 1990-09-18
Abstract: PURPOSE:To stabilize the output voltage by feeding back the output current to a constant voltage control means in a power supply circuit provided with a reverse current element diode, an output current detecting element, a power control element, and the constant voltage control means. CONSTITUTION:When an output voltage V0 rises, the voltage divided by output voltage setting resistances R3 and R4 rises. An operational amplifier OP1 compares this divided voltage with a reference voltage; and when the output voltage rises, it absorbs the base current of a power control element transistor TR Q1 to reduce the output voltage. When the output voltage is reduced, the divided voltage is reduced to raise the output voltage. When the voltage drop of a resistance R2 which detects the output current is increased and the voltage between the base and the emitter of a constant current control element TR Q2 exceeds a prescribed value VBB at the time of the increase of a load current, the constant current control is performed. Thus, the change of the output voltage V0 due to the load variation is minimized.

Abstract: PURPOSE:To calculate the number of pitches of a crepe paper positively and easily by determining the surface configuration of said crepe paper on the basis of smoothed data which is the smoothed data of displacement to a reference value in a thicknesswise direction, and determining the roughness of said surface from the change in an inclining direction of a tangent line in said surface configuration. CONSTITUTION:A sensor 3 is provided with a light emitting unit 7 and a light receiving unit. The light emitting unit 7 emits laser to the surface of a crepe paper and the light receiving unit receives the reflected light. At this time, a reflecting angle theta from the light receiving position at every measuring point on the surface of the crepe paper is detected, so that the displacement in a thicknesswise direction is calculated from the change in the reflecting angle theta. While the surface of the crepe paper 1 is scanned by moving the sensor 3, the reflecting angle theta is sequentially measured. The displace ment to a reference distance in the thicknesswise direction on the surface of the paper is sequentially input to a computer 5 as electric signals. The data of displacement is smoothed to determine the surface configuration. By specifying the roughness of the surface from the change in an inclining direction of a tangent line in the surface configuration, the number of pitches of the crepe paper 1 can be easily and positively calculated.

Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To provide a PACHINKO machine of a type requiring no reward ball collection box, by discharging for the player a sheet recording the number of reward balls discharged, instead of accumulating such balls on the player side as discharged out of the machine. SOLUTION: The PACHINKO machine 10 discharges reward balls through the discharge port 42 upon the occurrence of just put-in. When the upper tray pipe 46 has been fully filled with the reward balls, the balls pass through the discharge port 48, then, are detected by the discharge sensor 50, and discharged out of the machine through the discharge port 54. A number of reward balls so detected by the discharge sensor 50 is then shown on the display panel of the reward ball counter 22. Pressing the settling switch 32 activates the printer in the reward ball counter 22 to print out a number of reward balls on a sheet that is then discharged out of the machine through the record sheet discharge port 28. The players present this sheet to the shop to exchange it with the reward goods.  Since the reward balls themselves are not exchanged with the reward goods, the reward ball collection boxes become unneeded.

Title: Discharge lamp lighting device
Inventor: NAKAYA FUMINORI
IPC: H05B41/42
Filed: 1987-09-30
Abstract: PURPOSE:To dispense with a large switching element and realize stepped light adjustment with simple constitution by providing a changing-over circuit which changes over a rectification method between full wave rectification and double voltage rectification in a rectification smoothing circuit and changing over the output of a lighting circuit by this rectification method. CONSTITUTION:The AC input of a power source A is rectified at a diode bridge in a rectification smoothing circuit F and smoothed at condensers C1, C2 and input into a lighting circuit B. Then, if a change-over circuit S is closed, the AC input of the power source A is rectified into double voltage, and voltage 2E double the power source voltage E is input into the lighting circuit B, and the output voltage of the lighting circuit B becomes full lighting voltage and a lamp La lights fully. On the otherhand, if the change-over circuit S is opened, the AC input of the power source A changes from double voltage rectification over to full wave rectification and the voltage E of the power source A becomes the input voltage of the lighting circuit B and the lamp La is changed over to lighting at step-adjusted light. Hereby, a switching element having large capacity becomes needless and step light adjustment becomes possible with simple constitution.

IPC: B60Q1/40
Filed: 1985-11-06
Abstract: PURPOSE:To facilitate incorporation of a direction indicator by providing a separate structure of a control unit having an electric drive mechanism for returning a direction indicating lever from an operated position to a neutral position and electrically connecting the mechanism to a cancelling switch device operatively associated with the steering shaft. CONSTITUTION:When a control lever 6 at a neutral position is pushed, for example, upwardly, a pin 19 presses down an actuating rod 20k, so that lines of a switch device 20 between terminals 20c and 20d and between terminals 20g and 20h are closed, and a left-turn signal is outputted through a line 30L. When the vehicle has turned to the left and the steering wheel is returned, an interlocking plate 24 operatively associated with the steering shaft is rotated in the clockwise direction to cause a cancel pin 25L to move forward to push a switch lever 29 around. This results in closing of switch elements 27a, 27b to activate a solenoid 23, so that the control lever 6 is returned to the neutral position through an actuating rod 23a and a swing lever 21. This return causes the lines between the terminals 20c and 20d and between the terminals 20g and 20h to be opened.

Abstract: PURPOSE: To prevent delamination of an underlying Ti based adhesion layer, at the time of depositing a blanket tungsten, by growing Si nuclei at least in the region to be covered by a second jig on the surface between a substrate and the Ti based adhesion layer after finishing a first step before starting a second step. CONSTITUTION: A titanium based adhesion layer 5 is formed on a substrate 100 while covering at least a part of the peripheral edge part by means of a first jig 10 (first step).
