Title: Computing method for control voltage of motor
Inventor: MATSUURA YASUMASA
IPC: H02P29/00
Filed: 1989-07-18
Abstract: PURPOSE:To control a motor with excellent follow-up properties by computing the sum of a value obtained by multiplying the difference of target rotational speed and actual rotational speed by a first constant, a value, acquired by multiplying actual rotational speed by a second constant and specified offset voltage and obtaining control voltage. CONSTITUTION:The rotational pulses of a rotary encoder 12 are sent to an encoder-signal input section 13, and the detecting output of the encoder-signal input section 13 is transmitted over a control section 14. The control section 14 reads the contents of a capture register 134 and an up-down counter 136 at every fixed sampling time, acquires the number of revolution of a servo motor 10, and computes applied voltage from the difference of the actual number of revolution and the command number of revolution. Accordingly, the servo motor 10 can be controlled with excellent follow-up properties.

Title: Power source circuit
Inventor: ISHIMA KAZUMI
IPC: H02M7/21
Filed: 1981-11-19
Abstract: PURPOSE:To realize a power transformer and smoothing circuit which are reduced in size and lightweight by performing on-off control over a switching circuit by the output of a pulse width modulating circuit which imposes pulse width modulation by the detected voltage of a DC-side output voltage. CONSTITUTION:A supply voltage V1 from a commercial power source 1 is full- wave rectified by a rectifier 2 and voltage-divided by resistances R1 and R2. From the output voltage of a buffer amplifier 4, threshold voltages VTH1 and VTH2 of a window comparator 5 are derived. The comparator 5 outputs a signal with a logical level ''High'' when VTH1>=Vth>=VTH2 where Vth is the output of a buffer amplifier 3, or outputs a signal with a level ''Low'' as V3 when otherwise. A signal V3 is applied to the inhibition input terminal of a pulse width modulating circuit (PWM circuit) 6 to turn on a switching circuit 7 when the V3 has the level ''high'' or to turn off the circuit 7 when ''Low''. The PWM circuit is applied with the detection output voltage of a voltage detecting circuit 9 through a photocoupler 10.

Title: Oscillator with frequency divider
Inventor: YAMADA KUNIHIRO
IPC: H03K6/00
Filed: 1981-11-19
Abstract: PURPOSE:To attain frequency division with highly effective accuracy, by summing oscillation frequency deciding inputs at each clock input, counting an overflow signal and summing to the higher-order. CONSTITUTION:An accumulator 2 sums an input value for oscillation frequency decision and a value of a register 3 at each clock input and stores the result in the register 3 again. When the accumulator 2 is overflowed, a counter 4 counts it. The linking between the count result and the content of the register 3 is equivalent to the extension of the number of bits of registers and accumulators, and since the accumulation is shifted right with a shifter 5 for the division, the repetitive period with high accuracy can be obtained.

Filed: 1986-08-08
Abstract: PURPOSE:To aim at abatement in an exhaust noise, by forming an incline, going down toward an exhaust port, in the head of a piston, and installing a partial peripheral edge in this incline so as to cause it to come into a piston outer circumferential surface from a ridgeline to be formed between the piston outer circumferential surface and the head. CONSTITUTION:An incline 23 tilting toward an exhaust port 24A is formed in the head of the piston 19 installed in a cylinder inner wall 20 of a cylinder body 12 free of reciprocating slide motion. This incline 23 is formed in a flat form obliquely cutting one side of the spherical head forming a top part of the cylindrical piston 19, and the lower end peripheral edge is installed so as to be lower than a peripheral ridgeline of the piston 19 and to come into the outer circumferential surface inside.

Title: High-frequency pulse arc welding source
Inventor: KONO HITOSHI
IPC: B23K9/09
Filed: 1986-08-08
Abstract: PURPOSE:To obtain a welding current over current capacity of switching elements for generating a pulse current by connecting a primary winding of a transformer having the number of turns of a secondary winding less than that of the primary side with an output end of a pulse current generation part and besides, provided a bypass path allowing the welding current to flow back without passing through the secondary winding. CONSTITUTION:A controller 20 controls on/off of the switching elements 3 and 3, 4 and 4' and 24 based on the welding current Iw detected by a current detector 15. When the switching elements are turned on, the welding current Iw rises and next, when both the switching elements 3 and 4 are turned off, the exciting energy of the transformer 19 is regenerated by a DC power source 1 and a secondary current is rapidly decreased. When the switching element 24 is turned on in the course of the secondary current being decreased, the welding current flows back via a diode 18 and is decreased. Since the number of turns of the secondary side winding of the transformer 19 is less than that of the primary side winding, the current to flow through the switching elements 3 and 4 (3' and 4') is made to a value less than the welding current Tw.

Title: Portable power supply with battery charger
Inventor: YAMAMOTO SHIGEO
IPC: H01L31/04
Filed: 1994-07-14
Abstract: PURPOSE:To increase the number of charging/discharging times of a secondary battery on the next stage by operating the primary of a battery charger with a voltage as low as possible and increasing the secondary voltage slightly higher than the voltage of a secondary battery before feeding power to the secondary battery on the next stage. CONSTITUTION:The secondary voltage for quick charging is temporarily lowered by means of a reverse flow prevention diode 2, a quick charging secondary battery 3 connected in parallel with the cell 1 in order to store the charges received therefrom, and a DC-DC converter 4. The DC output then passes through a chopper to produce pulsating power which is boosted and smoothed to obtain a voltage higher than that of a secondary battery on the next stage thus feeding power, as required, to the secondary battery through a voltage converter 5. The operating time of an electric double layer battery as long as that of a general battery is ensured by lowering the output voltage of the electric double layer battery as low as 1V, for example. The voltage is fed through a chopper and boosted again in order to charge a secondary battery on the following stage thus realizing a perpetual operation through the secondary battery.

Abstract: PURPOSE:To transport passengers to an objective floor smoothly in an elevator, in which the incorrect operation is prevented by confirming the destination floor with voice when a destination floor registration button is pushed, by registering the destination floor when the response operation is not performed within a fixed time after the voice confirmation. CONSTITUTION:When a passenger gets into a cage (S1) and pushes a destination floor registration button of an operation board inside of the cage (S2), the destination floor is announced with voice from a speaker inside of the cage, and the voice guide, that urges the push of the same button again within a fixed time when the wrong destination floor button is pushed, is announced (S3). When the passenger listens this voice guide and notices, for example, that he pushed the button of the floor before the objective floor by one floor, he pushes the same button again within a fixed time (S4), and the registration of the wrong destination floor is thereby cancelled (S5), and the passenger pushes the right destination floor registration button newly. After the voice guide, when a fixed time is passed (S6), the destination floor is registered (S7), and the passenger is transported to the objective floor.
