Title: Second harmonic wave generating element and second harmonic wave generator and its production
Inventor: MATSUDA KAORU
IPC: G02B5/30
Filed: 1992-12-24
Abstract: PURPOSE:To generate second harmonic waves which are stable in output and low in noise by inclining either or both of the incident and exit end faces of the second harmonic wave generating element of a waveguide type with the optical axis of a semiconductor laser. CONSTITUTION:The waveguide 1 which is the second harmonic wave generating element and the semiconductor laser 3 which is an oscillation source for a fundamental wave are arranged in such a manner that the fundamental wave is made incident diagonally on the waveguide 1 by inclining the optical axis of the waveguide 1 having the incident end face perpendicularly to the waveguide 1 with the optical axis 6 of the semiconductor laser 3 in order to prevent the reflected return light from the incident end of the second harmonic wave generating element of the waveguide type. The reflected return light of the fundamental wave from the far end face 9 of the waveguide is prohibited by attenuating the fundamental wave when, for example, direct coupling is executed. Namely, the semiconductor laser 3 and the dielectric waveguide 1 are directly coupled by indirectly mounting the semiconductor laser and bringing a sub-mount projecting from the dielectric waveguide side end face 13 of the semiconductor laser and the dielectric waveguide 1 into contact with each other.

Abstract: PURPOSE:To simplify a start circuit and, at the same time, to stabilize the phase sequence of a three-phase voltage. CONSTITUTION:At the time of deciding the phase sequence of the three-phase voltage of an inverter device which obtains a three-phase alternating current by coupling a frequency divider type transformer 4 with a single-phase inverter 3 which converts the direct current outputted from a DC power source 1 into a single-phase alternating current, the extent of a DC voltage which permits the operation required for obtaining a three-phase output and the normal rotationally operating area of a frequency-divider type three-phase inverter are found from the relation between the unbalanced state of the ferroresonance circuit of the transformer 4 and the phase sequence of the three-phase voltage and, at the same time, the degree of unbalance of a linear magnetization coefficient that can meet these conditions. In addition, the ferroresonance capacity of the ferroresonance circuit is compensated with a compensating capacity at which the varying width of the linear magnetization coefficient can become 3% by using exciting characteristics which completely vary in the degree of unbalance in the three phases.

Title: Electrically-driven power steering device
Inventor: NORIFUJI YASUSHI
IPC: B62D5/04
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To carry out satisfactory return control without increasing the costs. SOLUTION: A motor 4 for producing a steering assist force to be applied to a steering mechanism is driven in response to PWM drive pulses delivered from a PWM producing part 24. A current detection value of the motor detected by a motor current detecting circuit 6 is offset by an offset producing circuit 8. The degree of the offset corresponds to a PWM duty of the PWM drive pulses. Upon returning of a steering wheel, the motor 4 is rotated through the returning of the steering wheel by a self-aligning torque of a vehicle, so as to generate a power with which the PWM duty is changed. Accordingly, the PWM producing part 24 sets up a PWM duty with which the motor 4 produces a torque for assisting the returning of the steering wheel.
