Title: Semiconductor laser device
Inventor: MORI KAZUKOTO
IPC: H01S5/00
Filed: 1987-10-09
Abstract: PURPOSE:To produce the output of a single longitudinal mode oscillation to be as a multi-longitudinal mode not mode-competed therewith by forming the phase of a laser beam emitted from one end face of a semiconductor laser chip having a pair of resonator end faces at random, and feeding it back into the chip. CONSTITUTION:The part of a rearward irradiated laser light 5 radiated from the end face 3 of the resonator of a single longitudinal mode oscillation semiconductor laser chip is reflected on the concave face of reflecting means 6 to tend to be fed back to the chip 1, but since the concave face of the means 6 is roughened, the phase of the fed back laser light becomes at random. The feedback rate of the fed back laser light can be regulated to 0.3-1% by regulating the distance of the end face to the concave face of the means 6 and the curvature of the concave face. Thus, RIN(Reflective Intensity Noise) of the noise component of the central frequency in an AM noise can be sufficiently reduced as compared with the case that the fed back laser beam is not present, the fed back light is coupled with a natural radiation light in the chip, and a laser beam of multi-longitudinal mode not mode-competed therewith is output.

Title: Coherent demodulator with carrier-wave regenerative digital circuit
Inventor: PATORITSUKU BUANDAMU
IPC: H04L27/00
Filed: 1992-08-31
Abstract: PURPOSE: To stabilize the operation of a coherent demodulator and, at the same time, to improve the performance of the demodulator by completely constituting the demodulator in a digital circuit. CONSTITUTION: A coherent demodulator samples intermediate frequency signals X and Y from a demodulation circuit CD at a reception frequency from a rhythm reproducing circuit 22, converts the sampled signals into digital signals by means of A/D converters 23a and 23b, and supplies parallel outputs BE1 and BE2 to a digital phase shifter 24. The phase shifter 24 detects error signals BU and BD from the output signals BE1 and BE2 by means of a comparator 25 and shifts the phase of the input signals by using a demodulated phase obtained through a phase loop digital processing circuit 26. Therefore, the operation of the demodulator can be stabilized and, at the same time, the need of the redefinition of a loop by changing the modulating speed as an operating characteristic independent from the modulating speed of received signals can be eliminated.

Abstract: PROBLEM TO BE SOLVED: To save fuel and the like for generating energy by driving a power generator and the like by force increased by circular rotary motion of an inclining shaft as a lever applying to a principle of a lever. SOLUTION: In a lever, one end of a lever rod is vertically operated around a supporting point, and thereby, point force of the other end of the lever is doubled, and large force is generated with comparatively small force.

The other end part of the inclining shaft 7 is received on a sphere 2 which is arranged on an axis of the shaft 5 and which is supported by roll bearings 1, 1. A rotary torque increased by turning motion of the inclining shaft 5 is taken out from a shaft 8, and a power generator and the like are driven by its rotation.

Abstract: PURPOSE:To make it possible to measure a short distance without the effect of reverberation by providing an auxiliary driving means for removing the reverberation which vibrates an ultrasonic wave piezoelectric transducer in a phase which is reverse to the driving phase by a driving means. CONSTITUTION:A switch circuit 3 switches the state which outputs an oscillation output signal that is switched with a switch circuit 5 and the state which outputs the signal whose phases is inverted with a phase inverting circuit 6. The signal is the oscillation output of an oscillation circuit 9. During a period wherein the signal outputted from a reverberation removing timer circuit 4 is at an L logic level, the circuit 3 is switched to the oscillation output side of the switch circuit 5. During a period wherein the signal is at an H logic level, the circuit 3 is switched to the side of the phase inverted signal. The output of the circuit 3 is appropriately amplified with a driving circuit 2, and an ultrasonic wave piezoelectric transducer 1 is driven. Thus the ultrasonic wave is oscillated. The oscillated ultrasonic wave is reflected from a material to be measured and received with the piezoelectric transducer 1. The signal is inputted into an amplifier 11 in a receiving part 15.

IPC: H02K29/14
Filed: 1992-09-25
Abstract: PURPOSE:To obtain an index sensorless motor having high rotational accuracy by forming a magnetization pattern for torque generation separately from a magnetization pattern for rotating field generation timing detection and detecting a magnetization pattern for index signal detection through one specially provided magnetization border part. CONSTITUTION:A hall element 4 is located below the part 1a of a rotor 1 on the outside of a magnet 2 where the part 1a serves as a magnetic shield for preventing flux leakage from the magnet 2 or a coil 15 to a magnetic head. Part 2a of the magnet 2 is magnetized radially and the magnetization pattern is altered at one point on each of the inner peripheral face 2a-1 and the outer peripheral face 2a-2 of the magnet 2. Consequently, cogging torque being produced through interaction of a slot 14 and the part 2a-1 on the inner peripheral face of the magnet 2 decreases because of the magnetization pattern of constant pitch and the magnetix field detected through the Hall element 4 generates an index signal for each revolution from the part 2a-1 on the outer peripheral face of the magnet 2.

Abstract: PURPOSE:To obtain an electric power source device for a welding machine which is small in size and light in weight, is easily operatable and runs with less noise by using a storage battery as a main welding power source and charging the battery by an engine generator under change-over control when the capacity thereof decreased. CONSTITUTION:A voltage detecting circuit 30 in a means 14 for controlling changing- over of charging and discharging detects the need of charging and the output thereof turns on when the charging is needed. A control signal is then outputted to control signal output terminals e, f. (A relay contact 32A is held open in this stage.) Relay contacts 26A, 26B are thereby turned on and therefore the DC current from the output terminal (a) of the engine generator flows through the contacts 26A, 26B as shown by an arrow X. The prescribed charging to the storage battery 12 is thus executed. The load current flows to a primary choke coil 28A of a means 16 for detecting and controlling the load current when the welding operation is started. A prescribed pulse for setting is then induced in a secondary coil 28B at the rise thereof and a normally closed contact 32A is opened. The relay contact 26A remains off and the discharge from the battery 12 is executed as shown by an arrow Y, by which the welding operation is continued.
