IPC: H01S5/00
Filed: 1990-07-31
Abstract: PURPOSE:To enable a semiconductor laser device to be changed in resonant wavelength and cycle time and controlled in optical pulse repetition frequency by a method wherein DRBs are provided and selected. CONSTITUTION:When the Bragg wavelength of a DRB 21 or a DRB 22 is coincident with the gain peak wavelength of a gain region 20, the DRB 21 or 22 functions as a reflective mirror, a laser oscillation starts, and a semiconductor laser of this design becomes large in optical output. At this point, a formula, (Bragg wavelength) = (refractive index) X (grating pitch), is satisfied, where the refractive index is made to change with an injection current, so that an operating DBR can be selected by controlling an injection current to change a resonant wavelength and a cycle time, in result a semiconductor laser device of this design can be changed in pulse repetition frequency.

Title: Controlling device for grain sorting wind
Inventor: NINOMIYA SHINJI
IPC: B07B11/04
Filed: 1990-07-31
Abstract: PURPOSE:To automate the wind force control in an air sorter which airsorts grains such as husked rice without winnower and to contribute to the all automatic operation of a rice husking sorting machine by controlling a wind force controlling device to the decrease side by the prescribed amount when a grain detector detects grains. CONSTITUTION:Detection information of a grain detector 29 is sent to an arithmetic control part 32 at every prescribed time. When grains are not detected, a wind force increase command signal is output to a wind force controlling motor 28 from this arithmetic control part 32. A wind force control plate 26 is controlled to the increase side by the prescribed amount and wind force is successively controlled to the increase side. When the grain detector 29 detects grains wherein the number of particle detected by the grain detector 29 is larger than the number of reference particle, a command signal for decreasing wind force of prescribed amount is output from the arithmetic control part 32. Sorting wind is weakened and the initial setting of wind force is performed and air-sorting is performed by wind force wherein grains are not flown from a dust discharge cylinder 6. Further even while rice husking operation is performed, the detection information of the grain detector 29 is sent to the atithmetic control part 32 at every prescribed time. When the grain detector 29 does not detect grains or the number of the detected particle does not exceed the number of reference particle, the control command signal of wind force is not output from the arithmetic control part 32.

Filed: 1982-11-24
Abstract: PURPOSE:To obtain a semiconductor laser device of high reliability not depended on ambient temperatures by a method wherein a device is composed of a semiconductor laser element, a P-N junction element used to detect the temperature, and a thermoelectric cooling element electrically connected to the P-N junction element. CONSTITUTION:The semiconductor laser element is formed by stacking the semiconductor laser element 1, a sub mount 2 consisting of an Si crystal piece, and the thermoelectric cooling element 3. By such a constitution, the heat generated from the semiconductor laser element is detected by utilizing that a forward directional voltage VF of the P-N junction diode of the sub mount 2 varies with the variation of the ambient temperaure, the variation of the forward directional voltage VF is fed back to the thermoelectric cooling element, and thus cooling is so performed to a fixed temperature by the thermoelectric cooling element 3 that the semiconductor laser element always emits a prescribed photo output. Therefore, the semiconductor laser element itself is driven in a state of suitable temperature, and then the deterioration of the semiconductor laser element can be prevented.

Filed: 1987-08-20
Abstract: PURPOSE:To secure the gain control of an intermediate amplifier even when imperfect contact is generated in an opening/closing switch, by forming a means which switches an AGC amplifier and a manual control part in a prescribed form. CONSTITUTION:In a switching part 4, the wiring of the AGC amplifier 3 is performed so as to be set at high impedance by a resistor R1, and that of the manual control part 6 so as to be set at low impedance by a buffer amplifier IC1.

Abstract: PURPOSE:To manage with up to 12 DTMF signal generating circuits even when trunk line trunk circuits are increased by generating and inputting 12 dial signals of a DTMF signal to a time-division exchange part individually, and selecting one of the 12 dial signals for each trunk line trunk circuit and sending it out. CONSTITUTION:An address signal is supplied from a clock signal generation part 1 so that the output signal 7 of a ROM 2 is a parallel PCM signal; and the parallel PCM signal 7 is added by a frequency addition part 3 and outputted as a parallel PCM signal 8, which corresponds to the dial tone of the DTMF signal. The parallel PCM signal 8 is converted by a parallel-series converting circuit 4 into a serial PCM signal 9, which is processed by octet multiplexing. Then the time-division exchange part 5 performs the time-division switching of the serial PCM signal 9 and outputs the signal to the trunk line trunk circuits 61-6n. Consequently, even when the trunk line trunk circuits are increased, DTMF signal generating circuits need not be provided exceeding the number of dial tones, i.e., 12.

Title: Manual feed control method for electric discharge machining equipment
Inventor: FURUTA TOSHIMI
IPC: B23H7/26
Filed: 1989-08-09
Abstract: PURPOSE:To facilitate changing of the manual feed speed and to increase the efficiency of positioning operation by changing the feed speed in a manual feed function of an electric discharge machining apparatus only by operating a manual feed start switch. CONSTITUTION:When a manual feed start switch 1 is continuously or intermittently operated, the manual feed speed for a moving shaft, taking the amount of time the switch 1 is operated or the number of times of operation as a parameter is changed according to a predetermined sequence. When a hand is once removed from the manual feed start switch 1, or the non-operation time of the switch 1 becomes more than a preset value, and the manual feed speed becomes more than a preset value, the manual feed speed is returned to the initial manual feed speed. Thus, only by the operation of the manual feed start switch 1, the manual feed start and the manual feed speed can be switched to position an operational object with good efficiency.
