Title: Semiconductor laser device system
Inventor: YOSHIDA ICHIRO
IPC: H01S5/00
Filed: 1992-06-08
Abstract: PURPOSE:To make the life of a semiconductor laser long and to enhance the operating reliability of a system using it as a light source by a method wherein individual laser resonators are driven respectively independently as currently used ones and as spare ones and, when a currently used laser resonator is deteriorated, it is changed over sequentially to a spare laser resonator. CONSTITUTION:A drive changeover means 3 drives and stops a currently used laser resonator on the basis of an instruction signal which is output from a deterioration detection means 2. It changes over and drives a spare laser resonator in the remaining part according to the predetermined order of priority. It is used as a new currently used laser resonator. For example, a laser resonator which includes a second stripe region 16 is used as a currently used laser resonator. Concretely, a driving electric-power changeover circuit 3 which supplies electric power to electricity-feeding terminals 18a to 18c as driving parts for individual laser resonators is used, and the supply drive parts are changed over by timing that a deteriorated laser resonator does not radiate a beam. Since spare parts are assembled in a semiconductor laser 1 itself in this manner, the constitution of a device is simplified, and a laser beam can be radiated for a long time and stably.

Title: High tension dc power apparatus
Inventor: KUMAZAWA MASAMITSU
IPC: H02M7/12
Filed: 1987-06-12
Abstract: PURPOSE:To make a reactor for limiting rush current to be useless by applying a high frequency current output of a current type inverter to a stray capacity through a step-up transformer to convert it into a voltage output, and by rectifying aud smoothing the voltage output. CONSTITUTION:In a high tension DC electric power apparatus, an input connection of a phase-controllable converter 1 is connected to a three-phase AC power source 10. And, the output of the converter 1 is supplied to terminals 7 through a smoothing reactor 2, a current type inverter 3, a step-up transformer 4, a rectifier 5, and a smoothing capacitor 6 so that a high tension DC voltage is obtained from the output of the terminals 7. This current type inverter 3 comprises switching devices 3a-3d of a thyristor, and permit a secondary stray capacity of the step-up transformer 4 to produce reactive power for commutation. Thus, in the input side of the inverter 3, though it is necessary to employ the smoothing reactor 2 having a large reactance value, a smoothing capacitor is useless, thereby the number of the parts needed for the apparatus is reduced, and the oscillation of the output is eliminated.

Filed: 1990-06-07
Abstract: PURPOSE: To realize sufficient resistance to bowing, twisting, etc., distorting a force transmitter in undesired direction by making a force along a symmetrical plane operate on a force detector and distributing the force by half to a transmission member. CONSTITUTION: As a force Fi along a symmetrical plane 33 acts on a force detector 43, the force Fi is distributed by half to two transmission part 49 during transmission. Therefore, the two pins starting from a stationary position distorts in the direction parting for equal distance from the symmetrical plane 33 in parallel with the plate plane, in other words, parallel with action points connecting line 71 and so, sum of the interval of two action points 61a and two displacement lengths become large. Thus, each half of the arc is extended by the force generated by the transmission and conversion of half of the force Fi . So in addition to a certain original stress or static force generated by elastic prestress, a variable force F0 proportional to the force Fi work on the arc.  As the results, the total force acting on the arc becomes an equal tension force to the sum of the static force and the force Fo .

Title: Tape mounting state inspecting instrument
Inventor: MARUYAMA KAZUO
IPC: G11B15/43
Filed: 1985-07-04
Abstract: PURPOSE:To make possible simple and reliable inspection of a tape mounting state by discriminating a tape stop state by imparting a constant tension to the tape wound on a reel hub. CONSTITUTION:The tape travels a prescribed length within a prescribed time interval, and an FF1 is reset upon termination of counting by a counter CT1. As a result the rapid traverse for inspection is released and an L-output is obtained by resetting of an FF1. A mechanical braking instruction signal is issued and the tape travel is terminated. The output of a circuit 19 goes to L by the stop of tape travel, the output of a gate AND3 goes to L and an FF2 is reset. On the other hand, the output goes to H, the braking is released by the L-output of an inverter IN7 and FF3 is set so that the output goes to to H, the braking is released by the L-output of an inverter IN7 and FF3 is set so that the output goes to L. A constant tension stop mode instruction is outputted by this L-output from inverter IN3 so that a constant tension is produced in the tape. The tape does not run when the brake is released, in case the tape mounting state is normal. If the mounting state is not normal, a non-mounted tape display lamp 22c is lighted so that it becomes necessary to reapply the tape.

Title: Method of controlling hot water surface and hot water temperature in bath tub of resin container
Inventor: NAKAMORI YUKIO
IPC: F24H9/20
Filed: 1987-06-16
Abstract: PURPOSE:To enable the hot water level and the hot water temperature to be controlled with a convenient method by a method wherein a sensor is fixed to a wall of a bath tub. CONSTITUTION:One or more temperature sensors are arranged either at an outer wall of a bath tub or at a corner part within the bath tub and a mean temperature of hot water temperature is accurately assumed in combination with a water level meter in response to a measured temperature value. The hot water level detection is performed such that an AC oscillator 3 is connected to one electrode, a current amplifier 4 is connected to another electrode and an electrostatic capacitance between the electrodes is measured. Electrostatic capacitance type detectors 1-5 and 1-6 are fixed to a wall of a bath tub 20. The detector 1-5 corresponds to a position of a target hot water level and the detector 1-6 is used for preventing a non-water firing. When no water is present within the bath tub 20, an electrostatic capacitance of the bath tub 20 itself is 3-6 of a dielectric constant of a resin system. As the hot water surface level rises up to a position of a detecting end, the electrostatic capacitance becomes more than ten times due to the fact that a dielectric constant of water is 70-80. Measurement of hot water temperature within the bath tub is performed under an arrangement in which a temperature detector, for example, a thermocouple or a thermistor ro the like is fixed in series against an outer wall of the bath tub at 1-1-1-4. Thus, a means hot water temperature can easily be measured.
