Patent JP-S6373681-A (JP)
Title: Laser oscillator
Inventor: TANAKA SUSUMU
IPC: H01S3/131
Filed: 1986-09-17
Abstract: PURPOSE:To be able to obtain an accurate optical output by a current control system by providing means for adding a current correction by a deviation to eliminate the deviation of a detecting optical output and a set optical output. CONSTITUTION:An arithmetic corrector 7 for monitoring a deviation between the set optical output of an output setter 4 and the detecting optical output of a resonator 1 detected by an optical output detector 6 is provided. When the deviation occurs, a correction amount of a proper output current is calculated to eliminate the deviation, and it is output as a correction signal to a current controller 3. Reference characteristics 11 are obtained by characteristic measuring test after a device is manufactured, and input as initial data to the corrector 7. When the optical output characteristic when the device is actually operated becomes a characteristic curve 12 or 13, the displacement 14 or 15 from the characteristics 11 is calculated as a current correction amount. When the current correction amounts are calculated in advance with respect to the several points of the optical output, the current correcting amount can be immediately obtained for the arbitrary set outputs.

Title: Solid-state laser device provided with thermostat
Inventor: SUZUKI MASAO
IPC: H01S3/042
Filed: 1989-08-25
Abstract: PURPOSE:To enable a solid-state device to normally and stably output laser rays immediately after it is turned ON by a method wherein the temperature of cooling water at the time when the device oscillates laser rays is kept unchanged even while the device stops oscillating. CONSTITUTION:A Q switching element 3 is kept comparatively high in temperature due to the heat release of a transducer while a laser device is in operation. While the laser device is out of operation, the transducer and an ultrasonic medium 12 are controlled in temperature through a heating wire 10 arranged surrounding the transducer and the ultrasonic medium 12 so as to keep the surface temperature of them as high as that at the time when the laser device is in operation. The temperature control is carried out through a digital controller basing on the signals outputted from a thermoelectric element in contact with a pure water tank and a heat exchanger. The heating concerned is stopped concurrently at the time when the laser device starts oscillating, and thereafter the temperature of pure water is controlled by the heat exchanger 8, and the switching element 3, which most remarkably affects the rise and the fluctuation of laser output, is previously heated to keep constant in temperature. By this setup, a laser device of this design can oscillates stably just after it is turned ON and be shortened in rise time until it oscillates stably.

Title: Armature winding of brushless motor and winding method
Inventor: KITAMORI TERUAKI
IPC: H02K3/04
Filed: 1991-08-05
Abstract: PURPOSE:To eliminate cogging torque completely by folding back a coil at one end face of a tubular core whereas passing the coil to the side face of shaft at the opposite end face and winding the coil continuously while rotating the axial supporting core of the tubular core. CONSTITUTION:A core 1 having insulated surface is rotated through a supporting core 4. A coil 3 is passed onto the end face of the core 1 in the arrow direction along an upper guide blade 10 and then passed through the circumferentially opposite face of the core 1 to a part adjacent to the start-of- winding. The coil 3 is then hooked at the edge of a fold-back blade 9 and folded back thus winding the coil sequentially. Since the fold-back blade 9 is fixed, the hooked coil 3 advances in the removing direction as the supporting core 4 rotates. Consequently, the coil 3 is disposed while being arranged on the circumferential face of the core 1. According to the invention, cogging torque can be eliminated completely.

Title: Paper feed device for sheet printer
Inventor: TAKAMATSU HIROSHI
IPC: B65H3/08
Filed: 1987-09-03
Abstract: PURPOSE:To make it possible to completely carry out absorption of a sheet even though a printer is rotated at a high speed, by detecting the high speed rotation of the printer by means of a tachometer, and by rotating a bushing between a valve air chamber and a valve element so that a port and an air chamber is communicated with each other through an elongated hole so as to attain a required degree of vacuum as early as possible. CONSTITUTION:A rotary encoder 36 detects the rotational speed of a printer, and delivers a signal for rotating a servomotor 31 by a predetermined angle corresponding to the rotational speed. Then, a bushing 30 is rotated through a link mechanism 35 so that circumferential phases of elongated holes 30a, 30b vary with respect to ports 15, 16, and accordingly, the time at which an air chamber 13 is started to face the elongated holes 30a, 30b, measured from such a condition that a valve element 14 closes the elongated holes 30a, 30b varies. That is, the time of the valve element 14 starting to face the elongated holes 30a, 30b is earlier during high rotational speed operation of the printer than during low seed rotational speed operation thereof so that the air passes therethrough at an earlier time during high speed operation thereof. Accordingly, a predetermined degree of vacuum is attained early even though the printer is rotated at a high speed, thereby suction through suction ports 4, 5 may be completely made.

Title: Sand surface measuring method for sand pile construction method
Inventor: TANIGUCHI TADAO
IPC: E02D3/10
Filed: 1992-07-28
Abstract: PURPOSE:To improve the workability by automatically controlling the delivery speed of a wire rope, to which a weight is fitted to the lower end thereof, at a set value or less at the time of hanging down the wire rope into a hollow pipe for the construction of sand pile to detect the height of the sand surface on the basis of the delivery quantity of the wire rope. CONSTITUTION:The wire rope delivery speed Vx of a take-up drum 18, which can stop the lowering of a weight 5 instantly, is set in an exclusive driver 19 previously. Next, in the case where the weight 5 is fallen naturally between a distance L1 and the lowering speed Vo exceeds the preset delivery speed Vx, it is detected and the drum 18 is rotated by a motor 17 made of a megatorque motor. Next, at this stage, the drum 18 is controlled by the predetermined torque reverse to the rotation direction on the basis of the torque signal sent from the driver 19 to the motor 17. The weight 5 is lowered at the set speed Vx between a distance L2 until it abuts on the sand surface to detect the sand surface. The lowering speed of the weight 5 is thereby speeded up, and since the lowering speed is controlled automatically, the control is easy, and the drum can be stopped instantly to measure quickly, and the accuracy is improved.

Title: Liquid level detecting device
Inventor: TSUJI HIROYUKI
IPC: G01F23/00
Filed: 1982-12-14
Abstract: PURPOSE:To ensure the detection of a liquid level in a broad temperature region, by changing the number of counting or a measuring time by the liquid temperature. CONSTITUTION:A liquid temperature is detected by a temperature detecting element 23 and converted into a digital value by an AD converter 26 through an amplifier circuit 25. The result is inputted to a counter circuit 18, which can be preset, and the counted value with respect to the liquid temperature is set. The setting is automatically performed so that the value is small when the liquid temperature is low and the value is large when the liquid temperature is high. The counting circuit 18 counts the output pulses from a pulse circuit 16. When the counted value reaches the preset value, the value is outputted to a holding circuit 19 and an output circuit 14, and warning is issued to the outside. When the liquid temperature is low and the self-heating power of the liquid level detecting element 6 is insufficient, the counting times are set in small value and the reference is changed. Therefore, the operation without errors is ensured in the broad temperature region.
