Title: Roller chain elongation detector
Inventor: MAEKAWA KATSUHIKO
IPC: E04H6/14
Filed: 1994-05-24
Abstract: PURPOSE:To aim at the obviation of any accident by installing a contact plate with a sensor pin in a lower chain guide of an endless chain traveling a pallet or the like in the horizontal direction, and detecting the extent of elongation by means of slackness in the chain. CONSTITUTION:A contact plate 16 energized by a coil spring 12 is installed in a lower roller chain guide 4b of an endless roller chain 2 wrapped on a pair of sprocket (unillustrated herein) via a bracket 6. In addition, a sensor pin 10a connected to a control circuit 14 is installed in this plate 16. Then this plate 16 is always made in contact with the roller chain 2, and when this chain 2 elongates and thereby any slackness is produced there, it is detected by the sensor pin 19a, while if this elongation becomes more than the specified value, the chain 2 is stopped, whereby any possible falling of the pallet due to the slackness is prevented from occurring. With this constitution, a job for detecting the chain elongation becomes facilitated, and thus any possible accident is obviable before it happens.

Title: Current detection for ac servomotor
Inventor: UKON KIYOTAKA
IPC: G01R31/34
Filed: 1986-05-15
Abstract: PURPOSE:To enable a reduction in the cost and in the size while achieving a higher reliability, by detecting a desired one phase of motor current with a current detector to invert the detection value when a PWM current command is 'L'. CONSTITUTION:In a driver for an AC servomotor M which performs a square wave excitation using transistor inverters 1-6, a PWM current command, a rotational direction command and detection signals of pole sensors PU, PV and PW are applied to a base drive signal generation circuit 1. A desired one phase of motor current is detected with a current detector CT to turn an output of an inversion element 3 to 'L'. With such an arrangement, when the PWM current command moves to 'L', an output current value of the current detector CT is inverted to be applied to an operational circuit 2. Thus, a true motor current is obtained as the output of the circuit 2.

IPC: H03G3/02
Filed: 1978-09-06
Abstract: PURPOSE:To ensure the perfect sound arrest at the remote control time by applying the voltage which conducts when the control voltage is under the fixed level to the base side of the transistor connected to the control terminal of the electronic volume circuit. CONSTITUTION:Electronic volume circuit 6 varies the sound volume by the control voltage which is applied to the control terminal and then generates the control voltage via control voltage generation cirucit 1 featuring such characteristics as to become the minimum voltage under the sound arrest control state to apply it to circuit 6. Then the collector and the emitter are connected between the control terminal and the earth of circuit 6 via transistor 15, and the voltage is applied to the base side so that the conduction may be secured when the control voltage becomes under the fixed voltage level. As a result, the impedance of the supply path of the control voltage can be reduced at one time in the range where the sound volume is small, and also the sound arresting function can be secured well at the remote control time to perform the perfect sound arrest.

IPC: G02B6/38
Filed: 1987-05-06
Abstract: An apparatus for terminating an optical fiber includes a resiliently deformable spherical member disposed in contact with a front end of a bore of an optical fiber contact body. Subsequent to softening an adhesive disposed within the contact body bore, an optical fiber is inserted through the bore and the adhesive until the fiber contacts the blocking member and deforms it. The resiliency of the blocking member causes adhesive to be wiped off the front face of the fiber being terminated and into an annulus formed between an outer cylindrical surface of the fiber and an inner cylindrical surface of the bore, and causes the fiber front end to be recessed a predetermined amount from a front end of the contact body.

Title: Fluid medium and its manufacture
Inventor: IKUNO HIROSHI
IPC: C01F7/74
Filed: 1990-04-27
Abstract: PURPOSE:To obtain fluid mediums which are not easily powdered and effect no endothermic reaction due to decarboxylation by determining a particle size of fired particles formed from gypsum, as raw material. CONSTITUTION:Gypsum, as raw material, is heated and dried at a temperature 100-250 deg.C to obtain gypsum hemihydrate or anhydrous gypsum so that granulated matters having constant and stabilized quantity of water required for granulation are obtained. The granulated matters are crushed into particles having a specific surface area of 2,000-8,000cm<2>/g and retardants and hardening agents are mixed into said particles. Water required for granulation is 10-40wt.% of the gypsum. The matters are cured in the atmosphere for more than one day and firing is preferably performed at a temperature 850-1,200 deg.C. By firing the matters, temperature hysteresis is imparted up to an operation temperature and hence generation of CO2 gas due to decarboxylation, when the matters are used in a fluidizing bed, is avoided, so that heat losses of gas and heat losses due to endothermic reaction are eliminated and fluid mediums which are not easily powered due to rapid heating and quenching can be prepared. After the firing, the mediums are screened to obtain a particle size of 0.2-4.0mm.

IPC: H02M1/08
Filed: 1977-09-16
Abstract: PURPOSE: To stabilize control with a turn-off time shortened by supplying signals from a zero-cross-pulse generating circuit and pulse-width modulator circuit to the reset terminal of a saw-tooth wave generating circuit via a reset circuit.  
     CONSTITUTION: Reset circuit 11 is added and supplied with signal (b') from zero- cross-pulse generating circuit 1 and signal (e') from pulse-width modulator circuit 4,  and its output (j) is connected to reset terminal R of saw-tooth generating circuit 5.  As a result, circuit 5 is reset by the 2nd pulse counted from the point in time when output (e') of circuit 4 becomes "O" and (e') becomes "1". Therefore, the number of trigger pulses to be removed by "O" of (e') is two without fail and becomes smaller than it was. This results in that the time while a load current is OFF viewing from current waveform (g') of load 8 is one period invariably and the only ON time is controlled in proportion to signal (d') of detection circuit. Consequently, stable and proportional control is attained by controlling load 8.
