Title: Optical coupler and photoelectronic device with optical coupler
Inventor: TAKAHASHI SHOICHI
IPC: G02B6/42
Filed: 1989-10-30
Abstract: PURPOSE:To obtain always optical coupling efficiency with good reproducibility even if the attachment and detachment of the plug of an optical coupler and the sleeve of a receptacle are repeatedly executed by providing at least one fixing bodies which bring the front ends thereof into elastic repulsion contact with the outer periphery of the plug in the sleeve. CONSTITUTION:The outer peripheral surface of the plug 2 inserted into the sleeve 9 is pressed elastically repulsively by the fixing bodies 5 provided in the sleeve 9 and, therefore, the plug 2 is supported at three points; a part of the inner peripheral surface of the sleeve 9 and the two fixing bodies 5. A part of the inside wall of the sleeve 9 is always used so the reference for the fixing position of the plug 2. The plug 2 is inserted and fixed always to the specified position even if the insertion and removal of the plug to and from the sleeve 9 are repeated. The optical coupling of the high efficiency is thus obtd. with good reproducibility. Since the front ends of the fixing bodies 5 in contact with the plug 2 are smoothed, the outer peripheral surface of the plug 2 is no flawed even if the insertion and removal of the plug 2 are repeated. The fluctuation in the optical coupling efficiency due to in the surface damage is thus eliminated.

Abstract: PURPOSE:To enable highly accurate measurement of a blood stream in a non- invasion manner by a method wherein an organic tissue is irradiated with intermittent light to generate a sound from blood therein and a flow velocity of the blood is calculated from the frequency of the sound. CONSTITUTION:A sensor 1 is mounted on the skin of an examinee and then, when a drive circuit 5 drives a light emitting element 3 to generate a intermittent light being interrupted by a frequency (f) in the light emitting element 3, a part which is blood in a blood tube 12 and irradiated with light from the light emitting element 3 absorbs the light, causing a sound with a frequency (f) to be generated. The sound is converted into an electrical signal with a microphone 4 and amplified with an amplifier 6, and the component of the frequency (f) is cut off with a filter 7 to make one input of a differential frequency counter 8. Then, the differential frequency counter 8 outputs a difference of frequency between both the signals from an output of the filter 7 and an output of the drive circuit 5. Then, a flow velocity calculation circuit 10 calculates a flow velocity of the blood based on an output of the differential frequency counter 8. This, constitution enables highly accurate measurement of a blood stream in a non-invasion manner.

Title: Optical disk device
Inventor: TERADA AKIO
IPC: G11B7/12
Filed: 1989-11-01
Abstract: PURPOSE:To protect an actuator from being burned by measuring the temperature of an actuator itself by using the terminal voltage and the driving current of an actuator coil, and stopping at least the operation of an optical head when the temperature exceeds allowable temperature. CONSTITUTION:The terminal voltage of the actuator coil 4 is measured, and the internal resistance of the actuator coil is calculated from the voltage value of the coil and the driving current of the actuator coil 4. Then, the temperature of the actuator coil is calculated with the resistance value by using the temperature characteristic of the internal resistance of the actuator coil 4. When the temperature of the actuator coil 4 exceeds a prescribed value, at least the operation of the optical head is stopped. Thereby, it is possible to prevent the actuator coil burned when the temperature of the actuator coil 4 exceeds the allowable temperature due to the application of oscillation over specification, etc.

Title: Bisurface copying machine
Inventor: OKUZAWA TSUGIO
IPC: B65H29/60
Filed: 1985-12-18
Abstract: PURPOSE:To enable bisurface copying operation and doubly copying operation, by bifurcating and connecting a reversing path including a second intermediate tray between a guide path in a paper refeed section and a copying section. CONSTITUTION:A bifurcating and reversing pass 22 is formed intermediate of a guide path 19 in a paper refeed section 17, and a second bifurcating plate 23 carries out the change-over. The bifurcating and reversing path 22 reverses a copying sheet so that the upper surface of the copying sheet which has faced up in a first intermediate tray 10 is turned into the lower surface thereof, and is then fed. After a predetermined number of copying papers having been copied on one surface thereof being stacked in the first intermediate tray, when a multi-copying button is depressed, a second bifurcating plate 23 closes the conveying path 19 but open the bifurcating and reversing path 22 to feed the copying sheets into the second intermediate tray 25 one by one. Then these copying sheets are fed into a copying section 2 through a reverse return passage 30 and the conveying path 19. Thus, the copying sheet is once reversed in the first intermediate tray 10 and is reversed again in the intermediate tray 25, and therefore, copy may be carried out such that an image may be superposed on the same surface as the first surface. With such a simple structure, it is possible to change a bisurface copying machine into a multi-function copying machine.

Filed: 1992-10-22
Abstract: PURPOSE:To make the rush current constant regardless of fluctuation of the AC power supply voltage upon short circuit of a current limiting resistor during transient charging interval of a smoothing capacitor in a rectifier circuit. CONSTITUTION:The voltage of a smoothing capacitor 5 is divided through resistors R3, R4 to produce a voltage Vc which is then compared through a comparator 11 with a reference voltage V3 obtained through series resistors R1, R2 and a constant voltage diode ZD. Output from the comparator 11 excites a relay 12 to close a contact 12a thereof thus short-circuiting a current limit resistor 4. Difference between the output voltage from a rectifier 3 with the current limit resistor 4 being short-circuited and the terminal voltage of the smoothing capacitor 5 is kept constantly at a level designated by the constant voltage diode ZD thus sustaining constant the fluctuation of capacitor charging current due to short circuit of the current limit resistor 4.

Abstract: PURPOSE:To stably obtain a product of optimum degree of alloying by a simplified means by increasing the heating and temp.-rise rate of a steel strip in a heating zone of an alloying furnace to a specific value or above. CONSTITUTION:A steel strip 1 galvanized in a zinc bath 2 is subjected to alloying treatment by means of an alloying furnace 4 having a heating zone 5 and a holding zone 6, by which an alloying galvanized steel strip is obtained. In the above method, the heating and temp.-rise rate of the steel strip 1 in the heating zone 5 is regulated to >=2 deg.C/sec. By this method, the transition temp. of emissivity moves to the high-temp. side and the emissivity is held constant until a temp. of 420 deg.C at which plating is melted to the vicinity of 550 deg.C is reached. As a result, at the time of measuring the temp. of the steel strip 1 by means of a radiation thermometer 7 at the outlet of the heating zone 5, the true temp. of the steel strip 1 can be measured and the purpose can be accomplished. When the above heating and temp.-rise rate is lower than 2 deg.C/sec, the transition temp. of the emissivity becomes <=500 deg.C and a temp. at which alloying is performed and xsi-phase is formed cannot be reached.
