Filed: 1988-01-22
Abstract: PURPOSE:To improve the efficiency of ion migration and diffusion by impressing a voltage and to shorten the manufacturing time of the title optical device by forming a thin film of an ion-bonded compound instead of a thin metallic film. CONSTITUTION:A thin film 4 made of Ti is formed on the surface of a glass base plate 1 containing, for example, Na<+> and K<+> as a 1st ion 3 and an exposed pattern 41 is formed by removing part of the thin film 4 by etching so as to expose the surface of the base plate 1. Then a thin film 11a made of AgCl which is an ion-bonded compound and another thin film 12 made of Ti, Au, Cu, Cr, etc., are successively formed on the thin film 4. When a voltage is impressed across the base plate 1 from a power source E through an anode 10 and cathode 9 while the base plate 1 is kept in an electric furnace, etc., under a heating condition, the ion bond of the AgCl in the thin film 11a is partially dissociated and a 2nd ion 61a (Ag<+>) is produced. The 2nd ion 61a is migrated and diffused into the base plate 1 and forms an optical waveguide 2a. Therefore, the efficiency of ion moving and diffusion by impressing a voltage is improved and the manufacturing time of an optical device can be shortened.

Filed: 1989-01-20
Abstract: PURPOSE:To reliably prevent the generation of an abnormal reaction force in a given range by a method wherein a work grasping part is coupled to a hand body through a floating mechanism. CONSTITUTION:A work grasping part 2 is coupled to a handle body 1 through a floating mechanism 3. Even when the work grasping part 2 is pressed against a work and a tool and the like, no abnormal reaction force is generated in a given range.

Filed: 1993-01-28
Abstract: PURPOSE:To finish drying at a high drying level without generating static elec tricity by selectively implementing the course in which moisture is applied to the dried clothes by a humidifier for each type of the clothes to be dried after the drying operation and the course in which only the drying operation is performed. CONSTITUTION:A microcomputer judges whether the clothes to be dried are dried or not based on the dryness factor signal inputted from an electrode (S4). When it judges that the clothes are dried, it continues the operation for more 20 min (S5), then it cuts off the excitation of a heater 21 to complete the drying operation (S6). It judges whether the moisture absorbing operation is to be performed or not based on the read result in S1 (S7). If the microcomputer judges Yes, it excites a heater 26 (S10). The water of a humidifier is heated and boiled, and the steam is applied to the dried clothes in a drum as moisture. The dried clothes absorb moisture, static electricity is leaked, and no discharge occurs between fingers of a user when the dried clothes are taken out.

Filed: 1989-01-20
Abstract: PURPOSE:To improve workability at a low cost by providing an elastic member for giving required torque to a switching part while attaching the elastic member removably. CONSTITUTION:A switching part 15 is attached to a body 13 rotatably through a support shaft 14 while it is arranged at a position apart from the shaft 14. One end of an elastic member 24 is engaged removably with the body 13 at a position apart from the shaft 14 while the other end is engaged removably with the switching part 15 at a position apart from the shaft 14. The elastic member 24 energize the switching part 15 to the open position. Since the point of application of elastic force is spaced from the shaft 14 by a long distance, sufficient torque can be applied to the switching part 15 even if the elastic member 24 is small. Further, since the member 24 and the shaft 14 are at different positions, the member 24 can be removed easily indepenetly from the shaft 14. In this manner, a small-sized switching device can be obtained.

Title: Pulse generating circuit
Inventor: KADOWAKI NOBUSATO
IPC: H05B41/24
Filed: 1992-01-28
Abstract: PURPOSE:To protect a switching element in an inverter circuit and to compensate for the duty of pulse wave outputted from a pulse generating circuit. CONSTITUTION:The pulse generating circuit comprises a circuit 6 for switching clocks (a) and (b) depending on the voltage level of an inverter circuit 11, and an output control circuit 5 for turning the pulse output OFF when the voltage level is high. The clock (b) is a signal slower than the clock (a). If the inverter circuit 11 produces a high level signal for 0Hz frequency of clock (b), an ON time counter 3a produces the clock (b) which is not counted. Consequently, pulse output is suppressed and ON time data is retained. Upon transition of the signal from the inverter circuit 11 to low level, the pulse wave rises and the counter 3a begins to count the ON time data thus compensating for the duty of pulse wave.

Abstract: PROBLEM TO BE SOLVED: To make the amount of injection larger as much as possible by a method wherein a molten resin is fed to the tip side of a screw by rotating a first servo motor during the action of an injection process with a second servo motor. SOLUTION: When an injection timing is reached, an injection controlling part 13 starts the driving controlling of a second servo motor through a servo amplifier 14 so that a screw 2 is advancingly driven from its retreat limit position, resulting in starting in injecting and filling the molten resin stored in the tip side of the screw 2. When a metering controlling part 16 recognizes the arrival of the screw 2 to its predetermined advance position, the metering controlling part 16 starts the driving controlling of a first servo motor 3 through a servo amplifier 17, resulting in starting the rotation of the screw 2 and consequently the feeding action of a resin to the tip side of the screw 2.  The molten resin fed into the tip side of the screw during a primary injection process is injected and filled in the mold together with the molten resin stored in the tip side of the screw before the start of injection.
