Title: Power controlling system
Inventor: KITANO YOSHIHIRO
IPC: H02J1/00
Filed: 1983-09-29
Abstract: PURPOSE:To perform power supply to an input-output device installed to a remote place from the main body of an electronic computer, by installing a no- break power supplying means, such as a battery, etc., to the connecting device of optical fibers. CONSTITUTION:The main body 1 of an electronic computer is connected to a connecting device 6 through another connecting device 4 and an optical fiber transmission line 5. Only a circuit of the connecting device 6 which receives signals from the transmission line 5 and detects whether an optical signal exists or not, is always set to an operable condition by means of a battery 7. If the connecting device 6 detects an optical signal coming from the transmission line 5 when input-output devices 8a-8n and the connecting device 6 are set to a condition where the AC power supply is cut off, the connecting device 6 performs its own AC power supply and succeedingly issues a turning-on command of AC power supply to the input/output devices 8a-8n. Therefore, power supply to an input/output device installed to a remote place from the main body of an electronic computer can be performed.

Title: Solenoid valve control circuit of ink jet printer
Inventor: ARAKI SHIGEYUKI
IPC: F16K31/06
Filed: 1986-08-01
Abstract: PURPOSE:To prevent the dripping of ink when a power source is turned OFF, in performing the return control of a self-holding solenoid at the OFF-time of the power source, by performing the opening and closing control of a solenoid valve by detecting the turning-OFF of the power source before the extinction of control voltage. CONSTITUTION:In a control circuit 30, the turning-OFF of a power source is detected by a power-OFF detection circuit 20 before the extinction of control voltage and a solenoid valve 35 is closed. For example, when a current flows to the solenoid valve 35 in an A-direction, a solenoid is attracted to open the valve and, when a current flows in a B-direction, the solenoid returns to close the valve. A preferential logic 34 is a circuit constituted so that the turning-OFF of the solenoid valve is made preferential even when the signal from the ink jet printer control circuit 30 is outputted when the power source is turned OFF. As mentioned above, electromagnetic force is unnecessary when the solenoid valve is attracted and there is no effect on a head due to the heat generation of the solenoid and, at the time of power-OFF, the solenoid valve can be certainly closed.

Title: Fusion splicing method for multifiber optical cable
Inventor: YAMAZAKI CHIKAFUMI
IPC: G02B6/255
Filed: 1991-06-26
Abstract: PURPOSE:To perform the splicing work while automatically monitoring whether the spread width in the fiber lengthwise direction of a discharge pattern is deviated from a set range or not at the time of fusion splicing of multicore optical fibers due to discharging energy.

Abstract: PURPOSE:To considerably thin off the film thickness of the photoresist with which a mask pattern will be formed by a method wherein an alumina thin film having an excellent resistance for dry-etching property is used as a mask. CONSTITUTION:An organic solvent medium containing aluminum is coated on the silicon dioxide film 12 formed on a semiconductor substrate 11 by performing a recoating using a spin-coating method. Then, an alumina thin film 13 is formed in an oxygen atmosphere by performing a heat treatment. Subsequently, a photoresist is coated, and a resist pattern 14 is formed by performing an exposing and developing process through a photomask using an ordinary technique. Then, an etching is performed on the alumina thin film 13 using an ion milling or an argon (Ar) sputtering etching. At this time, using the alumina thin film 13 left under the resist pattern 14, the resist patterning 14 is also thinned off by etching. Then, the silicon dioxide film 12 is etched by performing a reactive ion etching using Freon (CF4) gas. As the alumina thin film 13 left by performing the above-mentioned process is a thin insulator, there arises no hindrance even when it is left thereon.

Filed: 1987-07-24
Abstract: PURPOSE:To enable detection of even a fine pressure with a sensitivity greatly heightened, by providing a second diaphragm to impart a pressure received therewith to a silicon diaphragm as intensively concentrated load through a columnar protrusion. CONSTITUTION:The tip of a columnar protrusion 6a of a second diaphragm 6 is made to abut the center of a silicon diaphragm 1.

Title: Thermal recording material
Inventor: HOTTA YOSHIHIKO
IPC: B41M5/36
Filed: 1986-08-05
Abstract: PURPOSE:To enable formation of a high contrast sharp image free from any surface deposition despite an increase in the quantity of organic low-molecular substance by providing a resin layer on a laminated thermal member. CONSTITUTION:A thermal element is formed on a support 1 as a thermal layer 2. In addition, a resin layer 3 is provided on the thermal layer 2 in a laminated thermal member obtained in this way. Alternatively, a resin layer is provided respectively on both sides of the laminate thermal member with a thermal element formed in the form of film or sheet. Consequently, even if the quantity of organic low molecular substance in the thermal element is increased, no deposition on the surface will occur. After the whole thermal layer 2 is heated to a temperature between T1-T2, it is cooled to a room temperature of T0 or lower so that it may become transparent. Then it is heated by means of a thermal head into an image form, which is in turn opacified. This results in the formation of a white image in the thermal layer. Finally the image becomes a high contrast one without deposition of an organic low molecular substance on the surface of a recording material by providing an additional resin layer 3 on the thermal layer 2.
