Title: Searching system for fault of repeating transmission line
Inventor: FUJIWARA HARUO
IPC: H04B17/40
Filed: 1984-09-12
Abstract: PURPOSE:To attain the return of a fault searching signal even at a place where no repeater is provided by providing an optical switch at a point of a distance L/n decided by dividing the repeating distance L of a repeater by the number (n) of bidirectional transmission lines. CONSTITUTION:The searching signals are transmitted from end offices 20 and 21 and fed back through each repeater, and the searching distance is reduced down to a single repeating distance L. A drive signal of a specific frequency is transmitted to a switch control circuit 11 from the office 21. The circuit 11 confirms said drive signal and drives a switch 18 to secure connection be tween the ascending and descending transmission lines 13a and 13b. Then a searching signal is sent to the line 3b and then fed back to the office 21 via the switch 18 and the line 13a. Thus it is decided that no fault is detected in a route between the switch 18 and a repeater 7. Here a fault is detected in a route between a repeater 3 and the repeater 7 and no fault is detected in a route between the switch 18 and the repeater 7. Therefore it is known that a faulty transmission line exists in the route between the repeater 3 and the switch 18.

Abstract: PURPOSE:To miniaturize a sensor and to quantity low concn. glutamic acid, by using glutamine synthetase as enzyme and using a pH glass electrode or an ion responsive electric field effect transistor as a transducer. CONSTITUTION:An ion responsive electric field effect transistor ISFET1 having glutamine synthetase immobilized thereon and a reference ISFET2 having no glutamine synthetase are immersed in a buffer solution having an ammonium- containing salt and adenosine-5'-triphosphate dissolved therein. Further, a Ag/ AgCl electrode 3 is immersed therein in order to keep the potential of the solution constant. Specific voltage is applied between the sources and drains of ISFETs 1, 2 and applied to the electrode 3 and temp. is made constant to add an L-glutamic acid solution being a specimen. Whereupon, reaction is generated at the interfaces of ISFETs and pH changes locally. This change can be measured as the differential output values of the electrodes 1, 2. By this method, a sensor can be miniaturized and low concn. glutamic acid can be quantified.

Abstract: PURPOSE:To decrease a leaking current between neighboring photoelectric conversion elements, which poses a problem when high density is implemented, effectively, by projecting light from the side of a common electrode, and provid ing high resistance in an amorphous semiconductor film. CONSTITUTION:On a light transmiting substrate 1 such as a glass substrate, a discrete electrode 2 comprising an opaque metal material such as Cr is formed. Then, a belt shaped amorphous semiconductor film 3, e.g., a hydrogenated amorphous silicon film, is formed so as to cover the entire discrete electrode 2 by a plasma CVD method and the like. Then, a common electrode 4 comprising a transparent conducting film such as an ITO is formed so as to position at least on the amorphous semiconductor film 3 by a sputtering method and the like. After all the temperature increasing processes are finished, light at, e.g., about 60,000 lux, is projected from the opposite side of the substrate 1, i.e., from the side of the common electrode 4, for about one hour, and the amorphous semiconductor film 3 is exposed. The part of the amorphous semiconductor film 3 exposed to the projected light becomes a high resistance layer 3' by an optical deterioration effect.

Title: Semiconductor manufacturing apparatus
Inventor: HONDA JIRO
IPC: H01L21/027
Filed: 1990-07-17
Abstract: PURPOSE:To prevent an etching defect from being caused in a next process and to increase reliability in terms of a quality by a method wherein a gas- spraying port which sprays a gas on the peripheral edge on the rear of a substrate is installed at a guard for a spin head which is turned at high speed. CONSTITUTION:A spin head 3 is installed inside a guard 11 so as to be freely turned. Gas-spraying ports 12 which spray a gas on the peripheral edge on the rear of an Si substrate 5 on the spin head 3 is installed at the guard 11; opening parts 13 are formed on both sides of the spin head 3. When the spin head 3 which is turned at high speed is turned at reduced speed, a gas is sprayed on the peripheral edge on the rear of the Si substrate 5 on the spin head 3 from the gas-spraying ports 12 as shown by arrows A's, and it is possible to restrain a photoresist liquid 4 from dripping. That is to say, it is possible to remove the photoresist liquid 4 which is going to creep to the peripheral edge on the rear from the peripheral edge on the surface of the Si substrate 5 when the spin head 3 is turned at reduced speed. Consequently, since the photoresist liquid 4 does not adhere to the peripheral edge on the rear of the Si substrate 5 at a photoresist coating process, it is possible to prevent an etching defect from being caused in a next process.

Abstract: PROBLEM TO BE SOLVED: To provide satisfactory acoustic characteristics, while the height of a loudspeaker system is kept low and a wider listening area is secured by turning low-frequency sound speakers, which are horizontally arranged face inside with a specified opening angle. SOLUTION: Low-frequency sound loudspeakers 1A and 1B are arranged above a high sound speaker 3 as a group and low sound speakers 2A and 2B are arranged below the high sound speaker 3 as a group. They are set equivalent and coaxial. The low-frequency sound speakers 1A, 1B, and 2A, 2B are respectively horizontally arranged, and moreover they face each other inside with opening angles α. The four low-frequency sound speakers 1A-2B are connected so that the same signals are added. The opening angle α is set between 150 degrees and 110 degrees. The angle is decided by considering the setting of a speaker diameter, a use band and a listening area. Then, the change of sound pressure owing to the two causes of a distance and directivity is mutually compensated, and the movement of a sound source can be eliminated by appropriately selecting the opening angle α.

Title: Switch driving mechanism
Inventor: SASAKI SHINJI
IPC: H01H3/26
Filed: 1993-08-03
Abstract: PURPOSE:To eliminate the possibility of inadvertent electric shock by surely cutting the high voltage power supply of an external circuit which is to be switched when the power source of the circuit for driving switch is cut off. CONSTITUTION:A main switch 4 is switched ON/OFF by operating the working switch 2 ON/OFF in a car. Even when a power source 1 is cut off by unintended cause such as static discharging when the switch 4 is turned ON, the engagement between a contact point driving lever 5 and a worm gear 10 is canceled by cutting the electrification to a solenoid 8, to separate a mobile contact point 4a and a fixed contact point 4b by the resiliency of a return spring 7. The switch 4 is automatically switched to an OFF mode. Namely, when the power source 1 is cut off, the high voltage power supply 16 of the circuit 15 for driving main motor is also cut off, and the safety is thus improved.
