Title: Ventilating and cooling device for internal pressure explosion-proof electric machine
Inventor: YOSHINO HITOSHI
IPC: H02K9/02
Filed: 1978-10-27
Abstract: PURPOSE: To prevent an electric equipment from stopping even when a blower get throuble by equipping a secondary blower between a plurality of branch ducts at the discharge part of a primary blower and the suction duct of an electric equipment and using either of them as an auxiliary blower.  
     CONSTITUTION: The discharge duct 16 of a primary blower 15 is branched into ducts 17, 18, beyond which are connected respectively secondary blowers 19, 20 and pressure dampers 21a, 22a are equipped on the discharge ducts 21, 22 to connect with the suction duct 13 of an electric equipment 10. At that time those blowers 15, 19, 20 are selected so that each of them can keep the air pressure over the limit of the electric equipment 10. One of them is taken as an auxiliary and can work instantaneously by the pressure drop signal from an internal pressure detector 23 for detecting a slight drop of the internal pressure. Therefore, the electric equipment 10 need not stop instantaneously even though a blow in normal service is broken.

Title: Automatic sheet feeder
Inventor: HAYAKAWA KIMIAKI
IPC: B65H3/52
Filed: 1982-07-28
Abstract: PURPOSE:To feed a successive sheet in a stable manner, by installing a delivery belt and a separation belt standing opposite each other and, when the sheet arrives at the specified position, turning round one side belt in a direction to separate its one end from the other side belt. CONSTITUTION:Placing a bundle of copies on a tray 1, when one side of the front end is inserted into an inlet port (a), the setting of copies mounting is detected by a sensor (lever) 24. Under this condition, when a start button is pressed to ON, a pickup operating shaft 18 is rotated by a solenoid plunger, and thereby an auxiliary roller 7 is made pressingly contact with the front end surface of these copies in a bundle. Next, with cams 28 and 29 turned by 180 deg., a separation belt 17 is lifted to the side of a paper feed belt 6 via a roller 31 and thereby a paper feed driving shaft 2 is made into a state of rotative motion via a roller 34 whereby these copies are fed one by one in regular sequence. And when each paper is fed to the specified position, the separation belt 17 goes down due to rotation of these cams 28 and 29 as far as 180 deg. and thus separation between belts 6 and 17 takes place.

Title: Fm detecting circuit
Inventor: WATANABE KAZUO
IPC: H03D3/00
Filed: 1979-10-15
Abstract: PURPOSE:To improve the whole S/N by providing a couple of FM detecting circuit in parallel and by adding inphase signal components and noise components, which are out of phase at random, together respectively. CONSTITUTION:Since balanced differential multipliers 3 and 3' constituting the quadrature detecting circuit are provided in parallel, the whole detection output is the sum of detection outputs of the both. As a result, since signal components Vs and Vs' of their detection outputs are in phase, the whole detection output can be increased by 6dB. Since noise components Vn and Vn' are out of phase at random,  on the other hand, the whole detection output is increased by only 3dB. Thus, the  whole S/N can be improved by 3dB.

Title: Method for dicing semiconductor wafer
Inventor: KIRIYAMA YOSHIYA
IPC: H01L21/301
Filed: 1983-07-19
Abstract: PURPOSE:To prevent the insulation breakdown of a gate oxide film without the difficulty of the exfoliation of a protection film by a method wherein a semiconductor wafer is diced in the state that polymer series material containing particles made of conductive material is provided on the wafer as the protection film. CONSTITUTION:The wafer 1 with elements such as an FET7 formed is coated with an isoprene cyclized rubber having the addition of carbon particles as the protection film 8 by means of a spinner. Then, the wafer 1 is separated into semiconductor chips with a dicing cutter 9. At this time, static electricity hardly generates because of the friction between the film 8 and the cutter 9. Even if static electricity generates, it is discharged to the wafer 1 via film 8, so there is no posibility of the static breakdown of the gate oxide film 11 due to the charge concentration to the part of a gate electrode 6. Besides, the film 8 on a chip can be easily exfoliated by ultrasonic washing using an exfoliating agent.

Title: Thin-film type squid fluxmeter and biological magnetism measuring instrument
Inventor: YOKOZAWA KOICHI
IPC: A61B5/05
Filed: 1989-05-25
Abstract: PURPOSE:To facilitate the exchange of the SQUID fluxmeters gone out of order by providing a magnetic shield to cover the SQUID elements. CONSTITUTION:The thermally conductive layer of the SQUID fluxmeter substrate 51 of the multichannel cerebral magnetism measuring instrument and thermally conductive wires 80 on a hemispherical structural body 200 come into thermal contact with each other when the substrate 51 is mounted on the surface of the structural body 200. Liquid helium beginning to accumulate in the bottom of a vessel 10 covers the inside of a superconducting thin film through band-shaped thermal conductors 81, the lead wires 80 and the thermally conductive layer at the time of cooling. Since a simple magnetic shielding is executed by a magnetic shield 500, the magnetic trapping of the superconducting thin film itself does not arise. The superconducting thin film, therefore, operates as the magnetic shield in the most initial stage at the time of the cooling and the cooling of the substrate 51 without receiving the influence of the terestrial magnetism and environmental noises is possible. Since the SQUID fluxmeters which are one channel of the multichannel cerebral magnetism measuring instrument are attachable and detachable to and from respectively from the structural body 200, the simple exchange thereof is possible even when the fluxmeters go out of order during use.
