Title: Air-feed apparatus for use in pressure tank
Inventor: MITA YASUHIRO
IPC: F17C5/00
Filed: 1978-01-27
Abstract: PURPOSE: To make practicable safety operation of a pressure tank wherein air-feed tank is arranged in a manner that an air reservoir is remained in an air-feed tank at a water level higher than a miximum water level at the time of a miximum pressure, and water level in the pressure tank is detected by a detection tank.  
     CONSTITUTION: A pump 16 continuously feeds water until the pressure in a pressure tank 1 reaches a miximum pressure. Since an electromagnetic valve 9 is opened and an electromagnetic valve 8 is closed, water in an air feed tank 6 is discharged through the electromagnetic valve 9 and a drain pipe 10, and air is sucked in through an aspiration pipe 13. After a fixed time, a timer opens the electromagnetic valve 8, closing the electromagnetic valve 9. Pressure water in the pressure tank 1 pushes air in an air feed tank 6 into a pressure tank 1 by means of a check valve 7. After another fixed time, a timer closes the electromagnetic valve 8, and opens the electromagnetic valve 9. The above movement is continued until the water level in the pressure tank 1 reaches a minimum level.

Abstract: PURPOSE: To form a trench with a high aspect ratio with a high throughput. CONSTITUTION: NF3 is used as an etching gas in an RIE device and silicon wafer 6 is etched with a side-wall protection film 15 as an etching mask to form a trench 16. At this time, since the side-wall protection film 15 is formed on the inner walls of openings 13a and 14, the anisotropy of ion can be secured, thus forming a trench 16 with a high aspect ratio vertically to the silicon wafer 6. Also, by reducing high-frequency power, the shock force of ion entering the silicon wafer 6 can be reduced, thus preventing the silicon wafer 6 from being damaged. Also, no C is contained in NF3 , thus preventing SiC from being generated as a reaction product and element isolation characteristics of the trench 16 from deteriorating due to SiC.

Title: Paper supply device
Inventor: ITO KENJI
IPC: B65H3/00
Filed: 1986-01-16
Abstract: PURPOSE:To prevent the uppermost one of stacked paper sheets from adhering to a pick-up roller so that it is left alone, by raising the pick-up roller by a some degree in association with the rotation and movement of a paper feed container. CONSTITUTION:When a paper feed container 10 starts to rotate and move from a paper feed position to a paper replenishing position, a pick-roller 30 is slightly raised in association with the rotation and movement of the container. Therefore, when the paper container 10 moves away from the paper feed position, the pick-up roller 30 is surely separated from the uppermost one of stacked paper sheets P, and therefore, it is possible to prevent the uppermost one of the stacked paper sheets P from adhering so that it is left alone. Further, when the paper feed container 10 is at the paper feed position, a release pin 75 lowers together with the pick-up roller 30 as the quantity of the paper sheets is decreased. The lower limit of the release pin 75 corresponds to a position at which the stacked paper sheets P is started to be pushed up by means of a bottom plate push-up mechanism. Accordingly, the bottom of inclined surface y2 of the cam section 12c is set to be lower than the lower limit position of the release pin 75.

Abstract: PURPOSE:To prevent trouble from occurring at a conveyor connection part by detecting that a printed substrate comes to a specified position being carried by a first conveyor when it happens so as to operate a pusher, and transfer the substrate onto a second conveyor. CONSTITUTION:When a printed substrate 8 is processed on a first conveyor 5 by a specified method and comes to a terminal part of the conveyor 5, a sensor 43 detects the state. A motor not shown in a figure moves a pusher mechanism 30 to the downstream (in the direction of an arrow) along a frame 13a, according to the output of the sensor 43. Then, a lever 38 rotates clockwise around a support shaft 34, and a support plate 33 descends to lower a pusher 31 against a spring 32. The lower end of the pusher 31 pushes the rear end of the printed substrate 8 towards a second conveyor 44. It is thus possible to enable delivery of the substrates from the first to second conveyors, even if the size is smaller.
