Title: Temperature-sensitive relief valve
Inventor: KODAMA HISASHI
IPC: G05D16/04
Filed: 1981-03-04
Abstract: PURPOSE:To keep hydraulic power constant by changing the position of a valve spring by a soil spring formed of bimetal corresponding to a temperature. CONSTITUTION:When the temperature rises, the length of a coil spring 15 formed of bimetal is increased, so that a valve spring 8 is pushed toward the right through a retainer 14. Therefore, a valve 9 moves to the right to reduce the area of an escape hole 10, so as to lessen the quantity of oil which is about to escape in large quantities through the escape hole 10, because a temperature rise causes the density and viscosity of oil to lower, whereby pressure P is kept constant. When the temperature falls, the valve spring 8 and the valve 9 are pushed by oil pressure to move to the left, so that the opening area of the escape hole 10 is changed corresponding to the temperature, whereby pressure P of the oil is kept constant.

Title: Information input device
Inventor: FUJITA MINORU
IPC: G06F3/0488
Filed: 1985-02-21
Abstract: PURPOSE:To facilitate matching of pen positions by securing a monitor display for a character graphic recognizing frame when necessary and also to omit special frame paper, etc. and therefore to attain the quick and accurate input of characters. CONSTITUTION:A switch 3 works in response to the writing pressure of a pen. In other words, a signal R is kept at a low level as long as mere contact is secured between a tablet 1 and the pen top. Thus the coordinate output [x, y] is not equal to pattern information and the display of the corresponding frame can be recognized. When the writing pressure of the pen is increased, the signal R is turned to a high level. Then the output [x, y] is equal to the pattern information and the input of characters is possible. Here the frame once displayed is shown continuously regardless of the subsequent change of the output of the switch 3 until the pen top gets out of the area of the corresponding frame.

Title: Lubricating system for engine
Inventor: WATANABE JITSUO
IPC: F01M1/10
Filed: 1984-02-23
Abstract: PURPOSE:To prevent oil from temperature rise in the normal running of an engine by providing an oil reservoir having stored oil amount controlled by a drain valve to increase the effective oil amount in an oil pan in the cool engine while decreasing the oil amount in the hot engine. CONSTITUTION:In the normal running of an engine 10, since a relief valve 42 and a drain valve 50 in a filter unit 28 provided integrally with an oil reservoir 44 are closed, oil introduced into the filter unit 28 from an oil inlet 32 is filtered through a filter 40 and then flows into the reservoir 44 from an inlet 48 to be stored therein. When the engine 10 is stopped under this condition, oil in the reservoir 44 is sent to an oil pan 18 by fine amount through a leak port 58. Also, in cold start of the engine since the viscosity of oil is high and oil pressure in the oil inlet 32 is increased to open the relief valve 42 and the drain valve 50, oil flowing into the reservoir 44 is not reserved, but returned to the oil pan 18.

Filed: 1981-03-05
Abstract: PURPOSE:To prevent perfectly the disconnection of wirings by a method wherein poly Si is set on a field oxide film to form a thermal oxide film with a poly Si wiring superposed. CONSTITUTION:A poly Si 9 is formed on th field oxide film 2 of a P type Si substrate 1. An oxide film is formed on a gate oxide film 3 and the poly Si 9 by thermal oxidation, and a poly Si 4 is selectively superposed thereon. Next a gate oxide film is selectively opened to form an N<+> layer 5. Subsequently the substrate and poly Si are covered with an oxide film 6 by thermal oxidation with a layer insulating film 7 superposed thereon and opened to form a metal wiring 8. In this structure, when etched opening of a gate oxide film, the poly Si 4 is stripped off in the lower part. However, the etched parts of a gate electrode and poly Si layer on the field oxide film are perfectly filled, so that the formation of layer insulating films thereon produces no cracks without the disconnection of metal wirings.
