Title: Carbureter air-fuel-ratio regulation
Inventor: KASHIWATANI MINEO
IPC: F02M7/24
Filed: 1977-12-20
Abstract: PURPOSE: A regulation system which operates with high performance for a long term by using a various air bleed valve including a diaphgram and a needle isolated from each other.  
     CONSTITUTION: A needle 33 isolated from a diaphgram 11 slides in a guide pipe 31 in which an orifice 34 is made. A valve 32 has the return spring 32 in contact with the bottom of the needle 33, which is put between the orifice 34 and the needle 33. A variable air bleed valve 30 is constituted as mentioned above. A concentric space is formed between the needle 33 and the open end of the orifice 34, resulting in a high performance regulation system. And the needle 33 comes in contact with one side of the orifice 34 to wear the part not the other part of the end face of the orifice 34, resulting in extended life of the system.

Title: Optical semiconductor ic
Inventor: MURAO FUMIHIDE
IPC: H01L27/15
Filed: 1988-06-21
Abstract: PURPOSE:To prevent coupling of signals from occurring between interconnections, by seperating and isolating a light-intercepting conductive film over desired interconnections for decreasing capacitance of the interconnections below the respective light-intercepting conductive films. CONSTITUTION:In an optical semiconductor IC, Al interconnections 2 formed on a substrate 5 are shielded from light by a light-intercepting Al layer 1 through an interlayer layer 4 so that among elements connected with the Al interconnections 2 those other than photodetectors are capable of performing circuit operation even under high illuminance. The light-intercepting Al layer 1 located over the Al interconnections to which signals not to be coupled are supplied is separated and isolated. In this manner, capacitance between the Al interconnections 2 below the divisions of the light-intercepting Al layer 1 can be decreased and coupling between those Al inter connections 2 can be prevented.
