Title: Semiconductor memory
Inventor: ABE KAZUHIKO
IPC: H01L21/8244
Filed: 1994-12-28
Abstract: PURPOSE: To improve element arrangement efficiency and to reduce a device area by using the element arrangement structure similar to element arrangement structure of a memory cell for the bit line potential compensation circuit of a static RAM having a memory cell where thin-film transistors(TFTs) is use as a load element. CONSTITUTION: The bit line potential compensation circuit is composed of a pair of the TFTs M1, M2. The element arrangement structure of the normal memory cell is used by connecting the drain electrodes via transmission transistors Q1, Q2 to bit lines B, -B and connecting the gate electrodes of Q1, Q2 to power source potential. The gate electrode of a first layer polycrystal silicon forming the gate electrode is formed on an element separating silicon oxidized film and is used as a wiring, by which the function of a driving transistor is eliminated. As a result, the arrangement of M1, M2 next to the normal memory cell is made possible and a function as a pseudo memory cell is used. The area of the device is drastically reduced by functioning these TFTs as the bit line potential compensation circuit having the element arrangement of the same area as the area of the memory cell.

Title: Fuel injection nozzle and manufacture therefor
Inventor: TSUKAHARA TAKAYUKI
IPC: B22F5/00
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To enhance fuel injection efficiency, and to easily manufacture a fuel injection nozzle by joining a nozzle tip member composed of an injection molding sintered body and a cylindrical nozzle body to introduce fuel to the nozzle tip member. SOLUTION: A fuel injection nozzle has a structure joined to a nozzle body being another member by forming a nozzle tip member 1 of an injection molding sintered body. In the tip member 1 of the fuel injection nozzle, an injection front chamber 4 to form an injection hole 3 becomes a valve seat. The tip member 1 is a part to control injection by abutting/separating a needle 5 to control injection. A reason of adopting an injection molding method for a nozzle tip part is that a cross section of a hole of the injection hole 3 can be made microscopic by exceeding a limit in machine work. Thus, fuel injection efficiency can be enhanced by the adoption of a joining structure and the adoption of the injection molding method.

Title: Semiconductor laser
Inventor: UNNO TSUNEHIRO
IPC: H01S5/00
Filed: 1987-12-25
Abstract: PURPOSE:To improve a semiconductor laser in property and manufacturing yield by a method wherein an epitaxial layer which is provided with a flat face and high in carrier concentration is used as a current constriction layer. CONSTITUTION:A semiconductor laser is composed of a P-type substrate 7 and an epitaxial layer highly doped with Sn used as a current constriction layer 6. The epitaxial layer using Sn as a dopant is hard to degrade the evenness of its superficial layer even if a large amount of dopant is used. Therefore, when an epitaxial layer highly doped with Sn is used as an n-type current constriction layer, the surface of the epitaxial layer is made flat notwithstanding that the layer is high in carrier concentration. By these processes, a semiconductor laser is decreased not only in a threshold current but also in the variability of property and improved in a manufacturing yield.
