Title: Production of wear resistant composite casting
Inventor: MORICHIKA TOSHIAKI
IPC: C22C37/00
Filed: 1985-02-09
Abstract: PURPOSE:To obtain a crack-free and defectless casting having a two-layered structure by casting a secondary molten metal into the hollow hole of the hollow casting made of the W-contg. molten ferrous alloy having the two-layered structure formed under the effect of centrifugal force. CONSTITUTION:The molten ferrous alloy which consists of 1.5-5.0% C, <=3.5% Si and 25.0-80.0% W and is added with various elements according to purposes is cast into a preheated ceramic mold and is held still for a prescribed period, then a centrifugal rotating base 4 is rotated to form the hollow casting having the two-layered structure. The secondary molten metal is thereafter cast into the mold while the inside flank of the hollow casting maintains the temp. above the solidification completion point -100 deg.C to form a core material M2 welded to the casting to be made as the product. The oxidation of the inside surface of the casting is satisfactorily prevented if a flux is charged to the secondary molten metal prior to the casting thereof. The material M2 is removed by machining after the casting is taken out of the mold. The composite casing having the excellent quality is thus obtd. in the crack-free and defectless state.

Title: Radio line repeater
Inventor: SEKI NAOKI
IPC: H04B7/26
Filed: 1989-02-01
Abstract: PURPOSE:To realize special voice talking by incorporating the discrimination means discriminating whether or not a call is a test call in a function flow of a line repeater. CONSTITUTION:When a call is discriminated to be a usual voice talking not to be a test call through the discrimination processing, whether or not a system tone is superimposed on the voice signal is discriminated and when the tone is superimposed, relay operation is attained. The relay operation is continued by the discrimination processing till a talking timer expires. When no system tone is superimposed on the voice signal, the relay operation is terminated, a system tone interruption detecting timer is started and it is consecutive by the discrimination processing till the detection timer expires. In this case, even when the relay operation system tone is interrupted as to the test call, it is not terminated and it is consecutive till the talking timer expires. Thus, it is possible to attain the voice talking such tat e.g., a mobile equipment sends nothing but the talking subject to line relaying is not terminated.

Title: Semiconductor memory device
Inventor: KAGENISHI YUKIHIRO
IPC: H01L21/8242
Filed: 1985-02-12
Abstract: PURPOSE:To make it possible to implement high degree of integration and to secure the signal charge amount of a memory cell at the same time, by laminating a switching transistor on a plate electrode of an MOS capacitor, which is to become the memory capacitor of the memory cell. CONSTITUTION:A switching transistor is laminated and formed on the surface of a semiconductor layer 17 on the first electrode of an MOS capacitor. The semiconductor layer 17, on which the MOS capacitor is formed, is isolated from a substrate 11 by plate electrodes 14 and 23 and a columnar isolating region. Thus the memory cell capacity can be secured or increased without increasing the surface area of a memory cell. Since the semiconductor layer 17, on which the MOS capacitor of the memory cell is formed, is isolated by the cell plate electrodes and the columnar isolating region, the effect of charge generated in the substrate due to alpha rays is not applied to the accumulated charge in the memory cell.

Title: Thin film transistor
Inventor: OOTA MASAHIKO
IPC: H01L27/12
Filed: 1985-02-12
Abstract: PURPOSE:To obtain excellent ohmic contact between a channel region and an electrode region, by adding impurities to the electrode region in an adequate material, forming a TFT, and thereafter performing suitable heat treatment. CONSTITUTION:On an insulating substrate 1, a selectively formed gate region, a gate insulating film 3 thereon, a channel region 4 and an impurity added metal thin film 5 are deposited. After selective removal, suitable heat treatment is performed, and impurities are diffused to the channel region. Thus ohmic contact is obtained. In etching the metal thin film 5, a sufficient etching rate ratio between the film 5 and the channel region 4 can be applied. By this method, process difficulty due to forcible time control is alleviated. Since no restriction is applied to the thickness of the channel region, excellent condition for characteristics can be arbitrarily selected.
