Title: Mold joint construction for cable
Inventor: ISAKA MUNEHARU
IPC: H02G1/14
Filed: 1988-02-04
Abstract: PURPOSE:To suppress the generation of voids and improve insulating characteristic, by stepped-stripping off the connecting end of a power cable to expose the core for connection, and by discharging air to introduce inert gas and to perform resin-molding. CONSTITUTION:The covering section 2 of the connecting end section 1 of a CV cable to be connected to is stepped-stripped off for connection and is penciling-processed, and a conductor is connected with a pressure-fitting sleeve. After that, the connected section is wound up with a semiconductive tape 3, and after it is heat-fused, it is set in an extrusion-molding metallic mold and is vacuum-led, and nitrogen gas is permitted to flow in. Then, resin is extruded into the metallic mold. After that, the connected section is taken out of the metallic mold, and the joint section is shaped and is covered with a semiconductive tube and is thermally shrunk to form an external semiconductive layer. The molding metallic mold is set again with the connected section, and the section is heated and is pressure-applied with the nitrogen gas and is fusion- molded. As a result, the generation of micro-voids at investigated points A-F is suppressed, and insulating characteristic is improved.

Title: Electrophotographic sensitive body
Inventor: IKESUE TATSUYA
IPC: G03G5/082
Filed: 1986-02-06
Abstract: PURPOSE:To obtain an electrophotographic sensitive body having high electrifiability, low residual potential, and high resistance to environmental influence by forming a barrier layer of a laminated body consisting of a first layer comprising amorphous boron nitride and a second layer comprising microcrystalline silicon, in addition to a surface layer formed of amorphous boron nitride. CONSTITUTION:A barrier layer of an electrophotographic sensitive body is constituted of a first layer 22 consisting primarily of amorphous boron nitride (a-BN) and a second layer 23 laminated thereon consisting primarily of microcrystalline silicon (muc-Si). Therefore, the electrophotographic sensitive body has high blocking effect. Particularly, if a-BN is arranged to the electroconductive substrate side, the adhesion to the substrate is improved. Further, since the second layer 23 of the barrier layer is formed of muc-Si having high sensitivity for long wavelength light as well as for visible rays, the light which has not been absorbed by the photoconductive layer 24 but transmitted therethrough is absorbed by the second layer 23 of the barrier layer. Accordingly, generation of interference fringes is inhibited.

Title: Digital-analog converter
Inventor: ISHII SATORU
IPC: H03M1/68
Filed: 1986-02-06
Abstract: PURPOSE:To decrease the conversion error by using a D/A converter capable of processing a data having a larger bit number (N+M) than a data bit number N and inputting a high-order bit data to a low-order M-bit of the D/A converter properly. CONSTITUTION:In selecting a position (a) for a switch S11 in case a current source of 2N<-1>I corresponding to the MSB has a positive error of nearly I/2, since the error is cancelled by the current source 2<-1>I, the conversion error is decreased. In turning the switch S11 to the position (b) in case the current source 2N<-1>I has a negative error of nearly I/2 conversely. In case the error of the current source 2N<-1>I is small, the switch S11 is turned to the position (c). When the error is an intermediate error between them above, the position offering a minimum error at the D/A converter output is to be selected depending on the degree of the error. Through the method above, the conversion error of the D/A converter is suppressed.

Title: Semiconductor integrated circuit
Inventor: ASAKURA YOSHITOMO
IPC: H01L27/10
Filed: 1985-02-12
Abstract: PURPOSE:To form an effective checking element of a part wherein the relative accuracy of each process poses problems, by changing the width of an ion implanting region to the channel region of a transistor along the longitudinal direction of the channel. CONSTITUTION:In a checking element, which is simultaneously formed together with a memory element, an area, where a gate electrode 1 of the checking element and ion implanting regions 2a and 2b are overlapped, is changed. This is caused by relative position relationship, which is a problem of poor ion implantation region in the capacitor part of a capacitor-part counter electrode 11 of the memory element. Therefore the effective channel width is changed. By measuring a channel current, correlation with respect to the relative position relationship is obtained. Thus defects due to relative errors in a plurality of processes including alignining and etching accuracy, whose clarification has been difficult, can be checked simply. Feedback to the manufacturing processes can be quickly performed, and extensive contribution to the stability of yield rates can be accomplished.

Filed: 1995-01-19
Abstract: PURPOSE: To prevent the gate electrode and the source-drain region from being superposed in the vertical direction by etching a semiconductor layer, containing impurities and overlying the gate electrode, wider than the gate length. CONSTITUTION: A semiconductor layer 18, containing impurities and overlying a gate electrode 12, is etched entirely and then further etched over a wider area.
