Title: Crosslinking of crosslinkable polyethylene material
Inventor: TOSAKA AKINORI
IPC: C08J3/24
Filed: 1980-10-17
Abstract: PURPOSE: To obtain a high-gel content PE tape, sheet or block by efficient gelation, by heating and crosslinking an uncrosslinked PE material containing a crosslinking agent in an inert gas atmosphere at a specified pressure.  
     CONSTITUTION: For example, an uncrosslinked PE material containing a crosslink- ing agent, e.g., dicumyl peroxide, is processed into a sheet by extrusion at a temperature in the range in which the crosslinking reaction does not occur. This sheet material is wound around a core such as a metal pipe, together with a separator such as polyester. Wound around the outermost layer is a polyester tape or the like, and the roll is heated and crosslinked at 150W250°C for 30minW5hr in an inert gas (N 2 ) atmosphere at a pressure of 0W10kg/cm 2 . Then, the tape is cut to a predetermined width and length to obtain a crosslinked tape.  
     EFFECT: Gel fraction of at least 80% can be attained.

Abstract: PURPOSE:To contrive to improve the latch-up resistance of a CMOSIC by a method wherein the partial conductivity type of an epitaxial layer is inverted by diffusion of an impurity from a one-conductivity type substrate to the reverse conductivity type epitaxial layer thereon. CONSTITUTION:A P-layer 15 is provided by selective B diffusion to the P type Si substrate 1, and the N-epitaxial layer 16 is superposed, the B is diffused to the epitaxial layer 16 by the heat treatment at this time. A grown layer 2' atops in the state of nonreach to the surface of the epitaxial layer, the shape of the layer 2' being changed by being covered with an SiO2 film and then kept at a high temperature, the surface of the layer 16 being then etching-removed, resulting in the exposure of the surface of the layer 2'. Preferably, the profile of B concentration of the layer 2 is controlled by further theremal diffusion 17 of B from the surface of the epitaxial layer 16. This construction enables to set a well 2 at a high concentration, and then to suppress the potential variation of the well itself due to the parasitic current flowing in the neighborhood of the well bottom because of high concentration particularly there, accordingly the latch-up resistance of the CMOSIC further improved. Moreover, since epitaxial growth is used, there is the gettering effect to crystal strains, junction leakage reduces, and the yield improves.

IPC: H03K19/0175
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To provide an input-output driver circuit which has both a high voltage withstand property and extensibility and which needs only two power supply pins. SOLUTION: The power supply pins required for an input-output circuit are only two pins 38 and 42 while a high voltage withstand property and extensibility are achieved by providing a buffer interface between a functional digital circuit and a common bus for another digital circuit by using two PMOS switching transistors T1A and T1B instead of one PMOS switching transistor between the output line 30 of the circuit and an output power terminal 42. For turning off the transistors T1A and T1B, the voltage of an output power source 40 is applied to the gate of one transistor T1A or T1B and the voltage at the output line 30 is applied to the gate of the other transistor T1B or T1A.  Consequently, at least one of the transistors T1A and T1B can be surely turned off as required regardlessly whether or not the voltage at the output line 30 exceeds the voltage level at the output power terminal 42.

CONSTITUTION:A parts housing member at an uppermost stage stacked in pile by a vertical direction transferring device 4 is made to go up to a position till it reaches a locational position, while a holding member of a horizontal direction transferring device 6 is transferred to the lower part of a flange of the parts housing member at the uppermost stage and holding it thereat. And, the vertical direction transferring device 4 is made to go down for separation from the parts housing member at the uppermost stage, making it come into contact with the holding member, thus positioning in the vertical direction takes place. Also positioning takes place by pressing it to two reference planes by energization of both contacting and pushing devices being free of movement in the horizontal direction and installed in the horizontal direction transferring device. Therefore, the parts housing members stacked in pile can be individually separated and positioned, thus a function is made into compoundedness, while an equipment structure is simplifiable.
