IPC: H01L29/78
Filed: 1987-07-13
Abstract: PURPOSE:To minimize overlap capacitance sufficiently by forming s part wherein source and drain diffused layers as well as a gate electrode overlap one another with the exception of the part which is in contact with a channel with an insulating film which is thicker than a gate insulating film. CONSTITUTION:After forming source and drain diffused layers 2 and 3 through ion implantation by using materials holding enough shielding capacity for ion implantation as masks, in succession from the above formation, oxygen is ion- implanted in the surfaces of the diffused layers and these layers allow a gate insulating film 6 to grow after removing the above masks, and then a gate electrode 7 consisting of Al is formed. At a considerable part of areas overlapped between source and drain layers 2 and 3 as well as the gate film 6, insulating films 4 and 5 located at the sides of source and drain 2 and 3 which are sufficiently thicker than the gate insulating film 6 are formed by being sandwiched. Equivalent overlap capacitance can be decreased sufficiently so that its capacitance is equal to that of self-alignment type where an ordinary polysilicon gate is used.

Title: Radio selective calling system
Inventor: SHIMANUKI YOSHITARO
IPC: H04W36/36
Filed: 1988-07-15
Abstract: PURPOSE:To shorten a switching time by announcing the frequency of an adjacent area, storing the frequency in a receiver and switching a receiving frequency based on the frequency when the receiver is called from respective base stations, which uses different radio frequencies, in plural areas. CONSTITUTION:The receiver stores the frequency used in the adjacent area to a frequency storing part 7 in advance. When the receiver moves to the adjacent area and a receiving condition is degraded, only the frequency stored to the frequency storing part 7 is received out of the many setting frequencies of a frequency setting part 8. Then, only by investigating the receiving conditions of those frequencies, the frequency can be moved to the frequency of the adjacent area. Accordingly, the switching time of the receiving frequency can be widely shortened.

Abstract: PURPOSE:To contrive the improvement of reading accuracy by precisely correcting a mirror angle by the operation of an elastic material disposed on the end edge part of the mirror when the mirror appears at a prescribed position from a reserving position at the time of switching a reading direction. CONSTITUTION:At the time of reading from a flat bed reading unit 20, a mobile plate 40 is moved from the left end position right-ward, the engagement of the lower end part 42a of a mirror retaining plate 42 and an engaging protrusion which is not shown of the main body of the device is released and restored to a position shown by a full line by the operation of a coil spring 45. In such a case, the engagement relation of the mirror retaining plate 42 and a pin 44 is comparatively loose, so that the mirror 33 is evenly and correctly pushed to a butting part 46 by the coil spring 46 disposed on the end edge part. Accordingly, the position of the mirror 33 causes light beam from the lamp 38 of an upper part to guide to a reading part 24 correctly.

Title: Pilot operation oil pressure circuit of construction machine
Inventor: YASUDA TOMOHIKO
IPC: F15B21/04
Filed: 1993-07-15
Abstract: PURPOSE:To improve operbility, by automatically reducing the back pressure of a pilot valve when the hydraulic oil of pilot circuit is heated when its temperature is low. CONSTITUTION:When a differential pressure between a pressure acting on the port A of a opening/closing valve 22 and the pressure of a hydraulic oil tank 3 is higher than a preset pressure of the opening/closing valve, the ports A, B are closed. The discharge hydraulic oil of a pilot relief valve 7 passes through a pilot valve 8 and a lock valve 10 via a temperature rising valve 9 and enters in the hydraulic oil tank 3 to heat respective parts. When the viscosity of hydraulic oil gets low and a pressure difference between the tank 3 and the port A becomes low and it becomes lower than a present pressure of the opening/closing valve 22, the ports A, B are connected to each other. And the most of the hydraulic oil flows in the opening/closing valve 22 and a pressure loss between the temperature rising valve 9 and a full flow filter 11 becomes almost null. And further, the inside pressure of the temperature rising valve 9 gets low and the flow rate of hydraulic oil flowing in the hydraulic oil tank 3 through the port T of the pilot valve 8 becomes low. In this way, the back pressure acting on the pilot valve 8 can be reduced and the operating power therefor can be reduced.

Abstract: PURPOSE:To hinder header processing from causing the solder reaching the surface of the contact by forming a conical step at the periphery of the joint surface of a contact chip for jointing with a columnar base with the central part left, brazing the contact chip fast to the columnar base, and performing header processing. CONSTITUTION:With the central part 2a left, a conical step 2b is formed at the periphery of the joint surface of a contact chip 2 to provide a contact chip 2'. This contact chip 2' is brazed fast to a columnar base 3 with Ag solder 4 to provide a clad contact material 5'. This clad contact material 5' is header processed to provide a rivet type contact 6'. At this rivet type contact 6', molten solder 4' stagnates in a ring-shaped recess 7 between the conical step 2b of the contact chip 2' and the joint surface of the columnar base 3 when the contact chip 2' is brazed fast to the columnar base 3, and does not float up to the periphery of the contact chip 2', and thus the header processing does not cause the solder 4' reaching the surface of the contact.
