Abstract: PURPOSE:To form a cuppy expanding section with a vertical end-surface wall by shaping the cuppy expanding section as a breaking section extending over a semicircular section through press machining and cutting the expanding section in the direction tying both end sections of the breaking section and in the direction vertical to a base section. CONSTITUTION:A cuppy expanding section 34, a center thereof swells conically, is formed by a formed feeding press mold. A breaking section and a thick section overlap within some extent in a boundary section between the breaking section (a) and the thick section (b) at that time. A stepped section 38 is shaped through press machining. The half of the cuppy expanding section 34 on the breaking section a side is removed through press cutting. Consequently, a half-cuppy expanding section 34a, is formed. A base section is machined to a shape, in which the upper surface of a blank 30 is required, by the press mold. The half-cuppy expanding section 34a is adjusted in thickness further required. Accordingly, the cut end surface of the half-cuppy expanding section 34a is expanded, and positioned. The central section (d) of an expanding end surface, a vertical end-surface wall, is cut and machined so as to be positioned at a desired position. Lastly, the base section 32 is trimmed from the blank 30, thus acquiring a heat sink for a semiconductor device.

Filed: 1990-02-15
Abstract: PURPOSE:To improve the convenience performance of a facsimile equipment by controlling the order of output of received data based on a specified caller number and outputting the received data corresponding to the specified caller number with priority. CONSTITUTION:A RAM 11 is provided with a work area used for an MPU 10 at its execution of processing and a table storing required information for control or the like. Key entry from an operation section 2 is detected via an operation section I/F control section 12 and when the entry designates a caller number, the caller number is successively received. The entered caller number and a caller number registered in a print queue table are collated and a reception text data to be outputted is read from a 'reception text storage address' area of the table in the case of awaiting the output and printed out. That is, the highest priority is placed at the printout according to the designated caller number and the text output relating to the caller number is implemented independently of the order of printout of the facsimile equipment. Thus, the convenience performance of the equipment is enhanced.

Title: Throw away tip
Inventor: FUKUOKA HITOSHI
IPC: B23B27/22
Filed: 1991-02-27
Abstract: PURPOSE:To improve chip discharging performance while preventing melting and chipping of a throw away tip which is formed of super high hardness sintered compact. CONSTITUTION:A cutting edge member 2 is brazed to the cutout 1a at the corner of a base metal 1. A super high hardness sintered compact 4 as the cutting edge member 2 is exposed to the upper face of the base metal 1 to form a tip breaker 5 on the surface. The grinding portion 5c of surface roughness 0.8S or less is formed on the cutting edge side of the tip breaker 5 and other portions than the grinding portion 5c have the surface roughness set to be more than 0.8S and 10.0S or less. The width (n) of the grinding portion 5c is 5% or more and 50% or less the width (m) of the tip breaker 5. Since the surface roughness of the grinding portion 5c is 0.8S or less, no welding or chipping occurs in a cutting edge E. Since the surface roughness of other portions than the grinding portion 5c is more than 0.8S, chippings are given sufficient slide resistance into curling form and still since it is limited within 10.0S, there is no degradation of chip discharging performance due to excessive cutting resistance.

Abstract: PURPOSE:To form a film of uniform thickness by removing excessive paint when the vapor of the solvent in paint is specific concn. or less. CONSTITUTION:In removing the excessive paint applied to a product to be coated by the natural flow down of paint, the amount of the vapor of the solvent allowed to be present in the atmosphere of a setting process is set a range from 0.1 times of the explosion lower limit value of the solvent to below the explosion lower limit value thereof. As the solvent contained in the paint, a thinner type, an ester type and an alcohol type are designated. The amount of the solvent in the atmosphere of the setting process is controlled by heating and evaporating the solvent so that the vapor concn. of the solvent in a hermetically closed container is held to a predetermined value. By this method, the irregularity of the capacity of the obtained film is reduced.

Abstract: PURPOSE:To cut off a sufficient air capacity with a simple structure by arranging fixedly a plurality of air inlet and outlet members selectively connected to an air delivering port member by the rotation of a male screw shaft and the operation of a solenoid in a box-like body. CONSTITUTION:A solenoid 4 having a female screw portion 5 is moved by the rotation of a male screw shaft 2 while being guided by guide rods 3, 3 and stopped in a position aligned with a desired air inlet and outlet member (for example 10).
