Title: Drill for machining
Inventor: YANO TADAAKI
IPC: B23B51/02
Filed: 1986-04-09
Abstract: PURPOSE:To prevent breakage of a cutting tip during machining through strengthening of the bond by furnishing a recess at the foremost end of a drill body, providing a projection at the cutting tip and brazing the recess to the projection so as to form a consolidated construction. CONSTITUTION:A recess 14 with channel-shaped profile is furnished at the foremost end-face 13 of a drill body 11. The cutting tip 15 is formed from extra-hard alloy or ceramic, wherein the outside dia. shall be the same as the drill body 11. A projection 17 to detain with said recess 14 is formed at the base end-face 16 and brazed solidly using a brazing material 18 in the condition that the recess 14 is in detention with the projection 17. A spiral cutting edge 19 is formed continuously at the outside surface of the drill body 11 and the cutting tip 15. Because the drill is in mechanically locked condition even though torsional strength is applied during machining, the cutting tip 15 is free of risk of breakage, and the margin for re-machining is long to ensure better economy.

Title: Liquid crystal display device
Inventor: WAKEMOTO HIROBUMI
IPC: G02F1/1339
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To make it possible to drastically shorten a liquid crystal injection time and to improve the display grade of images by forming injection ports for vacuum injection of a liquid crystal compsn. between substrates on one side of two sides parallel with the scanning wirings of a sealing part enclosing the circumference of a screen having a rectangular shape. SOLUTION: The injection ports 2 for vacuum injection of the liquid crystal compsn. between the substrates are formed at two points on the one side of the two sides parallel with the scanning wiring direction 3 of the sealing 1 part enclosing the circumference of the screen having the rectangular shape. While the liquid crystal injection direction is heretofore in alignment to the long side direction (scanning wiring direction 3) of the screen, this direction is aligned to the short side direction (signal wiring direction 4) by adopting such constitution. In addition, the director direction of the liquid crystal molecules existing in the central part between the upper and lower substrate is aligned to the flow direction at the time of the liquid crystal injection, by which the viscosity is lowered.  As a result, the time for the liquid crystal injection is shortened and this constitution is effective at the time of an IPS(in-plane switching) mode.

Title: Image recording device
Inventor: KODAIRA HIDEKAZU
IPC: G03G15/00
Filed: 1991-04-15
Abstract: PURPOSE:To enable a satisfactory toner image to be formed despite the deflec tion of a main roller by curving a recording electrode into a raised form in paper feeding direction on a swirling side with respect to a device for transfer ring the toner image formed on the main roller to paper. CONSTITUTION:Since a main roller 1 and a pressing roller 2 in an image recording device are arranged intersecting each other at an angle of 1.47 deg. to spread out pressure uniformly therebetween, paper is moved obliquely when it is running between both the rollers 1 and 2 and the paper being fed in the direction of the arrow A is taken away in the direction of the arrow B. To accomplish this, a recording electrode 3 having a plurality of recording electrode needles arranged in a row in the surface of a base plate is formed horizontally with a slight curve in the rotating direction of the main roller 1 on the downstream side. The recording electrode 3 is arranged by making a straight line connecting both the ends of the base plate intersect the axis of the pressing roller 2 at an angle of 0.35 in the reverse direction. This permits a strain-free transferred image to be formed despite the oblique movement of the paper upon image transfer.

Title: Production of al series hot dipped steel plate excellent in heat resistance
Inventor: OKADA KOJI
IPC: C23C2/12
Filed: 1985-04-19
Abstract: PURPOSE:To obtain an Al series hot dipped steel plate excellent in the heat resistance by coating a soln. of a compd. contg. rare earth elements on the surface of the steel plate and thereafter performing the Al series hot dipping thereon. CONSTITUTION:After purifying the surface of a steel sheet plate, a soln. dispersed with a compd. of rare earth elements such as Y2O3 and CeCl3 is coated thereon. If necessary, the thermal diffusion treatment of the surface is performed. Thereafter the Al series hot dipping is performed by an ordinary method. In this hot dipped product, the composite action is caused by both rare earth elements such as Ce or Y and Al or Si incorporated in the hot dipped layer in a period of the heat resistant use and an inner oxidized layer of Al or Si formed in an interface of the alloy layer is made dense. Therefore the barrier action for the mass transfer between the film and the alloy layer is increased and thereby the oxidation velocity is decreased and also the peeling of the hot dipped film is suppressed by the wedging effect of the film. Also the mutual thermal diffusion of both Al incorporated in the film and Fe of the base metal is prevented and the heat resistance is inevitably improved.

Title: Rotary head assembly
Inventor: NAEMURA KOJI
IPC: G11B5/265
Filed: 1986-04-08
Abstract: PURPOSE:To eliminate the variation of the gap caused between head chips despite the fluctuation of fastening force by providing a relief part to the shim part set opposite at least to the vicinity the inner end part of a slit groove and therefore no contact is produced between a rotary drum and at least the bottom of said inner end part of the groove. CONSTITUTION:A relief part 14 is formed as an opening of a shim 12A and therefore the vicinity of the inner end part 13 of a slit groove 7 has no direct contact with the upper plane of a rotary drum 5. For the force lines produced within a head base 2 by the fastening load of a fixing screw 9 with a rotary head assembly, no stress is concentrated even at the part 13 owing to the part 14 formed to the shim 12A opposite to the vicinity of the part 13. As a result, no distortion is produced at the part 13 and therefore the groove 7 has no change of its own width. Thus the gap space (d) formed between head chips 3 and 4 produces no change either.

Abstract: PURPOSE:To select accurately and quickly articles of different weight by installing a suction pipe communicating with a suction pump on the upstream side of a wind channel pipe with a feed section of the article and forming a removal opening for parts dropping without being sucked to the lower end side of the wind channel pipe. CONSTITUTION:When a suction pump 3 is operated, wind is blasted in a wind channel pipe 2 at the given speed from below upward to generate a suction flow flowing from below upward. Out of water capsules fed successively from a feed section 1 into the wind channel pipe 2, the capsules lighter than the suction force are drawn from the upstream side of the wind channel pipe 2 into a suction pipe 4 and stored in a storage chamber 6. At that time, the operation of the suction pump 3 is adjusted in compliance with the output of a suction sensing means 5. On the other hand, capsules heavier than the suction force are not sucked and dropped through inside the wind channel pipe 2 by gravity and taken out of removal openings 7. The remaining time of water capsules in the wind channel pipe 2 is extended by blowing from below upward by a blower 8 to drop heavy capsules only in a more secured manner.
