Title: Manufacture of semiconductor device
Inventor: NAKAGAWA TSUTOMU
IPC: H01L21/60
Filed: 1984-12-10
Abstract: PURPOSE:To remove the outer peripheral part of a substrate simultaneously, in soldering the semiconductor substrate to a temperature compensating plate, by not soldering the peripheral part, which is to be removed in a later process in order to stabilize the surface, and only removing the peripheral base part close to the soldered part. CONSTITUTION:Soldering materials 3a and 3b comprising aluminum Al are separately attached to one main surface of a semiconductor substrate 1 and one main surface of a temperature compensating plate 2 except for the peripheral parts. Then, both soldering materials 3a and 3b are contacted and heated in a high vacuum state by a vacuum alloy method. Thus a soldered material 3 is obtained, and the semiconductor substrate 1 and the temperature compensating plate 2 are fixed. At this time, the peripheral part, to which the soldering materials 3a and 3b are not attached, is not fixed. Then, an electrode 4 is formed on the other main surface of the semiconductor substrate 1. Thereafter, sand is jetted from a nozzle 5 in the direction of arrows and broken lines. Thus the peripheral base part of the semiconductor substrate 2, which is not soldered 3 to the temperature compensating plate 2, is slowly removed from the surface.

Title: Disk cache control system
Inventor: HASHIBA ICHIRO
IPC: G06F12/08
Filed: 1988-10-19
Abstract: PURPOSE:To process a defective sector at a high speed by using a BB (battery back-up) RAM to secure area in the BBRAM for the defective sector and attaining the cache control even to a write request. CONSTITUTION:A control part 5 receives a data write request from a host computer 1 via a host interface 2 and retrieves a disk address storing part 6 of a BBRAM 3 to search an area where a flag is set at 1, 2 or 3 and the same time an address equal to that contained in the write request is stored. Then the part 5 replaces the data stored in an area corresponding to a data storing part 8 with the data contained in the write request. If the address is not searched, a flag storing part 7 is retrieved to search can area where the flag is set at 0 or 1. Thus the data required by the write request is written into an area corresponding to the part 8. Then the address of the written data is written into an area corresponding to the part 6. Then the flag is set at 2 and the end of a task is reported to the interface 2.

Title: Internal combustion engine
Inventor: YONEZAWA MINORU
IPC: B22C7/06
Filed: 1991-09-13
Abstract: PURPOSE:To provide an internal combustion engine where generation of casting deficiency can be prevented by efficiently venting gas in casting a cylinder head and removing sand after the casting. CONSTITUTION:In an internal combustion engine, a sand removing hole 17 bored in a cylinder head 1 is blocked by a plug 18, and a cylinder head seal surface (cover member) 1a for covering the upper portion of the sand removing hole 17 is formed integrally with the cylinder head 1. The sand removing hole 17 is inclined opposite to the cylinder head seal surface (cover member) 1a with respect to an axis L of a cylinder. When the sand removing hole 17 is inclined, an adequate diameter of the sand removing hole 17 can be secured without being limited by the cylinder head seal surface 1a. Consequently, gas venting can be sufficiently performed in casting the cylinder head 1, thus restraining generation of casting deficiency, and moreover, sand can be skillfully removed with high efficiency after the casting.

Abstract: PURPOSE:To epitaxially grow a single crystalline Si film on an exposed single crystalline Si substrate by vapor growth under reduced pressure at SiH4 gas partial pressure at a substrate temperature of a range of higher temperature from a predetermined boundary line by means of thermal decomposition of SiH4. CONSTITUTION:A reduced pressure vapor growth is conducted by means of thermal decomposition of SiH4 at a substrate temperature and SiH4 gas partial pressure of a range of higher temperature from a boundary line set at a line passing two points of a point of 20mTorr of SiH4 gas partial pressure at 890 deg.C of substrate temperature and a point of 20mTorr of SiH4 gas partial pressure at 950 deg.C of substrate temperature in which the substrate temperature is at an abscissa axis and the SiH4 gas partial pressure is at an ordinate axis. The substrate temperature and the SiH4 gas partial pressure are set in such a range. Thus, an Si film 8 is not grown on an insulating film 2, and a single crystalline Si film 3 is epitaxially grown only on the single crystalline Si substrate exposed through an opening 2a.

Abstract: PURPOSE:To reduce the particle diameter of a fluorescent material so as to enhance the emission efficiency of the fluorescent material by efficiently diffusing an activator in zinc sulfide in a short time at the same time as the sulfidization reaction of zinc oxide, and baking the zinc sulfide to form the fluorescent material. CONSTITUTION:After argon is substituted for air in a container hydrogen sulfide gas is passed through the container and zinc oxide to which the copper chrolide of copper haloganate is added and mixed in a predetermined ratio is heated at predetermined temperature and made to undergo a sulfidization reaction and then an activator is diffused in the zinc sulfide and the zinc sulfide is baked to form a fluorescent material and the fluorescent material is diffused in a predetermined solution and applied to a glass base on which a transparent electrode is formed, so as to form a luminescent layer. An insulating layer of a mixture having power of titanium oxide dispersed therein is formed and electrodes are deposited on the insulating layer to form an electroluminescent element. As the sulfidization reaction progresses, the activator is effectively diffused in the zinc sulfide in a short time. The fluorescent material is thereby generated with a small particle diameter so as to enhance the emission efficiency of the fluorescent material.

Title: Cylinder lock
Inventor: MAKINO TOSHIKAZU
IPC: E05B29/02
Filed: 1989-10-06
Abstract: PURPOSE:To prevent unlocking by unjust means by a method in which the projecting amount of a lock part is differentiated according to the height of a key corresponding to the contact part of a tumbler, and the contact faces of each key are allowed to align at the same levels regardless of the projecting amounts. CONSTITUTION:In a rotor 2, tumblers 13 are provided according to the height of the key top 6a corresponding to each contact part 13c, and according to the positions, the projecting amount A of the lock part 13b is differentiated. The lock parts of smaller projecting amount A are provided in high key hole 14 position, and also ones of greater projecting amount A are provided in low key hole position. When the lock parts 13b are projected, the contact faces 14a of each key are allowed to align at the same levels regardless of the projecting amounts A. In a state that the key is drawn out, the height of the tumbler 13 is read to make the production of master key impossible. The safety of the cylinder lock can thus be raised to prevent unlocking by unjust means.
