Title: Manufacture of semiconductor device
Inventor: NISHIMURA TADASHI
IPC: H01L29/786
Filed: 1988-10-12
Abstract: PURPOSE:To stabilize the characteristics of an element by separating the active layer of an element in an island state, performing isotropic etching, slightly etching an SiO2 layer which is in contact with the upper surface of the end part and the bottom surface of the island, oxidizing the exposed surface, and providing an oxide thick film at the corner of the active region. CONSTITUTION:An embedded SiO2 layer 14 and an Si layer 13 are provided on an Si substrate 10. A thermal oxide SiO2 layer 15 and Si3N4 layer 16 are overlapped. A resist mask 30 is provided, and RIE is performed. The embedded SiO2 layer 14 is selectively exposed. Then, the edge parts of the SiO2 layers 15a and 14 at the upper and lower sides of an Si layer 13a are etched away by isotropic etching using HF. A side oxide film 25 is formed in high temperature O2. Then, SiO2 or poly Si is deposited on the entire surface so that it is thicker than the Si layer 13a. The surface is flattened. Finally, with the Si3N4 layer 16 as an end point, etch back is performed. The SiO2, the poly Si or the like is made to remain between the active regions 13a, and an insulating and isolating region 26 is completed. In this constitution, the oxidizing conditions at the upper, bottom and side surfaces of the active region of the element become the same conditions. Strain does not occur, and the characteristics of the element are stabilized.

Title: Slot insulating film
Inventor: SATO MUNETADA
IPC: H02K15/10
Filed: 1990-09-26
Abstract: PURPOSE:To prevent an electrical insulating film which is inserted into a slot between core teeth from protruding into the slot by a method wherein cuff- shaped folded parts are formed on both the end parts of the inserting direction of the insulating film by ultrasonic welding. CONSTITUTION:A slot 8 in which a conductor is wound is formed between core teeth 4 and a slot insulating film 1 for insulation is inserted into the slot 8. The slot insulating film 1 is so formed as to cover the inner wall of the slot 8 and folded parts 2 are formed on the end parts of the inserting direction by ultrasonic welding. As the folded part 2 is formed by ultrasonic welding like this, the thickness of the folded part 2 is larger by the thickness of the insulating film toward the direction opposite to the slot and, even if the slot insulating film is inserted into the slot, a space for the conductor winding can be sufficiently maintained. Further, as the folded parts touch the core teeth, the position of the slot insulating film can securely be held and an insulation effect can well be exhibited.

Title: Device for supplying manual thread solder
Inventor: HIRAYAMA KAZUO
IPC: B23K3/06
Filed: 1991-07-04
Abstract: PURPOSE:To execute soldering with a fixed quantity in a suitable position without directly holding a thread solder with a hand at the time of soldering with the hand work in a supplying device for manual thread solder. CONSTITUTION:Feeding mechanism is constituted of a trigger 1 attached to a grip, a button 2 pushed in with the trigger, a leaf spring A 3 moving together with the button and claws attached to it. Then, the thread solder moving with the feeding mechanism is straightened by passing through the pipe 8. In the case of using the ordinary hand work soldering, since the thread solder is sent with fingers, lead component is stuck to the fingers and sometimes, the fingers are burnt by transmitting the heat at the time of soldering through the thread solder. This device solves the above-mentioned trouble and simultaneously by straightening the thread solder, the feeding to a fine soldering position can be accurately executed and further, the fixed quantity of solder can be fed. In such a manner, safety and reliability of the soldering can be improved.
Patent JP-H01101181-A (JP)
Title: Pressure sensitive recording medium
Inventor: OSANO NAGATO
IPC: B41J31/00
Filed: 1987-10-15
Abstract: PURPOSE:To prevent the deformation, deterioration and offset of an ink layer at high temperature and humidity, by a method wherein an ink layer contains polyamide resin of which acid value and amine value is under a given value, polyamide of which acid component uses hydro dimer acid, or polyamide resin containing dimer acid of more than specified amount as an acid component. CONSTITUTION:When an ink layer contains polyamide resin of which acid and amine values are not more than 0.5g KOH per gram, oxidization deterioration hardly occurs and the deterioration of ink layer is restricted. Carbon-carbon unsaturated bond, especially double bond contained in polyamide resin is susceptible to autoxidation and its tackiness increases by the generation of the functional group (e.g. aldehyde group) and breaking of a carbon chain. If a polyamide of which acid component uses hydro dimer acid is used, the ink layer is free from autoxidization. The presence of an acid component other than dimer acid, especially of monomer acid causes the deterioration of resin due to monomer acid acting as acid catalyst. Therefore, polyamide resin containing more than 95% of dimer acid as acid component will not cause deterioration.

Abstract: PURPOSE:To remove projections from a semiconductor substrate without damaging the surface of the substrate nor leaving pulverized pieces thereon by using a member whose flat surface touches and pulverizes the projections on the substrate carried by a rotating carriage. CONSTITUTION:A semiconductor substrate 1 is mounted on the upper surface of a carriage 3 in the state that a pulverizing member 4 is sufficiently separated above from the base 3, and the carriage 3 is rotated at a high speed. Then, the member 4 is moved downward by a supporting rod 5 to gradually pulverize a projection 2 on the substrate 1 rotating at a high speed together with the carriage 3 by an accurate flat surface 6 of the member 4. When the projection 2 is substantially pulverized, the rod 5 is stopped, the member 4 is moved upward by the rod 5, and the carriage 3 is stopped. Thus, the projection 2 on the substrate 1 is removed. The pulverized piece 7 of the projection 2 pulverized by the member 4 is scattered externally by a centrifugal force F at the moment in contact with the substrate 1, and removed from the substrate 1. Thus, it can prevent the substrate 1 from being damaged due to the pulverized piece 7 of the projection 2.
