Title: Manufacture of semiconductor device
Inventor: SUZUKI KOHEI
IPC: H01L21/768
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To prevent the reduction of yield due to failure of wiring connection by heating a semiconductor device in a high-pressure gas atmosphere after a wiring step for all wiring layers and connection holes in a semiconductor device is completed. SOLUTION: First, a wafer which is finished as a semi-product through an LSI manufacturing step is tested. Next, a wafer producing a defective chip due to failure of wiring connection is annealed at a high pressure while being heated in a high-pressure gas, so that it is repaired. The causes of failure of wiring connection can be judged from the result of wafer test as follows: 1) a consumption current during operation is much smaller than the specified value; 2) no reaction with an input voltage is found in a specific signal wire; 3) no output voltage is produced in a specific output signal wire. Therefore, the defective wafer is annealed at 450 deg.C for 15 minutes and at 120MPa in an argon gas.

Title: Ventilator
Inventor: KOMATSU EISEI
IPC: E04B1/70
Filed: 1988-09-20
Abstract: PURPOSE:To introduce an adequate ventilating function in heating and cooling operation to a house at a low cost by a method wherein a hollow space is made inside a wall, two openings are furnished on the room side wall, one at a position higher than the middle of the wall and the other at the lower portion, and connected by one or more paths, and the outside wall is of an air permeable layer. CONSTITUTION:In heating operation, the air in a room is sucked into an upper opening 1 and discharged outside from an air permeable wall 3 through a duct 10 as shown by the arrows since the room temperature is higher than the outside temperature. The outside air is taken into the duct 10 through the air permeable wall 3 and flows into the room from a lower opening 2. Thus, the foul air is replaced with fresh air. A portion of warm air flows down through the duct 10 and returns into the room after mixing with the incoming outside air to mitigate the coolness of the outside air. Corresponding to this, a weak convection current is always produced in the room so that a very comfortable ventilation can be performed in the entire room without using a power. In cooling operation, the air current is reversed.

Title: Permanent magnet motor and linear type permanent magnet motor
Inventor: TSUMURA TOSHIHIRO
IPC: H02N11/00
Filed: 1987-09-19
Abstract: PURPOSE:To improve the efficiency of a motor by inserting a magnetic shield plate into a magnetic air gap only at the position where magnetic poles of both permanent magnets of a stator and a rotor are opposed to each other. CONSTITUTION:A magnetic shield plate 40 is rotated by a power transmission means 50 simultaneously with a rotor 30 so as to be inserted into an air gap g only when a stator permanent magnet 13 and a rotor permanent magnet 33 coincide with each other. When said rotor permanent magnet 33 approaches said stator permanent magnet 13, both permanent magnets 13, 33 repulse each other because they have the same polarity (N-N) so that a rotor 30 reduces its speed. However, because said magnetic shield plate 40 enters said air gap g in the direction of rotation of the rotor 30 so as not to be affected by a repulsive force due to the Meissner effect of the magnetic shield plate 40. Therefore, the rotor 30 continues its rotation in the direction of the arrow without reducing its speed.

CONSTITUTION:2 is the switching transistor and 3 is the bit wire to be formed of an aluminum electrode. 5 is formed on a part of an N<+>-type diffusion region 7 and an inversion layer 10, the inversion layer 10 is formed on an insulating layer 12 and the so-called (semiconductor on insulator) structure is formed. This structure can be obtained by the following method, for example, wherein the polycrystalline silicon film to be laminated on the insulating layer 12 is made to single-crystallize by performing an annealing. As the N<+>-type diffusion region to be formed on the SOI structure is diffused over up to the surface of the insulating film on the SOI structure is diffused over up to the surface of the insulating film on the SOI structure, no depletion layer does exist theoretically. Accordingly, the generation of depletion layers can be completely eliminated excluding some depletion layers to be formed in gate electrodes 1 and the N<+>-type diffusion region in the structure embodiment in this case against that depletion layers are sure to be inevitally formed in the drain of a conventional semiconductor memory element, wherein the SOI structure is not used. Hence, it follows that the soft error of the bit wire due to alpha rays cannot be theoretically generated at all.
