Title: Method and device for controlling output of resistance welding machine
Inventor: TAKAGI SEIJI
IPC: B23K11/24
Filed: 1980-12-19
Abstract: PURPOSE: To make the quality of weld zones always homogeneous by detecting the voltage between electrode tips and perform circuit-like operations.  
     CONSTITUTION: Correct welding conditions are determined by preliminary experiment, and the outputs Vθ 1 WVθ 4  to angles of conductions θ 1 Wθ 4  are determined, and are programmed in an angle of conduction selecting circuit 13. Next, a new tip or a polished tip is employed and the output of the circuit 13 is set at Vθ 1 . The built-in counter of an alarm device 17 counting the change time of the Vθ 1 WVθ 4  is set zero and the count value emitting an alarm is set. The threshold value at which non-defective and defective of welding quality are made is determined and the output of a reference device 11 is so set as to attain the threshold value. After the above-mentioned setting is finished, the resistance welding is carried out successively. Until an alarm device 17 emits an alarm from one break point the welding is accomplished without dressing of the tip. After the alarm is emitted, the tip is dressed or exchanged.

Title: Semiconductor memory device
Inventor: MIHASHI JIYUNICHI
IPC: H01L21/822
Filed: 1980-12-18
Abstract: PURPOSE:To improve the integration density of a semiconductor memory by forming a convex projection or concave recess on a substrate and forming a conductor layer via an insulating film on the surface as a cell capacity, thereby increasing the charge storage capacity without increasing the cell area. CONSTITUTION:In a dynamic MOS memory, a P type substrate 1 is etched (or epitaxially grown) to selectively form a projection 1a (or recess 1b) in the substrate 1. This projection 1a is used as a cell capacity forming part, and a capacity gate electrode 5 is formed by an ordinary process via an oxidized film 4. When the height of the projection 1a is, for example, H, the capacity can be increased in the amount corresponding to 2H(L+W) with the same cell area, where W represents the width of the capacity, and L represents the length. Thus, the charge storage capacity can be increased with small occupying area, thereby enabling the increase in the density.

Title: Basket and handle thereof
Inventor: HAYASHI MASAAKI
IPC: B65D21/02
Filed: 1995-06-23
Abstract: PURPOSE: To dispense with a separate part in the mounting of the handle of a basket by using a thick wire material as each of the wire material of an opening edge and the wire materials reaching the opening edge from both sides of a bottom part and making the pitches of the wire materials of respective side surfaces on long and short sides different and bonding an auxiliary rod to the lower part of the short surface of the wire material of the opening edge or the lower part of the entire periphery thereof. CONSTITUTION: The handling part 15 of a handle 14 is downwardly fitted and attached to the outside of the constitutional frame 12 of a basket from the upper part of the basket. At this time, the fitting width 20 of the handle 14 is almost same to the outer diameter A of a main frame 10. The handle 14 is freely rotated after mounted but, when the handle 14 is rotated by about 90 deg., the constitutional frame 12 impinges against a support part 16 to stop the handle 14. The handling part 15 protrudes from the main frame 10 and is placed on the stepped part of a refrigerator to be used in a suspended state.  Since an auxiliary rod 13 is in contact with the lower part of the main frame 10 in such a state that the handle 14 is rotated by about 90 deg., the main frame 10 becomes thick by the outer diameter B of the auxiliary rod 13 with respect to the fitting width 20 and the handle 14 is not detached.

Filed: 1987-07-21
Abstract: PURPOSE:To produce single crystal ferrite contg. scarcely segregation in high yield by sealing single crystal ferrite contacting at a face with polycrystal ferrite in a deformable vessel, and transforming the whole to single crystals by pressurizing and heating externally. CONSTITUTION:In a deformable capsule A made of Pt, etc., constituted of a main body 10 of a cylindrical housing section having one side thereof reduced toward end and a cover section 11, a rod-like single crystal ferrite 13 is inserted to a bottomed cylindrical housing section 11c having a small inside diameter. Then, a single crystal ferrite 12 having a shape capable of being inserted into the capsule A is inserted so as to bring into contact with the single crystal ferrite 12 at a face. After covering the capsule with a cover 11, a flange 11c is welded to a cylindrical body 10a, and the capsule A is sealed by collapsing an evacuating pipe 11b while evacuating the capsule through the pipe 11b. The single crystal ferrite 13 is brought into pressurized contact with the polycrystal ferrite 12, and both are heat-treated by pressing the capsule A with a hot hydrostatic press. By this process, polycrystal ferrite 12 is transformed to single crystals in high yield using single crystal ferrite 13 as seed crystal.

Title: Treatment of exhaust matter produced during production of preform material for optical fiber
Inventor: KOIDE TOSHIO
IPC: G02B6/00
Filed: 1991-06-27
Abstract: PURPOSE:To shorten the time for stopping a production line by discharging the exhaust matter contg. fine glass particles formed in a reaction chamber by a discharge duct which is adjacent to the reaction chamber and is removably mounted to a fine glass particle removing chamber. CONSTITUTION:Glass raw materials, such as SiCl4, evaporated together with an oxygen hydrogen flame are blown from the side of a quartz rod 1 for a core within the reaction chamber 3 and the fine glass particles formed by a flame hydrolysis are deposited on the outer periphery of the quartz rod 1 for the core to form a porous base material 1a. The exhaust gases contg. the fine glass particles which do not stick to the rod at this time are discharged to the outside through the discharge duct 5 after the fine glass particles of large grain sizes are mainly removed in the fine glass particle removing chamber 4 which is adjacent to the reaction chamber 3 and is mounted removably from the reaction chamber 3. Since the greater part of the fine glass particles are removed in the fine glass particle removing chamber 4, the adhesion of the particles to the inside wall of the exhaust duct 5 decreases. Since cleaning frequencies decrease drastically, the time for stopping the production line can be drastically shortened.

Title: Motional principle of differential circulating current engine
Inventor: YONEDA SHIN
IPC: F03G7/00
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To make an input-saving circulating current engine compact and durable by selecting cylinder arrangement by which a difference between input pressure and output pressure is reduced, and generating circulating current motion by the use of a low differential pressure pump to be rotated under a condition where negative pressure is reduced in the pump. SOLUTION: An advancing valve 5 is turned on, and when an advancing pressurizing circuit 7 is pressurized, a propelling cylinder 14 and a delivery cylinder 16 are put under equal pressurization, and thrust in the thrust direction 21 at advancing time is generated. At the same time, a low differential pressure pump 12 is rotated, and the inside fluid of a delivery cylinder 17 is moved to the delivery cylinder 16. Therefore, a propelling shaft 18 makes rightward directional advancing motion. Since residual pressure is left in a retreating pressurizing circuit 8, it becomes differential motion overcoming inverse thrust of a propelling cylinder 15. The advancing valve 5 is turned off, and the propelling shaft 18 is made to perform leftward directional retreating motion, and input of the low differential pressure pump 12 becomes closed circuit input-saving motion.  In this way, a reciprocating motion cycle is continued, and circulating current motion is generated.
