Title: Formation method of electrode for piezoelectric element
Inventor: TSUCHIYA JIRO
IPC: H01L41/09
Filed: 1990-11-26
Abstract: PURPOSE:To form electrodes uniformly up to the end part of a piezoelectric element and to obtain the electrodes on the surface of the piezoelectric element without exerting a thermal load by a method wherein the electrodes are formed on both the surface and the rear of the piezoelectric element and resist-plated films for the piezoelectric element on which the electrodes have been formed are removed. CONSTITUTION:A laminated pair 6 on which plated resist films 2 have been formed is separated into individual piezoelectric elements 1. The contamination on the surface to be plated is cleaned by a neutral detergent. Then, an electroless plating operation is executed; electroless plated layers 3 in a thickness of 1 to 2mum are formed on both the surface and the rear; an electrolytic silver plating operation is executed by using the plated layers as electrodes in order to lower the electric resistance of the electroless plated layers 3; electrolytic silver- plated layers 4 are formed. Then, each piezoelectric element 1 on which the electrolytic silver-plated layers 4 have been formed is immersed in an aqueous solution of sodium hydroxide; the plated resist films 2 on side faces are stripped and removed; electrode layers which are composed of the electroless plated layers 3 and the electrolytic silver-plated layers 4 are formed on both surfaces of the piezoelectric element. Thereby, the electrode layers can be formed uniformly up to the end face of the piezoelectric element, and it is possible to form the piezoelectric element which can be handled easily and which is not deformed thermally.

Title: Drive control device of elevating body
Inventor: GOTO YUKIO
IPC: E04H6/18
Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To prevent an elevating body from swaying by use of a simple constitution. SOLUTION: Pallets 27 with pierced holes are provided to be vertically movable in lifters 17 of a multi-story parking lot 11. When the pallets are vertically transferred, an optical axis formed by a light-emitting element 14a and a light- receiving element 14b penetrates the pierced hole. When a vertically moving pallet 27 sways, the optical axis is blocked by the pallet 27 and the light- receiving element 14b outputs off-signals to a controller C. The controller stops the lifting motor of the lifter 17 holding the pallet 27 on the basis of the off- signal from the light-receiving element 14b to stop the pallet 27. The pallet 27 brough to a stop ceases to sway gradually.

IPC: F25B29/00
Filed: 1993-11-29
Abstract: PURPOSE: To provide a method and an apparatus for controlling the temperature of air-conditioned space to the specified temperature, utilizing the supply source of cryogen. CONSTITUTION: A cryogen is drawn out of the supply source within a flow path 42 and produces a cooling mode through a heat exchanger 46 provided within the flow path. A vapor drive motor 78 arranged within the flow path in the downstream of the heat exchanger drives a fan 76, whereby it moves air between the air conditioning space and the heat exchanger. After all cooling modes are performed, heat 90 is applied in the downstream of the heat exchanger to the cryogen so as to produce desired fan horse power without hindering the cooling cycle. A bypass flow path 124 selectively sends a cryogen directly to a vapor drive motor and bypasses the heat exchanger, whereby it performs air circulation within the air conditioning space in case that the temperature of the air-conditioned space is satisfactory.

Title: Processing method referred to welding ring production
Inventor: KADOTA KAZUHISA
IPC: B24B9/04
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To resolve such a problem referred to a production of a welding ring that when processing of unsealed rings before welding, a process flow becomes necessary to separate an abutted face of the cut end part being parallely overlapped for making them in elliptical unsealed rings, and also a problem that a set-up change becomes necessary or unnecessary under-cut accrues when deburring work takes place after the welding is over. SOLUTION: A linear material is formed into a circular ring element C by fitting to coiling tools 13A-13D. Then a linear material longer than a circular length of the ring is fit to the coiling tools for forming a new circular ring element C, so that an elliptical un-sealed ring M is formed by cutting a boundary part of the two ring-like elements while a front end of the curved wire material of the circular element formed first is abutting to a movable cutting tool 16. Also, a welding part is positioned at a given reciprocation shaft line 47, and the welding part Po is ground by reciprocating the welding ring P with a burr, while it is abutted to the grind stone 41. A non-burring welding ring R is thus formed by deleting the welding burr Pb.

Title: Epoxy resin composition
Inventor: MORINAGA KUNIHIRO
IPC: C08G59/30
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To obtain a resin composition having a good compatibility with a high-molecular weight or flame-retardant resin and a good storage stability by mixing a bisphenol epoxy resin having lower acyl groups as side chains with an organic solvent having a specified solubility parameter. SOLUTION: The bisphenol derived epoxy resin used is one having 1-3C acryl groups as side chains. It is exemplified by one having 2-acryl-1,3-propylene glycoxy groups in place of the 2-hydroxy-1,3-propylene glycoxy group formed in the oligomeration by reacting an epoxy resin with a polyhydric phenol. When the bisphenol type epoxy resin has a high molecular weight, it shows poor solvent solubility and poor storage stability in the form of a varnish, whereas the halogenated bisphenol epoxy resin, even if it has a low molecular weight, shows poor solvent solubility. They, however, can be improved by the introduction of acyl groups thereinto. The solubility parameter of the organic solvent is 7.0-13.0. This is a countermeasure for the introduction of acyl groups.
