Title: Method for restoring ductility of titanium or titanium alloy
Inventor: MAEDA HISASHI
IPC: C22F1/00
Filed: 1984-04-27
Abstract: PURPOSE:To restore the ductility of Ti or a Ti alloy having a surface layer embrittled by the absorption of hydrogen by annealing the Ti or Ti alloy by heating. CONSTITUTION:The concn. of hydrogen on the surface layer of Ti or the Ti alloy in seawater is increased by the absorption of hydrogen, but hydrogen is slightly absorbed in the inside at a certain distance from the surface, so hydrogen is distributed at different concns. in a part close to the surface and the central part. When the amount of hydrogen absorbed in the surface part exceeds about 200ppm, the ductility of the Ti or Ti alloy is reduced. A hydrogen thickened layer in the surface part can be diffused and vanished by annealing the Ti or Ti alloy by heating at 300-800 deg.C. By this method the ductility of the Ti or Ti alloy is restored.

Title: High molecular liquid crystal and liquid crystal element using the crystal
Inventor: KAWAKAMI YUSUKE
IPC: C09K19/34
Filed: 1993-04-12
Abstract: PURPOSE:To obtain a high molecular liq. crystal capable of highspeed response and which is easily formed into an element and to obtain a liq. crystal element from the crystal by linking a functional group having a hydrophilic group to the side chain of a polyoxetane principal chain. CONSTITUTION:The high molecular liq. crystal has a polyoxetane principal chain 1, and its side chain contains a functional group having a hydrophilic group 4. Meanwhile, a mixed film contg. a high molecular liq. crystal, a low molecular liq. crystal and an electrolyte is clamped by a couple of electrodes, at least one of which is transparent. Since a polyoxycetane principal chain 1 is used as the principal chain of the high molecular liq. crystal, the distance between the adjacent mesogen groups among the mesogen groups 3 (liq. crystal group) linked to the principal chain is increased, the interaction between the mesogen groups hindering orientation is reduced, and the mesogen groups are easily oriented when impressed with an AC electric field. Accordingly, the response to opacity to transparency in the element is speeded up.

Title: Printer
Inventor: OKUDA YUTAKA
IPC: B41J11/34
Filed: 1987-04-08
Abstract: PURPOSE:To reduce the size of a printer without causing breakdown of the door of a tractor, by constructing the printer such that lower end portion of door engages with a resilient projection of tractor body upon opening of the door. CONSTITUTION:Upon closure of a cover 4 with door 11 of a reactor 9 being opened (failure to close it in the direction of an arrow B), lower end of the cover 4 contacts the door 11. Here, pushing force of the upper cover 4 against the door 11 transmits from the lower end 11a of door to a projection 9a so as to deform the projection 9a resiliently thus disengaging the lower end 11a of door from the projection 9a and rotating the door 11 in the direction of an arrow C together with the upper cover 4. At this time, a sound is produced to alarm opening of the door 11. Consequently, the cover 4 is closed upon closure of the door 11. Since the door 11 is not broken down, the tractor 9 can be arranged near the cover 4 resulting in reduction of the size of a printer.

Abstract: PURPOSE: To obtain trioxan economically by a simple device wherein an aqueous solution of formaldehyde is heated, evolved vapor containing trioxan useful as a raw material for a resin is brought into contact with a solvent by a distillation column, and water is removed by azeotropic phenomena.  
     CONSTITUTION: An aqueous solution of formaldehyde is fed from the flow path 2 to the reactor 1, and heated in the presence of an acid catalyst. The evolved vapor is sent to the bottom of the distillation column 4, a water-insoluble solvent having a boiling point of 30W110°C is fed from the flow path 8 to the top  of the column, and they are brought into contact in a vapor-liquid phase. Azeotropic vapor of the solvent, form-aldehyde, and water distillating away from the  top of the column is cooled, condensed, and subjected to layer separation by the  separator 11. The water layer is taken out to the outside of the system, and the  oil layer is refluxed through the flow paths 12 and 8 to the top of the column. A solution of trioxan in the solvent is taken out from the middle part of the distillation column 4, and passed through the separator 7 and the rectifying column 19, to give purified trioxan. Characteristically only one distillation column is required and the amount of steam consumption is small.

IPC: B01D1/00
Filed: 1979-07-04
Abstract: PURPOSE: To stabilize the operation of a refrigerating unit which is used for a vacuum freezing drier or the like to cool a trap, without an excessive refrigerating equipment and energy consumption, by providing such a three-medium heat exchange mechanism that a coolant and a heat medium liquid circulate inside.  
     CONSTITUTION: A coolant pipe 26 is located in tight contact with the trap (steam condensation plate) 103 by welding, pressure welding or the like. The condensation plate 103 serves as a heat transfer fin for a coolant R. Heat is exchanged between the coolant R and a heat medium liquid B through the wall of the coolant pipe and the trap 103 which acts as the fin. Heat is exchanged between the heat medium liquid B and steam V through the trap (plate) 103 which acts as a heat medium liquid wall. Heat is exchanged between the coolant R and the steam V through the trap (plate) 103 which serves as the fin of the coolant pipe 26. The heat exchange between any two of the three media R, B, V is thus caused through a boundary metal wall or the fin plate.

Title: Method of covering with cylindrical heat-shrinkable film

IPC: B29C63/42
Filed: 1981-06-03
Abstract: PURPOSE:To cover without confinement of air, by joining a tube seat which has openings and whose lower outer diameter is smaller than the outer diameter of a base body to the upper end of the cylindrical base body with part of the tube seat lower section being exposed, putting a cylindrical heat-shrinkable film on the base body and the tube seat, and allowing the heat-shrinkable film to shrink. CONSTITUTION:The base body 1 is joined to the tube seat 3. The outer diameter of the lower section of the tube seat 3 is smaller than the outer diameter of the base body 1. Since the lower section of the tube seat has the openings 2, the air that has been expelled between the base body and the heat-shrinkable film will be discharged through these openings. The heat-shrinkable film 4 is heated to shrink with it being put over the base body 1 and the tube seat 3. Accordingly, covering can be effected wherein air would not be confined between the base body and the heat-shrinkable film.
