Title: Guide light
Inventor: OKAMURA SHINJI
IPC: F21V8/00
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To make the illumination light hard to leak from the outer peripheral end part of a light transmissive display plate by bringing a surface side vertical end part of the light transmissive display plate into contact with the vertical inside edge of an inner peripheral collar part, and bringing an inclined end part of the light transmissive display plate into contact with an inclined inside surface of the inner peripheral collar part. SOLUTION: In a light transmissive display plate 30, an inclined end part 36 comes into contact and engages with an inner peripheral collar part 16 of a frame body part 10a on its three sides, and the residual one edge engages with a light source housing part, and is fixed to a guide light main body 10 when the back face side comes into contact with a light guide plate 20. Even if the light transmissive display plate 30 is dislocated left and right or tries to go outside from an opening, since force trying to always return the light transmissive display plate 30 to a central side prescribed position of the opening acts by contact of an inclined face with an inclined end part 36 and an inclined inside surface 18, dislocation and a movement of the light transmissive display plate 30 can be prevented.  A clearance is hardly generated between the light transmssive display plate 30 and the guide light main body 10, and watertightness or airtightness is enhanced.

Title: Automatic transmission method
Inventor: ASAYAMA YOSHIO
IPC: F16D48/02
Filed: 1986-07-07
Abstract: PURPOSE:To prevent a creep and to reduce a shock at the starting, by increasing the clutch pressure at an oil pressure buildup rate prepared for the starting other than that at the speed change in a normal running. CONSTITUTION:The oil pressure buildup rate of the clutch pressure at the starting is stored preliminarily in a controller 30. And the first condition where the car is stopped or almost stopped, the second condition where the accelerator is ON, and the third condition where the brake is ON are detected respectively. When the three conditions are detected at a time, an electric command to make the clutch pressure in the starting speed phase zero is produced. After that, is produced an electric command to increase the clutch pressure at the memorized oil pressure buildup rate at the starting from zero, before at least either the first or the second condition is detected. Therefore, as well as a creep phenomenon is prevented by making the clutch pressure zero at the car stop, a clutch gear control with little starting shock can be realized at the starting.

Abstract: PURPOSE:To increase the mobility of carriers and accordingly to obtain the element of high Hall voltage by composing an insulating layer out of an SiO2 film when arranging a compound semiconductor layer on a magnetic substrate through the insulating layer to compose a Hall element. CONSTITUTION:A ferrite substrate 2 is spin-coated with an SiO2 group coat- forming applied solution in which a silicon compound is dissolved with an organic solvent, followed by sintering at temperature of several hundred degree to evaporate the solvent and to form a sintered SiO2 film 3 about 4,000Angstrom  thick on the substrate 2. Further on that, an InSb layer 4 is vapor-deposited to about 1mum thickness, followed by a heat treatment at about 500 deg.C to crystallize it. By photo-etching, the layer 4 is made into cross-form.

Abstract: PURPOSE:To prolong a fuel cell main body without a fall of an initial performance and complication of a cell structure by increasing the concentration of steam in reforming gas which enters into the fuel cell main body in the latter period of the operation of the fuel cell. CONSTITUTION:With the concentration of steam in reforming gas kept constant, the power generation performance of a fuel cell main body 6 rises gradually in the initial period of the operation, keep an approximately constant condition in the middle period and lowers gradually in the latter period. Therefore, in the latter period of the operation where the power generation performance lowers, the quantity of water which is dewatered from the reforming gas by a steam separator 3 is gradually reduced and the temperature of cooling mediam is controlled to gradually increase the concentration of steam in the reforming gas. Thereby, phosphoric acid which becomes insufficient is diluted so as to controll the quantity of slashed water. Owing to this constitution, lowering of the power generation performance is suppressed so that the service life of the fuel cell main body 6 is prolonged.

Abstract: PURPOSE:To enable recycling of polyester of a carpet base material by using polyester sheet for a packing material which backs a rear surfaces of the base material. CONSTITUTION:A polyester which can bond adhesive polyester to a carpet base material by thermal fusion-bonding is used as a packing material for a carpet. When they are adhered by thermal fusion-bonding, a heating temperature for causing the thermal fusion-bonding is a melting point of the polyester of the degree so as not to modify the carpet and the base material. Only adhering surfaces need a lower melting point than that of the carpet or the base material, and when the other surfaces are near the melting point of the carpet and the base material, a range of pressurizing condition may be increased in the case of the thermal fusion-bonding. Thus, a so-called a laminated structure in which the other surfaces are formed of the polyester having higher melting point than that of the polyester for forming the adhering surfaces is employed.
