Title: Method for testing durability of heat-fixing roller
Inventor: KON SHUJI
IPC: F16C13/00
Filed: 1986-12-12
Abstract: PURPOSE:To obtain a durability testing method reduced in time and cost in stead of a real machine durability test by immersing heat-fixing roller in boiled water for a prescribed time, drying said roller, heating it up to a heat-fixing temperature, and checking the presence of a film floating phenomenon from the lower layer of fluoroplastics. CONSTITUTION:In case of testing the durability of a heat-fixing roller obtained by tightly coating the shaft of the roller with fluoroplastics directly or through a rubber layer, the roller 1 is immersed into boiled water 2, and after the passage of several hours, pulled up, dried to remove after adhering water sufficiently. Then a heater is inserted into the shaft of the roller 1, power is supplied to the heater and the surface temperature of the roller 1 is heated up to 200 deg.C to check the presence of the film floating of fluoroplastics. When the result of the heat-fixing roller durability test is compared with that of a durability test using a real machine, excellent coincidence can be obtained.

Title: Radio equipment for relay
Inventor: ITO TOSHIAKI
IPC: H04B1/04
Filed: 1990-11-02
Abstract: PURPOSE:To prevent missing of a data by storing tentatively a reception data signal and outputting the reception data signal to a transmission section as a transmission data signal after the transmission output reaches a prescribed operating level. CONSTITUTION:When a reception level exceeds a prescribed squelch level, a reception section 2 brings a squelch signal S2 to be outputted to a transmission section 3 to an H level to start a power amplifier transistor(TR) of the transmission section 3. Moreover, the reception section 2 outputs a reception data signal S1 to a memory section 5 and the memory section 5 stores tentatively a reception data signal S1. A transmission output monitor section 6 monitors a level of a transmission output S3 of the transmission section 3 and outputs a data transmission control signal S4 indicating it that the reception data signal S1 stored in advance is outputted as a transmission data signal S5 when the transmission output S3 exceeds a preset threshold level based on the operating level of the transmission section 3 to the memory section 5.

Title: Automatic setting reducing valve
Inventor: KOIKE TADASHI
IPC: G05D16/16
Filed: 1989-11-15
Abstract: PURPOSE:To increase the volume of passing fluid at the time of initially rising steam by throttling a pressure control means to set a reducing valve at high pressure level after detecting the satisfactory reduction of the primary pressure. CONSTITUTION:The primary pressure is reduced when the operation of a boiler is stopped after the end of a job. A detector 31 detects the reduced primary pressure, and a motor 19 is driven to move down a pressure control screw 18 when the primary pressure is set at a prescribed level. Then a pressure setting spring 14 is compressed and a pilot valve 9 is fully opened. Under such conditions, the edge of a program used for the normal pressure control is cut. If the operation of the boiler is restarted on the next day, for example, the rising primary steam pressure owing to the full open of the valve 9 is used to the full. Thus a piston 8 is moved down to press down a main valve 7. As a result, a valve port 6 is fully opened. In such a constitution, the volume of passing steam is increased more at an early stage of rise.

Title: Stage apparatus
Inventor: TSUI KOTARO
IPC: B23Q1/62
Filed: 1996-10-22
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a natural vibration associated with a surface plate, by providing a first mobile body moving in a first direction and a second mobile body moving in a second direction orthogonal to the first direction on the reference surface of the surface plate, and by supporting the first mobile body in the second direction via a force compensating element. SOLUTION: Along a fixed guide 3 of a surface plate 1, an Y stage 4 moves in an Y direction in a non-contact way. To the Y stage 4, an X stage 10 for holding a wafer 12 moves in an X direction in a non-contact way. Right and left linear motors 7 are coupled to the Y stage 4 and an X linear motor 6 is coupled to the X stage 10. By a similar method to the linear motors, a force compensating element 100 generates a compensating force between a base and the Y stage 4 in the X direction in a non-contact way. When driving the X stage 10 in the X plus direction, the driving force generated from the X linear motor 6 so operates in the X direction that its reaction force acts on the Y stage 4 in the X minus direction.  The force compensating element 100 generates from a frame to the Y stage 4 a compensating force having the same magnitude as the reactive force and operating in the X plus direction to cancel the reaction force.

Abstract: PURPOSE:To provide the above fibrous laminated body, which is used in wide field by utilizing its excellent fire resistance, heat insulating properties, sound insulating properties, vibration insulating properties, flexibility, softening properties, compressibility and the like. CONSTITUTION:When inorganic fibers compounded with fibrous binder is heat- treated, the fibrous binder condenses at parts, at which inorganic fibers intertwine with each other so as to form united points 2. Since the united points 2 uniformly distribute over the whole inorganic fibers 1, no local shortage of strength develops in the integrated fiber layer 3, resulting in forming layer excellent in stability in quality. Onto one side of both the sides of the fiber layer 3, self-adhesive layer 4 and release paper 5 are laminated. Thus, since the amount of distribution of the united points 2 can be arbitrarily changed in response to the amount of the fibrous binder compounded with the inorganic fibers 1, a product having the strength corresponding to the required characteristics can be obtained. The obtained fibrous laminated body is cut to the predetermined size with scissors or the like and, after the release paper 5 is peeled off, pasted to the surface of an object.

Title: Thermal recording device
Inventor: KATO MUNEHISA
IPC: B41J2/38
Filed: 1987-11-26
Abstract: PURPOSE:To shorten a warming-up time upto a normal operating state and eliminate a density unevenness in a linear direction by driving for instance, two heater systems simultaneously or driving a heater with a larger heat generating ability during a warming-up operation, and selecting the blowing direction of an air blower each time a fixed temperature is reached. CONSTITUTION:A warming-up time is shortened by driving two heater systems 6a, 6b in a larger heat generating state during a warming-up operation than during a normal operation. After the warming-up operation, the ambient temperature of a thermal head is kept at near a set temperature T2 by controlling the switching ON/OFF of the heater 6b with the set temperature used as a target temperature. In the meantime, a temperature controller drives blower fans 8a, 8b to a normal rotating direction. Consequently, an atmospheric air is taken into a heat sink 7 from an direction A, and when the temperature becomes lower than Ta, the temperature controll stops driving the blower fans 8a, 8b. When the ambient temperature of the thermal head exceeds T2 again, the temperature controller drives the blower fans 8a, 8b to a rotating direction. Consequently, an atmospheric air is introduced into the heat sink 7 from a direction B.
