Filed: 1991-05-14
Abstract: PURPOSE:To improve working efficiency by adhering a water absorbing fiber sheet, on the surface of which a light-weight bone material or a builder for retarding coagulation is applied, to a construction joint surface, and by joint constructing concrete after the sheet is peeled off. CONSTITUTION:A light-weight bone material 3 and a mixed chemical 4 of a builder for retarding concrete coagulation and a bonding agent, are applied on the surface of a water-absorbing fiber sheet main body 2, so as to form a sheet 1 for construction joint. The sheet is adhered to a construction joint surface so that the light-weight bone material is in contact with the surface, and a roughness is formed on the surface, while a mud component floated on the surface is absorbed thereby. Before construction joint concrete is cast, the sheet 1 is peeled off, and then the concrete is cast. The bonding intensity is increased, while the working efficiency is improved.

Filed: 1995-05-11
Abstract: PURPOSE: To polish a narrow surface by utilizing intermittent flow or continuous flow of fluid whose flow rate is variable as a drive means for vibrating brick. CONSTITUTION: Operating fluid such as water is poured into a rotary drive shaft R from a fluid source A to fill a flexible jack 6 with it so as to generate a rise for causing expansion and shrinkage movement of the flexible jack 6. This rise causes a vibration disc 10 and a finger 11 to move in the direction of axial line, and return due to elastic force is ensured by an elastic receive part 14 when the finger 11 comes into contact with a bottom face of a hold part 12 to apply vibration action on a bottom plate in the hold part 12. As an example, it is possible to cause the vibration of about 50 times per minute in the hold part 12 and a brick 16 by a fluid supply source A generating a flow rate of 6 liters per minute at relative supply pressure of 4 bars.  These results are obtained when a gradual advance elastic member having Shore A hardness of about 55 degrees is used as the elastic receive part 14.

Title: Fixing device and image forming device
Inventor: YAMAZAKI MICHIHITO
IPC: G03G15/20
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To reduce curl generated in a recording paper at the time of fixing/ ejecting it, to eliminate a stop for removing a curled paper and to speedily execute automatic both-face printing by adopting such a constitution that the longitudinal end face, especially the longitudinal end face on the downstream side in the carrying direction of the recording paper, of a ceramic heater is located in a fixing nip. SOLUTION: The longitudinal end face of a heating body is arranged in a fixing nip width formed between the heating body and a pressure means by its elastic deformation. For instance, in a film heating/fixing device, a heater unit 90 consists of a heater 80, a film guide used also as a heater holder 86, a reinforced metal plate 87 and a fixing film 88. Then, it is constituted so that the longitudinal end face, especially the longitudinal end face on the downstream side in the carrying direction of the recording paper, of the heater 80 is located in the fixing nip. Thus, the direction of ejecting the recording paper 40 just after fixation can be brought close to the extension of the fixing nip and the curl generated in the recording paper 40 is reduced to make the applicable region of the fixing temperature wide.

Abstract: PURPOSE:To prevent an engine from damaging, by providing a device controlling generation of surging at the time of decision of a disorder by a surge detector, in a device making closed loop control so as to coincide the speed of a gas generator with a given target speed. CONSTITUTION:The titled controller computes a fuel supply quantity by making the quantity correspond to a target speed based on the output of an accelerator opening sensor 17 interlocking with an accelerator pedal in a control part 11 and controls a fuel supply device 8 to a combustor 7 according to the computed value of the control part 11. Feed back control is done so that an actual speed to be detected by a speed detector 13 of a gas generator coincides with the target speed. In this instance, the above target speed is corrected so as to avoid surging based on the output of a surging sensor 16 provided on a compressor 1 and surging is inhibited constantly from generating when a disorder of the sensor 16 is detected, for example, by controlling acceleration of a gas generator at a value less than a given one.

Title: Lamp controller
Inventor: JIYON EMU UON
IPC: H05B41/392
Filed: 1990-05-28
Abstract: PURPOSE: To control lamp voltage by applying a voltage lower than that applied during ignition to the filaments of a fluorescent lamp at an initial preheating stage, increasing the voltage gradually to high voltage values unit the lamp is ignited, and lowering the voltage in response to an increased load after the lamp is ignited. CONSTITUTION: During the initial energization and operation of a controller 10, an operating voltage is supplied to a control circuit 36 from a power circuit 40 via a line 39. A voltage generated at a start line 44 does not apply a sufficiently great voltage to ignite lamps in a preheating stage, but supplies a high frequency current to the filaments of the lamps 11, 12. In a subsequent ignition stage, the lamp voltage increases gradually to a high voltage value until the lamps are ignited, and, when the lamps 11, 12 are ignited, the lamp voltage decreases in response to increased load due to the conduction of the lamps. Therefore, a fluorescent lamp control circuit and a dimming control part control luminosity accurately and safely over a wide range.
