Title: Improvement of creep strength in weld zone
Inventor: OKITA SHIGERU
IPC: B23K9/00
Filed: 1989-11-09
Abstract: PURPOSE:To improve creep strength at a welded joint by welding a martensitic steel and a ferrite-martensite steel at specific bond line angle and specific softened region width and further carrying out heat treatment so that specific hardness is reached. CONSTITUTION:At the time of welding a martensitic stainless steel and a ferrite- martensite steel, the angle of bond line is limited so that bond lines between a base metal and a weld metal in respective layers form angles of 70-90 deg. with respect to the surface of a steel plate. Further, a weld zone in which the width of a region more softened than the base metal due to welding and postheat treatment is regulated so that it is smaller than the plate thickness in the weld zone is formed. Moreover, heat treatment is carried out so that Vickers hardness in the softened region and Vickers hardness in the weld metal satisfy an inequality WMHv>=HAZHv+20 (where WMHv and HAZHv represent Vickers hardness in the weld metal and Vickers hardness in the softened region, respectively). By this method, creep strength in the weld zone can be improved, and a welded joint usable at high temp. for a long time can be obtained.

Title: Manufacture of optical fiber coupler
Inventor: MIYAMOTO SUEHIRO
IPC: G02B6/28
Filed: 1988-11-18
Abstract: PURPOSE:To easily manufacture an optical fiber coupler and, at the same time, to improve the reproducibility of the coupler by using a fiber preform (multicore type fiber preform) equipped with >=2 cores, and heating part of the fiber obtained from the preform from the outside. CONSTITUTION:A multicore type fiber preform (base material) equipped with multiple cores, for example, two cores 17 is produced and the preform is drawn to a prescribed outside diameter while the preform is heated. The fiber F drawn from the preform is put in a heating furnace 11 and part of the fiber F is heated from the outside after the fiber F is cut to an appropriate length. The heating is performed with laser light by controlling the temperature so that the fiber F itself does not deform by monitoring the temperature with a radiation thermometer 16 for monitoring temperature. When the fiber F is heated, the cores 17 of the fiber F are coupled with each other, since thermal diffusion takes place at the parts 17a of the cores 17 irradiated with the laser light and the refractive index distributions of the cores 17 are deformed. Thus a optical fiber coupler which can be manufactured easily and is excellent in reproducibility can be obtained.

Title: Triangle wave generating circuit
Inventor: SUEMATSU MUTSUMI
IPC: H02P7/29
Filed: 1985-12-26
Abstract: PURPOSE:To attain accurate pulse width modulation by inserting or combining a capacitor circuit in an output circuit of a triangle wave signal and using the capacitor circuit so as to eliminate the drift component of the offset included in the triangle wave signal. CONSTITUTION:A capacitor 63 is inserted in the output circuit of an integration device 61. The capacitor 63 has a capacitance decided in response to the frequency of the triangle wave signal to block the passing of a DC component in the triangle wave signal outputted from the integration device 61 and the AC component is transmitted as it is. Since the drift component of the offset is substantially a DC, it is eliminated when it passes through the capacitor 63, resulting that the triangle wave signal whose drift component is reduced is outputted. Thus, the accurate pulse width modulation is applied at all times.

Filed: 1988-11-21
Abstract: PURPOSE:To attain clear image pickup even if an object with high and low brightness exists within the same picture angle by generating a new luminance signal extended nonlinarly from the luminance signal and a new color difference signal amplified at a proper amplification factor. CONSTITUTION:Color signals R, G, B subjected to color separation are converted into color difference signals R-Y and B-Y and a luminance signal Y by a matrix circuit 9, and the result is supplied to color difference correction circuits 11, 12 and a brightness correction circuit 10 respectively. As shown in figure, a new luminance signal Y' is outputted with the same linear amplification factor with respect to the luminance signal input of brightness YO, YM within a range of preset minimum brightness YO and maximum brightness YM and a new signal Y' with a nonlinear amplification factor to the signal Y between the brightness sets. The amplification factor in this case is set to a higher value than the amplification factor at the sets of the brightness YO, YM to expand the intermediate luminance signal. Thus, the brightness of an object with a low brightness is emphasized and the picture at the darkest and brightest state is left as it is. Moreover, the correction to expand the color difference signal is processed altogether to suppress the event of whity hue.

Title: Suction port body of vacuum cleaner
Inventor: TAKEMOTO RITSUO
IPC: A47L9/02
Filed: 1993-11-22
Abstract: PURPOSE:To provide a suction port body of a vacuum cleaner which achieves higher cleaning workability by improving running performance with the pushing of the suction port body. CONSTITUTION:In a cleaning by pushing a hand operating section of a hose, a pressing force F having a vertical component force Fb pressing a suction port body 11 onto a floor surface F1 works on the rotating shaft 33 of a communication pipe 31. In the case where the floor surface F1 is a carpet, a running wheel 36 supported on the rotating shaft 33 sinks down into the carpet F1. The carpet F1 pushes up the undersurface of a case body 15 to move the case body 15 upward relative to the rotating shaft 33 supported vertically in a slender engaging slot 27 so that the undersurface of the case body 15 does not press the carpet F1 resulting in a drop in friction resistance achieving cleaning workability with higher running performance. As a communication pipe 31 turns upward. a moment Em of a reaction Ea of an energizing force E is generated with a plate spring 42 to turn the communication pipe 31 downward. Thus, the case body 15 is pressed properly onto the floor surface F1 relative to the communication pipe 31 to allow the maintaining of the airtightness on the undersurface of the suction port body 11, thereby achieving a higher suction efficiency.

Abstract: PURPOSE:To use waste water to efficiently remove moisture contained in hot air for drying clothing by introducing the hot air for drying the clothing through a drainage to a dehumidifying part, dehumidifying the hot air by a water cooling, and arbitrarily supplying cooling water when the temperature of the waste water rises when the clothing is to be dried. CONSTITUTION:When the clothing is to be dried, a drain control valve 12 is opened. Further, the waste water at rinse-washing time or dewatering time is stored in a cylindrical body 15 of a dehumidifying part 14. When a rotating drum 4 is rotated, a heater 9a of a drying means 9 is energized, and a blowing fan 9b is operated, the hot water evaporates the moisture from the clothing in the rotating drum 4, passes from a drain hole 10 through a drain pipe 13 as exhaust air containing the moisture, and reaches the inside of the cylindrical body 15 of the dehumidifying part 14. The exhaust air having a high temperature and much moisture is cooled in the cylindrical body 15, and the moisture is made into dew and removed. The exhaust air is returned through a return pipe 17 to the drying means 9. Further, the rising of the temperature of the water in the cylindrical body 15 can be suppressed, and more efficient dehumidification can be maintained by arbitrarily supplying the cooling water from the second water feeding hose 8.
