Title: Driving method for discharge display panel
Inventor: SEKI MASAHIKO
IPC: G09G3/294
Filed: 1989-06-22
Abstract: PURPOSE:To reduce ineffective electric power which does not contribute to discharging by setting the period of sustainment pulses longer than the period of access by write pulses independently of the access period. CONSTITUTION:The sustainment pulse period TSP is set to a specific multiple of the write access period TWP. Namely, write pulses and sustainment pulses are separated completely, only the sustainment pulses are made long in period, and the write pulses have the same waveform as usual. When the period of the sustainment pulses is set (k) times s long as the write access period, power loss Po based upon the capacity between electrodes is reduced to 1/K time as before. Thus, the period of the sustainment pulses is made long within a range wherein in discharging started with the write pulses can be maintained with the sustainment pulses, so the ineffective power loss due to the display anode-cathode capacity is reduced.

Abstract: PURPOSE:To easily perform assembly and to improve productivity by providing a first spring member to press an inner wheel in the axial direction of a fixed shaft, and a second spring member having an elastic modulus larger than that of the first spring member and to press an outer wheel in a direction opposite to the axial direction. CONSTITUTION:The outer wheel 15 is pressed downward with a wave washer 17 (second spring member) as a flat spring member to be interposed between a spring receiver 45 fixed at the upper end face part of a boss hole 41 with a tightening screw 43, and a pre-load is supplied to the wheel. Thereby, play in the axial direction can be prevented from occurring. Meanwhile, a compression coil spring (first spring member) 13 is interposed between the inner wheel 11 and a stopper part 37, and the inner wheel 11 is pressed upward in a direction opposite to the pressing direction of the washer 17. The elastic modulus of the spring 13 is set smaller than that of the washer 17. Since the elastic modulus of the washer 17 is set at a comparatively large value, it is easy to generate a large manufacturing error, but the manufacturing error can be absorbed by providing and deflecting the spring 13.

Abstract: PURPOSE:To reduce power consumption by forming a magnetic pole plate in a curved plate shape and then winding an excitation coil around a measurement pipe in an arc shape. CONSTITUTION:Magnetic pole plates 6, 6 are in curved plate shape corresponding to a cylindrical measurement pipe 1. At the same time, when an axis passing through a pair of magnetic poles (a), (a) is set to Y axis, the length in both directions of X and Z axes crossing it is formed to be smaller than an excitation coil 3 and the leakage of magnetic flux from the edge part of the magnetic pole plate 6 to a core 4 can be eliminated almost entirely by winding the coil 3 in an arc shape along the cylindrical measurement pipe 1, thus reducing power consumption without reducing the generated electromotive force of the title detector. Further, by forming the outer diameter of the coil 3 larger than the inner diameter of the measurement pipe 1, the leakage of magnetic flux from the edge part of the magnetic flux magnetic pole plate 6 to the core 4 can be further eliminated, thus further improving the excitation efficiency of excitation coil.

Abstract: PURPOSE:To enable alarm monitoring by branching the output signal of an optical amplifier by using an optical divider, and generating the alarm that the light output of the optical amplifier is broken, by using a part of the branched output signal. CONSTITUTION:The light output from a excitation laser diode 1 is inputted in an Er-doped fiber 3 via a polarization synthesis WDM coupler 2. On the other hand, a light input signal 8 is similarly inputted in the Er-doped fiber 3 via the coupler 2. The inputted light signal is amplified by the optical amplification action of the Er-doped fiber 3 and branched by a 10:1 divider 4. One light signal of 100/101 is outputted as the light output signal 9 of an equipment. The other light signal of 1/101 is sent, as the light signal for detection, to the input of a photodiode 5, and converted to a DC electric signal. Said signal is inputted in a comparator 6, and compared with a reference signal 7 as a reference value. When the output of the optical amplifier is decreased to lower than a specified level, the output of the comparator 6 changes and can be outputted as the alarm 10 that the light output is broken.

Title: Washstand bowl and method for cleaning it
Inventor: HAYAKAWA MAKOTO
IPC: B32B7/02
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To provide a bowl for a washstand wherein dregs of soap and stains of oil and fat can be easily washed off with running water. SOLUTION: A bowl 1 for a washstand has a bowl surface 5 covered with a surface layer contg. a photo-semiconductor. This bowl surface 5 is irradiated with UV rays from a UV lamp. and the bowl surface exhibits hydrophilic properties in accordance with photoexcitation of the photo-semiconductor. When the surface of the bowl is sufficiently hydrophilic, hydrophobic stains (such as oil and fat, carbon black and smoke) do not stick on the bowl surface in the presence of water. In addition, the stains sticked when there exists no water are washed off by making water run out. On the other hand, hydrophilic stains (mad stain, dust etc.) stick on the surface but the stains are washed off by making water run out.
