Title: Surface roughening method for organic electrophotographic sensitive body
Inventor: SAKAI KIYOSHI
IPC: G03G5/00
Filed: 1989-12-19
Abstract: PURPOSE:To prevent the cleaning defect by the inversion of a cleaning blade and the chipping of an edge part, etc., and the flaw patterns on images by allowing the swarf of the photosensitive body generated by the roughening of the surface thereof to remain on the surface of the photosensitive body. CONSTITUTION:The swarf of the photosensitive body 2 generated by the roughening of the surface thereof is made to remain on the surface of the photosensitive body 2. Namely, the photosensitive body 2 is polished by a film-like photosensitive material of 6.0 mum film grain size in the environment of 23 deg.C, 50% relative humidity and 50 lux light quantity on the surface of the photosensitive body 2. The average surface roughness of this time is 0.8 mum, the min. surface roughness 0.5 mum and the max. surface roughness 1.4 mum. The photosensitive body which holds the swarf generated in this polishing process is incorporated into the electrophotographic device having the functions for electrostatic charging, image exposing, developing, transferring and cleaning by using a polyurethane rubber blade, by which the repetitive image forming is executed. The cleaning defect by the inversion of the cleaning blade, etc., and the flaw patterns on the image are prevented in this way.

Title: Controller for pure water flow rate
Inventor: OSUGI SHIGERU
IPC: F16K31/06
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To maintain pure water flow rate at a constant value with high precision even if the pressure drop across an on/off valve varies owing to variation in the temperature of pure water. SOLUTION: This controller 1 for the pure water flow rate is equipped with a pilot regulator(PR) 2 which adjusts the pure water flow rate through the operation of working pressure Pa, an electronic regulator (EV) 3 which adjusts the working pressure Pa applied to the PR 2, a Karman flow rate sensor 4 which measures the pure water flow rate outputted from the PR 2, and the on/off valve 5 which allows the pure water passed through the flow rate sensor 4 to flow or cuts it off. The controller 1 balances the working pressure Pa adjusted by the EV 3 to the secondary pressure P2 of the PR 2 to control the flow rate of the pure water outputted from the PR 2 to a constant value. The flow rate sensor 4 outputs its measured value electrically. The EV 3 is equipped with a couple of proportional valves which adjust the working pressure Pa and a PID circuit.  The PID circuit performs feedback control over the working pressure Pa applied from the proportional valves to the PR 2 according to the measured value so that the measured value of the flow rate sensor 4 becomes constant.

Title: Refrigerator provided with drying function
Inventor: HONGO HIROKO
IPC: F25D11/00
Filed: 1993-12-24
Abstract: PURPOSE:To prevent the generation of condensate on a dried food taken out of a refrigerator when dried material, such as the dried foods and the like, is stored in a refrigerator by a method wherein a heat dissipating pipe is arranged in the drying chamber in the refrigerator to conduct heated refrigerant for a refrigerating cycle while the flow rate of the refrigerant is controlled. CONSTITUTION:A refrigerating chamber 3, a freezing chamber 5 and a vegetable chamber 7 in a refrigerator 1 are cooled by sending cold air through a fan 37 respectively. On the other hand, cold air is introduced into a drying chamber 9 through a cold air inflow port 57 having a damper 55. Thereafter, the cold air is introduced into an evaporator 35 from a cold air outflow port 59 through a cold air discharging passage 61. A drying chamber heating pipe 25, equipped with a changeover valve, and a heater 41 are arranged around the drying chamber 9. In this case, the changeover valve and the heater 41 are controlled by a control unit based on a difference between detecting temperatures of a drying chamber inside temperature detecting sensor 47 and a refrigerator outside temperature detecting sensor 51 so that the difference is brought into a given temperature range. According to this method, the generation of condensate on a dried food can be prevented when the food is taken out of the refrigerator 1.

Title: Short-circuit detector for low-voltage side driving load
Inventor: ROBAATO TEII AANTSU
IPC: H02H1/00
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To control a low-voltage-side driver with only a single conductor and to receive a feedback failure signal by feeding a control signal from a control means to the remote drier of a load via a local driver and comparing a grounded signal with a reference voltage in a remote comparator. SOLUTION: When there is a request for driving a load 20 for a microprocessor 10 during a normal operation, the microprocessor 10 transmits a high-level control signal to a local driver circuit 12, lowers a signal level on a single conductor 16, and maintains a remote drive circuit 32 in an 'OP' state. When the load 20 is short-circuited, a transistor 34 cannot set a signal on a conductor 35 to a ground level and a flip-flop 30 cannot be reset as a result of a comparison by a comparator 36, so that a transistor 44 is raised to a high level by a signal on the single conductor 16. A high-level signal on the single conductor 16 indicates that the remote load 20 is short-circuited for the microprocessor 20.

Abstract: PROBLEM TO BE SOLVED: To provide an analysis method for every form of element wherein emission of a suspension is caused in a plasma flame to simultaneously measure the spectral intensity of a measuring component element by a time division method and a fractional determination is performed from the level of the spectral intensity and the frequency of the occurrence. SOLUTION: A suspension 1 is atomized by a nebulizer 3 and introduced into a plasma torch 2 via a spray chamber 4 to generate an excitation spectrum of mist components by a plasma flame 6. The spectrum is selected to a specified wavelength by a spectroscope 7 to be converted to an electric signal by a photomultiplier 11. An integrator 12 integrates a spectral intensity signal of the photomultiplier 11. A plasma intensity data converted into a digital signal by an A/D converter 13 is stored into a memory 14 in a time series. A microcomputer 15 performs a numerical processing of the plasma intensity data in terms of the spectral intensity. Thus, the contents of the dissolved and non-dissolved portions of measuring component elements can be simultaneously measured once from the spectral intensity and the frequency of occurrence.  The sampled calibration data undergoes a calibrating operation at a calibration computing section.
