Abstract: PURPOSE:To form a uniform charge generating layer having high accuracy in thickness by dissolving a charge generating substance in an org. solvent to prepare a soln., dropping the soln. on an aqueous phase to form a thin film, applying pressure to the thin film by a proper means, and using the resulting Langmuir-Blodgett film. CONSTITUTION:A charge generating substance is dissolved in an org. solvent to prepare a soln., this soln. is dropped on an aqueous phase to form a thin film, and pressure is applied to the thin film. The resulting Langmuir-Blodgett film is transferred to an electrically conductive support to form a charge generating layer and a charge transferring layer is formed on the charge generating layer. It is necessary that the charge generating substance is dissolved in the org. solvent and can form a monomolecular film on the aqueous phase. A uniform charge generating layer having high accuracy in thickness can be formed by using the Langmuir-Blodgett film, so an electrophotographic sensitive body having high sensitivity and giving a uniform image can be produced.

Title: Pressure detector
Inventor: NISHIDA MINORU
IPC: G01L9/04
Filed: 1986-06-16
Abstract: PURPOSE:To accurately measure the pressure of compressive fluid by forming a sensing body in a flat plate shape and fixing it to the tip opening of a housing so that the opening is covered. CONSTITUTION:A detector has the cylinder housing 2, which is provided to the wall of a pressure chamber so that its tip faces the inside of the chamber. The housing 2 holds the metallic sensing body 1, part of it is made thin as a pressure receiving diaphragm 11, and a strain gauge 3 is joined with the opposite surface of the diagram 11 from its pressure receiving surface. The body 1 is formed in the flat plate shape and fixed covering the tip opening of the housing 2. Consequently, the pressure to be measured is applied directly to the diaphragm 11 of the body provided atop of the housing 2 and the diaphragm 11 deforms according to the applied pressure, so that an output signal corresponding to deformation strain is obtained from a strain gauge 3. Therefore, when the compressive fluid is measured, neither columnar vibrations nor a pressure drop is caused and a high-accuracy measurement is taken. Further, the body 1 is formed in the flat plate shape, so the manufacture is easy.

Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To simplify the structure by providing at least two beam deflectors for deflection scanning an incident beam, disposing a plurality of light sources between the beam reflectors and a photosensitive medium and converting and correcting the advancing path of a deflected beam. SOLUTION: The beam scanner 100 comprises four light sources 110 and a beam deflector 120, an advancing path converting means 130 for beam, and an incident beam correcting means 140 wherein a photosensitive medium 1 is scanned selectively with beam emitted from four light sources 110 provided in a frame 101 dependently on the hue thereof. A light emitted from the light source 110 enters a deflection disc 125 after being converted into a parallel light.

IPC: A61B5/05
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To find a medically appropriate intensity of the organism action current by a biomagnetism analysis apparatus. SOLUTION: A conversion factor group memory device 7 has previously obtained biomagnetism data properly combined with the intensity of the organism action current in a previously set power source position as the precursory knowledge, storing a group of conversion factors calculated with the precursory knowledge.

Title: Closed forging method of crankshaft
Inventor: BETSUSHIYO MICHIO
IPC: B21J5/02
Filed: 1978-11-13
Abstract: PURPOSE: To execute flash-free forging by letting the punches whose ends are of crankpin molding dies enter the material of the closed dies.  
     CONSTITUTION: The pre-formed material 1 is supplied between opened dies 3, 3', at which time punches 5', 5 are held vertically expanded. Next, when pressing is commanded to an outer press 9, the die 3' descends while holding the punch 3' and the dies 3 contact and stop with each other at the die parting face. At this time arrangement is so made that the material 1 accommodates in the die cavity and does not extrude to the die parting face. Then, when pressing is commanded to an inner press 10 and lower press 11, the punches 5', 5 advance while forcing aside the materiallc portion and are held in the dies at the punch ends. The remained material becomes crankpins 2c and the material having been forced aside fills the die cavity by making up the material insufficiency such of crankarm 2, crankshafts 2a, 2f, etc. This method eliminates the need for extraordinary screw-down force and improves yield as well.

Title: Parallel feedback type amplifier circuit
Inventor: INAGAKI YOSHIO
IPC: H03F1/30
Filed: 1985-06-28
Abstract: PURPOSE:To secure the stability of the band and noise characteristics against the variation of the power supply voltage and the temperature change, by reducing the change of the current flowing to an input element against said variations of the power supply voltage and temperature. CONSTITUTION:The junction potential is set at an approximately equal level VBE among diodes of a diode group 24 and between the bases and emitters of other transistors (TR). While the collector current IC of the 1st TR Q12 is set as IC=VBE/RC (RC: resistance of the 1st resistance element RC8). That is, the potential difference between both ends of the element RC8 is always kept at VBE with use of a bias circuit 20. This prevents the variation of the current IC due to the fluctuation of the power supply voltage or temperature and to attain the stable noise and band characteristics.

Title: Manufacture of semiconductor device
Inventor: OOSUGA NAOKI
IPC: H01L21/56
Filed: 1984-07-09
Abstract: PURPOSE:To obtain the titled device excellent in moisture resistance by strengthening the adhesion with the sealing resin by a method wherein a lead frame is treated with primer after satining by surface treatment with an etchant. CONSTITUTION:The etching treatment for the surface of lead frames is treatment with copper oxide by dipping in an alkaline solution in the case of copper of lead material, and coarsing treatment with a mixed solution of FeCl3+HCl in the case of 42 alloy. The resin comes to intrude into leads by forming many unevennesses in the lead surface, and sliding becomes difficult to occur. Besides, the resin becomes easier in intrusion because the surface formed by etching treatment is acicular, and the effect is much larger than the method of physical polishing. Further, the etching surface is treated with primer with a coupling agent or the like, thereby improving the adhesion of the lead frame with the resin.

Abstract: PROBLEM TO BE SOLVED: To prevent a transfer roller from being soiled by toner and to obtain an output image without soiling of the back surface by selecting the transfer roller in accordance with the size of transfer material and positioning it at a transfer position. SOLUTION: By using a control panel, an operator selects a transfer material of desired size so as to perform image forming. The transfer rollers 10a to 10c corresponding to the size of the transfer material selected based on this designation are positioned at the transfer position by the operation of a switching means 11. Next, the transfer material selected from plural paper supply cassettes loaded inside the device is carried to the transfer position of an image forming part. The transfer material is carried to the transfer position in specified timing with an image carrier carrying a toner image by a developing device, and controlled so that transfer bias voltage may be impressed on the transfer roller only when the transfer material passes through the transfer position.  The toner image formed on the image carrier is transferred on the transfer material and fixed by a fixing device, and the transfer material is ejected to the outside of the device.
