Title: Method of work surface inspection
Inventor: KATO KENJI
IPC: G01B11/30
Filed: 1993-11-22
Abstract: PURPOSE:To inspect the existence of an uneven part on a work surface with good accuracy by using an optical inspection apparatus which is provided with a light-projecting means which radiates inspection light toward the work surface and with an imaging means which receives reflected light from the work surface. CONSTITUTION:A focal plane 22 for an imaging. means 2 is situated on the side in front of a work surface A with reference to the whole region of an effective inspection range on the work surface A which can receive reflected light by means of the imaging means 2. Even when an uneven part B on the work surface A is small and reflected light R from the part is received by the imaging means 2, a part (b') on the focal plane 22 on which the reflected light R is not incident becomes a part (b) corresponding to the uneven part B on an image face 20 for the imaging means 2. As a result, the part (b) becomes a dark part because the reflected light R does not form an image, and the existence of the uneven part can be inspected with good accuracy.

Title: Electrophotographic printer
Inventor: YAJIMA HIROYUKI
IPC: G03G15/20
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of wrinkles of a printing medium and further, the occurrence of a jam, and to enhance the quality of an image. SOLUTION: This electrophotographic printer is provided with first and second rollers for carrying the printing medium, a photoreceptor drum 13 disposed on the downstream side from the first/second rollers, a transfer roller 14 and third and fourth rollers which are arranged on the downstream side from the drum 13 and the transfer roller 14 and rotated to carry the printing medium.

Title: Pressure vessel for water supply
Inventor: NIBU HITOSHI
IPC: F15B1/08
Filed: 1988-11-21
Abstract: PURPOSE:To eliminate deterioration of city water and generation of odor, both of which are caused by the bleaching powder (ClO) added to the city water, by forming a partition wall of the captioned vessel by means of either a polyolefine-system, thermoplastic elastomer or a thermoplasetic elastomer as a copolymer of polyurethane and chloroethylene. CONSTITUTION:A buggy bladder 2, which is made of soft, elastic body and which can freely change its shape, is hung in a vessel main body 1. Water can freely flow into or out of the bladder 2, thereby forming a water chamber 8. On the other hand, the vessel main body 1 is filled to gastight with gas like air like air or nitrogen (N2) through a gas filling port 9 until the pressure suitable for use-conditions as a pressure vessel for water supply is obtained, thereby forming a gas chamber 10. The material of the bladder 2 of this vessel for water supply should be either polyolefine-system, thermoplastic elastomer or a thermoplastic elastomer as a copolymer of polyurethane and chloroethylene. Owing to high chlorine-resistance of this material, deterioration of and generation of odor from city water, both of which are caused by bleaching power (ClO) added to the city water, can be prevented.

Title: Resin-sandwiched laminated metallic belt coil
Inventor: OMURA YASUHIRO
IPC: B32B15/08
Filed: 1988-11-21
Abstract: PURPOSE:To prevent the present belt coil from deformation at the time of temporary storing, and to securely commercialize as a cut sheet by arranging the holding member between resin layers in the resin layer. CONSTITUTION:In the manufacture of a metallic coil, when, for instance, one surface of a metallic belt is coated with resin, and another metallic belt is arranged and pressure-bonded onto said resin surface, the holding members 5 between the resin layers are inserted at the time of pressure bonding. For instance, the nonferrous metals such as copper and aluminum, etc., and nylon or polypropylene, etc., are formed into the wire having the diameter almost corresponding to the thickness of the resin layer, and this wire is used as the holding member. This holding members 5 are arranged like a stripe in the resin layer 4 in the longitudinal direction of the resin-sandwiched laminated metallic belt 1. Thus, since each resin layer in the laminated metallic belt coil is not crushed by arranging the holding members between resin layers in the layer of viscoelastic resin, the true circular coil in the state of the coil being wound up without deformation may be kept (temporarily stored), whereby the shearing operation in next process is achieved smoothly.

A primary side is constituted so that the rectifying smoothing voltage at a level corresponding to an AC input voltage level can be inputted, by a normal full-wave rectification circuit instead of a double-voltage rectifying circuit.

Title: Overheat detector for power device
Inventor: NISHIURA SHINJI
IPC: H01L27/088
Filed: 1991-11-08
Abstract: PURPOSE:To form a temperature detector in a simple structure by connecting a diode in series with a MOSFET, applying a reverse bias to the diode, and connecting the other end of the diode to the GND. CONSTITUTION:A diode 1 and a depression type MOSFET(MOSFET) 2 having a source, a drain and a gate 22 are connected in series. The diode 1 is connected to a buffer 5 in which an FET is used at a midpoint of the MOSFET 2. The buffer 5 has a predetermined threshold voltage. The reverse leakage current of the diode 1 is varied depending upon the square root of temperature, and increased as the temperature rises. When an intermediate voltage Vc of the MOSFET 2 exceeds the threshold value of the buffer 5, it is set to output a signal. Thus, the detection signal of an abnormal temperature can be output, and damage of a power IC can be prevented by controlling it by using the detection signal.
