Filed: 1990-10-26
Abstract: PURPOSE:To provide excellent positive hole transporting ability and high- sensitive low and stable residual potential characteristics by containing polysilane in a charge transport layer and forming an intermediate layer, containing a charge transport material, between a charge generating layer and the charge transport layer. CONSTITUTION:A sensitive layer 5A is formed on a conductive support 1, and the sensitized layer 5A is formed by laminating together a charge generating layer 2, an intermediate layer 3, and a charge transport layer 4. Polysilane is contained in the transport layer 4 and the intermediate layer 3 containing a charge transport material is formed between the generating layer 2 and the transport layer 4. By containing the charge transport material in the intermediate layer 3, a role to transport a positive hole where light is generated in the generating layer 2 is performed to improve sensitivity. By reducing a difference in a ionized potential between polysilane used for the transport layer 4 and the charge transport material added in the intermediate layer 3, sensitivity is improved. This constitution provides a sensitized band which is excellent in positive hole transporting ability and has high-sensitive low and stable residual potential characteristics.

Title: Device and method for damping bobbin thread bobbin of sewing machine
Inventor: HARA KAZUMASA
IPC: D05B57/26
Filed: 1991-10-09
Abstract: PURPOSE:To obstruct idle running of a bobbin thread bobbin, and to prevent generation of the idle running by providing a damping member in a specific range part in the radial direction moving control direction of the bobbin thread bobbin of a bobbin supporting part. CONSTITUTION:In a state that a bobbin thread T is drawn out normally by a bobbin thread bobbin 4, the bobbin thread bobbin 4 is drawn closer to the drawing-out direction C of a thread, therefore, on the anti-drawing-out side of the bobbin thread bobbin 4, a cavity part is generated against an inside wall 6 of a bobbin thread containing recessed part 2. Also, a contact of the outside peripheral, part 5 of the bobbin thread bobbin 4 and the inside wall 6 moves within a prescribed range, therefore, a cavity part of the opposite side of drawing out a thread also moves. When the bobbin thread bobbin moves in a normal state, the minimum cavity part is generated. To the inside wall which faces the cavity part in this normal state, a thin tape-like clamping member 16 whose friction coefficient is large such as a urethane rubber material is stuck, or provided integrally by two-color molding. That is, the clamping member 16 does not work on the bobbin thread bobbin 4 in a normal state of the bobbin thread bobbin, works only at the time when it becomes a floating state and returns it quickly to a normal state.

Title: Focusing position detecting device
Inventor: TAKAHAMA YASUTERU
IPC: G03B13/36
Filed: 1990-10-30
Abstract: PURPOSE:To perform high-precise detection of a focusing position without being influenced by the change of magnification of an observation optical system by changing the projection magnification of an image-reforming optical system according to the change of observation magnification of an observation optical system. CONSTITUTION:Photo flux diameter changing lens groups 8-1 - 8-n changed into photo flux diameters different from each other are insertably located to an image-reforming optical system R. When an NA value of injection of an objective lens having intermediate magnification capable of detecting an excellent focusing position is A1, a photo flux diameter change lens having a photo flux diameter enlargement factor of approximate A1/A2 is selected from an objective lens so that an NA value of injection is A2, and inserted in an optical path. Thus, NA of light entering two CCD arrays 11 and 13 can be always kept approximately at a constant value in a state that the CCD arrays 11 and 13 are fixed to various object lenses in a range of low magnification to high magnification. This constitution performs high-precise detection of a focusing position without being influence by magnification of the object lens.

Abstract: PURPOSE: To eliminate the relative rotation between a sealing ring and a stressing ring by making an outer surface of the sealing ring into a conical surface with the cone angle within a predetermined range, increasing an outer diameter of the sealing ring from the low pressure side to the high pressure side. CONSTITUTION: An outer surface of a sealing ring 5 is a conical surface with a cone angle β of 30-60 degrees. The diameter of the conical surface is continuously increased from the low pressure end to the high pressure end of the sealing ring 5. An outer diameter of a groove 4 arranged in a housing 2 is larger than a stressing ring 6, and the width of the groove 4 is slightly larger than the axial length of the sealing ring 5. The stressing ring 6 sealingly abuts one of the side surfaces of the groove 4. The axial pressure of the stressing ring 6 on the other side surface of the groove 4 is born by the sealing ring 5. A pressure relief groove 58 is arranged on the end surface at the high pressure side.  Consequently, the stressing ring 6 is wedged in the gap between the side surface at the low pressure side of the groove 4 and the conical outer surface of the sealing ring 5, and pressed to the side surface at the high pressure side of the groove 4.

IPC: H05B6/68
Filed: 1987-11-18
Abstract: PURPOSE:To prevent cooking completion time from being varied owing to temperature properties of a piezo-electric element sensor even when heating is repeated by cooling the piezo-electric element sensor by a cooling fan for ratio frequency radiation sections for the period of a specified time after cooking has been completed. CONSTITUTION:A piezo-electric element sensor 1 is incorporated in place of a conventional temperature sensor. The supply voltage of a radio frequency radiation section 7 is built up by signals from a controller 4, upon completion of cooking, the cooling fan 8 is kept rotating for the constant period of time thereafter so as to let the piezo-electric element sensor 1 be cooled by way of route indicated by solid arrow lines 23 for letting an increase in temperature be restrained. By this constitution, even if the piezo-electric element sensor 1 has its own temperature properties, cooking completion time will never be extended as temperature is increased.
