Title: Driving shaft excellent in fatigue characteristic
Inventor: YAMANAKA JUNJI
IPC: F16F15/34
Filed: 1996-05-02
Abstract: PROBLEM TO BE SOLVED: To avoid any fatigue strength drop in a mounting part by setting up a weight in a part of plural layers of annular heat shrinkable resin, and installing a balance weight whose Young's modulus is the specified value after the shrinkage of an inner layer contacting with a driving shaft. SOLUTION: This balance weight consists of an annular heat shrinkable resin part 8 locking this balance weight by its own shrinkage and a weight part 7 to adjust any rotational drag with the mass. This resin part 8 is a multilayer structure, using such one as having elasticity of less than 3000N/mm<2> in Young's modulus after being shrinked to an inner layer 9 contacting with a driving shaft. Attachment to the driving shaft is as follows that the balance weight is inserted into an external part of the driving shaft, then the weight part 7 is set up in an objective position. The initial outer diameter of the resin part 8 is made large than that of the driving shaft, and after being inserted thereinto, this resin part 8 is contracted by heating and thereby the weight part 7 is locked tight.  Welding is not used for the installation, but elastic resin is used for the inner layer, and since any strain being transmitted to the balance weight from the driving shaft is interrupted, any possible fatigue is thus avoidable.

Filed: 1989-05-26
Abstract: PURPOSE:To enhance operation sensing performance by providing a pressure sensing piece for sensing operation of a normal/reverse switch layer adapted to press an operation pin under pressure of a return spring in a space between the return spring for pressing and projecting a linear slider before a switch case and the operation pin. CONSTITUTION:A pressure sensing piece F for sensing the operation of a normal/ reverse switch lever 51 adapted to press an operation pin 37 under pressure of a return spring 32 is provided in a space between the return spring 32 for pressing and projecting a linear slider 28 before a switch case and the operation pin 37. Accordingly, upon switching operation of the normal/reverse switch lever 51, the operation pin 37 is temporarily associated with the pressure sensing piece F during the switching operation, to be laterally advanced against the pressure of the pressure sensing piece F. At this moment, an abrupt fluctuation of the pressure is generated to cause a change in resistance to a lever 13, thus transmitting an apparent operation sensing force to the lever 13. Therefore, the switch can efficiently be provided with an operation sensing function.

Title: Optical fiber connector
Inventor: SUZUKI NOBUO
IPC: G02B6/38
Filed: 1982-08-02
Abstract: PURPOSE:To average the interference of multiple reflected light and to enable the prevention of reflection without spoiling a connection characteristic, by inclining the spacing between the end faces of optical fibers with respect to the optical axes, and forming the same into a wedge shape. CONSTITUTION:The forward end 6 of a ferrule 2 is finished by polishing together with a fiber 3 to the slope of an angle theta to the face 7 at right angles to the optical axis of the fiber. A positioning key 5 is provided on the central axis 8 of the polished surface. A member 9 for arraying the ferrule 2 is formed in the position apart further by alpha deg. from the position where the positioning grooves 11 and 12 deviate from each other by 180 deg.. If such members are assembled, a relative deviation in the central axes 8 of the slopes is produced and the spacing has the wedge shape of the angle DELTAtheta. Therefore, the reflected light B for return is escaped to the outside of the fiber and since the multiple reflected light C in the advancing direction of the light is averaged in the interference of light, the width in the fluctuation of the loss is decreased. The reflection is thus prevented without spoiling the connection characteristic.

Filed: 1990-05-28
Abstract: PURPOSE:To form potential barrier between pixels, prevent running of carrier between pixels and prevent leak of light into the lower circuit by providing light shielding Schottky electrode between pixel electrodes. CONSTITUTION:The incident light through the ITO film 10 generates carrier within the photoconductive film 8, hole is extracted from the ITO film 10 through the p<+> type hydrogentated amorphous silicon film 9 and electrons reach the pixel electrode 7 running through the photoconductive film 8. The accumulated charges are transferred to CCD 11 through the gate 12 when a pulse voltage is applied to the CCD electrode 3 and are then transferred sequentially to an external circuit by the CCD. In this timing, the light shielding Schottky electrode 15 is set to almost the same potential as the p<+> type layer and a potential barrier which prevent running of electrons is formed between adjacent pixels. As a result, the carrier generated in the pixel B never flow into the pixel A and flow of carrier to the pixel electrode 7' from the pixel electrode 7 can also be prevented. Moreover, generation of leak current within the lower circuit can also be prevented.
