Filed: 1991-03-08
Abstract: PURPOSE: To attain highly precise black burst signal formation without complicating constitution by referring to one memory in which data such as a time interval, a side edge direction, a phase and a kind of a phenomenon are stored and a side edge formation data table. CONSTITUTION: An EPROM 2 which stores data such as a time interval, a side edge direction, a phase and a phenomenon being in progress of a PAL black burst signal, for example, the positive and negative side edges of a synchronizing pulse signal and the side edge of a color envelope or the like is referred by an address from a counter 1.

Abstract: PROBLEM TO BE SOLVED: To realize a high light receiving sensitivity even with a thin light absorption layer by a method wherein incident light is incident obliquely on a light incident edge and the incident light which is refracted by the light incident edge is passed obliquely to a layer thickness direction. SOLUTION: A flat-end fiber 18 is attached obliquely with reference to a package 19. Consequently, incident light is incident on a light incident edge 11 at an angle of incidence θ. Light which is refracted by the light incident edge 11 is incident at an angle of refraction ϕ with reference to a light absorption layer 13. For example, when light at a wavelength of 1.3 μm is incident, the refractive index of InP with reference to the incident is at 3.209, the angle of refraction ϕ is at 15.7 deg. when an angle of incidence θ is at 60 deg.. Refracted light passes through the light absorption layer 13 at an angle of 15.7 deg.. Even when the light absorption layer in a thickness of 0.5 μm is used, an effective absorption length is at 1.85 μm, and the large value of a light receiving sensitivity of 0.95 A/W or higher can be obtained. In addition, when the thickness of the light absorption layer is at 0.5 μm, the area of a light receiving layer can be reduced, and this semiconductor light receiving device can be operated at a high speed of 40 GHz or higher in a 3 dB band.

Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To transmit the entire rotating torque of a driving means in one directional rotation and limitedly transmit the rotating torque of the driving means in the other directional rotation by performing the transmission of the entire drive torque of the driving means by a cam clutch and the limited transmission of the rotating torque by a friction board. SOLUTION: Since a friction force as a cam 9 is fallen works when the minor diameter part 1a of a hub 1 rotates clockwise, a clearance is formed between the surface of the cam 9 and the inner surface of a sprocket 16, and the rotating torque of a geared motor 15 is not transmitted to the sprocket 16 through a cam clutch 8. Since a friction force as the cam 9 is raised works, conversely, when the minor diameter part 1a of the hub 1 rotates counterclockwise, all the cams 9 make contact with the inner surface of the sprocket 16 as they are pressed thereto, and the sprocket 16 is rotated integrally with the hub 1. Therefore, the rotating torque of the geared motor 15 is entirely transmitted to the sprocket 16 through the cam clutch 8.
