Patent JP-S5981618-A (JP)
Title: Optical coupler
Inventor: MATSUI TERUHITO
IPC: G02B27/28
Filed: 1982-11-01
Abstract: PURPOSE:To obtain an effective isolation function for reflected light from not only the incidence end of an optical fiber but the other end by such simple constitution that a polarization plane conservative optical fiber is connected to the tip part of an optical fiber for transmission. CONSTITUTION:The polarization plane conservative optical fiber 7 with length nL/2 is connected to the light source side of an optical fiber 5. Light from a semiconductor laser 1 is coupled with an end surface of the polarization plane conservative optical fiber 7, but reflected light from the other end surface 7b, i.e. incidence surface 5a of the optical fiber 5 is still polarized circularly when returning to the incidence surface 7a; and it is converted into linear polarized light by a quarter-wavelength plate 4 and a polarizing prism 3 to become perpendicular to the polarization direction of the semiconductor laser 1, and led out to the other side by the polarizing prism 3 without being coupled with the semiconductor laser 1 again. Further, the majority of light returned by being reflected by the projection end 5b of the optical fiber 5 is not coupled with a polarization plane conservative optical fiber 7 at the connection surfaces 5a and 7b and the isolation function is held.

Title: Coil for transformer
Inventor: SHIODA HIROSHI
IPC: H01F27/28
Filed: 1985-09-02
Abstract: PURPOSE:To reduce the external thrust in an electromagnetic axis direction at the time of an arm short-circuit and to contrive miniaturizing and making light weight of a transformer and improving reliability by making a half of even number parallel conductors constituting each unit twin coil of double star transformer winding for the first secondary winding and the other half for the second secondary winding. CONSTITUTION:A unit twin coil 5 is constituted with 2n parallel conductors and of these, (n) conductors are used for u-o1 secondary winding 3 and the other (n) conductors for o2-x secondary winding 4. Four outlet marks, u, o1, o2, x are given to one unit twin coil 5. The lead wire of each unit coil 5 is connected to an outlet conductor 6 in accordance with each outlet mark and many parallel circuits are constructed. As a result, two secondary windings geometrically occupy the same space and even in the case of the arm short- circuit of any winding, the ampere-turn distribution in the direction of the coil heights of the secondary winding and the primary winding can completely be made coincident. Since the external thrust in the direction of axis is removed by the generation mechanism, the reinforcement of a coil support material is not required.

Abstract: PURPOSE:To realize copying work high efficiency and excellent image quality by a compact copying machine by switching the linear velocity of a photosensitive body and variably controlling process conditions so that the required image quality is maintained at the same time. CONSTITUTION:An operation unit 41 is provided with a copying speed set means which sets the multistage copying speed modes of H (high speed). M (medium speed) and S (lowest speed) so that they can be switched by the operation input of copying speed switching keys 53H, 53M and 53S. In such a case, a copying speed means the number of copied sheets produced per unit time by the copying machine 1. Then, the copying speed is varied by converting the linear velocity of the photosensitive body 31 and the processing speed (the actual image producing time)of a processing means. Since such a processing condition that the prescribed image quality of the copying machine is maintained is variably controlled to be the optimum condition in accordance with the switching of the linear velocity of the photosensitive body in such a way, the copying work with the excellent image quality and the high efficiency is realized by the compact copying machine.

Title: Rotor of rotary apparatus
Inventor: IMAMURA ISAO
IPC: B01D59/20
Filed: 1984-09-17
Abstract: PURPOSE:To simply prevent the adverse effect of the dust, which is generated at the time of the destruction of a rotor, exerted on the rotary capacity of the rotor of other rotary apparatus, by forming the rotor by bonding carbon and aramid fiber layers by plastic. CONSTITUTION:The rotor 10 of a rotary apparatus is formed of three fiber layers 10A, 10B, 10C each comprising reinforcing fibers consisting of carbon fibers CF and aramid fibers AF and formed, for example, by winding carbon fibers and aramid fibers. As a result, carbon fibers are cut when the rotor 10 is destructed and apt to generate dust but, because aramid fibers generate no dust from the aspect of the properties thereof when cut along with said carbon fibers and are apt to become fluffy to be entangled to each other, the dust of the carbon fibers is confined in the fluffy aramid fibers and the aramid fibers have action reducing the generation of dust from the rotor 10 as a whole.

IPC: G01R19/00
Filed: 1994-08-16
Abstract: PURPOSE:To provide an optical fiber-type current sensor which is resistant to a vibration and whose S/N ratio is high. CONSTITUTION:Electric-to-optical transducer part 16 is installed on the input side of light at a sensor part 1 around which an SMF (a single-mode fiber) has been wound in a coil shape, and an analyzer 9 is installed on the output side of light. An optical-to-electric transducer part 17 is connected to the electric-to-optical transducer part 16. The SMF for the sensor part 1 is fixed by a fixation means 4. Optical waveguides 13, 14, 15 for an MMF (a multimode fiber) are coupled to the input/output side of the sensor part 1. Light from a light-emitting element 8 is incident on the sensor part 1, with good efficiency, from the electric-to-optical transducer part 16, and the S/N ratio of a sensor is enhanced. Light passing through the sensor part 1 is modulated by a magnetic field, and its degree of modulation is detected by photodetectors 10, 11. Since the optical waveguides 13, 14, 15 are formed out of the MMF, it is possible to prevent a noise caused by a modulation from being generated due to vibration.

IPC: H03K19/017
Filed: 1993-08-03
Abstract: PURPOSE:To ensure the satisfactory noise reduction effect by sending the voltage of an intermediate level to an output terminal in an output preparing period. CONSTITUTION:In an output control circuit 6, the MOS transistors Q3 and Q4 are turned on and the NMOS TR Q9 and Q10 are turned off respectively when the output of an output preparing period detecting circuit 7 is kept at an L level. Then a buffer circuit 4 transmits a data signal. When the output of the circuit 7 is set at an H level, the TR Q3 and Q4 are turned off and the TR Q9 and Q10 are turned on respectively. Then an intermediate level of the voltage (1/2) VCC (power supply voltage) generated by an intermediate level generating circuit 8 is supplied to the circuit 4 as a power supply. Therefore the circuit 4 gives the intermediate level of the voltage (1/2) VCC to an output terminal 5 regardless of the output logical level of a latch circuit 3.
