IPC: H03M13/00
Filed: 1987-10-14
Abstract: PURPOSE:To execute error correction with comparatively small computing quantity by having an operating means to execute addition, multiplication and division on a finite field, obtaining the degree of a polynomial, judging the relation of sizes with a constant determined in advance and executing the repeating operation of Euclidean algorithm to obtain a greatest common divisor. CONSTITUTION:In an error correcting circuit using a remainder polynomial code based on reminder theorem by a Chinese mathematician, an operating means 1 is obtained to execute the addition, multiplication and division on a finite field GF(2<m>) [(m) is a >=1 integer]. When a code V' is received, a decoding device obtains an expression F'(x) and a degree deg[F'(x)] by the operating means 1. This obtained deg[F'(x)] is compared with a number kd, which is determined in advance by a comparing means 2. As the result of the comparison, when the deg[F'(x)] is smaller than kd, it is judged to be 'there is no error' and F'(x) is adopted as expression F(x) as it is. As the result of the comparison, when the deg[F'(x)] is larger than kd, it is judged as 'there is an error' and the output of an error correcting means 3 receiving F'(x) is adopted as the expression for F(x). Thus, with the comparatively small operating quantity, the error can be corrected.

Title: Lens shutter driving mechanism used also as lens driving mechanism
Inventor: KOBAYASHI KOICHI
IPC: G03B9/24
Filed: 1991-09-11
Abstract: PURPOSE:To improve a mechanism for driving a lens and a shutter blade where a step motor is used as a driving source. CONSTITUTION:When a main driving member 4 connected to the motor 1 is rotated counterclockwise, a lens driving member 5 connected to the lens is rotated counterclockwise in a state where its step part 5d is engaged with a pin 4a. At such a time, a recessed cam 4g passes a cam follower 7b, and the clockwise rotation of the cam follower 7b is regulated by the cam edge 5f of the member 5, and the clockwise rotation thereof is regulated by the cam edge 4f after the member 5 is rotated counterclockwise. When the member 4 is rotated clockwise by engaging with a ratchet 5a at a focusing position, the cam follower 7b is released from the cm edge 5f at such a time, so that the cam follower 7b falls in the recessed cam 4g from a cam edge 4f, and an opening and closing member 7 is rotated clockwise. Therefore, the opening and closing lever 7 is actuated only in the case of the initial restoration of a main driving member even when a one-way clutch is not provided.

Title: Torque fluctuation preventing structure in oscillating swash plate type compressor
Inventor: OTA MASAKI
IPC: F04B27/08
Filed: 1988-10-14
Abstract: PURPOSE:To prevent the generation of torque fluctuation by disposing the coupling positions of piston rods against an oscillating swash plate unequally such as to be shifted from the positions of equal spacing toward specific zones which are the troughs of torque fluctuation. CONSTITUTION:The coupling positions of remaining piston rods 12b-12e excluding a piston rod 12a against an oscillating swash plate 9 are shifted from the positions of equal spacing, and this shifting direction directs an angle position thetax from the coupling position to the rotating position of the rod 12a. Due to this shifting from the position of equal spacing, the top dead center time of pistons in cylinder bores 1b-1e is shifted toward the turning angle position thetax, and the local peaks of torque fluctuation corresponding to the respective cylinder bores 1b-1e are shifted toward the turning angle position thetax. The big troughs of the torque fluctuation in one cycle are prevented from generating owing to the averaged torque fluctuation, which results in preventing noise, vibration and rattling as well as the fatigue failure of an axis of rotation 4.
