Title: Method for controlling rear wheel steering device
Inventor: TAKAHASHI AKIRA
IPC: B62D111/00
Filed: 1993-06-21
Abstract: PURPOSE:To reduce the load of an actuator so as to effect downsizing by making a correct judgement of the load condition of the actuator for steering the rear wheels in the critical range in controlling the rear wheel steering. CONSTITUTION:A motor 31 as a rear wheel steering actuator is driven by the electric signal from a control unit 50, and the automatic steering is executed by driving the rear wheels against the gripping force. The load condition of the motor is presumed by the acceleration or the like of the vehicle while the vehicle is traveling, and if the motor load judges the excessive critical range, the steering control in the direction where the rear wheels are further steered is stopped, and the rear wheel steering angle is kept to the value immediately before the motor load becomes excessive, and the control of the rear wheel steering is re-started after the target rear wheel steering angle becomes not greater than the kept rear wheel steering angle in steering-back.

Title: Brush of flat motor
Inventor: YOSHIOKA KATSUHIRO
IPC: H01R39/38
Filed: 1980-10-23
Abstract: PURPOSE:To prevent twisting or eccentricity between bearings and vibration from occurring, by providing an automatic self-aligning bearing at the bottom of a flush- opening yoke, retaining through a rotor shaft, and forming a rectangular brush  holder. CONSTITUTION:An automatic self-aligning bearing 3 is mounted at the bottom of a flush-opening yoke 1. A rotor 9 is retained by the bearing 3 through a shaft 10. A brush holder 5 is formed by die-cutting a rectangular printed circuit board. Terminals 6 are projected to one side. The holder 5 is fixed at the center of a yoke cover 4. A semiconductor permanent magnet 12 for field is fixed on both sides of it. This reduces the pitch between bearings, the mechanical loss, and the eccentricity due to randomness of dimensional accuracy to a minimum. This also prevents the vibration of the brush holder 5.

Title: Valve device for controlling rope tension
Inventor: SHIINA CHIKASHI
IPC: B63B21/16
Filed: 1985-07-09
Abstract: PURPOSE:To achieve tension control by a simple hydraulic pump in a mooring apparatus or the like by providing a valve housing of a valve device with a control port in which a fluid pressure proportional to the rope tension is generated, a pump port and a tank port. CONSTITUTION:A variable delivery pump 6 is controlled in such a manner that, when the pressure at a pump port 5 exceeds a predetermined value,the delivery automatically approaches 0. When the tension of a rope 1 is small, a spool of a valve device 4 is urged by a spring to connect a control port 3 to the pump port 5, so that a hydraulic cylinder 2 is retracted to impart tension to the rope 1. On the other hand, when the tension is large, the spool connects the control port 3 to a tank port 7, so that the cylinder 2 is protruded to reduce the tension of the rope 1. thus, the rope tension can be controlled by a variable delivery pump with a conventional cutoff device, and the value device can be of simple construction.

Title: Address generating method
Inventor: TAKAHASHI MICHIO
IPC: G06F1/03
Filed: 1978-12-07
Abstract: PURPOSE:To generate two sine-wave cosine-wave signals using sampled values for one period of one signal, by shifting a read start address by the fixed number of sampled values. CONSTITUTION:Memory 21 is stored with sampled values for one period of a sine- wave signal and according to an address signal from address generating circuit 3', sampled values in memory 21 are read out in the fixed order. To obtain sine-wave and cosine-wave signal of a desired frequency, initital-value setting memory 22 changes read start addresses of memory 21. In this way, when a ratio of the desired frequency to the frequency of a signal stored in memory 21 is sent to memory 4, address generating circuit 3' generates address signal S1 and as set values of initial- value setting memory 22 are changed, the desired sine-wave or cosine-wave signal is outputted from memory 21. Therefore, both sine-wave and cosine-wave signals can be obtained by signal memory 21.

Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To realize a favorable printing just after the staring of printing without requiring a complicated constitution and a complex work by a method wherein the supply of a printing paper is stopped before the starting of printing and an ink is oozed out by actuating a printing means under the state that a plate cylinder and a transfer cylinder are brought into contract with each other and, after that, the plate cylinder is turned over once for carrying out an initial action. SOLUTION: A major portion of the cylindrical outer peripheral surface of a plate cylinder 1 is made of a flexible porous body. On the outer peripheral surface of a transfer cylinder 3 arranged adjacent to the plate cylinder, a transfer sheet 3a as an ink acceptor is equipped. The supply of a printing paper 35 from a paper feeding means 31 is stopped before the starting of printing. Then, an ink 27 is oozed out by actuating a printing means under the state that the plate cylinder 1 and the transfer cylinder 3 are brought into contact with each other. After that, the plate cylinder 1 and the transfer cylinder 3 are rotated in at least one turn.  Thus, since the ink 27 can be fully supplied over the whole area of the outer peripheral surface of the plate cylinder 1 and then transferred to the transfer cylinder 3 side, a state fully supplied with the ink is realized just after the start of printing, a resulting in performing a favorable printing since the first sheet of printing.
