Title: Controller for astronomical telescope
Inventor: TAKEGAHARA HIDEFUMI
IPC: G02B23/16
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption and to reduce the heat generation of step motor by providing a block, in which the current of motor coil is more than a reference value, and a block, in which that current is less than the reference value, inside one excitation step of motor. SOLUTION: Based on a reference signal pulse sent from a reference signal oscillator 5, an exciting signal generator 7 prepares an excitation sequence and outputs a current value and an instruct signal for the direction of current from this excitation sequence to A driver 4a and B driver 4b. According to the instruct signal, the A driver 4a lets a current flow to a coil 3a and the B driver 4b lets a current flow to a coil 3b.  The rotation torque of step motor 1 is in the proportional relation with the current of motor coil and while defining a current value sufficient for driving a warm type decelerator as a reference value, the current value of motor coil is made higher than the reference value only at the moment, when a rotor 2 of step motor 1 is rotated for one step, but the current value is made lower than the reference value after one-step rotation of rotor 2 so that the rotation torque of rotor 2 can be kept higher than a fixed value and an average coil current can be reduced.

IPC: G11B23/087
Filed: 1995-02-27
Abstract: PURPOSE: To constitute a tape guide which comes into contact with a tape while the tape is run in the length direction in a state where the tape is slid on the guide and controls the running position of the tape in such a way that the guide can be manufactured at a low cost, has an excellent wear resistance, and does not damage the tape. CONSTITUTION: Thin film layers having wear resistances and lubricating abilities are formed on the surfaces of at least control sections 5a and 5b of a tape guide 4 which comes into contact with a tape while the tape is slid on the sections 5a and 5b. Because of the thin film layers, not only the wear resistance of the guide 4 can be improved, but also the damage of the tape can be prevented by reducing the sliding resistance of the guide 4 when the tape is run. In addition, the main body of the guide 4 can be formed of an inexpensive plastic, because it is not required to take the wear resistance and lubricating ability of the main body into consideration. It is preferable, in addition, to form the thin film layers of a conductive material. The most suitable thin film layers are composite plated layers.

Title: Buffer type gas-blast circuit breaker
Inventor: AOYANAGI HIROKUNI
IPC: H01H33/53
Filed: 1990-02-21
Abstract: PURPOSE:To reduce a size of a buffer type gas-blast circuit breaker and enhance reliability in full consideration of strength of an electric field inside a container against impurity such as a floating metal foreign material by deviatedly arranging shields around a breaker contact portion and a resistant contact portion. CONSTITUTION:At the time of closing, movable poles 22, 26 for closing resistance contact are closed, and concurrently, a closing resistance 29 is inserted into a circuit for a predetermined period. Upon closing of movable electrodes 1, 10 for main contact inside an arc extinguish chamber, a current is not supplied to the resistance 29. Shields 30, 31 are disposed around a shield contact portion 19 and a resistance contact portion 20 to surround the movable poles, respectively. An insulating cylinder 32 between the poles is interposed between the shields. The shields 30, 31 are deviatedly arranged upward of the central axis of a container 33 so that a distance between each shield and the inner surface of the container is longer at the upper portion thereof than at the lower portion thereof. Consequently, the distance between the upper inner surface of the container and each shield 30, 31 is shortened, thus reducing the whole size of the container 33 so as to downsize a breaker.
