Title: Clock generating circuit
Inventor: IWASE SEIICHIRO
IPC: G06F1/12
Filed: 1989-11-27
Abstract: PURPOSE:To adjust the clock frequency by constituting a ring oscillator formed by a gate circuit having a delay corresponding to a gate delay of a clitical path for determining an operation threshold in an IC, as a clock generating circuit in the IC, and controlling a power supply voltage of its oscillator. CONSTITUTION:A ring oscillator is constituted of a gate circuit having a delay corresponding to a gate delay time of a path in which a gate delay in an IC becomes maximum, that is, a clitical path. This ring oscillator is incorporated to the IC 5 as a clock generating circuit 6. In such a state, a frequency of a clock is adjusted due to a fact that a power supply voltage supplied to the ring oscillator is controlled. In such a way, the frequency of the clock can be adjusted, an optimal frequency can be selected, and a margin of a period of the clock against the date delay can be set to a necessary minimum and optimal state.

Title: Rotary encoder
Inventor: OKUYA NORIO
IPC: G01D5/36
Filed: 1990-11-13
Abstract: PURPOSE:To provide a high resolution encoder capable of coping with high speed rotation by a method wherein a guide plate approximately in the same shape as that of a stationary slit plate is located to a detector between a light source and a rotary slit plate so that it is positioned facing the stationary slit plate with the rotary slit plate located therebetween and serving as an symmetrical plane. CONSTITUTION:A hollow shaft 1 is rotated at a high speed through rotation of a shaft 2 to be measured, a slit plate 4 is rotated through a support flange 3, and a rotation position is detected by a detector 8 with high resolution. Since the detector 8 detects the bright and shade fringe of a beamform slit projection image through a laser system, a wide gap is provided between the rotary slit plate 4 and a stationary slit plate 12 to effect reliable detection of a position. Thus, by a guide plate 14 approximately in the same shape as that of the stationary plate 12 between a collimator 11 and the rotary slit plate 4, pressures on both sides of the rotary slit plate 4 are offset with each other, and deformation of the slit plate 4 is prevented from occurring. By making a distance between the plates 4 and 14 equal to a distance between the plates 14 and 4, fatigue rupture is also prevented from occurring, and a high resolution encoder capable of coping with high speed rotation is provided.

Title: Harmonic compensator
Inventor: OGAKI YUJI
IPC: H02M1/12
Filed: 1992-11-18
Abstract: PURPOSE:To improve the compensation rate of a harmonic current by equipping this harmonic compensator with an estimating circuit, which estimates the phase delay, and a limiting circuit, which shapes an overshoot current command by the estimating circuit. CONSTITUTION:An estimating circuit 6 and a limiting circuit 7 are added in a harmonic detecting circuit 1. The estimating circuit 6 is provided at the rear stage of a coordinate converting circuit 5, which has detected the current command, and further the limiting circuit 7 is provided at its rear stage. The estimating circuit 6 compensates the delay in detection of a failure current or the sampling delay due to digital operation to operate the output current command. Moreover, the limiting current 7 suppresses the overshoot of the output waveform by the estimating circuit 6. Accordingly, the vibration by the overshoot of the output waveform at detection of higher-order harmonic can be prevented.

Title: Bus connector
Inventor: KOYANAGI OSAMU
IPC: H02G5/08
Filed: 1993-12-08
Abstract: PURPOSE:To miniaturize and shrink a bus vessel while facilitating assembly by displacing the positions of each connecting section in a plurality of buses in the longitudinal direction of the buses. CONSTITUTION:The places of the connecting sections 10, 11, 12 of three-phase buses 7, 8, 9 supported to bus vessels 1, 2 by insulating post spacers 6 are displaced relatively in the longitudinal direction of the buses 7, 8, 9. That is, the positions of the connecting sections 10, 11, 12, to which electric fields are easier to concentrate than the buses 7, 8, 9, are displaced relatively in the longitudinal direction, thus relaxing the electric fields among each connecting section 10, 11, 12. A flange section 13 dividing the vessels 1, 2 is mounted within a range that the connecting sections 10, 11, 12 are placed, thus facilitating the visual inspection of the appearance, etc., of the connecting sections 10, 11, 12 from the outside of the flange section 13 at the time of assembly. Accordingly, a distance between a pair of the vessels 1, 2 and an interphase distance are shortened that is, the bus vessels 1, 2 can be miniaturized and shrunk-while assembly can be facilitated.

For example, the rod material 12 is a plastic rod material having a circular section with the total length of 160 cm to 230 cm both inclusive, and it has elasticity so that in a swing, it is moderately bent. The grip 13 is formed similarly to the grip of a golf club. The rod material 12 may be formed by large and small rod materials, whereby one is freely put in and out of the other to be easily carried. Thus, a practice tool by which in a swing, air resistance is bodily sensed can be obtained.
