Title: Digital control method for synchronous motor
Inventor: KAKE SHINOBU
IPC: H02P29/40
Filed: 1991-03-13
Abstract: PURPOSE:To provide a digital control method for synchronous motor, to be employed in industrial robot or machine tool, in which resonance with mechanical system is suppressed. CONSTITUTION:A decision is made that a mechanism system is vibrating transiently or continuously if the difference between positive and negative maximum values of sine wave current flowing through a synchronous motor 1 exceeds a predetermined value when the natural vibration frequency band of the mechanism system matches with a speed feedback value, and then the gain to be employed in the operation of speed control loop is regulated. Consequently, the mechanism system connected with the synchronous motor can be controlled stably without causing transient or continuous vibration even when the natural vibration frequency band of the mechanism system connected with the synchronous motor matches with the speed feedback value.

Title: Disk drive device
Inventor: IIDA MICHIHIKO
IPC: G11B19/12
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To rapidly discriminate a recording layer without a sensor mechanism at a disk loading time, etc., by discriminating a first recording layer and a second recording layer having a track pitch narrower than the same of the first recording layer according to whether or not a traverse signal is obtained in the state in which a disk surface is irradiated with a laser beam of resolution corresponding to the first recording layer to be focused nearly. SOLUTION: An optical disk 1 has a CD layer recording the CD data as the recording layer and/or an HD layer recording the HD data having higher definition than the CD data. At a recording layer discrimination operational time, a CD reproducing mode for reproducing the CD layer is set, and an objective lens 34 is moved from the farthest position of the optical disk 1 surface to the nearest position. At this time, it is discriminated that when the traverse signal (intensity modulation as tracking error signal TE) is obtained in the position equivalent to a focus drawing range, it is the CD layer, and when the traverse signal isn't obtained, it is the HD layer.

Title: Flicker elimination circuit
Inventor: HABARA EIJI
IPC: H04N5/243
Filed: 1987-03-04
Abstract: PURPOSE:To eliminate flicker by obtaining a difference between a sampling video signal in the rate of once per field and a video signal sampled in the rate of once per several fields and applying automatic gain control to make the difference zero. CONSTITUTION:A signal is sampled in the rate of once per field by a sampling circuit 7 and sampled in the rate of once per 3 fields by a sampling circuit 9. Then the resulting signal sampled at a rate of once per field and the resulting signal sampled at the rate of once per three fields are given to a differential amplifier 11. Then the difference is fed back to AGC buffers 1, 27 via an up- down counter circuit 13 and the gain is controlled so that the output signal of the differential amplifier 11 is made zero. Since the sensitivity difference is adjusted at a period of 3 fields, the flicker by a beat caused at the 3 field period is eliminated.

Title: Detector for decrease in capacity of storage battery
Inventor: TANAKA AKIFUMI
IPC: G01R19/165
Filed: 1981-04-01
Abstract: PURPOSE:To turn on a pilot lamp by detecting an electromotive force, which varies proportionally with the specific gravity (capacity) of an electrolyte, dropping to the extent that it is judged there is not capacity when a battery is unloaded, or a discharging voltage droppint down to the minimum voltage of load operation when loaded. CONSTITUTION:In case of a car storage battery, when its electromotive force drops to 12V (electrolyte specific gravity; 1.160), an engine becomes difficult to start. When a voltage during discharge drops to about 7V, the engine also becomes hard to start. Therefore, when a constant voltage element of 11V is employed, the 12V electromotive force of the unloaded storage battery develops a 1V voltage between points A and B, and between points and B and C voltage  is set to the 0.6V forward drop of a transistor, etc., in an amplifying circuit 8, so that a pilot lamp 9 turns on and off at 12V. Consequently, a decrease in the capacity of the storage battery is detected without reference to whether the battery is loaded or not, knowing the degree of the life of the battery from the lighting state of the lamp.
