Title: Motor controller
Inventor: TANAKA HIROICHIROU
IPC: H02P7/292
Filed: 1977-09-22
Abstract: PURPOSE: To dicide wether it is the abnormality at load side or at controller side through logic circuit, when the speed or the torque of motor varies, by deciding wether these varying polarities are same with varying polarity of motor current.  
     CONSTITUTION: The speed of DC motor 10 is controlled by the power supplied from thyristor controlled power source 11. When the motor speed varies abruptly due to the abnormality at load side, current in differential amplifier 19 increases to produce positive output signal while the amplifier 20 produces nigative output signal, and AND gate 22 functions to produce a signal on terminal b. When a abnormality occurs at controller side both output signals from amplifiers 19, 20  become positive, and AND gate 21 functions to produce output signal on terminal a

IPC: B41J2/025
Filed: 1980-08-20
Abstract: PURPOSE: To stabilize printing, by using a particular resonance frequency for an electrostriction vibrator exciting the ink in a printing head, and also by exciting the electrostriction vibrator at the electric excitation frequency.  
     CONSTITUTION: The electrostriction vibrator 2 is set to resonate at a frequency 3f 0  which is three times as high as an exciting frequency f 0 . As the quality of a material for the electrostriction has a frequency constant to be determined by the component, a quotient l is obtained by dividing this constant by a resonance frequency, that is, to be calculated by the equation (where, K is a constant; Hz a frequency; m a mass of an electrostriction vibrator), and in the case of a thickness sliding oscillation, by selecting the aforementioned l for a width of the electrostriction vibrator 2 (in the case of a diameter-wise oscillation, however, it is to be selected in the direction of diametral thickness), it is possible to resonate the electrostriction vibrator 2 at a frequency which is three times as high as the excitation frequency. If an excitation is given, in this manner, at a frequency which differs in the neighborhood of the resonance frequency, the electrostriction vibrator oscillates even at the resonance frequency, and it is possible to easily given an excitation containing third higher harmonic.

Abstract: PURPOSE:To obtain invariably optimum slice levels even when the DC level of a signal varies, by providing two slice levels higher and lower than the center of the signal level and adjusting the slice levels automatically on the basis of the time width of a signal level exceeding the slice levels. CONSTITUTION:A video signal (V) is sliced by the 1st and the 2nd comparators 11 and 12 at the 1st and the 2nd slice levels E1 and E2 to obtain digital signals S1 and S2.

Filed: 1986-05-21
Abstract: PURPOSE:To enable a device to properly agree with respectively contrary needs, that is,long-time utility and maneuverability, by forming new joint parts except the part where a storage battery is jointed. CONSTITUTION:A part where a storage battery is jointed with a camera-fit type VTR (device) 6 is formed in the same structure as a joint part B. Therefore, a joint part A of a storage battery 1a is coupled with the part where the storage battery is jointed with the device 6. In this example that one storage battery is jointed, the device 6 can be usdd only for a short time, however, its small weight enables photographing to be with maneuverability. If successive long-time utility rather than maneuverability in photographing is wanted for it by a user, the joint part A of another battery 1b is jointed with the joint part B which is formed at the rear surface side of the storage battery 1a. In case of much longer use being wanted, another storage battery 1C is jointed.

Filed: 1977-09-26
Abstract: PURPOSE: To automate inspection by fiber scopes and ultrasonic probes by disposing extensible columnar expansion units at four corners and each side of a parallelogram, integrating these expansion units and subsequently repeating extension and contraction operations.  
     CONSTITUTION: Expansion units 11 thru 14 constituting the scanning head are disposed at four corners of a parallelogram and 15 thru 18 at each side thereof. These are elongated or contracted in their axial directions by the control signals from the outside. The expansion units 11 thru 14 in an elongated state push their top and bottom end parts to the parallel plates 19, 20 which constitute the narrow part to be scanned. In a contracted state, they contract to a length sufficient for moving by clearing the undulations on the inside surfaces of 19, 20. The elongation and contraction strokes of the expansion units 15 thru 18 are determined according to the required position resolution of the scanning head. As the elongation and contraction operations are subsequently repeated, the scanning head moves in the arrow 10 direction. Hence, if the detector such as fiber scope, etc. is fixed to this head, the narrow part may be automatically scanned with the detector
