Title: Magnetic head cleaning cassette of video tape recorder
Inventor: KANNO TOSHIYUKI
IPC: G11B23/04
Filed: 1982-09-29
Abstract: PURPOSE:To clean a video head in a picture recording or reproducing state by projecting a lever which is rotated and displaced in relation to a movement of an operating mechanism of a video tape recorder, to the front of a case, and also fitting a pad for wiping the video head to the tip. CONSTITUTION:In a non-operating state, a pin 9 is obstructed from rotating to the left outside by force of a spring 10 since the tip of its lever 8 is made to press-contact with a post 5 being in a non-loading state. When the post 5 starts a loading operation simultaneously with turn-on of an electric power source, the pin 9 rotates counterclockwise to the left outside against elasticity of the spring 10, and also rotates simultaneously a cleaning lever 17 counterclockwise. In this case, since a spring 19 is formed more weakly than the spring 10, the cleaning lever 17 rotates counterclockwise as the pin 9 rotates, and simultaneously, a cleaning pad 16 of the tip contacts along the outside circumferential surface of a cylinder 1, the tip of a rotating video head is made to press-contact by moderate elastic force, and cleaning is executed.

Title: Dielectric filter
Inventor: EGAMI MASANOBU
IPC: H01P1/20
Filed: 1992-06-04
Abstract: PURPOSE:To decrease mis-adjustment when a trimming land is removed in the case of characteristic adjustment. CONSTITUTION:The trimming land 19 for characteristic adjustment is formed nearly in the center of a conductor pattern 2. Comparing th case that the trimming land 19 is formed to an end part (in a conventional case) with the case that it is formed almost in the central part in the case of trimming by the same amount, the change in a resonance frequency f0 is larger when the trimming land 19 is formed to the end part. That is, the change in the resonance frequency f0 by trimming is less when the trimming land 19 is formed almost in the central part. Thus, a very small trimming is implemented by forming the trimming land 19 in the central part of the conductor pattern 2. Furthermore, no change is observed in no load Q0 and the chipping or the crack of a dielectric board 1 is reduced.

Abstract: PURPOSE:To obtain a satisfactory recording performance by adding an output signal of a differentiating circuit to a signal obtained by attenuating an input digital signal, and setting it to a recording waveform for giving a diamagnetic field immediately after data inversion by a waveform compensating circuit of high frequency emphasis using a delay element. CONSTITUTION:A digital signal inputted by prescribed amplitude is differentiated, added to the digital signal inputted by prescribed amplitude, and also, the added signal is added to a signal obtained by delaying the added signal, and thereafter, a current is supplied to a magnetic head 5 by a constant-voltage driving circuit 11. Accordingly, a means 9 for differentiating the digital signal, and adding the digital signal inputted by prescribed amplitude becomes a low frequency boost circuit, and the current supply to a magnetic head of a low frequency is compensated. Also, a means 10 for adding the added signal to the signal obtained by delaying the added signal becomes a high frequency emphasis circuit, and a non-linear distortion at the time of recording is compensated. Moreover, an output capacity is reduced by the constant-voltage driving circuit 11, and a further wide band conversion can be executed. In such a way, a satisfactory recording performance scarcely having the non-linear distortion is obtained.
