Title: Tv signal processor for catv system
Inventor: ARAKAWA AKIRA
IPC: H04N7/10
Filed: 1995-04-28
Abstract: PURPOSE: To provide a simple and inexpensive processor by providing a channel selection section to a 2nd frequency conversion section converting an amplified intermediate frequency signal into a TV signal of a prescribed channel so as to change an output channel. CONSTITUTION: A band pass filter 10 passes a TV signal of a predetermined channel only among signals received by an input terminal 11. The selected TV signal is converted into an intermediate frequency signal by a 1st frequency conversion section 1 and amplified to a prescribed level by an intermediate frequency amplifier section 2. The TV signal amplified by the amplifier 2 is frequency-converted into a TV signal of a desired channel by a 2nd frequency conversion section 3. A channel selection section 4 is connected to a local oscillator 15 of the conversion section 3 and a voltage applied to two terminals 16, 17 is varied to vary the frequency. The signal outputted from the conversion section 3 is selected by a filter 18 and outputted to an output terminal 19.

Filed: 1986-06-04
Abstract: PURPOSE:To always attain stable focus control against external disturbance by adding a signal from a signal generator against external disturbance to an amplifier in a focus servo loop, and using a signal after the addition to adjust the focus servo characteristic. CONSTITUTION:In applying an external disturbance such as vibration, a flaw/ vibration discrimination circuit 22 and a selection circuit 27 throws a switch 21 to the position of a contact (b), and an output of preamplifiers 14, 15 for focus control and the output of a differential amplifier 16 are added at the input of the differential amplifier 16 as proper bipolar signals. Thus, the focus error signal becomes apparently larger to strengthen the servo gain. If a flaw exists, the flaw/vibration discrimination circuit 22 and the selection circuit throw the switch 21 to the position of a contact (c), and in adding an output of the preamplifiers 14, 15 for focus control and an output of the differential amplifier 16 at the input of the differential amplifier 16 as opposite polarity signals, the focus error signal is apparently '0' and out of focused spot is not caused.

Abstract: PURPOSE: To peel unnecessary sections of a sound proof and heat insulation material even if it is a long laminated plate and provide a smooth cutting face of a sound proof and heat insulation material an open face of a metal plate. CONSTITUTION: In a sound proof and heat insulation material peeling device, the round blade 35 of a parting and peeling unit 30 travels (in the direction of a wide arrow mark F) on a boundary line in the sound proof and heat insulation material 53 of a laminated plate 50 by being driven by a travel drive means. This divides the sound proof and heat insulation material 53 into a necessary section and unnecessary section 53b at a boundary line. In the same manner, one of peeling means 20 (scooping claw 37) runs following the round blade 35 along the boundary line and scoops the unnecessary section 53b of the sound proof and heart insulation material 53 from the layer of adhesive agent 52. In the next step, the other one (peeling claw 39) of the peeling means 20 peels the layer of the adhesive agent 52 as a chip 52b from a steel plate 51.  Therefore, parting and peeling motion is conducted smoothly by the round blade 35 and peeling means 20.

Filed: 1980-09-19
Abstract: PURPOSE:To prevent the timer interruption request from leaving waiting for a long time unexpectedly, by increasing the interruption level according to the coincidence circuit of an interval timer, in a timer device for timer interruption. CONSTITUTION:A timer interruption interval is set to a preset register 200 from a program and a comparison circuit 300 compares this with the output 120 of an interval timer 100. When coincidence is detected, the interval timer 100 is set to ''0'' and a roll-over counter 500 is counted up via an AND circuit 400. The counter 500 integrates the number of times of coincided detection at the circuit 300, until any instruction from a clear indication signal 410 is given. If this integrated value is not ''0'', a timer interruption signal is outputted from an OR circuit 600 and the priority of interruption is increased according to the integration value 520.

Title: Magnetic head device
Inventor: SUYAMA HIDEO
IPC: G11B5/31
Filed: 1986-06-05
Abstract: PURPOSE:To sufficiently shorten intervals of tracks to raise the track density by setting the length of a magnetic head for servo in the breadthwise direction of tracks to a value sufficiently shorter than the width of a guard band. CONSTITUTION:A length L of a magnetic head HS for track servo in the breadthwise direction of tracks is set to a value sufficiently shorter than a width WG of guard bands G among tracks T1, T2,... on a magnetic disc 2. Since the magnetic head HS is constituted as an MR type head, a required reproduced output is obtained though the length L in the breadthwise direction of tracks is made sufficiently short, and thereby, the width WG of guard bands can be set to a sufficiently narrow width without taking the length of the magnetic head for servo in the breadthwise direction of tracks into consideration. Thus, intervals of tracks T are sufficiently shortened, that is, the track density is raised.
