Title: Automatic gain control circuit
Inventor: ARAFUNE YASUNARI
IPC: H03G3/30
Filed: 1980-03-19
Abstract: PURPOSE:To control always the synchronizing signal level to a fixed level, by detecting the amplitude of the synchronizing signal to control the gain of the automatic gain control amplifying circuit and by detecting the peak value of pattern components to control the amplitude of the synchronizing signal. CONSTITUTION:The video signal applied to input terminal 22 is not only led out to output terminal 24 through synchronizing signal amplitude control circuit 22 and automatic gain control amplifying circuit 23 but also applied to synchronizing separating circuit 25 and synchronizing leading edge clamp circuit 26. The synchronizing signal separated by circuit 25 is applied to circuit 26 and pulse delay circuit 27. The leading edge of the synchronizing signal is clamped with a prescribed DC level in circuit 25, and the output is applied to synchronizing detecting circuit 28 and peak value detecting circuit 29. The synchronizing signal delayed by circuit 27 is applied to circuit 28 as sample pulse a1, and the synchronizing signal detection output is applied to circuit 23 from circuit 28. Meanwhile, circuit 29 detects the peak value of pattern components and applies it to circuit 22. Consequently, the output signal at output terminal 24 is output after the ratio of pattern components to synchronizing components of the video signal is corrected stably, even if this ratio is changed.

Abstract: PURPOSE:To confirm communication charge for each communication line by recognizing an operating line at communication, managing the communication charge corresponding to the operating line calculated for each communication and preparing a communication charge management report corresponding the communication charge and the operating line. CONSTITUTION:A charge table 10 uses a time per one communication (talking) call unit to store it as the charge data in a form of a table.

The communication charge in the charge memory 12 is managed by a system control section 2 in a retrieved form based on the line type, communication date and communication destination or the like. Thus, the communication charge for the communication lines L1, L2 is confirmed from the management report.

Title: Dc stabilized power circuit
Inventor: SAITO HIROYUKI
IPC: G05F1/56
Filed: 1989-02-15
Abstract: PURPOSE:To minimize the difference between the input and output voltage levels by turning on a switching circuit when the load side is short-circuited or set in a short circuit state and allowing both ends of a differential circuit to be short-circuited. CONSTITUTION:A switching circuit 7 inserted in parallel to a differential circuit part 4a is provided with a transistor TR2 which is set in an OFF state in a normal working state. When a load connected to an output terminal 2c is short- circuited or set in a short circuit state together with the potential of an output terminal 2c dropped less than 1Vf (drop voltage in the (a) forward direction between base and emitter), a TR2 is turned on and both terminals of the circuit 4a are short-circuited. Thus the circuit 4a stops its working and produces no output any more. As a result, the insertion of a protection resistance is not required to an output stage. Then the difference between the input and output voltage levels is minimized.

Title: Production of magnetic head
Inventor: SUZUKI KATSUMI
IPC: G11B5/31
Filed: 1986-02-21
Abstract: PURPOSE:To stably form the same size and shape of a photomask for exposure or the objective size and shape on different steps without residual films by using the plural photomasks for exposure and making multiple exposure. CONSTITUTION:Exposure is divided to two parts; part A and part B in the case of forming the photoresist patterns on the different steps. Adequate over exposure is executed in the part A as the resist thickness is larger in said part then in other parts in the stage of coating the photoresist and the residual film of the resist is liable to be formed in the stage of exposing and developing. The resist on the step is in tight contact with the photomask during the hard contact exposure and therefore, the step is neglected at all and the resist is exposed purely at the adequate exposure for thickness of the resist coated on the step. The resist is exposed at the adequate exposure at which the objective size and shape are obtd. even in the other case in which the photomask and the resist on the step are not in tight contact with each other. The resist pattern having the same size and shape as the size and shape of the photomask for exposure or the objective size and shape is thereby formed stably on the step without residual films in the parts D, E.
