Title: Discriminating method for recording signal
Inventor: KUBO KANJI
IPC: H04N5/93
Filed: 1985-03-04
Abstract: PURPOSE:To discriminate a signal system recorded already by using a signal converting in terms of frequency a pilot signal to be reproduced into a low frequency signal to form a tracking error signal thereby discriminating the presence of adjoining signals. CONSTITUTION:A difference signal outputted from a balanced modulation circuit 1002 is fed to a tuning circuit 103 extracting a 2fH signal, an output signal of the circuit 103 is detected and rectified by a detection and rectification circuit 104 to output a signal (b). A level 301 shown in a figure (b) is a 3fH signal level so long as the recording and the reproduction are executed at the same system. Thus, in comparing a level 302 sufficiently larger than the level 301 with an output signal 303 of the circuit 104 by a level comparator circuit 105, a signal (c) going to a high level only when the recording system differs from the reproducing system is obtained. A circuit 106 is an automatic discrimination circuit and discriminates the system at recording by discriminating whether or not the signal (c) includes a high level signal.

Abstract: PURPOSE:To prevent the bearing lubrication surface from electric current flowing and prevent the bearing from damage caused by electrolytic corrosion by a method wherein a conductive rubber enclosing plate is mounted on a ball-and- roller bearing and the like used in a motor, then the plate is contacted with both of an inner and an outer ring in the bearing. CONSTITUTION:When an electric voltage loaded between an outer ring 1 and an inner ring 5 of a cylindrical ball-and-roller bearing exceeds the withstanding voltage of an oil film 7 formed on the lubricating surface of a bearing, a discharge occurs on the lubricating surface of the bearing, the bearing is damaged by a scar generated by the discharge. A conductive rubber enclosing plate 6 is fixed to the outer ring 1, one end thereof is contacted with the inner ring 5, thus, a discharging electric current is flowed along a circuit 6 for preventing the damage of the bearing. Thereby, the damage on the lubricating surface of the bearing caused by the electrolytic corrosion can be prevented without providing an insulator and a chemical formation processing on both of the inner ring 5 and the outer ring 1, accordingly, the bearing life can be extremely extended.

Abstract: PURPOSE:To strengthen the rigidity of a panel plate by, after leg-shaped side parts are fixed to both the sides of the front part of the panel plate at a specified obtuse angle, vertically restricting the side parts for making the front part slightly project into a convex shape. CONSTITUTION:A panel plate is composed of a front part 1a having a rib-shaped lip part 1c formed at its front and rear edges and right and left sides 1b having formed a lip part 1a. The faces 1a, 1b are then bent along a bending line A, and an angle made of the faces 1a, 1b is formed into an obtuse angle larger than the angle of the final product by 5-20 deg., and those faces are fixed by welding or the like. In attaching the panel plate, the face 1b is restricted in the state of the final product having no obtuse angle part to make the face 1a slightly project into a convex shape for strengthening the rigidity of the panel plate. Thus even the panel plate being thin in thickness can be prevented from deforming, and, moreover, its weight and cost can be reduced.

Abstract: PURPOSE:To permit the fine screw cutting work having a correct pitch by permitting the grinding feed and the grinding return only by the lead of the tap itself, in a tapping machine equipped with a driving machine for revolving the tap and a driving machine for feeding the tap. CONSTITUTION:In the captioned tapping machine, the rapid traverse in which a tap 12 advances from an original position and reaches a prepared hole of a work and the main-shaft rapid traverse in which the tap 12 is released from the prepared hole and returns to the original position are taken by a feeding driving machine 20 which is represented by a DC servomotor.

IPC: H04Q3/58
Filed: 1987-02-27
Abstract: PURPOSE:To prevent a noise from being heard even if a data leaks into a communication line by transmitting a polling data when a terminal equipment is connected at the head of polling, and transmitting a dummy data to a data signal line when the terminal equipment is not connected there to eliminate a period having no signals. CONSTITUTION:A deciding means 15 decides whether or not terminal equipments 4-6 are connected at a the polling head, and informs the result to a data transmission control means. The data transmission control means, when the terminal equipments 4-6 are connected at the polling head, transmits a polling data, and when not connected, transmits a dummy data so that the period having no signal is not generated on a data signal line. Therefore, data is always placed on the data signal line, any period lacking signals is not generated. As a result, no noise is heared even if a data to be transmitted through a data line leaks into the communication line.

IPC: H04N5/782
Filed: 1991-03-08
Abstract: PURPOSE:To attain normal edit by correcting automatically missing even when a missing CTR pulse exists in a reproduction signal of a VTR. CONSTITUTION:Interrupt generating circuits 9,13 interrupt a microcomputer 11 in the timing of a CTL pulse in a reproduction signal for an edit period from VTR-P1, VTR-R2 at rehearsal. When no interrupt is applied to a microcomputer 11 within 33.3ms, it is discriminated that a CTL pulse is missing and a missing occurrence position is stored in a RAM 16. The microcomputer 11 at the execution of edit corrects the missing of the CTL pulse by deviating the CTL pulse position representing pre-roll pint, IN point and OUT point based on a missing occurrence position stored in the RAM 16 or using synchronizing oscillation circuits 5,8 to interpolate the CTL pulse representing the points.

IPC: G09G3/14
Filed: 1988-02-26
Abstract: PURPOSE:To improve the stability and reliability of a circuit by providing the title circuit with a switching means for operating a light emitting element only by a voltage in a prescribed range lower than a maximum allowable value. CONSTITUTION:A 1st switching means 3 is held in a state disabling a transistor(TR) Q1 when the output voltage of a full-wave rectifier circuit 2 does not reach a prescribed voltage, but when the output voltage of the circuit 2 reaches the prescribed voltage, the TR Q1 is driven and the light emitting operation of a light emitting diode(LED) is allowed. When the output voltage of the circuit 2 reaches a 1st set voltage V1 necessary for light emission, the diode LED starts light emitting operation. On the other hand, a 2nd switching circuit 54 emits the diode LED without operating a TR Q2, but when the output voltage of the circuit 2 reaches a 2nd set voltage, drives the TR Q2 and regulates the light emission of the LED. Consequently, the stability and reliability of the light emission operating circuit can be improved.
