Title: Clamping circuit
Inventor: TANAKA SEIICHI
IPC: H04N5/16
Filed: 1987-09-08
Abstract: PURPOSE:To control the DC level of a luminance signal or a conjugated video signal even when a synchronizing signal can not be separated, by varying the DC level so that the target value of clamping level and an output from a switching means coincide with each other. CONSTITUTION:The leading value on the synchronizing signal side of a conjugated video signal in a regulate period so that at least one or more synchronizing signal is included is included, is detected, held, and updated, however, in case a horizontal synchronizing signal HD is not separated, the DC level of an input conjugated video signal is varied so that said value and a clamping level coincide with each other, and thus the DC level at the leading end of a synchronizing signal is controlled to be constant. Since said detection of the leading value on the synchronizing signal side is executed after subjecting an input conjugated video signal to a low-pass filter 23, the difference between said value and a true synchronizing signal leading value caused by high frequency noise component can be eliminated. As a result, even when a horizontal synchronizing signal is not separated, the DC level of an input conjugated video signal can be controlled.

Title: Thin film forming device using rotary cathode
Inventor: SUZUKI KOICHI
IPC: C23C14/34
Filed: 1988-09-09
Abstract: PURPOSE:To form a coating film by appropriately rotating a slender cathode having a polygonal section and on which different targets are fixed on each face for sputtering, and depositing the particles generated from the targets on a substrate arranged on the opposite side of the targets. CONSTITUTION:The target 30 and the substrate are opposed to the high-density sheet plasma 31 of an arc discharge, and the target 30 is negatively charged with respect to the plasma 31. As a result, innumerable ions can be taken out in the target direction, and high-speed sputtering can be realized. Since sputtering is then carried out with the arc-discharge plasma current as the ion source, a film can be formed at a sufficiently high speed even if the target 30 of simple shape is used. Accordingly, the cathode 1 having a polygonal section and on which the targets 30 of simple shape are fixed on each face can be used as the rotary cathode.

Title: Brake control method
Inventor: OSHIRO HIROSHI
IPC: B60T8/1766
Filed: 1999-08-10
Abstract: PROBLEM TO BE SOLVED: To prohibit transfer to brake control due to falling-in of wheels when passing through a step difference by allowing antilock brake control or braking force distribution control only when the whole wheels show a deceleration tendency. SOLUTION: A control device has various conditions for transferring to antilock brake control. For example, wheel deceleration variations C1, C2, C3, C4 are determined on respective wheels (S23). There use the fact that the whole wheels do not decelerate when the wheels pass through a step difference. Next, whether or not a slip rate and deceleration exceed a prescribed slip rate threshold value and a deceleration threshold value is investigated (S24, S25). When these conditions are satisfied, permission to transfer to an antilock brake control mode is given. Thus, a control area of an ordinary brake is expanded, and reduction in braking force is retrained. Braking force distribution control in rear wheels can similarly enhance a frequency of the braking starting timing when performing control start prohibition determining processing.
