Filed: 1978-07-19
Abstract: PURPOSE: To hold a very thin movement effectively to hold precision in a simple structure by pressing up selectively the character reverse face by an inside frame which is pressed up by a reverse cover.  
     CONSTITUTION: The outside circumference part of character board 5 is brought into contact with partition face 1a of side body 1 from the lower direction, and inside frame 4 provided with protrusion 4a on the upper face is brought into contact with the reverse face of character board 5 selectively, namely, partially from the reverse face side of character board 5 so that force is applied to the reverse face of character board 5. Further, reverse cover 2 is arranged and held from the reverse face of inside frame 4 through packing 6 to press up inside frame 4, and the pressing-up force of reverse cover 2 is transferred to partition face 1a through inside frame 4 and character board 5 and is fixed.

Abstract: PURPOSE: To prevent stepping of the force of water by delaying the operation or a specific solenoid valve by a delay time to make the opening timings and the closing timings of respective solenoid valves coincide with each other in the case of simultaneously opening and closing plural solenoid valves provided in parallel. CONSTITUTION: Solenoid valves A to D of 1, 2, 4, and 8L/min flow rates are provided in parallel, and opening and closing of solenoid valves A to D are controlled by a control part 1. When a signal to change the flow rate is inputted to the control part 1, a delay time ΔT of the solenoid valve of a maximum flow rate out of solenoid valves to be opened is calculated, and a valve open signal is first outputted to solenoid valves to be opened. After T seconds, the valve open signal is outputted to solenoid valves to be opened. When ΔT is larger than 0, the open signal is outputted whenΔT smaller than 0, the close signal is outputted when ΔT elapses after the output of the open signal. Thus, stepping is surely prevented.

IPC: G06T7/00
Filed: 1987-04-10
Abstract: PURPOSE:To realize a little influence of the up-down and right-left inclinations of a face at the time measurement and to improve measurement accuracy by specifying an original profile line and feature quantity measurement points as points having individual features such as the forehead, eyes, noise, mouth, and jaw obtained by differentiating the original profile line, and finding feature quantities such as a distance, length, area, and angles. CONSTITUTION:Differential coefficient profile lines f'(x) and f''(x) are generated by differentiating the original profile line f(x) in addition to the original profile line f(x) inputted from a television camera to obtain stable differential quantity measurement points. The differential coefficient profile line f'(x) can be emphasized as to point corresponding the feature quantity measurement points such as a point where the increase or decrease of the original profile line f(x) varies in rate abruptly, a segment where the increase or decrease of the original profile line f(x) is constant in ratio, and a point where the original profile line f(x) neither increases nor decreases. Consequently, when the up-down and right-left inclinations of the face at the time of measurement are slight, feature quantities can be extracted relatively with ease.
