IPC: G11B21/08
Filed: 1986-04-01
Abstract: PURPOSE:To attain smooth feeding operation at a fast forward and to suppress generation of noise by forming a ridge between adjacent slots on a curved face. CONSTITUTION:The curved face processing such as barrel, sand blast processing or paff polishment is applied to a slot G of a screw shaft 20, projecting ridges I existing between adjacent slots G are eliminated to form a smooth curved face J. A flat part H around the projected ridge I caused on a screw shaft 20 is eliminated more or less by the curved face processing, and in forming 10 slots G, if a flat face H of nearly 18-19 deg. at the center remains with respect to rotary angle 36 deg. of one slot G, no effect is given to the stop operation of a coupler 23. At the time of the tip 23b of the coupler 23 moves from one slot G to the other slot G, it is moved very smoothly and the generation of a kind of shock or torsion between the coupler 23 and the slot G due to the override onto the projecting ridge I formed between the slots G is suppressed.

Abstract: PURPOSE:To perform a pressure resistance test without making the water pressure of a hydraulic pump higher than testing pressure, by connecting a large number of high pressure hoses from the hydraulic pump in parallel to pressurize the same and providing a special valve to each of the high pressure hoses on the outlet side thereof. CONSTITUTION:A large number of high pressure hoses 41-4n are connected from a hydraulic pump 1 in parallel and the detection of the non-piercing hose is performed on the outside side of each of the high pressure hoses 41-4n through a special valve. For example, when the first high pressure hose 41 is a non-piercing product, the pistons of the special valves 131-13n are operated and the pressure from the connection hose 5 of the high pressure hose 42 does not communicate with a pressure outlet 22 and, therefore, a pressure switch 7 is not operated. When the high pressure 42 is pierced, the pressure from the pressure inlet 20 on the upstream side reaches the next valve, and when all of the high pressure hoses are not non-piercing products, the pressure switch 7 is finally operated by the repetition of the above-mentioned operation. After a pressure resistance test, the seal jigs 3b1-3bn of the high pressure hoses on the outlet side thereof are detached and the high pressure hoses are closed on the side of the hydraulic pump and compressed air from an air compressing side is blown in a state of parallel arranged pipings to make it possible to remove moisture at once.

Title: Chrominance signal motion detecting circuit
Inventor: TAGUCHI YUTAKA
IPC: H04N9/78
Filed: 1989-03-23
Abstract: PURPOSE:To obtain an accurate motion detection output as to each picture element even when the absolute value of the difference between two frames of two color difference signals differs in hue by outputting the maximum value among absolute values of two-frame differences between two adjacent color difference signals as a motion detection signal. CONSTITUTION:A time-base multiplexed signal S4 is inputted to a one-sample delay circuit 315. The output signal S5 of the one-sample delay circuit 315 and the output signal S4 of an absolute value circuit 313 are inputted to a maximum value selecting circuit 316, which selects a larger output signal between both the output signals S4 and S5, so that the motion detection signal S6 is outputted to a terminal 314. Thus, even if the absolute value of the two- frame difference of one color difference signal and the absolute value of the two-frame difference of the other color difference signal differ in hue when one body moves, those absolute values are compared and the maximum value is outputted as the motion detection signal, so the accurate motion detection output is obtained.

Abstract: PURPOSE:To generate an optional optical path difference by eliminating the parallel movement of an emitted light to keep one parallel plane mirror away from the other to the position as far as mechanical conditions permit. CONSTITUTION:The rotation angle of a rotary plane mirror 13 is changed synchronously with the movement of a moving mirror 11 out of a pair of parallel plane mirrors 11 and 12, which generate a change of optical path length, to make a light incident to the center of a rotary plane mirror 14. If the light is reflected three times by the mirror 11, the distance between a virtual image 24 of the mirror 14 generated by mirrors 11 and 12 and the mirror 14 is six times as long as a length l between mirrors 11 and 12. When the mirror 13 is so rotated that the reflected light of the mirror 13 is made incident to a center 32 of the image 24, the reflected light is made incident to a center 31 of the mirror 14. The position of the displaced mirror 11 is indicated by broken line 11', and the distance between a virtual image 25 of the mirror 14 in the position of the mirror 13 and the mirror 14 is six times as long as a length l' between mirrors 11' and 12. In this case, the light is made incident to the center 31 of the mirror 14 also. When the quantity of displacement of the mirror 11 and the rotation angle of the mirror 13 are determined in this manner, the light is made incident to positions 26-30 similarly.
