IPC: G01D5/165
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To maintain a state that a brush is in contact with a resistor, and prevent contact failure by installing a wiper in parallel to a brush sliding on a resistor in accordance with rotation of a rotary shaft, and eliminating foreign matters attaching on the resistor with the wiper, in accordance with rotation of the rotary shaft. SOLUTION: A wiper 14 is installed so as to be positioned in the rear of a brush 6 when a throttle valve opens. The number of lines 15, 16 constituting the wiper 14 is set as, e.g. twice the number of lines 11, 12 constituting the brush 6. The outer diameter of the respective lines 15, 16 of the wiper 14 is set as about one-half the lines 11, 12 of the brush 6. The respective lines 15, 16 are installed in a long range in the rotating direction as compared with the respective lines 11, 12 of the brush 6. When the throttle valve opens and closes, the brush 6 revolves while sliding on an intermediate arcuate part and an outside arcuate part. Resistance values of he intermediate arcuate part and the outside arcuate part which are shorted by the brush 6 are changed, and an output corresponding to the opening of the throttle valve is obtained.

Filed: 1990-05-19
Abstract: PURPOSE:To secure the loose rotation of a work roll corresponding to the specific control speed of the work and to prevent the slack, by mounting a braking abutment plate on the peripheral face of the work roll. CONSTITUTION:A work roll (x) supported on the loose rotating roll shaft 25 of an uncoiler 20 is rotated with its being pulled by the feed driving force of a wide belt sanding machine 1 and recoiler 50, but is loosely rotated excessively by the force of inertia thereof and this becomes the cause of the slack of the work W between the wide belt sanding machine 1 and uncoiler 20. In this case, a braking abutment plate 32 is mounted on the peripheral face of the work roll (x) and so the excessive loose rotation is checked and the slacking is prevented with the loose rotation of the work roll (x) corresponding to the driving control speed of a work (w) being secured.

IPC: G01V9/00
Filed: 1985-06-14
Abstract: PURPOSE:To detect and stop a moving body at the same time by providing the 1st and the 2nd piezoelectric elements, and exciting one element at a specific frequency and providing the other with an output terminal through which a voltage signal oscillated at the specific frequency is led out. CONSTITUTION:The piezoelectric elements 12 and 20 are arranged at slight distance. When the moving body moves forth and collides against an arm 10a in a Y direction, the arm 10a rotates clockwise as the movement body advances. When the element 12 strikes the element 20 and is pressed, the forward movement of the moving body is stopped by the reaction from a fixed part 18. Simultaneously, the vibration of the element 20 is transmitted to the element 12 and a voltage signal of frequency is therefore generated between electrodes 13 and 14, led to an amplifier 17 through electric wires 15 and 16, and amplified and outputted. Further, the arrival of the moving body is known by monitoring the output of the amplifier. The vibration amplitude of the element 20 is extremely small, so the moving body is stopped and detected at the same time without any time difference.

Thus, the play-still reproduction is obtained quickly without the need of framing as a conventional device. Moreover, no longitudinal and lateral fluctuation of the pattern caused by framing takes place and a stable still pattern is obtained.
