Title: Vehicular suspension device
Inventor: HOSOYA HARUYUKI
IPC: F16F9/04
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To prevent the air leak of an air chamber of an air spring by preventing a supporting member of the air spring provided between a beam mounted on an axle case and a car body frame from interfering with the beam. SOLUTION: An air spring 60 is provided between the end part of a beam 24 mounted on an axle base and a car body frame 2. A relief part 82 is formed between the lower end part of a housing part 68 constituting a piston 85, namely the supporting member of the air spring 60 and the beam 24 so that the beam 24 does not interfere with the housing part 68 when the beam is bent-deformed. Thus, the housing part 68 is not subjected to damage even when it collides with the beam 24. Besides, auxiliary air chambers 69 in the housing part 68 which are connected to the air chamber 66 in a diaphragm 63 through connecting holes 73 are kept airtight.

Title: Mechanical descaling device
Inventor: SHIYOUZAKI TAMOTSU
IPC: B21C43/04
Filed: 1994-06-30
Abstract: PURPOSE:To uniformly remove the scale sticking to a metallic wire in follow up to the variation in drawing speed by calculating the required number of twisting revolutions from the drawing speed detected from a drawing speed detecting means and the twist quantity read out of a twist quantity memory means, then rotating a rotating body for generating the twist according to the number of twisting revolutions. CONSTITUTION:The traveling metallic wire 30 is forcibly swivelled around its axis and the twists are generated in the metallic wire 30 by its sufficient toughness, but the scale sticking to its surface hardly has the toughness and, therefore, the follow-up to the twists is not possible and consequently, the peeling force acts between both and the scale is dislodged. A detector 16 detects the drawing speed of the metallic wire 30 imparted with the twists and inputs the drawing speed to a control circuit 17. The control circuit 17 reads out the twist quantity stored in a memory 17b of the twist quantity memory means, calculates the number of the twisting revolutions and controls the number of revolutions of a rotating body 13 for generating the twists.

Abstract: PROBLEM TO BE SOLVED: To excellently photograph a pattern image in a wide area and to accurately perform focus detection in plural areas while simplifying an entire optical system by specifying the respective elements of a light projecting system at the time of photographing a pattern on a subject side. SOLUTION: The pattern 2 illuminated with luminous flux from a light source 1 is projected in directions (three directions) in which one direction (horizontal direction, X direction) is different on a subject surface by three lens parts 11 to 13 constituting a light projecting lens 1. At such a time, the luminous flux is divided in the directions (three directions) different in a vertical direction on the subject surface through a deflection part 4, and projected in nine directions as a whole. As for the state of the projected pattern image; it does not matter whether the projected pattern image is perfectly separated or partially overlapped. The luminous flux is separated by selecting an appropriate prism angle or the separation amount of an optical axis according to the focus detection area of an attached focus detector.  At such a time, the eccentric amount of the lens 1 is kept to the minimum and a projection range is extended by a prism part.

Filed: 1986-06-26
Abstract: PURPOSE:To shorten the time for dressing work by detecting the exhaustion part of an electrode by a detecting mechanism and removing said exhaustion part by a removing mechanism, thus carrying out the high precision work by using one electrode. CONSTITUTION:Since, when the edge surface positioning completion position X3 of an electrode 2 after the completion of working is not same to the edge surface positioning completion position X2 of the electrode 2 before the start of working, it is judged that the exhaustion at that position of the electrode 2 is generated, the present position Z2 in the Z-direction is read by an NC device, and the present position Z3 in the Z-direction at the position X3 is read by the NC device 12. The difference between Z2 and Z3 represents the length in the Z-direction of the exhaustion part of the electrode 2. Then, the electrode 2 is transferred to the upper surface of an electrode 15 for dressing work, and after the completion of the edge surface positioning in the -Z-direction, the electrode 2 is dressiing-worked by the portion represented by the absolute value of the difference between Z3 and Z2, and the exhaustion part of the electrode is removed. Thus, the superior electrode shape can be always obtained, and high precision work is permitted with one electrode, and also the dressing work can be facilitated, and the necessary time can be reduced.
