Title: System for measuring accuracy of polygonal mirror
Inventor: YAMASHITA NOBUAKI
IPC: G01M11/00
Filed: 1983-10-31
Abstract: PURPOSE:To make it possible to measure the slant angle of the plane of a rotating polygon mirror at every mirror plane relatively and highly accurately, by comparing the interference fringes formed by the reflected light by each mirror plane and the reflected light from the surface of a transmitting member. CONSTITUTION:At the stationary state of a polygon mirror, interference fringes 9 are generated by a specified mirror plane 5b, which is a reference plane. Then the polygon mirror 5 is rotated. When the specified number of rotation is reached, the ON and OFF synchronization of a laser beam 2 is controlled by a light source 1, so that only reflected light 7 from the reference mirror plane 5b and reference light 8 from the surface are projected on a projection plane 10. The timing of said synchronization control is slightly adjusted finely by the same means. Then interference fringes 9' corresponding to all the mirror planes other than the reference plane are measured. Then the difference DELTAtheta in slant angle of each mirror plane with respect to a rotary shaft 5a can be expressed by a formula DELTAtheta (l1-l0)lambda/2l0l1, where l0 is a pitch of the interference fringes 9 and l1 is a pitch of the interference fringes 9'. Thus the slant angles of all the mirror planes with respect to the reference mirror plane can be computed accurately.

IPC: F16H7/08
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To increase an effective capacity of an operating fluid storage chamber, and prevent a delay in supply of an operating fluid to a tensioner at restarting time by lowering an oil level of the operating fluid necessary at restarting time more than an operating fluid supply hole by a partition wall extended downward from an upper side wall surface in the operating fluid storage chamber of a cylinder block. SOLUTION: An operating fluid delivered to an operating fluid storage chamber 38 from an operating fluid delivery hole of a cylinder block 4 flows on the upper side of a partition wall 66, and flows toward an operating fluid supply hole 58 on the under side of the partition wall 66 by bypassing the tip 72. In a hydraulic tensioner, the operating fluid of the operating fluid storage chamber 38 push-advances a plunger by oil pressure of a high pressure chamber supplied from the operating fluid supply hole 58 and force of a spring, and proper tensile force is applied to a timing chain through a swinging body. Since a partition wall 66 in the operating fluid storage chamber 38 lowers an oil level L2 at restarting time more than the operating fluid supply hole 58, an effective quantity of the operating fluid storage chamber 38 can be secured large.

Filed: 1988-08-23
Abstract: PURPOSE:To prevent the dewing and adsorption and to attain the stable writing and reading by selecting the roughness of the outer end protruded part surface of a magnetic head supporting body. CONSTITUTION:A gap forming part 2a of a magnetic head 2 is inserted into the hole of a supporting body 1 and protruded a little from the upper surface of a ring-shaped protruding part 1d and fixed. The surface roughness of surfaces 1f and 1g for a disk 3 of ring-shaped protruding parts 1a and 1b is selected to 0.2 - 0.3S. The disk 3 to rotate at a high speed in the direction of an arrow A is deformed along the unevenness of a supporting body by a negative pressure by recessed parts 1b and 1e and the touch of the magnetic head 2 and the disk 3 is stabilized. The surface of the protruding parts 1a and 1b has a prescribed roughness and when air passes between a protruding part surface and the disk 3, the pressure reduction is decreased and the dewing does not occur. By such a constitution, without the pressure reduction and the temperature reduction to the extent to generate the dewing, the disk can be absorbed and the adsorption of the magnetic disk due to the dewing and the pressure reduction can be evaded.
