Title: Liquid sealed type vibration controlling device
Inventor: ISHIYAMA TATSURO
IPC: F16F13/14
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To surely provide a large damping force with a simple structure. SOLUTION: Since a limiting passage for a liquid 22 is formed of a limiting passage constituting member 26 consisting of a rigid tubular body arranged on an elastic body, the limiting passage 261 can regularly keep a fixed dimension without being influenced by the elastic deformation of an elastic body 34 in absorption of vibration. Therefore, a large damping force can be stably provided, compared with a liquid sealed type vibration controlling device having a limiting passage formed by simply providing a through-hole 24 on the elastic body 34. Since a dropping-out preventing part 265 from the elastic body 34 is provided on the end part peripheral surface of the limiting passage constituting member 26, the limiting passage constituting member 26 consisting of the rigid tubular body is never easily dropped out from the elastic body 34.  Therefore, the dimension of the limiting passage 261 for the liquid 22 can be regularly ensured.

Title: Angle regulation mechanism for bearing
Inventor: TOKIHISA TAKASHI
IPC: F16C23/08
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To provide an angle regulation mechanism having its very light movement and its long service life by forming the abovementioned mechanism in such barrel type configuration that a bearing main body is fitted in and supported by a hole formed in a case the hole of the case is cylindrical and the sectional surface configuration of the bearing main body is in a circular arc. SOLUTION: A bearing main body is in a barrel type configuration in relation to the cylindrical surface of the inner circumference of a case 2 and according to the principle or rolling of the barrel type configuration, an angle regulation mechanism is placed in its action. Namely, even though any deflection, etc., of a shaft 3 may be generated, a bearing main body 1 and the shaft 3 are changed in their angles around a base point 0 serving as a turning center where the vertical line and an axial line cross each other at the position of the maximum diameter of the barrel type. At this time, in order to cause no prevention against movement of the bearing main body 1, a gap 8 is provided. Therefore, because the bearing main body 1 makes angle regulation inside of the case 1, an applied load is uniformly dispersed to an orbit surface and steel balls 4 inside of the bearing main body 1.  Then, the shaft 3 can be made very light-weighed and can have a long service life.

Title: Density detecting method for copying machine
Inventor: TAKAHASHI MASANOBU
IPC: G03G15/08
Filed: 1989-12-04
Abstract: PURPOSE:To reduce the toner consumption by exposing a simulated original to form an electrostatic latent image at each time of copying operation and repeating the processing to develop the latent image to a toner image and the latent image erasing processing with a prescribed period. CONSTITUTION:The reset signal from a reset circuit 16 and the output signal from a reflective sensor 6 are applied to a microprocessor 17, and the toner replenishing device driving signal from the processor 17 is applied to a driving circuit 18, and the output signal from this circuit 18 is applied to a toner replenishing motor 19. At the time of first and second copying operations, the toner image density is not detected because the electrostatic latent image of a simulated original 9 is not developed to a toner image. Consequently, the original is copied without replenishing toner. The toner image density of the simulated original 9 is detected after the end of the third copying operation, and toner is replenished when the density is reduced. Since it is unnecessary to develop the latent image of the simulated original 9 at each time of copying, the toner consumption is reduced and the burden on a cleaner 7 is reduced.
