IPC: F02M41/14
Filed: 1995-08-08
Abstract: PROBLEM TO BE SOLVED: To prevent generating injection inferiority of an injection pump based on generating foreign matter of cutting chip or the like by improving sealability of a hydraulic timer device, and facilitating assembly manufacture, in the hydraulic timer device for a distributor type fuel injection pump. SOLUTION: A slide pin 58 of transmitting a moving amount of a timer piston 60 to a cam ring 24 is provided in a cavity 65 formed between the first/ second cylinder liner 62, 63 press fitted to a timer housing 56. In the cavity 65, moving the slide pin 58 is permitted. Consequently, without work forming a spot facing hole part in the cylinder liner consisting of wear resistant work difficult material, the permitting cavity 65 for moving the slide pin 58 can be easily formed when assembles a timer. By forming the second cylinder liner 63 into a bag shape, fuel is prevented from leaking to the outside from this bag-shaped part in the inside of the cylinder liner, so as to prevent corroding the timer housing 56.

IPC: G03G15/04
Filed: 1983-10-27
Abstract: PURPOSE:To make the copy speed high accelerating and decelerating an optical running body with a solenoid provided independently of a driving mechanism of the optical running body. CONSTITUTION:A guide bar 28 consists of a magnetic body such as a steel bar or the like, and a solenoid 42 is arranged between sliding bearings 43 and 43 in a slide block 26 of the first optical running body 19. The running body 19 is charged in the advance direction and is accelerated if a current is flowed to the solenoid 42 when the running body 19 starts going, and the running body is charged in the direction opposite to the advance direction and is decelerated if a current is flowed to the solenoid 42 when scanning of an original is terminated. Therefore, the running body 19 and the second optical running body 22 interlocking with this running body 19 are accelerated to a prescribed speed in a short time at a going start time. Further, since the solenoid 42 is provided independently of a driving mechanism 32, an impact load does not act upon the driving mechanism, and a heavy load does not act a driving motor temporarily.

Title: Magnetic disk
Inventor: UMEZAKI MITSUMASA
IPC: G11B5/82
Filed: 1989-08-05
Abstract: PURPOSE:To lower the effective floating height of the disk and to improve the recording density by providing a protective layer in the contact start-stop (CSS) region of a thin film type magnetic recording layer without providing this layer in a data region. CONSTITUTION:Information recording is executed by a Co alloy layer 5 in the same manner as heretofore and a Cr layer 4 controls the magnetic characteristics of the Co alloy layer. A carbon layer 61 is intended to prevent the wear of the Co alloy layer and is provided only on the surface of the CSS region. The magnetic head comes into mechanical contact with a magnetic disk at the time of CSS. The head and disk are brought into smooth contact with each other by the lubricating effect of a carbon layer 61 in the CSS region, by which the wear on the surface of the Co alloy layer 5 is prevented and the reliability is enhanced. Since there is no carbon layer 61 in the data region, the distance between the head and the Co alloy layer 5, i.e. the effective height is lowered and the recording density is correspondingly increased.
