Title: Method of pulling into synchronism
Inventor: SUZUKI MITSUHIRO
IPC: H04L7/08
Filed: 1990-06-21
Abstract: PURPOSE:To pull-in frame synchronization in a short time by continuing the accumulation which judges the acquisition of frame synchronization even after the occurrence of cycle slip without canceling the accumulation due to the occurrence of the cycle slip. CONSTITUTION:An adder circuit 14 obtains a 1st accumulating value, in which an initial value is started from 0, 1 is incremented when a unique word is detected at the prescribed location of a frame and 1 is decremented when the unique word is not detected at the prescribed location of the frame. Then the absolute value of the 1st accumulating value is limited at a 1st prescribed value decided by a delay stage number of a delay circuit 12, an adder circuit 17 obtains a 2nd accumulating value by accumulating the absolute value of the 1st accumulating value and when the 2nd accumulating values are 2nd prescribed values or above, it is judged that frame synchronization is pulled-in. Thus, in the case of the occurrence of a cycle slip, frame synchronization is pulled-in a shorter time than that of a conventional synchronization pulling-in method.

Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To improve the consistency of a magnetic head with a track by simplifying the assemblage of a bearing and an actuator arm, and reducing the damage on the surface and edge part of a bearing housing. SOLUTION: The disk drive is furnished with the pivot bearing and the actuator arm. The actuator arm is furnished with the stepped pivot bearing housing 38. The pivot bearing housing 38 is provided with a 1st nominal inside diameter d2 making the pivot bearing match in this housing and a relatively small 2nd nominal inside diameter d4. The pivot bearing is furnished with a body 48 and the head 50. The head is forced-fitted into the 1st nominal inside diameter and the body is force-fitted into the 2nd nominal inside diameter respectively, thereby a bearing assembly 22 is mounted inside the bearing housing. The diameter of the body of the bearing assembly is smaller than the 1st nominal inside diameter of the bearing housing, then the bearing assembly is preliminarily matched with the bearing housing. Thus, the dynamic performance of the disk drive is improved.

Title: Laser write device
Inventor: YAMAZAKI SHUICHI
IPC: H04N1/113
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To write in the same size regardless of a paper size by providing a write clock generating means for outputting a write clock while varying its frequency corresponding to the paper size so as to eliminate magnification in the main scanning direction on the average. SOLUTION: An oscillator 31 generates a clock CLK at a fixed frequency fB based on an external command, this frequency is divided into 1/R by a frequency divider 32. Next, a phase comparator 32 detects a phase difference of this frequency divided clock and a clock from a feedback frequency divider 36, and this phase difference is converted to a voltage signal by a filter 34. A VCO 35 generates a write clock WCLK at the frequency of voltage '0' and sends it to a write processing part. Besides, the frequency of the write clock WCLK is divided by the frequency divider 36 based on an external command and it is fed back to the phase comparator 33. Thus, the frequency of the write clock WCLK can be controlled by controlling the frequency dividing ratio of the frequency dividers 32 and 36 based on the external command.  As a result, the magnification in the main scanning direction can be controlled.

The color developing dyestuff is oxidized by this radical to attain a color developing state. The good recording image is directly obtd. in this way by irradiation with the laser beam; in addition, the need for the operations of the developing and fixing processing is eliminated.

Title: Rolling piston type rotary compressor
Inventor: FUJIO KATSUHARU
IPC: F04C27/00
Filed: 1982-09-18
Abstract: PURPOSE:To improve compression efficiency through reduction of leakage through the end surfaces of a piston, by a method wherein a piston ring loosely engages with an annular groove in each of the end surfaces of the piston ring to facilitate firm adhesion of the inner radial surface of a piston to the inner radial surface of the annular groove through the flow of leak refrigerant gas and differential pressure. CONSTITUTION:Piston rings 18 are respectively attached, in a loose engaging manner, to annular grooves 17 formed on the end surface of a piston 9. When high-pressure refrigerant gas under compression in a cylinder 15 is about to leak to the inner radial side of the piston 9 through gaps at both end surfaces of the piston 9, owing to the flow of leak refrigerant gas and differential pressure, and further, owing to the movement of the piston 9 in the direction of the inner wall of the cylinder 15 during its rotation, the piston ring 18 also makes similar movement. As a result, the piston rings are moved such that each of the inner radial surfaces of the piston rings 18 is brought into firm contact with each of the inner radial surfaces of the annular grooves 17 and the each of the end surfaces of the piston ring 18 is pressed against each of the sliding surfaces of side plates 2 and 3 on both sides of the piston 9. This causes reduced amount of high-pressure refrigerant gas, being in a compression stroke, leaking to the inner radial side of the piston 9, and improves compression efficiency.

IPC: H01J37/147
Filed: 1992-06-22
Abstract: PURPOSE:To emit an exact charged the heating condition depending on the deflecting condition of a charged particle beam and the heating condition of a heat compensating means. CONSTITUTION:A charged particle beam is obtained by a deflecting means 11 which consists of a defection coil, and it is radiated to a specific position of a substrate so as to expose. A change of the radiation position depending on the deformation by the heating of the deffecting means 11 is prevented by providing a heat compensating means 12. The heat compensating means 12 compensates the heating condition of the deflecting means 11 through a control means 13 depending on the change of the deflecting condition. Furthermore, a control auxiliary means 14 to control the output of the control means 13 is also provided. This control auxiliary means 14 outputs a control auxiliary signal SS to the control means 13 depending on the heating condition of the above heat compensating means 12 and the deflecting condition of the deflecting means 11. Consequently, a position variation of the charged particle beam reaching the substarte is prevented, and a high reliability of process can be carried out.
