Patent JP-S54108602-A (JP)
Title: Optical reproducer
Inventor: YAMAGUCHI TAKASHI
IPC: G11B7/09
Filed: 1978-02-14
Abstract: PURPOSE:To obtain a simple and accurate controlling system suited for self-coupling system by disposing each pair of semiconductor lasers for focusing and tracking around an information read-out semiconductor laser. CONSTITUTION:Semiconductor lasers 21, 24, 25 are disposed to a substrate 26 provided with serrations so as to position forward and backward by the same distance in the optical axis direction and are so placed that the laser 21 comes on the optical axis. The divergent rays emitted from these lasers so advance that the optical axes of the three become parallel and are made approximately parallel with a collimation lens 12. After they emit from said lens, they intersect at the place of the focal length f1 of the lens 12. If an objective lens 13 of a focal length f2 is so placed that the focus comes in this position, the light beams having passed therethrough become parallel in optical axis and are focused. Hence, the light beam enter the surface of an information disc 14 perpendicularly, then it reflects perpendicularly and enters the laser 21, 24, 25 from the original paths, thus causing self-coupling. Thereby, the simple and accurate controlling system suited for the self-coupling system may be obtained.

Title: Fuel control device for engine
Inventor: KAJIWARA YOSHIHIRO
IPC: F02D43/00
Filed: 1985-01-28
Abstract: PURPOSE:To prevent after-burn and suppress torque shock, by continuing to supply a primary air to a downstream of a throttle valve for a predetermined period in a region where fuel cut is released at an engine rotational speed less than a predetermined value at deceleration. CONSTITUTION:In an engine 1 designed such that a secondary air is supplied to an exhaust passage 6, when an engine rotational speed is reduced to n2 at deceleration, a low-speed fuel control valve 14 is opened again in receipt of a control signal from a control unit 21 to thereby start fuel supply through a low-speed fuel passage 12. When the engine rotational speed is further reduced from n2 to n1, a primary air control valve 15 is closed in receipt of a control signal from the control unit 21 to thereby stop supply of a primary air. Thus, the primary air is continuously supplied until the engine rotational speed is reduced to n1 to thereby prevent after-burn. Accordingly, the engine rotational speed n2 may be set at a high value, and thereby torque shock may be suppressed.

Abstract: PURPOSE:To make a return program, by detecting the beginning position, middle position and end position of setting-aside of a tool and storing these positions in a memory and by performing rectilinear interpolation on the stored positions in the opposite direction to the setting-aside at the time of the return of the tool. CONSTITUTION:When the chipping of a cutting edge 6a at a point P1 is detected, the working person applies a machining stoppage instruction to a main control section 9 to stop the execution of a machining program PRO and moves a tool 6 to a point P2 in a manual mode so that the tool does not interfere with a workpiece 2. The working person thereafter moves the tool 6 to points P3, P4, P5 in that order so that these positions are linked with each other by imaginary straight lines. When the cutting edge 6a is stopped in each of the positions P2- P5, a switch 21 is pressed down to store the position. To return the tool 6, rectilinear interpolation is effected on the positions P5-P1 to make a return program and put it in the machining program to return the tool to the position of starting of setting-aside.

CONSTITUTION:The recording body 1 is driven forward in the direction indicated with an arrow (a) by the driving source, and also it is driven in reverse in the direction indicated with an inverted arrow (a) intermittently. On the other hand, when the recording body 1 is driven in reverse, the doctor blade 2 becomes easy to be deformed in the direction separating from the recording body 1a, therefore a lubricant 4 is engulfed between the tip part 2b of the doctor blade and the surface 1a of the recording body, and a lubricating oil film is formed. In this regard, the lubricant 4 is not impregnated into the powdery toner but is applied to the tip part 2b of the doctor blade , therefore the deterioration of powdery toner is not quickened by a lubricant, and a bad influence is not given on other process such as development, etc.

Filed: 1989-01-25
Abstract: PURPOSE:To lower increase rate of transmission torque in the low differential rotation zone as well as to raise the increase rate of the transmission torque in the high differential rotation zone by providing a spring which applies force in the direction that the first working piston is removed from the second working piston. CONSTITUTION:When relative rotation is generated between both propeller shafts 25 and 26, pressure corresponding to the number of differential rotations is generated in fluid chambers of both pressurizing force generating means 10a and 10b to pressurize both working pistons 13 and 16 in the axial direction. The piston 16 directly pressurizes a frictional clutch 10c and frictionally engages each of clutch plates 19a constituting it with clutch disks 19b through oil for clutch. On the other hand, as the piston 13 is pressurized against a compression spring 19d, it does not aid pressurizing force of the piston 16 till it overcomes the applied force of this spring 19d, but when it overcomes the applied force, it aids pressurizing force of the piston 16 corresponding to the number of differential rotations and further increases frictional engaging force between the plates 19a and the disks 19b.

IPC: H01F7/02
Filed: 1987-01-28
Abstract: PURPOSE:To obtain an excellent characteristics radial orientation magnet by providing the axis of easy magnetization perpendicular to a projecting curved surface near the curved surface and the axis of easy magnetization which is more isotropic than at the above-mentioned near position or in parallel with the curved surface at the position farther from the curved surface. CONSTITUTION:A hollow cylindrical radial orientation magnet 1 is so orientated to have the axis of easy magnetization perpendicular to the outer circumferential surface at the side of the outer circumference and the axis of easy magnetization in parallel with the outer circumferential surface at the side of the inner circumferential surface as shown by a dotted line in the interior. For this reason, if many poles are magnetized alternately N, S, N... on the outer circumferential surface, an inner magnetic path is made longer and the leakage of magnetic flux is reduced. Accordingly, the density of magnetic flux at the side of the outer circumference is increased. A desirable radial orientation magnet is manufactured from an R-Fe-B system alloy (especially, an R2Fe14B tetragon is desirable.).
