Title: Magnetic head unit
Inventor: KUMAKURA KUNIO
IPC: G11B5/127
Filed: 1989-07-11
Abstract: PURPOSE:To maintain the magnetic characteristics of the magnetic head always well by forming a tape guide of a thermoplastic resin compounded with potassium titanate having a whisker structure. CONSTITUTION:The tape guide is formed by using the thermoplastic resin compounded with the potassium titanate having the whisker structure. The compounding ratio of the potassium titanate having the whisker structure is preferably set at >=5wt.% and <=40wt.% of the weight of the thermoplastic resin. The effect of preventing the dislodgment of the magnetic powder from the magnetic tape is not obtd. if the compounding ratio of the potassium titanate is below 5wt.%. The surface of the tape guide roughens and there is the problem that the dislodgment of the magnetic powder of the magnetic tape arises if the compounding ratio of the potassium titanate exceeds 40wt.%. The adhesion of the magnetic powder of the magnetic tape to the tape-sliding surface of the magnetic head is prevented in this way and the magnetic characteristics of the magnetic head are maintained always well.

Title: Supercontact zoom lens system
Inventor: MASUMOTO HISAYUKI
IPC: G02B15/173
Filed: 1984-08-28
Abstract: PURPOSE:To reduce the number of pieces for constituting a titled lens system although it is compact, and also to obtain a high performance by constituting said lens system with four lens groups having positive and negative refractive powers, so that the first and the fourth lens groups are moved to an object side from an image side for the purpose of zooming. CONSTITUTION:A titled lens system consists of lens groups I -IV whose refractive powers are positive, negative, positive and negative in order from an object side. Also, for the purpose of zooming to the longest focal distance state L from the shortest focal distance state S, the lens groups I, IV are moved to the object side from an image side so that an interval to the lens groups II, III is increased or decreased, respectively, and also a prescribed condition is satisfied. Accordingly, in the state S, this lens system becomes a telephoto type consisting of the lens group of positive and negative refractive powers, therefore, its overall length is very short and it becomes compact. Also, at the time of zooming from the state S to L, the lens group IV is moved by increasing its magnification, therefore, the zooming action is shared with the lens groups II, III and IV, the moving extent of zooming is reduced even if the power of each lens group is weakened, and the number of pieces for the constitution can also be decreased.

Title: Manufacture of piston for direct injection-type diesel engine
Inventor: KANAI AKIJI
IPC: F02B3/06
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To ensure the binding strength of a piston base material and a wear resisting ring and to improve a yield of the raw material by holding the wear resisting ring by a molding while separated from an inner wall surface of a die when the piston is casted with high pressure by setting the fiber molding for reinforcing a lip part and the wear resisting ring of the backing of a top ring groove in a die. SOLUTION: An annular recessed part 4a is formed on an upper outer peripheral side of a fiber molding 4a, an inner peripheral lower part of a wear resisting ring 5 is fitted to the recessed part 4a, and the wear resisting ring 5 is set in a die while separated from an inner wall surface 21 of an outer die 2. As the molten bath flows to a lower part of the outer die 2 through a clearance between the inner wall surface and the wear resisting ring 5 in high pressure casting, the thermal shrinkage of the wearing ring 5 by the outer die 2 can be prevented and the sufficient binding strength of a piston base material and the wear resisting ring 5 can be obtained.  As the fiber molding 4 can be also used as a holding member of the wear resisting ring 5, an inner diameter of the outer die 2 can be reduced, and a cutting margin M for cutting the casting into the desired piston shape, can be reduced. Accordingly a yield of the raw material can be improved, and the cutting work can be simplified, which shortens a working time.

Namely, the image forming position on the photosensitive body can be optionally selected by selecting the moving distance in the direction rectangular to the optical path of the lens. The moving distance in the direction rectangular to the optical axis of the lens is set up by calculating a shear between an information position and a copy specifying position by a control device and controlling a lens moving device on the basis of the calculated signal.
