Title: Reservoir tank cap
Inventor: KOJIMA TAKAHIRO
IPC: B65D41/06
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To reduce a number of parts to reduce a manufacturing cost and also to prevent oil from leaking by forming a cap of resin and fixing the cap to an injection port by elasticity of a locking claw of resin. SOLUTION: A cap upper 20 and a cap lower 21 are made of resin. The cap lower 21 has locking claws 27, 27' formed to be folded in a U-shape. When a cap is to be fitted onto an injection port 32 of a reservoir tank 31, the locking claws 27, 27' are passed through a notch 32b of a flange 32a provided on the injection port 32, the cap is rotated to have the locking claws 27, 27' locked to the flange 32a, and the cap is fixed to the injection port 32 by elastic force of the locking claws 27, 27'. In addition, an O-ring comes into tight contact with an inner diameter of the injection port 32 to keep airtightness, and air in the reservoir tank 31 is released outside through a filter 22 made of a porous material which does not let oil through. Thus the cap can be formed of resin, a number of components can be reduced to reduce a cost, and oil can be prevented from leaking from an air vent.

Title: Sterol derivative
Inventor: TAKEHARA SADAO
IPC: C09K19/54
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To provide a new optically active liquid crystalline compound which can be added to a nematic liquid crystal in a small amount to induce a sufficient short spiral pitch, is chemically stable, does not contain a polar group such as a cyano group or an ester group, and exhibits sufficient voltage retention, even when subjected to an active matrix-driving operation. SOLUTION: A sterol derivative of the formula: St-0CF3 (St is sterol skeleton). A liquid crystal composition contains the sterol derivative of the formula. A liquid crystal element contains the composition as a component. The compound of the formula can industrially easily be produced, is chemically stable against heat, light, water and so on, and has excellent compatibility with the present general purpose nematic liquid crystals. The compound of the formula further has a characteristic that a sufficiently short spiral pitch can be induced without narrowing a temperature range, even when a small amount of the compound of the formula is added. When the compound of the formula is used for a composition for active matrices, high voltage retention can easily be obtained.  Since the compound of the formula is the same low polar compound as a host liquid crystal material, the ratio of the composition is not changed, even when the composition is subjected to a purification process using a silica gel column. The pitch is thereby not changed and does not require the readjustment of the pitch. Thus, the compound of the formula is especially useful as a chiral dopant for nematic liquid crystals, particularly as a component of liquid crystal materials for driving active matrices.

Title: Adhesion preventing mechanism for magnetic disk device
Inventor: YONEKAWA SUNAO
IPC: G11B5/012
Filed: 1987-12-23
Abstract: PURPOSE:To prevent adhesion between a head and a disk from being increased by providing a taper surface in the outer circumferential edge of the disk and bringing the surface of the disk into contact with a head slider edge with moving a rail in the outer circumferential side to the taper part when the revolution of the disk is stopped. CONSTITUTION:A taper surface 2 is provided in the outer circumferential edge of the disk. Then, when the disk is stopped and the outer slider of a head 3 is moved to the taper surface 2, the slider surface 2 goes to have an angle to a disk flat surface 1 and the taper surface 2 since the relative height of a slider edge 5, which contacts the disk flat surface 1 and the taper surface 2, is changed. Accordingly, the head 3 and the disk does not have surface-contact and a contact area can be reduced. Thus, even in a condition that the disk is stopped for a long time, the adhesion can be prevented from being increased.
