Title: Head supporting and oscillating mechanism for magnetic disk device
Inventor: SASAMOTO ASAO
IPC: G11B21/16
Filed: 1985-12-17
Abstract: PURPOSE:To give sufficient rigidity to a head supporting and oscillating mechanism and facilitate miniaturization by providing a hole in which a flexible cable that extends from a head carriage to a circuit substrate passes through in the column of a supporting block that supports the head carriage holding a recording and reproducing head to allow free oscillation and thereby providing a passage and space for moving of the flexible cable even when a large-sized voice coil motor is installed. CONSTITUTION:A flexible cable 10 that extends from a switching circuit substrate 9 connected to a head 8 and fixed to a carriage block 4 is fixed to the carriage block 4 by a presser 13 and from there, it is bent to U-shape and reaches to a pre-amplifier substrate 14. By making the column of a supporting block 19 using two columns 19A and 19B and making a hole 20 that passes the flexible cable, passage of the flexible cable can be ensured even when a voice coil motor becomes large. Accordingly, a head supporting and oscillating mechanism having sufficiently high rigidity can be supplied. It is enough to make the longitudinal size 24 of the hole 20 slightly larger than the width 23 of the flexible cable 10.

Abstract: PURPOSE:To eliminate the problems of the fogging of an image, etc., by preliminarily stirring a developer prior to the start of the control of the concn. of toner when it is judged that tame output value of a toner concentration sensor is in prescribed or more output rising. CONSTITUTION:The latest output value of a toner sensor 5 is simultaneously detected by a completion detecting means 9 and stored by a storage means 10 whenever a copying action is completed.

Abstract: PURPOSE:To provide superior antidim properties by melt extruding polyolefin kneaded with a non-ionic surface active agent from a T-die to a base through a bonded layer and laminating a polyolefin layer prepared by a cooling roll and nip rolls. CONSTITUTION:A bonded layer 3 is formed on the side of a printed layer 2 of a base 1, and then polyolefin kneaded with a non-ionic surface active agent is melt extruded out of a T-die 10, immediately after which polyolefin layers 5 prepared by a cooling roll 11 and a nip roll 12 are fixed by pressure and laminated on the bonded layer 3 of the base 1 by means of nip rolls 13 and 14 to manufacture a film. Not only laminating the polyolefin layers 5 directly with the bonded layer, but also the structure of interposing layer 6 to be interposed between them can be formed. Said interposing layer 6 can be provided on the base 1 on which the polefin layers 5 are laminated, or provided by extruding simultaneously at the time of extrusion. Lowering of bonding because of bleeding out of the surface active agent can be prevented and also the amount of thermal decomposition of the surface active agent included in the polyolefin layers is small so that antidim effect can be demonstrated by the process.

Title: Non-linear coiled spring
Inventor: SUGANUMA OSAMU
IPC: F16F1/02
Filed: 1986-11-27
Abstract: PURPOSE:To obtain the spring character such that it rises in accordance with a curve of the second order as a stroke increases, by enclosing oil with a marginal void space and freely compounding the characteristics of three items, i.e. a metal spring, an air spring, and a rubber. CONSTITUTION:When the vehicle height becomes low, a control valve 13 functions so that the oil from a pump 12 is supplied to marginal void spaces 3 and 4, while, when the vehicle height becomes high, the oil in the marginal void spaces 3 and 4 is returned to a tank 14, thereby adjusting the vehicle height. As a result, when pipes 2, which are placed at a certain pitch, are brought in contact and are compressed with each other, the oil in the marginal void spaces flows into an oil chamber 8, pushing down a free piston in spite of gas pressure. Accordingly, a spring characteristic, in which the characteristic of a metal spring and that of an air spring are compounded, can be obtained. In addition, by increasing the thickness of the pipe 2, the characteristic of a rubber spring can also be superimposed. Thus, as the stroke increases, the spring characteristic rises gradually in accordance with a curve of the second order.

Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To obtain a soln. for wearing or storing contact lenses which does not need a special apparatus nor a troublesome operation, can easily improve the water wettability of a contact lens, and enables filtration sterilization by using an aq. soln, contg. polyvinyl alcohol having specified degree of polymn. and degree of saponification in a specified concn. SOLUTION: This soln. is an aq. soln. contg. 0.1-3.0g/100mol polyvinyl alcohol having an average degree of polymn. lower than 1,000 and a degree of saponification of 85-95mol.%. Polyvinyl alcohol having an average degree of polymn. of 1,000 or higher sometimes gives an aq. soln. which exhibits an inferior water wettability and a high viscosity and does not enable filtration sterilization. A degree of saponification of polyvinyl alcohol lower than 85mol% gives a contact lens an insufficient water wettability, while that higher than 95mol% decreases the water wettability and degrades the solubility of the polyvinyl alcohol.
