Title: Orientation device of magnetic field for hard disk
Inventor: ISHIKURA YASUHISA
IPC: G11B5/845
Filed: 1984-12-19
Abstract: PURPOSE:To attain the orientation properties equivalent to that of a magnetic field orientation device aiming at a high degree of orientation with a more complicated structure, by securing such a structure that can move independently a magnetic field generator having a gap for production of a leakage magnetic flux, away from an orientation working position. CONSTITUTION:When an orientation magnet 3 is set close to an orientation working position (close to a substrate), an intensive magnetic field vertical to the substrate surface is produced between the N pole of an orientation magnet 2 and the S pole of the magnet 3. This intensive magnetic field sets the needle-shaped magnetic powder 12 contained in a film 11 on the substrate 1 in the direction vertical to the substrate surface. When the magnet 3 is set apart from the substrate 1, just a weak magnetic field is produced between the N pole of the magnet 2 and the S pole of the magnet 3 since the distance is large between both counter poles. While an intensive magnetic field is produced between gaps of the magnet 2. Thus a magnetic field which is horizontal to the substrate surface and parallel to the revolving direction is produced on the substrate 1. The magnetic field powder 12 in the film on the substrate is orientated in parallel to the substrate surface.

Abstract: PURPOSE: To industrially and advantageously obtain the subject compound useful as an intermediate for medicines, agrochemicals, etc., by using a readily handleable and inexpensive reagent according to a specific method for passing dihydrofuran as a starting raw material through a new intermediate. CONSTITUTION: 2,3-Dihydrofuran is initially reacted with an orthoformic acid ester in the presence of a Lewis acid (e.g. zinc chloride) preferably at 30-40 deg.C to provide an acetal derivative of formula I (R is an alkyl), which is then reacted with a halogenating agent (preferably thionyl chloride), preferably in the presence of a base in an amount of 2-5mol% based on the acetal derivative. The resultant product is then hydrolyzed under conditions of pH4-5 and 25-70 deg.C temperature to afford a halogenated dialdehyde derivative of formula II. The obtained derivative is subsequently cyclized in the presence of a base to afford a new 1,1-cyclopropanedicarboxaldehyde of formula III. The compound is further reduced by a method for hydrolysis in the presence of a catalyst, e.g. Raney nickel to afford the objective compound of formula IV.

Title: Joining method of polymeric materials drawing-processed
Inventor: TANAKA ISAO
IPC: B29C65/08
Filed: 1988-10-27
Abstract: PURPOSE:To obtain sufficient joining strength by applying parallel vibration on the joining surface while pressing the joining surface of two joining materials, and joining them by making the joining interfaces to be formed with a thin metal layer. CONSTITUTION:An oscillator 4 is vibrated by a high frequency (supersonic wave) generator 7, and the oscillatory waves are transmitted to a horn 3, and become lateral oscillatory waves having an appropriate oscillation. A series of these systems connect to a cylinder 6, and moved to the side of a sample table 1 by pressurization from the upside by the cylinder, thus the horn 3 is press-contacted with sufficient pressure to the sample 2 of joining members set preliminarily on the sample table 1. At this condition, as the horn 3 is vibrated for a certain period parallel to the joining surfaces, frictional heat generates at the joining interfaces, and a melt layer is formed therearound. After the vibration finishment of the horn 3, they are held by sufficient pressing force until the melt layer is cured. By this manner, heat generation in the overall joining part of polymeric material joining members given drawing work is restrained, and since the return of the molecule orientation is limited to only thin melt layer generated in the joining interfaces, the strength decrease of the joining members is restrained to a minimum, and sufficient joining strength can be obtained.

Title: Controller for powder feeder, and powder feeder
Inventor: TATEISHI MAMORU
IPC: H02N2/00
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To control a powder conveyance amount in a short time with high precision and to improve the operability by utilizing a calibration curve obtained by feeder calibration at the start of supply. SOLUTION: As a duty ratio at the start of supply, a duty ratio to a target supply actual flow rate qT is found from the calibration curve obtained by feeder calibration. Consequently, only a rise response time T1 (<1sec) is needed until the set target supply actual flow rate qT is reached. Therefore, powder supply in a short time (several sec) can be performed with high precision. Further, a momentary supply actual flow rate is calculated in a feedback control area T based on the output from a load cell and the duty ratio to it is found from the calibration curve. Consequently, an error in the momentary supply actual flow rate is within <=2% and powder can be supplied with high precision.

Title: Manufacture of crosslinked polyolefin foam
Inventor: SABURI TAKESHI
IPC: B29K23/00
Filed: 1986-11-14
Abstract: PURPOSE:To mold a final foamed-molding with uniform and fine bubbles by obtaining a primary foam after a composition has been preformed. CONSTITUTION:A mold for preforming which is similar to the mold used in the primary foaming process and has 85-95% of the inner volume of a primary foaming mold is preliminarily filled with the composition in which foaming agent, crosslinking agent and further if necessary, auxiliary foaming agent and other compounding additive, are mixed with polyolefin resin, and then said composition is preformed at the temperature where foaming agent and crosslinking agent are not decomposed. When the volume of the mold used for this preforming, is equal to 85% of the volume of the primary foaming mold or less, the bubbles generated at end position are coarse, and when it is equal to 95% or more buffs are generated and a stable primary foam is not obtained. This stage must be carried out at the temperature where the foaming agent and the crosslinking agent are not decomposed. Said temperature range is changed according to the kind of the foaming agent and the crosslinking agent, but its range is generally 100-120 deg.C. The preform thus obtained is molded into a foamed molding by normal method in two stage process.

Title: Underwater drawing type parachute of underwater cruiser
Inventor: KIZAWA KOJI
IPC: F42B19/04
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to control the dropping attitude of an underwater cruiser in the air and to abruptly decelerate the cruiser without affecting trouble after landing on the sea by providing a parachute for holding a predetermined resistance area in the air, and resistance area contracting means for reducing the resistance area at the time of jumping into the water. SOLUTION: When an underwater cruiser 4 with a parachute is thrown in the air, its parachute 1 is developed, and the parachute 1 and the cruiser 4 are dropped in the coupled state. Then, when the parachute 1 is jumped into the water, the outer peripheral slinger 2 is cut by the resistance of water having much higher specific gravity and viscosity than those of the air. As a result, the vicinity of the outer periphery of the parachute 1 is wound upward to lose its function as the resistor, and only the range of the circular shape disposed with the slinger 3 is operated as the resistor. Accordingly, the cruiser 4 is drawn at the parachute 1 into the water without detrimental impact for the strength and the function, and rapidly decelerated. Thus, the cruiser can be dropped from high altitude to the shallow sea without restriction in the operating condition.
