Title: Production of continuous strand mat
Inventor: KATO NOBUYOSHI
IPC: D04H3/004
Filed: 1988-06-30
Abstract: PURPOSE:To produce a variety of continuous strand mats in small quantities with a simple apparatus in high yield by delivering a wound glass roving along a direction perpendicular to the axis, dividing the roving into strands, piling the strands and forming in the form of mat. CONSTITUTION:5-25kg of glass roving 1 wound in the form of a cylinder is rotated on a supporting member 2, unwound and delivered from the outer layer along a direction perpendicular to the axis and transferred to a spray gun 3 having a pair of feed rollers 4, 5 in the gun. Compressed air is introduced through a compressed air-introduction line 6 into the gun and the roving is divided into strands 9 on a mold frame 8 and blasted. A binder (e.g., acrylic resin) is scattered on the strands 9 and dried. The operation to change the kind of fiber and binder can be carried out extremely easily to improve the productivity of the strand mat.

IPC: H02K41/02
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To make a bending moment smaller and to reduce the size of a double-end stud, and to correct a track-side dimensional error easily changing a position of screwing a correcting member into a bush, by fitting a nut to a threaded part of a double-end stud inside a hole of the bush by screwing. SOLUTION: A nut 19 is fitted to a threaded part 17c of a double-end stud 17 by screwing, and a ground coil body 15 is fitted to a track 11. And one surface of the collar part 17a of the double-end stud 17 screwed up to the track 11 comes in touch with an insert 10, and inside a hole 14b of a bush 14 the nut 19 is fitted to the threaded part 17c by screwing. Since it is possible to shorten the length of the double-end stud 17 as the result of this, its bending moment becomes smaller, and it is possible to reduce the size of the double-end stud 17. Besides, a track 11-side dimensional error can be corrected easily, by changing the position of screwing up of the correcting member 16.

Title: Sampling of bottom mud in water area
Inventor: SHIYOUKO YUUJI
IPC: G01N1/08
Filed: 1989-06-26
Abstract: PURPOSE:To enable cylindrical bottom mud in a water area to be easily obtained by vibrating a pipe-shaped core sampler to apply a vibration to the bottom mud, locally liquefying the bottom mud around the sampler penetrating into the bottom mud. CONSTITUTION:A pipe-shaped core sampler 1 with a spacer 4 which has a space for allowing water to freely enter and get out therethrough on the top of the spacer 4 and which is mounted with an air vibrator 5 thereon is erected on a bottom mud surface in a water area and a uniaxial vibration is applied to the core sampler 1 by the air vibrator 5. Since the vibration is transmitted to the bottom mud and locally liquefies the bottom mud around the sampler 1, this is smoothly penetrated into the bottom mud. With a penetration, water staying in the sampler 1 flows outside via the space in the upper part of the spacer 4 to remove a resistance in the penetration. When the penetration is finished and the bottom mud is taken in the sampler 1, an airtight lid is applied to the sampler 1, the penetrated sampler 1 is drawn out and an obtained sample is taken out.

Title: Tape for magnetic recording
Inventor: NANHEI YUKIHIKO
IPC: C09D7/12
Filed: 1985-07-23
Abstract: PURPOSE:To provide a tape which has an excellent electromagnetic conversion characteristic and has high runnability and excellent durability even if the thickness thereof is decreased by providing a magnetic layer consisting of fine needle-like ferromagnetic metallic powder and high-polymer binder on at least one surface of a biaxially oriented film base for which a specific polymer is used. CONSTITUTION:The tape is constituted to <=10mum thickness by using the biaxially oriented polyethylene 2, 6 naphthalene dicarboxylate film having >=28kg/mm<2> stress at 5% elongation, >=1,000kg/mm<2> Young's modulus in the longitudinal direction, >=500kg/mm<2> Young's modulus in the transverse direction and 0.006-0.012mum surface roughness as the base and providing the magnetic layer consisting of the fine needle-like ferromagnetic metallic powder having 0.1-0.3mum length and high-polymer binder on at least one surface thereof. The above-mentioned magnetic powder is preferably incorporated at >=80wt% into the magnetic layer. Such magnetic tape has excellent coercive force and good runnability and durability even if the thickness is <=10mum. The long-time recording is thus made possible as the thickness of the tape for a cassette of a Beta system and 8mm system for home VTR can be made smaller.

Filed: 1989-06-23
Abstract: PURPOSE:To obtain an ink ribbon improved in dispersibility inexpensively without receiving the limit of a hue by using the pigment and/or dye physically adsorbed on the surface of a resin particle as the colorant in a heat-meltable ink layer. CONSTITUTION:A heat-meltable ink layer is formed on the basis of a binder resin (binder) and a colorant. The colorant is formed by physically adsorbing pigment and/or a dye on a resin particle and, as the resin particle, a polyamide or styrenic resin particle is designated and used as the core substance of the colorant. As the dye and/or pigment applied to said resin particle (physically adsorbed on the resin particle), carbon black or a dye such as Lake Red C can be designated and becomes the wall material to the core substance of the colorant. The relation between the core substance (resin particle) and wall material (dye or pigment) of the colorant is set so that the particle size of the core substance is necessarily larger than that of the wall material. The colorant is prepared by mixing the resin particle and the dye and/or pigment and rubbing both of them with each other to adsorb the fine dye and/or pigment on the surface of the resin particle.

Filed: 1992-06-19
Abstract: PURPOSE: To easily manufacture to measure a distortion with effectively high precision by a method wherein fluctuations of electric-field patterns caused by interlock of an emitter are generated as an output signal. CONSTITUTION: An elongated tab coupled to an H-shaped structure 40 is fitted on a measured sample ore together with a base plate at the free end, and interlocked in a linear direction to a plate 4, accordingly to a frame 44 by a distortion of the sample ore in a fitting position. Further, a vertical force spring plate 34 fitted on the fitting section 10 urges an emitter chip 38 provided in a center toward outward in a vertical direction rather close to the structure 40, so as to come into light contact with a detection plate 8. A conductive segment 208 of the chip 38 communicating linearly generates electric-field patterns which change in a linear direction. This is detected by sensor arrays 232, 236 of the plate 8 fixed to the plate 4, and an IC 228 provides a direction wave signal showing a change of electric-field patterns to a conductive seat 240.  Thus, a distortion of the sample ore can be measured precisely.

Title: Mos-fet integrated circuit device
Inventor: KOGA AKIHIKO
IPC: H01L29/78
Filed: 1983-09-02
Abstract: PURPOSE:To improve the protective capability of overvoltage by making the threshold voltage of a parasitic MOS-FET for protection lower than that of other parasitic MOS-FETs and higher than that of an input MOS-FET. CONSTITUTION:The thickness d2 of a field oxide film 7 in a region constituting a parasitic MOS-FET Q2 for protection is made thinner than that of field oxide films in other sections. Consequently, the threshold voltage of Q2 is lower than that of other parasitic MOS-FETs. However, the threshold voltage Q2 is higher than that of Q1 because the field oxide film in Q2 is far thicker than a gate oxide film. Accordingly, an MOS-FET integrated circuit device having high overvoltage protective capability is obtained by using the MOS-FET Q2 having low threshold voltage as a protective element.
