Patent JP-H0991816-A (JP)
Title: Disk unit
Inventor: NAKAMOTO TATSUO
IPC: G11B17/02
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of distortion and deformation of a disk and to surely perform fixation to a spindle by devising and adopting a special structure to a clamp for fixing the disk. SOLUTION: By screw-fastening the screw insertion hole 51 of the clamp 50 and the screw hole 53 of the spindle 16, pressurization force is uniformly transmitted through a J ring 55 to the disk 18A and it is fixed to the spindle 16. At the time, an area thinner than an inner peripheral part is formed on the outer peripheral side of the screw insertion hole 51 of the clamp 50 and a level difference is provided. Thus, at the time of screw-fastening the clamp 50 to the spindle 16, a part of the lower surface of the head of a screw 62 pressurizes the inner peripheral thick part of the clamp 50, an empty area is formed at a thin part and a non-contact state is attained.  Thus, at a clamp part near a screw center, the distortion generated by fastening is dispersed at the outer peripheral part of the clamp, the pressurization force applied from the clamp to the J ring 55 is uniformized, the distortion and the deformation generated on the disk are reduced and the fixation is performed.

Abstract: PURPOSE:To enhance the purity of a distillate by separating a tower top gas into a low-boiling-point gas and a high-boiling-point gas by a separation membrane. CONSTITUTION:A raw liq. is supplied to a distillation tower 1 and evaporated by a heater 2, and a part of the vapor is liquefied by gas-liquid contact while the vapor is passed through a riser.

IPC: G11B5/187
Filed: 1983-12-28
Abstract: PURPOSE:To obtain a magnetic head for floppy disc drive, which has a simple constitution and reduces damage of the surface of a medium during driving, and a driving method using this head by arranging magnetic heads provided on both faces so that they face each other on the same cylinder. CONSTITUTION:A conventional slider is eliminated to constitute a magnetic head 21 essentially with a magnetic pole 22 formed with an E core 22a and an R/W core 22b and a gimbals, and reinforcing materials 23 are attached for the purpose of enhancing the mechanical strength if required. Reinforcing materials 23 consist of, for example, bar-shaped ceramic materials reinforcing junction parts between the gimbals 24 and the magnetic pole 22, and it is unnecessary to bring them closely into contact with the whole of the magnetic pole conventionally. Therefore, it is unnecessary to polish side faces of the E core into specular surfaces, and the working process of the magnetic head is simplified, and only the core is brought into contact with the medium. On the other hand, peripheral parts of the face, which is brought into contact with the surface of the medium, of the magnetic pole 22 are chamfered as shown by 26 and 27 in the figure. Thus, pointed parts are eliminated in the part of the magnetic head brought into contact with the surface of the medium, and the medium is not damaged.

Title: Electrostatic precipitor and electrostatic precipitation method
Inventor: ITO YASUO
IPC: B03C3/00
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To lower a space-charge electric field on a surrounding wall face, etc., and to prevent the contamination of a tunnel wall face by providing a charge neutralizer forming a plasma discharge column, in which negative ions and positive ions are present at the same time, in succession to the dust collecting part of an electrostatic precipitator. SOLUTION: The suspended particles introduced from the inflow side A of an electrostatic precipitator 50 are charged in a charging part 1, about 80% of the particles are collected by the collecting part 2, and the remaining 20% of the particles are discharged from the outflow side B of the dust collecting part 2. In this case, the remaining 20% of the particles are inputted to a charge neutralizer 100 consisting of a silent-discharge charging part and forming the positive and negative charges between the parallel electrode plates. The charges are neutralized by the plasma-discharge column by the silent discharge, and a space-charge electric field formed by itself is reduced to zero. Consequently, the driving force toward a wall is weakened, and the deposition of dust on the tunnel wall face, duct and further the main tunnel wall is reduced.
