Title: Method for joining two members
Inventor: SAWAHATA KAZUO
IPC: B21D39/00
Filed: 1983-08-10
Abstract: PURPOSE:To join easily and surely a cylindrical member perpendicularly to a plane member or a cylindrical member by pressing the vicinity of a joining part at one side locally from the axial direction and deforming plastically a rugged part formed at said side. CONSTITUTION:Both of the 1st and 2nd members 1 and 2 are arranged by fitting the bottom part of member 1 to the recessed part of member 2. A die 3 descends while sliding on the outer periphery of member 1 to concentratively press the upper surface of the vicinity of the inner periphery of member 2 by its male teeth 3A. Then the member 2, made of soft material, flows plastically and perpendicularly to the spaces caused by a rugged part 1B. That is, the small projecting parts provided to the hard material gnaw into the soft material, and the soft material deformed plastically and locally by the projecting parts is joined to the hard material by a highly tightening force caused by an elastic stress generated at said part. Thus, the joining is completed by removing the die 3 thereafter.

Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To separate an immobilized magnetic particle of a target substance from a sample with a simple operation by using an inner plate for loosely inserted in a rector having an opening part in its top part and a magnet fitted in its inside. SOLUTION: A target substance is immobilized to a magnetic particle 3 by injecting the target substance and the magnetic particle 3 in a reactor 1 having an opening in its top part. An inner plate 11 having a magnet 21 fitted in its inside is loosely inserted in the reactor 1, so that the magnetic particle 3 is stuck on the outer surface of the plate 11. Secondly, when the plate 11 and the magnet 21 are taken out from the reactor 1, the magnetic particle 3 is separated from the sample liquid in such a state as to stick to the plate 1. After that, the plate 11 is loosely inserted in another reactor 4, the magnet 21 is taken out, and the stuck magnetic particle 3 is dispersed. This constitution can separate the magnetic particle 3, having the target substance without any contamination immobilized thereto with a sample operation.  The magnet 21 does not touch the sample, so that the possibility of contamination corrosion is eliminated.

Title: Magnetic head
Inventor: TAKAHASHI TAKESHI
IPC: G11B5/127
Filed: 1986-06-20
Abstract: PURPOSE:To record and reproduce a signal with high frequency and high density by using a bulk shaped ferromagnetic oxide for a back core and constituting the vicinity of a front gap by a laminater of a metallic magnetic thin film and an insulation thin film. CONSTITUTION:Since the laminator 3 constituting a magnetic gap 4 is constituted by the metallic magnetic thin film 1 having a high saturated magnetic flux density, a large recording magnetic field is caused at the recording. High frequency loss is prevented by laminating the metallic magnetic thin film 1 having a thickness designed in response to the frequency is laminated to the front core at the reproduction. Further, a low relactance magnetic path is formed by constituting the back core by the bulk shaped ferrite material. Since the tape slide face is in parallel with a face of the inter-layer insulation film 2 forming the magnetic path and orthogonal to the magnetic gap 4, the face does not like a pseudo gap. Thus, even a high frequency signal is reproduced at a high efficiency.

Title: Damper mechanism with variable amount of absorbed shock energy
Inventor: BAN ITSUKI
IPC: F16F9/44
Filed: 1982-08-24
Abstract: PURPOSE:To enable fine control of the amount of absorbed shock energy by a method wherein a slant choke groove, having a cross section in which the top dead center side is wider and the bottom dead point side is narrower, is engraved in a cylinder, and movement of a dead point causes changing of the flow of a working fluid. CONSTITUTION:When a force is exerted on the head part of a piston rod 4, a piston 3 moves downward, and an underlying working fluid 12 is pressurized and flows to the upper part side of the piston 3 through a choke groove 21. As the piston 3 moves to the lower part, the choke groove 21 gradually reduces in cross-sectional area, the velocity of flow increases, and viscosity resistance increases to dissipate the energy outward as the heat. When the external force is removed, the piston 3 is rapidly returned to its original position through the elastic force of a spring 5. When it is necessary to increase the amount of shock to be absorbed, a regulating part 23 shall be turned, and the cylinder 2 shall be shortened by screwing it in, based on a mark line indicating part 16 and graduations 17 which are notched on the outer periphery of a cylinder 2 and seen through a window part 18. This narrows the cross-sectional area of the choke groove 21 at a dead point, and permits absorption of the large amount of shock to that extent with the same stroke ST, and thus the recovery time shall not be elongated due to an increase in the elastic force of the spring 5.

Title: Driving method for ccd type image pickup element
Inventor: FURUSAWA TOSHIHIRO
IPC: H04N5/335
Filed: 1986-06-20
Abstract: PURPOSE:To obtain an image signal free from blooming by idling an accumulation part and sweeping off unnecessary electrostatic charge in the accunlulation part to the outside immediately before transferring optical charge from an image pickup part to the accumulation part. CONSTITUTION:Rapid pulses g' having the same speed and continued more than the number of rapid pulses (g) for transferring the frames of driving pulses phi2 and slow pulse h' consisting of a several pulses are continuously formed immediately before the rapid pulses (g). Consequently even if strong light is projected near the border between the image pickup part 11 and the accumulation part 12 during a period T1 and excess charge flows into the accumulation part 12, the accumulation part 12 is idled by the pulses g' for the pulses phi2 and a horizontal transfer register is also driven similarly to the output of an image signal synchronously with the idling, so that the inflow excess charge is swept off to the outside. Since the number of pulses g' is different from the number of pulses (g) and larger than the number of picture elements in the vertical direction, residual charge C' from the accumulation part 12 to the horizontal transfer part 13 can be removed by the excess pulses g' and the residual charge C' can be surely and completely removed by the following pulses h'.
