Title: Processing method for crank shaft
Inventor: FUKUDA SHIGEZO
IPC: F16C3/06
Filed: 1985-03-25
Abstract: PURPOSE:To increase the fatigue strength of a crank shaft by providing a repeated tensile load ranging from zero to the plastic deformation zone for a prescribed time at a prescribed frequency along the journal shaft center so as to provide an uniform residual stress at the pinfillet part. CONSTITUTION:The end of flywheel fitting part 5 of a crank shaft 1 is fixed to a level block 6, and a gear side end part 7 is fixed to a ball joint coupling 8, and then the coupling 8 is connected to a tensile load machine. Accordingly, it follows that a tensile load is acted by the ball joint coupling 8 along the shaft center of journals 2. The tensile stress ranging from zero to the value sigmamax in which plastic deformation is caused at a pinfillet part 4 is applied to the fillet part 4 at a frequency of about 50Hz by a tensile load machine. And, the time in which a repeated load is added is approximately 1-3min, and at the time the repeated load is added so that the strain at the fillet part 4 which is nearest to the flywheel becomes to be 3X10<-3> or more.

Abstract: PROBLEM TO BE SOLVED: To make it possible to cope with a variety of output position detection patterns by detecting the tip end or rear end is rotating direction of a ring- shaped magnet by a detection element and then outputting ON or OFF signals. SOLUTION: A ring-shaped magnet 16 is used; the magnetizing angle (portion shown dark) of the magnet 16 is set to 120 deg., and these Hall ICs 9a and 9b are arranged to the angle positions of 0 degree and 80 degrees by using only two Hall ICs 9a, 9b as detection elements. With this construction, when a motor actuator is driven, Hall IC 9a turns ON when the output shaft is 0 degree, and the Hall IC 9b remains in OFF state. Next, when the output shaft rotates to the position of 80 degrees, the Hall IC 9a remains in off state, and the Hall IC 9b is set from OFF to ON. Moreover, if the output shaft rotates to the position of 120 deg., the Hall IC 9a is set from ON to OFF, and the Hall IC 9b remains in ON state.

Title: Fluororesin-impregnated carbonaceous material and its production
Inventor: TOJO TETSURO
IPC: C04B35/52
Filed: 1993-02-10
Abstract: PURPOSE:To obtain a material revealing high environment breaking performance for a long period of time by impregnating a carbonaceous material whose open porosity and average pore radius are limited with fluororesin heated and melted in a pressure vessel and applying pressure at which a specified impregnation ratio is obtained to it. CONSTITUTION:Fluororesin which is melted at 80-250 deg.C is heated and melted in a pressure vessel and a carbonaceous material of 5-20% open porosity and 0.1-2.5mum average pore radius is immersed in the molten fluororesin. Next, the pressure vessel is set at the pressure at which the impregnation ratio of the fluororesin is >=20% to obtain an object material. The higher the open porosity, the more quantity of impregnatable fluororesin to the whole carbonaceous material is increased. When the open porosity is less than 5%, the improvement of environment breaking performance such as water-repellency and nontackiness is not expected. On the other hand, when the open porosity exceeds 20%, the impregnatable fluororesin is increased, but nonuniformity in the impregnation is apt to be occurred to cause a part lacking in the environment breaking performance. The average pore radius is a factor of determining the easiness of the impregnation of the fluororesin.

Title: Method for treating board
Inventor: ORIGASA TOSHIYUKI
IPC: B27K5/00
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To reduce a formaldehyde amount of a board containing formaldehyde dispersible resin by first emitting an ionized radiation to the board, and thereafter leaving to stand the board for a predetermined time in a vacuum state. SOLUTION: An ionized radiation 4 is emitted from an emitting unit 3 to the board 1 while moving the board 1 in a direction of an arrow on a conveyor 2. Thus, dissipation of formaldehyde in the board 1 is expedited. The emission is conducted simultaneously or sequentially from both front and rear surfaces of the board 1. This is preferable when transmission power of the radiation 4 is weak, when the board 1 to be emitted is thick or when a decorative sheet easily changed in properties by the radiation 4 is laminated on the surface.  That is, since an intensity of the radiation 4 is attenuated according to an exponential function of an impregnating distance, when it is emitted from both the surfaces, attenuation of the intensity at a center in the board is prevented without extremely increasing the intensity near the front surface of the board, and homogeneous and satisfactory formaldehyde can be removed in the overall thickness direction in the board.

Title: Production of vertical magnetic recording medium

IPC: G11B5/667
Filed: 1985-03-26
Abstract: PURPOSE:To simplify the formation of an Fe-Ni film by reverse-sputtering a nonmagnetic Ni-P film and converting the surface of the Ni-P film into a soft magnetic material. CONSTITUTION:The surface of an aluminum substrate 1 is previously washed and nonmagnetic Ni-P is thickly electroless-plated thereon. The surface of the nonmagnetic Ni-P film 2 is mechanically planed and flattened to reduce the surface roughness. Then the substrate 1 having the film 2 is reversely sputtered by a sputtering device. Subsequently, a Co-Cr film 3 is made again by sputtering. Consequently, the formation of a soft magnetic film of another composition such as an Fe-Ni film can be dispensed with and the process is simplified.

Title: Charged particle detector
Inventor: KAWAMURA KIYOKAZU
IPC: H01J43/24
Filed: 1988-03-18
Abstract: PURPOSE:To make the assembly and the regulation works easier and to multiply the number of releasing electrons remarkably by binding and composing plural taper-form channel tubes for electron multiplying purpose in an unparallel and tapered form. CONSTITUTION:Since channel tubes 21,... are formed in a taper-form making the diameters smaller as they approach the electron injection side, the distances between passages of the secondary electrons are shortened as the secondary electrons advance inside the channel tubes 21,..., and the striking numbers of them are multiplied indicatively. Furthermore, not only the channel tubes 21,... are formed in a taper-form, but also the whole electron multiplying tube is formed in a so-called taper-form forming unparallel and making the particle incident side higher while the electron output side lower. As a result, the taper- form coefficient is increased, and the numbers of striking of the secondary electrons are increased much more. And since the size of the electron output side is small as a whole even though numerous channel tubes 21,... are bound, the assembly and the regulation works are made much easier.
