Title: Diecing method
Inventor: KOMINE SUSUMU
IPC: B23H5/08
Filed: 1977-10-17
Abstract: PURPOSE:In the diecing method of semi conductor wafer by diecing grinding stone which is the metal bond diamond grinding one, electrolyte is applied as a coolant with direct curent and surface arrangement of the grinding stone is always executed during the diecing process for maintaining the excellent cutting capacity. CONSTITUTION:A semi conductor wafer 5 is placed on a moveble table 4 and a rotating diecing grinding stone 3 is pressed to the material 5 and a coolant 7 consisting of the electrolyte is dispersed to this pressed part through a nozzle 6.

Title: Method for preserving silane-grafted polyolefin
Inventor: KATOU MASAHIRO
IPC: C08L101/00
Filed: 1983-07-07
Abstract: PURPOSE:To preserve surely and inexpensively a silane-grafted polyolefin over a long period of time, by enclosing said polyolefin together with a specified org. silane in an airtight container. CONSTITUTION:A silane-grafted polyolefin is enclosed in an airtight container together with org. silane of the formula RR'SiY (wherein R is a monovalent oletinically unsaturated hydrocarbon group or a hydrocarboxyl group; Y is a hydrolyzable org. group; R' is Y or a monovalent hydrocarbon group other than aliph. unsaturated hydrocarbon groups) in an excess amount of 0.3-1wt% based on said silane-grafted polyolefin. Pref. said org. silane is enclosed at 60-80 deg.C, because it is vaporized in an isolated form at this temperature to fill the container and expel the air nearly completely from the container and moisture in the remaining trace amount of air is reacted with the silane vapor, whereby the water concn. in the container is reduced to 0%.

Filed: 1988-05-20
Abstract: PURPOSE:To obtain an excellent bearing of high reliability by setting a spirally grooved thrust cap, which is provided to prevent scattering of grease and slipping-off of a disk, to a groove in the upper part of a fixed shaft. CONSTITUTION:A fixed shaft 11 is provided which is fixed to a lower cylinder 9 which constitutes a radial bearing through the disk (up and down spirally grooved) and oil and constitutes a thrust bearing through a thrust plate 7 (spirally grooved) and grease without contacting, and a thrust cap 29 provided with a spiral curve in the upper part is set to the groove in the upper part of the shaft 11 by light press-fitting. Consequently, scattering of grease constituting the thrust bearing is gathered to the thrust bearing part in the center by the spiral curve, and the amount of grease is reduced to prevent reduction of an extent of floating. Thus, the reliability is improved.

Title: Photographic lens
Inventor: KOBA KAZUNORI
IPC: G02B1/11
Filed: 1981-08-08
Abstract: PURPOSE:To limit only the transmission of light of a wavelength region where the quantity of transmitted light is too much sharply and to prevent reflection thoroughly with light of other wavelength regions by coating the multilayered reflection preventing films which are so constituted as to have large reflectivity in said wavelength region on at least one lens surface. CONSTITUTION:SiO2, ThF4, LaF2, Na3(AlF4), CeO2, TiO2, Ta2O5, ZnS, ThO2, MgO, CeF3, LaF3, NdF3, BeO, ThOH2, InO2 are used for the materials constituting the respective layers of reflection preventing films relating to this invention  and these materials are formed on the surface of a substrate glass B by vacuum  deposition of, for example, ZrO2 and MgF2 respectively successively until a prescribed film thickness is attained as shown in the figure, whereby multilayered  reflection preventing films C are produced. If the films are constituted in such a  way, the breaking of color balance as a result of the coloring of the glass constituting the lens system per se or an increase in transmitted light of a blue  color owing to the influence of the other reflection preventing films is corrected by reflecting only the light of a blue color with the multilayered reflection preventing films C and decreasing the rate of transmission thereof, whereby the  good color balance is obtained.

Filed: 1989-05-19
Abstract: PURPOSE:To take off a friction noise and a striking sound generated in a cylinder and to eliminate an unpleasant and anxious feeling of passengers by providing a cage-form plunger guide device formed of a superhigh polymer material of a low friction coefficient inside the cylinder. CONSTITUTION:Inside a cylinder 6, is installed a plunger guide device 17 formed in a cylindrical cage which is composed of circular rings 18 with the bore larger than the outer diameter of a bottle plate, contacting to the inner side of the upper and the lower ends of the cylinder 6, and guide rods 19 combining the upper circular ring 18 and the lower circular ring 18 in the vertical direction, both of which are made of a material of a low friction coefficient such as a superhigh polymer polyethylene or Teflon, for example. When the bottom plate 14 of the plunger 3 is contacted and struck to the inner wall of the hydraulic cylinder 6, the bottom plate 14 is not hit directly to the inner wall of the cylinder 6 but contacted to the plunger guide device 17. In this case, since the plunger guide device 17 is made of a soft material of a low friction coefficient, and the contact surface is smooth, an abnormal condition such as a friction noise and a striking sound between a plunger 3 and the cylinder 6 is scarcely generated.

Filed: 1992-05-18
Abstract: PURPOSE:To obtain a cleaning web for copy machine which has sufficient heat resistance and also is a uniform thin sheet body, by specifying a raw material for cleaning web. CONSTITUTION:The web consists of mixed made paper which is made of polyphenylene sulfide short fiber and aromatic polyamide short fiber by a wet paper making method and is produced at a constant thickness by a calendering work. It has such merits that the smaller the single yarn sizes of both fibers are, namely the thinner denier they are, the more uniform is the mixed made paper and the much easier is the formation of a thin sheet and the softer is the mixed made paper. The polyphenylene sulfide short fiber is <=3 deniers in the single yarn size, preferably <=2 deniers and the aromatic short fiber is <=2 deniers in the single yarn size, preferably is the short fiber being <=1.5 deniers and/or pulp. Especially when the aromatic polyamide short fiber with thinner denier is used, wear of a coating layer on a fixing roller surface is less.

IPC: G04D7/00
Filed: 1978-10-11
Abstract: PURPOSE: To secure measurement for the rough torque by supplying the pulse of the minimum duration which can always turn to the step motor of the analog watch.  
     CONSTITUTION: Motor driving circuit 301 prepares the pulses of several different types of duration plus the correction pulse featuring sufficiently ample duration to supply them to motor 302. Rotation detector circuit 303 detects the rotation and non-rotation of motor 302 by the difference of the induction voltage caused by the vibration of the rotor. At the same time, control circuit 300 gives control so that the pulse of the minimum duration which is always rotatable may be supplied to motor 302. At the same time, various types of data are obtained, and the measurement results of a fixed time such as 24 hours, that is, the duration of the driving pulse changing momentarily plus the driving frequency and correction frequency with each pulse duration are counted and memorized to be displayed at display unit 306 after the analog conversion. In this way, the rough torque can be measured, and at the same time the defect of the train wheels can be detected by the cyclic condition of the fluctuation of the rough torque.
