Title: Method and apparatus for securing finish precision of groove of roller as tripod element
Inventor: SUGIYAMA EIHIKO
IPC: F16D3/20
Filed: 1978-02-22
Abstract: PURPOSE: To secure finish precision simply, by forming outer surface of the legs of a tripod element, the legs which determine the grooves of its rollers, into cylindrical shape, and by correcting the outer surface deformation after hardening process.  
     CONSTITUTION: Tripod element 1 is so designed that its legs 4 may have cylindrical outer surface 4a which is perpendicular to the base plane 5. After hardening process, the base plane 5 is placed on a wall 7 installed on a plane 6, and the deformation of  each leg 4 caused by hardening is corrected by pushing a jig 8 with cylindrical outer  surface or jig 9 with cylindrical inner surface on the ends of respective legs 4. For  example, when a leg 4 bends to inside from the normal position, it is pushed back  to the normal position by means of the jig 8, on the contrary when it bends to  outside, it is pushed back to the normal position by means of the jig 9.

IPC: F16D3/74
Filed: 1983-02-10
Abstract: PURPOSE:To measure the torque of a rotary shaft, by such a simple and inexpensive constitution that displacement angle mutually generated in the flanges of a drive shaft and a driven shaft are detected by a mutual displacement angle detecting mechanism and transmission torque is detected by the product of the displacement angle and spring constant. CONSTITUTION:When power is transmitted to the side of a driven shaft 2 from a drive shaft 1, a coil spring 9 is distorted only at the angle corresponding to the torque of transmission power and a mutual angle is held between the flanges 5, 6 of both shafts. Marker sensors 11, 12 generate the pulse signals corresponding to the displacement angle with respect to this displacement. A phase angle is generated in the mutual pulse signals and, therefore, if they are treated with a signal processing device 13 and only the phase angle is displayed, the mutual displacement angle of the flanges 5, 6 can be displayed and, if said angle is multiplied by the elasticity constant of the coil spring 9, transmission torque can be displayed.

Title: Pipe joint
Inventor: UENO TAKAHIRO
IPC: F16L33/00
Filed: 1995-01-13
Abstract: PURPOSE: To improve watertightness in the vicinity of the joint part of two half cylinder members by setting the opening width of the joint part of the half cylinder member smaller than two times the depth at the center of the opening width. CONSTITUTION: The opening width S on the joint part of a half cylinder member 13 is set smaller than two times the depth D at the center of the opening width S. When a helical corrugated pipe 11 is pinched and tightened with the two half cylinder members, the helical corrugated pipe 11 is pushed in the half cylinder member, and hence the half cylinder member is elastically deformed so as to be spread on both sides. As the reaction, a hard resin molding 15 generates elastic restoring force, the packing layers 17 in the vicinity of the joint of the two half cylinder members 13 are pressed onto the outer circumferential face of the corrugated pipe 11. Hereby, watertightness in the vicinity of the joint part of the two half cylinder members is improved, and hence water leakage can be prevented.

Abstract: PURPOSE:To prevent the temperature increase of a beam duct by providing two emitted light absorbers in such a manner that the respective concave parts face to each other with a beam orbit between them, and reflecting and attenuating an emitted light by the both concave parts. CONSTITUTION:Radiated light absorbers 2, 3, are curved so that they can be provided along the deflection of a beam duct 1, and concave parts 2s, 3s having a semi-circular sectional form are formed on one surface of each absorber in such a manner that the both concave parts 2s, 3s face to each other with a beam orbit Q between them and the focus of the concave parts 2s, 3s accords with the beam orbit Q. A cooling channel 4 having a cooling liquid nitrogen passed through its inner part is provided on a determined part of the opposite surface of each concave part 2s, 3s of the emitted light absorbers 2, 3. Thus, an emitted light is absorbed and attenuated while it is reflected between the both concave parts 2s, 3s. In this case, although the temperature of the emitted light absorbers 2, 3 is increased, the heat is released to the duct outside by the cooling channel 4, and the heating of the beam duct 1 is prevented.

Title: Horn speaker
Inventor: OONO MASAHARU
IPC: H04R1/30
Filed: 1980-02-19
Abstract: PURPOSE:To enable to prevent the softening due to Joule heat and friction with magnetic gap, by filling magnetic fluid in the magnetic gap and using soft dome diaphragm plate as the diaphragm plate. CONSTITUTION:When magnetic fluid 21 is filled in a magnetic air gap 5, greater audio current flows to a voice coil 7 to produce Joule heat. It is delivered quickly to the center pole 1 and yokes 2,4 via the magnetic fluid 21 having about 4 times heat conductivity and it is discharged into air through the aluminum cast 13 and horn 16. Thus, the heat delivered from the voice coil 7 to the soft dome diaphragm plate 20 is less, and even if the power of about 40W is input to the voice coil 7, the root of the diaphragm plate 20 can not be softened by the heat. Further, since the voice coil 7 is held at the center of the magnetic air gap 5 by the force in which the magnetic fluid 21 is concentrated to the magnetic pole in the magnetic air gap 5, the gap friction due to deformation can be avoided.
