Title: Perfluorocarboxylic acid ester and lubricant containing perfluorocarboxylic acid ester
Inventor: KONDO HIROFUMI
IPC: C10N40/00
Filed: 1986-01-23
Abstract: NEW MATERIAL:A compound expressed by formula I (X is H, F or both; n>=6; m<=2n+1; a>=8; b<=2a+1). EXAMPLE:Linolenyl pentadecafluorooctanoate. USE:A lubricant capable of giving good lubricating effect even within a low temperature region. PREPARATION:A perfluorocarboxylic acid expressed by formula II is reacted with an alcohol expressed by formula III in almost equimolar amounts to afford the aimed compound expressed by formula I. The reaction is readily carried out by refluxing in a solvent, e.g. toluene. The compound expressed by formula I may be used alone, but is also mixed with a well-known lubricant, e.g. fatty acid amide or fatty acid ester, for use. Thereby, the temperature region can be further extended.

Title: Superconductor
Inventor: KIMURA IKUO
IPC: H01B12/16
Filed: 1988-01-21
Abstract: PURPOSE:To increase cooling capability, prevent direct contact of adjacent conductors of superconductive element wires put in the form of a belt by providing the superconductive element wire having cooling grooves in its surface and insulating material at a narrower interval than the width of the element wire to cover it. CONSTITUTION:For cooling a superconductor 21, it is immersed in cooling medium, and because the superconductive element wire is twisted, cooling medium is easy to penetrate into twisted wires through a plurality of cooling grooves 8 linearly or spirally formed in the surface of stabilizer 4. A quantity of cooling medium then goes into the twisted wires through a plurality of cooling grooves 9a formed linearly or spirally in the surface of a reinforcement wire 9. Insulating material 12 used for insulation of the outer circumference is wound roughly leaving a narrower interval than its width. Cooling effect is increased by this, and if a plurality of the superconductors 21 are combined into a belt, a predetermined insulation distance is secured, thereby direct contact of adjacent conductors with each other can be prevented.

Title: Tracer head
Inventor: KOMIYA HIDETSUGU
IPC: B23Q35/34
Filed: 1984-01-24
Abstract: PURPOSE:To make it possible to manufacture easily a tracer head with the high precision of detection by causing a current to flow through the coils arranged in the magnetic field in response to the displacement of a stylus and by generating a restoring force in the tracer head in accordance with the displacement of the stylus. CONSTITUTION:When a force DELTAF is applied to a stylus 21, the stylus 21 moves and a detector 27 outputs a voltage expressed by E=K1.epsilonx where K1 is a constant of proportionality and epsilonx is a displacement in the direction of X axis. When a voltage-current converter 29 is applied with a voltage E, it supplies to a coil 31 a current i proportional to the voltage E, and the coil 31 receives a force Fx. At this time, if the direction of a current flow and direction of the magnetic field are set so that the coil 31 may receive a force in the opposite direction of that of an X component of the force DELTAF the stylus 21 receives, the coil 31 receives a force Fc proportional to the displacement epsilonx of the stylus 21 in the direction of the X axis, and the stylus axis 22 also receives the same restoring force. And a ditector 28 of the Z axis and a converter 30 also operate in the same manner. In this way, a coil 32 receives a force Fz corresponding to a displacement epsilonz, and the stylus 21 also receives the same restoring force; thus it is possible to do the profile control.

Title: Joining of materials
Inventor: GERO CHINMAA
IPC: B23K1/20
Filed: 1990-01-20
Abstract: PURPOSE: To make it possible to clean a joint surface and to maintain a clean state by applying a deposition medium of the character that the medium evaporates by causing microexplosion when heated to a temp. below the joining temp. on the surface on the side of the part to be joined and that the medium does not substantially leave a solid content. CONSTITUTION: The material comprises a first phase which removes the foreign matter on the surface of the material to be joined and a second phase which maintains the surface of this material at a clean state. Both these phases are intended to improve the wettability of the surface to be joined and the degradation in the surface tension. If the deposition medium which evaporates at the temp. lower than the joining temp. is used to the surface of the material to be joined, the drastic degradation of the surface tension accompanied by the occurrence of the mechanical microexplosion is possible. Higher alcohols, such as glycerol, are particularly useful as the medium. The glycerol is easily available and the residues after evaporation are entirely nil. This material is relatively viscous and is, therefore, preferably added with a liquid detergent or the like as a wetting agent.  This medium evaporates completely before the end of joining and the need for a post washing stage is eliminated and, therefore, the medium is convenient.

Title: Steering operating sensitivity change-over device
Inventor: TAJI HIROSHI
IPC: B62D5/07
Filed: 1989-01-21
Abstract: PURPOSE:To make steering operating sensitivity switchable to dull in compliance with a driver's wish by constructing the title device in such a way as to make a pilot change-over valve switchable from the open oil passage position to the position of an oil passage with a throttle part as well as the flow of a part of oil pressure into a circuit for a working machine increasable. CONSTITUTION:When a switch 27 is turned on, a solenoid valve 24 is changed over to an oil passage communicating position (b), and oil pressure in a steering circuit side oil passage 29 connected to a flow control valve 11 acts upon a pilot change-over valve 23 so as to be changed over to the position (a) of an oil passage with a throttle part and is fed into a steering unit 7. At the same time, oil pressure in a steering circuit side oil passage 17 rises, the differential pressure of the pilot pressure of the flow control valve 11 becomes large, and pressure oil to be fed into the steering circuit is double throttled both in the position of the oil passage with the throttle part and at the flow control valve 11. Accordingly, the flow into the steering unit 7 is decreased, the flow into a circuit 13 for a working machine through the flow control valve 11 is decreased, and thus the steering operating sensitivity is made dull.
