Title: Assembly method for equipment having clearance between members
Inventor: UEHARA TADAYOSHI
IPC: F04D5/00
Filed: 1988-05-19
Abstract: PURPOSE:To build both members with a predetermined space melting a protrusion to be removed by forming a protruding part of predetermined height in one member in its opposed surface and the protrusion of melting substance with its height equal to the protruding part and removing it thereafter adapting the other member to the protrusion to be fixed. CONSTITUTION:A circular annular protruding part 15 is formed in height of predetermined clearance dimension in one member in its opposed surface. And two or more short pillar-shaped protrusions 10, melted by fuel, is formed in height a little larger than height of the protruding part 15. Utilizing the protruding part 15, the protrusion 10 is processed so as to obtain its height equal to the height of the protruding part 15. Next the protruding part 15 is cut and removed, thereafter the other member adapts its opposed surface to the protrusion 10, and both the members are fixed to that position. Accordingly, a clearance between both the members obtains a predetermined size. Next melting the protrusion 10 by fuel, the members are easily assembled by enabling the clearance to be accurately obtained.

Title: Thermal recording medium
Inventor: YAMAGUCHI TAKEHITO
IPC: B41M5/28
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To improve the heat sensitivity and the concentration of a colored image and also enhance the running and sticking (head matching) properties and further, the adhesion between a support and a recording layer and their flexibility by adding polyester urethane as a binder resin. SOLUTION: Polyester urethane resin is used as a binder for the recording layer of the thermal recording medium. Polyester urethane is an elastomer having a urethane bond in the molecular chain and is obtained by causing a chemical reaction among saturated polyester obtained through a condensation reaction between a polybasic acid having normally two or more carboxyl groups and a divalent alcohol, and an organic diisocyanate and a chain extender. The polyester urethane resin is used alone or used with a binder resin in a mixed state according to necessity. Thus it is possible to improve the adhesion between a transparent support and the recording layer and at the same time, enhance their flexibility.

Filed: 1987-05-20
Abstract: PURPOSE:To measure a material to be inspected, with high accuracy, by deciding a radius of a conductive body so that an ultrasonic wave is focused to a prescribed position of the material to be inspected. CONSTITUTION:When a circular conductive body 4 of an electromagnetic ultrasonic transducer 1 is set so as to be opposed to the surface of a material to be inspected 7, a magnetic line of force 19 emitted from a permanent magnet 2 is made incident vertically onto the surface of the material 7. Accordingly, to the surface of the material 7, a bias magnetic field 9 being vertical to the surface is applied. Subsequently, when a high frequency current is allowed to flow to the conductive body 4, a circular and alternately reverse high frequency current 10 flows to adjacent branch conductive bodies 4a-4e. Next, by the current 10, a circular and reverse high frequency induced eddy current 11 whose direction becomes reverse to the current 10 flows to the surface of the material 7. Also, by an intersection of the current 11 and the magnetic field 9, Lorentz's force 12a-12e being parallel to the surface of the material 7 is generated in the material 7. This Lorentz's force 12a-12e is also circular and becomes an opposite phase alternately, in the same way as the current 11. Also, the dimension of each radius of the Lorentz's force 12a-12e becomes the same as each radius of the branch conductive bodies 4a-4e, and an ultrasonic wave which is focused to one point.
