Title: Retroreflective band
Inventor: KAWAI TAKASHI
IPC: G09F13/16
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To obtain a reflection band which may be fixed to a prescribed point without using a spring-like elastic body no matter whether this body is made of metal or plastic. SOLUTION: This retroreflective band is formed by utilizing the shrinkage force of the rubber-like elastic body in place of the restitutive force of the spring-like elastic body. The flat retroreflective band is produced by adhering the retroreflective sheet 1 to the elongated rubber-like elastic body 2, working both to the retroreflection tool of a bag body and inserting a flat plastic plate thereto. While the retroreflective band is normally held in a flat horizontal state by the plastic flat plate included in the reflection tool of the bag body, the retroreflective band is instantaneously curved and rounded by the shrinkage force of the rubber-like elastic body 2 and may be fixed to the prescribed point at the time of use.

Title: Image forming method and transfer material
Inventor: SATO MORIMASA
IPC: G03F7/004
Filed: 1990-12-01
Abstract: PURPOSE:To enable transfer to a final substrate without defects due to bubbles, etc., and to also enable satisfactory exfoliation from a tentative substrate and exposure in the air by forming a separation layer which adheres more tightly to a photosensitive resin layer than to the tentative substrate, has low oxygen permeability and softens at a specified temp. CONSTITUTION:A separation layer is formed on a tentative substrate by applying and drying a soln. of the material of the layer and a photosensitive resin layer is formed on the separation layer by applying and drying a soln. of the resin in a solvent which does not dissolve the separation layer to produce a transfer material used. The photosensitive resin layer is stuck to a final substrate under heating while applying pressure as required, the tentative substrate is stripped off and exposure through a prescribed mask and development are carried out. An org. polymer having about <=80 deg.C softening point is used as the material of the separation layer because the transfer material can be transferred to a rugged substrate optionally under pressure without leaving bubbles when the polymer having a low softening point is used.

Title: Stator block coupler for linear motor
Inventor: HORI HIRONOBU
IPC: H02K41/02
Filed: 1990-12-14
Abstract: PURPOSE:To couple a stator block firmly with no shift by providing a spring for urging a coupler to a stop part side on the other side of a stator casing and a screw hole to be screwed with a fixing screw for regulating the movement of the stator casing in the longitudinal direction. CONSTITUTION:One end of a coupling board 13a is stopped at one protrusion 7b of a fixed part 7a at the abutting part of a stator casing to be coupled and the base side of the coupling board 13a is pressed against the top board of the stator casing 7. Consequently, a coupling body 13b retracts while resisting against the force of a spring 13c and when it is inserted upto a constricted part of the fixed part 7a, it is projected by the force of the spring 13c and thereby a pawl 13g of the coupling body 13b stops at the other protrusion 7b of the stator casing 7 thus clamping the stator part 7a from the opposite sides. Fixing screws are then screwed into screw holes 20, 21 and pressed against the outer surface of the stator casing 7 thus coupling the stator blocks A each other. When the stator blocks A are coupled through the coupler 13, the stator casing 7 can be secured firmly in the widthwise direction of the stator casing 7 because the coupling board 13a is wide and the coupling board 13b comes into resilient contact with each stator casing 7.
