Title: Infrared ray transmission body
Inventor: ISEDA TORU
IPC: G02B1/11
Filed: 1984-11-08
Abstract: PURPOSE:To form extremely easily an antireflecting layer and to improve productivity by constituting the antireflecting film provided to the end face of an IR transmission body of an amorphous high polymer. CONSTITUTION:The end face of the transmission body is cut with a cutter and while an ultrasonic oscillation is impressed thereto, a glass surface is pressed to the end face to form a specular surface. A separately prepd. org. soln. of the amorphous high polymer is coated on such surface to form a high polymer layer to a prescribed thickness. The layer is then dried to form the antireflecting layer. The amorphous high polymer has excellent smoothness of the surface, decreases scattering loss and has an excellent antireflecting effect. The amorphous high polymer is exemplified by an acrylonitrile-styrene copolymer, polyvinyl pyrolidone, ethylene/propylene/hexadiene polymer and thermoplastic urethane.

Abstract: PURPOSE:To enable a window surface having a large curvature to be uniformly wiped with an optimum urging force according to the travelling condition by providing a spacer means for operating an operating mechanism for uniforming the urging form and a control means for controlling a drive means on the basis of the exterior control signal. CONSTITUTION:When a front glass 3 is wiped by a wiper blade 12, the front end of a driven input lever 16 slides along the middle step of a cam surface 17 and an urging spring 14 is expanded and contracted delicately in response to the wiping motion of a wiper arm 6.

On the other hand, a control device 20 receives the vehicle speed signal from a vehicle speed sensor 44 to drive a drive motor 42. In the low speed travelling, a spacer member 18 is driven downward to weaken the urging force of the spring 14, and in the high speed travelling the spacer member 18 is driven upward to strengthen the urging force of the spring 14 so that the blade 12 can be pressed against the glass 3 with the optimum urging force.

In addition, a compression member 25 such as a hydraulic cylinder is assembled into a part which comes into contact with an area 9 where a verification and identification image is formed on the top force 22. Both forces 21, 22 are connected to a suction means and the writing sheet 1 and the image receiving sheet 6 are fixed by vacuum suction. Further, these forces 21, 22 are butted to each other to form a cavity 24 and after injecting a substrate resin from a gate 23, the cavity 24 is compressed to a position equivalent to the thickness of the IC card as shown by a single dot chain line using the top force 22.  When the cavity 24 needs to be recompressed, its timing depends upon how rapidly the resin is set. However, it is recommended that the compression process be performed using a compression member 25 generally 0.2-3 seconds after the initial compression.
