IPC: F16H21/20
Filed: 1979-02-26
Abstract: PURPOSE: To provide a steplessly variable stroke of reciprocation by a method wherein the length of parallel chain portions facing each other with a large gap therebetween is adjusted by a gap reduction mechanism.  
     CONSTITUTION: As a planetary 17 revolves, a reciprocating member undergoes reciporcation; the stroke of the reciprocation is determined by the length of parallel portions 9, 10 of an endless chain 4 which are spanned between a chain wheel 2 and a gap reduction mechanism 8 and face each other with a large gap W therebetween. By operating a stroke varying mechanism 15 to move the mechanism 8 to a position indicated by imaginary lines (two-dotted lines) c, the length of the parallel portions 9, 10 is reduced to l. Thus, the stroke of the reciporcating member can be varied steplessly in the range between L 1  and l 1 .

Title: Optical system for laser beam working
Inventor: MATSUSHITA NAOHISA
IPC: B23K26/06
Filed: 1986-02-04
Abstract: PURPOSE:To irradiate a laser beam with high energy density to a working part to attain sharp hole working reducing a melted amount around a worked hole by constituting an optical system of two cone lenses having the same inclination angle, a convex lens and a concave lens having the same focal position as that of the convex lens. CONSTITUTION:A laser beam transmitted through a cone lens 6 is expanded so that the center part is turned to the outer periphery part and the outer periphery part is turned to the inner part. When the expanded light is passed through a cone lens 7 having the same inclination angle as that of the lens 6, the light is turned to parallel light in parallel with the original laser light axis. When the light is transmitted through the convex lens 8 and the concave lens 9, the light is turned to a parallel laser beam 5' thinner than the laser beam transmitted through the cone lens 7 and formed on the same axis as the optical axis of the original laser beam because the focuses of both the lenses 8, 9 coincide with each other. Consequently, a laser beam with Gaussian distribution can be converted into a thin parallel beam with energy distribution having the highest energy at the outer periphery part and the lowest energy distribution at the center part and the drilling of metal mesh can be attained by using the parallel light such that a hole with the same diameter can be sharply worked on the same axis.

Title: Tape loading device of vtr
Inventor: SATOU KOUJI
IPC: G11B15/665
Filed: 1984-02-09
Abstract: PURPOSE:To make inclined posts unnecessary and reduce a force in the vertical direction which is applie to a tape in case of tape loading, by using an erasing head as an inclined guide member which inclines the tape to wind it around a rotary cylinder. CONSTITUTION:With the exception that an inclined pole is not provided on a moving base 17, this device has the same constitution as a conventional devices. When guide rolls 15 are moved to the right and the left of a cylinder 1 by the moving base 17 to wind a tape 21 around the cylinder 11 in case of loading, a force in the vertical direction is hardly applied to the tape 21. Though the force in the vertical direction is slightly applied to the tape 21 if guide rolls 15 are projected over an erasing head 30 and an inclined post 31 and the tape 21 starts contacting with the erasing head 30 and the inclined post 31 as the result, the position in the vertical direction of the tape 21 is not disturbed or is little disturbed because this force acts so that the tape 21 is inclined and is wound obliquely to the cylinder 11.
