Title: Optical reader
Inventor: NAKADA YASUO
IPC: G03B27/50
Filed: 1985-04-03
Abstract: PURPOSE:To easily correct the distance between an original and a lens array by arranging a parallel plane plate on an optical path connecting an image forming element and a reading element and varying the length of the optical path substantially. CONSTITUTION:Lens arrays 2a and 2b for image formation are arranged symmet rically about a field lens array 2c between the original 1 brought into contact with the top surface of contact glass 6 and the photodetection surface 3 of a photodetector. Then, the transparent parallel plane plate 4 made of glass, etc., is arranged between the array 2a and original 1. The arrangement of the plane plate 4 which has thickness (d) and a refractive index (n) varies the length of the optical path between the array 2a and original 1 by DELTAL=L(1-na/ n)d, where na is the refractive index of air. For the purpose, plural kinds of plane plates 4 which differ in thickness are used and when the distance between the array 2a and original 1 becomes longer than the distance between the array 2b and photodetection surface 3, a plane plate 4 having thickness (d) correspond ing to the distance DELTAL is arranged. Consequently, the optical path is corrected from a broken line to a solid line to equalize both distances to each other substantially.

Filed: 1979-06-05
Abstract: PURPOSE: To improve the yield and efficiency of pipe making process by installing a metal pipe in the mold, pouring molten metal in the mold and metal pipe then removing the cast ingot from the inside of the metal pipe.  
     CONSTITUTION: Pouring of the specified molten metal 7 by bottom pouring is done into a mold 1. At the time when the molten metal 7 rises along the outside surface of a pipe 10, it evaporates the resin 13 coated on the outside surface of the metal pipe 11 and therefore it springs out the impurities existing on the molten metal 7 surface thereby preventing the bonding failure after freezing. Next, the pouring is stopped before the molten metal 7 reaches the top end of the inside coating pipe 10, and a separating ball 20 is charged immediate after the pouring. Further, a pull bar 6 is dipped and held as a jig for making the removal of the cast ingot after the freezing easy, in the molten metal 7 at the inner side of the inside surface coating pipe 10. Upon completion of the freezing in this state, the cast ingot in the inside surface coating pipe 10 is pulled, whereby the hollow composite metal cast ingot is produced.

Filed: 1982-04-30
Abstract: PURPOSE:To improve a speed change response characteristic, by temporarily increasing a line pressure higher than at normal time under a condition necessary for a rapid speed change to prevent a V-belt from slipping at the rapid speed change. CONSTITUTION:When a speed change operating mechanism 112 is moved largely or rapidly to any of the directions, pressure of oil in pulley cylinder chambers 28 and 44 is changed, before a speed change is started, a spool 152 is moved to communicate a port 122g to a port 122f or 122h. In consequence, oil in a port 118i of a line pressure regulating valve 102 is discharged through an oil path 1,001, the ports 122g and 122f or 122h. Accordingly, leftward force applied to a spool 132 of the valve 102 is decreased, and line pressure of a port 118h is increased so as to compensate a decrease of said force. That is, the line pressure increases at a rapid speed change to improve a speed change response characteristic.
