IPC: B21F35/02
Filed: 1984-05-14
Abstract: PURPOSE:To form a spring having spiral spring parts at both ends of the straight part by letting off wire rods while holding said rods by means of a pair of holding rolls and forming spirals from both ends of each wire rod by means of forming rollers, guide bodies and pitch bars. CONSTITUTION:The wire rods 27 are delivered by each piece from a stacking part 5 and while the wire rods 27 are grasped by grasping arms 61, both ends of each wire rod 27 are formed with bent parts. The arms 61 are then rotated about 270 deg. and both ends of the rod 27 are inserted into a pair of the holding rollers 135 provided to a pair of movable bodies 87. The middle part of the rod 27 is grasped and fixed by a grasping mechanism 205. The rod 27 is held between the rollers 135 by a lifting cylinder 143 and the bodies 87 are brought into proximity to each other to let off the rod 27 from the rollers 135. Both ends of the rod 27 are spirally bent by the rollers 153. The diameter of the spirals is determined by guide bodies 151 and the rollers 153. The spirals are successively formed by determining the pitch by the pitch bars 155.

Title: Variable resistor and position detector using same
Inventor: INABA RITSUO
IPC: H01C10/30
Filed: 1989-04-14
Abstract: PURPOSE:To remarkably enhance the precision of the title variable resistor by a method wherein, a variable resistor using resistors and a brush, the resistors are provided in parallel with one another. CONSTITUTION:One resistor 1 in contact with a brush and other resistor 2 are provided in parallel with each other. That is, of the applicable two sets of resistors, one type of resistors 2 seek for the precision while the other type is a resistor 1 of a conventional constitution. The resistors 2 seeking for the assurance of precision are not necessarily required of the continuous resistance distribution and conventional fixed resistance affixed thereto (the precision of position where they are affixed is assured to some extent) can be used instead. In order to assure the overall resistance value precision, the resistors 2 seeking for assuring the resistance value precision are supplied with more current than that of the resistors for picking up voltage so that the former resistors may be used as a low current circuit to facilitate the enhancement of precision. At this time, the resistors 2 seeking for assuring the absolute value precision of angular precision of resistance value, positional precision and resistance value can be used thereby enabling the precision of the title resistor to be enhanced notably.

Title: Collapsible barrel type single lens reflex camera
Inventor: ISHIGURO YASUO
IPC: G03B17/04
Filed: 1979-07-27
Abstract: PURPOSE: To make construction compact and cost low by moving a mirror upward as desired and enabling the lens barrel to be housed in an empty space thereby.  
     CONSTITUTION: The collapsion operation takes place like this. A lens barrel 21 is given left turn by a mirror pressing spring 23 as the contact face 21a makes engaging contact with the projecting part 22c of a mirror coupling ring 22. The meshing of a click stop spring 24 and a click groove 21b is released when the lens barrel 21 is manually turned left. As a result of this left turn, the lens barrel 21 stops in the position where each of projecting parts 21c 1 , 21c 2 , 21c 3  can go into each of the recesses 27a, 27b, 27c of a body flange 27. Such left turn of the mirror coupling ring 22 causes a mirror arm 22a to press the 1st arm 5a which then turns a mirror lever 5a left, and this causes the lever 5 to turn the mirror 1 left against a mirror spring 3, thereby moving the mirror 1 upward. If the lens barrel 21 is pushed in after this, it is housed in the space after the mirror 1 has ascended, thus assuming a collapsed state.
