Title: Optical information reproducing device
Inventor: AKAHORI HIROSHI
IPC: G11B7/135
Filed: 1986-01-28
Abstract: PURPOSE:To obtain good reproduction SN ratio by making a peripherals area in near field or a paraxial area in far field of reflected luminous flux from a signal face not enter into the light sensitive face of photodetector. CONSTITUTION:A slit 8 is provided near the focus of a condenser lens 7. Light emitted from a semiconductor laser 5 is made to parallel light by a collimator lens 6, and converged by an objective lens 3 and irradiated in spotlike form on the signal face of an information recording medium 1. Light reflected from the signal face is made to parallel light by the objective lens 3, converged by the condenser lens 7 and enters the photodetective face of a photodetector 9.

Title: Manual operating device for elevator hoist
Inventor: OKADA KOJI
IPC: B66B5/00
Filed: 1990-01-29
Abstract: PURPOSE:To reduce the cost with a simple structure and enable the manual operation of a hoist from outside of an elevator passage by pushing the elastic member with an operating member to give the elasticity of the rotation to a rotating member unified with a rotary shaft through the elastic member. CONSTITUTION:The brake is cancelled by an operating member, and a projection is pushed through an elastic member 45 to give the elasticity of the rotation to a rotating member 42. Since a worm reduction gear 9 usually having a self- lock mechanism does not transmit the force of the cage side to the motor 8 side, a rotary shaft 8a is not rotated with only cancellation of the brake. But, when the elasticity of the rotation is given to the rotary shaft 8a through the rotating member 42 in the rotating direction at the time of lowering the cage, the lowering force of the cage with its dead weight is reversely transmitted to the motor 8 side to rotate the rotary shaft 8a. As a result, the cage can lower continuously with the dead weight.

Abstract: PURPOSE: To obtain a quantitative container which eliminates the need to provide a slide box with a knob, is of a simple quantitative structure, and is designed in consideration of environment, for example safety and disposal, by providing part of an outer box with a notch for exposing the slide box. CONSTITUTION: With a slide box B moved to the left end of the hollow (a) of an outer box A, the notch hole 8 of the slide box B and an opening 19 coincide, and two of the items C in the outer box A enter a measuring chamber (b). When the slide box B is moved to the right by pushing an part exposed from a notch 101, the right end of the slide box B strikes against the side 2 of the outer box A, so that it stops. At this time, the two items are easily separated from remaining items C stored in the outer box A, because the body wall of the upper face of the slide box B levels off the items. When the slide box is in a stopping position, on the other hand, the notch hole 20 of the slide box B and the discharge opening 7 of the outer box A coincide, therefore the two items can be taken out simply by tilting the outer box A.
