Title: Direction-selective light-shielding body
Inventor: HONDA MAKOTO
IPC: G02B5/00
Filed: 1980-02-09
Abstract: PURPOSE: To form a body which occludes light selectively, by forming unevenness on a base surface at different angles to the reference surface of the base and by making at least one-side surfaces of respective couples of surfaces into light-absorptive surfaces.  
     CONSTITUTION: On the surface of base 1 of a transparent material, such as glass and plastics, many surfaces differeing in angle to reference surface 11 are formed in parallel. Light-absorptive layer 2 is provided on at least the one-side surface of each couple of the surfaces by metal vapor deposition, etc. Light incident to this light-absorptive layer 2 is intercepted as shwon by the arrow, and that incident to the other is transmitted to the reverse surface via base 1.

Title: Mechanism for detecting jam of paper feeding device
Inventor: KOYAMA SADAMI
IPC: B65H7/06
Filed: 1988-01-26
Abstract: PURPOSE:To accurately detect jam in a paper feeding device used for an electrostatic plotter, etc., by causing a sheet of paper to deflect and enter a recessed portion provided on a paper feeding face and operating a sensor in the recessed portion at time of the occurrence of jam. CONSTITUTION:While a recording paper 5 is being sent on a paper conveying face 2a in the arrow direction, no pressure from the recording paper 5 is applied to a leaf spring 4 keeping the front of the light receiving element 10 of an optical type object detector open. If a jam phenomenon occurs instead of the recording paper 5 causing deflection, the recording paper 5 presses the inclined face 4b of a leaf spring 4 downward due to the elasticity thereof. Thereupon, the end portion of the bent portion 4a of the leaf spring 4 interrupts the front of the light receiving element 10 and the optical type object detector detects the occurrence of jam in the sending action of the recording paper 5. The control portion of an electrostatic plotter stops the feeding of the recording paper 5 based on tie detected signal of the optical type object detector while operating an alarm. Also, a light emitting element 8 and the light receiving element 10 constitute a sensor.

Abstract: PURPOSE:To enable increase in accuracy over a wide range by disposing a light emitting element and photodetector in such a way that the light emitted from said element passes through the fixed 1st polarizing filter and the 2nd polarizing filter which is freely turnably attached. CONSTITUTION:When turning torque is applied to a fulcrum shaft 3, a polrizing filter 6 turns as well but a filter 5 is fixed and therefore the angle between the absorption axes of the two polarizing filters changes according to the turning amt. of the shaft 3. The transmittance of the light from a light emitting diode 1 to a phototransistor 2 passing through the two polarizing filters is max. when the angle between the absorption axes of the respective polarizing filters is zero and said transmittance is min. when said angle is 90 deg.. The transmittance is smaller as the angle between the two absorption axes is larger at the intermediate thereof.

Abstract: PURPOSE:To simplify the inserting work of nut into molding as well as make easier the removal of molding by a method in which the inflow of resin into the screw hole of nut is prevented by a bolt, and the bolt is removed through the threaded portion of the molding. CONSTITUTION:A bolt 14 having a length similar to the width l of a molding 10 is set, along with a nut 13 screwed into the threaded hole 12 of nut 13, into a cavity for forming the molding 10 injection. Also, the bolt 14 has a tap form, having a threaded portion to be screwed with the the thread of the nut 13 on its periphery and a dent 16 with a groove 15 radially extending from almost its central portion on its one end side. Thus, when injection molding is made under the condition that the bolt 14 is beforehand screwed with the threaded hole 12, the inflow of resin for the molding 10 into the threaded inner wall of the screw hole can be avoided by the connection between the bolt 14 and the screw hole 12, and therefore, no adherence of the resin to the inner wall side of the screw hole 12 occurs even after removing the bolt 14.
