Title: Reflective type photoelectric switch
Inventor: KANBE YOSHIAKI
IPC: G01S17/04
Filed: 1983-04-30
Abstract: PURPOSE:To prevent erroneous operation even with respect to an object to be detected comprising a mirror surface body, by providing light quantity control means for controlling an output circuit by discriminating whether the object to be detected comprising the mirror surface body is present or not in a detection area on the basis of the light quantity level of reflected light. CONSTITUTION:Laser beam is emitted to an object to be detected and reflected beam is detected by the beam receiving elements 20a, 20b of a position detecting means arranged to the beam collecting surface of a receiving optical system. The detected output is inputted to a distance measuring control means 5 and an output circuit is operated through a signal processing circuit 25. A beam quantity control means 7 is connected to the means 5 and compares the output of the amplifier G2 of the beam receiving circuit 21a of the means 5 and reference voltage divided by a resistor R5 and a detection area setting variable resistor VR2 to discriminate whether a nomally operale beam receiving signal is obtained or not and freely inhibit the input to the circuit 25 through an OR circuit. By this method, it can be discriminated whether the object to be detected comprising a mirror surface body is present or not in the detection area without erroneous operation.

Title: Movable sheave pressing-in mechanism of belt type stepless speed change gear
Inventor: UCHIKAWA YASUO
IPC: F16H61/26
Filed: 1982-05-07
Abstract: PURPOSE:To reduce the operating force of a speed changing pedal, by forming the link mechanism, which is connected to a pedal arm, a transmission rod, etc., into a four-point link mechanism. CONSTITUTION:A four-point link mechanism 10 consists of a motive lever 15, a relaying lever 16, and a following-up lever 17, and the motive lever 15 is supported pivotally on a pedal rotation shaft 13 so that the motive lever 15 is turned together with a pedal arm 14 as one body. The following-up lever 17 is formed turnably with a supporting shaft 17a as the fulcrum and has one end connected to a transmission rod 9, and the rod 9 is moved back and forth by turning of the following-up lever 17. Consequently, when a pedal 8 is stepped, the rod 9 is moved, and therefore, a pressing-in rod 12 connected to a speed changing arm 11 is turned and moved. Then, an input pulley-side movable sheave 1a is moved in the direction of speed increased. Thus, since the link mechanism is formed into the four-point link mechanism, the operating force of the speed changing pedal is reduced.
