Title: Control method for telephone set
Inventor: MURATA AKIHISA
IPC: H04M1/00
Filed: 1985-05-10
Abstract: PURPOSE:To simplify the complicated operation of a telephone set by placing a generating source such as infrared ray or ultrasonic wave and its reception section on a face opposed to the operator, detecting the infrared ray or ultrasonic wave reflected from the ace of the operator to control the telephone set. CONSTITUTION:An infrared-ray generating section 5 and an infrared-ray reception section 6 are placed at the lower side of a speaker with some distance and the desired function of the telephone set is controlled depending on whether the infrared ray reflected from a proximity object is to be detected by the section 6 or not. When the incidence of the reflected infrared ray to the reception section 6 is intermitted continuously for a prescribed time, the holding state is attained automatically and when the incidence of the infrared ray is detected by the reception section 6, the holding is released immediately. Thus, the holding state is attained automatically in response to the operation of the operator parting a handset from the ear and the mouth and the holding is released when the handset approaches the face again. Thus, the trouble of the operation of a holding button on each occasion is relieved.

Title: Laser measuring apparatus and stage apparatus or aligner having the apparatus
Inventor: INOUE MITSURU
IPC: G03F7/20
Filed: 1995-04-26
Abstract: PURPOSE: To obtain a stage apparatus which can measure position of a stage in a wide range with high accuracy and position the state highly accurately by setting an adjusting mechanism varying a beam diameter without interrupting a laser light. CONSTITUTION: A zoom-type beam expander as a beam diameter-adjusting means is constituted of a convex lens 2, a concave lens 3, a convex lens 4, feed screws 5, driving levers 6 and motors 7. When a driving instruction is given to each motor 7 from a controller 8, the feed screws 5 are rotated, thereby, the lenses 2, 3 are moved in a direction of an optical axis by the driving levers 6. The beam diameter can be changed continuously without shutting an emitted laser light by adjusting relative positional relationships of the lenses 2, 3 and 4. The beam diameter is reduced when the optical axis is adjusted, and thereafter the beam diameter is increased in accordance with the limit of strokes or rotating amount. Accordingly, it becomes unnecessary to detect an origin of a length-measuring means.
