Abstract: PROBLEM TO BE SOLVED: To improve the degree of freedom of equipment installation by using an infrared ray signal transmitter-receiver whose optical axis direction is able to be deflected within a prescribed range so as to retrieve a direction in which reception strength is maximized. SOLUTION: An infrared ray transmission reception unit 100 is made up of a 1st infrared ray signal transmitter-receiver 10 having a sharp directivity and 2nd infrared ray signal transmitter and receiver 13, 14 having a wide directivity. The 1st transmitter-receiver 10 is mounted on a frame driven by a motor so as to change its optical axis direction in a prescribed range in vertical and horizontal directions. The infrared ray transmission reception unit 100 is mounted respectively on a desk-top computer and a portable computer, between which infrared ray communication is executed. A transmitter side wide directivity signal transmitter 13 sends an ID signal. A receiver side receives the IS signal by a wide directivity signal receiver 14 and a wide directivity signal transmitter 13 sends an ID signal of the receiver side.  Then the 1st signal transmitter-receiver 10 with a sharp directivity scans the directions of the received signal to search a direction in which the signal reception strength is maximized.

IPC: G01R1/067
Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To secure a contact resistance stably and to improving wear resistance property and machining accuracy by forming the shape of a tip contact part at first to fourth plane parts and obtaining stable continuity. SOLUTION: With a tip shape, first, second, third, and fourth plane parts 36, 37, 38, and 39 are formed, so that plating cannot be released easily, and the tip of a contact pin cannot be deformed, worn out, or oxidized, thus obtaining the contact pin of a semiconductor-testing device with stable continuity. Also, since a contact surface is flat, a large contact area can be obtained. As a result, centered resistance cannot occur easily, contact resistance is small, and continuity stability is superb. Further, the plane parts 36-39 are provided at each tip of first to fourth tip contact parts 32-35 so that the position in axial direction of the contact pin is equal and so that the plane parts can be provided while they orthogonally cross the axis of the contact pin.  Therefore, the height of each tip is aligned uniformly for machining easily, thus reducing contact scattering on contacting the pad.
