Abstract: PURPOSE:To assure position fixing of a seal member by forming a rib projection face on the inside of a case in the form of taper, forming a notch member at a part of a mechanical part corresponding to the rib, and providing a larger rising part than the inner diameter of the seal member, at a portion of this notch part corresponding to the seal member. CONSTITUTION:In inserting a mechanical member 2 into a case 3, a seal member 10 to be arranged between them is pressurized to a mounting part by a rib 4 on the inside of the case 3. In this case, the seal member 10 tends to shift in the moving direction of the case 3 from the mounting part, but this shift is blocked by a rising part 11 at a notch member 9 of the mechanical part 2. Further, the seal member 10 tend to shift on the open side of the case 3 from the mounting part, but the shift is blocked by the tapered rib 4. It is thus possible to surely position fix the seal member at the specified mounting part, and to prevent leak of lublicant from the mechanical part 2.

IPC: G01C3/06
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To measure an accurate distance quickly by providing a control means repeating the distance measuring operation for any one of two sensors when the correlation reliability obtained therefrom is lower than a reference level thereby preventing a light receiving image from being missed even for a sensor array remote from a light projection means. SOLUTION: When a decision is made that the correlation reliability is low, the window 105a of a sensor array 105 is not shifted in case of light receiving images 107, 108, for example, but the window 104a of a sensor array 104 is shifted to the left before repeating the measurement of distance. Since the light receiving images 107, 108, are confined within the windows 104a, 105a, normal sensor signal outputs 109, 110 can be obtained. A decision is made whether both windows are shifted or only one window is shifted based on the arrangement of optical system and the range to be measured.

IPC: H01P5/04
Filed: 1986-01-30
Abstract: PURPOSE:To obtain a microwave switch with a low loss by connecting a 0/pi reflection type phase shifter between an input hybrid and an output hybrid via a hybrid for phase changeover. CONSTITUTION:A signal inputted from a terminal 1a of the input hybrid 1 is inputted to a terminal 10a of the output hybrid 10 from a terminal 1c via a fixed phase shifter 9. A signal outputted from a terminal 1d of the input hybrid 1 is inputted to a hybrid 11 and inputted to a terminal 10b of the output hybrid 10 while being outputted from a terminal 11a. Since 0/pi reflection type phase shifters 2, 3 are connected to terminals 11d, 11c of the hybrid 11, a drive circuit 4 outputs a signal to a terminal 10c of the hybrid 10 when the phase shift is zero so as to make the output of the terminal 10d zero. In shifting the phase into pi, the relation above is conversed. The transmission loss of the fixed phase shifter 9 is 0dB and the phase shift is 2theta-3pi/2, where theta is the phase shift of the hybrid.

IPC: C21D1/09
Filed: 1986-01-30
Abstract: PURPOSE:To uniformly harden a sliding surface having curvature without melting the central part by placing a medium which shields or half shields light at the center of the curvature and carrying out laser beam hardening. CONSTITUTION:For example, the push rod receiving part 2 of a steel tappet 1 is hardened by irradiating laser light.
