Title: Tiltable dozer in working traveling vehicle
Inventor: SOAN TADASHI
IPC: E02F3/85
Filed: 1994-03-30
Abstract: PURPOSE:To reliably perform excavating-earth pushing work in a desired posture by recognizing an inclined quantity of a blade to a machine body by an operator by graduations of a blade rear face plate and a mark of a guide body. CONSTITUTION:A rear face plate 21 of a blade 15 is slidably applied to a butting plate 20 integrally arranged on the front end of a vertically freely swinging front arm 11 of a traveling vehicle for excavating-earth pushing work, and is fitted to and locked on a guide body 22 arranged in a hook shape on the rear face plate 21 so that vertical swinging is guided. Angle graduations 23 are arranged on a rear surface of the guide body 22, and a mark 24 corresponding to the angle graduations 23 is arranged on a rear surface of the butting plate 20. While looking at a rear surface condition of the blade 15 from an operation seat, an operator reads the graduations 23 indicated by the mark 24, and recognizes an inclination of the blade 15 to a machine body, and extends and contracts a tilting hydraulic cylinder 17, and performs reliable excavating- earth pushing work in a desired tilt posture. Since an exclusive member is not separately required to recognize the inclination, the number of part items is not increased.

Title: Displacement measuring device
Inventor: MURAKAMI FUMIO
IPC: G01B11/24
Filed: 1991-03-26
Abstract: PURPOSE:To accurately detect displacement without a mechanical mobile mechanism by making two polarized components with a small difference in optical path length by way of double refracting a reflected light from a sample surface, and by calculating displacement amount of a sample by way of gaining a difference between reflected light intensities of both of the two components after separating them. CONSTITUTION:An outgoing light 2 of a light source 1 passes a beam splitter 5, converges through an objective lens 3 and makes a light spot on the surface of a sample 4. A reflected light 6 passes the objective lens 3, reflects through the beam splitter 5, only a specified polarized component passes through a polar screen 7, passes a double refraction plate 8 with an optical axis with a specified angle, causes a small difference in optical path length, passes a pin hole filter 9, separated through a polar separation screen 10, and both of separated lights are respectively photoelectronically transconducted and sent to an arithmetic unit 15. When one of the polarized components is image-formed accurately at the position of the pin hole filter 9, another image-formation face is slipped, reflected light amount (a) passing the pin hole filter 9 shows the maximum value and reflected light amount (b) comes to be a>b. A displacement signal 16 is obtained by way of computing (a-b)/(a+b) by the arithmetic unit 15. Consequently, it is possible to accurately detect the displacement amount.

IPC: G01S17/10
Filed: 1988-04-06
Abstract: PURPOSE:To make it possible to maintain the responsivity of an avalanche photodiode (APD) stably, by counting the number of pulses of the output of a first comparator, and outputting a control signal when the counted value reaches a specified value. CONSTITUTION:A bias voltage whose value increases with time is applied to an APD 5 from a bias circuit 6 before pulse laser light is emitted. Noises generated in the APD 5 are detected by a first comparator 8. The output of the comparator 8 is inputted into a first counter 16, and the number of pulses caused by the noise is counted. Data 18 of a specified counting threshold value are inputted into the counter 16 from a constant circuit 17. When the counted value of the number of the pulses reaches the data value 18, the counter 16 outputs a control signal 14 to the bias circuit 6. Thus, the increase in bias voltage is stopped. In this way, the responsivity of the APD can be maintained stably.
