Title: Erroneous-operation monitoring device for changed-amount measuring apparatus
Inventor: YASUDA MAMORU
IPC: G01B7/00
Filed: 1983-02-22
Abstract: PURPOSE:To ensure the detection of the erroneous operation of an encoder due to the shortage in voltage, by providing an error-message output circuit, which is operated by the output from a voltage-shortage detecting circuit. CONSTITUTION:A reference voltage VL, which is required for the normal operation of an encoder 10, is preset. When an output voltage Vcc of a main power source circuit 14 becomes lower than the reference voltage VL, a detected voltage shortage signal S is outputted from a voltage-shortage detecting circuit 26. When the detected voltage shortage signal S is inputted, a semiconductor element 24 outputs an H level signal, which represents an error message, from a terminal Q of the element 42. The H level signal is continuously outputted until a power source switch 12 or an auxiliary switch 12a is turned OFF, and the error message is continuously displayed.

Title: Side slope stabilizing work
Inventor: TAKEDA KIHEE
IPC: E02D5/80
Filed: 1995-01-25
Abstract: PURPOSE: To prevent a pressure receiving board from settling and minimize a grounding area of the pressure receiving board by fixing the pressure receiving board with the head of an anchor installed on a side slope and installing a projecting body on the grounding surface of the pressure receiving board and producing a friction resisting force between the projecting body and a natural ground. CONSTITUTION: A pressure receiving board 3 is fixed with the head of an anchor 2 installed on a side slope 12 where the pressure receiving board 3 is pressed against the side slope 12. A projecting body 4 is installed on a grounding surface 31 of the pressure receiving board 3. This projecting body 4 is immersed into the natural ground. Since a live load acts on the pressure receiving board 3 installed on the side slope 12 of a weak natural ground 1 with a force produced by the shrinkage of the anchor 2, the pressure receiving board 3 tends to sink, if the side slope of the natural ground has a weak bearing power of soil, and the side slope 12 may cause a landslide.  In this case, a friction resistance is produced between the surface of the projecting body 4 immersed in the natural ground and the surrounding natural ground, which makes it possible to inhibit the pressure receiving board 3 from settling due to the friction force of the bearing power of soil reinforced with this friction resistant force.

Abstract: PURPOSE:To quickly start driving of an actuator by outputting pulse signals with wider pulse width to a flow-rate control valve before pulse signals with pulse width which is required to obtain a desired opening, is outputted when the hydraulic actuator is driven. CONSTITUTION:A control mechanism 6 outputs pulse signals with wider pulse width before intermittent pulse signals with pulse width which is required to obtain a desired opening, when a hydraulic actuator 12 is driven from its non- operating condition based on signals from a level setter 3 setting the level of an operating device 1 with respect to a car body and a level detector 5 detecting the rocking angle of a lift arm 4. Electric current signals of comparatively high amperage are therefore supplied to a lifting or a lowering flow-rate control valve 9 and 10 at the early stage of control through power transistors 7 and 8 so that the control valves 9 and 10 can be operated at the early stage against the inertia force of a spool or the viscosity of working oil. By this constitution, driving of the actuator is quickly started, and concurrently a hydraulic motor can thereby be precisely controlled in operating speeds.
