Filed: 1988-07-08
Abstract: PURPOSE:To achieve a reduction in logic validation work and a simplification of circuit debugging work by inputting an input test pattern and an output value into a logic validation aid symbol as done into a logic circuit to be tested. CONSTITUTION:An input test pattern is registered into an input test pattern registering section 12 and the operation of a logic circuit to be tested is described by a high level language in an expected value generation module 21. In a logic circuit 11 to be tested, a test pattern from the registering section 12 undergoes a logical simulation and the results are sent to a logic validation aid symbol 14 to calculate an output expected value of the test pattern from the registering section 12 and the results of comparison with an output value from the circuit 11 are shown on a logic validation results display section 13.

Title: Annunciator of parking brake
Inventor: SUZUKI YOSHITAKA
IPC: B60T17/22
Filed: 1983-09-16
Abstract: PURPOSE:To prevent accidents by generating different alarms respectively when a vehicle retreats along a slope during parking even if parking brake is operated or when the vehicle starts as the parking brake is applied. CONSTITUTION:When a vehicle is parking on a slope and retreats even if parking brake is applied, a vehicle speed sensor 1 generates the detecting signal which is compared with reference voltage V1 through F/V converter 2 by a comparator 3. When said detecting signal voltage exceeds V1, the comparator 3 generates the H signal to AND circuit 11. Since a parking brake switch 5 is turned on, the AND circuit 11 generates the H signal to a buzzer controlling circuit 12. Also, as an engine is in idling, the signal of low level from a rotational frequency sensor 8 is sent to the input of the buzzer controlling circuit 12 which operates continuously a buzzer 13. When the vehicle starts and travels as the parking brake is applied, the control circuit 12 operates intermittently the buzzer 13 with HV level signal of the sensor 8.

IPC: G11B17/04
Filed: 1983-09-16
Abstract: PURPOSE:To improve reliability of the device by installing an expander mechanism which is movable in the insertion direction of the record case, and installing, in the expander mechanism, a shift stopping member which can be displaced a shift stopping position, which stops the shift of the mechanism and a shift stopping release position permitting the shift of the mechanism. CONSTITUTION:A slide plate 208 as a shift-stopping member slides only in the Z1 and Z2 directions by pins 209 and 210 which are studded on a base 207 and a slot 208a. A case 2 is forced into an expander member 215 in an X1 direction, and when contacting the expander member, the case 2 is expanded the slanting side of the expander member 215. When the case 2 advances in the X1 direction, the lower part of the case 2 moves from the expander member 215 to a supporting member 216 and then is further expanded. An end of the case 2 comes into contact with an abutted end 217b of a latch 217, and the latch 217 moves around in the Y2 direction. At the same time an engaged end 217c of the latch 217 enters a hole 13 of the case 2 and detains the case 2. Further when the case 2 is forced in, the slide plate 208 can slide in the Z2 direction, that is, at the shift stopping release position, thereby allowing an expander mechanism 200 to move in the X1 direction together with the case 2.

IPC: B23Q3/18
Filed: 1989-07-05
Abstract: PURPOSE: To ensure easy centering for an inner/outer face grinding machine by changing the magnitude of force with the movement of the axis of a workpiece to the rotation axis of a chuck to successively strike the workpiece with centering means. CONSTITUTION: When a workpiece W is mounted on a magnetic chuck 10, a control unit 100 drives on/off a three-way air solenoid valve 67 while rotating a magnetic chuck 10 to seccessively hammer the workpiece W several times with an air pressure centering hammer mechanism 58 for centering means 56 for centering. In this case, the magnitude of striking force is changed with an eccentric distance, detected by an eccentric distance sensor 90, for the center axis G of the workpiece W to gradually moved to the rotating axis R of the chuck 10. That is, an air pressure regulator 66 is controlled to reduce air pressure so that the striking force can be smaller. In this way, work for centering the workpiece on the magnetic chuck or others is automatically done in a short time.

IPC: G01N3/00
Filed: 1986-07-22
Abstract: PURPOSE:To reduce cost by the use of a simple device and to shorten a testing time, by erecting several pieces of anchors on a lower plate and allowing said anchors to pierce through a base plate and a top plate so as to make both plates slidable. CONSTITUTION:After a mixture of cement and the ground is leveled, a lower plate 1 and anchors 2 are embedded in the ground so that the anchors 2 are embedded almost by half and a base plate 3 is placed on the surface of the ground, and a hydraulic jack 8 and a strength measuring device 9 are interposed between the base plate 3 and a top plate 4. After the ground is solidified, when hydraulic oil is supplied to the jack 8 by a hydraulic pump 10, the top plate 4 placed through the strength measuring device 9 at the upper part of a rod is pushed upwardly by the hydraulic jack 8 but prohibited from shaking upwardly by a detachment preventing stopper 7. By this mechanism, upward force acts on the lower plate 1 while downward force acts on the base plate 3 and the soil positioned between both plates 1, 3 is pressed and destructed by the action of both plates 1, 3. By measuring the force when destruction is effected by the strength measuring device 9, strength can be known simply.
