Title: Mimic tooth
Inventor: FUKADA KUNIO
IPC: G09B23/28
Filed: 1988-12-08
Abstract: PURPOSE:To clearly understand whether a cutting method (cutting tool operating technique) which a trainee learns hitherto is proper or not and whether the formation of a root tube is successful or not by constituting a mimic tooth in which the wall surface of the root tube is covered with a colored film and the outside surface of the mimic tooth is covered with a opaque film. CONSTITUTION:The wall surface of a root tube of a mimic tooth 1 is covered with a colored film 5, and the outside surface of the mimic tooth 1 is covered with a opaque film 6. Accordingly, a trainee cannot recognize where a cutter- edge of a file is put in the course of cutting the wall surface of a roof tube 2 by the opaque film 6 which covers the outside surface of the mimic tooth, but as for the part against which the cutter-edge is pressed actually and which is cut, the colored film 5 is peeled off, and on the contrary, as for the part against which the cutter-edge is not pressed and which is not cut, the colored film 5 remains behind. Subsequently, after training is ended, the opaque film 6 is wiped off by using a solvent so that the root tube 2 can be viewed. In such a way, the cut surface and the non-cut surface can be recognized at a glance, and it can be understood that there is a large recognition error in a conventional cure which the trainee uses hitherto.

Title: Fluid pressure suspension device
Inventor: OOMITSU TAKASHI
IPC: B60G17/015
Filed: 1988-12-08
Abstract: PURPOSE:To enhance compliance to changes in the road surface condition in a fluid pressure suspension device for car by partitioning a cylinder into a main chamber with a piston and an aux. chamber, changing the volume of main chamber with motion of an aux. chamber piston, putting inside of the aux. chamber into high or low pressure, putting it in communication with the main chamber, and thereby varying the spring constant. CONSTITUTION:When an aux. chamber piston 6 retreats in its maximum, the volume of a main chamber 3 maximizes and the spring constant minimizes to provide the most flexible suspension. In this condition, an air pump 11 is operated, and a valve 8 is closed to accumulate an air pressure higher than the main chamber 3 in an aux. chamber 4. Then the valve 8 is switched to supply the high pressure air in the aux. chamber 4 to the main chamber 3, and thus the spring constant is increased quickly. The aux. piston 6 is moved to the left by a motor 10 to decrease the volume of the main chamber 3, which provides a stiff suspension. Following the procedure oppositely provides a flexible suspension. This constitution enhances the compliance to changes in the road surface condition.

Title: Cpu run away detection circuit
Inventor: TSUNETOMI HIROSHI
IPC: G06F11/00
Filed: 1990-11-16
Abstract: PURPOSE:To rapidly and surely detect the run away of CPU by making CPU execute a program, monitoring the execution order and outputting a detection signal or a time-up signal, which is generated earlier, when the execution order is detected not a right order. CONSTITUTION:When CPU executes only OUT instruction without executing a specified instruction by its run away, etc., an output f of an undergate 5 becomes active and a detection signal f is generated as an output b of Q of 1 instruction window generation circuit 16 is '0'. When a specified instruction or OUT instruction is not executed, a timer circuit 1 continues counting operation and outputs a time-up signal h. Therefore, an OR-gate 7 outputs the time-up signal h or the detection signal f, which is generated earlier, to 11 for CPU reset output. Then, CPU receives this signal as a reset signal or an interruption signaland executes proper processing such as initialization, etc. Thus, the run way of CPU is rapidly and surely detected without loading a program.
