Filed: 1981-06-17
Abstract: PURPOSE: To protect a table of a data processing system and to obtain a high- quality program, by using a key code producing means and a checking means.  
     CONSTITUTION: A source program is converted into a program 13 of execution type comprising a table 14 and an instruction executing part 15 through an interpreting circuit 12. During this process, the circuit 12 sets the same key number N corresponding to a key code B32 of the table to a key code A24. When the program 13 is executed, the part 15 fetches the table of a code B32=N among the tables corresponding to a code A24=N into a main storage. Then the coincidence between the code A24=N and the code B32 is checked through a key checking circuit 42. When no coincidence is obtained, the process is jumped to an access inhibition processing circuit 44. While the program 13 is executed via a reset processing part 43 to the executed program when the coincidence is obtained.

Title: Device for monitoring taking-out of molding material from casting
Inventor: JOHANN PREISINGER
IPC: B22D29/00
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To enable the effective and simple monitoring for securing the accurate taking-out of a mold by providing one piece of an exhaust air introducing pipe or an exhaust air storage disposing a pressure monitoring gage therein in a hammer unit. SOLUTION: Compressed air is fed to a compressed air supplying pipe 5 and then, the hammer head 7 develops a striking movement and the exhaust air is exhausted through an exhaust air conduit 6. The pressure monitoring gage 9 is disposed with some distance from the hammer unit 4 and further, from an opening end part 8 and connected with an electronic assessment circuit through an electric connecting cables 10. The compressed oil vigorously pulsates at the time of exhausting from the hammer unit 4, but since the exhaust air conduit 6 is long, the pulsation is weakened at the tip part. Since the pressure monitoring gage 9 is disposed with the sufficient distance from the opening end part 8, the pulsation can sufficiently be detected even at the opening end 8.  In the case that the hammer head does not contact with a casting, the pulsation can be detected with the increase of working frequency.

Title: Ac zero cross switch
Inventor: NAKAYAMA KATSUYUKI
IPC: H03K17/13
Filed: 1978-08-01
Abstract: PURPOSE:To increase the reliability, by reducing the number of components in the zero cross function circuit and decreasing the switching element to one, through the use of photo Triac. CONSTITUTION:In the zero cross function circuit 33, the voltage across the AC input terminals C and D is divided with the resistors 24 and 25, and it is fed between the base emitter of NPN transistor 23 and PNP trsnsistor 26. When the voltage across C and D reaches a given voltage, the transistor in forward bias is conductive depending on the polarity to make the part between the gate T1 of the photo Triac 22 and the electrode less than the gate trigger voltage to block the conduction of the photo Triac 22 by photo signal 27. Accordingly, when the control signal is fed to the control input terminals A and B, if the absolute value of the voltage across C and D is not less than the specified voltage, no photo Triac 22 can be conductive to constitute the switch having zero cross function.

Title: Error detecting circuit
Inventor: SHIMOI KOUICHI
IPC: H03K5/19
Filed: 1979-07-25
Abstract: PURPOSE:To ensure the hysteresis property to the error detection in a simple constitution, by having more number of the error detection pulses in the case of the output of the alarm than in the case of the cancel of the alarm. CONSTITUTION:A number of error detection pulses are applied within the time shorter than the charging time constant decided by resistances R1, R3 and R4, and the terminal voltage of capacitor 1 attains less than the threshold level of inverter INV2. Thus the output of INV2 turns to ''1'', and accordingly the FF is set with application of clock CL with terminal Q turned to ''1'' to deliver the alarm through terminal OUT. After this, both putputs of INV1 and NAND turn to ''0'' with application of the error detection pulse. And capacitor C1 discharges via diodes D1 and D2, and accordingly the terminal voltage lowers suddenly. Accordingly, Pe1< Pe2 is secured between error detection pulse number Pe2 which delivers the alarm and pulse number Pe1 which cancels the alarm, thus ensuring the hysteresis property.
