Title: Emergency position detector
Inventor: TANAKA NORIO
IPC: G01R31/08
Filed: 1980-09-16
Abstract: PURPOSE:To enable the operating position to be made clear, by a method wherein resistors having their respective rsistance values are connected to respective contacts in parallel, and the resistance values are measured in a signal-receiving part. CONSTITUTION:When the contact of sensors 2-7 are all closed, one potential of a comparator 16 is the ground potential, whereby all of the contacts are judges to be closed. As an example, when the sensor 5 is opened, a voltage drop occurs owing to a resistor 12 (8XROMEGA). This potential appears on a signal line 8, becoming an input to the comparator 16. A control circuit 18, which is acutated by means of said input, varies a reference voltage 17 in order to detect the voltage drop due to the resistor 12. Because the resistance values of the respective sensors are different from each other, the sensors are also different from each other in, the voltage drop. Setting each resistance value to be an n-th power of 2 permits knowledge of which sensor has operated even when a plurality of sensors are in operation simultaneously.

Title: Manufacture of semiconductor device
Inventor: MATSUDA JUNICHI
IPC: H01L21/761
Filed: 1989-05-19
Abstract: PURPOSE:To obtain a semiconductor device high in density as compared with a conventional one by a method wherein wells are formed in a self-aligned manner. CONSTITUTION:A first and a second well, 12 and 13, are formed in a self-aligned manner through the intermediary of the same opening, and a third well 16 is formed in a self-aligned manner through the intermediary of a thermal oxide film 14 which is formed after the opening of an oxidation resistant insulating film 10 is adequately widened. As mentioned above, the wells 12, 13, and 16 are formed in a self-aligned manner, so that masks required for the formation of patterns can be reduced in number. As the first well 12 (or second well 13) and the third well 16 adjacent to it can be formed self-aligned with each other, the deviation of the masks induced in position alignment is not required to be taken into consideration. By this setup, the distance between the wells can be reduced to an optimal value, so that a semiconductor device of this design can be densely integrated as compared with a conventional one.

Title: Program checking system
Inventor: TAKEBAYASHI HAJIME
IPC: G06F11/36
Filed: 1983-07-12
Abstract: PURPOSE:To perform diagnosis whether a program is normal and whether programs are compatible among blocks by having the self-diagnosis of a CPU. CONSTITUTION:A CPU2 calculates the SUM value of a program stored in an ROM1 and compares the calculated value with a prescribed area of the ROM1 to check the presence of the SUM value. If the presence of the SUM value is confirmed, the corresponding version is printed by a printer 4. Then the version corresponding to the SUM is written to the version data save area of an RAM5. In case no SUM value exists in the prescribed area in the ROM1, an ROM error flag is set to print the SUM value and an error display. This action is repeated in the same way with ROM2 and 3 to decide whether the SUM value of each ROM is equivalent to the value stored in the prescribed area of the ROM1. Then the ROM error flag is checked to decide that either one of programs of ROM1-3 is faulty if said error flag is set. Thus an operation ends.
