Abstract: PURPOSE:To provide a malfunction preventive circuit of a computer for control capable of certainly prohibiting control of a device to be controlled by the computer for control while the computer for control is abnormal. CONSTITUTION:When a CPU 16 becomes abnormal and a clock pulse 10 continues in a low condition for more than specified time, a reset signal 14 in a high state is output from a reset generating circuit 23, a CPU monitor signal 7 comes to be in a low state and it is input to an AND circuit 6. Consequently, a transistor 5 comes to be in an 'OFF' state, and ignition of an ignition device 4 to expand an air bag is prohibited. As the CPU monitor signal 7 is in the low state even after the reset signal 14 is released, ignition of the ignition device 4 is prohibited. When the CPU 16 returns to a normal state and the clock pulse 10 is output, the CPU monitor signal 7 becomes high and it is input to the AND circuit 6. Consequently, it is possible to ignite the ignition device 4 in accordance with a collision judgment signal 8 from the CPU 16.

Title: Selecting method by adsorption of microorganism to mineral
Inventor: NAGAOKA TORU
IPC: C12P3/00
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To effectively and selectively separate pyrite from a mixed mineral by bringing microorganisms into contact with a mixed mineral to allow the microorganisms to adsorb on pyrite in the mixted mineral. SOLUTION: In a flotation process, the floating property of pyrite in a sulfide mineral is inhibited by sulfurous acid, and as a result, the pyrite is apt to be removed with the gangue. By using microorganisms for the flotation process to control the floating property of pyrite in a sulfide mineral, the pyrite which is very difficult to be separated can be removed without adding various kinds of flotation agents which require complicated operation or without adding a toxic reagent. The microorganisms used are not limited as far as they can selectively adsorb on pyrite and convert the surface property of the pyrite from hydrophobic into hydrophilic. Considering the high adsorption selectivity to pyrite in a mixed mineral, iron bacteria is preferable, and for example, a strain of thiobacillus ferrooxidans ATC 23270 can be used.

Title: Selective calling system
Inventor: HIRAO TAKASHI
IPC: H04M3/00
Filed: 1979-07-23
Abstract: PURPOSE:To avoid disconnection of the circuit at the unregistered station for the selective calling system in which an individual talking is carried out by the single communication channel and with the same frequency shared by a number of radio stations, by using the on-hook signal in common to the answer individual signal and the call individual signal which are used originally in different purposes. CONSTITUTION:Both the calling station and answering station under the busy state are registered previously in the switchboard sides 1-3 based on the call and answer individual signals which are allotted individually to all radio stations 71-7N. Then  this registration is cancelled by the on-hook signal common to all radio stations in order to secure the release of the circuit. In such radio circuit system, the call individual signal of the calling station or the answer individual signal of the answering station is transmitted along with the on-hook signal when the calling or answering station under the busy state and including the mobile station completes the talking. These signals are detected at the side of the switchboard. And only in case the  detected signal is identical to the signal of the calling or answering station, the release is given to the circuit.

Title: Peripheral circuit of nonvolatile semiconductor memory
Inventor: TANAKA SUMIO
IPC: G11C17/00
Filed: 1983-05-26
Abstract: PURPOSE:To reduce the size of a transistor (TR) with no deterioration of performance due to a hot electron phenomenon of a using TR nor the increment of the number of photoetching processes PEP. CONSTITUTION:The external power supply voltage VCC is impressed to a drain, and at the same time the internal power supply voltage VCC'(+3V, etc.) generated from the source of an n channel enhancement type TRN9 having the gate and the drain connected to each other is impressed as the power supply of a p cannel load TRP1. Therefore the voltage VCC' having a lower potential than the VCC is impressed to high voltage VP in a write mode. Thus the hot electron is suppressed and therefore an LDD structure is not especially needed. This eliminates the use of PEP required for the LDD structure. Therefore the TR size can be reduced without deteriorating the performance owing to the hot electron phenomenon of the TR nor increasing the number of processes PEP.
