Title: Mass energy spectrograph for charged particles
Inventor: HASHIMOTO KIYOSHI
IPC: G01N27/62
Filed: 1981-01-21
Abstract: PURPOSE:To increase the energy decomposing ability of a mass energy spectrograph by installing a charged particle detector at a convergent point of particle beams deflected by a magnetic field. CONSTITUTION:Incident beams 5 are parallel to each other, and the ratio of a deflection angle phid of the beam 5 to a magnet open angle OMEGA of the beam 5 is 2:1. A magnet plate is constituted so that the open angle of the magnet, which is measured by supposing a beam center 10 as an original point, becomes OMEGA when the beam 5 is perpendicularly incident upon the magnetic field. A charged- particle detector 8 is installed at the beam convergent point. As a result, the detection efficiency of a mass energy spectrograph becomes the highest, and the energy decomposing ability of the spectrograph is increased.

Title: Gas sensor
Inventor: FUKUDA TOKUYUKI
IPC: G01N27/12
Filed: 1987-01-14
Abstract: PURPOSE:To directly drive a heating element by a commercial power source, by employing a heating element 5 with a positive resistance temperature coefficient for an electric heater to heat a resistor for gas sensing. CONSTITUTION:A thermistor with a positive resistance temperature coefficient is connected as heating element 5 on an electric heater through a resistor 3 for gas sensing and an insulation layer 15. Electrodes 2 and 2 are provided at both ends of the resistor 3, and electrodes 4 and 4 at both ends of the heating element 5. A series circuit having a resistor 6 connected to the resistor 3 for gas sensing and the heat generating body 5 are connected to a commercial AC power source of voltage 100V. As the voltage of the AC power source 7 rises, the temperature of the heating element 5 should go up. But being a thermistor with a positive resistance temperature coefficient, the heating element 5 is suppressed in the power consumption with an increase in the resistance value and as a power source voltage lowers, conversely, the resistance value decreases to enhance the power consumption, which combine to keep the heating value of the heating element 5 constant. Even when ambient temperature such as room temperature changes, the resistance value of the heating element 5 is varied to adjust the power consumption thereby maintaining the temperature of the heat generating body 5 at a constant level.

Title: Circuit for compensating recovery time of computer system
Inventor: TSUDA HIROSHI
IPC: G06F13/42
Filed: 1989-01-13
Abstract: PURPOSE:To prevent access speed from being decreased less than a required level by extending recovery time only when continuous access within prescribed time is performed on I/O devices with the same addresses. CONSTITUTION:When an I/O command S1 is outputted from a CPU 1, a latch circuit 4 latches an address with the leading edge of the output. Simultaneously, the output S3 of a pulse generator 7 goes to 'H' only for the prescribed time, and it is inputted to an AND gate 6. Next, the address sent from the CPU 1 is compared with a preceding address latched with the circuit 4 at a coincidence circuit 5, and a comparison signal S2 is inputted to the gate 6. The output of the gate 6 goes to (L) regardless of the output of the generator 7 when the result of the circuit 5 shows noncoincidence, and it goes to (H) only for the pulse output time of the generator 7 when coincidence is obtained. In such a way, the fall of a command is prohibited only when the continuous access within the prescribed time is performed on the I/O devices with the same addresses, thereby, the recovery time can be extended. Consequently, the access speed can be prevented from dropping below the required level.
