Title: Latchup-proof semiconductor device
Inventor: KOIKE TERUMASA
IPC: G01R31/26
Filed: 1991-12-06
Abstract: PURPOSE:To eliminate effects of a latchup phenomenon on a CMOS semiconductor device under a radiation environment or a high electromagnetic field environment. CONSTITUTION:Optical waveguides 1, 2 and 4 which are composed of oxide films are formed in a CMOS IC. The direction of a light emitted by a latchup phenomenon is turned 90 degrees at the end part of the optical waveguide 4 and inputted to a photoelectric transducer 3. Transistors 5 and 22 are provided on the output side of the photoelectric transducer 3. The electromotive force of the photoelectric transducer 3 is applied to the depletion-type MOS transistor 5 to cut off a power supply current to dissolve the latchup phenomenon. Further, the non-volatile depletion-type MOS transistor 22 is provided in parallel with the depletion-type MOS transistor 5 and stors charge in its floating gate and isolates a semiconductor device from the power supply permanently. A latchup generation signal terminal 27 informs other devices of the generation of the latchup phenomenon.

Title: Optical analyzer and optical analysis method
Inventor: DONARUDO DABURIYUU SUTEINGU
IPC: G01N21/47
Filed: 1991-12-06
Abstract: PURPOSE: To enable accurate positioning by detecting encoded radiant energy by a sample which is adjacent to an ATR(attenuation total reflection) crystal body in observation mode and analyzing the sample in analytic mode by using the encoded radiant energy. CONSTITUTION: In the observation mode, the surface of the sample 26 can be observed through an observation port 13 along an optical path passing through a Cassegrain object and ATR crystal 22. In this case, the observation can selectively be made only by changing an incidence and an exit aperture which changes an incidence angle and a reflection or radiation angle without moving the sample 26. In the analytic mode, narrow-band radiant energy from a light source 3 is made incident on the sample 26 through the aperture of an incidence mask 18 and the crystal 22. Energy reflected or emitted by the crystal 22 is reflected by primary and secondary optical elements 21 and 20 and passes through the exit aperture of the mask 23, and the energy is encoded with the information of the sample 26 because of energy absorption by the sample 26 and made incident on a detector 25.

IPC: C21D9/00
Filed: 1987-12-21
Abstract: PURPOSE:To produce a track bushing which is hardened at a high depth and has excellent durability by subjecting the track bushing to oil hardening over the entire part, low-temp. tempering, induction tempering and high-frequency hardening of the bore party, and low-temp. tempering of the entire part, successively. CONSTITUTION:The entire part of the track bushing 1 is heated to about 800 deg.C and is oil- hardened in an oil tank 5; thereafter, the bushing is tempered at about 180 deg.C to form the hardened layer uniform from the surface of the outside diameter part down to the core part. The bushing is then subjected to the induction tempering by a moving coil 6 from the bottom to the bottom end of the bore part. The completely hardened and tempered layer is thereby formed from the bore part to the core part. The outside diameter part is cooled with a water cooling jacket 7 so that the prescribed cured layer remains in the outside diameter part at this time. The bore part is then subjected to the high-frequency hardening by the moving coil 6 and a water cooling jacket 8 for the bore part from the bottom to the top end. The outside diameter part is cooled at this time. The prescribed cured layer is thereby formed in the bore part and the residual stress is provided thereto. The entire part of the track bushing material 1 is thereafter charged into a tempering furnace 9 where the bushing is subjected to the low-temp. tempering at about 180 deg.C. The track bushing hardened at the high depth is thereby obtd.

Title: Cpu control circuit
Inventor: MIYAWAKI SEIJI
IPC: G06F11/30
Filed: 1989-12-14
Abstract: PURPOSE:To prevent a CPU from being shut-off in a ready signal waiting state by forcedly turning a NOT READY state to a READY state when the NOT READY state is continued for a prescribed time and then informing the change of the state to the CPU. CONSTITUTION:When the number of counted clocks of a clock signal CLK exceeds a previously set prescribed value, a counter circuit 4 outputs a counter signal A by deciding that the NOT READY state of the READY input of the CPU 2 is continued for a prescribed time and no device is allocated to an address accessed by the CPU 2 or the status change of a READY signal is not generated by any reason. The counter signal A is inputted to the READY input of the CPU 2 through an OR circuit 5 to forcedly switch the state of the READY input of the CPU to the READY state. Consequently, the CPU can be prevented from being held at a READY signal waiting state after continuing the NOT READY state and being shut-off in the READY state as it is.

IPC: G01N23/225
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To position a sample, taking the inner periphery of the doughnut-like sample as a reference, by fitting a partial cylindrical surface to the inner periphery of the doughnut-like sample to position the sample, and abutting the center hole contact surface of a movable member against the inner periphery of the doughnut-like sample. SOLUTION: A doughnut-like sample Sd is supported by a sample placing surface 4c of an upper sample support member 4. The diameter of a partial cylindrical surface 3i of a pair of projecting part 3h is fitted to the inner periphery of the sample Sd. Therefore, the sample Sd placed on the sample placing surface 4c is fixed by a center hole contact surface 14e of a movable member 12. The sample on the sample placing surface 4c is thus positioned by using the center hole of the sample Sd, so that a sample Sd larger than the outside diameter of the sample placing surface 4c is placed and positioned. Accordingly, a sample Sd with a large outside diameter can be observed and analyzed by use of the sample holder with a small outside diameter.

CONSTITUTION:When a hydraulic release valve 60 is used, in the time of upshift, an internal pressure (operating oil) in a pressure oil chamber in a rear stage clutch (upshift side clutch) acts on a port 124a in an upshift side formed in a housing 61 of this valve 60, and its spool 62 is moved to a release position. In this way, an oil pressure layer of a front stage clutch (engaging clutch before speed change) communicates with a drain port 125a, and this internal pressure is released. While in the time of downshift, the internal pressure in the pressure oil chamber in a rear stage clutch (downshift side clutch) acts on a downshift side port 122a, and moving the spool 62 of the valve 60 to the release position, similarly to the above, the pressure oil chamber of the front stage clutch communicates with the drain port 125a, releasing the internal pressure.
