Title: Processing device
Inventor: ROHATA TSUTOMU
IPC: H01L21/205
Filed: 1992-12-18
Abstract: PURPOSE:To prevent dew condensation on the external wall surface of a processing room even when the wall of the processing room is sufficiently cooled. CONSTITUTION:The wall part of a processing room 2 employs a double-wall configuration, and a coolant passage 12 through which coolant 13 flaws is farmed at an inside wall part 11, and a space part 15 is formed between the inside wall part 11 and an outside wall part 14, and through the space part 15, such inert gas 16 as argon flows. With this, even when the inner wall surface of the processing room 2 is sufficiently cooled, since the space part 15 works as a heat insulator, dew condensation on the outer wall surface of the processing room 2 is suppressed. Therefore, without allowing dew condensation on the outer wall surface of the processing room, the inner wall surface of the processing room 2 can be sufficiently cooled and generation of CVD film on the inner wall surface of the processing room can be reduced. Since, due to the inert gas 16 filled in the space part 15, intrusion of atmosphere is prevented, dew condensation in the space part 15 is prevented.

Title: Inverter circuit
Inventor: ITO HIROYUKI
IPC: H05B41/24
Filed: 1992-12-25
Abstract: PURPOSE:To suppress an overcurrent by stopping the pulse output for a fixed period after the overcurrent is detected, and limiting the pulse output width in response to the magnitude of the current level. CONSTITUTION:The full-wave rectified voltage of a rectifier circuit 1 is fed to a transformer TS.4 according to the switching action of a transistor TR1 by the output pulse C of a switching drive circuit 3, and it is outputted to an output terminal O after impedance conversion. When the transistor TR1 is set to the on-state, the voltage extracted by a resistor R1 is integrated by an integrating circuit 6. If this integrated value exceeds the threshold value, a transistor TR2 is turned on, RSF/F 8 is set, and the pulse output control signal D of the H-level is outputted from an output terminal Q to the switching drive circuit 3. The switching drive circuit 3 stops the output of the pulse signal C, and the transistor TR1 is set to the off-state to stop the output. The output of the pulse signal C is stopped to stop the power output for the time length set by a timer section 9. An overcurrent is limited and suppressed by a series of actions.

Title: Heating cooker
Inventor: TSUKADA SATORU
IPC: A47J37/08
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To eliminate a long time conduction waiting state even if a cooking start waiting state is missed to be released while avoiding useless power consumption. SOLUTION: A cooking start waiting state is released when a specified time is measured by clock means 21 after operating an auto-key 3 or ending the cooking operation so long as any other operation is effected. Consequently, cooking operation where a heater 15 is conducted is not started even if a start key 4 is operated later. Furthermore, useless power consumption can be avoided because the display of cooking start waiting state is not sustained on a display means 12.

Title: Engine cylinder pressure detection device
Inventor: ABE KENJI
IPC: G01M15/04
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To enable appropriate engine control at all times by calculating the differential pressure between the cylinder pressure at a predetermined crank angle range when taking the pressure value such that the pressure inside the cylinder is near atmospheric pressure, and absolute pressure within the intake manifold, performing the atmospheric pressure correction on the detected cylinder pressure by only the differential pressure, and attaining the final cylinder pressure detection value. SOLUTION: A CPU 31 of an ECU 5 reads the outputs from an intake manifold pressure sensor 3, cylinder pressure sensor 6, crank angle sensor 38, circulating water temperature sensor 42 and the like. The outputs from the sensors are then stored in a RAM 33 and a signal is generated that controls injectors 4 and an ignition system 41 and the like according to those outputs. Also, when the CPU 31 uses the cylinder pressure for engine control, it first reads the crank angle output from a counter 37 and determines whether the crank angle is within the predetermined angle range.  When it is determined that the crank angle is not within the predetermined angle range, the differential pressure between the cylinder pressure and intake manifold pressure at that time is calculated, the cylinder pressure is corrected by that differential pressure, and the final cylinder pressure detection value is attained. This helps appropriate engine control.

CONSTITUTION:Steel pipe columns 11 at the top of which a covering plate 12 is fixed is erected at a specified position, concrete 16 is filled into the steel pipe columns 11, and a pressure-resistance cover 17 is installed on the covering plate 12 to form a closed clearance over the upper surface 16a of the concrete. A pressure-fluid is fed into the clearance to pressurize the upper surface 16a of the uncured concrete and give a tensile force to the steel pipe column 11. In this way, the concrete 16 is cured under the tensile force. After it is cured, the tensile force is removed, the pressure-resistant cover 17 is removed, and concrete is filled into the clearance between the upper surface 16a of the cured concrete and the lower surface 12c of the covering plate. Thus a prestress can be introduced into the infilled concrete steel pipe columns during the construction of a building, and the advantages of the infilled concrete steel pipe columns can be displayed fully.
