Title: Ashing
Inventor: SAKIYAMA TSUGIO
IPC: H01L21/306
Filed: 1987-05-25
Abstract: PURPOSE:To remove a resist film over the whole region of a semiconductor wafer within the same time by treating its ashing, thereby making relatively a greater amount of ashing gases irradiate a part which is datermined in advance out of regions of a substrate to be treated by irradiating the ashing gases. CONSTITUTION:The flow rate of an oxygen gas containing ozone which is supplied by an oxygen supplying source 28 and an ozone apparatus 29 is adjusted by a gas discharge regulator 25 and its gas is irradiated from a gas outflow part 20 to a semiconductor wafer 12. Simultaneously with the above irradiation, its gas is irradiated from a gas outflow nozzle 22 to an orientation flat part 21 of the wafer 12 through a gas feeding pipe 27 by a gas discharge regulator 26. And an exhaust volume of an exhauster 31 is adjusted and its exhaust is performed so that gaseous pressure nearby an ashing plane of the simiconductor wafer in a treatment chamber 11 will be, for example, in a range of about 700-200 Torr. In such a case, two gas outflows where one of them flows from an outflow hole 18 of a diffusing plate 19 to surroundings of the wafer 12 and the other one flows from the nozzle 22 to the orientation flat part 21 of the wafer 12 are formed between the gas outflow part 20 and the wafer 12.

Title: Freezing preventive device for hot water heater
Inventor: YAGYU TOSHIKATSU
IPC: F24D3/00
Filed: 1990-05-16
Abstract: PURPOSE:To change control operation of freezing preventive operation according to combustion operation of a burner during freezing preventive operation by discriminating normal combustion and safety operation and changing a water setting value which halts freezing preventive operation during normal combustion and safety operation. CONSTITUTION:Freezing preventive combustion of a burner 2 is checked based on the presence of an ignition signal input from a flame rod 16. When normal combustion is discriminated, the circulation of heat exchanger water by a pump 3 and small combustion are jointly used. On the other hand, when an ignition failure of the burner 2 is discriminated, a required safety action of the burner 2 is immediately taken so that the pump 3 may be driven singly. However, at this occasion, a water temperature setting value which forces freezing preventive operation to come to a halt, is changed and set to 10 deg.C. As a result, the heat exchanger water rises by fluid friction accompanied by forced circulation and heat input from an auxiliary heater 18 so that the water may arrive at the setting temperature in a short time, thereby eliminating such corners that the operation of the pump 3 alone may be continued for long time.

Inventor: AONO TADASUMI
IPC: F28F1/32
Filed: 1979-10-03
Abstract: PURPOSE: To improve cooling efficiency in case the direct cooling with a cooling fluid is difficult by a method wherein a cooling drum having flexible fins on the outer peripheral wall is inserted into the inside of a drum type body to be cooled and the point of a fin is made to contact with the surface to be cooled.  
     CONSTITUTION: On the outer peripheral face of a cooling drum consisting of an inner drum 1 and an outer drum 2, flexible fins 3 each of which has a longer diameter than that of an inner diameter of a pipe 4 to be cooled by δ are installed in multi-stages in a radiant state to the radius durection. This cooling drum is inserted into the inside of the pipe 4 to be cooled and a cooling material is made to flow between the inner drum 1 and the outer drum 2. With this, contact between the surface to be cooled and the fin approaches a favorable state because of flexibility of a fin itself, thus, resulting in a high heat transfer rate, as a result, even when direct cooling with a cooling fluid is difficult, cooling efficiency is improved.

Filed: 1985-06-14
Abstract: PURPOSE:To improve the electric reliability of an IC unit by using a conductive layer formed of a lower layer of Si-containing aluminum film and an upper layer of Cu-containing aluminum film. CONSTITUTION:When a peripheral circuit of DRAM and CMISFET is formed, Si is contained in an aluminum wiring film to control solid solution to prevent an aluminum spike, and Cu and Si are further contained to reduce a migration occurred by a high current density due to microminiaturization of wirings. However, when Cu- and Si-connecting aluminum is connected with a P-type layer is a CMISFET, a connecting resistance is abnormally increased. Thus, a multilayer wiring structure using an insulating film and a connecting hole is utilized, Si-containing aluminum is used for a lower layer, Cu- or Cu- and Si-containing aluminum is used for an upper layer, and wired as prescribed. Then, even if a P<+> type layer 30 of the CMISFET and aluminum wirings (lower layer) 18 are connected, a connecting resistance value cannot be reduced to accelerate the operation of an IC.

Filed: 1982-07-24
Abstract: PURPOSE:To enable to distinguish between the recovery from a power interruption or initial energization of a power source by recognizing the rotating state of a motor through a speed signal generator by a microprocessor. CONSTITUTION:A power interruption detector 7 detects the voltage drop of an AC power source 1, and outputs a reset signal to stop the function of a microprocessor 5. When a power is interrupted during the operation of a motor 11, the rotating state of the motor is recognized by inputting a signal from a speed signal generator 12 to the microprocessor 5 when the power source voltage is supplied to the microprocessor 5 to release the reset by the recovery of the power source from the power interruption or the energization of the power source by utilizing the fact that the rotating speed gradually decreases but does not stop instantaneously when the power is interrupted during the operation of the motor 11. If during the rotation, it is judged as being the recovery from the power interruption, and if stopping, it is judged as being the normal energization of the power source. When judged as being power interruption, the process of power interruption is executed such as phase matching or the like.

Abstract: PURPOSE:To prevent malfunctions dependent upon shift of the fundamental frequency of the transmission side and the receiving side, by making it possible to correct the read pulse generation time by transmitting the same frame twice and adding a bit for read time correction to this frame, in the remote control device. CONSTITUTION:When the first bit of one frame of the frequency modulation wave dependent upon the fundamental frequency of the transmission side is received, counter correction pulse generating circuit 40 drives counter reset circuit 41 and resets counter 39. When counter 39 detects receiving of the bit for read time correction (the 5th bit) in one framebit divisional input signal detecting circuit 34 resets counter 39 partially by receiving of the second bit for read correction (the 6th bit) to synchronize read pulses applied to shift register 35 with the input signal again. By transmitting the same frame twice, agreement is checked in the receiving side. Consequently, read error of the receiving signal dependent upon shift of the fundamental frequency of transmission and receiving sides can be prevented.

This read out voltage is multipled and a large output signal is generated. If a switching element such as PLZT is provided on the light incident surface of the SIT, the removal of external light is easy. Always exact range finding is accomplished by a simple constitution using the plural SITs.
