Title: Formation of thin silicon film
Inventor: NAKAJIMA KAZUHIRO
IPC: C23C16/24
Filed: 1993-06-24
Abstract: PURPOSE:To form a thin silicon film with high accuracy in the thickness and concentration thereof by subjecting a substrate to a process for rendering the main surface thereof semiconductive or metallic and terminating the main surface with a hydrogen atom, heating the substrate, and feeding a specified source gas containing silicon atoms to the main surface of the substrate. CONSTITUTION:A substrate 1 having semiconductive or metallic main surface is immersed into hydrofluoric solution to bond a hydrogen atom 2 to the terminal on the main surface of the substrate 1. The substrate 1 is then placed in the chamber of a filming equipment and heated while feeding a carrier gas. When dimethylsilane is admixed to the carrier gas and fed into the chamber, the terminal hydrogen atom 2 on the main surface of the substrate 1 reacts on the methyl group 3 of dimethysilane 5 to produce methane 4 and silicon atoms deposit on the main surface of the substrate 1. Furthermore, the hydrogen atom in dimethysilane 5 is bonded to the terminal of the substrate 1 as a terminal hydrogen atom 2. Since the dimethylsilane gas is fed to the substrate 1, a thin silicon film is formed.

The mixture is charged into a form 11 by a placing machine 10, cured, and then solidified. The cured and solidified concrete is then released from the form 11. The concrete can be easily released, because the cement 3 is sufficiently expanded before being placed in the form 11 and hardly expanded and contracted in the curing in the form 11.

Title: Digitally controlled variable signal attenuator
Inventor: KOGA YASUHIRO
IPC: H03H7/25
Filed: 1986-06-30
Abstract: PURPOSE:To attain high resolution even with a wide signal attenuation range by providing a reference voltage generator generating a reference voltage which decides the analog converting quantity per bit for a D/A converter, and varying the reference voltage based on the control voltage. CONSTITUTION:A reference voltage generator 7 is provided and its output reference voltage is varied according to an analog voltage fed to a PIN diode signal attenuator 1. Since the reference voltage from the reference voltage generator 7 is changed by a control voltage (analog voltage) fed to the PIN diode signal attenuator 1, the analog output change quantity per bit in an A/D converter 2 is varied. Then the analog variable quantity has to be made variable. That is, with a small slope in the signal attenuation quantity versus control voltage curve, the analog output change quantity per bit is increased, and with a large slope, conversely, the analog output change quantity per bit is decreased.

Filed: 1990-06-14
Abstract: PURPOSE:To prevent loss of coverage of barrier metal by forming HF resistant substance on the uppermost layer of an insulting film in a method of manufacturing a semiconductor device including a step of forming an electrode structure of polysilicon/barrier metal/electrode metal. CONSTITUTION:When an Si02 film generated by oxidizing the surface of polysilicon 7 is removed with HF, Si3N4 5 is not side etched. Thus, when barrier metal TiN 8 is sputtered, the metal 8 is not cut by the pattern edge of the polysilicon 7. Accordingly, when Al 9 is then sputtered, the Al 9 is completely separated from the polysilicon 7 by the TiN 8. When it is patterned, an emitter electrode of a bipolar transistor having an electrode structure of polysilicon/ barrier metal/electrode metal can be formed.

Title: Fuel steam detecting device for internal combustion engine
Inventor: MORIWAKI HIDEO
IPC: F02D41/02
Filed: 1991-05-29
Abstract: PURPOSE:To improve precision of detection of a fuel steam component in fuel- air mixture fed from the canister of a fuel steam exhaust suppressing device to an engine intake air system. CONSTITUTION:A hot-wire type flow meter 18 is mounted on the bottom part chamber 153 of a closed bottom type canister 15. A flow rate of air-fuel mixture of air and fuel steam flow through a purge pipe 17 is calculated based on detected values from a throttle opening sensor 4 and a sensor 10 for an absolute pressure in an intake air pipe. A fuel steam flow rate (a component) is calculated based on the flow rate and the output value of the hot-wire type flow meter 18. Since the velocity of flow of air-fuel mixture in a bottom part chamber 153 is low, measurement of a flow rate is effected at a low velocity of flow by means of the flow meter 18.

Title: Background noise eliminating device
Inventor: TAKADA SHINSUKE
IPC: G10L25/78
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To improve the acoustic feeling and the tone quality by detecting narrow bandwidth noises and switching the noise eliminating characteristics. SOLUTION: An adder 28 performs the noise eliminating process in which estimated background noise signals are subtracted from output signals X(f) of an FFT computing element 4 and processed signals E4(f) are transmitted to a narrow bandwidth noise discriminating section 29. A frequency axis voice detector 31 provides a maximum power level at a signal X(f) and its frequency to the section 29. Then, the section 29 obtains the signal value at the maximum power level frequency for a K-th frame and then, obtains the deviation between the maximum power level and the obtained value. If the deviation is larger than a threshold value, the section 29 discriminates that they are background noises having narrow bandwidth noises ('there exist narrow bandwidth noises'). If the deviation is less than the threshold value, it is discriminated as voices.  Then, the noise eliminating characteristics in the output signals from the device are varied in accordance with the discrimination result of the section 29.
