IPC: H01L21/304
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To obtain a surface treatment method which prevents the surface of a semiconductor substrate from being roughened so as to obtain a smooth surface by a method wherein the semiconductor substrate on which a spontaneous oxide film is formed is heated in a rare-gas atmosphere containing O2 gas, an oxide film is formed newly separately from the spontaneous oxide film and the oxide film is heated in an H2 gas atmosphere so as to be removed wholly. SOLUTION: A semiconductor substrate W in which a spontaneous oxide film ON is formed on the surface is heated in an Ar gas atmosphere containing O2 gas while a temperature inside a process tube is heated and held in a prescribed temperature range for a prescribed time. Then, the spontaneous oxide film ON is homogenized, a homogeneous oxide film ON is generated newly, and an oxide film O which is homogeneous as a whole and whose thickness is 2 to 15Å is formed. In addition, the oxide film is heated in an H2 gas atmosphere or in a rare-gas atmosphere containing H2 gas, and the oxide film O is removed wholly. Thereby, it is possible to prevent the surface of the semiconductor substrate W from being roughened, and a smooth surface can be obtained.

Title: Remote-controlled transmitter and pre-program key setting method
Inventor: MURAOKA SHIZU
IPC: H04Q9/00
Filed: 1993-09-24
Abstract: PURPOSE:To improve the operability of a remote controller by allowing a function revision means to revise correspondence to a storage means. CONSTITUTION:When a power key is depressed, a control circuit 3 of a remote- controlled transmitter 1 detects the depression of the power key and an ID of a control signal corresponding to the power key is acquired from a fixed table in a ROM 4 and a format of a corresponding control signal is acquired from a control signal table of the ROM 4. A transmission circuit 6 commands the lighting of an infrared ray based on the format. The circuit 6 lights an infrared ray emission diode 61 based on a command from the control circuit 3. A monitor setting the allocation of a function to a pre-program key of the transmitter 1 receives an infrared ray from the transmitter 1 and detects a control signal from the infrared ray and displays a function of a TV to be commanded in characters. Thus, the function of an equipment to be controlled by remote control is selected by the user and the user selects and sets the arrangement of allocated operation keys, then the operability of the remote- controlled transmitter is improved.

IPC: E02D3/12
Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To shorten the period of time for repairing and to simplify it by burying steel pipes furnished with check valves, water stop plates, etc. with specified intervals at the time of depositing batholith concrete and injecting a grout material through the steel pipes in the case when a void is produced below a batholith. SOLUTION: Short pipes 5 of vinyl chloride pipes, etc., are buried with specified intervals (for example, 5m pitch) at the time of laying macadams 7 on a pile foundation and depositing conditioning concrete 8 on them. Batholith concrete 9 is deposited after erecting a steel pipe 1 furnished with a water expansible water stop material 3, a water stop plate 4 serving both as an anchor, a check valve 2, etc., on these short pipes and arranging normal reinforcement. Thereafter, drilling of a grout injection hole at the time of repairing is eliminated by injecting a grout material by removing a plug 10 and connecting an injection pipe in the case when a void is produced between a concrete structure and a peripheral ground below the concrete structure after a long period of time passes, support force is lowered and repairing is required.  Consequently, it is possible to inject grout easily even when a working surface is narrow.

Title: Apparatus and method for processing signal of resolver
Inventor: OYA EIJI
IPC: G01D5/245
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To output a more accurate angle unaffected by noises. SOLUTION: Two-phase signals from a resolver are sampled twice in succession across a peak. The sum of squares of the value sampled first is obtained to determine whether it is within a predetermined range from a predetermined value Sset. When the value sampled is affected by noises, i.e., when noises are superimposed thereon, the sum of squares is not within the predetermined range and an angle is therefore derived from the value sampled later. As a result, a more accurate angle unaffected by noises can be output.
