Title: Combustion blast fan for burner
Inventor: KOBAYASHI SHIGEO
IPC: F23L1/00
Filed: 1985-02-08
Abstract: PURPOSE:To prevent defective combustion by providing at the upper section of a burner a blast which sends combustion blast into a burner and also a filter at the lower section of the blast fan and sending into the burner through a filter the suction blast that is sucked from a suction opening. CONSTITUTION:Combustion flames becomes a hot blast and the latter mixes with the outside air to produce a hot blast for drying. This hot blast is sucked by the exhaust fan 9 at the rear section of a dryer 6 and flows through across a drying chamber 11. Corn grains placed in the dryer 6 are dried while they are flowing down from a storage chamber 10 to the drying chamber 11. When their moisture reaches a specified value, the dryer 6 automatically stops. Since, during the drying operation, the combustion blasts are sucked from a suction opening 4 and the sucked combustion blasts go up to the upper section, most of dusts in the sucked combustion blasts drip before they go through a filter 3, which allows the filter 3 to be free from clogging by dusts. This condition in turn keeps the burner 1 burning almost in a stable state.

Inventor: OOMURA KAZUMICHI
IPC: H01L21/324
Filed: 1983-02-17
Abstract: PURPOSE:To obtain the semiconductor thin film of high quality by a method wherein in the process of fabricating the semiconductor crystal film on an insulating film, the insulating film is selectively formed on a single crystal semiconductor substrate at first and the whole surface including this film is coated with a film of low-melting metal including a semiconductor or an alloy film of a semiconductor and low-melting metal and then it is annealed to perform solid-phase epitaxial growth of the semiconductor over the whole surface. CONSTITUTION:An Si single crystal substrate 1 is subjected to heat treatment to produce an SiO2 film, a half of which divided by a straight border on the center of the substrate 1 is then removed by etching up to its end. Next, the surface of the substrate 1 is treated with the mixed solution of H2O and HF in the ratio 20:1 and is inserted into a vacuum chamber where the natural oxidation on the substrate 1 is removed. After that, the inside of chamber is made to be vacuum of 10<-8>Torr and the whole surface of the substrate 1 including a half of the film 2 is coated with an Sn-Si alloy film 3 including about 15% of Si using electron beam. Next, the substrate 1 is transferred into an electric oven flowing N2 gas and is heated up to 350 deg.C for about 100hr to perform the solid-phase epitaxial growth. Consequently, the single crystal thin film of high quality can be obtained over the whole surface.

Title: Gas mixer
Inventor: SUGIYAMA MASAYUKI
IPC: G05D11/02
Filed: 1988-02-05
Abstract: PURPOSE:To stabilize control for mixture of gas with a gas mixing device that secures a prescribed mixing ratio between the gas of one side and the gas of the other side by adding a valve to a supply line for the gas of the other side to perform the turn- down control if the flow rate of the gas of one side is less than a prescribed level. CONSTITUTION:A blower 24 is started and a delivery valve 25 is opened in steps based on the instruction of an interrupting circuit 32. Then, the rate of the flowing gas A is detected by a flow rate meter 25 and given to a flow rate arithmetic circuit 27 against the gas B. The circuit 27 multiplies the gas mixing ratio supplied from outside by the flow rate count value of the gas A for acquisition of the flow rate command value of the gas B. This command value is issued to a valve opening amount control circuit 28. The circuit 28 compares the actual flow rate of the gas B obtained via a flow rate mater 21 with the command value fed from the circuit 27 and transmits the valve opening amount control signal of a supply valve 22 that is proportional to the difference obtained from said comparison. An opening amount correcting circuit 29 controls the gain in accordance with the characteristics of the valve 22 and opens and closes the valve 22 based on the corrected valve opening amount. Thus the gas B is supplied at an accurate flow rate.

Inventor: UNO MOTOO
IPC: F15B9/09
Filed: 1986-02-07
Abstract: PURPOSE:To keep favorable positioning accuracy by providing a feedback circuit with means for adjusting gain of displacement feedback means, interlocking with gain of set point adjusting means. CONSTITUTION:A displacement feedback gain signal Cs, a displacement set point adjusting signal Cp, and a velocity feedback gain signal Cv are output from rigidity setting means 12 for setting positioning and rigidity of a driving mechanism.

Title: Pattern formation to disk-like recording medium, pattern forming device and disk-like recording medium
Inventor: BABA HARUNORI
IPC: G11B5/65
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To prevent the off-track during the operation by detecting the center of a disk substrate with the use of an electron beam and forming a pattern while making this detected center as the reference. SOLUTION: An intermediate substrate of a magnetic disk medium is fixed to a table of the electron beam device. Next, the table is moved so that an inner peripheral circle of the intermediate substrate comes to the scanning range of the electron beam, then the inner periphery of the intermediate substrate is scanned (plural times) by the electron beam. The reflected electron coming out at this time is detected by a photomultiplier to measure the position X1, Y1 of one point on the inner peripheral circle of the intermediate substrate. By moving the table similarly, the position X2, Y2 of some other one point and the position X3, Y3 of further different one point are measured. The position coordinate (Xin, Yin) of the center of the intermediate substrate is obtained by calculation from the positions of these three points on the same periphery.  After the center is detected, the electron beam is emitted so that the photoresist layer becomes the arrangement pattern for forming the unit minute recording part.

Title: Working electrode for spark machining
Inventor: HIRAMATSU KAZUHIKO
IPC: B23H1/04
Filed: 1980-02-28
Abstract: PURPOSE:To minimize deformation of machining face of a work even when a working electrode is slightly worn, by making a slant face on the electrode. CONSTITUTION:A slant face 5A with an angle of inclination equal to that of an inclined machining face 8 is made on the tip of a working electrode, so that deformation of the machining face 8 can be minimized so long as the said slant face 5A remains unworn at the tip even when part of the electrode is worn out 6. This is also true for a case where a work is moved at the time of machining. The type of the inclined working face, straight or curved, makes no difference. The slant face 5A may be made to any side in accordance with the machining conditions, though it is found on every side of a working electrode shown in the figure. Deformation of the machining face can accordingly be minimized, even when the working electrode is minutely worn.

The signal is demodulated to color difference signals B-Y, R-Y by SECOM demodulator 8, 9, then modulated by PAL modulators 10, 11. The wave to be modulated is inputted to terminals 14b, 14a directly and via an inverter 13. A modulation wave whose phase varies at every one H is added 15 with a wave to be modulated from the modulator 10, and thus a PAL system color burst signal is outputted.

Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of the alignment of a plasma torch, and to stably obtain the excellent machining accuracy in the high-speed machining. SOLUTION: Because a spherical-supported shaft 30 is relatively rotated to a bracket 29, the displacement of the axis of an end part 22a of a cable protective piece 22 is smaller than the displacement of the axis of a plasma torch 20, the bending in the vicinity of the end part 22a of the cable protective piece 22 is mitigated to suppress the projection of a bent part in the horizontal direction, and the effect of the cable protective piece 22 on the alignment accuracy of the plasma torch 20 is avoided even when the groove angle is large.
