Title: Ignition detecting device for combustor
Inventor: MAKINO TSUTOMU
IPC: F23N5/08
Filed: 1990-01-12
Abstract: PURPOSE:To make it possible to perform ignition detection at the time when a combus tor shifts to stable combustion accurately and effectively by a method wherein ignition is detected by a flame sensor when flame has gone approximately around the periphery once. CONSTITUTION:At a position which is in a range of 180 deg. to 330 deg. with respect to advance in the circumferential direction of flame F which is generated by an igniting element 6, and where the light of the flame F can be received, a flame sensor 11 is arranged. For this reason, the flame F is not detected at 180 deg. or lower, however, a range which is not more than 180 deg. corresponds to a first stage, which is for forming of a seed of flame, and a second stage, which is on the way of growing of the seed of flame, and these ranges in which there is a possibility for quenching of the frame F are not detected as ignition, and therefore, erroneous detection for the quenching zone of the flame F can be avoided. In the meantime, the flame F is not detected at 330 deg. or higher, however, this is because there is a possibility that the red heat of the igniting element 6 or residual seed of flame may be detected as the flame F at 330 deg. or higher even when the flame F has been quenched. Since these ranges are not detected as ignition, erroneous detection for quenching of the flame F can be avoided. By this method, the only flame at the time when a combustor shifts to stable combustion is accurately detected as ignition.

Title: Pure water bubbler
Inventor: MAKITA HIROYUKI
IPC: G05D9/00
Filed: 1982-01-18
Abstract: PURPOSE:To produce wet gas continuously on the same conditions for a long period by detecting the amount of pure water in a bubbler container through a liquid level sensor and holding the amount of pure water in a bubbler constant all the time. CONSTITUTION:While a solenoid valve 28 is closed, the amount of pure water 27 decreases as wet gas is produced, and at the same time, the liquid level in a liquid level monitor pipe 26 is lowered. Once the liquid level sensor 25 detects that, the solenoid valve 28 is opened to supplement pure water through a pure water supply intake 27 and the pure water increases in amount to elevate the liquid level. When the liquid level rises above a specific water level, the liquid level sensor 25 detects that again and then the solenoid valve 28 is closed. Said operation is repeated to hold the amount of pure water 15 constant within a specific range, thus producing the wet gas having the same density continuously for a long period.

IPC: H04N19/139
Filed: 1995-01-18
Abstract: PURPOSE: To detect the moving object of a small area with accuracy by detecting a true motion vector based on an initial deviation vector and the image signals of a present field and a previous field. CONSTITUTION: In an initial displacement vector selection circuit 42, an accurate initial deviation vector C is selected and outputted without increasing the candidates of the initial deviation vector. In a vector detection circuit 50, a present filed signal 1 and a previous field signal 2 are inputted via input terminals 10 and 12, and the signals are supplied to the circuit 42, the vector detection circuit 50 and a vector evaluation part 60.

The evaluation part 60 outputs only the motion vector that the value of the motion vector is in a prescribed error range from an output terminal 14. The same evaluation is performed for the signals 1 and 2, the output of an accumulation circuit is compared with threshold and the excellent one is defined as a true motion vector.

Title: Automatic focusing camera
Inventor: TSUJINO KAZUHIRO
IPC: G02B7/28
Filed: 1991-01-22
Abstract: PURPOSE:To stabilize the focusing operation of an object being low contrast by reducing offset voltage equivalent to an A/D conversion output at the time of light-shielding from the DC bias of an input signal for an A/D converter at the time of regular photographing before the focusing operation. CONSTITUTION:A microcomputer 50 sets a focusing mechanism 60 in a close state before the start of the focusing operation, sets a focus evaluation value obtained from an evaluation value generation circuit 45 as an offset value, converts it into PWM and outputs it to an offset voltage generation circuit 40. The circuit 40 amplitude-detects 41 a PWM output, converts it into DC voltage, adjusts 43 a prescribed gain and holds 44 it as offset voltage. At the time of regular photographing, offset voltage is inputted to a subtracter 22, offset voltage is subtracted from the DC bias which is set through a resistance 21 in an input signal for the A/D converter 5e and it is inputted to the circuit 45. Thus, the DC offset voltage error of the A/D converter 5e is removed from the obtained focus evaluation value and the stable focusing operation is realized.

Title: Method and plant for production of gaseous mixture containing carrier gas, oxidative gas and silane
Inventor: VILLERMET ALAIN
IPC: B01F23/10
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To safely obtain a specified final gaseous mixture comprising a carrier gas, an oxidative gas and a gaseous mixture of a neutral gas and a silane gas having the silane content less than the self-ignition limit of silane in air, by controlling the final gaseous mixture under dynamic conditions. SOLUTION: In the example of a mixing zone 15 under dynamic conditions, the mixing process is carried out among a silane/neutral gas primary mixture sent through a pipe 18 to the mixing zone 15, an oxidative gas (e.g. oxygen) sent through a pipe 17 to the zone 15, and a gas flow containing a carrier gas from a pipe 16 to the zone 15. The primary mixture has the silane content lower than the self-ignition limit of silane in air. In this process, the silane (from the pipe 18) and the oxidative gas (through the pipe 17) do not cause stagnation in the pipe 16 but are immediately carried by the strong carrier gas flow through the pipe 16. If the silane gas and oxidative gas stagnate, production of silica particles between these gases is accelerated.

Abstract: PURPOSE:To make a dimensional change absorbable in a bearing even if a bearing inner diametral part receives a thermal change as well as to keep the bearing inner diameter constant even under any temperature conditions, by cutting down a ring bearing groovedly or partially in the longitudinal direction. CONSTITUTION:When an accelerator is operated, an accelerator wire 10 is pulled in the arrow direction, a lever B7 moves counterclockwise, and a lever A5 moves counterclockwise via a lever C8. Since the lever A5 and a throttle valve 3 are tightly attached to each other, this throttle valve 3 is opened or closed as far as a portion proportional to accelerator pedal reserve. And, the lever B7 is supported on a shaft 6 by a ring bearing 13 whose inner diameter notched at one end as shown in (a)-(d) is formed into cylindrical form. A thermal expansion variation of this ring bearing 13 is able to reduce a clearance with the shaft 6, so that variations in motion of a link 7 due to play are sharply reducible.

Filed: 1995-01-19
Abstract: PURPOSE: To prevent such a case where a controlled object is controlled after a wrong control parameter is set by fixing the characteristic of the controlled object by a step response method and deciding whether the dead time and the largest inclination are correctly identified. CONSTITUTION: An identification means 5 of a controller 1 successively calculates the dead time Ln and the inclination Rn corresponding to the change of the controlled variable in the prescribed sampling synchronization and identifies the dead time L and the largest inclination R based on the change of controlled variable detected by a step response method after a step manipulated variable of 100% is outputted from a step manipulated variable output means 3. An identification result decision means 9 decides whether the time L and the inclination R are correctly identified by the means 5. The correct identification is decided when the product (L * R) of the time L and the inclination R identified by the means 5 is included in a prescribed range (L * Rmin to L * Rmax ). Then no correct identification is decided if the product (L * R) is excluded out of the preceding range.
