IPC: F23D11/44
Filed: 1979-03-08
Abstract: PURPOSE: To provide a stable combustion condition even if the combustion volume is made to be variable by a method wherein a partition wall having a through-hole at its center is arranged at the lower part of the burner top and a porous plate having holes with a smaller diameter than a thickness of the plate is positioned.  
     CONSTITUTION: Partition plates 6" and 6' having through-holes 5 at their centers are arranged at the lower part of the burner top 3 and at the upper part of the burner main body 1, a porous plate 7 with holes having smaller diameter than a thickness of the plate is positioned at the through-port 5, a helical cylinder 8 is suspended down from the through-port 5 of the lower partition plate 6', the lower end of the helical cylinder is made such that its air supply port is lower than the other portions. The fuel fed together with the air from the pipe 10 of the cylinder 9 is changed to a vaporized gas by the burner main body etc. heated by the evaporation heater 2 and then ignited to be injected from the flame port 5. As the combustion proceeds, thermal cracking from the vaporized gas to combustion gas is performed only on the upper surface of the porous plate 7, so that a condition variation of the gas to the combustion gas is performed at substantially specified position and a stable combustion condition may be maintained even if the combustion volume is changed.

Title: Adaptive controller
Inventor: FUJIWARA TOSHIKATSU
IPC: G05B13/04
Filed: 1989-02-06
Abstract: PURPOSE:To stabilize control, to improve controllability so as to speedily follow the characteristic change of a controlled system by installing a sampling device, an ARMA model estimation device, a time shift device for ARMA model and a manipulated variable calculation device. CONSTITUTION:The sampling device 11 fetches a control deviation y(t) and a manipulated variable u(t) at every sampling time DELTAt. At that time, the time DELTAt becomes smaller than a time DELTAT by assuming DELTAt=DELTAT/k(conventional sampling time) ((k) is 2,3,4...). Next, the ARMA model estimation device 12 sets the new time DELTAT to be (k) times as much as the time DELTAt (DELTAT=kDELTAt), and it estimates the parameter of the model by a successive minimum square method and the like. A manipulated variable (u) which can set the distribution of the control deviation (y) of a kDELTAt time light to be minimum is calculated and outputted at every DELTAt time through the time shift device for ARMA model 13 and the manipulated variable calculation device 14. Thus, a prediction time width becomes large, control is stabilized and controllability, especially, performance for disturbance can be improved. Then, follow-up for the characteristic change of the controlled system can speedily be executed.

IPC: G02B26/12
Filed: 1989-02-08
Abstract: PURPOSE:To eliminate the curvature of field completely by providing two transparent parallel plates between a 1st image formation optical system and a rotary polygon mirror rotatably around axes at a different angle from the optical axis. CONSTITUTION:The two transparent parallel flat plates 8A and 8B are provided between the 1st image formation optical system 2 and rotary polygon mirror 3 rotatably around axes 9A and 9B at the different angle from the optical axis. Then the two parallel flat plates 8A and 8B are rotated in the opposite directions as a deflection scan is made. Therefore, an image formation position on a plane corresponding to the rotating direction of a light beam shifts according to the deflection scan to compensate the curvature of field caused by the deflection scanning. Consequently, the curvature of field in one scanning direction is corrected without causing a shift in optical axis nor affecting optical characteristics in any other scanning direction.

Filed: 1985-02-15
Abstract: PURPOSE:To prevent the generation of flection in a boring bar and promote the improvement of machining accuracy and machining efficiency, by swivelably suspending the boring bar to be rotated and driven about a vertical axial line and performing boring. CONSTITUTION:A boring bar 7, being swivelably formed in every direction, is suspended from a tool head 6. The boring bar is held by its dead weight in a perpendicular condition. Under this perpendicular condition, the boring bar, being slidably and rotatably supported and concentrically positioned with the hole of a work W, performs boring. In this way, the boring bar, whose dead weight acts in the direction of its axial line, is prevented from generating flection in the bar. Accordingly, the boring bar, enabling a rotary speed to be increased with no generation of vibration, improves also machining efficiency.

Abstract: PROBLEM TO BE SOLVED: To accelerate the mixing raw liquid and a flocculant simply and surely, to control the clogging of a filter cloth by sliding on the cloth, and to concentrate sludge stably and efficiently by installing a chemical injecting means for adding the flocculant into the raw liquid and a liquid receiving part which is installed in a rotary basket and receives the raw liquid. SOLUTION: During the high speed rotation of a rotary basket 4, raw liquid added with a flocculant from a chemical injecting means in a raw liquid supply pipe 7 is supplied temporarily to the liquid receiving part 12 in the bottom part of the basket 4. Since the liquid receiving part 12 is rotated at a high speed integrally with the basket 4, the raw liquid is agitated enough in the liquid receiving part 12, and the reaction between sludge and the flocculant (chemical) is accelerated. The raw liquid is supplied to be made to overflow the upper end of the liquid receiving part 12 by the centrifugal force of the basket 4 to collide with a filter cloth 5 and moved upward gradually on the surface of the filter cloth 5 to be filtered and thickened in a separation zone.  Namely, the raw liquid is separated efficiently into filtrate passing through the filter cloth 5 and a thickened liquid (sludge) caught by the filter cloth 5.
