Patent JP-H037803-A (JP)
Title: Burner
Inventor: MORIGAMI KAZUHISA
IPC: F23D11/10
Filed: 1989-06-02
Abstract: PURPOSE:To suppress the generation of CO during weak combustion and stabilize the secondary flames by providing a heat shielding plate that covers the vertical wall section of a cover on the upper face of the flange section at the upper end of the walls of a combustion chamber with a cooling gap between the vertical wall section and the heat shielding plate and positioning the heat shielding plate on the outside of the combustion chamber walls so as to form a stepped section at the upper section of the combustion chamber, and at the same time providing many through-holes in the heat shielding plate to supply secondary air to the upper section of the combustion chamber. CONSTITUTION:Secondary flames 10A', 10A'' radiate considerable radiation heat towards the side of a cover 17. The vertical wall section 17b of the cover 17 which does not receive cooling and heat shielding effects of secondary air that is jetted out of a secondary air hole 18 is shielded from the radiation heat by the heat shielding section 2a of a heat shielding plate 20, and, furthermore, it is cooled by part of the secondary air that flows as the arrow mark in the figure through a cooling gap 22 formed between the vertical wall section 17 and the heat shielding section 20a so that the section 17 is maintained at relatively low temperature, and almost no thermal deformation develops in it. Even if the vertical wall section 17b and the heat shielding section 20a develop thermal deformation a little, the secondary air flow that has a large influence on the combustion during weak combustion is supplied through through-holes 23 formed in the heat shielding section 20a. Consequently the air flow makes no change and the supply of secondary air conitinues as designed and it is possible to suppress the generation of CO.

Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To regulate the conditions for extracting desirable ion by another means different from a means for magnetic field regulation, and to selectively and efficiently extract the desirable ions. SOLUTION: This ion source is provided with an insulator 44 for insulating electrically a space between a plasma chamber container 4 and a plasma electrode (the utmost plasma side electrode) 21, and a direct current source 46 for impressing a direct current voltage VB between the container 4 and the electrode 21. In this constitution, ion energy E, coming from plasma into a space distributed with a magnetic field in the vicinity of a surface of the utmost plasma side electrode 21, is expressed by an expression E=VP±VB, where the VP represents a plasma potential for the plasma chamber container 4, and the VB represents the direct current voltage impressed from the direct current source 46.  The direct current voltage VB comes to +VB, when the voltage VB is impressed to make the utmost plasma side electrode side negative, and the voltage VB comes to -VB when impressed positively. Therefore the ion energy E is regulated by the regulating largeness and direction (polarity) of the voltage VB.

Abstract: PURPOSE:To constitute an extremely small-sized, inexpensive sensor and to control correctly the rotation of a motor by controlling the motor speed with the signal of the sensor which detects the rotating speed by using reflected light from a plane mirror of a rotary polygon mirror. CONSTITUTION:The rotating speed detection sensor 10 consisting of a light emission part 11 and a photodetection part 12 is fixed to the flange 4B of the motor 4 which drives the rotary polygon mirror 3. Light from the light emission part 11 when illuminating a plane mirror 3E is reflected and photodetected by the photodetection part 12, but deviates from the photodetection part 2 as the polygon mirror 3 further rotates. For the purpose, a switching element such as a phototransistor is used as the sensor 10, and then pulses are outputted extremely precisely according to the rotation of the polygon mirror 3. Consequently, the motor rotation is controlled correctly under PLL control, etc. Further, a code plate, etc., such as a photoencoder are not used, so the small-sized, inexpensive sensor is constituted.
