Title: Liquid fuel combustion device
Inventor: KUMAZAWA KATSUYOSHI
IPC: F23D3/10
Filed: 1986-07-31
Abstract: PURPOSE:To restrain the generating amount of carbon monoxide even upon setting weak combustion, by a method wherein the diameter of the upper part of an inner flame tube, arranged concentrically with an outer flame tube and provided with a plurality of venting holes, is formed so as to be smaller than the diameter of the lower part of the same. CONSTITUTION:When the condition of weak combustion is set, combustible mixture is generated near the upper end of a wick 62, the temperature of the wick 62 is increased, the amount of receiving heat of a fire pan 60 is increased, the amount of heat radiation through a heat absorbing pipe 114 is increased and the wick 62 is kept in a temperature substantially equal to the temperature upon strong combustion. Unburnt gas is burnt while forming a secondary flame at the slightly upper position of a boundary between an lower inner flame tube 96 and an upper inside flame tube 97 by air which flows into venting holes 90, 103 while ascending through a combustion chamber 84. The diameter of the inner flame tube 97 is made smaller at this part, therefore, the secondary flame is burnt perfectly without contacting with the main body 92 of the inner flame tube. The diameter of the upper inner flame tube 97 is made so as to be 0.75-0.85 times of the diameter of the lower inner flame tube 96 and the ratio in the height direction of the tube is made 1:3 substantially, whereby the generation of poisonous gas upon weak combustion may be restrained and red flame upon strong combustion may be eliminated.

Title: Method and device for detecting foreign matter
Inventor: AKIYAMA NOBUYUKI
IPC: G03F1/84
Filed: 1981-11-10
Abstract: PURPOSE:To detect the presence or absence of foreign matter after setting of a reticle in an exposure optical path by retreating a filter and an exposure control means from the optical path when foreign matter is detected and using the light from the light source directly as illuminating light for detection of foreign matter. CONSTITUTION:Light of a mercury arc lamp 1 of a foreign matter detector irradiates the surface of a reticle 7 by passing through a condenser lens 2, a mirror 5 and a condenser lens 6. When foreign matter 11 exists on the surface of the reticle 7, the irradiating light falls onto the matter 11 and generates reflected and scattered light. Therefore, plural pieces of photoelectric detectors 16 are provided on the upper side of the reticle 7. The reflected and scattered light is detected by the detectors 16 and the electric signals corresponding to said light are compared with a set value, whereby the presence of absence of the foreign matter is detected. It is possible to detect the presence or absence of the stuck foreign matter after setting the reticle in the exposure optical path by keeping the photodetectors 16 retreated from the exposure optical path during exposure.

Afterwards, the switch means B1 and B2 are turned ON and latch means F1 and F2 latch the potentials of the data lines (d) and the inverse of (d), namely, the data of a selected memory cell MS. Then, output is executed based on these latch data. Even when the ATD erroneously outputs the clock pulse phi by noise during the output and the switch means B1 and B2 are turned OFF by the clock pulse phi, the data are continuously outputted by the latch means F1 and F2 without interruption. Thus, the data can be read at high speed.

Title: Member of high thermal impact resistance
Inventor: SHIMANUKI SHIZUKA
IPC: C21D7/02
Filed: 1980-12-22
Abstract: PURPOSE:To decrease the influence by thermal impact of members and improve reliability by yielding and applying the residal compressive stress of the absolute value larger than that of the tensile stress generated by thermal impact beforehand to the surfaces of members that receive thermal impact. CONSTITUTION:In, for example, a water absorption nozzle of an atomic reactor pressure vessel or the like as a member that receives thermal impact, it is at the inside surface corners 1 of the nozzle in terms of stress concentration where thermal impact is of problem. Thereupon, the outside surface corners 2 opposite to the corners 1 are heated by using heating elements 3 such as high frequency heaters to give a temp. difference between both. The corners 2 are compressively yielded and the corners 1 are tensilely yielded by the thermal stress generated by said temp. difference. Then, when the entire part restores room temp. the corners 2 cause tensile yielding and the corners 1 compressive yielding, thus the absorption nozzle which is superior against thermal impact is obtained.
