IPC: C23F1/00
Filed: 1995-03-30
Abstract: PURPOSE: To completely remove foreign matter and to decrease the exchange frequencies of tacky adhesive rolls by using the tacky adhesive rolls which come into contact with the surfaces of a metallic blank perpendicularly to a transporting direction and move to the outer side on at least the rear surface side at the end side parts at the time of removing the foreign matter sticking to the surfaces in the both end side parts of the metallic blank to be etched under transformation for the purpose of exposure after formation of resist films. CONSTITUTION: While the tacky adhesive rolls 2 placed in the side end parts of the metallic blank 1 are brought into contact with the surfaces of the metallic blank, the rolls are horizontally moved toward a right or left outer direction A with respect to the transporting direction. The horizontal movement of the tacky adhesive rolls 2 is executed by a step motor 2. The surface parts of the tacky adhesive rolls 2 in contact with the regions in the plate end parts are gradually changed by the movement and are brought particularly into contact with the plate ends having much foreign matter. The parts of the tacky adhesive rolls contaminated in the surfaces and degraded in tacky adhesiveness are extruded outward of the metallic blank 1.  Then, the regions in the plate end parts of the metallic blank 1 under transportation are eventually and successively brought into contact with the roll parts having always the good tacky adhesiveness and the complete removal of the foreign matter is made possible.

Title: Liquid fuel combustion device
Inventor: OKADA HIDEO
IPC: F23N3/02
Filed: 1986-04-01
Abstract: PURPOSE:To provide an excellent combustion state during switching between high and low combustion, by a method wherein a ratio of an amount of primary air to an amount of secondary air is kept approximately at the same value even when the combustion state is varied. CONSTITUTION:Although, during high combustion, an electromagnetic solenoid 10 is demagnetized and a large opening 8 is released, during low combustion, which the solenoid 10 excited, the large opening 8 is closed by means of a variable damper 9, and air flowing in an intake chamber 3 through a small opening 7 is guided to a primary air duct 4 and secondary air duct 5. Thus, since the secondary air not flows through the large opening 8, an amount of the secondary air guided to both the two ducts 4 and 5 is decreased, and an amount of the secondary air is prohibited against too increase. This constitution stabilizes combustion, and prevents a burner body from being excessively cooled.

Abstract: PURPOSE:To keep the detection gains at an approximately fixed level by turning two signals sent from a photodetector into a single signal through time division to be approximately averaged and compared with a reference level and controlling the detection gain through a closed loop in response to the difference obtained from said comparison. CONSTITUTION:An analog switch 15 set at the next stage of preamplifires 3 and 4 switches two input signals in time division by a switch changeover clock signal 20 having a frequency sufficiently high than a control band. The output signals of both amplifiers 3 and 4 are synthesized into a single signal in time division is supplied as a numerator signal of a divider 7. The output of this divider 7 is transmitted through an LPF 17 which cuts off the frequencies sufficiently lower than the control band and approximately averaged. This averaged signal is compared with a reference level, and a signal corresponding to the difference of comparison is supplied to the denominator of the divider 7. The divider 7 functions to reduce its output in case the averaged signal is higher than the reference level. While the output of the divider 7 is increased if the averaged signal is lower than the reference level. Thus the detection gain is controlled through a closed loop.

Abstract: PURPOSE:To smoothly apply lining to a bent part, by increasing or decreasing the supply pressure of compressed air while a cable is pulled by constant tensile force when the reversed leading end part of a lining hose is stopped at the bent part of a pipe. CONSTITUTION:When the reversed leading end part 29 of a lining hose 5 is stopped at the bent part A2 of a pipe 2, the tensile force of a cable 16 is increased at first to be held to a constant value.
