Title: Pulverized coal firing boiler
Inventor: HIRAYAMA AKIRA
IPC: F23K1/04
Filed: 1980-07-15
Abstract: PURPOSE:To prevent the danger of dust explosion, suppress the generation of NOX, unnecessitate an air preheater and simplify the structure or the like by a method wherein the combustion exhaust gas is recirculated as a high temperature medium in the pulverized coal firing boiler. CONSTITUTION:The combustion exhaust gas is used as the high temperature medium for carrying, drying and burning of pulverized coal. The recirculating exhaust gas is sucked by means of a draft fan 10 through an combustion exhaust gas recirculating gas duct 14, the intake port of which is provided at the inlet or outlet of an economizer 3, mixed with the air from a bypass duct 12 and, after being controlled to suitable temperature, sent to a pulverizer 11. The coal is fed from a feeder 19 to the pulverizer 11, pulverized therewith, dried and carried by the high temperature combustion exhaust gas through a pipe 17 to a burner 20 and spouted from the burner 20 into a furnace 1 to be burnt. Because the combustion exhaust gas having  a low oxygen concentration is used for carrying and drying of the pulverized coal,  the danger of dust explosion is almost eliminated and also the burning itself proceeds under the condition that the exhaust gas having a low oxygen concentration inactivates around the pplverized coal, resulting in inhibiting the remarkable suppressing effect to the production of NOX.

Filed: 1991-04-25
Abstract: PURPOSE:To hear voices, which are inputted from an outside microphone, from the loudspeaker of a TV receiver without operating the voice mute circuit of the TV receiver even when a video signal is not transmitted to the TV receiver simultaneously with an audio signal inputted from the outside microphone at the magnetic recording and reproducing device which can transmit this audio signal to the TV receiver. CONSTITUTION:A signal detection circuit 20 detects the presence/absence of the video signal. When no video signal is detected, the test signal of a pseudo video signal is generated by a test signal generating circuit 16 and inputted through a switch 17 to a modulation circuit 18. This modulation circuit 18 simultaneously inputs the audio signal as well. The test signal and the audio signal are modulated at the modulation circuit 18 and inputted to a TV receiver 2 after mixing at a mixer 19. Thus, since a voice mute circuit 22 of the TV receiver 2 is not operated, the voices are outputted from the loudspeaker.

Abstract: PURPOSE:To curtail a driving circuit by providing a 1st part impressed with a voltage above the voltage to excite a nematic liquid crystal and a 2nd part for making multiplex driving. CONSTITUTION:A pair of polarizing films 7A, 7B are disposed on both faces of a liquid crystal cell.

The axes of polarization of said film on the front face are in the direction (b) at the part B and (c) at the part C and are nearly 90 deg. with each other so that the light is transmitted in the part impressed with the voltage. The important and large segments, therefore, have a sufficient degree of shielding and the small segments make multiplex driving. The driving circuit is thereby simplified.

Molding is performed by machining a cavity face so that the form errors are offset. That is, the cavity face is made by deviating it by -E1 with respect to the extent of E1 in a position in the direction y1 of each latitudinal line 34 of a lens 30. In the case of (i=1 to n), approximate functions of respective m-th degrees are found and, in the boundary of the region, derivated functions up to the (m-1)the degrees of the respective functions which hold the boundary therebetween are allowed to coincide with each other. Further, the position of the latitudinal line 34 and the radial change rate of a longitudinal line 35 are approximated in relation to each other over the whole region of the latitudinal lines. Thus, data for correcting molding are prepared.

Abstract: PURPOSE:To aim at reducing the number of workers for supplying magazines and enhancing the working efficiency of magazine supply, by providing such an arrangement that a magazine pusher is set at a low level to be prevented from reaching the area where the lowermost stage magazine and the upper adjacent magazine are fitted together in a cartridge so that the lower most stage magazine alone may be pushed out from the cartridge. CONSTITUTION:The level of a feed hole 21 in a cartridge 20 storing magazines 4 which are supported on a table 31 set therebelow, is slightly higher than the height of each magazine 4 from the support surface of the table 31, and therefore, only four magazines 4 are fed out at one time per magazine storing space 19. A pusher 32 moves along the top surface of the table 31 and enters into the cartridge 20 through the rear end section opposite to the feed hole 21 to push the rear end of the lowermost stage magazine 4 in the storing space 19. The pusher 32 is thin and the level of thereof is lower than the level of the area (a) where the lowermost stage magazine 4 and the upper adjacent one are fitted together, thereby it is possible to precisely and surely push the lowermot stage magazine 4 alone.
