Title: Method and device for spraying slurry-like fuel
Inventor: KATAOKA SHIZUO
IPC: C10L1/32
Filed: 1986-01-17
Abstract: PURPOSE:To reduce an amount of gas for spray working and to improve combustion efficiency, by a method wherein coal and water slurry (CWS) is fed through a conduction passage with a pressure, a fission atomization, wherein CWS is injected at a throttle part to a target for collision, and atomization, wherein an eddy flow is collided with a groove formed in the outer periphery of the target, take place. CONSTITUTION:Coal and water slurry (CWS) is fed with a pressure through a conduction passage 11 to a single hole 13 of a throttle part, the CWS is throttled at the throttle part to form a high speed single liquid column, which is injected in a mixing chamber 15. The liquid column is collided with a target 18 positioned facing the single hole and is fission-atomized for primary atomization. An eddy flow is exerted on the CWS within the mixing chamber 15 by means of atomized gas fed through a flow passage 14 communicated with a gas conduction passage 12 for atomization. The eddy flow is collided with a groove, formed in the outer periphery of the target, when it flows through the mixing chamber, and is agitated for promotion of atomization. The CWS is sprayed through a spray nozzle 16 into a furnace 19 in a state to be sufficiently atomized. This constitution enables improvement in combustion efficiency of the CWS without needing quantities of gas for spray working.

IPC: G11C17/00
Filed: 1986-01-17
Abstract: PURPOSE:To speed up the read by providing a separation N-channel MOSFET to a data line so as to turn off at write operation. CONSTITUTION:Gates of separation MOSFETs Q3 or the like are connected in common to a control line to which a control voltage Vig is supplied, sources are used in common to constitute a common source line CS. The common source line CS is coupled to an output terminal of a common source line drive circuit DVR. The circuit DVR drives nearly to a power voltage VCC level to the line CS at erasure and the line CS is driven to a ground level nearly at the circuit at read operation. Thus, when a well WELL is brought into a power supply voltage VCC level at erasure, the forward bias of the junction between the electrode of the FET Q3 coupled to the line CS and the well WELL is prevented. Further, a current path required for the read is formed between the line CS and a ground point of the circuit. The MOSFETs Q7, Q8 are brought nearly into a low level close to zero voltage at the read and write.

Title: Output circuit
Inventor: KANEZAKI KOUICHI
IPC: H03K19/003
Filed: 1980-01-22
Abstract: PURPOSE:To prevent the breakdown of a transistor, by securing an assured cut-off when a conduction is given to the current supplying transistor of a totem pole circuit by a current absorbing transistor. CONSTITUTION:The transistors 4 and 10 plus the current absorbing transistor 5 are in conductive state when the input signal applied to the input terminal 1 has an H level. When the input signal is changed to an L level, the transistor 5 is broken to give a conduction to the transistor 6. In this case, R12>2R15 (VCC-VBE)/VBE is satisfied, where VBE is the base-emitter voltage of the transistor 5, and R15 and R12 are resistance values of the resistances 15 and 12 respectively. As a result, the transistor 5 is cut off to give the first conduction to the transistors 6 and 9. Thus a simultaneous conduction is eliminated between the transistors 6 and 5.

More specifically, the TB is mixed with an electron accepting substance, and the TR is mixed with organic amine which is operative to react the electron accepting substance thereby to develop a complementary color of red (Here, the combination may be reversed.). Upon development, the above two are reacted by the resultant heat or pressure so that the complementary color is added to the red toner TR in the black range so as to convert the TR into a black color thereby to eliminate the color mixing.

Abstract: PURPOSE: To attain the suppression of detection distortion as well as the reduction of a beat tone by suppressing the generation of a higher harmonic component at a detection time by using transistors, supplied with signals out of phase with an AM intermediate frequency signal, in parallel.  
     CONSTITUTION: The collector-emitter circuit of Tr7 is connected in parallel to the collector-emitter circuit of transistor (Tr)2, and Tr2 is applied at its base with a signal, out of phase with an AM intermediate frequency signal applied to input terminal 1, from terminal 8.
