Title: Combustion device for pulverized coal
Inventor: ISHIDA TATSUJIROU
IPC: F23K3/02
Filed: 1983-09-03
Abstract: PURPOSE:To improve safety in the stable combustion as well as the transportation of the pulverized coal by a method wherein gas, whose O2 partial pressure is high, is mixed with another gas, whose O2 partial pressure is low, to correct the O2 partial pressure of pulverized coal transporting gas into the optimum value for burning the pulverized coal. CONSTITUTION:The pipelines 31, 32 of exhaust gas, whose O2 partial pressure is low, is connected to the upstream and downstream side of an air preheater 30 in a funnel 5. The paths 31, 32 are joined into a path 33 connected to a coal pulverizing machine 19. The pulverized coal, produced by the coal pulverizing machine, is transported by air stream to a burner for a boiler 1 through the path 20. On the other hand, the pipelines 36, 37 of air, whose O2 partial pressure is high, are connected to the upstream and downstream of the air preheater 30 in an air tunnel 12. The pipelines 37, 36 are joined into the pipeline 38 connected to a mixer 39 provided in the path 20. The amount and temperature of the exhaust gas from the paths 31, 32 are regulated to effect optimum drying in the coal pulverizing machine 19 and good transportation by air stream in the path 20 while the air, whose O2 partial pressure is high, is supplemented into the exhaust gas in the mixer 39 from the pipelines 36, 37 to send it into the burner and, thus, the stable combustion of the pulverized coal may be contrived.

Title: Switching regulator

IPC: H02M3/156
Filed: 1981-10-09
Abstract: PURPOSE:To obtain high efficiency and high responsiveness, by decreasing power loss at the input side through the provision of an inverted Darlington circuit and excluding the effect on the response of a collector capacitance of a control transistor (TR). CONSTITUTION:In applying an input voltage Vi, a base current is applied to a TR23 via a resistor 27, the TR23 turns on and also TRs 21, 22 turn on. The input voltage Vi is given to a capacitor 26 through an LC circuit and an output voltage V0 is increased. Since a Zener diode 24 has an operation resistance (normally several tens of ohms), voltage VZ24, a voltage across the Zener diode, is also increased in proportion to the increase in the output voltage V0. In this case, a constant current corresponding to (VZ24-vBE23)/R29 is applied to a collector of the TR23 and given to a base current of a TR22, where VBE23 is a base to emitter voltage of the TR23 and R29 is a value of a resistor 29.

Abstract: PURPOSE:To prevent wire breaking of gate metal by the large step difference of a mesa by implanting ions into a semiconductor layer under the step of a mesa so as to change it into the layer small in dry etching rate. CONSTITUTION:A high purity GaAs layer 2, an N-type AlGaAs layer 3 and an N-type GaAs layer 4 are accumulated on a semiinsulating GaAs substrate 1, and mesa etching is done to isolate an element. Next, with the resist 8 same as mesa etching as a mask, Al ions 5 are implanted. Next, the ohmic electrodes of a source and a drain are formed by deposition and alloying, and then with the resist 8 as a mask, dry etching is done so as to form a gate recess. Accordingly, for the GaAs layer 9 that Al ions 5 are implanted, the selection ratio with GaAs becomes large, the region of a gate pad that the resist is not applied is not etched deep, the difference in level at the mesa step never deepens, and the wire breaking of gate metal does not occur.

Title: Tape driver
Inventor: YUASA MIKIO
IPC: G11B15/093
Filed: 1979-12-14
Abstract: PURPOSE: To improve reliability by detecting a fault of a tape driving circuit on a vacuum column system by the continuance of a current flowing through a load resistance instead of a fuse.  
     CONSTITUTION: Level converter 65 is connected across load resistance 49 to enable detection at a logic level. In small-current drive, if the similar current as large- current drive flows, the logic level of converter 65 changes to a high or low level, but inputs to 3-input NAND gate 77 passed through integrating circuit 74 from inverters 72 and 73 are at the high level. However, since the device is being driven continuously with the low-level small current of signal 56 or 57, abnormality of the driving circuit is stored in flip-flop 78 and while signals 52W57 are made pseudo by using output signal 79, the driving circuit is stopped.

Filed: 1987-06-29
Abstract: PURPOSE:To enable the rapid and exact recording by a simple method at the time of recording and reproducing information by forming ruggedness of information recording patterns to an optical recording part and laminating a light reflecting material or optical recording material on a base material so as to cover the rugged parts. CONSTITUTION:The optical recording part 2 is formed on the specified base material 1.

Title: Control method for retarding or stopping strip in longitudinal traverse
Inventor: OKI MASATO
IPC: B65G43/08
Filed: 1978-12-29
Abstract: PURPOSE: To stop a strip at a preset position in a minimum time, by measuring the feed speed of the strip and a carrier table simultaneously and reducing the table speed while keeping their relative speed at around zero.  
     CONSTITUTION: As the rear end of a strip 3 on a carrier table 1 passes through a detector 7, the table is retarded after a time T which is calculated by an equation T=L/v 0 -v 0 /2μsg, where L represents stopping distance, v 0  feed speed of strip, μs static friction factor of table roller and strip and g represents gravitational acceleration. The strip speed VM and the table speed VT are simultaneously measured by speedometers 5, 6 respectively at the time of retardation to detect the speed difference ΔV=VM-VT, and an adding-subtracting controller 9 gradually decelerates the carrier table 1 in accordance with the speed difference and the detector's passing signal stops the table 1 without causing any slippage of the strip 3.

Abstract: PROBLEM TO BE SOLVED: To produce endotropine without accompanying danger of fire and explosion. SOLUTION: This method for producing endotropine comprises reducing tropanone with hydrogen activated by catalytic action of Raney nickel or Raney copper.
