Abstract: PURPOSE: To effectively utilize hot exhaust gas from manufacture of CaO and to manufacture CaC 2  at a lower cost than that of an electric furnace process by driving a turbine with steam generated by utilizing the hot exhaust gas; actuating an air compressor; and recycling O 2  separated from compressed air to combustion of fuel for manufacture of CaC 2 .  
     CONSTITUTION: Lime raw material such as quick lime and carbon material such as coke are mixed so that the molar ratio of C/CaO becomes 1W4, and mixed raw material 1 is continuously charged into CaC 2  formation furnace 2. On the other hand, fuel supplied 4 to burner 3 from fuel tank 5 is burned with O 2  or O 2 -enriched air, and raw material 1 is reacted in the presence of the generated hot gas of above 2000°C to obtain CaC 2  10. Exhaust gas of above 1500°C from furnace 2 is introduced into waste heat boiler 13 to generate superheated steam of 37 kg/cm 2  and 400°C, which is then introduced into steam turbine 17 to drive turbine 17, producing rotation power. Using this power an air compressor is actuated to compress air, and the compressed air is separated into N 2  and O 2  with air separator 11. This O 2  is fed to O 2  gas holder 12 and supplied 6 to furnace 2.

Inventor: SUDO YUKIO
IPC: H03L7/02
Filed: 1985-04-01
Abstract: PURPOSE:To expand the locking range of AFC and to improve the accuracy by providing a subtraction circuit generating a difference signal between an output of the 1st detection circuit detecting an output of a low-pass filter and an output of the 2nd detection circuit detecting an output of a high-pass filter. CONSTITUTION:The low-pass filter LPF having a cut-off frequency fL equal to or lower than a prescribed intermediate frequency f0, the high-pass filter HPF having a cut-off frequency fM equal to or higher than said prescribed intermediate frequency f0, the 1st detection circuit detecting the output of the low-pass filter and the 2nd detection circuit detecting the output of the high-pass filter are provided, and the subtraction circuit generating a difference signal between the output of the 1st detection circuit and the output of the 2nd detection circuit is provided. The characteristic curve of the low-pass filter LPF and the characteristic curve of the high-pass filter HPF cross together in the vicinity of the prescribed intermediate frequency f0. Since the pass band width of the low-pass filter LPF is ideally a band between a DC and the cut-off frequency fL and the pass band width of the high-pass filter HPF is ideally a band between the cut-off frequency fM and an infinite frequency, the locking range is expanded sufficiently.

Title: Belt-type continuously variable transmission
Inventor: TAKANO HIROSHI
IPC: F16H9/18
Filed: 1991-03-07
Abstract: PURPOSE:To make a pump compact and save energy by interposing check valves for allowing the flow of a fluid only to the control valve side, in a pitot tube line and a pump line for connecting pitot tube and a pump respectively to the control valve in a belt type continuously variable transmission for an automobile or the like. CONSTITUTION:Check valves for allowing the flow of a fluid only to the control valve 33 side are respectively interposed in a pitot tube line 34 between a pitot tube 12 and the control valve 33, and in a pump line 35 between a pump 16 and the control valve 33. Accordingly, when the rotating speed of an input shaft 2 is small, the pitot pressure sensed by the pitot tube 12 is smaller than the pressure of the pump 16, so that the output fluid of the pump 16 is supplied to a hydraulic cylinder 28 through the control valve 33, a cylinder line 36 and a fluid passage 25. Inversely, when the rotating speed of the input shaft 2 becomes large, the pitot pressure becomes larger, so that a fluid in a fluid reservoir part 11 is supplied to the hydraulic cylinder 28 through the pitot tube line 34.

Abstract: PURPOSE:To increase the output current amplitude without making an C(T) operation disabling mechanism unreliable after the T(C) output is turned on, by using a gate having a large output current amplitude and superior in the separation of input from output. CONSTITUTION:The power supply voltage is increased up to 11.2mV from 0mV at the 100ps rise time in the state of the T input 13 is set at ''1'' (current value 0.4mA) and the C input 14 is set at ''O'' (current valve 0mA). Then the power supply voltage is kept at 11.2mV. Then a switch Q1 and then Q3 are switched. The steady value of output current T*15 is set at 0.38mA, and 90% of this steady value is attained at a time point 201ps. This fact is shown by a simulation. In such a way, the power is supplied auxiliarily to output stage gates Q3 and Q4 with a shunt resistance 132. This increases both the speed and the output amplitude.

Title: Ink jet head of ink jet recorder
Inventor: HAYASHI HIROKAWA
IPC: B41J2/175
Filed: 1978-06-07
Abstract: PURPOSE:To prevent injection defect of ink liquid by heating the ink flowed into an ink jet head to surely expell the air bubbles in the ink liquid then cooling the ink liquid having been heated again down to ordinary temperature. CONSTITUTION:Ink liquid having flowed into an ink liquid distributing chamber 2 through ink liquid influent port 9 is first heated by a heating element 14 at the time when it flows in the inside of the ink liquid influent chamber 2a. As a result, the air bubbles in the ink liquid grow, rise rapidly, arrive at the air layer in the upper part of the ink liquid distributing chamber 2 and are exhausted to the outside through an exhaust hole 12. The ink liquid reaches the upper part of an intermediate chamber 2b from the ink liquid influent chamber 2a and flows toward the lower part of the intermediate chamber 2b and therefore entering of the air bubbles into the effluent chamber 2c does not occur. The ink liquid is cooled down to about ordinary temperature by a cooling element 16. In this way, the injection defect of the ink liquid owing to the mixed presence of the air bubbles may be prevented.

Accordingly, the relaxation of the concentration of the electric field and breakdown due to a punch-through or a reach-through by the depletion layer and the inversion layer can be prevented, thus increasing breakdown strength without augmenting the area of a pattern.
