Title: Recovering method for hydrogen from coke oven gas
Inventor: YAMADA TOMIAKI
IPC: B01J20/20
Filed: 1978-12-08
Abstract: PURPOSE: To enable long-term continuous operation and economically recover hydrogen from coke oven gas by contacting the coke oven gas to activated carbon and adsorption-separating hydrogen with zeolite.  
     CONSTITUTION: Coke oven gas is contacted to activated carbon to remove trace amts. of pollutants, and hydrogen is recovered from the gas by adsorption separating operation using zeolite as an adsorbent as follows: the gas is passed through a fixed bed of zeolite at ordinary temp. or below under ordinary press. or above to adsorption-separate the constituents of the gas other than hydrogen, and the hydrogen flowing out of the bed is recovered. When the zeolite reaches saturation adsorption, it is regenerated to repeat adsorption. At this time, a plurality of adsorption beds are parallelly arranged and operated so that zeolite is regenerated in one bed and adsorption is carried out in other bed, thus continuously recovering hydrogen.

Title: Differential amplifying circuit
Inventor: NAKAZAWA KIKUO
IPC: H03F3/45
Filed: 1988-06-20
Abstract: PURPOSE:To reduce the amplitude of the produced ringing noise by securing the connection with the use of a capacity element between the emitter of a 1st transistor TR and the collector of a 2nd TR as well as between the emitter of the 2nd TR and the collector of the 1st TR respectively. CONSTITUTION:A pair of transistors TRQ1 and Q2 are prepared. Then the capacitors CX1 and CX2 are connected between an emitter E1 of the TRQ1 and a collector C2 of the TRQ2 as well as between an emitter E2 of the TRQ2 and a collector C1 of the TRQ1 respectively. When the input signals are applied to the terminals I1 and I2, the base current produced at both TRQ1 and Q2 via the feedback capacities Cr1 and Cr2 have the feedback loops shorter than that of a conventional circuit. Thus the feedback loop L does not pass through an impedance element Z and passes the TR by a single stage only and therefore the transmission delay time of the loop L is also reduced. Then the frequency is increased in inverse proportion to the cycle. As a result, the frequency-gain characteristics are more smooth in a high frequency area and the high frequency noises such as ringing noise can be reduced.
