Title: Amplifier output stage circuit
Inventor: HIYUU RON TEIEN
IPC: H03F3/30
Filed: 1989-12-06
Abstract: PURPOSE: To improve the stability of an output stage circuit of amplifier by driving a cascode stage by means of a low-output impedance driver stage which is an emitter follower. CONSTITUTION: During the half-cycle period of input signals in which an electric current is supplied to the base of an emitter follower-stage NPN transistor 11, an emitter follower supplies an emitter output current which flows to an NPN mirror connecting transistor 60 in a current gain stage through cascode- connected PNP transistor 50. In the other half cycle, the electric current flows out of the base of the transistor 11, absorbs an electric current from a PNP Darlington stage 20, and is supplied to the base of a transistor 30 through transistors 21 and 22. The transistor 30 generates an electric current to an output terminal 80. Since an output stage circuit itself is driven by means of an emitter follower stage which gives low-impedance drive, the circuit is intrinsically stable.

Title: Bag filter for exhaust gas treatment and operation method thereof
Inventor: SASAKI SATONORI
IPC: B01D53/56
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To make a bag filter usable at high temperatures and to reduce dust and nitrogen oxide in exhaust gas efficiently by using polyparaphenylenebenzobisoxazole fibers for the filter cloth of the bag filter. SOLUTION: In a bag filter for exhaust gas treatment in which the layer of a denitration catalyst such as metal oxide is formed on a filter cloth, polyparaphenylenebenzobisoxazole fibers excellent in heat resistance, strength, and modules of elasticity is used as the raw material of a filter cloth. In this way, catalytic denitration at a high temperature close to 300 deg.C, which has been impossible so far, can be implemented to reduce nitrogen oxides efficiently. However, when dioxin is produced as in the treatment of exhaust gas from a waste incinerator, the operation temperature is preferably controlled at 200-280 deg.C to minimize the production of dioxin.

Filed: 1993-12-20
Abstract: PURPOSE:To provide the channel selection device in which the effect of detuning such as drift due to a secular change or a temperature or a moisture on a tuning voltage stored in advance in a memory is prevented. CONSTITUTION:Tuning voltage data corresponding to each channel are stored in advance in a nonvolatile memory 8, and when the operator selects a channel, data are read from the nonvolatile memory 8 and a tuning voltage is outputted from a tuning voltage control circuit 7. On the other hand, an AFT signal is outputted from an AFT circuit 5, which corrects detuning. Simultaneously a drift arithmetic operation circuit 9 detects an upper limit and a lower limit or a voltage at a predetermined interval by using the tuning voltage after the detuning correction as a drift and the maximum value is stored in the nonvolatile memory 8. When a channel is selected again, the tuning voltage stored in the nonvolatile memory 8 is averaged with the upper limit voltage and the lower limit voltage and the result is outputted as the tuning voltage.

Title: Sense amplifier circuit
Inventor: TAKAYANAGI TOSHINARI
IPC: G11C7/06
Filed: 1989-12-12
Abstract: PURPOSE:To improve sensitivity, to enlarge an output amplitude and to take out two differential outputs by enlarging the ON current of a bit line fine control circuit and returning the potential of a bit line to a reference potential when the bit line potential exceeds the reference potential. CONSTITUTION:In a normal state, a fine current (<1muA) flows to an MOS TrP9 of a bit line potential fine control circuit 11 at a certain degree so that energy consumption can be ignored althought the current is larger than the leak current of a TrNL for bit line load of a bit line load circuit 80. Thus, the over precharge of the bit line is prevented. When the potential of the bit line is increased rather than an initial value, the ON current of the MOS TrP9 of the circuit 11 is enlarged and the potential of the bit line is discharged to return to the initial value. Then, the potential of the bit line is kept constant at the initial value. Thus, a sense amplifier 61 is operated at an optimum sensing point.
