Title: Treatment of gas containing hydrogen sulfide
Inventor: OGAWA HIROSHI
IPC: B01J20/02
Filed: 1984-07-28
Abstract: PURPOSE:To efficiently perform regeneration at low temp., in a method for treating H2S-containing gas, by removing H2S by an adsorbent supporting oxide of one or more of Fe, Co, Mn and Mo and regenerating this adsorbent under heating in the presence of oxygen. CONSTITUTION:An adsorbent is prepared by supporting one or more of oxide of Fe, Co, Mn or Mo by a carrier comprising silica.alumina containing zeolite. H2S to be treated is reacted with metal oxide to be removed as metal sulfide. As the support amount of metal oxide increases, the volume of the adsorbent increases but, when increases to a certain degree, the adsorbing speed thereof is fallen and, therefore, the limit increase in the volume thereof is 30%. Regeneration is performed by heating the used adsorbent in the presence of oxygen but, because zeolite is used in the carrier, no sink-ring is generated and absorbing capacity is not lowered.

Title: Noise reduction circuit
Inventor: KITAMURA MASAHIRO
IPC: H03G11/08
Filed: 1992-06-16
Abstract: PURPOSE:To improve a noise decreasing characteristic of a noise reduction circuit. CONSTITUTION:A signal inputted from an input terminal 11 is inputted to the same phase input terminal of a coring circuit 1 and a mutual conductance circuit 2. An output of the coring circuit 1 through a capacitor 3, and also, an output of the mutual conductance circuit 2 are inputted to a buffer circuit 4, respectively. An output of the buffer circuit 4 is outputted from an output terminal 12, and also, fed back to an opposite phase input of the mutual conductance circuit 2. In the case an input signal level to the input terminal 11 is smaller than a blind sector level of the coring circuit 1, it becomes a grounded state by low impedance as an AC. When the blind sector level of the coring circuit 1 is set to the same level as amplitude of a noise, the noise is attenuated. Also, in the case an input amplitude level is larger than the blind sector level of the coring circuit 1, when the gain of the coring circuit is '1', an input signal exceeding a noise level is not attenuated and outputted.

The development is executed by the conveyance of the toner by a magnetic brush utilizing the magnetism of the particles and by the injection of an electric charge as the toner particles are conductive. The transfer is executed by the charging of the electric charge of the insulating wax near the surface of the toner particles and by the tackiness of the wax. The toner for which both systems of the development by electric charge injection and corona transfer are utilizable is thereby obtd.

Abstract: PURPOSE:To prevent the automatic constant-speed travel control from being executed unwillingly due to an operational error of a driver or an erroneous action of a computer or the like by inhibiting the execution of the automatic con- stant-speed travel control when the car speed is a low speed less than a predetermined value. CONSTITUTION:When the car speed detected by a car speed sensor 6 generating a pulse signal with a frequency proportional to the car speed is predetermined value or higher, the period of the output voltage V1 of te diode 101 of a switching drive circuit 10 is relatively short and the period of the output voltage V2 of HPF102 is also relatively short. Accordingly, the output voltage V3 of an integration circuit 104 exceeds the threshold voltage of Tr 106, the collector current I0 flows through Tr 106, a relay switch 9 is turned on, and the automatic constant-speed control can be performed via a control circuit 5. On the other hand, when the car speed is less than the predetermined value, the collector current of Tr 106 is nearly zero, the relay switch is turned off, and the control circuit is made inoperative.
