Title: Method of coal liquefaction by hydrocracking
Inventor: KANDA NOBUYASU
IPC: C10G1/06
Filed: 1988-11-24
Abstract: PURPOSE:To liquefy coal by hydrocracking effectively, by using as a recirculating solvent a reformed oil which is obtd. by reforming and hydrogenating n-paraffin oil accumulated in the recirculating solvent in the presence of a metal catalyst carried by an active carbon and which thereby has an improved affinity and hydrogen donating capability to coal. CONSTITUTION:Liquefaction of coal by hydrocracking is carried out by supplying coal, a hydrocracking catalyst, a recirculating solvent and hydrogen to coal-liquefaction process. After the completion of the raction, the reaction product is separated into a product oil, a gas component contg. unreacted hydrogen, a solid residue contg. the catalyst, and the recirculating solvent in a separation process. Then, the recirculating solvent is separated into an n-paraffin oil and a dewaxed oil in the n-paraffin separation process. The separated n-paraffin oil is dehydrogenated and reformed in the presence of a dehydrogenation catalyst (a metal carried by an activated carbon) to give a reformed oil A. A mixed oil A of said reformed oil A with said dewaxed oil, a hydrogenated oil obtd. by hydrogenating said mixed oil A, said dewaxed oil, and a mixed oil B obtd. by mixing a hydrogenated product of said dewaxed oil with said reformed oil A are each used as said recirculating solvent.

Filed: 1991-10-16
Abstract: PURPOSE:To prevent useless consumption of a battery by switching a supply current to an amplifier circuit according to a current switching signal generated based on a detection signal from a detection demodulation means so as to decrease a gain of an amplifier circuit at a location where a reception electric field intensity is sufficiently large thereby decreasing a standby current. CONSTITUTION:When a RF signal is inputted to an input terminal 1, a demodulator 11 with a detection circuit demodulates signal into a base band AF signal and the signal is outputted from an output terminal 12, and this processing is the same as a convetional system, and the operation is implemented in this way. That is, the demodulator 11 is used to demodulate the RF signal into the AF signal and also to detect an input electric filed strength and to output a detection signal linearly increasing and decreasing in proportion to the strength to a switch control circuit 14, and the received detection signal is compared with a reference voltage by a comparator 16 built in the circuit 14. When the detected voltage exceeds a reference voltage a level of a current switching signal outputted to the current switch circuit 15 is switched from a low level to a high level and the supply current to an amplifier circuit 3 is switched by using an analog switch 17 built in the circuit 15.

Abstract: PURPOSE:To control the instantaneous drop of the internal power voltage at the time of turning on/off of an external power supply by providing a 2nd voltage detecting circuit which actuates a 1st selection circuit and a 3rd voltage detecting circuit which actuates the 2nd and 3rd selection circuits, respectively. CONSTITUTION:A voltage detecting circuit 7 controls the ON/OFF of a power supply where the threshold voltage V1 is set. A voltage detecting circuit 21 actuates a selec tion circuit 23 which uses an enable signal to which the threshold voltage V2 is set (V1>V2) and a prescribed potential as inputs. The selection circuits 24 and 25 have the threshold voltage V3 higher than the V1 and use an input/output bus and a pre scribed potential as the input, respectively. Then a voltage detecting circuit 22 actuates the selection circuits using the input/output bus and the prescribed potential as inputs, respectively. Therefore the signal lines securing the connection between the circuits 23 - 25 and a semiconductor storage device 20 are kept at each prescribed potential. Thus, the transient voltage is turned into the instantaneous voltage. Then it is possible to surely prevent the instantaneous voltage drop of an internal power supply of the storage 20 in the transient periods at rise and fall of a power supply as well as a latch-up state. In such a constitution, the high safety and the high reliability are se cured for the device 20.

Title: Variable attenuator
Inventor: YASUNAGA TAKESHI
IPC: H03G3/10
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To provide a variable attenuator in which current consumption is not increased, even when a gain is switched and an attenuation is changed an input output terminals are matched without a change in input output impedance. SOLUTION: Emiters of transistors(TRs) 1, 2 are connected in common and a signal is given to the TRs via a capacitor C1 and an output signal is extracted from collectors of TRs 3, 4 connected in common. The circuit is acted as an amplifier by turning on the TR 1 and turning off the TR 2 with gain control voltages 1, 2, and the circuit acts like the attenuator by turning off the TR 1 and turning on the TR 2 to switch the gain. The collector of the TR 2 is connected to ground via a resistor R3 to shunt a collector current of the TR 2 when the TR 2 is conductive so as to decrease the output gain thereby attenuating the input. Since the input and output section of the amplifier and the attenator is made in common, the input output impedance at gain switching is unchanged to obtain a matching.

Abstract: PROBLEM TO BE SOLVED: To obtain a bay window which can cut off water at its periphery with which a bottom plate, a sill and a building frame flashing get in contact by providing a space surrounded with the sill and the building frame flashing with a surface material for constructing the bottom of the base plate, and disposing a water-tight member in the whole periphery with which the surface material, the sill and a flashing get in contact. SOLUTION: In the case of assembling a bracket 25, a building frame flashing 61 and a surface material 23, the surface material 23 is pushed up by repulsive force of a water-tight member 65. Subsequently, a first locking part 23A of the surface material 23 is locked on a second locking part 63A in a groove 63 to enhance water tightness and air tightness. At the stage of riveting, the surface material 23 is prevented from slipping out from the groove 63 of the building frame flashing 61, thereby improving assembling operation efficiency. Then, at one side of the surface material 23 on the building frame side, the first locking part 23A of the surface material 23 and a second locking part 63A of the groove 63 are locked by repulsive force of the water- tight member 65.  Thus, water tightness and air tightness can be enhanced in a simple structure so as to prevent entering of rain water from a lower structural material 100 caused by blowing up.
