Title: Liquefaction of coal using catalyst fired by fluidization
Inventor: HAYASHI SHIGEYOSHI
IPC: B01J27/043
Filed: 1991-10-11
Abstract: PURPOSE:To liquefy coal using a catalyst which has stable catalytic activity with a small lot-to-lot variation and can be produced at low cost. CONSTITUTION:The title process is characterized by using a catalyst prepared by firing ferrous sulfate dihydrate, obtained by treating a slag with sulfuric acid and recrystallizing the formed product at 64 deg.C, at 250-1000 deg.C in the presence of recovered sulfur in a fluidized bed oven. An iron sulfide catalyst having a high activity and a controlled particle diameter can be obtained by firing a raw material such as a slag, a dust or an iron ore by fluidization, and therefore its production cost is very low. According to this process, the amount of organic gases formed is not very large, and the amount of low-boiling oils formed is large.

IPC: H01L21/8232
Filed: 1990-10-01
Abstract: PURPOSE:To improve the power supply voltage allowable width in the matching of an external input signal level and the logic level of an internal BFL circuit by incorporating a VSS1 power supply fluctuation suppressing means and an input signal DC bias fluctuation compensating means into a logic level conversion circuit. CONSTITUTION:Let a negative voltage be a positive polarity with respect to a power supply VDD taken as a reference level (0V), then the relation of equation V1=VSS1+n.Vf is satisfied. V3 is calculated as V3=VIN-inverse of VIN + n2Vf+V1- n3 and Vf=VSS1+(VIN-inverse of VIN)+(n1+ n2- n3). From the equation of the Vf, the following equation is obtained. V3=VSS 1+(VIN-inverse of VIN), where the inverse of VIN is the output potential of the input signal VIN after passing through a low pass filter and concretely the time mean value of the VIN. When the input signal is equal to the time mean value, because of the relation of VIN=inverse of VIN, the relation of V3=VSS1 is satisfied. So long as all FETs Q11-Q16 are in the saturation region, no other factor than the VSS1 is included in the output level V3 at an output terminal 16 inputted to the BFL circuit 9 in the inside of the IC.

Abstract: PROBLEM TO BE SOLVED: To securely perform the setting of registration mode by setting the registration mode on the basis of the registration requiring signal transmitted from a transmitter, besides the operation of an existing vehicle switch, and set the severe setting condition. SOLUTION: A predetermined abnormal operation of a predetermined vehicle switch is performed by a user. A predetermined operation different from a case for transmitting the door lock/unlock signal is performed by the user. Consequently, when the registration requiring signal from a transmitter 1 is received by a receiver 2, the receiver 2 side is switched to the registration mode as the first time. Namely, registration mode is set on the basis of the registration requiring signal sent from the transmitter 1, besides the operation of an existing vehicle switch. Registration mode setting condition is thereby set severe, and the registration mode can be more securely set.

Title: Accelerating device for operation between dual port memories
Inventor: BABA SHIGEMI
IPC: G06F12/00
Filed: 1985-11-26
Abstract: PURPOSE:To accelerate the operation between dual port memories by inhibiting the access request given from other CPU by means of a detecting means which is set when an inter-memory arithmetic request is detected and then reset when no inter-memory arithmetic request is received for a fixed period. CONSTITUTION:A dual port memory receives the refresh requests of both CPU 1 and 2 as well as an operation request between a memory of the CPU 1. When the inter-memory operation request C is received, a D-FF 17 is set and the request of the CPU 2 is inhibited by an AND gate 10. Then a D-FF 4 is cleared with the signal of an ENDCPU 1 when the request given from the CPU 1 is through. Thus a monostable circuit 11 starts its actuation. The D-FF 17 is reset at an edge when a fixed time passed and then the gate 10 is opened. However an AND gate 15 does not transmit said edge due to the output of the D-FF 4 in case the inter-memory operation request is received again before a fixed time passes. Thus the D-FF 17 is not reset.
