Patent JP-S63206023-A (JP)
Title: High voltage switching circuit
Inventor: WADA TAKAMICHI
IPC: H03K17/04
Filed: 1987-02-23
Abstract: PURPOSE:To attain high speed operation by connecting a drain of other two PMOSFET connected in series to a common gate of an inverter comprising a PMOSFET and an NMOSFET connected in series between a power supply and ground. CONSTITUTION:When a control input signal A is at 0V, the output of an inverter 101 stays at a level of power voltage VDD, a drain potential B' reaches the voltage VDD through the NMOSFET 102 and the gate of the PMOSFET104 is turned on. The PMOSFET106 and the NMOSFET103 form an inverter, a common potential B' is applied to the gate and an output terminal 108 outputs a signal C' of 0V. When the input signal A reaches the voltage VDD, the inverter 101 outputs 0V to decrease the voltage B' from the voltage VDD to 0V quickly. The PMOSFET105 is turned on, a current flows from a power supply VPP and the signal C' at the output terminal 108 goes to the voltage VPP. Thus, the output signal C' is switched quickly in response to the change in the input signal A.

Abstract: PROBLEM TO BE SOLVED: To provide a floating point arithmetic unit which includes a cancelation discrimination means to use a BCD(binary coded decimal) operation if the possibility of cancelation is recognized and therefore obtaining an accurate result including no cancelation error to prevent much deterioration of the processing speed. SOLUTION: The arithmetic expression inputted via an arithmetic expression input means 1 is analyzed by an arithmetic expression analysis means 2 in regard to the arithmetic type and the numerical data. Then an arithmetic control means 3 analyzes a series of arithmetic expressions of arithmetic operations into combinations of binomial operations. When the binomial operations are carried out, a cancelation discrimination means 4 discriminates whether the cancelation occurs or not. If the possibility of cancelation is recognized, a data conversion means 6 converts the numerical data into a BCD form and the data of the BCD form are calculated by a BCD calculation means 52. If the possibility of cancelation is not recognized, the numerical data are calculated by a floating point calculation means 51.  The obtained arithmetic result is reflected on the original arithmetic expression and the binomial operations are repeated until the arithmetic expression is over.

Filed: 1988-02-24
Abstract: PURPOSE:To obtain an arbitrary high-frequency characteristic and to improve production efficiency by using low melting point glass contg. specific ratios of B2O3, ZnO and PbO as a reinforcing material. CONSTITUTION:The low melting point glass contg. 3-15wt.% B2O3, 3-10wt.% ZnO, and the balance PbO is used as the reinforcing material.

IPC: G06F3/05
Filed: 1988-02-22
Abstract: PURPOSE:To economically constitute a D-A converter by directly converting the digital signal of a remainder number system to an analog signal without converting it to a binary digital signal. CONSTITUTION:When a digital input signal S1 of the remainder number system is inputted to the D-A converter, a remainder number system signal supply circuit IN informs a timing control circuit 1 of the input of the digital signal and supplies respective digits of an N-digit remainder number system signal, where moduli of respective digits are mi (i=0, 1...N-1), to digit coincidence circuit 3-N. The timing control circuit 1 generates a conversion start signal S2 which indicates the start of D-A conversion operation. N-number of modulus counters start the counting operation by the signal S2 and perform the counting operation with moduli mi, and respective digits of the counted result signal are sent to digit coincidence circuit 3-N. When the remainder number system signal and the counted result signal coincide with each other, circuit 3-N send digit coincidence signals of respective digits to an all digit coincidence circuit 3 to generate a coincidence signal S3.

Title: Pm decoding circuit with pseudo data protective function
Inventor: YOSHINO TOYOHIKO
IPC: H04L25/49
Filed: 1988-02-23
Abstract: PURPOSE:To improve transmission quality by selecting and outputting an input from a serial/parallel conversion circuit(S/P) when an input data is normal and an input from a storage means when any fault takes place in the input data. CONSTITUTION:A discrimination processing means 20 outputs 1 when two input bits 1, 0 or 0, 1 and outputs 0 when 1, 1 or 0, 0. Thus, a selection means 40 uses a control signal being the output of a discrimination processing means 20 when the data is normal to switch the output data of the S/P 10 to the input side and outputs the result. Then a data of a prescribed number of frames is stored in a storage means 30. On the other hand, when the outputs of the S/P 10 are 0, 0 or 1, 1 due to transmission line error or the like, the selecting means 40 uses the control signal being the output of the discrimination processing means 20 to branch the output of the selection and to switch the data read from the storage means 30 storing the data of a prescribed number of frames to the inputted side. Thus, even if any fault takes place in the data, the data of prescribed preceding frame is outputted to protect the system.

Abstract: PURPOSE: To prevent control abnormality and the damage of an unit even of noise caused by the existence of floating capacitance occurs when transmitting signal between two circuits through an insulated transmission means such as a photocoupler. CONSTITUTION: A power conversion driving controller (first circuit) 1 and an IGBT gate drive controller (second circuit) 5 transmit signals through the photocoupler (insulated transmission means) 8. When noise current entering the secondary side of the photocoupler 8 is set to be Ix3 , current flowing into a power supply side line to be Ix31 and current flowing into a signal line side to be Ix32 , Ix3 =Ix31 +Ix32 is realized.

The synthesis impedances Cx and Cx1 on the capacitance of both lines against high frequency signals are almost equal. When the resistance values R1 of the resistors 6 and 6A are set to be sufficiently larger than the resistance value R2 of a resistance 4, Zvcc=Zx is realized, and Ix3 can be reduced.
