Filed: 1989-04-06
Abstract: PURPOSE:To shorten time required from the change of an ON/OFF signal up to the sending of a power supply control signal based upon a serial data bus system to a power supply by deciding whether a current sequence is an ON sequence or an OFF sequence at first. CONSTITUTION:When plural ON/OFF signals 151 to 15n outputted from a master control device 11 are inputted to a power supply control device 12, the circuit 12 inputs the data of current plural ON/OFF signals, i.e. the current data, to a register in its microprocessor 12a and also inputs the data of the preceding plural ON/OFF signals, i.e. the succeeding data, similarly to the register in the microprocessor 12a. Thus, whether the current sequence is the ON sequence or the OFF sequence is decided from the input data of the plural ON/OFF signals 151 to 15n and the stored data of the preceding input. Thereby, respective changes of plural ON/OFF signals can be detected in the descending priority order in each sequence. Thus, the time required from the change of the ON/OFF signal up to it serial data bus system transmission to the power supply can be shortened.

Title: Digital demodulation circuit
Inventor: SASAKI TAKAHIRO
IPC: H04L27/38
Filed: 1994-04-25
Abstract: PURPOSE:To allow the digital demodulation circuit to demodulate data with high accuracy over a broad band at a low cost with miniaturization. CONSTITUTION:A quadrant discrimination circuit 23 discriminates a quadrant of an orthogonal demodulation signal on a phase plane and generates a load clock depending on the result of discrimination. An error detection circuit 27 stores the amplitude of the orthogonal demodulation signal depending on the load clock and provides the output of a difference between the amplitudes as an orthogonal error in an orthogonal multiplier circuit 25. A carrier recovery circuit 26 generates a reference carrier and an orthogonal carrier as a recovered carrier depending on the orthogonal error. A complex multiplier circuit 21 applies phase synchronization demodulation processing to a quasi-synchronization orthogonal demodulation signal based on the recovered carrier. Thus, the signal is demodulated with high accuracy over a broad band at a low cost with a small sized circuit.

Abstract: PROBLEM TO BE SOLVED: To obtain a heat-resisting semiconductor device of low resistance by a method wherein a titanium silicide film is formed on the surface of a silicon conductive film and then the substrate is heat-treated in a non-ozidizing atmosphere and after that, an oxide film is formed in an oxidizing atmosphere in a specified temperature range and an insulating film is deposited on the oxide film and then a heat treatment is conducted and finally an interconnect layer is formed on the insulating film through the titanium silicide film. SOLUTION: On a silicon substrate 1, an element isolation oxide film 2 and a gate insulating film 3 and a polycrystal silicon film 5 are formed. Then, a quasi-stable titanium silicide film 6 of a C49 phase is formed on the gate insulating film 3 and the polycrystal silicon film 5. Then, this substrate is heattreated at a specified temperature in a nitrogen atmosphere to reform the titanium silicide film into a completely stable and low-resistance titanium silicide (TiSi2 ) film 6 of a C54 phase. After that, the substrate is heat-treated at about 200-400 deg.C in an oxidizing atmosphere. Due to this low temperature heat treatment, only the surface of the TiSi2 film 6 can be oxidized and an oxide film 7 is formed without oxidizing grain boundaries inside the TiSi2 film 6.  By this, the aggregation of TiSi2 can be suppressed and the oxidization of the grain boundaries inside the TiSi2 can also be suppressed and thereby a low-resistance TiSi2 film which has an excellent heat resisting property can be obtained.
