Title: Direct spread spectrum spread communication system
Inventor: HIKOFUSA KEIJI
IPC: H04B1/7093
Filed: 1993-12-27
Abstract: PURPOSE:To conduct two-phase/four-phase shift keying demodulation through the use of spread spectrum in one bit quantization by providing a digital differential phase shift demodulator and the like processing the outputs of a pair of a digital matched filters correlating respective signals quantized by A/D converters. CONSTITUTION:A reception signal s(t) is amplified and a frequency is converted. Then, carriers which are carrier-reproduced and are mutually orthogonal are multiplied and synchronous and orthogonal base band components are generated. The orthogonal base band signals are one-bit quantized by a pair of A/D converters 5 and 6 having hard limitters. Then, the signals are inputted to the corresponding digital matched filters 7 and 8 so as to obtain a correlation peak. Differential phase shift demodulation is conducted by a digital phase shift demodulator 9 by using correlation outputs so as to obtain information. When C/N is low, demodulation can be conducted with the error rate characteristic of one bit quantization with carrier a synchronization. When C/N becomes higher, demodulation can be conducted with carrier synchronization.

IPC: H04Q7/30
Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To provide a radio base station capable of turning a null point to a mobile station other than an object mobile station even at the time of a reception error. SOLUTION: This radio base station 100 is the radio base station of an adaptive array system for forming a directional pattern for directing one mobile station and turning the null point to the other mobile stations for each mobile station and simultaneously performing spatial multiplex communication with the plural mobile stations by using a directional parameter group for directional pattern formation obtained from reception signals at the time of transmission as well. When an error detection part 81 detects the reception error, a forced null instruction part 82 instructs a forced null weight calculation part 62 and thus, a parameter group for turning the null point to the other mobile stations is calculated for the mobile station causing the reception error.  A signal adjustment part 51 weights signals to the mobile station by using the parameter group and thus, the direction pattern is formed in antennas 10-40.

Title: Temperature detecting circuit and temperature detecting method
Inventor: IMAI HARUYUKI
IPC: G01K7/01
Filed: 1999-11-22
Abstract: PROBLEM TO BE SOLVED: To obtain a temperature measuring circuit capable of precisely measuring the temperatures of a transformer and a coil. SOLUTION: Since a winding 4 for detecting temperature which mutually cancels inductance component with a secondary winding 2 of a transformer 1 is arranged, and one end P of the secondary winding 2 and one end M of the winding 4 for detecting temperature are connected with a resistance measuring circuit 3, a voltage is not applied almost at all across the measuring terminals of the resistance measuring circuit 3. Consequently, the resistance measuring circuit 3 can measure the resistance summing the resistance between both ends of the secondary winding 2 and the resistance between both ends of the winding 4 for detecting the temperature without being affected by a secondary side voltage of the transformer 1, measuring precision of the resistance is improved, and a high voltage breakdown structure of the resistance measuring circuit 3 is made unnecessary.  Since the resistance can be measured while the transformer 1 is operated, temperature change of the transformer 1 can be detected in realtime.
