Title: Spread spectrum communication system
Inventor: FUKUMASA HIDENOBU
IPC: H04B1/69
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To prevent interference from being given to each other even when the information of different transmission rates is simultaneously multiplexed in the same frequency band by different spreading rates by generating an orthogonal code by multiplying the orthogonal codes of 2 rows and 2 columns to the orthogonal code using an M sequence and generating a spreading code sequence by multiplying the different M sequence further. SOLUTION: By using a hierarchical spreading code constitution method similar to a third technique, the code Mk of a code length 64 is prepared. It is the common generation method of an orthogonal matrix corresponding to the fact that the code length and a code number are respectively doubled by multiplying the orthogonal matrix of the 2 rows and the 2 columns to the orthogonal code of the M sequence. The code Mk of the code length 64 formed in such a manner is respectively orthogonal. Then, by multiplying (m) in the same phase to all the sequences of the orthogonal code Mk , the orthogonal code Gk of the new sequence is generated. In this case, in the case of using G2 at the spreading rate 32, the G2 , G3 and G4 -G7 to be generated are prevented from being simultaneously used by other users at the other spreading rate.

An electrolyte within a reverse U-shaped siphone strap is returned to the cylinder 1 from the small hole 4 according to accumulation of gas into the chamber 2. When the amount of accumulated gas reaches the position of the small hole 4, gas is pushed out as bubbles into the cylinder 1, and gas bubbles push up the electrolyte existing in this place in the cylinder 1 and rises, then exhausted together with the electrolyte from an upper end opening of the cylinder 1. At the same time, the pressure of the electrolyte in the cylinder 1 is reduced and the electrolyte in the bottom of a battery enters into the cylinder 1 and rises. The electrolyte with large specific gravity is pushed up to the upper part than the small hold 4 and stabilized in the position where it is balanced with the pressure of the electrolyte existing around the cylinder 1. These operations are repeated.

Filed: 1993-12-21
Abstract: PURPOSE:To check whether there is abnormality or not and efficiently carry out a characteristic test by applying right bias voltage to an element to be tested and detecting the current prior to a characteristic test of the element to be tested. CONSTITUTION:Each terminal of an insulated gate bipolar transistor(IGBT) 10, which is an element to be tested, is set so as to be brought into contact with a terminal of a testing apparatus. Under the control of a processing apparatus 52, a gate bias voltage generating circuit 32 and a collector voltage source 36 generate voltage respectively, so that slight collector current can flow in the case the IGBT 10 is normal. The collector current flows in a resistor 34 and an ADC (A/D converter) 46 supplies digital signals to the apparatus 52. The apparatus 52 determines that the IGBT 10 is short-circuited when the short-circuited collector current at the time short circuit occurs between the collector and the emitter of the IGBT 10 is almost the same as the actual collector current and determines that the circuit is opened at the time the actual collector current does not flow practically. That is, it is determined that the element to be tested has a defect.
