Title: Spread spectrum communication equipment
Inventor: AKEBOSHI TOSHIHIKO
IPC: H04B1/707
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To keep spread code phase deviation within one clock by detecting a time difference by a time difference detecting means while using a clock having the opposite phase of a clock generated from a clock generating means. SOLUTION: When a received signal and a reference signal are inputted to a convolver 111 in the same code phase, a correlation peak appears at the intermediate point between the time point, when the received signal and the reference signal are to be inputted to the convolver 111, and an input time point. In opposition to this, when the received signal and the reference signal are inputted to the convolver 111 in different code phases, the correlation peak appears at the intermediate point of a code top between the received signal and the reference signal. Therefore, the time from the leading CG-START signal of a reference code to the correlation peak is measured and after the elapse of measured time, that point of time becomes the leading position of the received signal.  At such a time, as the time from the CG-START signal of the reference code to the correlation peak when the inverted clock of the clock of a VCO 106 is used, the time measurement error becomes within 1/2 of a clock.

Title: Endless tape housing device
Inventor: NAGAOKA KAZUO
IPC: G11B15/70
Filed: 1988-09-29
Abstract: PURPOSE:To house a lengthy tape by dividing a tape housing into plural movable parts, providing plural shifting means to shift the tape to mutually different directions, and providing a fixed plate to decelerate the tape at a joint part. CONSTITUTION:A tape 2 shifted through a first diaphragm 31 is made into an evenly dispersed condition by the elastic force of the tape itself decelerated by a boundary part H1 between the diaphragm 31 and a first fixed plate 40. Therefore, the tape is shifted onto a second diaphragm 43 without colliding with a side surface guide 51 in an F1 direction. Since a second fixed plate 48 is provided on an outlet 12b side as well, the tape 2 shifted from the diaphragm 43 is decelerated at a boundary part H2 between the diaphragm 43 and the fixed plate 48, and it does not collide with a segmenting plate 54. Thus, even when more tapes are housed in a tape housing area, the tapes are not damaged, and the exciting frequencies and amplitude of the diaphragm 43 are sufficient to be regulated to a constant value fixed according to tape speed regardless of the quantity and quality of the housed tape.

IPC: G09G3/36
Filed: 1990-09-18
Abstract: PURPOSE:To offer a driving method which simplifies the constitution of a circuit while obtaining the effect of weighting correction by forming plural divisional areas along a scan electrode and performing a weighting process while making the weight equal in the same area. CONSTITUTION:A correcting voltage whose level corresponds to the light and shade of data displayed on a scan electrode selected every time one scan electrode is driven is determined and this correcting voltage is added to a liquid crystal cell applied voltage while inverted in polarity between a positive voltage application mode period and a negative voltage application mode period. Then when the level of the correcting voltage is determined by weighting corresponding to the distance of a liquid crystal cell from the output of a scan driver 2, the divisional areas are formed along the scanning electrode and a weighting circuit 10 performs the weighting process while making the weight equal in the same area. Consequently, the light-shade rate of data displayed on the scan electrode is calculated by the areas along the scan electrode and the correction parameter can be weighted by the areas, so the effect of the weighting correction is obtained and simultaneously the constitution of the circuit is simplified.
