Filed: 1990-07-18
Abstract: PURPOSE:To build a drop tower relatively economically in a place convenient for traffic by providing a drop hole having a free capsule dropping section in the upper part and a control section in the lower part perpendicularly to the ground in a high-rise building. CONSTITUTION:A drop hole 2 is provided perpendicularly continuously to the ground 6 in a part of a high-rise building 1. By dropping freely a capsule 3 through a free drop part 2a of the upper portion of the drop hole 2, slight gravity for an experimental sample in the capsule 3 is generated. A control section 2b incorporating a braking device 4 therein is provided in the lower part of the drop hole 2 to decelerate the dropping speed of the freely dropping capsule 3 and stop it. Also, a capsule setting chamber 5 for setting the capsule 3 to the drop hole 2 is provided on the upper side of the drop hole 2. The ratio of the free drop section 2a to the braking section 2b in the length is about 75:25. For example, assuming the height of the building 1 is about 200m, the height of the drop section 2a is about 148m and slight gravity time generated in the sample is about 5.5 seconds, so that the drop hole 2 can be effectively built in the building 1.

Filed: 1992-07-17
Abstract: PURPOSE:To make the miniaturization, weight reduction, and cost reduction possible by setting and fixing other permanent magnet between other permanent magnets. CONSTITUTION:This is a linear motor where a needle 16 is arranged capably of shifting in longitudinal direction on the surface of permanent magnets 14 where a plurality of permanent magnets are arranged so that different poles may appear alternately in longitudinal direction. And, permanent magnets 14a are arranged separately, and also other permanent magnets 14b being magnetized in longitudinal direction are set and fixed periodically between adjacent permanent magnets so that the same poles may come close to each other, thus a continuous row of permanent magnets is made. Hereby, a closed magnetic circuit is made, and the magnetic saturation in a center yoke 6 and a side yoke 5 can be prevented. Accordingly, the quantity of magnetic flux contributable to thrust can be secured or increased. On the other hand, a means for increasing the sectional area of the yoke for securing the quantity of magnetic flux becomes needless, and downsizing and weight reduction becomes possible.

Title: Packet configuration method and packet receiver
Inventor: OKANOUE KAZUHIRO
IPC: H04L27/00
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To provide a training series to demodulate a received packet by estimating correctly a frequency offset and a communication channel impulse response even when a timing error takes place in the detection of a transmitted packet in a communication form (a LAN(Local Area Network) is a typical form) where a packet is asynchronously transmitted. SOLUTION: A training series 101 is configured by using K-sets of consecutive series 100-1-100-K consisting of same N symbols. Even in the case of a communication channel where inter-code interference takes place, reception signals different by optional N-symbol time are signals where only a phase difference caused by a frequency offset between a transmitter and a receiver differs by using the training series as above. Thus, even when there is an error in the timing to detect a head of a packet, the frequency offset is estimated.
