Title: Lsm system adaptive array antenna system
Inventor: OOSHIMA HITOSHI
IPC: H01Q3/26
Filed: 1993-11-29
Abstract: PURPOSE:To attain excellent reception by including a pattern signal in a radio wave signal in time division multiplex with a data signal at a predetermined interval and extracting a pilot signal subject to time division multiplex by an extract means to eliminate a disturbing signal. CONSTITUTION:Only a pilot signal is extracted from a symbol sampler output by a pilot sampler 41. The extracted pilot signal is latched sequentially by a shift register 43 and the pilot signal having been already latched is shifted every time a new pilot signal is extracted. The pilot signal latched in the register 43 is fed to corresponding multipliers 451-45n, in which the signal is multiplied with a numeral signal from a numeral generator 46. The result of multiplication is added by an adder 47, a complex conjugate is taken by a complex conjugate circuit 51, from which a resulting phase compensation signal is obtained. Furthermore, the pilot signal latched in the register 43 is squared by multipliers 481-48n, the results are added by an adder 49 and its reciprocal is obtained by a reciprocal circuit 52, from which an amplitude compensation signal is obtained.

Title: Device for detecting gas dissolved in oil
Inventor: ISHIBASHI ATSUHIKO
IPC: G01N21/35
Filed: 1992-11-09
Abstract: PURPOSE:To obtain a gas separating filter which can sufficiently withstand a remarkably high oil pressure and can efficiently separate a dissolved gas from oil in a short time by constituting the filter of a cylindrical supporting member made of a porous metal and a semi-permeable membrane coating the external surface of the supporting member. CONSTITUTION:The inside of the title detecting device is divided into a front and rear chambers separated by an intermediate partition plate 18 and a gas separating filter is constituted in one chamber (on left side of the figure) by installing a cylindrical supporting member 19 made of a porous metal obtained by sintering stainless steel and coating the external surface of the member 19 with a semi-permeable membrane 23 formed by electrostatically coating PFA paint. An oil reservoir section 23 and gas reservoir section 21 are respectively constituted on the outside and inside spaces of the member 19 and infrared rays are emitted against a reflecting mirror 26a from a light emitting device 28a. A light receiving device 28b receives the reflected light of the infrared rays from another reflecting mirror 26b on the opposite side of the mirror 26a and the detected of a gas is transmitted to a diagnostic device through an optical cable 17. Since the filter thus constituted has a sufficiently strong mechanical strength, can withstand a remarkably high oil pressure, and well transmits the gas dissolved in oil, the gas can be quickly detected.

Title: Junction for truss
Inventor: MURAKAMI YUKIO
IPC: E04B1/58
Filed: 1995-11-16
Abstract: PROBLEM TO BE SOLVED: To absorb manufacturing-and construction errors and to easily and inexpensively join steel framed trusses by previously welding joining hardwares, in each of which a slit is provided, to the side faces of a pillar and the joining end parts of lattice trusses, and filling spaces engaged with the joining hardwares with mortar. SOLUTION: Joining hardwares 11, in each of which a wider slit than the wall thickness of mating joining hardware is provided in axial direction, are previously welded to both side faces of a pillar 6 and the joining end parts of lattice trusses 7, 8, 9. After the trusses are carried in the field, the joining hardwares 11 are combined with each other, and after completion of temporary assembly of a framework, internal cavities of junctions are packed with cement grout or mortar. Since there is no need for position-alignment of boltholes, some manufacturing error or construction error can be absorbed by the allowance of the junctions. Further, when the joining hardwares 11 are sufficiently long, out-of-plane deformation of the flanges of the pillar 6 can be reduced.  Since there is no need for special brackets or gusset plates, the transport efficiency rises, and since the need for high-tensile bolts can be avoided, the trusses- joining cost can be decreased.

Abstract: PURPOSE:To eliminate the consecutive use of resource relating to the retention continuity in an exchange by detecting it by a detection circuit when a signal representing the disconnection of opposite party is sent from an exchange after retention so as to release the holding state. CONSTITUTION:If the holding of a telephone set is desired due to any reason during talking, a holding switch 55 is closed.
