Abstract: PURPOSE:The titled microspheres of a high strength, a high modulus and a high water content, obtained by freezing an aqueous PVA solution in the form of water drops dispersed in a specified dispersing medium and crystallizing the polymer at a low temperature. CONSTITUTION:An aqueous PVA solution kept in the form of water drops is obtained by pouring an aqueous solution containing 5-40wt% PVA of a degree of saponification >=95mol% and an average degree of polymerization >=1,000 into a dispersing medium such as a water-immiscible organic solvent (e.g., benzene) or an oil (e.g., silicone oil) with agitation at a speed of 200rpm. This aqueous PVA solution is frozen by cooling to -5 deg.C or below for at least 5hr, and the polymer phase of PVA is isolated to obtain a frozen-phase molecular structure. This structure is left standing at 0-10 deg.C for at least 10hr to crystallize the polymer phase. In this way, high-strength, high-water content, porous PVA gel microspheres of a diameter of 0.1mum-1mm, a pore diameter of 0.01-50mum, a water content of 40-95wt% and a compressive strength >=10kg/cm<2> are obtained.

Title: Semiconductor circuit
Inventor: TOKUMITSU TSUNEO
IPC: H03H7/38
Filed: 1984-09-07
Abstract: PURPOSE:To enable the enlargement of bands by improving the reproducibility of the monolithic microwave integrated circuit (MMIC) by a method wherein the effects of capacitance shift are cancelled by using the correlation between capacitors of the same kind mounted on the MMIC. CONSTITUTION:In the MMIC, an impedance matching circuit is made of distributed constant lines 6', 8, 9, and 10, capacitors 7 and 11, an inductor 12, etc. in order to match impedances between a power source impedance 5, etc. and an active element 1, etc. At this time, when the capacitances Ca and Cb of the capacitors 7 and 11 vary at the same proportion, the variations are cancelled with each other, thus determining circuit constants so as to keep matching in reference points A-A'. Since the MMIC has correlation in the shift from the design value of the capacitance, the matching condition is kept even under the variation in capacitance of the capacitors 7 and 11, resulting in the improvement of reproducibility. Besides, it is possible to apply concentrated constant capacitors; therefore, the matching circuit can be enlarged in band.

IPC: B66B11/00
Filed: 1994-08-09
Abstract: PURPOSE:To improve services for a user and shorten a work time by eliminating the need of stopping an elevator and entering a pit at the time of inspection. CONSTITUTION:When an elevator ascends from a reference floor near the lowest floor, a detector 10 detects a detection piece 9 fitted to a balance weight 4 at a position near an intermediate floor. Also, a position operation device 11 always knows the position of an elevator car, according to pulse signals from an encoder and, therefore, can find a car travel distance from the ascent start position of a car 1 to the level where the piece 9 is detected. In this case, the distance varies, due to the elongation and contraction of a main rope 3. On the contrary, therefore, the elongation and contraction of the rope 3 can be found from the variation of the distance, and the device 11 can find the position of the weight 4. When the position of the weight 4 is abnormal, an output device reports the error of the weight 4 by means of a sound, light or the like.
