Rings 3 having almost the same diameter as the rubber block 1 and consisting of a plurality of metals of iron, copper, or the like and strand wire thereof or carbon fiber, etc., are wound along the outer periphery of the rubber block 1. Then, a base isolation device is interposed between, e.g. the foundation and lowermost stair of a building and so forth. At this time, the rubber block 1 tends to run out sideward by the vertical loads of the post; however, its shape is retained by the restraining member 3. Thus, the rubber block 1 can be restrained from sinking during the period of execution or use.

Abstract: PURPOSE:To make cell thickness and response speed uniform to suppress generation of Newton's rings and to make the range of a visual angle wider and the thickness smaller by constituting a liquid crystal display body of the substrates formed with members having different numbers of layers and different coeffts. of expansion into one body. CONSTITUTION:A device is constituted of the 1st-3rd electrode substrates 1, 7, 2. An upper plastic film 12 of the substrate 1 sandwiching a polarizing film 11 has the coefft. of expansion larger than the coefft. of expansion of a lower film 13 and therefore when said substrate is adhered to a substrate 7 by an adhesive layer 4 at a high temp. and is allowed to cool to a room temp., the outside thereof is going to curve on the side opposite from a liquid crystal layer 6 but since the substrate 7 is glass and is hardly curved by an environmental change, the substrate 1 is maintained by spacers 5 and is thus prevented from deforming. The substrate 2 has a polarizing film 21 and a reflecting film 25 between plastic films 22 and 23 and the substrate 2 is held by means of the substrate 7, the spacers 5, etc. in the same way as with the substrate 1 and therefore the laminated two layers 6 are made respectively uniform.

Abstract: PURPOSE:To improve mechanical strength and heat resistance and to obtain the high orientability for a liquid crystal by using a Langmuir-Blodgett film (LB film) formed by using a specific high-polymer liquid crystal having mesogen contg. a pyrimidine ring in its side chain as the oriented film. CONSTITUTION:The high-polymer liquid crystal which has the mesogen contg. the pyrimidine ring in its side chain and is expressed by formula I is used as the blank material for the LB film. Further, this blank material for the LB film is used as the liquid crystal oriented film, by which the production of the liquid crystal element of large area is enabled. In the formula I, R denotes a methyl group or hydrogen atom; n denotes 10 to 20 degree of polymn.; K denotes 3 to 10 and m 3 to 12 which are respectively the integers to denote the number of carbon atoms of the methylene group. A hydrophilic part and hydrophobic part are required to exist with proper balance within the molecule in order for the blank material to form the LB film and such film formation is enabled by synthesizing the high-polymer liquid crystal having the mesogen of the type of formula II as the side chain. Strains remain in the mesogen part in the as-laminated state of this LB film and, therefore, the film is once heated up and is cooled after melting.

Title: Drop-out compensating circuit of disk reproducer
Inventor: TSUJIMURA SATOSHI
IPC: G11B7/095
Filed: 1984-04-03
Abstract: PURPOSE:To prevent easily the generation of a fault such as a track jump, etc. by using a secondary detection means for data, a deciding means to output a drop-out detection signal and a level control means which continues actuation until a data detecting means passes through a position where a drop-out is detected by the secondary detection means. CONSTITUTION:The output levels of photodetection parts PD3 and PD2 are successively attenuated or increased when a main beam spot BS1 and secondary beam spots BS2 and BS3 reach an injured area on a disk. Thus the output of an arithmetic circuit 18 which adds the outputs of both parts PD2 and PD3 is supplied to a comparator 20. The comparator 20 outputs a drop-out detecting signal of an H level when the output level of an envelope wave detecting circuit 19 is lowered less than the reference voltage V. As a result, an attenuating circuit 14 is driven to reduce the level of a tracking error signal. This prevents an undesired track jump.
