Abstract: The present invention provides alginic acid derivatives represented by formula (1) and formula (II), and a novel crosslinked alginic acid obtained by carrying out a Huisgen reaction using an alginic acid derivative of formula (1) and an alginic acid derivative of formula (II). There are thereby provided novel alginic acid derivatives and a novel crosslinked alginic acid.

Abstract: There has been demand for an additional method for producing antibodies. The present invention provides: a polymer-coated crosslinked alginate gel fiber in which a core layer containing a crosslinked alginate gel and either antibody-producing cells (e.g., antibody-producing CHO cells) or bioactive-substance-producing cells (e.g., MIN6 cells derived from pancreatic ? cells) is coated with a cationic polymer; and a method for producing antibodies, a bioactive substance, etc., using the fiber.

Abstract: A hydraulic pressure control device includes a cylindrical valve body, at least one opening portion provided on the valve body, a spool valve disposed in the valve body and slidable along an inner surface of the valve body, at least one land portion provided at the spool valve and slidable along the inner surface of the valve body, and at least one recess provided at land portion of the spool valve wherein opening width of the recess continuously changes in sliding direction of the spool valve.

Abstract: A torque-detecting device includes a first member rotatable with a drive shaft of an engine generating torque; a second member rotatable in an identical rotational direction to one of the first member; an elastic member positioned between the first member and the second member, an elastic member which is elastically deformed in a rotational direction at a radially predetermined position between the first member and the second member so as to transmit torque, and so as to absorb torque vibrations that occur between the first member and the second member; a detecting unit for detecting a degree of load applied to the elastic member; and a calculating unit for calculating, on the basis of the degree of load detected by the detecting unit, a degree of torque transmitted from the first member to the second member.

Abstract: A linear solenoid valve provided in a hydraulic pressure control device includes a cylinder having a inlet port communicating with the controlled element and a drain port communicating with a drain, a permanent magnet having a first magnetic pole and a second magnetic pole surrounding the first magnetic pole, a wound movable coil located between the first magnetic pole and the second magnetic pole and movable to the axial direction of the permanent magnet, a valve body disposed with respect to the movable coil to selectively permit and prevent communication between the inlet port and drain port to control communication between the controlled element and the drain. The hydraulic pressure applied to the controlled element is controlled based on an electromagnetic force of the movable coil resulting from electric current applied to the movable coil and a magnetic field generated between the first magnetic pole and the second magnetic pole.

Abstract: Disclosed is an electrolyte for an electrolytic capacitor which comprises a salt of a tertiary dicarboxylic acid represented by the following formula (I) or (II): ##STR1## wherein n represents an integer of 1 to 5, and R.sup.1 to R.sup.4 each represents an alkyl group having 4 or less carbon atoms, ##STR2## wherein n has the same meaning as defined above, l and m each represents an integer of 4 or 5, and R.sup.5 and R.sup.6 each represents hydrogen atom, methyl group or ethyl group,and an electrolytic capacitor using the same.

Abstract: A ultrasonically diagnostic apparatus including a ultrasonically diagnostic body for obtaining ultrasonic information, in which an operational table arranged in front of the body is rotatably supported by a pivotally supporting device which is slidably supported by a slidably supporting device secured to a front side of the body, and thus the operational table is pivotal in left and right hand side directions and also slidable frontwards and rearwards.
