A stop member support device has one end affixed to the base, and at the other end is a stop member support portion.

Abstract: This invention provides a method for recovering nucleic acids and a device for the same purpose, which method and device are capable of continuously recovering nucleic acids by enabling the recovery of nucleic acids in one simple operation. This nucleic acid recovering device comprises: a container to which a solution containing micro-organisms is supplied; electrodes which are made of a hollow fiber membrane coated with a conductive metal and which send electricity to the solution; a pulse oscillator which sends pulse waves to the electrodes; and a micropump which draws up the solution within the hollow fiber membrane coated with metal.

Abstract: The present invention provides a widely applicable electric component holder and a mechanism for securing this electric component holder. It enables attachment of an electric component to a receiving member without protruding on the back face of the receiving member and which allows simple attachment to and detachment from the receiving member. This electric component holder includes a holding portion for holding an electric component and a securing portion for securing this holding portion on the receiving member, and this securing portion includes engaging claws 40, 42 and 44 which are inserted into a hole opened into one face of the receiving member in a parallel direction to the receiving member face, in a direction parallel to the receiving member face, thereby engaging releasably with the installation portion.

Abstract: The collapsible housing frame has a pair of side frame boards opposed to each other, and connecting mechanisms which connect both the opposed ends of the side frame boards. Both ends of the side frame boards are connected to the connecting mechanisms through first hinges. Each of the connecting mechanisms is formed to be collapsible at a second hinge of the connecting mechanism, and a lock-unlock system to lock and unlock the hinge is provided at the second hinge.

Abstract: A porous hollow fiber membrane is dipped into either a high concentration alkali solution or a high concentration solution of chromic acid and sulfuric acid, etched and then dipped into a palladium ion solution. The membrane is then dipped into a solution containing reducing and complexing agents as well as metallic ions, and subjected to an electroless treatment. In this way, a porous hollow fiber membrane, to which a metallic layer is chemically bonded, can be obtained. The porous hollow fiber membrane is provided in which the bond strength between the membrane and the metallic layer and the amount of metal to be coated are increased. Because of a large amount of metal, it is possible to render the membrane sufficiently electrically conductive.

Abstract: A signal discriminator which comprises a plurality of divided magnetic cores which surround a peripheral part of a cable when the plurality of divided magnetic cores are integrated. A resin case formed of a plurality of sections is capable of opening and closing and accommodates the plurality of divided magnetic cores. A press-contacting device press-contacts at least one of the plurality of divided magnetic cores and a corresponding one of the plurality of sections of the resin case. Engaging protrusions on the plurality of divided magnetic cores engage with corresponding recesses on the plurality of sections of the resin case.

Abstract: Frame structure for housing panel plates such as printed circuit boards. This structure is capable of housing panel plates having varying width, and consists of a top plate that is spaced from a bottom plate fixed thereto by means of support columns. The structure also has an immovable side board and a movable side board between the top and bottom plates. Each of the opposing side boards has a plurality of lateral grooves for housing the plates. The movable side board is easily movable while it is kept parallel to the immovable side board.

Abstract: A circuit test clip with a plurality of conducting elements making simultaneous electrical contact with an equal number of terminals on a miniaturized circuit formed on a printed circuit board. The test clip is useful for inspection or otherwise testing such miniaturized circuits.

Abstract: A cable holder for securing a cable airtightly comprises a mounting body with a hollow cylinder for receiving the cable, a clamping cap to be threaded with the thread on the outer periphery of the mounting body and having an opening on each end in its axial direction and frustoconical gripper assembly to be inserted between the cylinder and the clamping cap. The gripper assembly is formed in a shape of a iris diaphragm of a camera and each of the diaphragms is movable and capable of shorting its inner circular diameter defined by the diaphragms for gripping the cable.

Abstract: Device for locking a panel plate to a housing and releasing it therefrom is comprised a saddle body including a saddle seat and a pair of parallel leg plates extending therefrom. Each of the leg plates has an aperture bored at a portion remote from the seat, and a pin which is made integral with one leg plate by means of a plurality of thin film strips extends outwardly from the periphery of the aperture in that plate in a direction normal thereto. After positioning the panel plate between the leg plates and bringing the apertures in the leg plates into alignment with the aperture bored in the corner of front side of the panel plate, the pin is driven into the apertures, whereupon the device is pivotally attached to the panel plate.

Abstract: A binding device of the invention comprises a base plate and a flexible ladder-like belt. The ladder-like belt has a plurality of parallel rungs between a pair of side rails and is pivotally mounted on one end of the plate. The other end of the plate is provided with a stopper for engaging one of the rungs to bind a bundle of cable or the like.

Abstract: A cable holder being attachable through a hole of a box plate of a panel board box, using a mounting body into which an insertable resilient member can be slid. The insertable member also is provided with an axial through hole in which a cable is inserted. The insertable member, holding the cable through the hole, is inserted into the hollow cylinder of the body and clamped around the body to thereby hold the cable in the cable holder.
