Abstract: This invention relates to an emergency descending device having a life line, one end of which is adapted to be fixed at a high position, the other end of which is adapted to be extended to a low position, and a descending apparatus movably affixed around the life line and usually kept at a high position before operation. The descending apparatus is adapted to suspend a person and carries the person along the life line at a low speed from a high position to a low position. The improvement is characterized by the descending apparatus comprising a decelerating element which is a tubular member axially passed by the life line, forming a contact surface within the tubular member, and in addition, the contact surface being corrugated so as to increase the friction between the contact surface and the life line and reduce the descending speed of the descending apparatus while it suspends a person and lowers him/her from the high position.

Abstract: Nitrogen-containing 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide derivatives are prepared by condensation of the oxide with amines and aldehydes or ketones. They may be used as additive flame retardants or incorporated into synthetic resins such as polyesters and polyurethane foams, by copolymerization to form flame-retardant resins. They may also be used as antioxidants, germicides or herbicides.

Abstract: A projection exposure apparatus of the type which employs an alignment light of the same wavelength as an exposure light and includes an optical system subjected to correction of chromatic aberration for the exposure light so as to simultaneously observe an alignment area on a reticle and an alignment area on a photosensitive substrate to bring the reticle and the photosensitive substrate into alignment. The apparatus includes light source means for emitting light of a wavelength different from that of the exposure light and capable of sensitizing the photosensitive substrate, and optical means for introducing the light source means into the optical system to project it on to the alignment area on the photosensitive substrate through the alignment area on the reticle.

Abstract: The present invention provides a method for assaying a biocomponent on the basis of an amount of bound peroxidase by the steps of supporting a biocomponent or a target substance containing a biocomponent on a gel-like carrier, developing the biocomponent or the target substance by electrophoresis, binding a receptor to the biocomponent or the target substance, binding peroxidase to the receptor, and determining the amount of the bound peroxidase, wherein hydrogen peroxide and 4-methoxy-1-naphthol are used as substrates.

Abstract: A method and apparatus for the precision measurement of positions, dimensions, etc., of a pattern or mark formed on the surface of a flat object such as a photographic mask or reticle. The amount of vertical deviation of the object with respect to a reference plane is detected at each of a plurality of measuring points and the incline of the surface of the object with respect to the reference plane at each of the measuring points is determined in accordance with the amounts of deviation and the distance between the measuring points. The coordinate positions of each of the measuring points in the reference plane are measured in accordance with the amount of movement of the object parallel to the reference plane and the coordinate positions are corrected in accordance with the corresponding incline.

Abstract: A plug, such as a vent plug for mounting in a hole in the wall of a machine element, e.g. the end wall of the rotor casing of a pump comprising a canned motor, comprising an outer cup provided with a support flange and an inner cup pressed into the outer cup and comprising a locking device. The locking device is preferably formed as a locking flange, e.g. in the form of part of a thread serving to interlock the plug and the wall. The distance between the locking device and a sealing face of the support flange or of a sealing element connected to the support flange is smaller than the axial displacement of the plug in connection with the engagement of the locking device with the wall.

Abstract: An input apparatus for entering base sequence information of the gene, comprises a computer for analyzing the base sequence of the gene, an input apparatus for entering base sequence information of the gene to the computer which successively stores the base sequence information entered by the input apparatus and produces the stored base sequence information, and a speech sounding apparatus supplied with the base sequence information produced from the computer for sounding speech corresponding to the base sequence information produced from the computer.

Abstract: Rock salt solution contained in the salt cavern is pumped out, after which particulate solid waste materials are treated with dust suppressant agents to form free-flowing, non-dusting, readily usable mixtures, which are introduced into the cavern by trickling, or the salt cavern filled with rock salt solution is filled with a pumpable mixture of solid and liquid waste materials in such a way that the displaced volume of salt solution is pumped out and, after filling the cavern to about two thirds to three quarters of its volume, the water of the liquid phase is bound in the form of water of crystallization or as hydroxide or physically by adsorption through addition of hydrophilic compounds or substances as a means of solidifying it, and the cavern is then sealed.

Abstract: A photographing and recording method and apparatus for an electronic still picture camera of the type in which an image is picked up by a combination of a mechanical or electrooptical shutter and an image pickup device and the resulting picture signal is recorded on a magnetic disk, eliminate any undesired power consumption due to the preliminary revolution of the magnetic disk. The revolution of the magnetic disk is started upon the depression of the shutter button and the revolution is controlled at a constant speed by a velocity servosystem.

Abstract: Scissors for cutting a V shape have two parts which are pivotably coupled. The first part has a V-shaped cutting block with two cutting edges which meet at an apex. The second part has a pair of cutting blades with cutting edges which cooperate with the cutting edges of the cutting block during relative rotation of the parts. The cutting blades are arranged such that the point at which the cutting edges of the cutting block meet engages the cutting edges of the cutting blades at different angles in the relative rotation of the two parts.
