Abstract: A lubricating agent obtained by mixing a polyether compound and cyclic polyorganosiloxane of a specified type at a specified ratio is applied at a specified ratio to synthetic yarns which are to be subjected to a heat treatment process such that heater deposits can be eliminated.

Abstract: A rectangular semiconductor chip is bonded onto a rectangular island at the center of a frame having a plurality of inner leads extending radially from the center. The chip has a plurality of pads adapted to be connected by wire bonding to corresponding ones of the inner leads. The pads are disposed sequentially along at least one side of the rectangular chip. Separations between mutually adjacent pairs of these pads along the side of the chip are smaller in the center part than in the end parts of the side such that the pads can be disposed closer together while preventing interference between mutually adjacent pairs of the bonding wires.

Abstract: A sample containing nucleic acid molecules is mixed with a same volume of reagent such as isopropanol to render the nucleic acid molecules insoluble. This solution containing the nucleic acid molecules in insoluble condition is introduced into a flow cell and exposed therein to light from a light source. Scattered light from the nucleic acid molecules is detected by light sensors and analyzed by a computer.

Abstract: A data conversion circuit has an input terminal for receiving serial data as time-divided multiple signals, a plurality of sample-and-hold circuits each connected to the input terminal, and output terminals each connected to an associated one of these sample-and-hold circuits to output the received signals as parallel data.

Abstract: A bag maker bends an elongated flexible bag-making film into a tubular form and transversely seals it by a transverse sealer while filling it with articles to produce packaged bags. The transverse sealer has two seal jaws at both sides of the film being pulled downwards. The seal jaws are each caused to move in a generally D-shaped trajectory with a vertically straight portion where they move along the film, sandwiching it therebetween. The seal jaws are operated so as to move faster than the film while on the top half of the straight portion of the trajectory where stripping takes place and more slowly than the film while on the bottom half of the straight portion such that the film will blouse to make it easier for articles to drop deeper inside the bag being produced. The speed of each seal jaw on the arcuate part of its trajectory is adjusted such that the period of the cyclic motion of the seal jaws need not be modified.

Abstract: A combinational weigher measures articles with a plurality of measuring devices and selects a combination of the articles with a total weight within an allowable range. The weigher has a device for supplying the articles, cameras for taking pictures of at least either this article supplying device or the articles thereon, an image processing device for determining the condition of the article supply on the basis of image signals from the cameras, a predicting device for predicting the change in the amount of the supplied articles on the basis at least of the condition thus determined, and a control device for changing the operating conditions of the supplying device on the basis of this prediction so as to control changes in the supply rates of articles to the measuring devices.

Abstract: Photocurable resins containing unsaturated urethane of a specified form and vinyl monomer which is N-(meth)acryloylmorpholine or its mixture with di-ol di(meth)acrylate at a rate within a specified range and compositions containing such a resin and a filler such as solid particles and/or inorganic whiskers of specified kinds at a specified rate are capable of yielding stereo lithographed objects with improved mechanical and thermal properties and form precision.

Abstract: A liquid vaporizer-feeder has a unitary housing structure for both a control valve for controlling the amount of a liquid passing therethrough and a vaporization valve for causing the liquid from the control valve to be vaporized and transported out by a carrier gas. The housing structure has a throughhole through which the two valves are connected. The throughhole is short and narrow, and has a portion made even narrower such that the pressure in the liquid passing therethrough is increased, preventing bubbles from forming in the throughhole. As a result, vaporized liquid can be supplied at a steadier rate, for example, to a reaction chamber.

Abstract: Fixed amounts of a liquid source for a chemical vapor deposition process is supplied continuously from a source tank and through a liquid mass flow controller to a three-way valve. Inside the three-way valve, the liquid source is evaporated to generate a source gas by contacting a high-temperature carrier gas which flows therethrough and becomes mixed with the source gas. The gas mixture thus generated is supplied into a process chamber for a chemical vapor deposition process. The carrier gas may be heated by a gas heater before entering the three-way valve. Alternatively, the three-way valve may be enclosed inside a thermostatic container, the carrier gas being heated inside the container.

Abstract: After a heated object such as a processed wafer is placed inside a load lock chamber in a vacuum condition, a specified limited amount of vent gas is introduced and the pressure inside the chamber is maintained at an intermediate level for a specified length of time so a to control its thermal gradient. After the specified length of time, the chamber is completely vented. Both software and hardware implementations are possible for this staged vent.

Abstract: An apparatus for measuring the temperature of a wafer by a non-contact method includes a supporting device, at a specified position on which the wafer is placed horizontally. A thermocouple is provided with a heat collector at one end thereof. The heat collector is disposed near but in non-contacting relationship with the wafer at the specified position. A reflector capable of reflecting radiant heat is disposed near the heat collector and on the opposite side thereof from the wafer such that radiant heat from the wafer can be efficiently collected by the heat collector.

Abstract: An electron collimation system for electron arc therapy treatments consists of a slit collimation system which is movable with the electron beam applicator and is designed to allow for dose compensation in the sagittal direction and a hoop-and-clamp assembly for final field shaping. By correctly designing the shape of the slit in the former and properly adjusting the components of the latter, it is possible to accomplish quite uniform shielding without causing any weight of the shielding material to rest on the patient.

Abstract: A liquid sample in a syringe can be injected into a capillary column with inner diameter less than 200 microns without inserting the injection needle of the syringe into the column. The end of a modified injection needle according to this invention has a tubular opening with inner diameter sufficiently large so that the intake end of the column can be inserted inside, thereby establishing an annular duct between the needle and the column. A carrier gas is caused to flow through this duct while the plunger on the syringe is pressed to squeeze the liquid into the needle, thus forcing the liquid into the capillary column.

Abstract: In operating an ECD in constant current mode, two pulses are implemented either to the same electrode or to separate electrodes, thereby dispersing the space charge sheath near the collector electrode and thus enhancing electron extraction at high frequencies. This has the effect of extending both the dynamic range and the linear dynamic range.

Abstract: A hydraulic pulse dampener has two diaphragms, each positioned opposite a recess formed in the housing. The regions between the diaphragms and the associated recesses are sealed from the fluid which flows through the dampener so that a rise in pressure in the fluid may cause each diaphragm to flex towards the recess behind until it may completely nest in it. The diaphragms are designed differently so that they will begin to flex and take a completely nested position in different pressure ranges.

Abstract: The contrast ratio of an image intensifier of the photocathode-amplifier-phosphor type is increased by using a fiber optic plate of which the thickness is reduced to such extent that the plate may not be able to function as a vacuum seal or an electrical insulator when a typical voltage for the operation of the intensifier is applied to the phosphor layer. This relatively thin fiber optic plate is placed entirely inside a vacuum, protected from the atmospheric pressure by a thick output window plate which is optically transparent.

Abstract: A hydraulic pulse dampener of liquid compressibility type has a flexible tubing wound around a form within a liquid-tight housing filled with a compressibility liquid and a stiff diaphragm placed adjacent a recess formed in a receiving member. As the fluid flowing inside the tubing experiences pressure pulses, the walls of the tubing expand and transmit the pulse energy through the compressibility liquid and causes the diaphragm to gradually flex towards the recess until it may completely nest in it. The recess in the receiving member preferably has a central flat portion so that the flexing diaphragm will first contact the receiving member at the center and the nesting will spread outwardly therefrom.
