Abstract: An object of the present invention is to provide a highly integrated infrared detecting element array having infrared detecting elements which are disposed at a high density and have a low heat capacity each. An insulator film 2 is provided on a silicon substrate 1 having upper surface in a {100} plane; opening portions are defined by etching right-angled triangular portions defined at four corners of each of right-angled quadrilaterals arranged in matrix array and enclosed by two orthogonally crossing pairs of parallel linear portions extending on the insulator film a pyramid cavity; 3 is defined into the silicon substrate underlying the insulator film 2 by anisotropically etching the silicon substrate; and infrared detecting elements are formed on the insulator film 2.

Abstract: A thermal-type infrared detecting element is provided which includes an infrared detecting member, a support member supporting the infrared detecting member, a substrate holding the support member, and a low thermal conduction part intervening between the substrate and a central portion of the support member, the support member having a link portion in at least a peripheral portion thereof which links the support member to the substrate and slits and/or grooves defined at a location adjacent the link portion. This infrared detecting element exhibits excellent sensitivity and responsiveness while requiring no cooling, and a one- or two-dimensional array of the element assures clear imaging with less crosstalk.

Abstract: An apparatus for the application of wrapped articles to package containers which includes a transferring and sealing device by means which articles are transferred and sealed to the surface of a package container which is carried in a bucket wheel. The apparatus is further characterized in that the bucket wheel is provided with an odd number of compartments and the pitch between packages on a conveyor supplying packages to the bucket wheels is twice the pitch of the compartments on the bucket wheel. In addition, the transferring and sealing device inclines the articles so that they are obliquely adhered to the package containers.

Abstract: An arc resistant insulator composed of a composite composition comprising an insulating base material and a zinc borate hydrate. The insulating base material is composed of aluminum oxide and/or aluminum hydroxide and mica power. The zinc borate hydrate is composed essentially of 2ZnO.3B.sub.2 O.sub.3.3H.sub.2 O. The arc resistant insulator is prepared by mixing the insulating base material with a zinc borate hydrate forming material composed of normal boric acid, boric acid anhydride and zinc oxide and heating and compacting the mixture thus obtained in a closed system at a temperature of at least 155.degree. C. under pressure of at least 50 kg/cm.sup.2.

Abstract: A cam operated gripper driven by an endless chain receives at a feed station a wrapped straw having a heat-bondable portion and carries the straw to a bonding section. The gripper is associated with an electric heater which is in contact with the gripped straw. In the bonding section, an electric power supply rail is provided so that a collector of the heater slides on the rail, energizing the electric heater to heat the heat-bondable portion of the wrapped straw. In the bonding section, the heater is also pressed against the carton travelling in a production line at the same speed as the moving speed of the heater with the heat-bondable portion of the wrapped film therebetween. Thus one film wrapper is heat-bonded to each carton. After the completion of bonding, the cam operated gripper releases the straw allowing the straw to remain attached on the carton.

Abstract: A common intermittent drive mechanism intermittently rotates a feed roller and a cutter rotor. An intervening gear and the radii of the feed roller and the cutter rotor differentiate the circumferential speed of the roller and the rotor to provide a slip between a continuous strip-like dispenser sheet fed by the feed roller and the cutter rotor surface. A suction means in the cutter rotor surface holds the dispenser sheet while allowing the slip thereof. When the movement of the cutter rotor is interrupted, a cutter is actuated and separates the individual articles from the remaining dispenser sheet. While the separated article is carried by the moving surface of the cutter rotor for a distance greater than the pitch of the article wrapped in the dispenser sheet, another single article is moved into the position for separation, and this procedure is repeated.

Abstract: A device for tightly wrapping objects is provided which includes suction boxes for holding the wrapping paper under tension as it is wrapped around the object. The holding of the wrapping paper using suction boxes permits the paper to be tightly tensioned around the object regardless of the smoothness of the surface of the wrapping paper. The wrapping paper is folded across the bottom of the object by cooperation between a plate means positioned under the object and the movement of holding means which holds the object.
