Abstract: A method of arranging a splice sleeve to receive a reinforcing bar in a mold for use in manufacturing a precast concrete member by providing an elastic body having a through opening hole generally extending through the longitudinal center of the body, in the interior hollow of the sleeve by inserting an extending bar with a pull-out preventing portion at the end of the bar, into the through hole of the elastic body so as to form the bar projecting from the inside of the mold to the outside of the mold, and by drag pulling the projecting extending bar toward the outside of the mold so as to press the elastic body, thereby to fix the elastic body to the interior wall of the sleeve, and the elastic body being compressed so as to get in close contact with the interior surface of the sleeve, thereby to fix the splice sleeve to the mold.

Abstract: In the control of nematodes, use is made of a formulation using D-limonene as a solvent to carry an effective dosage of chloropicrin. The formulation can also include an amount of methyl isothiocyanate corresponding in volume approximately to the amount of chloropicrin. The combination of these two components is synergistic. With the further addition of diazinon, a double synergistic effect is obtained.

Abstract: A conventional pilot lamp which is used in a power plant, substation, or other types of plants, each has its own large and heavy weight transformer below the lamp case. In order to obtain a pilot lamp having the same capacity as the conventional pilot lamp even if the transformer is taken away from the lamp case, the pilot lamp of this invention comprises a lamp, a lamp holder, a heat radiating plate fixed within the lamp holder, an extremely small-sized IC type AC-DC constant voltage regulator connected to the input terminal fixed to the lamp holder, and an output terminal connected to the lamp. Thus, the arrangement contemplated produces a pilot lamp having the same capacity as a conventional pilot lamp, without the large and heavy weight of the transformer unit below the lamp case.

Abstract: A cable connection head is disclosed, in which a well logging cable is inserted through an upper head housing of a head housing consisting of a lower head housing coupled to an upper portion of a measuring instrument housing and the upper head housing coupled to an upper portion of the lower head housing, armoring wires of the well logging cable secured to the upper head housing, and core wires of the well logging cable are connected to a connector which is fittedly secured to the lower head housing. A metal covered cable of the well logging cable is constructed by accommodating a plurality of core wires and filling with an electric insulating material in a metal tube. The lower head housing and metal covered cable are reliably sealed to each other such as to be able to withstand high temperature by inserting the metal tube of the metal covered cable through the lower head housing and securing the metal tube by means of welding around the entire outer periphery to the top of the lower head housing.

Abstract: An improved dome-type structure having a plurality of load bearing rib elements extending upwards from a base and meeting at a common vertex, a roof deck extending over and supported by these rib elements and vertical side panels are all disposed so as to form an enclosure. The improvement comprises using components for forming the roof deck which are generally trapezoidal and rectangular in shape. The structure is assembled with the interconnection of the trapezoidal and rectangular-shaped components with and without structural ribs which are of inverted T-shape in cross-section. A water trap is provided at one or more places around the base of the structure, and, in locations where there is a scarcity of water, an underground reservoir is provided beneath the structure. The arrangement provides protection against earthquakes and earth tremors.The invention also contemplates the transportation of a complete shell unit under its own power by air lift.

Abstract: A thermoelectric thermometer of the radio transmission type incorporating a thermocouple for measuring the temperature of an object having a relatively high temperature, such as metal in a molten state or being heat-treated. A signal representing the temperature measured is transmitted by radio waves and received at a desired location away from the hot object to remotely detect the temperature of the object.

Abstract: A double ranging drum cutter for long wall type machines for coal extraction is disclosed, which comprises a drum cutter body, a television camera mounted on the drum cutter body for picking up an image of a coal layer cutting portion of a lower bedrock being cut by a cutter drum, a television camera mounted on the drum cutter body for picking up an image of a coal layer cutting portion of an upper bedrock being cut by a cutter drum, and a video image processing unit mounted on the drum cutter body and connected to the television cameras, whereby the boundary between a coal layer and bedrock can be readily judged to permit extraction of much coal without cutting much bedrock and also the ratio of the area of a bedrock to the area of a coal layer in a portion of the bedrock being cut can be readily detected.

Abstract: A compound having the formula ##STR1## wherein R.sub.1 represents halogen or methyl;R.sub.2 represents hydrogen or halogen;each of R.sub.3 and R.sub.4 represents halogen; andeach of X and Y represents oxygen or sulfur.The compound is useful as insecticide.

Abstract: Addition compound of fluoran compound and ketone useful as color former for heat or pressure-sensitive color-developable recording material.

Abstract: A winch for an elevator which is provided with a drive pulley rotated through a reduction gear by a motor and a brake unit provided between the motor and the reduction gear, makes it possible to produce the brake unit with a compact frame, light weight and low cost by fixing the frame of the brake unit to a casing of the reduction gear with bolts. Further, it can be assembled. easily for a short period of time. An annular oil keep groove is provided on the casing of the reduction gear. An annular oil interrupting projection disposed in the oil keep groove is provided on a hollow rotary shaft fixed the drive pulley. Therefore, lubricant is securely prevented from leakage from the inside of the casing for a long period of time.
