Abstract: The gas measurement device includes a filter unit including a plurality of terminals configured to be applied a voltage or a current and a filter configured to vibrate in response to the voltage or the current being applied to the plurality of terminals and a gas sensor configured to detect gas molecules passing through the filter and output a measurement value corresponding to the detected gas molecules.

Abstract: A stator includes a first teeth unit including a first insulator having an annular first crossover wire guide and a plurality of first winding units radially provided at regular intervals on an outer circumference of the first crossover wire guide to cover teeth of one phase group of an alternating current, the teeth of the one phase group having upper halves fitted to the first winding units, a third insulator that covers lower halves of the teeth, and a winding wire of one phase wound around the teeth of the one phase group, a second teeth unit having an identical configuration to that of the first teeth unit in which a winding wire of the other phase is wound in a concentrated manner, with second winding units inserted between adjacent ones of the first winding units, and an annular yoke including a plurality of recesses at regular intervals.

Abstract: It is an object of the present invention to provide a mold clamping mechanism and an injection-molding machine that use a structure eliminating a die plate for clamping a mold to realize a compact structure and can shorten a molding cycle of a resin molded product by carrying out a mold clamping operation and an operation for releasing the mold clamping operation at higher speed.

Abstract: A second metal mold 15 has a through hole 31 that extends in the movement direction of the second metal mold 15. A first metal mold 14 has an internal threaded portion 34 that extends on a common line with the through hole 31 and has an opening at the surface of the first metal mold 14 facing the second metal mold 15. A bolt 39 formed by a shaft 37 and a head 38 is employed. The shaft 37 is passed through the through hole 31 in such a manner that the head 38 is arranged at the opposite side to the first metal mold 14 with respect to the second metal mold 15, and the distal end of the shaft 37 is located at the same side as the first metal mold 14 with respect to the second metal mold 15. When the second metal mold 15 is held in contact with the first metal mold 14, the bolt 39 is rotated by an electric motor 45 through the head 38. In this manner, an external thread 41, which is formed at the distal end of the shaft 37, is threaded to the internal threads 36 of the internal threaded portion 34.
