Disclosed herein a technique for producing a gas mixture for controlling an oxygen concentration in the interior of a container while reducing the overall weight of the apparatus. For this purpose, a gas mixture supply device is provided for a container refrigeration apparatus. The gas mixture supply device is provided with adsorption columns. If one of the first and second adsorption columns is supplied with air, the adsorption columns are pressurized, and nitrogen in the air is adsorbed onto an adsorbent. If air is sucked from the other of the first and second adsorption columns, the adsorption columns are depressurized, and nitrogen adsorbed onto the adsorbent is desorbed. A gas mixture including the nitrogen desorbed from the adsorbent is supplied to the interior of a container.

Refrigeration unit for container

An oxygen concentration in the interior of a container is detected by an oxygen concentration detection sensor. If the oxygen concentration detected by the oxygen concentration detection sensor is higher than that of a gas mixture, the container is supplied with the gas mixture having an oxygen concentration lower than that of the outside air and higher than a target concentration. The oxygen concentration in the interior of the container is reduced to the vicinity of the oxygen concentration of the gas mixture by supplying the interior of the container with the gas mixture, and then is further reduced to the target concentration by respiration of plants. This appropriately controls the oxygen concentration in the interior of the container, and reduces a decrease in the degree of freshness of the plants.

A cutter including a blade member () having an edge portion () for cutting a current-carrying member () and an insulating portion (); a gas generator () that generates high-pressure gas to move the blade member () toward the current-carrying member (); a receiving member () arranged on a side opposite to the edge portion () relative to the current-carrying member () and defining a receiving surface () for receiving the current-carrying member () upon cutting thereof; a stopper () configured to restrict forward movement of the blade member () such that the insulating portion () of the blade member () stops, after cutting of the current-carrying member (), at a position corresponding to a cut surface of the current-carrying member (); and an insulating protective member () positioned between at least one of the blade member () or the receiving member () and the current-carrying member () and configured to protect a surface of the current-carrying member () facing the at least one of the blade member () or the first inner cylinder member () are provided.

A reciprocating pump includes a motor having a motor shaft, four cylinders, four pistons disposed in the cylinders and reciprocated by the motor shaft, a casing accommodating the motor shaft, and eight ducts. The four cylinders are disposed at positions offset 90 degrees from each other about the motor shaft. Cylinder shaft directions are perpendicular to a motor shaft direction. The eight ducts include four intake ducts and four exhaust ducts. Gas is introduced into the cylinders through the intake ducts and discharged from the cylinders through the exhaust ducts. The eight ducts are disposed in a region surrounded by the cylinders when viewed along the motor shaft direction. The eight ducts are arranged in four pairs with each pair disposed between adjacent cylinders about the motor shaft. The four pairs of ducts disposed between the adjacent cylinders extend along the motor shaft direction.

A cutter includes a stopper with which a blade after cutting a harness with a cutting portion collides and stops. The blade includes a flexible guide portion which protrudes further in a forward direction of the blade than the cutting portion.

Cutter

A blade (), which includes a cutting portion () and an insulating portion (), is used as a blade () of a cutting apparatus (). The cutting portion () is made of a metal, and has a blade portion. The insulating portion () is formed by an insulating member, and forms a part that adjoins the blade portion in a direction opposite to an advance direction of the blade (). The cutting apparatus () is configured so that, when cutting a current-carrying member (), the blade () advances until the insulating portion () contacts cut faces of the current-carrying member () after the cutting portion () cuts the current-carrying member ().

Cutting apparatus, breaker, contactor, and electrical circuit breaker

Disclosed is a gas pressure actuator whose actuator body has a cylinder, a piston and a gas generator in which a powder is loaded, and the gas generator is positioned at an end portion of the cylinder. The gas generator injects a high pressure gas into the cylinder by the combustion of the powder, thereby moving the piston. The actuator body is provided with a coating which covers the entire actuator body from outside. The coating is a resin coating having electrically insulating, waterproof, and dustproof characteristics.
