An elevator according to an aspect of the present invention includes a car speed detection device that measures car speed, an emergency braking device that comes into press contact with a guiderail and emergently stops a car when the car speed exceeds a threshold, an electric actuating unit that electrically actuates the emergency braking device, a battery that supplies electric power when commercial power supply is interrupted, and a safety control unit that monitors abnormality of the elevator and controls operation of the electric actuating unit. The safety control unit measures remaining power of the battery when the electric power is supplied from the battery, determines operation propriety of the emergency braking device at commercial power supply restoration time based on transition of battery remaining power, and controls operation of the electric actuating unit at the commercial power supply restoration time based on content of the determination.

Elevator and control method for elevator

Provided is a technique to identify a sample substance attached to an inspection target easily and precisely, while improving the rate of operation and reducing the number of persons required for inspection. A trace detecting system includes detection means to detect the size (vertical and horizontal dimensions) of an inspection target, and selects an air nozzle capable of spraying air jet at 15 m/s or more to the surface of the inspection target for air jet spraying.

Attached matter testing device and testing method

Provided is an analyzer for a substance, including: a first particle holding unit having a tubular shape; a first intake pipe for sucking a gas from an upper side of the first particle holding unit to cause a cyclonic phenomenon inside the first particle holding unit; a first supply pipe for supplying a sample containing particles, the first supply pipe being connected to a side surface of the first particle holding unit; a first flow control unit for controlling a flow rate of a gas flowing into the first particle holding unit to hold the rotationally moving particles inside the first particle holding unit for a predetermined time period and then cause the particles to settle, the first flow control unit being connected to a lower part of the first particle holding unit; a first collection heating unit for collecting and heating the settled particles; and an analysis unit for analyzing a substance vaporized from the particles through the heating by the first collection heating unit, the analysis unit being connected to the first collection heating unit through a pipe.

Analyzer for substance

Sample fine particles attached to an inspection object are identified simply and with high accuracy, and an increase in operation rate and a decrease in device size are achieved. The inspection object is transported into a sampling chamber defined by a pair of side walls and an upper wall enclosing a part of a transport route of a transport unit. The inspection object is sprayed with compressed gas from an air nozzle, the peeled sample fine particles are aspirated into a collector, and the sample fine particles are separated from the aspirated gas for analysis. The air nozzle is disposed on one of the side walls defining the sampling chamber. The collector is disposed under the other side wall as a container independent from the sampling chamber.

Attached matter inspection device

Provided is a technique of analyzing particles in real time while collecting and condensing the particles continuously. Gas and/or particles as a detection target substance that are attached to an authentication targetare removed by air flow from a blowing region. The removed sample is sucked and is condensed and sampled at a sampling region, and ions of the sample are generated at an ion sourceand are then subjected to mass analysis at a mass analysis region. Determination of the obtained mass spectrum is made as to the presence or not of a mass spectrum derived from the detection target substance, and a monitordisplays a result thereof. Thereby, the detection target substance attached to the authentication targetcan be detected continuously in real time, promptly and with a less error rate.

In the manufacture of a gas discharge type display panel, by applying a sealing operation along with an exhausting operation, the sealing glassis broken down by a pressure difference between the inside and outside of the panel, and thus, the clearance gap between the substrates can be controlled as desired. In addition, the gaseous component that is unnecessary for the discharge operation is exhausted by setting the temperature of the amorphous sealing glass to exceed its softening-point and be no more than its working point. In the structure of the gas discharge type display panel, a protruding portion having a radius of curvature between 0.1 mm and 1 mm is formed on the sealing glass to reduce the dispersion in the thickness direction of the sealing glass, or the cross-sectional shape of the sealing glass is made convex both at its inside end part and its outside end part.
