A transport device having a plate; a conveyor to transport articles; a pusher to push and move a row of articles on the conveyor onto the plate; and a stopper to prevent the articles from being moved by the conveyor and to define the start of a row of articles being moved onto the plate by the pusher. The conveyor causes the positions of rows of articles stopped by the stopper to move alternately so that the positions of rows of articles moved onto the plate are shifted alternately.

Transport device and freeze-drying system

A conveyed article sorting device is provided, which has: a conveyor which conveys articles; a track configured such that the articles conveyed by the conveyor can be transferred onto the track from the conveyor; and a rotary gate which can come into contact with the articles on the conveyor; wherein, when an article to be sampled is conveyed by the conveyor, the rotary gate moves the article to be sampled from the conveyor onto the track.

Aiming to more easily perform calibration of a sensor output from a pressure sensor, the calibration being necessitated due to the occurrence of sedimentation, a resonance point measurement unit () measures a resonance point of a diaphragm () on the basis of the result obtained by performing measurement of a constant pressure using the pressure sensor while a power supply frequency is changed, a characteristic calculation unit () calculates, on the basis of the measured resonance point, an elastic modulus of the diaphragm () at the time of the measurement of the resonance point, and a correction unit () calculates a corrected sensor sensitivity resulting from correcting a sensor sensitivity of a sensor chip () on the basis of the elastic modulus calculated by the characteristic calculation unit ().

Pressure sensor

A base plate has pressure introducing holes at positions facing a diaphragm support portion. A thickness portion (thick portion) of the diaphragm support portion and a sensor base joined to the diaphragm support portion thus serves as a heat dissipating or absorbing portion and hinders the transfer of thermal energy of a measured medium to a sensor diaphragm.

Capacitive pressure sensor

A temperature difference calculation unit determines a temperature difference between a temperature measured by a first temperature measurement mechanism and a temperature measured by a second temperature measurement mechanism. The first temperature measurement mechanism is disposed on an outer wall surface of an inner container at a position corresponding to an element-arrangement-side space in the inner container. The second temperature measurement mechanism is disposed on an outer peripheral surface of a heater. The heater is disposed outside an outer container that accommodates the inner container and positioned on a wall surface of the outer container.

A state determination unit compares an output value obtained by a measuring unit with a reference characteristic value that serves as a reference, counts the number of times an excessive pressure application state occurs in which the output value is determined to be equal to or larger than the reference characteristic value, and determines whether the number of times reaches an upper limit that is set. An alarm output unit outputs an alarm when the state determination unit determines that the number of times the output value is equal to or larger than the reference characteristic value reaches the set upper limit.

Vacuum gauge state detection method and system

A pressure change measuring unit causes a temperature control unit to operate and vary the temperature of a sensor chip in a predetermined temperature range, and measures changes in pressure value output from the sensor chip whose temperature is being varied. A temperature characteristic calculating unit calculates a temperature characteristic of the sensor chip from changes in the temperature of the sensor chip caused by the operation of the temperature control unit and changes in pressure value measured by the pressure change measuring unit.

The state of sediment can be estimated based on an initial power supply frequency at which a diaphragm resonates in an initial state in which sediment is not accumulated and a power supply frequency at which the diaphragm resonates after the sediment is accumulated, the state of the sediment can be estimated even in a stage in which the sediment is slightly accumulated on the diaphragm and a zero-point shift does not occur.

Sediment state estimating apparatus, sediment state estimating method, and sediment state estimating system

An electrostatic pressure sensor has a supporting diaphragm bonded to be held between first and second pedestal plates, a sensor chip supported on a top face of a center portion of the second pedestal plate. The supporting diaphragm has in the center portion thereof a large-diameter hole that forms a slit-shaped space between the first and second pedestal plates. The first pedestal plate has at least one inlet hole, for the fluid being measured, connecting to the slit-shaped space. The second pedestal plate has at least an outlet hole, connecting to the slit-shaped space, for directing the fluid being measured to the pressure-sensitive diaphragm of the sensor chip. The pedestal plate has an inlet hole of the first pedestal plate and an outlet hole of the second pedestal plate do not overlap each other in the direction of thickness of the first and second pedestal plates.
