A damper is provided to suppress the abnormal noise or air noise at the small opening of the damper. The damper includes a wall surface which forms an air flow passage, a stationary portion which extends from the wall surface to the center of a flow passage, and a rotating portion rotatably disposed in the flow passage, having one end in contact with a portion of the stationary portion at a downstream side of an air flow through the flow passage. A curved wall portion as a convex curved surface protruding to the center of the flow passage is formed on a position of the wall surface on which the air flow passing between the one end and the stationary portion impinges.

A printing apparatus with a plug-and-play execution unit includes a plug-and-play control unit and a permission receiving unit. The plug-and-play execution unit can perform predetermined communication processing with an external control apparatus, and the predetermined communication processing is triggered by a connection with the control apparatus when the connection is established via a predetermined communication path. The plug-and-play control unit is configured to prohibit the plug-and-play execution unit from operating in a case where an instruction for activating the printing apparatus according to a specific operation mode is received from an outside source, so that the plug-and-play execution unit is prevented from performing the communication processing. The permission receiving unit is configured to receive permission for execution of plug and play. In a case where the permission for execution is received, the plug-and-play control unit cancels the prohibition of operation of the plug-and-play execution unit.

To provide a seat having a three-dimensional complex undulated cushion body securing hardness in a stress direction and excelling in dispersibility of the stress and durability, and a method of manufacturing the same.A seat 1 includes frames (15, 25), cushion bodies (11, 21) obtained by forming a plurality of sheet-like fibrous structures 4a to 4d integrally, and covers (13, 23), wherein a sheet-like fibrous structure 4 is formed by performing cotton blending of thermally adhesive composite short fibers to inelastic crimped short fibers and thermally adhering crossing points, and the sheet-like fibrous structure 4 satisfies a relationship of A≧3B/2 when the number of short fibers arranged along a thickness direction is represented as A and the number of short fibers arranged along a direction perpendicular to the thickness direction is represented as B, and the cushion bodies 11, 21 are obtained by disposing in a state in which the sheet-like fibrous structures 4a to 4d are stacked and compressed in a mold 40, and forming the sheet-like fibrous structures 4a to 4d integrally by performing high pressure steam molding, and provided on the frames 15, 25 such that a thickness direction extends along a direction in which a load is applied.
摘要:
A function for checking whether components of an automatic analyzer properly operate is made available. A pressure sensor is installed in a sample path. A pressure waveform obtained during a washing water discharge operation 10 is used to check the opening/closing of a solenoid valve and the other operations of a dispensing mechanism. This function can also be exercised when a pressure sensor for a conventional sample suction check process is used. Even when the solenoid valve fails to open or close, an alarm is issued to indicate such a failure. This makes it possible to prevent a sample from thinning, thereby providing enhanced data reliability.

A booster circuit includes a first booster unit configured to boost a power supply voltage to a predetermined voltage value, a transfer gate transistor transferring the voltage received from the first booster unit to an output terminal, a switching transistor connected between an input terminal receiving the voltage from the first booster unit and a gate electrode of the transfer gate transistor, and a second booster unit configured to boost a voltage applied to a gate electrode of the switching transistor. The second booster unit includes an NMOS booster transistor. A drain electrode of the booster transistor is connected to the output terminal, a source terminal of the booster transistor is connected to a terminal to which a boosted voltage is to be applied, and a gate electrode of the booster transistor is connected to a booster capacitor.
