摘要:
Disclosed is an organic electroluminescent device (organic EL device) which is improved in luminous efficiency, fully secured of high driving stability, and of a simple structure. The organic EL device is constituted of an anode, organic layers containing a phosphorescent light-emitting layer, and a cathode piled one upon another on a substrate and a phosphine oxide derivative represented by general formula (1) is contained in a phosphorescent light-emitting layer, an electron-transporting layer, a hole-blocking layer, or an exciton-blocking layer. In general formula (1), L1 is a direct bond or an aromatic group with a valence of 1-3 and Ar1 is an aromatic group. The two Ar1 groups linked to the same nitrogen atom may form a nitrogen heterocycle and may further form a fused ring together with the said nitrogen heterocycle.

The present invention provides an ear thermometer that irradiates liquid crystal with backlight without increasing a battery capacity, to make a body temperature displayed with the liquid crystal easily visible even in a dark place. An MCU 1 displays a body temperature measured by a body temperature measuring part (3) on a liquid crystal display part (5), controls, through input/output ports (P1, P2), a backlight emitting part (7) in such a way that the light quantity of the backlight irradiating the liquid crystal display part (5) from the backlight emitting part (7) is maximized for a first predetermined time, controls the backlight emitting part (7) in such a way that the quantity of the backlight keeps, for a second predetermined time that follows the first predetermined time, a predetermined level that is lower than the maximum, and controls the backlight emitting part (7) in such a way that the quantity of the backlight is zeroed after the second predetermined time elapses.

An information access system includes a reader/writer device and an information storage device. In the information storage device, a receiver unit senses a carrier of an RF signal at a first frequency for detection, in a first time period occurring at time intervals, and receives an information request signal in response to detection of a carrier of an RF signal at the first frequency, and senses a carrier of an RF signal at a second frequency in response to reception of the information request signal. In the storage device, a control causes the receiver unit to sense a carrier of an RF signal at the first frequency for detection, in a second time period after a sleep time period which is shorter than the time interval, in response to non-detection by the receiver unit of a carrier of an RF signal at the first frequency in the first time period.

An object of the present invention is to solve the bending of an NMR probe and a room temperature shim coil so that they can be positioned easily. In the NMR spectrometer including split-pair magnets and a cross bore, a high rigidity straight pipe to which an NMR probe and a room temperature shim coil are attached so as to make an integral object, is provided. The outer diameter of the straight pipe is smaller than the inner diameter of a horizontal bore into which the room temperature shim coil and the probe are inserted. After the room temperature shim coil and the NMR probe are attached to the straight pipe by bolts, respectively, the integral object is inserted into the horizontal bore (a room temperature space) of the NMR spectrometer. The room temperature shim coil and the probe may be attached to different straight pipes.

A probe of an ear-type clinical thermometer 20 comprises a first heat insulation member 210 made of a resin material and a second high heat insulation member 220 made of a resin material that is connected to a distal end of the first heat insulation member 210 by conventional coupling means. The second high heat insulation member 220 is tapered forwardly and is provided on the distal end with a concave surface 221. A protection cover 230 sheathes the first heat insulation member 210 and second high heat insulation member 220. A thermistor fine lead wire 240 is embedded in the first heat insulation member 210 and second high heat insulation member 220 so that a turning end portion 241 of the wire 240 is bridged over the concave surface 221 of the second high heat insulation member 220 to be exposed above the concave surface 221. An ultrafast responsivity thermistor 250 is mounted substantially on a center of the turning end portion 241 of the thermistor fine lead wire 240.
