A bodily state detection apparatus comprising a CCD camera, an infrared LED device, a pickup image memory, a pupil extraction circuit and a bodily state judgment circuit. The CCD camera inputs images of a predetermined area including the subject person's face. The infrared LED device illuminates the subject person in such a way that the optical axis of the camera and the direction of the illumination coincide with each other. The pickup image memory stores temporarily the output data of the CCD camera. The pupil extraction circuit extracts the subject person's pupil position from the pickup images. The bodily state judgment circuit judges the subject person's bodily state by use of the result of pupil extraction performed by the pupil extraction circuit.

A compact and effective ventilator/drier assembly for heating the room to which it is installed has a case main body 1 divided into a primary zone 3A communicating with an air inlet port 2A, a tertiary zone 3C communicating with an air outlet port 2B and a secondary zone 3B disposed adjacent to the tertiary zone and the primary zone. Moist air A in a room 100 is forced to flow through the air inlet port, the primary zone, the secondary zone, the tertiary zone and the air outlet port and back into the room by a centrifugal type air blower 21 and moisture contained in the room air is adsorbed by a cylindrical rotary type moisture adsorbing device 31 arranged between the secondary zone and the tertiary zone as the air is made to come into contact with a moisture-removing portion 31A of the adsorbing device 31. Dried air B is moved to into the tertiary zone, where it is heated to produce heating air E, which is discharged from the air outlet port into the room. At the same time, the heat recovered by the heat recovering portion 31C of the rotary type moisture adsorbing device is utilized to heat regenerating air C, which is led to the tertiary zone by a drying/heating changeover damper 48 and then discharged from the air outlet port.

A tubular single-layer winding coil is installed on the outer periphery of a thin wall portion of a cylindrical container case and a columnar electrode is provided at the center of the inside of the cylindrical container case. A fuel channel is formed between the coil and the electrode so that the permittivity of fuel flowing through the fuel channel is detected from the electrostatic capacity therebetween. Further, variation of the electrostatic capacity due to the temperature characteristics of the fuel is compensated by the temperature characteristics of the permittivity of the thin wall portion of the sensor unit. Furthermore, variation of the electrostatic capacity due to the temperature characteristics of the fuel is compensated by the temperature compensation capacitor which is connected with the single layer winding coil in parallel.

A sintered silicon nitride excellent in high temperature performance is produced by the following method: First, silicon nitride powder and oxide of at least one element selected from elements in the group IIIb of a periodic table are mixed with each other to obtain a mixture. The silicon nitride powder contains silicon oxide in an amount ranging from 0.1% by weight of the silicon nitride powder to a value not more than a content of the silicon oxide. Second, the mixture is compacted to form a compact. Finally, the compact is fired in atmosphere of nitrogen at a pressure ranging from 5 to 200 atmosphere (atm) and a temperature ranging from 1800.degree. to 2000.degree. C. to obtain a sintered silicon nitrite having a bulk density not less than 95% of a theoretical density of the sintered silicon nitride.
摘要:
A space frame comprises an upper frame body and a lower frame body both constructed with square steel tubular members; and diagonal members joining the upper frame body to the lower frame body. Each pair of two perpendicular sides of each of the square steel tubular members forming the lower frame body are arranged to make an angle of about 45 degrees to the plane of the lower frame body. The diagonal members are arranged to cross at an angle of about 45 degrees to bar members both of the upper and lower frame bodies. The space frame provides increased buckling strength because the bar members and the diagonal members may be entirely joined by welding.
