摘要： PROBLEM TO BE SOLVED: To maintain a photocatalistic function even if a part of a illuminant is failed and improve a reliability by combining plural light-emitting diodes as the illuminant with a photocatalyst carrier and juxtaposing them. SOLUTION: Plural light-emitting diodes 1 is mounted on a substrate 2 by a lead frame so that light illuminates a photocatalyst 4 of a photocatalyst carrier member 3. The light-emitting diodes which are mounted are small size, and a LED grid unit 6 is composed by arranging the small light-emitting diodes 1 like a grid regularly. Both zigzag and irregular arrangements are acceptable. The photocatalyst carrier member 3 is born with the photocatalyst 4 by being glued with an adhesive or a binder and so forth or by being incorporated the adhesive or binder directly. Thereby, the photocatalyst 4 can be irradiated by light of at least two illuminants 1, therefor, if one of the illuminants is failed, the photocatalyst 4 is irradiated continuously and an antibacterial function and a deodorizing function can be maintained.

摘要： PROBLEM TO BE SOLVED: To reduce time for drying and power consumption by passing the circulation of hot air through alternately at least from two directions with respect to clothing by a flowing direction changeover means in a clothing drier drying clothing by passing hot air through gaps within clothing in a drying room and around the clothing. SOLUTION: When the flowing direction of hot air starts from a hot air flowing direction 16 which passes upward from a lower side with respect to the clothing within the drying room 2 to dry the clothing, aperture parts 11b and 11c are closed with covers 12 and 12b by a power motor 9 to open aperture parts 11a and 11d. Hot air of low humidity and high temperature heated by a condenser 6 within a freezing unit 4 at this time returns from the part 11d to flow into the room 2 through a channel 3 to heat and dry the clothing. In addition, the parts 11a and 11d are closed with the covers 12a and 12b by the motor 9 at an appropriate time at this time to switch the parts 11b and 11c into an opened state to switch the blowing direction of hot air from downward to upward to remarkably reduce drying time.

摘要： PROBLEM TO BE SOLVED: To easily hang clothes from a hanger and to easily hang the hanger so as to attain efficient dehydration by constituting the hanger from a rigid body, providing a passage for permitting air to flow inside the hanger and providing air flow-in and flow-out holes linked with the passage. SOLUTION: The flow-in hole 2 for air (hot blow) 6 and a hook 3 for hanging are provided in the upper part of the hanger 1, the plural flow-out holes 4 are provided in the neighborhood of the lower part of the hanger 1 and the flow-in hole 2 and the flow-out holes 4 are linked by the passage 5. Therefore, air 6 is permitted to flow from one flow-in hole 2 with a large diameter into the hanger 1 so as to be blown against the inner surface of the clothes 7 from the respective flow-out holes 4 while passing through the inner passage 5. After that, most of air 6 is made to flow inside the clothes 7 so as to be flown out of them from the lower part while a part of it is leaked to the outside of clothes 7. Then, efficient dehydration is executed by blow from the inside of the clothes 7. Besides, more efficient dehydration is executed when the outer surface of the clothes 7 is dehydrated by blow.

摘要： PURPOSE:To accurately measure the displacement of a mirror part without being affected by temperature variation by adhering the interference optical part of the instrument in one body. CONSTITUTION:The interference optical system 3 is constituted by adhering a polarization beam splitter (PBS) 4 and 1/4-wavelength plates 5 and 7 in one body. Light beams B1 and B2 emitted by a laser 1 reach a beam splitter (BS)2 and are split into B1T and B2T, and reflected light beams B1R and B2R. Further, when components which vibrate at 45 deg. to the paper surface are extracted by a polarizing plate 9 from the reflected light beams B1R and B2R, they interfere with each other to generate beats of the frequency difference between the two light beams. They are converted by a photodetector 11 into an electric signal, whose zero cross points are detected 13 to generate pulses. They are inputted to the down input terminal of an up/down counter 15 and counted. Then, the transmitted light beams B1T and B2T of the BS2 reach the PBS4. The transmitted light B1T is transmitted through the wavelength plate 7, reflected by an object 8 of measurement, and transmitted through the wavelength plate 7 again to reach the PBS4. At this time, the light is shifted in frequency in proportion to the speed of the object 8 of measurement.

摘要： PURPOSE:To reduce the entire temperature rise, to suppress the temperature rise of a magnetic disk itself and to uniformize the temperature distribution by providing a heat pipe in a way that a heat absorbing part between disks and a heat dissipation part is placed at the outside of housing. CONSTITUTION:When the magnetic disk 1 is driven at a high speed, a wind loss is caused by fluid friction with surrounding air, the magnetic disk 1 is heated and the temperature rises. Thus, the heat generated by the magnetic disk 1 is delivered from the heat absorbing part 10 of the heat pipe 9 inserted between disks into the heat pipe 9, led to a heat dissipation part 11 by a medium in the heat pipe 9, dissipated into the external air of the housing 8 via a heat sink fin 12. Since the heat absorbing part 10 of the heat pipe 9 is placed among the disks, the heat transfer rate is large by air flow due to the revolution of the magnetic disk 1, the heat of the disk 1 id delivered excellently to the heat pipe 9 and cooled forcibly by a blower 13, then the heat is dissipated efficiently.

摘要： PURPOSE:To remarkably improve the overall heat radiating performance by forcively sending the air flow generated by the rotation of the disc to the gap part of a voice coil motor, and providing an air guide to the yoke at the air- flow inlet of the gap part. CONSTITUTION:The air flow generated by the rotation of the magnetic disc 1 is exhausted from an air exhaust 4 provided in the reference surface of a housing 2. After passing through an actuator part, the air flow is sent to the gap part 16 of the voice coil motor. It further goes through a passage 17 provided in a magnet 14 which is a magnetic circuit part, and through a filter 21 in a passage 20 provided to a cover 12, and is returned to the inside of the housing 2 from an air flow entrance 6 provided in the reference surface of the housing 2 aforementioned. In the air circulation system that includes an air guide 25, the air exhausted form the air exhaust 4 is forcively sent into the air guide gap 26 which is a narrow clearance and into the voice coil motor gap 16, therefore, a high-speed air flow is generated at respective gap parts 26 and 16. As a result, the heat radiation performance of the coil 9 is markedly improved.
