Title: Dust collector
Inventor: YASHIRO KAZUHIKO
IPC: B01D46/02
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To detect leakage of dust collection from a filter by a simple method by providing a window part on the side of an intermediate room provided between a fan and the filter and providing a transparent cover made of a transparent substance on the window part. SOLUTION: An intermediate room 18 exists between a fan 3 and a filter 5 and a window part 19 is provided on the side face of the intermediate room 18 and a transparent cover is fixed on the window part 19 under a removable condition through a packing, a screw, etc. The transparent cover consists of a transparent substance, e.g. an acrylic sheet, a glass sheet, etc. Then, if dust leaks from the filter, it is contaminated by sticking of the dust and the transparency disappears and the inside of a machine body becomes invisible from the outside of the machine body. Therefore, it is possible to easily detect leakage of dust from the outside of the machine body caused by contamination of the transparent cover.

Title: Optical device
Inventor: AOYAMA TSUTOMU
IPC: G02B7/00
Filed: 1979-04-26
Abstract: PURPOSE: To reduce the insertion loss of the optical device and increase the efficiency of assembling work by bonding optical parts such as optcial fibers or lenses into the body of the blocks or optical device opened with the holes of an inside diameter slightly larger than the outside diameter of the parts, by means of adhesive agents.  
     CONSTITUTION: For example, in the optical device which consists of optical fibers 1, 2, lenses 3, 4 and a means 6 of attenuating light, the lenses 3 and 4 are so position-adjusted that the insertion loss of the optical device becomes minimum, after which they are fixed into the blocks 5 being provided with the through-holes slightly larger than the outside diameters of these lenses by flowing adhesive agents 8 into the clearance between the lenses and blocks. Even if the adhesive agents cause a large volume change when set, there is no problem and the adhesive agents of a short set time are usable as well. Since the position deviations at the lens fixing are less, the increase in the insertion loss of the optical device is less. This fixing method is particularly highly effectual for the optical device for single-mode fibers.

IPC: G02F1/035
Filed: 1990-03-02
Abstract: PURPOSE:To manufacture a wide-band optical waveguide type modulator and an optical switch by making a chip sufficiently small in thickness and width and shifting the resonance frequency of a microwave to a high frequency outside an in-use band. CONSTITUTION:The chip is so formed that a beltlike waveguide 2 formed by diffusing titanium thermally in a waveguide substrate 1 has a branch part and a coupling part at both ends and also has mutually parallel parts in the center. Then the chip width and thickness are so determined that the product of the largest length (d) in chip section perpendicular to the waveguide 2 and the effective refractive index nm of a microwave in this direction is 0.8-11mm. Namely, the product nm of the diagonal length of the chip section and the effective refractive index nm of the microwave in the direction (d) is set so that 0.8<nmd<11(mm). Therefore, the resonance frequency can be shifted to a high frequency side. Consequently, excellent frequency characteristics are obtained.

Filed: 1991-03-18
Abstract: PURPOSE:To enhance recording density without lowering the positioning precision of a magnetic head by orienting the axis of the easy magnetization of the magnetic film of a magnetic disc to a circumferential direction and obtaining magnetic anisotropy. CONSTITUTION:Plural magnetic disks 13 are attached to a spindle 12, the spindle 12 is driven by a motor 14, the magnetic head 15 is positioned by a carriage 16 and a voice coil motor 17. The magnetic disk 13 is obtained by forming a substrate film 2 on the surface of the disk 1, processing with rubbing while rotating an obtained base board, forming an intermediate layer 3, the magnetic film 4 and a protective film 5 on the processed base board and forming numbers of projecting parts on the surface of the film 5. In this case, the magnetic anisotropy in the circumferential direction where coercive force to the circumferential direction is more increased than the coercive force in the radial direction participating with no recording is imparted by orienting the axis of the easy magnetization of the film 4 to the circumferential direction. The value of the coercive force in the circumferential direction of the film 4 is defined as 1.2 times the coercive force in the radial direction. Thus, the facial recording density is enhanced to, e.g. >=100Mb/in<2>.

Title: Device for evaluating and testing durability of painted film metallic product
Inventor: OKADA TATSUHIRO
IPC: G01N17/00
Filed: 1985-03-15
Abstract: PURPOSE:To evaluate continuously and quantatively the deteriorating behavior of a test piece and the degree of corrosion by immersing the half of the coated metallic test piece in a corrosive solution, bringing its upper part into contact with a corrosive gas, etc., so as to prompt its deterioration and measuring an electro-chemical characteristic value. CONSTITUTION:The container of a testing device is segmented by a partition 4 to divide a solution into gaseous and liquid phases. A coated metallic test piece holder 3 is semi- immersed in the liquid phase, and its upper part is brought into contact with the gaseous phase to rotate the holder 3. A reference electrode 8, a counter electrode 9, a heater 11, a heater sensor 10, etc., are installed in the liquid phase. In the gaseous phase, a ultraviolet ray lamp 5, corrosive gas introducing tubes, etc., are installed. The test piece is fitted on the holder 3 and rotated. Then its deterioration is accelerated by giving a wetting and drying cycle and corrosion and light irradiation cycles. At this time a potential between the reference electrode made of silver chloride, etc., and the counter electrode of a gold wire is measured. Here, the polarized resistance at the early stage is about 10<9>OMEGAcm<2>, which means a large resistance, however, it decreases to about 10<5>-10<6>OMEGAcm<2> as the coated film deteriorates. Thus the corrosive behaviors of the coated film and a base metal can be known electro-chemically, whereby durability can be judged.
