Title: Farm wheel
Inventor: ARIMURA KAGEYUKI
IPC: A01C11/02
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To moderate vibration and impact and improve a tractive force by setting the ratio of the sectional height of an elastic body to the depth of a rib within a specified range. SOLUTION: In a wheel 3, the outer diameter is 650 mm, the tire width is 80 mm, the ring sectional height A is 111 mm, the rib depth (the height of a cutout part 10a) B is 22 mm, and the circumferential length C of the rib 10 is 29 mm. Further, in a rim 8 shown by a round pipe, the coating thickness of the rim 8 is increased by reducing the outer diameter thereof. Namely, B/A×100 is 19.8%, and B/C×100 is 75.9%. Accordingly, the rigidity of the rib 10 is suppressed by setting the depth B of the rib 10 large to the sectional height of an elastic ring body 9 (B/A×100 is 15-30%), and the traction force is improved by increasing the raised surface 10b in the cutout part 10a.

Abstract: PURPOSE: To improve the surface hardness and the gas barrier properties of a bottle made of a saturated polyester, by applying a thermosetting resin primer layer and a coating layer to the outer surface of the body of the bottle, and irradiating the layers with ultraviolet rays thereby forming a hard resin coating layer.  
     CONSTITUTION: A bottle 2 made of a saturated polyester and having biaxially oriented body 1 is washed with water. A primer layers 6 or 9 of about 1W10μ in thickness is applied to the outer surface of the wall 5, 8 of the body by coating the surface with a coating agent composed of a thermosetting resin such as urea resin, etc., followed by heating. The primer layer is coated with a coating agent composed of a synthetic resin capable of forming a hard surface and a clear coating film, e.g. epoxy resin, etc. containing a photo-sensitizer such as benzoin, etc., to obtain a coating resin layer 7, 10 of about 5W45μ in thickness. The resin layer 10 is, if necessary, coated with another coating resin layer 11, and the whole layers are irradiated with ultraviolet rays.

Title: Light emitting device
Inventor: NAKAGAWA KIYOKAZU
IPC: H01L31/10
Filed: 1994-06-07
Abstract: PURPOSE:To enlarge the confinement of carriers and a light simultaneously by a method wherein a distortion-type structure in which the lattice constant difference between a buffer layer and a light emitting layer is not less than a specific value is employed. CONSTITUTION:A p<+>-type Si layer 112 is built up on a p<+>-type Si (100) substrate 111. Further, a p-type Si layer 113 is built up and an i-type Si layer 114 which is not doped with impurities is built up on the layer 113. Then a very thin film of an i-type Si0.7Ge0.3 layer 115 which is a light emitting layer and is not doped with impurities is built up. Further, an i-type Si layer 116 and an i-type Si0.7Ge0.3 layer 117 are built up under the same substrate temperature and this process is repeated. Finally, an i-type Si layer 118, an n-type Si layer 119 and an n<+>-type Si electrode layer 120 are built up. The total thickness of the layer 116 and the layer 117, i.e., the pitch of a multilayer film is so selected as to be a half of the wavelength. At that time, a distortion-type structure in which the lattice constant difference between the buffer layer and the light emitting layer is not less than 0.4 is employed. With this constitution, the multilayer film functions as an interference device of a light and only a light having a wavelength twice the pitch exists.

Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To obtain a signal having the sufficient level needed for a tracking control even when a groove is extinguished from an optical recording medium on which pits indicating an information signal are formed at least in one part of a recording track in order to enhance productivity. SOLUTION: On a recording track on which pits are formed, areas where pits are formed are made more numerous than areas where pits are not formed. Specifically, in an information signal which is binarized into '0's and '1's, since the occurrence probability of '0's is higher than that of '1's in normal times, pits are formed in places corresponding to the '0's of the information signal.

Title: Reproducer of color video signal
Inventor: SHIYUWARUTSU MANFURETSUDO
IPC: H04N9/87
Filed: 1983-07-09
Abstract: PURPOSE:To reproduce color video signals of high quality by using the correction to elsignal iminate the carrier wave component or higher harmonic component of a low band color signal which is mixed into a reproduced luminance signal as an undesired luminance signal component. CONSTITUTION:Luminance signal reproducing circuit parts 6-9 demodulate the frequency modulated luminance signal obtained from a magnetic recording medium to obtain a reproduced luminance signal Y. This demodulated signal contains undesired signals Cxa and Cxb consisting of the carrier wave component or higher harmonic component of a low band color signal. A color signal reproducing circuit part 100 converts the frequencies of low band carrier color signals Ca and Cb and deletes the crosstalk component of the adjacent track to obtain a reproduced carrier color signal C. A correcting circuit part 27 converts the frequency of said signal C and produces a correction signal corresponding to the frequency of said undesired signal. Then the part 27 gives the phase control to the correction signal so as to obtain the opposite phase to the undesired signal and applies it to an adder 10. The adder 10 adds the correction signal to the demodulation outputs of the parts 6-9 and deletes the undesired signals mixed into those demodulation outputs.
