Title: Check system for wavelength channel signal
Inventor: TOOMASU ROOSON KOTSUSHIYU
IPC: H04B10/572
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To provide a system and method to decide whether or not a channel signal carried by each wavelength channel is located in the center of a substantial wavelength channel. SOLUTION: This wavelength division multiplex system is provided with a multiplexer configuration which is adopted to detect a proper signal is properly corrected and an improper signal is corrected into a proper signal. This system is provided with a signal generator overlapping a secondary signal onto an original signal in a signal channel. The secondary signal is a tone signal subjected to intensity modulation and has a shallow modulation depth and adjacent frequency and amplitude. Thus, the cross reference with an intended optical signal to occupy a wavelength channel to be assigned to a specific tone (that is, secondary signal) is established.

Title: Focusing error detector for optical pickup
Inventor: HAYASHI HIDEAKI
IPC: G11B7/13
Filed: 1989-02-15
Abstract: PURPOSE:To always perform focusing error detection with a few error by providing first and second bi-sected light receivers arranged at the front of a first convergence point and the rear of a second convergence point and divided into two, respectively at a detector. CONSTITUTION:The detector 6 is provided with light receiving planes 15-17, and the light receiving planes 15 and 17 are divided into planes 15A, 15B and 17C, 17D by parting lines 15L and 17L. Since the light receiving plane of the detector is arranged obliquely against an optical beam 11, it follows that the light receiving planes 15 and 17 are arranged at the rear and the front of the light receiving plane 16 (focal point position F). Here, the beam spots 9U and 9D of the reflected light 11 reflected on the planes 15 and 17 at the time of focusing are provided with almost equal diameters. Next, when a distance between an optical disk 5 and an objective lens 4 is reduced, a beam spot C is focused behind the position F, therefore, the spot 9U goes to the spot small in diameter, and the spots 9D and also 9C go to the ones large in diameter, and adversely, when the distance is increased, the spot 9U goes to the one large in diameter, and the spot 9D small in diameter, and the spot 9C large in diameter. The focal point position can be detected by the difference in the diameter of the spot, and the error can remarkably be reduced by an arithmetic operation.

Title: Production of catalyst for purification of exhaust gas from internal combustion engine or the like
Inventor: TAKANASHI MASAKAZU
IPC: B01D53/56
Filed: 1999-01-04
Abstract: PROBLEM TO BE SOLVED: To purify a harmful component exhausted from an internal combustion engine or the like to convert into a harmless component by introducing the harmful component into an aq. soln. containing calcium. SOLUTION: The harmful component discharged from an exhaust gas of an automobile includes carbon monoxide, nitrogen monoxide and nitrogen dioxide. In order to purify the harmful component, the exit of the exhaust gas is provided with a tank containing water and calcium carbonate to purify the harmful component by the chemical reaction. Namely, when the exhaust gas or carbon monoxide is introduced into water, water is first coupled with carbon monoxide to change into carbon dioxide and hydrogen. Then nitrogen monoxide is coupled with hydrogen to change into nitrogen and water. Then 2N2O is converted into 2N2 and oxygen, or water is coupled with nitrogen dioxide to change into nitric acid and nitrous acid.  Thereby, nitric acid and calcium carbonate are converted into water, carbon dioxide and calcium nitrate, which means the harmful component is converted into a harmless component of the combination of water, carbon dioxide, nitrogen and oxygen or the like.

Title: Gear shift device of multi-step gearing transmission
Inventor: YAMAUCHI KOSAKU
IPC: F16H61/30
Filed: 1989-02-16
Abstract: PURPOSE:To lessen the restriction in designing installation of a change cam cylinder by coupling pressurizing chambers in front of and behind a pressurizing cylinder with pressure receiving chambers in front of and behind a pressure receiving cylinder through hoses, and turning the change cam cylinder for a certain angle one by one through the swinging action of a swing pinion. CONSTITUTION:Pressurizing chambers 3 are formed on both sides of a plunger 2 of a pressurizing cylinder 1, while pressure receiving chambers 13 are formed on both sides of a pressure receiving plunger 11 of a pressure receiving cylinder 10. The pressurizing chambers 3 are coupled with the pressure receiving chambers 13 through hoses 14. When a change lever 6 is stamped down, the plunger 2 is pulled to cause the oil in the pressurizing chambers 3 to give an oil pressure to the pressure receiving chambers 13 through the hoses 14, which pushes out the pressure receiving plunger 11 to cause a rack 15 to swing a swing pinion 18, and thereby a change cam cylinder 16 is rotated for a certain angle. If this stamping motion of the change lever 6 is repeated, rotation of the change cam cylinder 16 proceeds one by one, and transmission gears are shifted to higher side one by one. Operation of the change lever 6 in the direction of off-stamping, on the contrary, will shift in the direction to lower side.
