Title: Cooling device for lubrication oil
Inventor: FUJII SATOSHI
IPC: F01P1/06
Filed: 2001-06-22
Abstract: PROBLEM TO BE SOLVED: To avoid an oil filter from protruding much from an engine main body, even in the case in which a pressure oil path which provides a function similar to an oil cooler is provided with the oil filter by dispensing with the oil cooler as a separate part, which results in no requirement for the lead-out oil path for the oil cooler, resulting in the reduced cost of a oil cooling device.

Title: Optical disk device
Inventor: FUKUMOTO MAKOTO
IPC: G11B7/1267
Filed: 2001-06-25
Abstract: PROBLEM TO BE SOLVED: To set a reference value β when executing optimization for record power(OPC) in an optical disk device. SOLUTION: Test data is recorded on the test area (PCA) of the optical disk 100 by variously varying the record power and then reproduced by a signal processing part 16. The value β of a reproducing RF signal in each record power from a reproducing signal is calculated and then the inclination of the value β to the record power and the change rate of the inclination are calculated in a control part 14. A range that the change rate of the inclination is lower than a predetermined value is judged as a range that heat waveform distortion is generated, and the reference value β is selected from a range that the heat waveform distortion is not generated and then the data of the record power that can obtain this reference value β is recorded as optimum record power.

Title: Far infrared magnetic radiator
Inventor: KOMATSUZAKI YASUO
IPC: A61N5/06
Filed: 2001-07-13
Abstract: PROBLEM TO BE SOLVED: To provide a thin and lightweight far infrared magnetic radiator capable of simultaneously radiating far infrared ray and magnetism to a wide range in a specified region of a human body with a high density. SOLUTION: A ceramic layer 3 for radiating the far infrared ray is formed on one side of a foil-like metal plate 2 by baking or flame coating. A magnet 1 is adhered to the other side of the metal plate 2, and a reinforcing member 4 is also adhered, whereby this far infrared magnetic radiator is obtained. Since the metal plate 2 is separated from the magnet, and the ceramic layer 3 is formed on the metal plate 2 by baking or flame coating, the heat by the baking or flame coating is never applied to the magnet 1, the magnetomotive force is thus never deteriorated.  Since the magnetism and far infrared ray can be simultaneously radiated to the region of the human body to which this far infrared magnetic radiator is attached, a synergistic effect of magnetism and far infrared ray can be obtained, the blood circulation can be enhanced to improve a disease, and a health promoting effect can be produced.
