Title: Diagnostic device for tissue of living body
Inventor: OTOMO NAOKI
IPC: A61B6/00
Filed: 1993-06-30
Abstract: PURPOSE:To eliminate a need for changing material for new one by preventing matching material or tissue equivalent material from being stained when screening is performed for many testees in a measurement tank. CONSTITUTION:A second measurement tank 34 which admits testees, is detachably formed in a first measurement tank 22 in which at least either one of matching agent and tissue equivalent material is put. Since the testees are not in contact with the matching agent and the tissue equivalent material by means of the second measurement tank 34, the matching agent and the tissue equivalent material will never be stained. Besides, the mounting means of the second measurement tank 34 is detected, and the measured physical quantities of the tissues of each testee are corrected based on correction values inherent to the second measurement tank 34, so that a practical value can thereby be obtained.

Title: Semiconductor laser light source
Inventor: NISHINO SEIJI
IPC: H01S5/00
Filed: 1979-12-14
Abstract: PURPOSE:To eliminate the production of water droplet on a window glass of a semiconductor laser light source by introducing heat generated at a semiconductor laser element through a holder formed of thermal conductor into a semiconductor cooling element and dissipating it externally by a heat dissipating fin making contact with the cooling element, thereby sufficiently cooling the laser element. CONSTITUTION:A semiconductor laser element 11 is contained in a protective container 12 having a window glass 13 for irradiating laser light, and is installed on a holder 14. The holder 14 is formed of thermally conductive material and is formed in trapezoidal shape in cross section to coincide with the heat absorbing surface 26 of a semiconductor cooling element 15 on the bottom surface. The heat dissipating surface of the element 15 is connected to the heat dissipating fin 18 making contact therewith. With this configuration the heat generated at the element 11 is efficiently transmitted through the holder 14 to the element 15. Since the air in the container 12 does not contact with the heat absorbing surface 16, the air in the container 2 is not cooled. Most heat is dissipated from the outer peripheries of the fin 18 and the container 1 into the air, the element 11 is thus sufficiently cooled, and water droplet cannot be put on the window glass 13.

Title: Production of magnetic recording medium
Inventor: CHIBA KAZUNOBU
IPC: G11B5/84
Filed: 1989-06-27
Abstract: PURPOSE:To provide uniform surface treatment on both sides of a medium at one time with relatively simple equipment by running the medium through a mist atmosphere containing a surface treatment agent after forming a ferromagnetic metal thin film on a nonmagnetic substrate. CONSTITUTION:After a ferromagnetic metal thin film and a back coating layer are formed on a nonmagnetic supporting body, the medium is subjected to surface treatment with a lubricant. Surface treatment of the medium is performed by running the medium through a mist atmosphere containing the surface treatment agent to deposite mist particles on the surface of the medium. Since mist particles randomly move in air, the particles contact to both sides of the medium and cover them uniformly. Thereby, surface treatment of the medium can be performed uniformly at one time with using relatively simple equipment.

Abstract: PURPOSE:To exactly read data by deciding the length of an odd-number magnetic domain based on the average value of the odd-number domain and deciding the length of an even-number magnetic domain based on the average value of the even-number domain. CONSTITUTION:When reading magnetic data 1 expressed by the length of the magnetic domain, first of all, an odd-number domain average value calculating means 2 and an even-number domain average value calculating means 3 calculate the average values of the lengths of the odd-number and even-number domains.
