Title: Optical disk substrate and its manufacture
Inventor: NAKAGAWA KATSUJI
IPC: G11B7/24085
Filed: 1990-02-26
Abstract: PURPOSE:To prevent recording film or protective film on an optical disk substrate peeling or corroding by forming the bottom of a pit with a curved surface not making at an acute angle. CONSTITUTION:A first photoresist layer 2 and a second photoresist layer 3 are laminated on a glass master disk G. Exposure is performed by irradiating the layers with a laser beam 4, however, at this time, exposure power by which no exposure of a glass substrate 1 is performed on the pit 5 after performing developing treatment is employed as the exposure power of the laser beam 4. Thereby, the bottom of the pit can be comprised of a moderate cured surface without generating the acute angle. In such a way, it is possible to prevent the recording film and the protective film on the optical disk substrate peeling or corroding.

Abstract: PURPOSE:To improve the ultrasonic flaw detectability of a cast steel product of an austenitic stainless steel having 2-phase structure contg. a ferrite phase by deforming plastically said product by refrigerant then subjecting the product to a heat treatment under specific conditions. CONSTITUTION:The cast steel product of the austenitic stainless steel having the 2-phase structure contg. >=5% ferrite is plastically deformed by using a press.

Title: Sealing device
Inventor: UENO HIROSHI
IPC: F16J15/43
Filed: 1987-02-27
Abstract: PURPOSE:To improve the pressure resistance of a sealed portion by providing a cylindrical magnet, two outside shielding plates provided at both ends in the axial direction and each constituted of a circular plate made of a nonmagnetic material, a magnetic fluid, and an inside shielding plate constituted of a circular plate made of a nonmagnetic material. CONSTITUTION:When a pressure difference is generated between the right and left of a sealing device 40 and the pressure at the left side is made larger than that at the right side, for example, a magnetic fluid 44 existing in the circular space at the left tends to be moved to the right side. However, a mass difference is generated between the magnetic fluid 44 in the left side space and the magnetic fluid 44 in the right side space, thus the centrifugal force has a force moving the magnetic fluid 44 from the right side to the left side. In addition, the magnetic force serves as a holding force, and the movement of the magnetic fluid 44 is negated. That is, the magnetic fluid 44 is not moved practically between the right and left circular spaces and firmly held at the holding portion.

Title: Integrated type air conditioner
Inventor: NAGASHIMA HIROYUKI
IPC: F24F1/02
Filed: 1991-03-12
Abstract: PURPOSE:To make the flow speed distribution uniform, and improve the heat exchange efficiency by providing a cushioning filter, for which fine slits or mesh are formed into a conical shape, between a heat exchanger on the indoor side and a sirocco fan on the indoor side. CONSTITUTION:By a negative pressure generated by a sirocco fan 4 on the indoor side, air passes through in the order of a suction grille 13, a cushioning filter 14 and a heat exchanger 3 on the indoor side, and flows into a suction port 5. Since the flow speed of air which passes through the heat exchanger 3 on the indoor side becomes larger as the location becomes close to the suction port 5, the excessive flow speed is reduced by pressure loss when the air passes through fine slits 16a of a cushioning filter 16. Also, by the conical shape of the cushioning filter 16, an auxiliary help to form an air passage from the vicinity of the heat exchanger 3 on the indoor side to the suction port 5 is done, and the flow speed around the heat exchanger 3 on the indoor side is improved, and the air speed distribution for the whole heat exchanger 3 on the indoor side can be unified.

Filed: 1978-04-19
Abstract: PURPOSE:To obtain maximum output in a small size and propagate light to optional optical fiber, by disposing optical fibers on one end side of a self-converging lens which rotates about the central axis and on the end side to which light is converged as being reflected by the plane of reflection of the lens. CONSTITUTION:A reflecting mirror is formed on a self-converging lens on a flat plane including the axis, at positions shown by faces 13' to 18', and when the lens is rotated about the axis until the reflecting mirror comes to face 13', the light from an entrance fiber 12 is converged in an exit fiber 13. When the reflecting mirror comes to face 14', the light is designed to be converged in an exit fiber 14. Thus, when the lens is rotated at an angle of theta around the axis of the lens, the converging position rotates 2theta around the aixs, so that the maximum output may be obtained in a small size. Besides, light may be propagated to an optional optical fiber. It is also possible to pluralize both the entrance fiber and exit fiber.
