Title: Spherically pointed fibre lens and its formation
Inventor: KIMURA MITSUTERU
IPC: G02B6/10
Filed: 1994-06-03
Abstract: PURPOSE:To collimate the light emitted from an optical fiber to nearly parallel rays and to efficiently couple the parallel rays reverse therefrom to this optical fiber by specifying the distance between the terminal of a core and the central part of the optical axis of a spherical front end from which the light is emitted. CONSTITUTION:A method for determining the position of the terminal part A of the core from the beginning by cutting the optical fiber is adopted. The average radius R of curvature is so adjusted by melting conditions that the distance L between the terminal part A of the core and the central part C at the optical axis of the spherical front end is made nearly three-fold the average radius R of curvature at the time of forming the spherical end. The terminal part A of the core is formed by cutting the optical fiber in such a case. An equally possible alternative is to form the terminal part A of the core by melting the middle part of the optical fiber, then to form the spherical front at the optical fiber at its front. At this time, the average radius R of curvature of the spherical end is so adjusted by the melting conditions that the distance between the terminal part A of the core and the central part C at the optical axis of the spherical front end is made nearly three-fold the average radius R of curvature.

Abstract: PURPOSE:To maintain the stable operation of the title unit by providing a chamber box having a nozzle-shaped air outlet port opened in the same direction as the opening direction of an air intake port over a sirocco fan that is rotated by a motor disposed in the interior of a casing. CONSTITUTION:A static pressure necessary for blowing air and an outlet air speed can be sufficiently secured by means of a sirocco fan 26 and a nozzle- shaped air outlet port 23, whereby the lack of the air quantity of an outlet air current and blowing inability can be obviated. Since the air outlet port 23 is formed so as to open at the front part of a casing 1, the impingement of the outlet air current against the veranda of an upper floor may be avoided during the operation of the unit, even if the casing 1 is installed on a veranda and the like on each of floors in a multifloor building. During a cooling operation, an outdoor side heat exchanger 7 acts as a condenser, and the temperature thereof rises. In this instance, the sirocco fan 26 is rotated by the drive of a motor 25, whereby outdoor air sucked in the unit through an air intake port 5 passes through the outdoor side heat exchanger 7 and then through a space 22 as warm air to be discharged in the forward direction of the casing through the air outlet port 23.

Title: Production of die for precision casting
Inventor: MORITA TOSHIJI
IPC: B22C9/06
Filed: 1984-06-14
Abstract: PURPOSE:To reduce the time and man-hour from the preparation of a casting mold to the end of casting and to obtain precision casting dies for multiple kinds and small-quantity production by working directly a boron nitride ingot to form the casting mold and casting the dies under specific conditions. CONSTITUTION:The boron niride ingot is machined by allowing for the shrinkage of the cast steel which is a die material to form a drag. The drag is installed in a calcination furnace where the drag is gradually heated and the moisture is gradually evaporated away therefrom. The drag is taken out of the calcination furnace while the drag temp. is 500-900 deg.C and a carbon dioxide cope provided with an exothermic sleeve is installed thereto and is clamped. A molten steel having cast steel components is poured into the mold to cast the die. The temp. in the casting stage of the casting mold varies with the shape of the die. The molten steel is liable to solidify and a mis-run arises when the temp. is below 500 deg.C. The molten steel solidifies at a low rate and an increase in the amt. of a riser is necessitated, thus the yield is decreased if the temp. exceeds 900 deg.C.
