Title: Liquid phase epitaxy apparatus
Inventor: UNNO TSUNEHIRO
IPC: H01L27/15
Filed: 1991-02-05
Abstract: PURPOSE:To stably grow many sheets of layers and to increase a mass- productivity. CONSTITUTION:A raw-material solution holder 8 is installed at the uppermost stage of a growth jig in which many stages of substrate holders 2 and growth- solution holders 5 have been stacked. A solution injection port 9 and a gas/ solution discharge port 10 are formed at each growth-solution holder 5. The solution injection port 9 injects a solution for growth use into a growth-solution reservoir 6 at each growth-solution holder 5. The gas/solution discharge port 10 discharges the following at an injection operation: a gas existing inside the growth-solution holder 5; and the excess portion of the solution for growth use. When the raw-material solution holder 1 is slid, the solution injection port 9 and the gas/solution discharge port 10 are made to communicate with the raw-material solution holder 1 and the growth solution which has been stored in the raw-material solution holder 1 is injected into the growth-solution reservoir 6 at each stage. Since an injection system is adopted, it is not required to make the thickness of the growth-solution reservoir thick, and the solution for growth use which is stored in the growth-solution reservoir can be purified.

Title: Roll heater
Inventor: YAMADA SATOSHI
IPC: H05B6/38
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To change the heat treatment characteristics of a roll without remaking an induction heating coil by arranging a plurality types of members for positioning the coil in such a state that the relative position of the induction heating coil surrounding the roll becomes different in the circumferential direction and by providing a means for rotating the roll for uniformizing the temperature of the roll in the circumferential direction. SOLUTION: Respective positions of an induction heating coil 2 in the circumferential direction which is wound around a roll 1, for example, 4 times are positioned by coil cores 3a, 3b. When the heating treatment characteristics are changed, gaps G1 , G2 formed toward the roll 1 or the heating power are changed according to the coil cores 3a, 3b so that the aimed temperature distribution is obtained. For example, when the gap G1 of the coil core 3a toward the roll 1 is enlarged, an eddy current which is distributed in only the center in the width direction of the roll 1 as shown by a two-dot chain line is changed into such a state as being distributed uniformly across the whole part in the width direction.

Abstract: PURPOSE:To eliminate the need for fine adjustment mechanism for X, Y, Z directions by condensing laser light to the core diameter of an optical fiber or below in a reflection light guide having a light guide formed to a circular conical shape at the time of transmitting the laser light by the optical fiber. CONSTITUTION:The small-diameter part of the reflection light guide 12 is fitted into the aperture of a mouthpiece 11 having a cylindrical shape. The light guide 12 is vapor-deposited or plated with a reflection material on the surface of the light guide 13 in order to enhance the reflection efficiency of the laser light 7 and is formed by using a material having high heat conductivity in order to cool the heat generated by partial absorption of the laser light 7. The optical fiber 4 is inserted into a mouthpiece 11 and the end of the light guide 12 and is fixed to the mouthpiece 11 by a set screw 15 screwed to the mouthpiece 11. The laser light 7 oscillated by a laser oscillator 6 is condensed by the light guide 13 of the light guide 12 and is coupled to the incident end face 4a of the optical fiber 4. Coupling of the laser light 7 to the incident end face 4a of the optical fiber 4 is thereby permitted without making positional adjustment in the X, Y and Z directions.

Abstract: PROBLEM TO BE SOLVED: To conduct optical communication at a low error rate independently a location of the optical communication equipment. SOLUTION: A plurality of light receiving elements PD1-PD5 placed in different directions in the optical communication equipment 23 receive individually an external optical signal. A comparator circuit 43 discriminates a level of a luminous quantity signal from a specific light receiving element connected via a changeover circuit 42, a demodulation circuit 34 demodulates a discrimination signal denoting a discrimination result to obtain a reception data signal.
