IPC: C08G69/10
Filed: 1995-02-23
Abstract: PURPOSE: To produce and recover a polyaspartic acid having high purity in an easy manner at a low cost in a short time by forming a polyaspartic acid salt from a polysuccinimide and subsequently reacting the salt with an acid to neutralize it. CONSTITUTION: This method comprises the following processes: (A) a polyaspartic acid salt is formed by reacting a polysuccinimide having a degree of polymerization of 10-2000 with a base to convert the imide ring to the salt of an amic acid; (B) a polyaspartic acid and a salt are formed by reacting the polyaspartic acid salt with an acid to convert the salt of the amic acid to an amide; and (C) the polyaspartic acid is separated from the salt and recovered by adding a mixed solvent of water with an organic: solvent to the mixture of the polyaspartic acid with the salt and making the salt dissolve in the mixed solvent and precipitate the polyaspartic acid or by making the polyaspartic acid dissolve in the mixed solvent and precipitate the salt by controlling the balance of hydrophilic nature/hydrophobic nature of the mixed solvent.  The base used in the process A is preferably a basic amino acid or its salt.

In the Frensnel lens, a lens in which many grooves are arranged in a concentric shape and whose cross-sectional shape is made to be a saw shape is preferable and a lens in which depths of grooves are in the range 10-100μm is preferable.  Since the influence of light scattings becomes innegligible when depths of grooves are not larger than 10μm and boundary parts of grooves become conspicuos when the depths of the grooves are not lower than 1000μm, a lens in which depths of grooves are not in the range 10-1000μm is not preferable.

Title: Manufacture of semiconductor laser device
Inventor: TAKEMOTO AKIRA
IPC: H01S5/00
Filed: 1987-02-18
Abstract: PURPOSE:To restrict the height of a mesa part to a small range, make a stable oscillation of transversal mode possible, and increase the efficiency, by making the impurity concentration of at least one of a buried layer and a second current blocking layer high. CONSTITUTION:One or both of the P-type second current blocking layer 5 and the P-type buried layer 6 are made impurity concentration high, and a crystal is grown. After the crystal growth, the high concentration impurity in the P-type current blocking layer 5 and the P-type buried layer 6 is diffused into a first current blocking layer 4. Accordingly, a part of region 7 in the vicinity of a mesa part in the N-type first current blocking layer 4 is inverted to P-type, and finally a semiconductor laser device of buried type hetero structure (BH) is formed. Thus the height of mesa part can be low, while the width of an active layer 2 is kept sufficiently narrow. A stabilized oscillation of transversal mode can be realized, and further an operation of high efficiency is available, thereby.

Title: Aligner
Inventor: NEI MASAHIRO
IPC: H01L21/027
Filed: 1991-02-07
Abstract: PURPOSE:To reduce a position measuring error due to a temperature rise in, a stage and to reduce a position measuring error caused by the fluctuation of the air due to the movement of the stage by a method wherein the stage is provided with a reflecting mirror for a laser interferometer used to measure the relative position of an object to be exposed and a venthole is made in the reflecting mirror or in its support part. CONSTITUTION:Ventholes 101a to 101c are arranged in an X-axis reflecting mirror 3a; ventholes 101d to 101f are arranged in a Y-axis reflecting mirror 3b. When an exposure action is started a wafer stage is warmed up and its temperature is raised by heat generated from individual V-F guide parts 60a, 60b in the wafer stage and from a nut or the like screwed to a drive-system feed screw 20. When the heat is transmitted from an X-stage 6x and the temperature of the reflecting mirrors 3a, 3b is raised, the face accuracy of a mirror face 30 is worsened and a measuring error at a laser interferometer is caused. Since the ventholes exist in the reflecting mirrors, a heat-dissipating area is expanded as compared with that in conventional cases. As a result, a temperature rise rate is reduced and a measuring error due to a temperature change is reduced.
