Title: Optical disk library device
Inventor: OKUMURA NOBUYOSHI
IPC: G11B17/22
Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To obtain a library device which detects the presence or absence of all the optical disks in a short time without taking out trays by resolving the problem that it takes a long time to confirm all slits in a conventional method where a carrying unit is moved to each slit and optical disks are pulled out one by one to perform confirmation because it is necessary to discriminate whether an optical disk is stored in each slit in an optical disk storage rack or not at the time of initialization of many optical disks stored in the optical disk storage rack. SOLUTION: Windows 4a and 4b are opened in both side faces of an optical disk storage rack 1b. Two arms 14 extended from a carrying unit 5 to windows 4a and 4b are provided. A light emitting element 6a and a light receiving element 6b are provided in the front end of one arm 14 and that of the other arm 14 respectively so that their heights may be different by an extent corresponding to one slit and light connecting both elements may cross the surface of an optical disk through windows 4a and 4b, The carrying unit continuously confirms the light reception signal of the light receiving signal 6b while moving, thereby detecting the presence or the absence of optical disks.

Abstract: PROBLEM TO BE SOLVED: To provide a high tensile strength steel excellent in toughness in a very large heat input weld heat-affected zone in the case of heat input of >=200 kJ/cm (e.g. even of the order of 1,500 kJ/cm). SOLUTION: This steel contains two or more kinds among MgO, MgS, and Mg (O, S) of 0.005 to 0.5 μm grain size by (1.0×10<5> to 1.0×10<7> ) pieces/mm<2> . This steel has a composition containing, by weight, 0.04-0.2% C, 0.02-0.5% Si, 0.6-2.0% Mn, <=0.02% P, 0.003-0.01% S, <=0.01% Al, 0.0002-0.005% Mg, and 0.0005-0.005% O, also containing, as selective elements, 0.005-0.025% Ti and 0.002-0.008% N, further containing, as selective elements, proper amounts of one or >=2 elements among Cu, Ni, Cr, Mo, Nb, V, and B, and contg. the balance Fe with inevitable impurities. By the pinning action of the fine grains of MgO, MgS, and Mg (O, S), γ-grain growth in the very large heat input weld heat-affected zone can be inhibited and toughness in the HAZ can be improved. This effect can be increased to a greater extent by precipitating TiN on MgO.

The TDMA terminal station to receive the frequency instruction changes the frequency and goes to the waiting state to as to receive a designated TDMA base station. Consequently, all subscriber connecting edges can be accessed to the arbitrary time slot for the calling of an arbitrary carrier. Thus, an equalizer is eliminated and the number of terminal stations capable of accommodation can be increased.

Title: Wafer alignment apparatus
Inventor: KARITA YUTAKA
IPC: H01L21/68
Filed: 1983-06-13
Abstract: PURPOSE:To prevent the abrasion of particular area and improve durability by changing the area where wafer is in contact with the roller. CONSTITUTION:Since a sleeve 7 engaging with a stepping bolt 6 is fixed to a slide part 5, it moves to the right and left along a horizontal bar 4 of mechanism 3 by the rotation of stepping bolt 6 and a bearing 10 fixed to the sleeve 7 moves to the right or left. When the bearing 10 moves to the right or left, a rubber roller 9 axially supported by the bearing 10 moves to the right or left and thereby the position where the wafer 1 is in contact with the roller changes. Moreover, when the rubber roller 9 is rotated by an external motor 11a, any influence is not given on the rotation of stepping bolt and sleeve, owing to the sliding of bearing. The stepping bolt can be driven by a pulse motor, etc. Movement to the right or left of rubber roller causes the whole of the alignment apparatus to move downward and prevents damage of wafer and generation of dust when operated under the condition that the roller is separated from wafer.

Title: Preparation of threonine
Inventor: KOBAYASHI IWAO
IPC: C07C229/22
Filed: 1982-06-21
Abstract: PURPOSE:To prepare the titled compound easily in high yield, by reacting glycine with acetaldehyde in a basic medium in the presence of less than stoichiometric amount of a metallic compound capable of forming a glycine-metal complex. CONSTITUTION:Threonine is prepared by reacting glycine with acetaldehyde or a compound which forms acetaldehyde under the reaction condition (e.g. paraldehyde, vinyl acetate, etc.) in a basic medium (e.g. NaOH/methanol) in the presence of a metallic compound capable of forming a glycine metal complex (e.g. hydroxide of copper-group metal). The amount of the metallic compound is less than the stoichiometric amount to form the glycine complex. Although the stoichiometric amount depends on the metal, there is no limitations on the amount of the metallic compound provided that it is smaller than the stoichiometric amount, and preferably it is 0.001-0.9 times the stoichiometric amount. Since the amount of the metallic compound is small, the cost and labor for the recovery and separation of the compound and the disposal of the waste water can be saved.
