Title: Optical recording medium
Inventor: SHIGEMATSU SHIGETO
IPC: G11B7/2433
Filed: 1990-03-07
Abstract: PURPOSE:To improve the ratio of the contrast between before and after irradiation of recording laser beams thereby to improve the C/N at the reproducing time of information by providing a recording layer containing Te, Ge and Zn with the ratio of atoms thereof set in a predetermined range. CONSTITUTION:An optical recording medium 10 is comprised of a substrate 3, a recording layer 2 formed on the surface of the substrate 3 and a protective layer 1 formed on the surface of the recording layer 2. The recording layer 2 is a thin film of an alloy containing Te, Ge and Zn, and which may include an element of a low melting point other than Te or the other components. Among them, Te-Ge-Zn alloy or an alloy mainly composed of Te-Ge-Zn is preferable. Since the recording layer contains Ge and Zn in addition to Te, the crystallization temperature of the recording layer becomes high, thereby improving the anti-oxidation property and durability of the optical recording body. Moreover, supposing that the ratio of atoms of Te, Ge and Zn in the recording layer 2 is expressed by (x) and (y) in (TexGe100-x)100-y Zny, 20<=x<=90 and 20<=y<=70 hold.

Inventor: ROOKENKIMU KIYUNHO
IPC: G06F17/30
Filed: 1990-03-07
Abstract: PURPOSE:To choose an input sentence or an input word in a short period out of a candidate lattice by calculating the differences of recognized distance among candidates, calculating the means value of these differences, calculating a search preference exponent accordant with the difference of recognized distances from the precedent candidate, and searching the candidates with preference in the order of smaller search preference exponents. CONSTITUTION:A processor 32 is provided together with a search processing part 33, a display 34, a keyboard 35, an input tablet 36, and a character recognizer 37. The difference of recognized distances is calculated between the candidate words, paragraphs or characters outputted from the recognizer 37. Then the mean value is calculated among the differences of recognized distances. Based on this average value, the search preference exponent is calculated in accordance with the difference of recognized distances from the precedent candidate for each candidate word, paragraph or character. Then these candidates are searched with preference in the order of smaller search preference exponents. Thus a correct input sentence or word is chosen, and the searching frequency is reduced. Therefore an input sentence or word can be chosen in a short period out of a candidate lattice.

Abstract: PROBLEM TO BE SOLVED: To provide a hand chisel also working as an air gun function by forming a branch path in the midway of a conducting path, and providing a jet nozzle for compressed air in the branch path through a shut-off valve. SOLUTION: When at first a shut-off valve 7 of a conducting path 2 is opened, and a shut-off valve 9 of a branch path 8 is closed, compressed air advances into a step part 6a of a piston 6 through a passing hole 11 and goes round to the rear end through a substantially L-shaped through hole 6b to make a piston 6 slide foward. The base end of the chisel 5 is stuck to apply energy to the pit of the tip. Secondly, with forward sliding of the piston 6, the through hole 6b is opened to a front chamber A through a partition wall 4. Whereupon, compressed air working on the rear end of the piston 6 is discharged from an air outlet 12 through the through hole 6b. Then, the compressed air is applied to the step part 6a so that the piston 6 is slid backward.  The shut-off valve 7 of the conducting path 2 is closed, the compressed air advances into the branch path 8 to be exhausted directly from a jet nozzle 10.

Abstract: PURPOSE: To reduce COD and make heavy metals insoluble to remove said metals by adding hydrogen peroxide and a solution of ferrous sulfate to the pickling waste liquor containing an inhibitor, copper ion sequestering agent and heavy metals, while controlling the pH.  
     CONSTITUTION: To the pickling waste liquor wich washes the piping of a boiler, heat exchanger, etc., and contains an inhibitor, copper ion sequestering agent, and heavy metals such as iron and copper, alkali is added firstly to adjust about 7.2W 7.5pH, which is weak alkaline. Then, hydrogen peroxide generating oxygen corresponding to the COD value of the waste liquor is added. Next, caustic alkali is added to adjust about ≥10pH and the solu. of ferrous sulfate is rapidly mixed to make the heavy metals insoluble, thereby settling the heavy metals. Thus, the heavy metals are treated by being made insoluble after COD is decreased by using iron ion in the waste liquor.

Title: Reaction method of solution or slurry
Inventor: OGATA TAKASHI
IPC: B01J3/00
Filed: 1984-03-26
Abstract: PURPOSE:To reduce the running cost of a high-pressure reaction by allowing the objective reactant in a soln. or a slurry which is charged into a high-pressure reaction vessel to react with a reactive gas while keeping the reactant to be always present in excess over the reactive gas. CONSTITUTION:A reactive gas is blown into a high-pressure reaction vessel while a soln. or a slurry is continuously forced into or discharged from the reaction vessel, and said soln. or slurry is allowed to react continuously with the reactive gas by contact under high pressure. Meanwhile, the reaction is carried out while keeping the objective reactant in the soln. or slurry to be present always in excess over the reactive gas. For example, when metallic sulfides are eluted by oxidation under high pressure, air, oxygen-enriched air, or pure oxygen are used as the reactive gas. In this case, the reaction rate of the gas or the oxygen efficiency is extremely increased, and hence the amt. of air to be forced into the autoclave can be sharply reduced. Accordingly, the power cost of a compressor necessary for compressing the air can be remarkably decreased.
