Filed: 1992-11-11
Abstract: PURPOSE:To suppress the generation of an internal strain and a working strain and to execute pressing with high precision by pressing a stock to be press- punched with the pressing value beyond the elastic limit value. CONSTITUTION:A value G1 is set which is beyond an elastic limit value G of a stock 10 to be press-punched and within a range of a press deformation or a press breakage (G1>=G).

Title: Cleaning agent and cleaning method for soft contact lens
Inventor: NOZAWA MEGUMI
IPC: C11D17/00
Filed: 1987-12-23
Abstract: PURPOSE:To prevent hardening and flawing of a lens after cleaning by incorporating a water-miscible nonaq. pasting agent into a cleaning agent at 50-20wt.% of the total amt. of the cleaning agent and incorporating the fine particles of a water soluble compd. which has <=0.65 salt value and specific grain size therein at 50-80wt.%. CONSTITUTION:An increase in osmotic pressure by dissolution of the fine particles in water is prevented by using the compd. having <=0.65 salt value and the dehydration from the lens by a nonaq. solvent is prevented by forming the cleaning agent into a paste form. The easy tendency of the lens to flawing and the lowering of the cleaning effect by rapid dissolution of the fine particles in water are prevented if the particle size is in the range where the 100% of the particles pass the JIS standard sieve of sieve #100 and >=50wt.% do not pass the JIS standard sieve of sieve #635. Namely, buff consisting of a porous sponge sheet is moistened and the cleaning agent paste is placed thereon and is uniformly spread, then the nonaq. pasting agent is diluted by the moisture of the hydrous buff. Generation of a problem such as hardening of the lens is thereby prevented even if the hydrous soft contact lens is rubbed and cleaned on the buff.

Abstract: PURPOSE: To provide the Japanese analyzing device and Japanese text speech synthesizing device which decreases words judged as unregistered words in a Japanese text. CONSTITUTION: A preprocessing part 201 roughly divides the inputted Japanese text. A word identification part 202 detects words, which can not be indentified even by retrieving a word dictionary 203, as unregistered words in the roughly divided text. A dictionary relooking-up part 205 retrieves the word dictionary 203 by using the readings of the unregistered words detected by the word identification part 202 and finds and outputs 'reading information' (information consisting of reading, accent type, connection information, parts of speech, etc.) on the unregistered words to the word identification part 202. The word identification part 202 once inputting the 'reading information' on the unregistered words determines information on the reading, accent, pause, etc., of the input Japanese text on the basis of the input information finally.  A speech synthetic part 206 synthesizes a speech of the Japanese text on the basis of the information on the reading, accent, pause, etc., of the Japanese text inputted from the word identification part 202.

Title: Data protecting circuit
Inventor: TATENO SUMIO
IPC: H04L1/08
Filed: 1989-12-15
Abstract: PURPOSE:To reduce the capacity of a memory not by writing input data to the memory but by counting how many times either '1' or '0' continuously comes. CONSTITUTION:A data protecting circuit is composed of a memory 1, adder circuit 2, comparator circuit 3, clear circuit 4, decode circuit 5 and select circuit 6. The decode circuit 5 detects the required number of times for the continuous '0' or '1' and under the control of this detection signal, either the input data or the circulating data of the memory 1 are selected. Then, the detection data of the continuous coincidence are outputted from the select circuit 6. Thus, in the conventional data protecting circuit, as the capacity of the memory, 17 bits X the number of lines is required. However, in this circuit, 8 bits Xthe number of lines is enough as the capacity of the memory. Then, the capacity of the memory to be used can be reduced.
