Title: Magnetic head
Inventor: SUGITA SHINYA
IPC: G11B5/265
Filed: 1986-04-14
Abstract: PURPOSE:To decrease the distance between an R/W gap and an erasure gap by winding an erasure coil generating an erasure magnetic field inverse to each other to the two erasure cores as one set clipping the R/W core. CONSTITUTION:A current flows to the erasure coils 22, 32 at data recording and an erasure magnetic flux is generated in the erasure cores 20, 30. In flowing a current to the erasure coil 22 and the other erasure coil 32 to generate a reverse erasure magnetic field to each other, the induced magnetic flux 43a generated in the R/W gap 11, that is, the R/W core 10 is canceled by the said magnetic flux. Since the residual magnetic flux region on the medium has the same size as shown in regions A1, B1, the reproduced signal waveform at read is vertically symmetrically, resulting that the peak shift is decreased. Thus, the gap between the R/W gap and the erasure gap is decreased.

Title: Chemically amplifying resist
Inventor: YAMANA SHINJI
IPC: C08K5/00
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To obtain a resist for far IR rays having improved durability for storage after exposure and an improved pattern profile by preparing the resin by amide coupling of a cyclic carbon having high transparency for far IR rays and excellent etching durability for the base resin. SOLUTION: This chemically amplifying resist consists of a base resin and a photoacid producing agent, and the base resin consists of a resin produced by amide coupling of a cyclic carbon having high transparency for far IR rays and excellent etching durability. Since the chemically amplifying resist used has carbonyl groups and amino groups as polar groups in the resin structure, the resist has good adhesion property with a Si substrate having silanol groups having rather high polarity on the surface. The amino groups in the resin structure trap the acid produced by exposure and suppress diffusion of the acid. Thus, the obtd. resist for far IR rays has improved durability for storage after exposure and a pattern profile.

Title: Voice recognition circuit using estimate of phoneme
Inventor: JIYON PII KUREEKAA
IPC: G10L15/00
Filed: 1988-04-08
Abstract: PURPOSE: To increase a calculation time used for pattern recognition of a data reduction display of a received voice by using a phoneme estimation unit generating estimation enabling a process for discriminating a spoken word or phrase. CONSTITUTION: For example, a speech signal in the form of the output of a microphone is received by the phoneme estimation unit 12. At an arbitrary point of time, the phoneme estimation unit 12 outputs a group of outputs, and each output is obtained from tolerance constituting the phoneme that a speech received each time corresponds to the output, which is defined as 'estimation'. A word/phrase decision unit 14 receives the estimation, inquires of a library 16 for words and phrases listed in the form of constituent phonemes to exclude phonemes having small tolerance from an object, and decides which word and phrase are accepted. Consequently, the calculation time which is used to recognize one pattern is increased without increasing the time needed for the entire process of the speech recognition.
