Title: Epoxy resin curative
Inventor: SAIMURA FUMITAKA
IPC: C08G59/62
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To obtain an epoxy resin curative which exhibits a high curing capability in curing an epoxy resin and gives a cured item having a low stress and excellent resistances to heat and moisture by using a polyhydric phenol as the main ingredient. SOLUTION: This curative contains 20-80 wt.% polyhydric phenol of formula I (wherein R is 1-8C alkyl; and m is 1 or 2). The alkyl group represented by R in the formula is methyl, ethyl, n-propyl, i-propyl, n-butyl, sec-butyl, t-butyl, t-octyl, etc., methyl being esp. pref. since it gives the highest crosslink density in curing. The positions of R's on the central alkylphenol ring in formula I is such that the bonding of two phenol molecules to the central alkylphenol through an aldehyde is not hindered, i.e., the positions are 2- and 3-positions, 2- and 5-positions, or 2-, 3-, and 5-positions. The polyhydric phenol of formula I is synthesized by using an alkylphenol of formula II as a starting material.

IPC: G11B20/18
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To easily and effectively improve the decoding reliability by outputting the decoding reliability flag information that indicates a code series area having high possibility of wrong decoding decision processing following a decoding code string if the likelihood difference that is checked in the maximum likelihood decision processing of each decoding code series is smaller than a prescribed standard. SOLUTION: A maximum likelihood sequence decoding circuit 308 inputs a receiving signal series 107 and then generates and outputs a decoding code series z(k) having the maximum likelihood and a decoding reliability flag 123 corresponding to each code position. A decoding code candidate block list generation circuit 309 refers to a substitute code string that is previously set on the basis of the code position indicating the flag 123. Based on this referring result, a decoding code candidate block selection circuit 313 detects a fixed decoding code string 127 out of a set where the circuit 309 substituted the code string set on the string z(k) of a prescribed relative position. As a result, the decoding error code can be effectively corrected after the maximum likelihood sequence is detected.

Title: Single crystal optical fiber
Inventor: YOKOHAMA ITARU
IPC: G02B6/00
Filed: 1988-05-25
Abstract: PURPOSE:To facilitate the adjustment of phase matching conditions by impressing an electric field to the optical fiber in the direction perpendicular to the axial direction thereof, thereby drastically changing the refractive index of lithium niobate. CONSTITUTION:Aluminum electrodes 12 are deposited on the side faces of the single crystal optical fiber 1 along the axial direction of the single crystal optical fiber so as to sandwich the side faces thereof from the optical axis direction of the crystal and the direction opposite thereto. Potentials V1, V2 are respectively impressed to these aluminum electrodes 12. The single crystal optical fiber 14 is formed by heating a crystal rod of the lithium niobate by a CO2 laser and pulling up the same in the form of a fiber. Since the lithium niobate is an electrooptic crystal, the refractive index thereof is changed by the electrooptic effect when the electric field is impressed thereto. As a result, the refracted light of ordinary light and extraordinary light can be so adjusted as to satisfy the phase matching relation.

     SOLUTION: Scraps of WC, W and a W-contg. material are oxidized at ≥700°C to form tetragonal octahedral WO 3  insoluble in water and an ammonia soln. This WO 3  is reduced to WO 2  with hydrogen and this WO 2  is reoxidized at a low temp. to form monoclinic WO 3 . This WO 3  is dissolved in an ammonia soln. to prepare an ammonium tungstate soln., which is then spray-dried, and the resultant powder is carburized to produce a precursor compsn. for forming WC. Cobalt contained in the scraps is converted from metal Co into tungstate and then converted into an ammine complex soluble in the ammonia soln.
