Title: Membranous el display element
Inventor: MIMORI KENICHI
IPC: G09F9/30
Filed: 1987-08-08
Abstract: PURPOSE:To prevent a seizure phenomenon even when an asymmetric wave driving is executed by doping an insulating layer with phosphorus. CONSTITUTION:In a membranous EL display element which is composed by laminating a transparent electrode 2, an EL (Electroluminescence) luminous layer 4, insulating layers 3 and 5 holding the luminous layer 4, and an opposite electrode 6 on a transparent substrate 1, the insulating layers 3 and 5 are doped with phosphorus.

Title: Magnetic recording and reproducing device
Inventor: OKAMURA FUJIO
IPC: G11B5/588
Filed: 1983-10-26
Abstract: PURPOSE:To attain stable tracking control in a postrecording mode by fixing the frequency of bias current so that pilot signal frequency for tracking control is interleaved between the frequency of voice erasing bias current and its higher harmonic frequency. CONSTITUTION:A voice processing circuit 28 having a means for fixing frequency to the frequency nFH of bias current supplies bias current IA, IB fixed to the frequency nFH to a voice erasing head 40 and a voice recording/reproducing head 41. In the postrecording mode, magnetic flux based upon the bias current IA, IB is jumped into rotary video heads 5, 6. However, the frequency difference between the reference frequency nfH of bias current IA, IB or higher harmonic frequency 2nFH and the frequency of a pilot signal is 1+ or -0.5fH-3+ or - 0.5fH even in the worst case, so that there are no fH and 3fH components. Therefore, the frequency components based upon the bias current IA, IB are sufficiently attenuated by band-pass filters 31, 32 and stable tracking control in the postrecording mode can be attained.

Abstract: PURPOSE:To obtain a protective coating material for annealing capable of improving the magnetic characteristics of an anisotropic silicon steel plate by adding a small amount of fine metallic powder of Al, Si, Ti, Cr, Zr or the like to magnesium oxide. CONSTITUTION:A protective coating material for annealing for an anisotropic silicon steel plate is obtd. by adding 0.1-10wt% fine metallic powder of >=1 kind among Al, Si, Ti, Cr, Zr, Nb, Sn, W and Mo to magnesium oxide. A slurry of the coating material is applied to a silicon steel plate after decarburization annealing and dried to remote the water. The steel plate is annealed at high temp. in a gaseous mixture of H2 with N2 to cause secondary recrystallization, and impurities in the steel is removed in an H2 atmosphere to obtain an anisotropic silicon steel plate. The oxidation of the steel plate during the annealing at high temp. is inhibited by using the protective coating material for annealing, so an anisotropic silicon steel plate with stable magnetic characteristics can be manufactured.
Patent JP-H0485094-A (JP)
Title: Valve apparatus
Inventor: HORI JIRO
IPC: B43K8/02
Filed: 1990-07-30
Abstract: PURPOSE:To certainly operate a valve apparatus under low pressure in a low flow rate with high accuracy by pressing a valve head part to a valve seat surface by the shrinkage of a synthetic resin material forming a valve disc at the time of curing and forming a gap for the flow of a fluid between the outer peripheral surface of a valve stem part and the inner peripheral surface of a valve stem insertion hole. CONSTITUTION:When the silicone rubber constituting a valve disc is cured, slight shrinkage is generated. Therefore, a valve stem part 12b is also shrunk in its axial direction and, by this shrinkage, a valve head part 12a is pressed to a valve seat part 11a under predetermined pressure. Since the valve stem part 12b is also shrunk in its diameter direction, a gap 20 is formed between the outer peripheral surface of the valve stem part 12b and the inner peripheral surface of a valve stem insertion hole 11b as an ink flow passage. When the difference pressure between an ink storage chamber 2 and an auxiliary ink chamber 6 reaches a predetermined value or more, the valve stem part 12b slightly extends by this pressure and a slight gap is formed between the valve head part 12a and the valve stem part 11a and the valve apparatus becomes an open state to allow ink to flow to the auxiliary ink chamber 6. When the pressure in the auxiliary ink chamber 6 becomes high, the valve apparatus acts as a check valve to prevent the back flow of the ink.

Title: Cutting tool and its manufacture
Inventor: ARAI TATSUO
IPC: B23P15/34
Filed: 1991-08-08
Abstract: PURPOSE:To provide a cutting tool whose surface hardness is high and whose durability is superior and which is of high precision and which is inexpensive. CONSTITUTION:A chip fitting groove 2a, a center hole 9, a boss surface 10 and the like are formed at a tool main body 1, and then, a hardened layer is formed by administering nitrification treatment over the whole surface of the tool main body 1. It is recommended that hardness at the hardened layer be made to be over Hv500 at a 0.1mm position from the tool surface. It is also recommended that the boss surface 10 and the inner periphery surface of the center hole 9 be made to be ground surfaces from which soft films produced by nitrification treatment are removed. It is desired that the chip fitting groove 2a be made to be a bare surface which has no finish processing after nitrification treatment, and it is also desired that the screw hole inside formed at the main body 1 be made to be a nitrification preventive portion. As a result, hardness necessary for the tool is given by means of the hardened layer due to nitrification treatment. As distortion is hard to occur at the time of nitrification treatment, precision can be maintained even if finish processing is not administered after treatment.
