IPC: H05B33/14
Filed: 1989-06-05
Abstract: PURPOSE:To reduce power consumption by setting the grain size distribution range of phosphors in a light emitting layer to + or -5-30% centering the most grain size and the thickness of the light emitting layer to 30-70mum. CONSTITUTION:The grain size distribution range of phosphors in a light emitting layer 5 is set to + or -5-30% centering the most grain size, and the thickness of an insulating layer 4 is set within the range 30-70mum. When the grain size of phosphors is small, power consumption is made small, but the life is made short. When the thickness of the light emitting layer 5 is large, power consumption is made small, but luminescence intensity is reduced. When the thickness of the insulating layer 4 is large, power consumption is made small, but luminescence intensity is reduced. When the grain size of phosphors and the thickness of the light emitting layer 5 are limited as above, both effects are obtained, and power consumption can be reduced without reducing luminescence intensity.

Abstract: PURPOSE:To prevent lowering of grindability and generation of finishing unevenness by starting grinding after a shape of a grinding face of a grinding body is formed into a stable grinding face in accordance with a rolling roll diameter, an eccecntric amount and tilted face, etc. CONSTITUTION:In the case of using new cup-shaped grinding stones 3 as a grinding body for on-line grinding of a rolling roll 2, the grinding face of the stone 3 is previously formed into a stable grinding face 3a having a profile (m2) and then grinding is started.

IPC: G11B5/39
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To suppress the change of the anisotropic magnetic field of a free layer and the reduction of the rate of change in MR based on it, when magnetization directions of upper and lower magnetic layers between which a nonmagnetic layer is interposed are made to be in an orthogonal relation in a spin valve type magnetoresistance effect element.

Title: Quality inspecting method for join part
Inventor: HIEDA TAKU
IPC: G01N21/88
Filed: 1989-06-06
Abstract: PURPOSE:To easily discriminate between a normal and a defective part by sinking a join body, formed by joining a join body which can transmits light with an opposite join body, in liquid whose refractive index is closer to that of the join body than that of air and observing the reflection state of light on the join surface. CONSTITUTION:A pressure sensor 1 consists of an Si chip 5 and a pedestal 6 made of glass and the periphery of the chip 5 is anode-joined with the upper end surface of the pedestal 6. The sensor 1 is sunk in a water tank 3 with the pedestal 6 up. When the join surface 1a of the sensor 1 in the water tank 3 is irradiated with light from a light source 2, the light reflected by the join surface 1a travels into the water from the glass. At this time, the water is smaller in difference in refractive index from the glass than the air, so the light reflected by the join surface 1a travels in nearly the same direction when entering the water from the glass. Therefore, scattering can be suppressed even when the flank of the pedestal 6 is rough and frosted. Consequently, if there is a defective part in the join surface 1a when the light reflected by the join surface 1a is observed through a microscope, even a fine defective can be detected.

Abstract: PURPOSE:To prevent a fixed image part from being falsified, by a method wherein an adhesive layer comprising a specified particulate copolymer resin is provided between a base and a thermal color forming layer. CONSTITUTION:An adhesive layer comprising a resin mixed with a particulate styrene/methacrylic acid copolymer resin is provided between the base and the thermal color forming layer.

Abstract: PURPOSE:To obtain a low strength mild steel wire having coarse grains of <=2 in the crystal grain size number for a mild steel wire by subjecting the steel wire rod contg. C, Si, Mn and Al respectively at prescribed rates and contg. Al/N at a regulated ratio to drawing at a prescribed reduction of area or above then heating the wire rod up to a specific temp. region thereby annealing the wire rod. CONSTITUTION:A steel wire rod contg., by weight %, <=0.04% C, <=0.1% Si, 0.1-0.6% Mn and 0.005-0.030% Al and having the relation 2.5<=Al(%)/N(%) <=7.5 is manufactured.

Title: Aluminum titanate sintered compact and its production
Inventor: FUKUSHIMA YASUMASA
IPC: C04B35/46
Filed: 1993-06-15
Abstract: PURPOSE:To obtain an aluminum titanate sintered compact improving mechanical strength and thermal expansion history without damaging the high melting point and low coefficient of thermal expansion which are original strong points by sintering the aluminum titanate as the starting material within a specified temp. range. CONSTITUTION:The aluminum titanate as the starting material is sintered within the range of 1100-1400 deg.C to give the aluminum titanate sintered compact. The sintered compact has <=2/10<6> deg.C average coefficient of thermal expansion in 20-1000 deg.C, and the sintered compact consists essentially of the aluminum titanate. The sintering temp. less than 1100 deg.C is improper because sufficient mechanical strength is not obtained because pores during sintering unreasonably increase due to insufficient sintering and also the coefficient of thermal expansion becomes large. On the other hand, when the sintering temp. is over 1400 deg.C, the mechanical strength becomes low and the hysteresis of thermal expansion history becomes large because of many crackings present in the sintered compact. Therefore, the sintering temp. is set to 1100-1400 deg.C.

Title: Color image pickup device
Inventor: AKIYAMA TOSHIYUKI
IPC: H04N9/07
Filed: 1988-06-13
Abstract: PURPOSE:To improve the vertical color resolution by adopting the structure where picture elements are arranged in two-dimension in the unit of 2 picture elements longitudinally and 3 picture elements laterally. CONSTITUTION:A filter is used, which has a structure that picture elements are arranged in two-dimension in the unit of 2 picture elements longitudinally and 3 picture elements laterally, and filter elements are constituted so that a determinant of a prescribed matrix obtained from coefficients of three sum signals being sums of signals from two longitudinal picture elements, (C1+C4), (C2+C5) and (C3+C6) is not zero in order to obtain all R, G, B signal levels even if elements able to output sum signals of the longitudinal two picture elements only are employed. Thus, a luminance signal, a red color signal and a blue color signal are obtained from signals of the same horizontal period only entirely. That is, the period of the color signal in the vertical direction is the repetition of the 2 longitudinal picture elements. Thus, the vertical color resolution is improved.
