Title: High speed chroma converter for color picture
Inventor: KASANO AKIRA
IPC: G06T5/00
Filed: 1988-08-31
Abstract: PURPOSE:To perform the chroma conversion of a color picture at high speed and in addition, at high precision through the use of small-scale hardware by obtaining two kinds of matrix coefficients based on a given chroma conversion coefficient, and performing linear coupling operation. CONSTITUTION:The R, G, B components r', g', b' of a picture element concerned when the vector S in R, G, B color space of chroma components corresponding to the R, G, B components r, g, b of the same picture element is given to the chroma conversion S'-aS [(a) is chroma conversion coefficient] become a matrix expression I on condition that lightness is constant before/after the conversion. Then, two kinds of the matrix coefficients alpha, beta are obtained based on the given chroma conversion coefficient (a), and the linear coupling operation is performed by a linear coupling processor according to the expression I by using these alpha, beta and the R, G, B components r, g, b of the same picture element in the R, G, B picture memories. Thus, the chroma conversion of the color picture with less quantizing error can be performed at high speed through the use of small-scale system constitution.

Title: Manufacture of heat resistant magnetic scale
Inventor: ARA KATSUYUKI
IPC: C21D6/00
Filed: 1987-08-31
Abstract: PURPOSE:To obtain a heat resistant magnetic scale without deenergization even at a high temperature, by placing a material on a heat resistant substrate differing in the quality therefrom to mix the substrate with the material with the application of heat to the substrate together with the material. CONSTITUTION:A powder of magnetic material, for example, iron powder is applied on a plate-shaped non-magnetic stainless SUS 304 substrate 1, and then, when it is irradiated with a laser beam, the portion irradiation is melted rapidly by heat to fuse the iron powder into the stainless substrate. Subsequently, as the laser beam moves, the portion thus far irradiated is cooled rapidly to solidify. Thus, as subjected to a rapid solidification by cooling, the magnetic grating thus formed has an extreme residual stress force caused to generate a large residual magnetization by magnetization with a larger coercive force. This stabilizes this method as compared with the conventional type. Moreover, having the Curie point of more than 100 deg.C, a magnetic layer 2 provides a heat resistance without losing magnetism though exposed to a high temperature.

Title: Seat back construction
Inventor: NISHIYAMA KUNIO
IPC: A47C7/46
Filed: 1991-08-28
Abstract: PURPOSE:To obtain a seat back surface that fits the passenger's figure well and improve the comfort in sitting by a method wherein a bag is separated into left and right sides at the middle of a seat back and gas and particles filled in the bag move when the bag is pressed by the weight of a passenger. CONSTITUTION:Spaces between welds 23 and 25 inside a fitting mat 20 are separated into a number of chambers by a two or more separators 26, and spaces outside the welds 25 are separated into a number of chambers by separators 29. When the fitting mat 20 is pressed by the weight of a passenger, air 34 moves inside the chambers and between the second chamber B, the third chamber C,... and the Nth chamber N, and between the side first chamber X, the side second chamber Y and the side third chamber Z through through- holes 30, clearances 27 and through-hole 32. PE beads 36 can not pass the through-holes 30 as the PE beads have larger diameter than the through-holes 30, so that the PE beads 36 are retained between the front and back faces of the fitting mat 20. Therefore, the front face of the fitting mat 20 is prevented from contacting with the back face and is kept in a shape fitting the passenger's figure, and the comfort in sitting is improved.

CONSTITUTION:The operator of the diagnosing device inputs the name of the patient on an inspection instructing paper from an operating keyboard device 7 with either alphabet of HIRAGANA (cursive form of Japanese syllabary). Next, when the operator starts the device and presses a pushbutton to instruct the patient to do certain action, a voice synthesizing device 3 synthesizes the voice of the name of the patient based on the above-mentioned input data, and the synthesized voice is amplified in an amplifier 4 and vocalized from a speaker 5. Next, another voice to instruct the patient to do certain action, for example, 'stop your breath,' is vocalized in the same manner as that in a conventional device. For example, since the instruction is vocalized like 'Mr./ Mrs./Miss A, stop your breath' instead of the conventional instruction 'stop your breath,' the attention of the patient can be called.
