Title: Method for calculating color value in color image recorder
Inventor: SCHIELKE RAINER
IPC: H04N9/07
Filed: 1999-08-10
Abstract: PROBLEM TO BE SOLVED: To obtain high image quality by interpolating a color value of each pixel based on a color value of a same kind detected from a plurality of pixels placed on each occasion in a pixel surrounding area through low pass filtering to correct color slurring. SOLUTION: Original color values R0, G0, B0d of a pixel detected by the image recorder 9 are given to color channel interpolation stages 11R, 11G, 11B acting like a low pass filter via a color channel changeover device 10, from which color values RTP, GTP, BTP that are low-pass-filtered are produced and fed to a differential forming stage 12, where differences DR, DG, DB with respect to the original color values R0, G0, B0 are formed. Then difference DR, DG, DB that are processed by high pass filtering and include only contour lines of image information are given to color channel adder stages 13R, 13G, 13B, where they are selectively added to the color values RTP, GTP, BTP to obtain color values R, G, B whose sharpness is compensated. The color values R, G, B are tentatively stored in a color value memory 14 for succeeding processing.

Title: Method for measuring concentration of adenosine 5'-diphosphate and enzyme activity of enzyme forming adenosine 5'-diphosphate
Inventor: MIZUTANI FUMIO
IPC: C12Q1/00
Filed: 1983-11-29
Abstract: PURPOSE:To measure the concn. of adenosine 5'-diphosphate (ADP) and the enzyme activity of enzyme forming ADP by using an enzyme electrode having two kinds of immobilized enzyme; immobilized pyruvate oxidase and immobilized pyruvate kinase. CONSTITUTION:An immobilized pyruvate oxidase film 2 and an immobilized pyruvate kinase film 3 are fixed on the surface of an oxygen electrode or hydrogen peroxide electrode 1 to constitute an enzyme electrode. A prescribed amt. of sample is added from a supply pipe 9 to a buffer soln. 3 in the case of measuring the concn. of ADP in the sample. ADP and phosphenol pyruvic acid are diffused in the film 3 to form a pyruvic acid. The pyruvic acid is diffused and oxidized in the film 2 and in this stage said acid consumes oxygen and generates hydrogen peroxide. The hydrogen peroxide is detected by the change in the current of the electrode 1. The intended enzyme substrate is added preliminarily to the buffer soln. and the similar measurement is performed in the case of measuring the enzyme activity of the enzyme forming the ADP in the sample.

Title: Mixing circuit
Inventor: SATO MASAHARU
IPC: H03D7/12
Filed: 1988-09-09
Abstract: PURPOSE:To reduce the intermodulation distortion by inputting an RF signal to a common emitter of a differential circuit only through a capacitor so as to form a V-I conversion circuit with an excellent linearity. CONSTITUTION:Current sources I1, I2 are coupled individually to the 1st differential circuits Q1, Q2 and the 2nd differential circuits Q3, Q4 and the RF signal is inputted directly to the common emitter of the 1st differential circuits Q1, Q2 and the 2nd differential circuits Q3, Q4. A current flowing to the emitter of the 1st differential circuits Q1, Q2 has a change proportional to the input signal and the change in the current depends on the total sum of the signal source impedance, the impedance comprising a resistor R5 and a capacitor C1 and the impedance in the common emitter of the differential circuits. As the signal source impedance including the the resistor R5 and the capacitor C1 is high, the current distortion in the V-I conversion is less. Thus, the intermodulation distortion is reduced.

Title: Separate display method of water and fat spectrum in mri apparatus
Inventor: MIURA NOBUYUKI
IPC: G01N24/08
Filed: 1991-09-09
Abstract: PURPOSE:To enable separate display of both water and fat spectrums by sampling an echo signal at a timing at which a phase difference in magnetization vector between a water spectrum and a fat spectrum to have a real part of a complex data obtained after a Fourier transform either in a water or fat spectrum. CONSTITUTION:An echo signal is sampled from an object to be inspected at a timing at which a phase difference gives pi/2 between a magnetization vector MW of a water component and a magnetization vector MFR of a fat component. The echo signal sampled undergoes a Fourier transform and a real part alone of a complex data obtained is plotted as a graph to be shown on a display device. The graph gives a spectrum confined only to the water component. A false part of the complex data is plotted as a graph to be shown on the display device. The graph obtained gives a spectrum confined only to the fat component. This enables displaying a water spectrum and a fat spectrum independently and separately.

Filed: 1992-08-27
Abstract: PURPOSE:To reduce the vibration transmitting from a low temperature generation part to electronic element by providing mounts for the low temperature generation part of a freezer and a Dewar so as to keep the both forming small gap between them. CONSTITUTION:In order not to directly contact a low temperature generation part 6 of a freezer 3 and a Dewar 2, a mount 12 for low temperature generation part and a mount 13 for Dewar with metal for example, are provided to keep both forming a specified gap in between. The mount 12 and 13 are fixed to a structure part 14 of metal for example, respectively. When the freezer 3 starts operation and low temperature starts to be produced at the tip of the cold finger 7 of the low temperature generation part 6, the surrounding air is liquefied in the small gap between the cold finger 7 and the inner shell bottom plate 11 of the Dewar 2 and an electronic element l is cooled via the liquefied air accumulated there. As they are operated without contacting the low temperature generation part 6 and the Dewar 2, the electronic element 1 can be cooled without transmitting vibration from the low temperature generation part 6 directly to the Dewar 2.

Title: Photosensitive body for electrophotography
Inventor: TSUTSUMI MASAHIRO
IPC: G03G5/00
Filed: 1982-12-25
Abstract: PURPOSE:To provide high sensitivity and to inhibit reduction in the surface potential due to repeated use by dispersing a charge generating pigment in a charge transferring medium contg. silicone oil in a specified weight ratio to polyvinylcarbazole resin so as to enable the uniform dispersion of the pigment. CONSTITUTION:Silicone oil is added to a charge transferring medium contg. polyvinylcarbazole resin as the principal component by 0.1-10pts.wt. per 100pts. wt. polyvinylcarbazole resin, and a charge generating pigment is dispersed in the medium. A perylene pigment represented by the formula [where each of R1 and R2 is H, (substituted) alkyl or aryl] is preferably used as the charge generating pigment. Since the added silicone oil improves the wetting property of the pigment, the pigment is uniformly dispersed in the medium, and the adhesive strength of the surfaces of the pigment particles to the medium is improved. Accordingly, a photosensitive body having high sensitivity and a long life is obtd. Charges are hardly accumulated in the photosensitive body even when electrostatic charge and exposure are repeated, and reduction in the surface potential is prevented.
