Title: Carrier for immobilizing actic protein
Inventor: IKEDA MIKIO
IPC: B01J20/26
Filed: 1982-08-23
Abstract: PURPOSE:To obtain an artificial carrier which enables a highly sensitive detection of antibodies or the like, by a method wherein amino groups of gelatin are crosslinked with an aldehyde in a mixture of gelatin, water-soluble polysaccharide and metaphosphate ion to form a specified spherical particle for use in the immobilization of an active protein such as antigen. CONSTITUTION:After controlling the pH of a mixture comprising 1-15wt% gelatin, 0.5-8wt% water-soluble polysaccharide such as gum arabic, 0.05-3wt% metaphosphate ion and 70-90wt% water, which further contains, if necessary a pigment, a surfactant and the like, the amino groups of the gelatin are crosslinked with an aldehyde-based crosslinking agent to form a hydrophilic and non- soluble particle with the size of 1-100mu in which the polysaccharide and metaphosphate ion have been electrostatically bonded to the gelatin. The particle thus obtained provides an electrophoretic mobility of -1.1--0.8mu/sec/V/cm in a 0.15M phosphate-buffered saline solution of pH 7.2 at 25 deg.C. This affords a carrier for use in the immobilization of active protein, such as antigen, which is optimal for a highly sensitive detection of antibody or the like.

Title: Time data generator
Inventor: MURAKAMI HIROIKU
IPC: H04N5/93
Filed: 1992-05-11
Abstract: PURPOSE:To generate time data of changing values in turn in simple operation processing by previously deciding whether a drop frame exists in continuous frames or not and changing for a renewal value based on a result of this decision and then renewing the time data. CONSTITUTION:The time data stored in a register is given to a DF detecting circuit 28, where the frame immediately before a drop frame is detected. When a magnetic tape is reproduced in the normal reproducing direction in response to an adding operation changeover signal F/R, and when an operation result is rised at a value of 1 by executing the operation processing, the following frame is decided as the drop frame and the decision result is outputted to an adding value generating circuit 36 by the circuit 28. Adding values are changed by the circuit 36 based on the signal F/R and an operation result of the circuit 28, and when there is no drop frame at the time of reproducing in the normal direction, a prescribed adding value is outputted. When the following frame is the drop frame, the adding value is changed and outputted.

Title: Internal-combustion engine with divided cylinder group operation control type
Inventor: UENO MAKOTO
IPC: F02D17/02
Filed: 1981-09-16
Abstract: PURPOSE:To attain smooth emission of exhaust gas even at the time of switching the number of operative cylinders, by keeping a predetermined air-fuel ratio through accurate measurement of the quantity of intake air supplied to cylinders irrespective of whether an intake-air stop valve is opened or closed. CONSTITUTION:A first cylinder group A is connected to a first intake manifold 11 and a first exhaust manifold 14, while a second cylinder group B is connected to a second intake manifold 12 and a second exhaust manifold 15. When the engine operation is switched from high-load operation to low-load operation, an intake-air stop valve 26 is closed gradually to its half-opening position. The quantity of intake air to be supplied to the first cylinder group A is calculated by subtracting the quantity of intake air to be supplied to the second cylinder group B from the total quantity of intake air that is detected from the output signal of an air-flow meter 25, and fuel is injected to cylinders so that the air- fuel ratio of mixture supplied to the cylinders is kept at the theoretical air-fuel ratio.

Title: Power detector
Inventor: HIROHATA YUKITOSHI
IPC: G01R21/133
Filed: 1993-06-16
Abstract: PURPOSE:To enable the detection of effective power even in the case of not only a three-phase alternating current but also a single phase alternating current by providing a voltage detector for checking to see if an input is the single phase alternating current or the three-phase alternating current. CONSTITUTION:A zero-cross detector 1 detects any one 0V of an analog voltage signal inputs VRS, VST and VTR. A PLL circuit 2 latches a voltage V0 and divides the frequency thereof by 64 to output a voltage VPLL. A/D converters 3a and 3b convert the signals VRS, VST and VTR and analog voltage input signals IR, IS and IT into digital signals. A digital signal processor 4 performs a control and a power computation. A voltage detector 6 converts alternating current to direct current for each phase and outputs '1' when the potential of the direct current is larger than a reference potential. The voltage detector 6 allows the detection for checking to see in what phase an input signal exists in the case of a single phase. An analog multiplexer 7 outputs an input VRS in the direction of a three-phase power and a voltage in the phase detected with the voltage detector 6 in the case of a single phase.

Abstract: PURPOSE:To form a superconducting circuit having large current gains by connecting a predetermined superconductor by another superconductor having an energy gap larger than the energy gap of the predetermined superconductor. CONSTITUTION:The title element consists of an injector composed of a superconductor 30, a tunnel barrier 31 and a superconductor 32, an acceptor made up of the superconductor 32, a tunnel barrier 33 and a superconductor 34 and an input terminal 35, an output terminal 36, a grounding 37, a superconductor 38 and connections 39, 40.
