Title: Electromagnetic induction-type probe
Inventor: WAKAMATSU HIDEKI
IPC: G01R27/26
Filed: 1995-02-23
Abstract: PURPOSE: To propose a means which prevents a loop current generated by the electromagnetic induction from being diverted to stray capacitance in an electromagnetic induction-type probe measuring electric properties of a solution, particularly reduce errors when a dielectric constant is measured. CONSTITUTION: A part of an electromagnetic induction current induced by an electromagnetic induction-type probe to a sample solution is diverted to stray capacitance constituted of dielectrics in the probe. The diverted current reduces a current interlinking with a secondary core, thereby giving rise to errors in the measuring value of capacitance components of the sample solution, namely, dielectric constant. Therefore, a structure wherein an annular primary core 10, a secondary core 12 and other composing elements of the probe are made concentric in cross section is constituted thereby generating an electric field 31 by the excitation of the primary core 10 concentrically in the primary core and secondary core. Components of the electric field in a direction of a normal of sectional circles of the cores are eliminated.  Accordingly, a current flowing in the sample solution is prevented from being diverted into the probe.

CONSTITUTION: An additive color-type multicolor thermal recording material consists of a substrate and a plurality of thermal recording layers forming colors of different tones by different thermal energies on the substrate. A high-temperature color-forming recording component or both a high-temperature color-forming recording component and a low- temperature color-forming recording component are encapsuled in polymeric heat-response microcapsule wall films responding to different thermal energies. A recording material producing a light color is used for the low-temperature color-forming thermal recording layer and a recording material producing a thick color is used for the high-temperature color-forming thermal recording layer.  The low-temperature color-forming thermal recording layer and the high-temperature color-forming thermal recording layer can be structured in one layer, but color-separation properties can be further improved by structuring the low-temperature color-forming thermal recording layer and the high-temperature color-forming thermal recording layer in two layers.

Title: Fuel cut control method for gasoline engine
Inventor: SUEMATSU TOSHIO
IPC: F02D41/34
Filed: 1984-03-28
Abstract: PURPOSE:To simply suppress knocking and prevent an abnormal rise of the exhaust temperature by changing the predetermined maximum delay angle quantity to the larger maximum delay angle quantity and also cutting the fuel feed under a specific condition. CONSTITUTION:The ignition timing of a gasoline engine is controlled with the predetermined maximum delay angle quantity as the upper limit (P1) using the fuel with a predetermined octane value. When the octane value is low (P0), the predetermined maximum delay angle quantity is changed to the larger maximum delay angle quantity (P2). When the rotation speed (P3) and load (P4) of the engine become predetermined values or higher, the fuel feed to the gasoline engine is cut (P5). Accordingly, knocking can be suppressed by using the fuel with different octane values, and an ill effect due to the exhaust temperature rise can be preveted.

Abstract: PURPOSE:To enable tracking of a non-heat emitting substance by a method wherein a color image signal whose R, G and B components approximate to reference colors is extracted, the color components are synthesized, a luminance average is determined on the basis of the synthesized components and tracking of a target is conducted in accordance with the order of luminance averages. CONSTITUTION:The color image of a target is sensed by a color image sensor element 11 supported by a stabilized gimbal 16, and a color extracting element 12 extracts only signals of colors approximating to reference colors from R, G and B signals from the sensor element 11 and outputs a synthesized image signal. A gate being applied to this signal, a luminance average computing element 13 calculates a local average value of luminance with respect to all images. Then, an order processing element 14 selects several average luminance images having large average values and supplies informations on positions thereof to a tracking signal output element 15. The gimbal 16 is controlled by a tracking signal given from the output element 15 on the basis of said informations, and thus the target of a non-heat emitting substance can also be tracked since a heat wave is not used.
