Title: Catalytic temperature controller for internal combustion engine
Inventor: ITO YASUSHI
IPC: F02B23/10
Filed: 1990-11-28
Abstract: PURPOSE:To restrain a catalytic temperature from lowering even if exhaust gas temperature goes down by feeding evaporating fuel gas into an engine intake passage at a time when the catalytic temperature is in a constant temperature range setting the allowable minimum catalytic temperature down to the lower limit value. CONSTITUTION:A temperature sensor 10 detects a catalytic temperature in a catalytic converter 9 installed in an engine exhaust passage. In addition, a purge controller 12 controls a supply of evaporative fuel gas into an intake duct 4. In this case, an electronic control unit 30 feeds the evaporative fuel gas into the intake duct 4 at a time when a detected value of the temperature sensor 10 is in a constant temperature range, setting the allowable minimum catalytic temperature capable of controlling the emission gas, down to the lower limit value. With this constitution, since the evaporative fuel gas is conducted up to the catalytic converter 9 and oxidized, such a fear that the catalytic temperature goes down is restrained from occurring even if exhaust gas temperature is lowered.

Title: Code information presenting method and device applying same method
Inventor: KOZUKA YOJI
IPC: G06K19/06
Filed: 1991-10-03
Abstract: PURPOSE:To provide a communication equipment as well as an information processor which can read the code information with no use of the reflected light by securing a constitution where the light and darkness of the transmitted light can serve as the code information. CONSTITUTION:In regard of a bar code, for example, the light emitted from a light source 1 passes through a bar code display plate 2. These transmitted light and dark beams 3 are led to a lens system 4 and therefore can be projected in the prescribed width. Under such conditions, the code information can be electrically varied with use of a liquid crystal display that has especially high light transmissibility. Otherwise the code information is projected on a CRT display and then radiated through the system 4. In this case, the code information projected on the display can also be electrically varied. Furthermore it is possible to acquire the color code information with use of the liquid crystal display or a CRT. That is, if a certain code shows a digit '3', the different types of information can be presented in the red and white colors, for example, even with the same code.

Title: Combustion state detecting device for internal combustion engine
Inventor: INAGAKI HIROSHI
IPC: F02P17/12
Filed: 1995-11-17
Abstract: PURPOSE: To enable the misfire of all the cylinders in an internal combustion engine using a bipolar distributor-less ignition system to be detected properly. CONSTITUTION: When a high voltage is generated on the secondary side of an ignition coil 26, it is applied to positive and negative spark plugs 52, 54 to cause a spark discharge, and a first capacitor 42 is charged therewith. The first capacitor 42 then applies voltages to the positive and negative spark plugs 52, 54 between which the spark discharge has ceased. If the cylinder is in an ignition cycle and normal combustion has taken place inside the cylinder, the voltage applied to the positive spark plug 52 is attenuated because a current is made to flow between the center electrode and the outside electrode of the positive spark plug 52 by ions generated during the combustion. Based on the attenuation characteristic of the voltage, a misfire detecting circuit 49 detects that the normal combustion has taken place inside the cylinder.

Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To provide the high quality lamination type optical disk in which the increase in double refraction is minimized and no deterioration in the signal characteristics is observed even when the hardening speed of an adhesive is accelerated or dust and air bubbles are trapped or in a high speed rotation. SOLUTION: One information signal surface L1 and a reflection film 2 are formed on one surface of a substrate 1B. Moreover, the other information signal surface L0 and a semitransparent film 3 are formed on one surface of a transparent substrate 1A. Then, the substrates 1A and 1B are laminated together through adhesive 4 so that the surfaces L0 and L1 are made mutually opposite to each other. Thus, the one side two layer reproducing type optical disk is realized in which the information signals recorded on the surfaces L0 and L1 are read from the transparent substrate side.  In order to reduce the internal stress of the adhesive 4 generated during the laminating, the numerical value, which is defined by multiplying the photoelastic constant of the adhesive 4 and the film thickness together, is set to less than 2.0×10<-4> mm<3> /kg within the operating temperature range of the disk. Thus, the increase in double refraction is minimized even when the hardening speed of the adhesive 4 is accelerated or dust and air bubbles are inadvertently trapped or in a high speed rotation operation.

Filed: 1999-11-15
Abstract: PROBLEM TO BE SOLVED: To enable high-output magnetoresistive effect head and a memory element by a method wherein a magnetoresistive effect element is structured on at least one or all of magnetic layers by use of a film of which a main component is a specified substance of relatively high resistance. SOLUTION: A magnetoresistive effect element is composed of two oxide magnetic layers 1, 3 magnetically separated by a nonmagnetic layer 2, and is structured mainly by MFe2O4 (M is an element of one species or two species or more selected from Fe, Co, Ni). The oxide magnetic layers 1, 3 can be formed as the layers in which one is easy to magnetize and rotate due to an external magnetic field and the other is not, or one has a small coercive force and the other is not, by changing a film thickness or changing a composition. Thus, an angle between magnetization directions of two magnetic layers with respect to the external magnetic field changes, and the resistance changes corresponding thereto.  Accordingly, an electrode is provided in a lamination film, and a current flows, thereby obtaining a magnetoresistive effect element by reading, by a voltage change, a phenomenon that the resistance changes due to an external magnetic field.

Title: Disk device
Inventor: ITOI TETSUSHI
IPC: H04N5/85
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To realize an optical disk device for reducing the deterioration of a voice when an error is generated in reproduction data. SOLUTION: Data for a frame are constituted of a first half frame 71 and a second half frame 72. Picture data for each half frame are compressed and encoded by a compressing and encoding means, and a voice data dividing means 1 divides voice data corresponding to the picture data for one frame into even- numbered voice data sampled in the even-numbered turn and odd-numbered voice data sampled in the odd-numbered turn. A recording means makes a pair of the compressed picture data for the first half frame with the odd- numbered voice data, and makes a pair of the compressed picture data for the second half frame with the odd-numbered voice data, and records those pairs of data in different recording areas on a disk as a recording medium. Thus, even when any failure is generated in one half frame data, the voice data can be reproduced with the minimum interpolation length by using the other half frame.
