Title: Anomaly diagnostic system of internal combustion engine
Inventor: MORINAGA SHUJIRO
IPC: G01M15/04
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To improve the precision of anomaly diagnostic based upon the output of air-fuel ratio sensors. SOLUTION: An air-fuel ratio sensor 28 of a limiting current type is placed in an exhaust pipe 26 of an engine 11. From the voltage variation ΔV and current variation ΔI that occur when voltage application to the air-fuel ratio sensor 28 is changed over to the positive or negative direction, the element impedance Z, or ΔV/ΔI, is computed as alternative data to the element temperature. An element impedance Z lower than the impedance, for example 60 Ω, that corresponds to the lower bound of the temperature range of complete activation is a criterion of decisions that the air-fuel ratio sensor 28 is in a completely activated state. While the air-fuel ratio sensor 28 is found in a completely activated state, its output is used for the anomaly diagnostic of the fuel supply system and the like.  No anomaly diagnostic is thus permitted while the air-fuel ratio sensor 28 is in a partially activated state with the result that the precision of anomaly diagnostic is improved.

IPC: G01P1/08
Filed: 1980-01-18
Abstract: PURPOSE:To accurately display a vehicle speed as well as to easily read it by a method wherein a time space to update the display content of a digital indicator is controlled by means of a magnitude of acceleration speed and a magnitude of travelling speed of a vehicle. CONSTITUTION:A display control circuit 18 controls a time space to update the display content of a digital indicator 8 by means of the magnitude of a voltage signal from a regulating speed detection circuit 9 indicating a regulating speed and the magnitude of a voltage signal from a F/V converter 2 indicating a detection vehicle speed. This display control circuit 8 consists of comparators 19, 20 which discriminate the magnitude of the voltage signal from the regulating speed detection circuit 9, comparators 21, 22 which discriminate the magnitude of a voltage signal from the F/V converter 2 and a change-over circuit 23 which outputs any of clock signals from an oscillator 3' corresponding to binary level of output signals from the comparators 19-22, to a latch circuit 5 as a latch signal.

Title: Healthy instrument
Inventor: NAGASE NOBORU
IPC: A61H7/00
Filed: 1989-01-10
Abstract: PURPOSE:To execute a massage without any control by a user by equipping the subject instrument with the first driving means to move a seat back and forth under an approximately horizontal state and the second driving means to keep the reciprocating direction of the seat in the horizontal state and change the direction. CONSTITUTION:When a back is to be massaged, the back is placed on a seat 21, a head part is placed on one fixing base A, and a leg part is placed on the other fixing base A. On the other hand, a velocity adjusting dial 31 of a controller 29 is previously set so that the seat 21 can move back and forth at a desired velocity, a direction changeover switch 33 is set to either an X direction or a Y direction, and a mode changeover switch 32 is set. When a power 30 is turned on, the seat 21 moves back and forth in the X direction at the set velocity by the driving of a tilting motor 12. Further, when the reciprocating direction of the seat 21 is to be changed, it is enough to switch the direction changeover switch 33 of the controller 29 to the Y direction. Thus, the direction in which the seat 21 massages the back can be changed only by operating the controller 29, and it becomes unnecessary for the user to stand up, etc.

Title: Anomaly detection system of rotary signal
Inventor: TAKAHASHI TAKANORI
IPC: F02D45/00
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To determine whether rotary signals involve an anomaly by measuring the time intervals between reference position signal detection and gap-toothed position detection and correcting the measured time intervals with occasionally momentary engine speeds. SOLUTION: An intake camshaft 21 and an exhaust camshaft 22 are drive- coupled to a crankshaft 23 via a timing belt 24 so as to make one turn every two turns of the crankshaft 23. A reference position sensor 26 is opposite a cam rotor 25, and a rotational angle sensor 28 is opposite a crank rotor 27. The reference position sensor 26 outputs reference position signals every 720 deg. crank angle, and the rotational angle sensor 28 outputs rotational pulse signals every 10 deg. crank angle, during which it detects a gap-toothed portion 27b every 360 deg. crank angle. The intake camshaft 21 is associated with a phase adjustment type VVT mechanism 29.  An ECU 30 measures the time intervals between the detection of reference position signals and the detection of gap-toothed positions and corrects the measured time intervals with occasionally momentary engine speeds and with the phase advancement the VVT mechanism 29 provides for the intake camshaft 21, to thus determine whether the rotary signals have an anomaly or not.

Title: Magnetic recorder and track access system
Inventor: MARUYAMA TAKAO
IPC: G11B21/10
Filed: 1988-01-11
Abstract: PURPOSE:To obtain a high seed accessing and a mass capacity by combining a continuous track seeking executed in a smaller area than a pitch of a multi- track magnetic head element and a step-like seeking executed at broader cycle than the whole. CONSTITUTION:When a servo head element 90 is positioned at the center between servo tracks 901 and 902, data head elements 10-80 are positioned at data tracks 101-810 relatively. The elements 10-80 are positioned at the ajoining data track sequentially attending with the shift of the element 90. After the element 90 is positioned the center between tracks 910 and 911, the elements 10-80 are positioned at the tracks 110-810 relatively. When the track access of a multi-track magnetic head 1 is made, a positioning error to generate the remarkable increase of a crosstalk or the increase of an error rate is not recognized, and a seeking time is extremely short. Thus, accurate positioning accuracy and a high speed track access are attained, recording density is increased remarkably, and the throughput of information can be increased.

Abstract: PURPOSE: To obtain a thickening and shape-retaining agent capable of giving good ductility and malleability, good plastic fluidity, and good shape retentin to products by using a thermally denatured guar gum of a specific swelling property.  
     CONSTITUTION: A thermally denatured guar gum of a swelling degree of 4W10ml, preferably 6W9.5ml, is obtained by heating natural guar gum powder or guar seed split at 80W200°C, preferably 110W180°C, grinding, denaturing to a desired swelling degree, and screening it as needed. The thickening and shape-retaining agent thus obtained is resistant to change in properties even at high temperatures, and its bean odor has been removed. Further, it is not denatured chemically and thus is suitable for foods in particular. The foresaid swelling degree is measured by the procedure in which 0.1g of sample is accurately weighed in a test tube, 10ml of an aqueous solution containing 26% ammonium chloride and 10% zinc chloride are added to the test tube, the test tube is stirred and heated for 5min on a boiling water bath, and then the content is transferred to a 10ml mess cylinder and then allowed to stand at 25°C for 24 hours to measure the volume (ml) of precipitated portion.

Title: Apparatus for supplying hot water
Inventor: WATANABE TOSHIYA
IPC: F23J15/00
Filed: 1991-01-18
Abstract: PURPOSE:To make an apparatus supply hot water marked by accelerated warming and good warmth after bathing as an effect of rich carbonic acid gas while ensuring high safety, high efficiency enabling a reduction of the fuel cost, cleanness of the exhaust gas, and pleasantness of the stabilized supply of hot water by a method wherein water is heated by direct contact with exhaust gas from combustion and in an apparatus designed to keep water from falling on the means for the combustion. CONSTITUTION:A flame is produced from a means for combustion 6 toward a combustion chamber 7 below. On the other hand, water is fed from a water- delivery part 10 through an exhaust passageway 9 branching off from the side of the combustion chamber 7. This water undergoes exchange of heat directly with the exhaust gas from the combustion, which is discharged through the exhaust passageway 9, and the heated water is supplied through a hot-water storage chamber 8 provided below the combustion chamber 7 and a through hot-water supply pipe 13. Since water is kept from falling on the means for combustion, there is no possibility of a failure in ignition or extinguishing of the flame during operation. This method makes carbonic acid gas in the exhaust gas dissolve in the hot water.
