Title: Variable valve timing control device for internal combustion engine
Inventor: KADOWAKI HISASHI
IPC: F02D41/04
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To improve the learning precision of the reference position of a cam shaft and precisely control the actual cam/crank shaft phase difference by calibrating the apparent cam/crank shaft phase difference by use of the learnt value corresponding to the present operating area. SOLUTION: The apparent cam/crank shaft phase difference is detected by the relative rotating angle between the crank shaft phase detection pulse signal from a crank shaft sensor 20 and the cam shaft phase detection pulse signal from a cam shaft sensor 19 generated subsequently. Thereafter, the learnt value of maximum lag position is subtracted from the apparent cam/crank shaft phase difference to calculate the actual advance, and a target advance is calculated from a map or the like according to the engine rotating speed and intake pipe pressure at that time. Thereafter, a phase different regulating device 18 is controlled so that the actual advance of an intake side cam shaft 17 is coincident to the target advance.  When the lag position learning condition is established, the learnt value of maximum lag position is learnt and renewed every operating area divided by the engine rotating speed and intake pipe pressure.

Title: Signal processor for electromagnetic pickup
Inventor: SUGIMURA KIYOSHI
IPC: G01P3/488
Filed: 1987-09-21
Abstract: PURPOSE:To achieve a higher detection sensitivity at a high frequency area of an electromagnetic pickup, by selecting an electrostatic capacity C of a capacitor as C=1/L (2pif0)<2> (wherein f0: max. of frequency and L: inductance of electromagnetic coil). CONSTITUTION:With the rotation of a rotor 10, an electromagnetic pickup 20 generates an induced voltage from an electromagnetic coil 23 and an capacitor 31 generates a filter voltage to compute a rotational speed of the rotor 10 with an arithmetic circuit 32 based on the filter voltage. Here, an electrostatic capacity C of the capacitor 31 is selected as C=1/L(2pif0)<2>. In this case, when the rotational speed of the rotor 10, namely, the frequency of an induced voltage is in a low rage, the filter voltage changes almost in proportion to the rotational speed. As the rotational speed of the rotor 10 increases, the frequency of the induced voltage grows toward the max. f0 and the filter voltage increases almost in proportion to the rotational speed of the rotor 10 covering from a low to high range of frequency. This achieves a higher detection sensitivity in a high frequency area of the electromagnetic pickup.

IPC: B28B1/52
Filed: 1990-09-06
Abstract: PURPOSE: To provide a cement mixture that is much densified and has especially an excellent bending strength, by mixing reinforcing fibers to a paste formed by mixing a prescribed amount of a first pulverized material whose average grain diameter is specified, water and an additive to cement.  
     CONSTITUTION: A paste is prepared by mixing per 100 parts by weight of cement, approximately 5 to 20 parts by weight of a first pulverized material, of which the grains have an average diameter of between 1/5 and 1/10 of the average diameter of the grains of the cement and approximately 20 to 35 parts by weight of water. The paste is then mixed with reinforcing fibers of a kind or over whose average diameter is approximately 3 to 30 μm to obtain the cement mixture including the reinforcing fibers. Furthermore, several kinds of reinforcing fibers are introduced to the cement. That is, mineral fibers or glass fibers whose average diameter is approximately 10-30 μm and those of the same type whose average diameter is approximately 5 μm are added to the mixture. In this case, the 1st fibers are used to improve the mechanical properties (elasticity, tensile strength, shock resistance) of the composite and the 2nd fibers are used to improve the impermeability and the resistance to very small cracks and wear.

Title: Ring anchor installing device
Inventor: INOUE MITSUHIRO
IPC: H01K3/10
Filed: 1990-09-10
Abstract: PURPOSE:To automate without converting the total length of a filament and to prevent the inclination of a ring anchor by holding the winding of the ring anchor between the coil-form filament element wires. CONSTITUTION:A core wire 22 to which a filament is wound is inserted to a mandril 21 to form a ring. And the lower end of the core wire 22 is grasped by a chuck 19 installed rotatable to an up and down movement plate 17, and the core wire 22 is maintained vertically. In this case, a wire material W for a ring anchor is cut in a specific length, and the cut wire material is wound to the mandril 21 for a ring and the filament to form the ring anchor while giving a tension. Since the core wire 22 is rotated by maintaining in the vertical direction in such a way, the winding of the ring anchor can be formed accurately. And since the wire material W cut in a specific length is wound while giving a tension, the wire material is put in securely between the element wires of the filament, and the filament is held rigidly.

IPC: G01F23/00
Filed: 1984-11-09
Abstract: PURPOSE:To detect a molten metal surface with high accuracy by determining the intersected point of the characteristic straight line between the buoyancy determined by the specific gravity of slag when a heat resistant float arrives at the slag layer on the molten metal and immersion depth and the characteristic straight line determined by the specific gravity of the molten metal when said float arrives at the molten metal.

The values of Ln and Bn are inputted to a processing unit 20. The unit 20 calculates the Bn-Ln characteristic straight line (the 1st buoyancy reference straight line) determined by the specific gravity of the slag until the float 16 arrives at the molten metal surface 14 from the point P1 when the float arrives at the slag surface 11, then the unit calculates the Bn-Ln characteristic straight line (the 2nd buoyancy reference straight line) determined by the specific gravity of the molten metal during the immersion of the float into the molten metal from the values of Ln and Bn inputted successively to said unit and detects the molten metal with high accuracy from the intersected point of both straight lines.

Title: System for varying power feeding current for optical fiber cable system
Inventor: OGURA YOICHI
IPC: H04B10/80
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To simplify and facilitate system-up by shifting the inclination resistance of a power feeding characteristic with a prescribed step in the increase direction of a constant current setting value when a power feeding voltage becomes lower than a prescribed voltage lower limit value, which is decreased by the constant current operation of a power feeding device in an opposite station when the current setting value of the power feeding device in one's own station in a constant current operation state is increased. SOLUTION: The step control circuit 6 of the power feeding device in a power feeding current varying system gives a step current command to a slope control circuit 4 when a detection voltage from a voltage detector 3 becomes lower than the lower limit value of the power feeding voltage which is decided by the power feeding characteristic. The control circuit 4 shifts the inclination resistance of the power feeding characteristic in the direction by which the current setting value is increased by a prescribed amount degree by a step current command, gives the current command to a current control circuit, which is slope-controlled concerning the detection voltage based on the inclination resistance, and controls a constant current power feeding circuit 1. Thus, the power feeding current is increased while executing the constant current operation in one's own station.
