Title: Aluminum alloy hollow material and manufacture thereof
Inventor: TAGUCHI KAZUO
IPC: C22F1/00
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To prevent the preferential corrosion at a deposited portion by setting a value of the difference of electric conductivity at each part in the longitudinal direction of a hollow material to a specific value or lower, which is manufactured by executing a port hole extrusion to an Al alloy cast block containing a specific Mn content. SOLUTION: It is effective to beforehand precipitate Mn with a uniformizing treatment of the cast block containing at least 0.3-1.5 wt.% Mn and restrain the precipitation in the extrusion process thereafter in order to prevent the preferential corrosion at the deposited portion. The precipitated quantity of the extruded hollow material or the stretch reduction- extruded hollow material is regulated so that the difference of electric conductivity at each part of these hollow material becomes <=1.0 IACS%. This difference of electric conductivity is the difference between the max. value and the min. value of the electric conductivity of all samples cut into pieces in the longitudinal direction of the hollow material, and in the port holek-extuded material, the electric conductivity shows the min. at the extruded front top side and the max. at the rear end side.  The above uniformizing treatment is executed by holding the material at the prescribed temp. of 500-630 deg.C for 0-24 hr and thereafter, cooling down to the prescribed temp. of 400-500 deg.C at <=100 deg.C/h cooling speed and holding the material at this temp. for 4-48 hr.

Title: Fuel injection device
Inventor: OCHIAI MASAHIKO
IPC: F02M45/00
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection device for an internal combustion engine devised to restrain an initial injection rate without shortening a period of the maximum injection rate. SOLUTION: When pressure of a control room 81 is changed from high pressure to low pressure by a solenoid valve, fuel flows out to a low pressure side from a hydraulic chamber 88, differential pressure between the hydraulic chamber 88 and the control room 81 is generated, orifice members 82, 83 rise a shown in the drawing and a passage area of a valve flow passage part 87 to communicate the control room 81 and the hydraulic chamber 88 on the low pressure side to each other becomes small, and accordingly, lowering of pressure of the control room 81 is moderated. Consequently, an initial injection rate is restrained. Thereafter, when the passage area of the valve flow passage part 87 becomes large, pressure of the control room 81 is instantly lowered, and lift of a nozzle needle becomes the maximum.  When pressure of the control room is changed from low pressure to high pressure by the solenoid valve, high pressure fuel flows in the control room 81 from the hydraulic chamber 88, and injection shortage is sharply cut by quick pressure rise of the control room 81. Consequently, it is possible to make an injection rate at the time of fuel injection in steps.

Title: Japanese word processor
Inventor: SUZUKI SHUNICHI
IPC: G06F17/21
Filed: 1990-11-29
Abstract: PURPOSE:To improve the operability of a Japanese word processor by changing automatically the character space without correcting the character that controls the shift at the rear side of a table to be enlarged and then enlarging horizontally the table with no erasion of character. CONSTITUTION:An intra-line character string discriminating part 2 discriminates the digit number in a line, i.e., decides whether the digit number can be horizontally extended or not for the character positioned at the rear side of a table to be enlarged and controlled for the shift. If so, a table correcting part 4 is started end enlarges the table in the left column directly in the horizontal direction. If not due to a fact that the digit number has no margin for the character positioned at the rear side of the table, a character space adjusting part 3 is started end reduces the character spaces of the character string included in the right column of each line. Thus the operability of a Japanese word processor is improved.

Filed: 1999-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a pickup assuring the compatibility of an operation at the side of an optical disk driving device by allowing an output from the optical pickup to have roughly constant level with respect to optical disks having different reflectances. SOLUTION: A pickup 1 is constituted of a laser diode 2, a photodetector (signal transducer) 3 transforming a reflected light beam from an optical disk 10 into an electric signal and an amplifier 4 amplifying an electric signal posterior to the transformation. The amplifier 4 can vary its amplification factor by a control signal 5 to be generated in the circuit of the side of an optical disk driving device. When an optical disk having small reflectance is used in this optical dish driving device, the device transmits the control signal 5 to the pickup by detecting the reflectance of the disk based on a focus error signal at the time of performing focus search. Then, the amplifier 4 incorporated in the pickup changes its amplification factor by the control signal 5 from the optical disk driving device and the device can keep an output from the pickup constant.

Title: Production of solid electrolytic capacitor
Inventor: YOSHIDA MASANORI
IPC: H01G9/00
Filed: 1993-12-28
Abstract: PURPOSE:To realize high capacity with small size while reducing the leakage current by forming manganese dioxide even in micropores. CONSTITUTION:A cleaning process or a process for repairing an anodic oxidation film while applying a voltage is effected in a solution obtained by adding a surfactant to an aqueous solution containing water or an acid after manganese dioxide is formed on the anodic oxidation film formed on a porous electrode of valve metal (manganese dioxide forming process). Since the surfactant is left on the anodic oxidation film or the manganese dioxide, impregnation of manganese nitrate solution is accelerated. Consequently, manganese dioxide produced through thermal decomposition adheres to the entire surface of anodic oxidation film thus enhancing the coverage and thereby increasing the capacity. This method realizes a solid electrolytic capacitor having such characteristics as the quantity of manganese dioxide having function for repairing the oxide film increases at the interface between the oxide film and manganese dioxide thus decreasing the leakage current.

Filed: 1987-12-29
Abstract: PURPOSE:To make the capacity of a fuel pressure chamber inclusive of a fuel overflow passage too reducible by making an axis of a sliding hole in an overflow valve so as to be paralleled with a straight line almost orthogonal with that of a needle at some space. CONSTITUTION:A sliding hole 21 extending crosswise is formed in a housing body 1 at the sideway vicinity in a plunger hole 11. Accordingly, an axis of this sliding hole 21, where an overflow valve 22 is slidably inserted thereinto, is made so as to be paralleled with a straight line almost orthogonal with a common axis of a plunger and a needle 7 at some space. With this constitution, since the sliding hole 21 can be set up adjacently in a fuel pressure chamber 15, capacity of this fuel pressure chamber 15 inclusive of a fuel overflow passage 27 can be made smaller. Consequently, fuel pressure in the fuel pressure chamber 15 can be made into high pressure so easily, while the fuel pressure in the fuel pressure chamber 15 can be lowered at once when the overflow valve 22 is opened. In addition, breadth of a unit injection is narrowable.

Patent JP-H05263711-A (JP)
Title: Control circuit means for after-control of control system
IPC: G05F1/46
Filed: 1992-12-16
Abstract: PURPOSE: To switch off from the supply voltage without using a relay so as to reduce cost by terminating an after-control after the opening of an ignition switch by regulating the potential at the control input of a voltage regulator. CONSTITUTION: When the connection between a battery BA and a resistor R1 is interrupted by an ignition switch ZS, the On input side of a voltage regulator IC1 is continuously controlled by using the charge stored by a condenser C1 until the condenser C1 is discharged by the input voltage applied to the input side On of the voltage regulator IC1. During the time interval when the input side On of the voltage regulator IC1 is controlled, the voltage regulator supplies the supply voltage UVCC in a control system. After the potential of the input side On of the voltage regulator IC1 becomes lower, the voltage UVCC is not supplied immediately and the control system is shut off. Thus, the connection time of the after-control corresponds to the time needed until the condenser C1 is discharged. In this way, it is not necessary to use the expensive relay.
