Title: Magnetic powder and magnetic recording medium
Inventor: TETSUKAWA HIROKI
IPC: C09D5/23
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic recording medium which exhibits excellent weathering resistance and low electric resistance. SOLUTION: In a magnetic layer 4, the surface of metal magnetic powder is mechanochemically covered with carbon black. Thereby oxidation on the surface of the metal magnetic powder can be prevented. Since the surface of metal magnetic powder is mechanochemically covered with the carbon black whose electric conductivity is high, electric resistance is reduced.

Title: Fuel injection system for internal combustion engine
Inventor: KOJIMA AKIKAZU
IPC: F02M47/00
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To decrease discharge amount of nitrogen oxide (NOx) by reducing the initial injection rate without entailing any drop in control responsiveness, in this accumulator fuel injection system for an internal combustion engine. SOLUTION: An effective area of a passage 17 in the midway of releasing the pressure of fuel to the side of low pressure via a low pressure oil path 16 and a control valve, from a control chamber 8 to be formed on top of a control piston 9 connected to a needle, is decreased according to a rise in this control piston 9. Since a groove 18, where depth is varied, is formed in a projection 9b installed in top of the control piston 9, this projection 9b is advanced into the passage 17 simultaneously with the ascent of the control piston 9, an effective area of the groove 18, turning to a substantial passage, is gradually decreased.  As the effective area of this groove 18 is large enough before the start of fuel injection, if the control valve of the low pressure oil path 16 is opened, the control piston 9 quickly goes up and injection is started without any time delay, but an injection rate is first held down to lowness, and subsequently it is slowly increased, so that such a pilot injection as being effective for a reduction in nitrogen oxide (NOx) is made possible to be done.

Title: Hydraulic transfer print simulation software
Inventor: NAKANE SHINICHI
IPC: B44C1/175
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To obtain a computer-readable recording medium which can display the condition of transfer print results about a product that should be subjected to a hydraulic transfer print by displaying the decision results of each triangular polygon separately or synthetically on the display. SOLUTION: A hydraulic transfer print simulation program executes vertex coordinate data input (processing 1) of a triangular polygon and carries out the change (processing 2) of a work attitude into a vessel entering angle. And, it parallelly performs the decision (processing 3 and 4) of an air pocket, the decision (processing 5 and 6) of inflow and the decision (processing 7) of film thickness. The synthetic (processing 8) of each decision about these decision results and the output (processing 9) of the results are successively carried out. Thus, the condition of transfer print results in a simulation process can be shown on a display through the program operation by a computer even without actually attempting a hydraulic transfer print process using a prototype about a product or a prototype which is subjected to the trial of hydraulic transfer print.
