Title: Surface treatment of magnesium alloy
Inventor: TAKAHASHI HIROSHI
IPC: B05D5/00
Filed: 1993-03-31
Abstract: PURPOSE:To surface-treat a magnesium alloy at low equipment and production costs and with the chipping resistance improved. CONSTITUTION:A ceramic is electrodeposited on the surface of a magnesium alloy 1 to form a ceramic layer 6. Since the ceramic is nonconductive and is an electrolytic material, a charge is transferred to the alloy 1 or the bubbles generated by the oxidation-reduction of the ceramic is conducted, and innumerable pores 9 are formed in the ceramic layer 6. Accordingly, a coating material is applied on the ceramic layer having the pores 9 to form an intermediate coating layer 7, and a part of the coating material forming the intermediate coating layer 7 intrudes into the pore 9 and is solidified. Consequently, the coating material constituting the intermediate coating layer 7 is firmly attached to the ceramic layer 6 with the solidified part in the pore 9 as an anchor 10.

Title: Fuel control device
Inventor: SHIMOMURA SETSUHIRO
IPC: F02D41/18
Filed: 1986-04-25
Abstract: PURPOSE:To prevent wrong fault judgement to output lowering of an inlet air amount sensor by detecting fault of the inlet air amount sensor by its output, and stopping detection of the fault until the output of the inlet air amount sensor becomes the predetermined level. CONSTITUTION:An ECU 10 determined fuel injection amount based on respective signals from an AFS (inlet air amount sensor) 2, a crank angle sensor 11, starting switch 13, engine cooling water temperature switch 13 and a throttle sensor 4, and controls the pulse width of fuel injection pulse of an injection 9 by synchronizing with the signal from the crank angle sensor 11. And when all the burnoff conditions are established, the ECU 10 generates burnoff control signal 14. In this case, the fault is detected by the output level of the AFS 2. And after the burnoff control is finished, operation of the fault detecting unit is stopped until the output of the AFS sensor 2 reaches the predetermined level.

Title: Purity evaluation method and apparatus for metal
Inventor: TAKEUCHI EIICHI
IPC: G01N27/74
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To enable stably discharging of impurities onto the surface of molten metal by a method wherein a DC magnetic field is applied superposingly to the molten metal in addition to an AC magnetic field generated by a water-cooled induction coil and the fluidization of the metal is inhibited to prevent re-entraining of the impurities. SOLUTION: A sample metal 9 is placed in a circumferentially split water-cooled metal crucible 5 and when a high frequency current from a high frequency oscillator 6 flows through a water cooled induction coil 8, an induction current encircling each segment flows to the crucible 5. Therefore, the induction current flows through the sample 9 to melt it by induction heating and the currents flowing through the melted sample 9, the crucible 5 and the coil 8 mutually interact to inwardly push the melted sample 9 by a repulsive force. As the cross section of the crucible 5 is made smaller to the bottom thereto. a repulsive force works being more intense to the bottom so that the sample 9 floats in the crucible 5 to eject impurities onto the outer circumference of a floating body.  A DC magnetic field 18 acts on the whole of the sample 9 by a DC coil 22 to inhibit the fluidization of the molten metal attributed to the AC magnetic field and a heat distribution. This minimizes the re-entraining of the impurities ejected once onto the surface.

Title: Wire dot head
Inventor: MIZUNO SHIGEKI
IPC: B41J2/25
Filed: 1988-04-20
Abstract: PURPOSE:To prevent the intrusion of ink into a head even when a hollow printing wire is used, and to manufacture the title head excellent in reliability and durability by sealing both ends or another end of the hollow printing wire. CONSTITUTION:A projecting section 2a is formed to a joining section with a printing wire 1 of an armature 2, and the printing wire 1 is abutted against the projecting section 2a of the armature, and fixed through brazing. Consequently, a solder material creeps between a fixing end with the armature 2 of the printing wire 1 and the projecting section 2a of the armature 2, and constitution in which the hollow section of the printing wire 1 is closed completely is shaped. As a result, intrusion into a head through the hollow section of the printing wire of ink during printing is prevented. Accordingly, the behavior of the armature is stabilized, and the corrosion of the sliding section of the armature, etc., due to the chemical action of ink and the damage of durability are obviated. Since the printing wire with the hollow section is used, the printing wire is lightened, and the speed of the head can be increased naturally.
