Filed: 1987-03-11
Abstract: PURPOSE:To improve corrosionproof performance, by forming a metallic film, which is produced from a specific material, on a surface of a magnet. CONSTITUTION:A metallic film, which is produced from metallic carbonyl M(CO)x (where M is one of V, Cr, Mo, W, Mn, Fe, Co, and Ni, and (x) is a numeral of 2 to 12 which is determined in accordance with a metallic element), is formed on a R2T14B group magnet whose main components are R-Fe-B (where R is a rare earth element containing yttrium, and T is a transition metal, and B is boron.) Namely, in a first process, after the magnet is soaked in a metal carbonyl liquid, it is heated for 1 to 60 min. at 200 deg.C to 800 deg.C in an atmosphere of a reducing or inactive gas and under reduced pressure of vacuum so that the metal carbonyl is decomposed. In a second process, while the magnet is heated at 50 deg.C to 800 deg.C in the atmosphere of the reducing or inactive atmosphere and under the reduced pressure of vacuum, metallic carbonyl vapor is introduced and the metal in the metallic carbonyl is precipitated uniformly on a surface of the magnet by vapor phase decomposition, and heat treatment of 200 deg.C to 800 deg.C is performed for 1 to 60 min. so as to form a metallic film, which is excellent in oxidation-proof performance, on the surface of the magnet. Thus, a permanent magnet with excellent oxidation proof performance can be obtained.

Title: Fuel injection device
Inventor: SHIRAISHI TAKASHI
IPC: F02D41/02
Filed: 1991-03-19
Abstract: PURPOSE:To stabilize exhaust performance and heighten the reliability of power performance by replacing stored information with the value recalculated by the output value of a fuel density sensor after fuel makeup upon detecting the execution of fuel makeup during the stop of an internal combustion engine. CONSTITUTION:Whether or not makeup fuel is supplied is judged by the sudden change of output from a tank fuel residual quantity sensor 7 serving as a fuel quantity detecting sensor or the change of information from a fuel tank change- over sensor. Upon detecting the change of information, the information of a fuel density detecting sensor 7 is obtained before performing fuel injection at the engine restarting time after fuel makeup so as to be reflected on a fuel correction factor at the restarting time. Accordingly, even in case the density of methanol is suddenly changed because of fuel makeup, an optimum mixture ratio can be provided immediately, which results in obtaining an internal combustion engine stable in exhaust performance and highly reliable in power performance.

Title: Drive device for multi-head type sewing machine
Inventor: TAJIMA IKUO
IPC: D05C11/06
Filed: 1995-03-14
Abstract: PURPOSE: To eliminate a need for a clutch mechanism every sewing machine head, and thereby make the structure simplified by letting a needle bar cam, a cloth hold cam and a drive lever in each sewing machine head be so set that a mutual interlocking relation is discontinued when an evacuation mechanism is so operated that a needle bar and a cloth holder are thereby evacuated. CONSTITUTION: When a needle bar 22, a nipple 27 and a cloth holder are evacuated by an evacuation mechanism 90, a needle drive lever 70 and the roller 72 of a nipple drive lever come out of respective cam grooves through a needle bar cam 14, and the cut-out section 14a of a nipple cam. The roller of a cloth holder drive lever comes out of the outer circumference of a cloth hold cam. Therefore, an interlocking relation between a sewing machine main spindle 12 and each drive lever 70, is thereby discontinued at the time of the evacuation. Accordingly, at the time of the evacuation, if evacuation operations are performed at a given sewing machine head in the multi-head type sewing machine, even if the main spindle 12 is restarted, the needle bar 22, the nipple 27 and the cloth holder of this sewing machine head will never be driven up and down, thereby they are entirely suspended.
