Abstract: PURPOSE:To provide structure consisting principally of ferrite and graphite and to improve ductility and workability by decreasing the content of P, S and Mn in a carbon steel and subjecting the carbon steel to annealing under specific conditions after hot working and cold working. CONSTITUTION:A steel having the compsn. contg. 0.15-0.95% C, <0.20% Mn, 0.02-0.30% sol Al, <0.006% N, <1.0% Si, <0.010% P and <0.010% S and satisfying the conditions P%XS%<=10X10<-6> is produced. The billet thereof is hot-rolled and is descaled by pickling.

Title: Ignition device for multi-cylinder engine
Inventor: HARADA HITOSHI
IPC: F02P7/03
Filed: 1980-11-13
Abstract: PURPOSE:To obtain strictness in ignition timing of an ignition device for distributing low voltage by supplying successively current to ignition coils in response to those signals inputted to an ignition timing signal generator and a standard signal generator. CONSTITUTION:The signals generated in an ignition timing signal generator 1 according to a lead angle corresponding to RPM of the engine become clock pulses applied to a control counter member 9 through a generator 7. While, when the engine has six sylinders, one signal is generated in a standard signal oscillator or generator 2 every generation of the sixth ignition timing signals. Thus generated signals are inputted as clear signals to the control counter member 9 through a wave form transformation circuit 11 and single-stable multi- vibrator 12 to establish the initial setting for the terminal to be powered. A standard signal generation stopping circuit 15 is arranged to be inoperate before a standard signal is inputted in the counter member 9, and to stop its speration when any standard signal is not inputted during rotation, so that any mis-operation may be prevented.

Abstract: PURPOSE:To improve the workability by forming a lead which has been partially covered with an insulator in a groove provided on a non-conductive magnetic substrate so that the upper magnetic block can be joined on a coil layer without getting on the lead at the time of attaching the upper magnetic block. CONSTITUTION:A lead 9 which has been partially covered with an insulator 10 is formed in a groove 8 provided on one face of the lower magnetic block 7 made of a non-conductive magnetic material, and film thickness of the lead 9 is shallower than depth of the groove 8.

Title: Cylindrical screen photosensitive member
Inventor: MURAI KEIICHI
IPC: G03G15/05
Filed: 1977-12-28
Abstract: PURPOSE:To maintain the roundness by providing a frictional freedom between a cylindrical supporting member and screen photoreceptor so as to eliminate effects to screen photoreceptor even if the cylndrical supporting member twist or distorts. CONSTITUTION:A spacer 9 made from material excelling in slipping property such as polyester is wound around a cylindrical supporting member 6. A screen photoreceptor 1, maintaining its roundness, is wound around the cylindrical supporting member 6 in a manner to cover the spacer 9, not applying immoderate external force. The both ends of the same are adhered and secured to the spacer 9 by means of an adhesive tape 19 on a linkage supporing part 8. Thus, the other parts of the photoreceptor 1 are freed from the cylindrical supporting member 6. Therefore, even if the supporting member twists or distorts due to undesired force while in use, such actions are absorbed by said degree of freedom, so that no effects are applied to the photoreceptor 1. At the same time, the roundness may be maintained.

Title: Electro-magnetic fuel injection valve
Inventor: SAKAI TATSUO
IPC: F02M51/06
Filed: 1981-10-09
Abstract: PURPOSE:To stabilize the fuel injection performance by preventing the inclination of a valve body and a movable core in an electro-magnetic fuel injection valve automatically and preventing the shoulder section of the movable core from contacting against a fixed core thus seating correctly. CONSTITUTION:When a valve body 16 will seat while inclining at the nonconducting time of an electromagnetic coil 12, the central point A of the pressing of a spring 26 is lower than the center of curvature (c) to produce the moment around the center C by the pressing force Fs to be applied on the point A thus to rotate a valve body 16 in the arrow direction and to correct the inclination of the valve body 16. When the power is supplied to the coil 12 to adsorb the movable core 15 to the fixed cores 13, 14 and contact against it while inclining, the pressing force FS of the spring to be applied on the functioning point A of the spring 26 will provide the moment around the center of gravity G thus to rotate the valve body 16 in the arrow direction. Consequently the inclination of the movable core 15 is corrected thereby the shoulder section 15 is prevented from contacting against the fixed cores 14, 15.
