Title: Method for continuously casting surface clean steel
Inventor: NAKANO TAKESHI
IPC: B22D11/112
Filed: 1993-03-05
Abstract: PURPOSE:To prevent the generation of surface fault at the time of rolling by reducing the oscillation mark depth in a continuously cast slab. CONSTITUTION:This continuous casting method for surface clean steel is featured by using an immersion nozzle which is formed in an integrated shape so as not to enter the air and has plural molten steel discharging holes set horizontally or downward and in which a ratio S/(s) is <=0.55 wherein S is the sum of the cross sectional areas of the discharging holes and (s) is the cross sectional area of the inner hole, regulating the oscillation cycle to 200-300cpm and limiting the stroke to <=+ or -3mm. Therefore, the fluctuation of the level of the molten steel surface in a mold can be controlled to <=2mm, by which the oscillation mark depth is made to be <=300mum. Then, even in the case of rolling the cast slab without repairing its surface, the cast steel free from surface flaw due to the oscillation mark can be produced.

IPC: C08J7/02
Filed: 1979-06-04
Abstract: PURPOSE: The surface of moldings containing an olefin resin, rubber, and styrene resin is treated with a solution of chlorinated polyolefin, whereby polyolefin moldings being readily coated and withstanding the temperature of 100°C are obtained.

Title: Contactless ignition device for permanent-magnet generator type internal-combustion engine
Inventor: TERADA KANECHIYO
IPC: F02P5/15
Filed: 1985-04-02
Abstract: PURPOSE:To prevent over-advance during increasing and decreasing in a supply voltage in a power circuit and carry out ignition in a low-speed fixed position, by providing a rotational speed detecting circuit for controlling an input or an output of an advance operating circuit when an engine rotational speed is less than a set value and setting an ignition timing at the low-speed fixed position. CONSTITUTION:Even when a charging voltage of an operating capacitor 108 is reduced during increasing and decreasing in a supply voltage in a power circuit upon starting or the like, a set rotational speed in a rotational speed detecting circuit 950 is controlled to become high. Therefore, the detecting circuit 950 decides that the engine rotational speed is less than the set rotational speed, and control an input or an output of an advance operating circuit 30 to hinder generation of an advance signal and set an ignition timing at a low- speed fixed position. Thus, even when the supply voltage in the power circuit is being increased and decreased, over-advance may be prevented to reliably carry out ignition at the low-speed fixed position.
