Title: Method for feeding molten steel containing zr
Inventor: KANO TAKASHI
IPC: B22D11/10
Filed: 1994-05-09
Abstract: PURPOSE:To prevent the nozzle clogging with the steel containing Zr by employing the ZrO2 refractory at least to a part of the nozzle such as the sliding nozzle. CONSTITUTION:In feeding the molten steel 12 containing Zr to a mold 18 for the continuous casting through nozzles such as a sliding nozzle 13, a lower nozzle 15 of the sliding nozzle, and a dipping nozzle 17, ZrO2 is employed as the material of at least a part of these nozzles, and the content of ZrO2 is >=10wt.%. Even when Zr in the molten steel containing Zr is oxidated to be ZrO2, and this suspended inclusions are flocculated in the vicinity of the refractory of the nozzles to form the flow layer of high viscosity, a smooth layer of low melting point is formed on the inner wall surface of the nozzles to make it difficult for the ZrO2 inclusions to be adhered to the inner wall surface of the nozzles. This constitution avoids the nozzle clogging by the adhesion of the ZrO2 content.

Title: Refresh control system
Inventor: FUJII SHIGERU
IPC: G11C11/406
Filed: 1979-07-26
Abstract: PURPOSE:To reduce the access waiting time of dynamic type memory unit refreshed in a given period, by performing refresh when the memory access request and memory-busy are absent. CONSTITUTION:The refresh trial control section 41 is added to the refresh control section 1' to generate the refresh start signal l5' when the memory busy signal l7 and the access request signal l8 are both absent and to produce the memory access inhibit signal l4' at the same time.

Abstract: PURPOSE:To widen the output range of an image pickup element with the change of light quantity of a light source by providing an attentuation means to the first state of an analog signal processing system, controlling the light quantity of the light source in accordance with the types of originals and controlling variably the attenuation factor of the attenuation means in accordance with the output range of the image pickup element. CONSTITUTION:An attenuator 1 attached to the first stage of an analog circuit 3025 is turned off by the control signal received from a controller 3039 when a transmissive original 3007 uses a negative film. Then the attenuator 1 is turned on when the original 3007 uses a positive film. Thus the light quantity of a light source 3001 which radiates the illumination light transmitting through the original 3007 is set double as much as the reference value so that a double output range is secured for the output signal of a CCD line sensor 3022 when the original 3007 uses a positive film. When the attenuator 1 is turned on and the signal level is set at 1/2 multiple angle, the light quantity is set at the reference level for the light source 3001 which emits the illumination light transmitting through the original 3007 of a negative film.

Abstract: PURPOSE:To simplify the construction of a valve stopping device by inserting relatively rotatably a cam shaft in a cam and sliding the cam axially on the cam shaft to make tapered fit surfaces contact or separate from each other for changing over the swing and stop of a rocker arm. CONSTITUTION:When pressurized oil is dropped from a hydraulic chamber 5 to a drain, a cam 3 is deviated to the journal section 4 side by the action of a spring 7, and an engaging hole 3b formed in an eccentric position to the rotary center of cam 3 on one end of the cam 3 and having a tapered surface is spaced from an engaging section 1a having a tapered surface formed in same eccentric position.
