Title: Granular substance manufactured by refining converter slag and manufacture thereof
Inventor: TAGUCHI KIYOMI
IPC: C04B18/14
Filed: 1978-04-17
Abstract: PURPOSE: To manufacture a granular substance which hardly undergoes slaking disintegration and has various uses such as civil engineering and construction by spouting a high-speed air jet upon molten converter slag in the vicinity of a slag outflow part so that the diameter of the resulting granular substance and the oxidation rate of the slag are regulated to below and above a specific value, respectively.  
     CONSTITUTION: Molten converter slag 3 is dropped from ladle 2 optionally through channel 2, and high-speed air jet 5 is sprayed upon the dropping slag from air nozzle 4. Thus, the molten slag is spheroidized by surface tension, solidified by cooling from the surface, and turned to a granular substance at dropping point 5. At this time, air jet 5 is so spouted that the diameter of the granular substance is regulated to below about 2 mm and the oxidation rate of the slag above 70%. In order to regulate the diameter, etc., the ratio of air flow rate and slag wt. is set to 400W6200 Nm 3 /T and the speed of flowing air to 80W300 m/s. Thus, esp. slakable CaO in Ca solid soln. in the slag is fixed as dicalcium ferrite (2CaO.Fe 2 O 3 ) with Fe 2 O 3  formed to be protected from slaking.

Filed: 1981-03-30
Abstract: A texturising nozzle for synthetic filaments is openable and closable to facilitate lacing up. The nozzle comprises a two-part carrier structure with the parts (10, 12) movable towards and away from each other to open and close the nozzle. The thread path through the nozzle is defined by means of insert elements (18, 20) releasably mounted on the carrier structure at least in that region of the path in which the main texturising step is performed.

Title: Logic circuit
Inventor: MURASAWA KEIJI
IPC: H03K19/088
Filed: 1980-04-10
Abstract: PURPOSE:To prevent a breaking time from varying with the period of an input by quickening responses of a rise time and fall time by compressing logical amplitude, by determining the voltage level of the high value of an output signal by shifting the low-value voltage level of an input signal. CONSTITUTION:The high-value voltage level of an output signal rises from the low-value voltage level of an input signal up to a constant voltage level shifting in level by the anode-cathode forward voltage of diode D18 through D18, and the high-value voltage level drops by one-fifth that of the conventional TTL circuit. Therefore, capacitive charge parasitic to output terminal 16 decreases and the charge and discharge time of this capacity is shortened, so that the rise and fall times are shortened. Further, the current charging the parasitic capacity is the sum of the current flowing through resistance 17 and resistance 14 of a load circuit and that flowing through D18, so that the rise starting time is advanced. Furthermore, variation in fall time due to the period of the input signal can be prevented because it takes much time to stabilize the output signal from the low-value to high-value voltage level.
