Title: Toggle type mold clamping device
Inventor: SAKAI MASAYA
IPC: B29C33/22
Filed: 1986-03-31
Abstract: PURPOSE:To uniformly apply necessary mold clamping forces over the whole mold by a method wherein a pressure regulating valve is controlled by an output signal sent from a setter by comparing a detection value sent from a detector to detect the inner pressure of a regulating cylinder and a set value sent from the setter setting the mold clamping forces with each other by a comparator. CONSTITUTION:A pressure detector 11 provided din an oil hydraulic circuit 9 is connected to a comparator 12 so as to detect the pressure in a regulating cylinder 8 in order to input the detected pressure to the comparator 12. When necessary old clamping forces in the respective stages during mold closing and mold opening processes are set at a setter 14, under the state that the position of a movable platen is detected with an LS, an encoder or the like, a pressure regulating valve 13 is controlled by output signals sent from the setters 14 in the respective sections so as to be able to give all the regulating cylinders 8 uniform necessary inner pressure. Accordingly, because the respective tie bars 3 are extended and contracted by the regulating cylinders 8 so as to make the tensile force (mold clamping force) or the tie bar 3 constant, the constant mold clamping force can be obtained under absorption of the minute change of the mold clamping force due to thermal influence and the like.

Title: Injected black liquid particle size control system in heavy oil mixed firing recovery boiler
Inventor: IIZUKA KAZUYUKI
IPC: F23G7/04
Filed: 1987-03-28
Abstract: PURPOSE:To maintain proper injected black liquid particle size to always ensure an optimum firing condition by detecting the flow rate of supplied heavy oil or combustion air so as to modulate the temperature of the injected black liquid. CONSTITUTION:The black liquid temperature regulator 37 is manually set in accordance with black liquid temperature, properties, etc. As the flow rate of heavy oil 5 injected from a heavy oil burner 4 into the furnace 1 changes, the compensation value by a black liquid temperature compensator 35 is caused to be changed with the heavy oil flow rate. With an increase in heavy oil flow rate, the compensation value is reduced, the compensated setting value from an adder 36 becomes smaller, a black liquid temperature regulator 32 outputs an operation signal to close a steam flow rate regulator valve 31, the heating intensity by a heater 27 is reduced, and so, the black liquid temperature is reduced. Due to the temperature reduction, the dryness of black liquid particles sprayed from a black liquid burner 2 is lowered, and the dry condition in the furnace maintains an optimum condition for firing. As a result, proper injected black liquid particle size can be maintained to always ensure the optimum firing condition.

Abstract: PURPOSE:To enhance the close adhesiveness of a paint, by removing the uppermost surface layer of various kinds of alloy layers on the surface of a molten zinc plated steel plate to carry out painting. CONSTITUTION:The alloy layer on the surface of a molten zinc plated steel plate usually consists of a delta phase of FeZn7, a zeta phase 3 of FeZn13 and a eta phase 4 comprising Zn forming a solid solution along with a slight amount of Fe as an uppermost surface layer formed on the steel plate 1. After the eta phase 4 is removed to expose the zeta phase or the delta phase, painting is carried out to make it possible to enhance close adhesiveness with a paint. In this case, the removal of the eta phase is pref. carried out by electrolysis from the point of view of efficiency and, for example, the eta phase is removed by a method wherein the plated steel plate is electrolyzed in an electrolyte such as a NaCl+ ZnSO4 solution by using a cathode comprising lead or platinum at voltage of about 300-500mV and current density of about 10-30mA/cm<2>. An electrolytic time is relied on current density and the thickness of the eta phase but usually 1-3min at current density of about 20mA/cm<2>. In order to further enhance the close adhesiveness of a paint, pretreatment such as chemical forming treatment may be carried out.
