IPC: C23C2/00
Filed: 1992-04-16
Abstract: PURPOSE:To prevent the impairment of washing efficiency and quality by providing a sludge conveyor for discharging bottom dross in the bottom of the treatment chamber. CONSTITUTION:Molten zinc is put into a zinc pot 1 of the continuous treatment chamber for metallic sheet surfaces. The steel sheet 3 is immersed into the zinc pot 3 by using a roller 3. The sludge conveyor 5 for discharging the bottom dross deposited on the bottom of the zinc pot 1 of the treatment chamber is provided. A funnel-shaped baffle plate 4 is disposed within the pot 1 to introduce the dross generated on the periphery of the steel sheet 2 of the conveyor 5 and to partition the dross discharged by the conveyor 5 from the steel sheet.

Title: Coke extrusion control system
Inventor: TOKUDA ATSUHIRO
IPC: C10B41/04
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To provide a coke extrusion control system having a function to perform a control based on the reaction force against a pusher. SOLUTION: This system works as follows: a control section 40 reads the rotating speed of an electric motor 141 detected by a pulse generator 42 and the actual notch position of a secondary resistor 44; in the control section 40, the reaction force against a pusher 12 from coke is estimated by an observer based on the rotating speed and notch position; based on the reaction force thus estimated, an acceptable generated torque when one-notch is raised is calculated; when an actual generated torque in the same situation is less than the acceptable generated torque thus calculated, a notch raising operation for the secondary resistor 44 is performed; thereby affording the pusher with an extrusion force overcoming the reaction force along with preventing excessive current from flowing in a notch changeover operation.

Title: Dial pulse make rate measuring instrument
Inventor: MORIYA TORU
IPC: H04Q1/32
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To reduce the make rate measurement error of a dial pulse even though the impedance of a circuit side changes and to improve measurement accuracy by converting a dial pulse signal into a digital value, monitoring the digital value to perform decision of make or break and measuring a make rate from the results. SOLUTION: When a telephone set transmits a dial pulse being a dial signal A, current is caused to flow into a circuit is changed. The circuit 10 of a testing machine converts the current into a voltage and eliminates chattering and noise through a filter to make it a dial signal B. An analog-to-digital conversion circuit 11 converts the signal B into a digital signal in a prescribed cycle. A processor 12 decides that the digital signal as break in the case the rate of change within fixed time is equal to or more than a fixed value and decides it as make when the rate of change is below the fixed value. The processor 12 reproduces a dial signal D based on these decisions and calculates a make rate based on the reproduced dial signal D.

Title: Method for quality judgment of welded product by frictional welding and its apparatus
Inventor: MAEHARA KAZUO
IPC: B23K20/12
Filed: 1980-07-16
Abstract: PURPOSE: To judge the quality of welded portions during the course of welding process without any inspection process, by measuring the frictional force on the welding face at the time of frictional movement in the process of frictional welding.  
     CONSTITUTION: The frictional force at the time of frictional movement has a close relationship with the weldability. Because of this, for example, a fixed supporting device 26 is attached to a pressure jig 25 of a frictional welding machine so that it may rotate freely, and a projection 26' of a detecting device working body is installed on the device 26. A load cell 22 is attached to a sensor receiving table 27 fixedly installed on the base of welding machine, and a compressive stress shown by the arrow 29 is applied by the frictional force shown by another arrow 28. Therefore, when the distortion signal of the cell 22 is fetched, the frictional force can be measured. When this value is smaller than a previously set value, the welded product is considered as excellent, and when it is larger than the previously set value, the product is considered as inferior.
