Title: Variable speed extruding method
Inventor: YAMANA JUNICHI
IPC: B29C48/92
Filed: 1990-03-27
Abstract: PURPOSE:To change extrusion speed in response to conditions at operation by a method wherein the speed of an extruder and the speed of a draw conveyor, which carries the rubber material extruded from the extruder, are memorized for every rubber material so as to select the speeds of the extruder and of the draw conveyor for the corresponding rubber material from memorized information. CONSTITUTION:The speed of an extruder 1 and the speed of a draw conveyor 3, which carries the rubber material extruded from the extruder 1, are memorized for every rubber material by means of normal speed memories 5 and 8. Next, from said memorized information, the speeds of the extruder 1 and of the draw conveyor 3 for the corresponding rubber material are selected and the respective selected speeds are controlled under mutual relation on the basis of outside information. For example, at the early stage of extrusion, in which the setting times of utilities are secured, or when there are sufficient quantities in stock in a stock yard 4, the extrusion speed is decelerated, while when there are not sufficient quantities in stock in the stock yard 4, the extrusion speed is accelerated.

Title: Method and device for flaw detection
Inventor: ISHIHARA MICHIAKI
IPC: G01N27/83
Filed: 1989-03-27
Abstract: PURPOSE:To quantitatively detect defects with a high precision by giving an AC bias magnetic field, whose amplitude is larger than the coercive force of a magneto-optical effect element. CONSTITUTION:When linearly polarized light PL is thrown to a magneto-optical effect element 1a, it is reflected on a reflection film 1c and passes an analyzer 4 and is made incident on a photodetector 5. Power is supplied to an AC bias exciting coil 1b to give an AC bias magnetic field Hp whose amplitude is larger than the coercive force of the element 1a. When the current of the same phase as the current supplied to the coil 1b is supplied to an excitation coil 3 to give the AC magnetic field to a material M to be subjected to flaw detection, a leaked magnetic flux is generated in relation to a defect Ma and acts upon a detecting head 1, and the AC magnetic field obtained by amplitude modulation of the magnetic field Hp is given to the element 1a. Consequently, a square wave corresponding to the polarity change of the angle of rotation of the plane of polarization is changed, and the leaked magnetic flux is proportional to the defect Ma and therefore, the phase or the time width of the square wave is detected to quantitatively detect the defect Ma with a high precision.

When the temperature 30 exceeds the set temperatue, the three way valve 26 is switched over onto the bypass side 27. Thereby hot water circulates through the forward and backward channels 20 and 21 and the bypass channel 27. Then the hot water can be taken out in a short time by opening the faucet 23, while the three way valve 26 is switched over onto the water supply port 24 side of a hot water supply unit 16 to make the hot water flow through the forward channel 20 irrespective of the detected temperature 30 by a water circulation signal of a flow rate detector 29. This construction enables the elimination of a cooling effect caused by a heat exchanger and also the reduction of the loss of heat radiation.

Filed: 1985-04-12
Abstract: PURPOSE:To perform automatic focusing operation by allowing two detectors to pick up an image of a specific contrast point of a projected strip pattern at the same time through an optical system and determining the position where contrast is equal as a focusing position. CONSTITUTION:The projected strip pattern is picked up through a half-mirror 16 by using linear image sensors 17a and 17b and then the outputs of the sensors 17a and 17b coincide with each other when a wafer is at the focusing position, i.e. image-formed on the middle point on optical axes of the sensors 17a and 17b. For the purpose, a subtracter 19 calculates the difference between the outputs of the sensors 17a and 17b through amplifiers 18a and 18b and controls the driver 22 of a Z-axial moving mechanism 23 for the wafer so that the difference is eliminated. Consequently, focusing is attained and a linear image sensor 5 for circuit pattern detection detects a sharp image at any time. Consequently, the wafer consisting of many kinds of materials which differ in refractive index, etc., is put in focus automatically.
