CONSTITUTION:A roller 4 is contacted with a steel plate 1 supported by rollers 2, 3 and arbitrary external force is set by an external force adjusting handle 12 to scan the steel plate 1 in the width direction thereof by a scanning mechanism 9 while external force is applied thereto through the roller 4 by a spring 6. In this case, the repulsive force due to the stress distribution of the steel plate 1 is grasped as the displacement of a support 5 and said displacement is detected as an electric signal by a differential transformer 7 while the electric signal is converted to predetermined voltage output by a displacement converter. At the same time, a position detecting signal is outputted corresponding to the scanning position of a stress distribution measuring apparatus by a position detector 11. These signals are converted to digital signals in an input interface part and operation is performed in an operation apparatus by using the output of the input interface part while refering to the calibration value stored in a calibration value memory apparatus.

Abstract: PURPOSE: To withdraw one veneer sheet at a time by means of a pressure reduction adjustable suction head so provided as to be free to move vertically with a contact device so arranged on the circumference thereof as to be free to slide.  
     CONSTITUTION: While a suction head 2 arranged above veneers 1 stacked in a container 6 is moved downward, a contact device 3 slides down until the lower ends of both profected portions 5 thereof aligns the lower end of a suction section 4. Subsequently, the section 4 is pressed against the veneer 1 with the portions 5. Then, the stack of the veneers 1 is compressed until the height A thereof is reduced by C to B. With the actuation of a vacuum pump, the top sheet of the veneers 1 is sucked by the section 4 at a reduced pressure P1. While the veneer sheet  1 is brought up the device 3 is slightly slid up. Then, the pressure of the head 2 thus reduced is raised to P2. The device 3 is slid down to shifrt the members 5 to a level lower than the section 4, whereby the veneer 1 is bent. Consequently, one veneer sheet is withdrawn at a time.

Title: Aligner
Inventor: OYAMA YASUO
IPC: H01L21/027
Filed: 1990-02-09
Abstract: PURPOSE:To conduct the optimum exposure for a photoresist film by installing an equipment to detect a reflected light from the photoresist film. CONSTITUTION:When a photoresist film 9 formed on a semiconductor substrate 4 is exposed with light 3 from a light source 1, a detector 5 to measure the reflected light 3A and an indicator 6 are installed. The semiconductor substrate 4 to be exposed is coated with a positive-type resist film. When an exposure is conducted with gamma rays, the reflecting strength of the reflected light is taken by the detector 5 as the reflected light 3A from the semiconductor substrate since the light stops contributing to a photochemical reaction of the photoresist and comes through the photoresist film as the gamma rays is irradiated longer and longer. When an equipment is installed in this exposure system to make the exposure constant, a condition of a photochemical reaction of the photoresist itself can be known by the peak of the rising voltage indicated when an exposure is conducted under the same conditions. With the result obtained, adjustments is made to the exposure manually. By this method, the optimum exposure can be conducted, raising an yield of a workpiece such as the semiconductor substrate.
