Title: X-ray inspecting device
Inventor: HAYAKAWA YASUO
IPC: G01N23/18
Filed: 1988-02-03
Abstract: PURPOSE:To easily judge whether or not there is an internal defect in a body by multiplying a detected value of each data sampling position of an X-ray quantity detecting means by a corresponding attenuation constant. CONSTITUTION:Data at each sampling position of an X-ray image which is transmitted through a material 3 to be inspected is converted by an A/D converter 7a into a digital value, which is stored in a memory 7b temporarily and outputted to a multiplier 11b. Then the command signal from the control part of an image processor is outputted to a 1/alpha setter 11a to assign the address corresponding to the sampling position of the data outputted from the memory 7b. Consequently, the 1/alpha setter 11a outputs the data (1/alpha) stored in the address. The multiplier 11b multiplies the output data of the memory 7b by the output data of the 1/alpha setter 11a and outputs the value to a memory 11c. Consequently, even when the material to be inspected has ununiform thickness in an X-ray irradiation direction, the brightness of a visible image is uniformed and light and shade due to the defect are easily discriminated.

Title: Photographic light shielding paper for daylight room
Inventor: NAKAMURA AKIRA
IPC: G03F1/90
Filed: 1980-02-23
Abstract: PURPOSE:To enhance the light shielding property of light shielding paper by using yellow mat art paper. CONSTITUTION:Coating layer 2 mixed with red pigment is formed on one side of yellow mat art paper 1, and coating layer 3 mixed with yellow pigment on the other side. Red square pattern 4 is then printed on layer 3. Conventional light shielding paper using white coated paper [refer to Publication No. (examined) 52-2321 in the Japanese ''Published Examined Patent Application''] shields light unevenly owing to ununiform paper making and can not be used in a daylight room. Yellow mat art paper shields light evenly. By printing red square pattern 4, pattern 4 disappears when a photograph stuck to this light shielding paper is seen on a red light table, so work is facilitated.

Abstract: PURPOSE:To reduce point defect density in a semiconductor epitaxial layer by ion-implanting an impurity to the layer, and then heat-treating the layer in a state that a potential gradient is formed in the thicknesswise direction of the layer. CONSTITUTION:Two ZnSe epitaxial layers 2 implanted with an impurity are superposed in close contact with the surfaces of the layers 2 on a GaAs substrate 1. A voltage E is applied between electrodes 3 formed on the substrate 1. A potential gradient, i.e., an electric field is presented in the thicknesswise direction of the layer 2. After it is heat-treated in a state that a voltage E is applied between the electrodes 3 of the substrate 1 for a predetermined period of time, the substrate 1 is cooled to room temperature in a state that the voltage E is being applied. The implanted impurity is activated at the time of heat treating, carrier is moved from the layer 2, and the carrier density in the layer 2 is reduced at the time of heat treating. Thus, the point defect density in the layer 2 is reduced.
