Title: Preparation of semiconductor infrared-ray detecting element
Inventor: FUKUDA TAKAYASU
IPC: H01L31/103
Filed: 1979-09-28
Abstract: PURPOSE:To obtain a high response speed infrared-ray detecting element by a construction wherein the capacity and sheet resistivity of an Hg1-XCdXTe P-N junction are lowered so that most of the photons are absorbed in a P type crystal layer. CONSTITUTION:An N type Hg1-XCdXTe 1 is heated to extract Hg and to make a P type substrate 2. Then ZnS 3 is deposited on the substrate and an opening is made in the layer 3 to diffuse Hg. An N layer 4 is formed by filling up the empty grid of the substrate 2 to selectively form a P-N junction 5. In addition, an N<+> layer 6 is formed by injecting B ions in order to obtain a double layer. With such a construction as this, the sheet resistivity of the P type substrate is lowered because of the N<+> layer 6, while the junction capacity is made smaller because a depletion layer is provided in the P-N junction. If the double layer consisting the layers 4-6 is allowed to have a thickness of about 3mum, infrared-ray photons to be injected can be fallen on the P layer which is almost nearly fast as carrier transferring, so that a high response speed infrared-ray detecting element can be obtained.

Abstract: PURPOSE:To compensate the degrading of waveform equalizing ability to chroma cmponents, by providing a color component emphasis filter for the input side of a transversal filter. CONSTITUTION:The 1st and 2nd filters 41 and 42 are connected to the input and output of a transversal filter 2.

Abstract: PROBLEM TO BE SOLVED: To make steam easy to pass through at the time of cooking, and at the same time, prevent a stickyness due to an excessive oil from generating, and reproduce a high quality by a method wherein a groove is formed at a location which is lower than the bottom upper surface of a recessed where a cooked food is housed, and the tip end of the groove is extended to the outside of the recess. SOLUTION: Housing chambers 3 having a peripheral edge around the opening 1 are formed, and in each housing chamber 3, recesses 4 where foods are housed under a defined state, are provided in parallel. In this case, a radial groove 5 is formed at a location which is lower than the bottom upper surface 4a of the recess 4, and the tip end is extended to the outside of the recess 4. By using this tray, when a cooked food A is housed, a space 6 is formed between the bottom surface (a) and the recess 4, and steam which rises at the time of cooking is released, and the surface is prevented from swelling. At the same time, by dropping and accumulating an excessive oil from the cooked food A, in the groove 5, a stickyness is prevented from occurring. By this method, a quality which is close to that at the time of a deep frying, can be reproduced.
