Title: Semiconductor device
Inventor: TANIDA YUUJI
IPC: H01L21/8247
Filed: 1981-11-27
Abstract: PURPOSE:To increase the degree of integration without reducing memory holding time by making the thickness of an Si3N4 film among insulating films forming an MNOS type nonvolatile memory 35nm or thinner and the thickness of an SiO2 film 1.5nm or thicker. CONSTITUTION:The SiO2 film 3 and the Si3N4 film 4 are shaped between a polysilicon gate 5 and a substrate 1. Programme voltage Vp must be multiplied by 1/k in order to multiply the degree of integration of the memory by k<2>. The insulating films must be multiplied by 1/k for that, but the SiO2 film 3 cannot be brought to 1.5nm or thinner because memory holding time is shortened when the SiO2 film 3 is 1.5nm or thinner. Accordingly, the conditions of integration can be satisfied when the thickness of the SiO2 film 3 is made 1.5nm or thicker and the thickness of the Si3N4 film 4, 35nm or thinner.

Title: Solid electron beam generator
Inventor: MIYAWAKI MAMORU
IPC: H01J1/30
Filed: 1986-08-12
Abstract: PURPOSE:To increase quantity of electrons emitted by injecting electrons from a 1st range to a 2nd range and emitting the electrons from an electron emission surface in the 2nd range. CONSTITUTION:In forming a heterojunction of a 1st layer 2 including a 1st band gap, and a 2nd layer 5 including a 2nd band gap which is narrower than the 1st band gap, an inclined layer 4 in which ratio of mixed crystals of a certain material is gradually changed is inserted between the 1st layer and the 2nd layer, and electrons are injected from the 1st layer to the 2nd layer, while the electrons are emitted from an electron emission surface in the 2nd layer. Due to insertion of the inclined layer 4 between the layer 2 and the layer 5, ratio x of mixed crystals of A1 is gradually decreased, and the ratio reaches 0 at the boundary with the layer 5. Because of insertion of the inclined layer 4, spikes or the like are not produced in the hetero-boundary between the layer 2 and the layer 5, and no obstacles such as spikes are produced, thereby many more carriers can be injected to the layer 5 and carrier injection efficiency improved. Thus quantity of electrons emitted can be extremely increased.

Title: Special position extracting device for image
Inventor: IIJIMA KATSUMI
IPC: G06T5/20
Filed: 1987-07-29
Abstract: PURPOSE:To promptly and accurately extract or identify the image of an arbitrary position from the images with a simple device constitution by optically repeating a filtering processing plural times through the use of a template, and extracting the arbitrary position from the image. CONSTITUTION:When the special position of the image is extracted, first, the template of a desired image position to be extracted is prepared. The filtering processing is executed with the aid of a weight coefficient. That is, when the position, which has high correlation with the template, exists in an objective image as the result of the filtering processing, the part brighter than other part (a luminescent point part) appears in the output image. Further, to fix the extracted position, the image-formation scale factor of a spatial sump optical system is changed, and the template preparation and the shift of the image in (x) and (y) directions are repeated. In such a time, the template suitable for the image-formation scale factor in accordance with the change of the image-formation scale factor is used. By shifting an image sensor 4 in the (x) and (y) directions, changing the light quantity of the image projected on the image sensor 4 with an illuminating means, and multiply exposuring the image, a filtering processed image is formed on the image sensor 4.
