Title: Nonvolatile semiconductor storage device and its manufacture
Inventor: HIRANO KANJI
IPC: H01L21/8247
Filed: 1990-05-02
Abstract: PURPOSE:To reduce the gate length on a plane and facilitate miniaturization, by making all the gate insulating film exist in a trench part on the boundary region of a selective oxide film on the periphery, and preventing the gate insulating film from climbing onto the peripheral selective oxide film. CONSTITUTION:The gate part of an MNOS transistor 2 is formed in a trench 6 arranged on the surface of a substrate 1, and the gate part 11 of an MOS transistor 3, which does not contain a silicon nitride film 8 in the gate insulating film, is formed on the substrate 1 adjacent to the gate part. The gate part 11 of an MOS transistor 33 forming the peripheral circuit part is formed at the same time as the gate part 9 of the MOS transistor 2 formed to be adjacent to the gate part of the MNOS transistor 33. Finally a structure is constituted in the manner in which, in the boundary region where the gate part of the MNOS transistor 2 comes into contact with a selective oxide film 4 on the periphery, the gate insulating film 11 of the MNOS transistor 2 does not climb onto the selective oxide film 4 on the periphery. Thus the gate length bridges the bottom surface and both side surfaces of the trench part, the channel length is kept when the size on the plane is reduced, and miniaturization is advanced.

Title: Scintillation camera
Inventor: TANAKA MASATOSHI
IPC: G01T1/164
Filed: 1984-06-08
Abstract: PURPOSE:To improve the accuracy of position detection of a scintillation camera by providing a dividing circuit between a matrix adding circuit and a position calculating circuit, and dividing a matrix signal by an energy signal. CONSTITUTION:An incident gamma ray is converted to light by a scintillator 1, and converted to an electric signal 101 by a photoelectric multiplier 2. The electric signal is added by a matrix adding circuit 3 for each matrix and becomes a matrix signal 102, and all of them are added by an adding circuit 8 and become an energy signal 106. Dividing circuits 20 of X9 channel and Y5 channel output a matrix signal 102'' obtained by dividing the matrix signal 102 by the energy signal 106. As the matrix signal 102'' is divided by the energy signal 106 by the dividing circuit 20, the magnitude as a whole becomes constant regardless of energy of incident gamma rays, statistical fluctuation in the scintillator 1 and photoelectric multiplier, and spread in magnitude of signals caused by unstable factors of the circuit.

Abstract: PURPOSE:To enable thinning of an image, by reading out an image from the surface of a document then holding the read-out image data and forming an electrostatic latent image onto a photo-sensitive body based on processed image data and according to an instruction. CONSTITUTION:An electrostatic latent image is formed on a drum by a beam reflected from the surface of a document being irradiated through a lamp 1. When a CCD 16 in a reader performs read-out operation of the document, only the sections of 'P' and 'I' are recognized as sections having low reflection coefficient. When the image data are subjected to serial/parallel conversion and stored, the non-recognized white section '0' is processed to recognized section '1' and recognized data at a point '1' transiting from '1' to '0' are processed by predetermined amount. A laser unit 17 turns a laser ON for '0' in the data while turns the laser OFF for '1'. Longitudinal image sections of electrostatic latent images 'P', 'I' are thinned then the images are developed through a developer 10 and outputted.
