Abstract: PURPOSE:To obtain a dynamic RAM whose area per cell is reduced and integration density is increased by separating in the longitudinal direction a diffusion layer of opposite conduction type formed on a substrate surface and a diffusion layer of capacitance part to increase the withstand voltage of this part. CONSTITUTION:A first groove 4 is formed on a P-type single crystal silicon substrate 1 by photoetching. That is, the desired regions of Si3N4 film 3, SiO2 film 2 and silicon substrate 1 are subjected to etching in order, and the groove is formed. A SiO2 film 5 is formed on the whole surface of a wafer and reaction ion etching is applied thereon. The first groove 4 is subjected to the deeper etching to form a second groove 44. Boron is doped on the inner wall of the groove 44, and a P<+> diffusion layer 6 is formed, then a capacitance insulating film 8 is formed. After the vapor growth of polycrystalline silicon 9 is applied on the whole surface of a wafer, the polycrystalline on the surface of the Si3N4 film 3 is eliminated and the polycrystalline silicon 9 is buried in the groove 44. After a contact hole 7 is formed by photoetching, an N<+> diffusion layer 10 is formed on the substrate surface of the contact hole part. At this time, the N<+> diffusion layer 10 and the P<+> diffusion layer 6 are separated by about 0.5-1mum so as to obtain a sufficient withstand voltage.

Filed: 1992-09-03
Abstract: PURPOSE:To improve coordinate instructing resolution by providing a second coordinate analysis mode for performing the coordinate analysis of a second ultrasonic transducer based on the phase of a received signal. CONSTITUTION:In the case of orthogonal detection, continuously received waves Sin (omegat+phi) are divided into two systems, and a transmitting waveform COSomegat and a waveform Sinomegat delaying the phase of this transmitting waveform at 90 deg. are respectively mixed. Then, those waveforms are respectively passed through a low-pass filter LPF so as to provide signals COSphi and Sinphi carrying instantaneous phases, namely, to provide a signal tanphi, the inverse function tan<-1>approx.= is calculated and thus, an instantaneous phase phi is calculated. By successively following up this phase phi, it is judged a manipulator is moved just for one wavelength when the phase phi is once rotated, for example. This phase phican be calculated up to the degree of a 1/20 wavelength, for example, and the moving amount can be more exactly measured in comparison with the conventional system. By accumulating this moving amount, an exact coordinate position can be supported.

IPC: G06T1/60
Filed: 1994-09-30
Abstract: PURPOSE: To output all reception picture data in a storage means for printing even if a page termination signal from a transmission-side is not detected. CONSTITUTION: Reception picture data is once stored in a picture memory 7. CPU 1 registers reception picture data in the picture memory in a state where it can be printed and outputted based on the detection of a page termination signal transmitted from the transmission-side whenever the transmission of picture data for one page is terminated. Even if the page termination signal is not detected in a state where a registration mode is set by a set key 9a, CPU 1 registers reception picture data in the picture memory 7 in the state where it can be printed and outputted. Thus, all reception picture data stored in the picture memory 7 can be printed and outputted.
