Title: Equipment for recording-regenerating static picture
Inventor: FUJIME TOSHIROU
IPC: G11B20/02
Filed: 1980-11-10
Abstract: PURPOSE:To obtain pictures having no unevenness in the brightness, by performing recordings and regeneratings in such a way that wow and flutter components of the floppy disk recorder can be reproduced in the regenerated output. CONSTITUTION:Video signals input into a terminal IN are impressed upon an A/D converting circuit AD. The video signal is quantized by the circuit AD and written into a field memory VM. Contents of the memory VM are immediately converted into time base extending signals, and then, written into a floppy disk recoder FDD through an FM modulator FM. Regenerated outputs of the recorder FDD are demodulated at an FM demodulator DM, and wow and flutter components are detected. These components are added to a differential amplifying circuit DF together with outputs of a clock pulse demodulator KM, and variations in amplitude of the luminance signals are compensated by countervailing the wow component.

Title: Manufacture of non-volatile semiconductor memory device
Inventor: YAMAGATA YASUJI
IPC: H01L29/792
Filed: 1988-06-27
Abstract: PURPOSE:To enable a large-scale EPROM cell array with a short access time to be manufactured by driving an n-type impurities into an area directly below a drain diffusion layer and a source diffusion layer except the area near a double-gated channel area by the ion implantation method with a double-gate electrode and a side wall as a mask. CONSTITUTION:A photoresist is eliminated, arsenic ions are implanted into an oxide film 30 by a thermal oxidation method, and a drain diffusion layer 31 and a source diffusion layer 32 are formed in self-alignment with a gate electrode. Then, an oxide film is accumulated over the entire surface of substrate by the gaseous phase growth method and a proper anisotropic etching is performed to allow a side wall to be formed on the side surface of the gate electrode. Then, an n-type impurities, for example phosphor, is driven into an area directly below the drain diffusion layer and the source diffusion layer excluding the area near a channel area by the ion implantation method with the gate electrode and the side wall as a mask. Then, without changing the conduction type of this area and by making low the concentration of impurities of the area, a low-concentration P-type area 34 is formed (This low-concentration P-type area will not be formed near the channel area of a transistor).

Title: Manufacture of diffraction grating
Inventor: SHIRASAKI MASATAKA
IPC: G02B5/18
Filed: 1985-07-17
Abstract: PURPOSE:To simplify extremely handling by manufacturing previously a diffraction grating with a phase difference and taking it for a mask. CONSTITUTION:The mask 14 with the diffraction grating 16 on the surface is contacted to a photoresist on an InP substrate 13. When an S polarized light is made incident as an exposure light beam 15, it is split into a transmitted light beam 17 and a primary diffracted one 18, both of which orient the substrate 4 with the same intensity and the same emitting angle to form a diffraction grating pattern on the substrate 4. Here, when the phase of the diffraction grating 16 on the mask 14 is delayed by 1/2 pitches at a position C corresponding to a stage part 11, the phase of the transmitted light beam 17 is constant, however, that of the diffracted light beam 18 is inverted. Moreover the diffraction grating pattern on the substrate 4 develops a phase shift. Thus the diffraction grating with a lambda/4 shift made of DFB laser can be obtained.
