An anisotropic etching is performed on the silicon substrate 31 at an angle theta using the mask material 32 as a mask and groove parts 33 are formed. Impurities 34 of the same conductive type as that of the substrate 31 are ion-implanted into the groove parts 33 using the same mask material 32 as a mask. After that, the mask material 32 is removed and the corner parts 35 on the periphery of an element forming region are made to respectively have a roundness. For making the roundness have, an oxide film of more than 500Angstrom  is formed once by a hydrogen combustion method, and after that, for removing the oxide film, an etching may be performed thereon or an isotropic etching may be directly performed on the surface of the Si substrate 31. An oxide film (insulating film for element isolatio) is flatly buried in the groove parts 33. After then, by forming a gate oxide film 37, a gate electrode 38 and source and drain diffusion layers, an MOS transistor is completed.

Abstract: PURPOSE:To prohibit corrosion by the contact of different metals by using a coating film consisting of a material having nearly the same corrosion potential as the corrosion potential of a protective film to form the part between the edge of a magnetic film and substrate and the end of the substrate. CONSTITUTION:The substrate 1 formed by subjecting an aluminum alloy to Ni-p plating or anodic oxidation treatment is manufactured and the coating film 4 consisting of chromium is formed on the outer peripheral end of the substrate 1.

Title: Reverb unit
Inventor: IMAMURA SEIJIRO
IPC: G10H1/00
Filed: 1988-09-01
Abstract: PURPOSE:To generate an output sound artificially by varying the contents of reverberations, e.g. the continuance of reverberations or the number of reverberations per unit time according to the number of musical sounds. CONSTITUTION:A tone generator 3 generates a musical sound signal based upon various supplied signals and data and a musical sound generation system for 16 channel is constituted by time division processing, thereby generating musical sound signals of up to 16 sounds. The musical sound signal is given reverberation effect by musical instrument reverberation parts 4 and 5 according to reverberations characteristic to musical instruments themselves, i.e. the number of musical sounds generated at the same time. Therefore, the reverberation contents, e.g. reverberation time indicating the continuance of reverberations and reverberation density indicating the number of reverberations per unit time are variable. Consequently, the sound generated when plural musical sounds are generated at the same time can be generated artificially.

Title: Transparent cap for refilling pencil
Inventor: KANEKO YOSHIO
IPC: B43K21/00
Filed: 1998-08-03
Abstract: PROBLEM TO BE SOLVED: To prevent an eraser rubber from becoming qualitatively deteriorated by applying an ultraviolet absorbent to a transparent cap. SOLUTION: An ultraviolet absorbent selectively absorbs the ultraviolet light part of solar rays or an artificial light to convert them to a harmless heat energy. Therefore the ultraviolet absorbent not only prevents an eraser rubber 5 from becoming qualitatively deteriorated but also prevents a resin itself from becoming yellowed or deteriorated mechanically. The eraser rubber 5 is fitted into the rear inside 4a of an eraser rubber support 4 provided in a refill lead tank 3 which slides through a barrel 1 and stores the refill read 2 internally. In addition, a transparent cap 6 covering the eraser rubber 5 is fitted into the rear outside 4b of the eraser rubber support 4. This transparent cap 6 is made of a transparent polypropylene resin, in which the ultraviolet absorbent is dispersed.  Therefore, even when ultraviolet rays are emitted to the transparent cap 6 during carrying a refilling pencil in the pocket of a coat, the ultraviolet rays are shut off by the ultraviolet absorbent applied to the transparent cap 6. Thus there is no fear that the eraser rubber 5 would be qualitatively deteriorated.

Title: Color recording method
Inventor: SAKAI TOSHIO
IPC: G03G13/01
Filed: 1982-12-15
Abstract: PURPOSE:To enable highly efficient recording by charging in reverse direction two photoconductive layers of a photosensitive body made by laminating two photoconductive layers of different photosensitivity on a conductive base body and after exposing signals of three primary colors according to specified arrangement of picture elements, developing with specified coloring toners for each color. CONSTITUTION:Color signals of red R, blue B and green G that constitute color picture signal are converted to on and off of red light by a light emission diode array and the photosensitive body 1 is exposed on picture elements according to arrangement of picture elements. In the picture element exposure, at the position of picture element where charging state of photoconductive layers 1B, 1C is released, the surface potential of the photosensitive body becomes (0). On the other hand, at the position of picture element where exposure is not made, surface potential of the photosensitive body maintains the potential after secondary electrostatic charging. However, surface potential of the photosensitive body after secondary charging is 0V. Accordingly, charge distribution corresponding to picture element exposure is generated in the photosensitive body after picture element exposure, but it does not appear as change of surface potential of the photosensitive body 1. When this picture element exposure is completed, position EB of picture element for blue color signal is uniformly irradiated selectively by blue light.

Abstract: PURPOSE:To reduce the load of a transmission station by detecting a system change code showing a change of the system change by a transmission station and informing the system change to a connecting device in case the connecting device for transmission stations executes the process control in response to the change of the system state. CONSTITUTION:The reception data is given to a transmitter/receiver 31-1 from a transmission circuit 2, and the system state information is stored to a system state memory 31-3 of a memory 31-2 via a signal line 32-1. The system change code is stored to a system change code memory 31-4 via a signal line 32-2. Then the detection is decided for generation of a system change when the difference is produced between the contents of the system change code and those of the preceding time. Then the generation of the system change is informed to a control computer 4 from a signal line 32-3. Knowing the generating of the system change, the computer 4 reads out the contents of a system state memory 31-3 through a signal line 32-4 and studies the factor of the state change of a transmission control system. Then the computer 4 executes the process control according to the factor of the change.
