Title: Control device for two-cycle internal combustion engine
Inventor: SUGIMOTO ATSUSHI
IPC: F02D41/18
Filed: 1992-03-10
Abstract: PURPOSE:To suitably perform various controls of an internal combustion engine by detecting the opening/closing timing of a reed valve for opening/closing an intake air passage in the internal combustion engine, and calculating an intake air amount based on an operational condition of the internal combustion engine in this opening/ closing timing, so that the intake air amount is easily and accurately calculated. CONSTITUTION:In a crank chamber prepressurizing 2-cycle internal combustion engine M1, operation is controlled based on an intake air amount supplied to a combustion chamber from a crank chamber. Here, an intake air passage communicating with the crank chamber is opened/closed by a reed valve M2. Opening/closing valve timings of the reed valve M2 are respectively detected by an opening/closing timing detecting means M3. Further, each operational condition of the internal combustion engine M1 in the opening/closing timing of the reed valve M2 is detected by an operational condition detecting means M4. In accordance with the operational condition of the internal combustion engine M1 detected in the opening/closing timing of the reed valve M2, an intake air amount is calculated in an intake air amount calculating means M5. In this way, the accurate intake air amount is obtained by a simple constitution, thus to suitably perform various controls of the internal combustion engine M1.

Abstract: PURPOSE:To produce sintered body having a hollow hole of high inside surface accuracy by providing a bulging part corresponding to a thick-walled part to the outside circumference of a core rod to be used for production of the sintered material having the hollow hole provided with the thick-walled part on the outside part. CONSTITUTION:A lower punch 3 is inserted into the molding cavity C of a molding 1 and the core rod 4 with a main shaft 4A faced upward is inserted into a through-hole 3a thereof. Raw material powder for sintering is then put into the cavity C and the main shaft 4A is inserted into the through-hole 2a of an upper punch 2 so that the powder is compacted by the punches 2, 3 and the molding A1 having the thick-walled part 10'a is formed. The bulging part 4b is provided on both sides in the diametral direction to the part of the rod 4 corresponding to the thick-walled part 10'a to form said part into an approximately elliptical shape and therefore the elliptical recess is formed on the inside surface of the molding A1. The molding A1 is thereafter sintered, then the thick-walled part 10'a expands more largely than the other part and bulges therefore toward the inside to make round the elliptical recess. The sintered material having the hollow hole of high accuracy is thus obtd.

Title: Manufacture of semiconductor device
Inventor: IDA JIRO
IPC: H01L21/28
Filed: 1987-03-09
Abstract: PURPOSE:To prevent the surface from being oxidized and from being roughened as well as to reduce the sheet resistance by selecting the ratio between a thickness of high-melting point metal film and that of amorphous silicon film, thereby leaving a silicon layer on a silicide surface even after the silicification reaction. CONSTITUTION:On a ground 11, a high-melting metal Ti 12 and an amorphous silicon a-Si 13 are deposited. Now, the film thickness of the Ti 12 is set to 500Angstrom  and the film thickness of the a-Si is set to 2000Angstrom , and they are annealed in a nitrogen atmosphere. Consequently, the Ti 12 and the a-Si 13 react with each other to form a silicide 14, but a-Si layer 15 comprised of the remaining a-Si 13 is left on the silicide 14 even after the reaction. If the ratio of the film thicknesses of the Ti 12 and a-Si 13 is selected as this, the Si layer can be left on the silicide surface even after the silicification reaction. With this, the oxidation of the upper surface of the silicide is prevented and the roughness of the surface is improved, and also the sheet resistance can be reduced.

Title: Electrifying member and image forming device using the same
Inventor: ISHIHARA TOMOJI
IPC: G03G15/02
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To obtain a high-speed, long life electrifying member suitable for obtaining high image quality by forming an activation surface on the outermost surface of base material constituting the electrifying member obtained by known means and materials in the conventional manner. SOLUTION: This electrifying member 2 has a compound layer structure consisting of a conductive core bar 2a, a conductive elastic layer 2b made of conductive rubber and molded like a roller by die molding so as to be concentrically integrated with the core bar 2a, and a surface layer 2c formed on the outer periphery of the layer 2b. As a method for forming the activation surface, polymerization reaction (surface polymerization) of the surface of the base material and contact with acid, alkali and moleculars in an excited state are mentioned. Thus, even in the case of a material having high releasing property, the activity of the outermost surface of the base material is enhanced by reforming the surface of the material and introducing a polar group in particular, whereby sufficient adhesiveness with another layer is obtained.  Therefore, adhesion of developer, etc., is prevented to provide high quality even in the case of requiring a high speed operation and extension of service life.

Inventor: MIZUGUCHI HODAKA
IPC: H04N19/60
Filed: 1993-03-12
Abstract: PURPOSE:To perform efficient encoding and to reduce the scale of hardware. CONSTITUTION:In the sub-band encoding system of pictures, it is normal to make the ratio of a sub-sampling cycle and the sampling cycle of input data smaller than the tap number of a band dividing filter so as to make quantization distortion inconspicuous. As a result, the absolute values of respective band components become large at the edges of a screen and efficient data compression is interfered. Thus, endless scanning for passing through entire picture elements inside a frame or a field only once is performed, the edges of the screen are equivalently eliminated and sub-band encoding is performed for data strings obtained as the result.
