Title: Cylinder fuel injection type internal combustion engine
Inventor: ANDO HIROMITSU
IPC: F02F1/42
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To collect rich mixture in the vicinity of an ignition plug so as to ensure combustion stability by arranging a crest part which consists of a flat plate shaped inclining surface adjacent to a lower surface of a cylinder head and a side wall surface heaved from a recessed part, on a piston. SOLUTION: When compression of a piston 2 is completed, a compact combustion chamber is formed between a piston recessed part 24 and a side wall surface vf, and a lower wall surface 6 opposed to a cylinder. Fuel injected into the combustion chamber collides with the recessed part 24 or/and the side wall surface vf, and fuel atomization after collision performs fluid motion along the side wall surface vf. A crest part 232 of a connecting end of both wall where the side wall surface vf and an inclining surface 231 are intersected with each other, is formed in an edge shape, separation of fuel is improved, and fuel flows out so as to splash away toward an ignition plug 20 arranged on a position opposed to the crest part 232. Reverse tumble flow TF formed in the combustion chamber restricts fluid motion of fuel atomization which collides with the recessed part 24 or/and the side wall surface vf so as to guide fuel atomization to the ignition plug 20 surely.

Abstract: PURPOSE:To eliminate the deterioration in voltage resistance and to attain high integration by a method wherein the surface of an epitaxial layer in a position wherein a diffused layer of P-type or N-type impurities is to be formed is etched prior to the formation of the diffused layer, so as to reduce the thickens of the epitaxial layer sufficiently, and thereafter the introduction of the impurities and heat treatment of high temperature are conducted. CONSTITUTION:Impurities of high concentration having a couductivity type opposite to the one of a semiconductor single-crystal substrate 1 are introduced into the surface of the substrate, and an epitaxial layer 2 having a conductivity type opposite to that of the substrate is formed thick thereon. Next, the surface of the epitaxial layer in a position wherein a diffused layer for element isolation is to be formed is etched to form a recessed portion 4. Then, impurities having the same conductivity type as the substrate are introduced Into a region wherein the recessed portion is formed, and thereafter heat treatment of high temperature is applied to form the diffused layer 3 for element isolation which is deep enough to reach the substrate. On the occasion, the impurities introduced into the surface of the substrate are also diffused by the heat treatment, so as to form a buried layer 5. Subsequently, element formation layers 6 and 7 are formed by diffusion in the epitaxial layer isolated by the diffused layer. Since the time for heat treatment of high temperature can be shortened by this method, the rise up of the buried layer is reduced and the deterioration of voltage resistance can be prevented in the case of an element of high voltage resistance which has a thick epitaxial layer.

Filed: 1982-05-07
Abstract: PURPOSE:To obtain a firm emission-tube supporting structure which can be manufactured easily by making an emission tube to be supported by and fused to a stem through a cylindrical sleeve. CONSTITUTION:A stem 2 is provided with sealing wires 7. An emission tube 3 is sealed with another stem 31, and a concave rib 32 is formed on the fused surface between the emission tube 3 and the stem 31. At first, a sleeve 6' is attached around the emission tube 3 and lifted above. Then sealing wires 81 supporting an electrode 4 and the sealing wires 7 of the stem 2 are joined together by a means such as welding. Next, the sleeve 6' is moved down, and the end of the sleeve 6' is fused to the stem 2. As a result, a rib 61 provided on the sleeve 6' is connected to the emission tube 3, causing the sleeve 6' and the emission tube 3 to be firmly fixed together. Owing to such a constitution, since the emission tube 3 is supported not only by the sleeve 6' but also by sealing wires 82 and 7, the strength of the emission-tube supporting structure is remarkably increased. Therefore, there is almost no need to use an adhesive in sticking the sleeve 6' and the stem 2 together.

Abstract: PURPOSE:To read a memory by a stable clock not to be affected by an input signal by interrupting the output of a phase comparator when a freeze picture is reproduced and impressing a fixed direct current bias voltage to the following part of a low-pass filter part. CONSTITUTION:At the time of special reproducing freeze, a movable terminal 3c of an analog switch 3 is changed over to a fixed terminal 3b side by a control signal CH and the output of a phase comparator 2. Then, a fixed bias value to be outputted from a direct current constant voltage source 9 is inputted through the analog switch 3 to the following part after a low-pass filter 4. Accordingly, at the time of the special reproducing freeze, a memory reading clock c1 is set in a free-run state to an input video signal. When the freeze picture is reproduced, only the reading operation of picture data written to a frame memory is executed and writing operation is not executed. Accordingly, it is not necessary for the memory reading clock ck to be synchronized to the input video signal at the time of the freeze.
