Patent JP-2000340525-A (JP)
Title: Semiconductor manufacturing apparatus and manufacture of semiconductor device
Inventor: TAKASE TAMAO
IPC: H01L23/52
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To enable a metal plating film to be subjected uniformly to CMP processing in an after process by a method, wherein the metal plating film buried in an insulating film to serve as a wiring material is formed uniformly on a semiconductor substrate. SOLUTION: Fine obstacles 7 used for making a plating rate uniform are provided between an anode 3 and a cathode 4 mounted with a semiconductor wafer 1, which are arranged in the plating tank 2 of a plating device. When plating operation is carried out by the use of a plating solution loaded with leveler, an obstacle is arranged at a groove. In a plating method, a plating solution contains a leveler as an additive which has an effect of making a film forming speed on a flat part slower than that on a groove so as to be improved in embedding properties, so that a plating solution is turned reverse in pattern-dependent properties, and a film forming speed becomes higher at a narrow groove. An obstacle is arranged at a proper position on the wafer 1, with which a plating film of uniform thickness can be grown.
Patent JP-H098791-A (JP)
Title: Method and circuit for synchronizing multiframe
Inventor: USU KATSUNORI
IPC: H04J3/06
Filed: 1995-06-19
Abstract: PURPOSE: To prevent erroneous synchronism acquisition in a multiframe synchronizing system. CONSTITUTION: Matching between the frames of serially transmitted received data is discriminated for the unit of a bit and concerning the matching bit, '+1' is inputted but concerning the non-matching bit, the output result of a selector 11 is inputted to an adder 4 and accumulated. When establishing synchronism from an asynchronous state (in a synchronism hunt mode), the selector 11 selectively outputs a rear protection step numerical value ('-7') but in the case of transition from a synchronism established state to the state out of synchronism (in a synchronism protection made), a front protection step numerical value ('-2') is selectively outputted.  Thus, when the bit between the frames is not coincident in the synchronism hung mode, the accumulated value of the adder 4 is reset so that only the accumulated value of the matching bit can be enlarged and probability for acquiring synchronism by pulling in any bit excepting for the synchronous bit can be reduced.

Title: Catalysis apparatus without space piece
Inventor: MORITA ISATO
IPC: F01N3/28
Filed: 1977-12-19
Abstract: PURPOSE: To provide a catalysis apparatus ideal for exhaust gas containing much dust by means of a passage for gas containing NOx formed with unit catalysts on bent plates assembled at a given space without use of spacers.  
     CONSTITUTION: A thin plate is protruded from the reference plane and coated with a catalyst component on the surface to form a unit catalyst 1. The unit catalysts are arranged to form channels with a U-shaped section. The channels are fixed facing each other and connected together with metal fittings to form a plurality of gas passages with less resistance to a gas stream containing NOx. The catalysis apparatus without space piece can resist to bending. Thus, the apparatus itself constitutes a sturdy construction. The bent plates can be worked easily with a press or the like thereby facilitating the assembly of the apparatus.

Abstract: PURPOSE: To obtain a magnetic head having a life detecting means capable of electrically and exactly knowing the life (wear-out limit) of a head part. CONSTITUTION: The constituting member of the head part, for example, a gap space 7 forming a magnetic gap by being held between a pair of magnetic cores 3 and 4 is formed out of a conductive material 7a having insulating layers 7b formed on both surfaces. This gap spacer 7 is provided with a life detecting part 11 to be cut by the friction of the head part in a position (h) shallower than the effective depth (d) from the surface of the magnetic gap for sliding contact with a magnetic medium 2.

Title: Top cowling for outboard engine
Inventor: YONEZAWA TORU
IPC: F02M35/12
Filed: 1984-07-20
Abstract: PURPOSE:To obtain a cowling construction which is effective for a Diesel engine having a large low frequency noise by forming a cowling as a whole into an expansion type muffler which greatly damps down a sound of low frequency. CONSTITUTION:Intake air from an air intake 7 gets out in the right and left directions from a gap between an upper cowling 6 and a ceiling plate 34, passes through both sides of a recessed part 37, and is discharged from intake air outlets at the center and on both right and left sides, toward intake pipes 8, 8 sides. On the other hand, the sound of intake air given forth from the intake pipes 8, 8, is outwardly released through an intake air introducing passage 35 after once discharged into the space 9 of a top cowling 4. This process as a whole constitutes an expansion type muffler which greatly damps down a sound at a low frequency range, thereby, sufficiently muffling a low frequency sound. Accordingly, an outboard Diesel engine with low noise can be obtained, as a cowling construction which is effective for a Diesel engine with a large low frequency noise.

Title: Fuel injection device in rotary engine
Inventor: YAMADA MINORU
IPC: F02B53/10
Filed: 1979-11-23
Abstract: PURPOSE: To provide a satisfactory mixture of fuel and air particularly in low speed to improve fuel consumption by dividing load and rotational frequency of an engine into a plurality of ranges and allocating the respective ranges to each injection valve to reduce the capacity of each injection valve and prolong injection time.  
     CONSTITUTION: The second throttle valve 6 is fully closed under low load condition so that intake air cannot pass therethrough, but flow all to a second intak  branch pipe 12. Since then intake paths are formed with a section smaller than that  of one intake path, flow speed is higher. Also, under low speed and load condition  is injected fuel from the second fuel injection valve 13 having capacity of fuel injection per one valve smaller than that of the prior one to inject same amount of fuel  as the prior one so that injection time is elongated and flow speed is heightened  while droplets of fuel liquid are pulverized to be mixed sufficiently with air and  atomization is promoted.

IPC: F25B39/00
Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To disturb the concentration boundary layer and promote diffusion of material so as to enhance the heat transfer coefficient by forming weirs having protruding cross section on the inner surface of a pipe in a circumferential direction thereof at a given interval and forming grooves which restrict the flow of a non-azeotrope refrigerant between weirs in such a manner that their angles are different from each other. SOLUTION: On an inner surface 2 of a heat transfer pipe 1 provided with inner surface grooves, a large number of protruding ridges 4 are formed to provide a plurality of grooves 3. Furthermore, on the inner surface 2 of the pipe 1, weir 5 having protruding cross section are formed in a circumferential direction at a given space. The grooves 3 are formed such that using the weir member 5 as a boundary, the grooves formed at one side and located adjacent to the weir member 5 have their lead angle set at 4 deg. to 45 deg., while the grooves formed at the other side and located adjacent to the weir member 5 have their lead angle set at -4 deg. to -45 deg..  Due to such a construction, the weir member 5 can change the flow of non- azeotrope refrigerant in a direction perpendicular to the direction of the pipe axis and the grooves 3 which differ in direction from each other further promotes its agitation. Accordingly, the concentration boundary layer is disturbed and the diffusion of material is promoted thus enhancing the heat transfer coefficient.
