Title: Data transfer system for ring-shaped network
Inventor: KAWAHARA NORIAKI
IPC: H04L12/42
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To improve the data transmission efficiency of a ring-shaped network. SOLUTION: This data transfer system is provided with a total size part TS which stores the total size TS(n) of station data added to the data part DT of a transmission frame, wherein each station, when receiving a transmission frame of a 1st round, detects the tail of the data part DT, i.e., the tail of other- station data which is already added according to the total size TS(n) of the total size part TS, adds the data size of its station data to the total size TS(n), and transfers the data. When a transmission frame of a 2nd round is received, data corresponding to the data size of the station data that the station has added are deleted from the head of the data part DT and the resulting data is transferred.  Thus, each station can recognizes a data storage position or deletion position, so each station need not be informed of the storage position or deletion position of data in advance, and the transmission efficiency of a network is therefore improved.

Title: Magnetic recording medium and production thereof
Inventor: KOYAMA NOBORU
IPC: C09D127/06
Filed: 1989-03-31
Abstract: PURPOSE:To improve frequency characteristics and to obviate the generation of drop-out in recording signals by forming a 2nd magnetic layer to have a slightly higher coercive force, satisfying a specific relation between the same and the coercive force of a 1st magnetic layer and providing a mixed region of both thereof between the 1st magnetic layer and the 2nd magnetic layer. CONSTITUTION:The coercive force (Hc2) of the 2nd magnetic layer is determined as slightly high as 600 to 950Oe and the coercive force (Hc1) of the 1st magnetic layer is determined larger than Hc2. The coercive forces are thus so set as to satisfy 1.0<Hc1/Hc2<=2.0. The relatively weak signals are, therefore, sufficiently maintained by the high coercive force of the 1st magnetic layer and the good reproducing of the recording signals is executed even if a spacing loss arises. Since the coercive force is made high in the 2nd magnetic layer, the good recording and reproducing of signals of short wavelengths are possible. The mixed area is provided to 0.1 to 0.5mum thickness between the 1st magnetic layer and the 2nd magnetic layer, by which the reproducing characteristics of the intermediate frequency are improved and the dropout of the signals is prevented.

IPC: G01N27/409
Filed: 1985-04-18
Abstract: PURPOSE:To prevent the burn and abrupt deterioration of a heating element by setting a reference value for discriminating the absolute pressure in an intake pipe of an engine according to the magnitude of the atm. pressure and stopping the supply of electric current to the heating element when the absolute value in the intake pipe is above the reference value. CONSTITUTION:An atm. pressure sensor 33 is provided to an air-fuel ratio control circuit 32 and the reference value for discriminating the absolute value in an intake manifold 23 according to the atm. pressure is set. On the other hand, an absolute pressure sensor 27 is provided to the manifold 23 and the level output corresponding to the intake absolute pressure in the manifold 23 is generated. The high load is discriminated and the supply of the current to the heating element is stopped when the intake absolute pressure above the reference value is detected by the circuit 32. The atm. pressure decreases in a high place as compared to a low place but the reference value decreases accordingly and therefore the high load condition of the engine is exactly discriminated even in the high place. The abrupt overheating of the heating element is averted by stopping the current supply to the heating element even if the exhaust gas concn. rises higher than the temp. obtd. by the heating element under the high load. The burn and abrupt deterioration of the heating element are thus prevented.

Title: Excimer radiator, its manufacture, its life-time prolongation method and apparatus for performing the method
Inventor: HOFMANN ANGELIKA DR
IPC: H01J61/12
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To elongate the life time of an excimer radiator, by making the content of halogen in its discharge space specific, and by adjusting simultaneously the content of halogen per unit output power density to fall within a specific scope, dependently on its maximum output power density. SOLUTION: In a excimer radiator 11, the continuous consumption of halogen is not performed on the inside surface of its discharge space, rather the saturation of the surface reaction of halogen is recognized as increasing the feeding of halogen its filling gas. Therefore, the elongation of its life time is made possible by increasing initially the concentration of halogen in its filling gas. This saturated concentration of halogen is dependent on both its output power and the area of its discharge space. The saturated concentration of halogen for the inside surface of its discharge space is so set that the content of halogen per 1cm<2> of the inside area of the discharge space is at least 1×10<-10> mol/cm<3> . Since its maximum output power density is reduced when adjusting the saturated concentration continuously, the content of halogen per unit output power density is further adjusted to fall within the scope of 1×m10<-7> mol/ cm<3> -1×10<-5> mol/cm<3> , representing the output power density by the unit of watt per 1cm of the length of the radiator 11 dependently on its maximum output power density.

Abstract: PURPOSE:To enhance the processing accuracy by constituting a heat pipe from a hollow cylinder, which consists of porous substance furnished at the inner wall of a spindle in close contact condition, and a hollow inner cylinder arranged so as to form a vacuum chamber in the hollow cylinder, and by installing a radiating fin at the periphery of the end of the spindle. CONSTITUTION:A spindle 2 in spindle construction of a head stock 1 forms itself one component element of a heat pipe 30 provided with heat pipe function to carry out the heat. Therefore, the rotational friction heat generated at a portion of the front bearing 3, i.e. heat receiving part, heats the working liquid, which fills the working liquid feedback layer in a hollow cylinder 26 consisting of porous substance, as shown by arrow, causing gasification thereof to turn it into vapor, which moves quickly through the action of pressure difference to the end of the spindle 2 equipped with radiating fins 25 via a vacuum chamber 27. It is then cooled through the action of the fins 25 to become working liquid as it was through condensation and moves to the portion of bearing 3 through the capillary action of the working liquid feedback layer of the hollow cylinder 26. This scoops out the rotational friction heat.
