Title: Mobile communication cipher key distributing method
Inventor: ISHII DAISUKE
IPC: H04W12/04
Filed: 1999-09-20
Abstract: PROBLEM TO BE SOLVED: To distribute a new group cipher key when group members increase or decrease even if a radio transmission line is unstable enough to cause an error or there is a terminal not in opreation. SOLUTION: For the distribution of a group cipher key by a Burmester- Desmedt, virtual dummy members corresponding to group members are provided for a base station and group array constitution having group members between the dummy members is obtained. When a new group member is added, new dummy members is generated to put the new group member between them, and parameter information on the dummy members before and after it is broadcasted from the base station. When a group member is deleted, parameter information on the precedent and following dummy members is corrected at the base station and broadcasted. A member terminal calculates a common key from the new parameter information.

Title: Method for removing plating scrap in plating tank
Inventor: ITO KIYOSHI
IPC: C23F1/18
Filed: 1993-09-30
Abstract: PURPOSE:To easily dissolve off depositing plating scrap by introducing an aq. ammonim persulfate soln. of specified concn. with the pH regulated by sulfuric acid into a plating tank in which plating scrap deposits. CONSTITUTION:An aq. soln. contg. 5-15wt.% ammonium persulfate and regulated to pH2 with sulfuric acid is prepared. The soln. is sent into a plating tank in which metallic plating scrap deposits by a pump, kept at about 20-50 deg.C and agitated while blowing air into the soln. to dissolve off the scrap. Consequently, the metallic plating scrap depositing on the wall of the plating tank, the surface of an attached roller, etc., is dissolved off without generating harmful gas.

Title: Gas catalytic heater
Inventor: KAINO KIKUO
IPC: F23D14/18
Filed: 1984-12-17
Abstract: PURPOSE:To stabilize catalytic combustion in a gas catalytic heater, by positively bringing gas into a catalytic reaction without burning of gas on the pilot gas burner, by once shutting off a pilot gas after a catalyst is preheated by the flames of a pilot burner, and then by injecting gas from a main nozzle. CONSTITUTION:When an operation switch 7 is pushed to the upward direction as shown by an arrow sign A, a pilot gas lever 10 is pushed up, at the same time, gas is started injecting from a pilot burner 5, and a catalyst 4 is preheated into red-heated state by pilot gas flames ignited by sparks discharged from a high voltage generator 6. At this time, a main gas nozzle 2 is held in a closed state, as a compression spring 13 is provided to a switch 8. Then when the operation switch 7 is depressed to the direction shown by an arrow sign B, the slot gas is shut off, and after that, a main gas lever 9 is forcibly depressed by the main switch 8 against the depression spring 13. On the contrary, the main nozzle 2 is brought into an open state by the depression force of a nozzle spring 12. Injected gas is all brought into catalytic reaction, because no gas flames will remain around the main nozzle 2.

Title: Individual ignition method
Inventor: ASANO MORIHITO
IPC: F02P7/077
Filed: 1994-10-28
Abstract: PURPOSE: To omit a sensor for cylinder determination so as to simplify a sensor constitution by carrying out ignition in both timing at a compression top dead center and a discharge top dead center of an engine with odd-numbered cylinders. CONSTITUTION: In an engine with odd-numbered cylinders, P signals outputted from a crank angle sensor 11 are inputted at equal intervals into an electronic controller 4 in the position having teeth 13a sequentially, while in the position having no tooth 13a, an inputting interval for the P signal is doubled, so that an arrival of a piston of the first cylinder at a top dead center is determined by measuring the P signal inputting interval. Subsequently, a top dead center in each cylinder is determined on the basis of the top dead center of the first cylinder. At both of a compression top dead center and an exhaust top dead center in each cylinder, ignition is carried out, and the top dead centers in a compression stroke and an exhaust stroke are determined on the basis of a rotational change condition after ignition.  In this way, ignition is carried out in both of the top dead centers until the compression top dead center and the exhaust top dead center after a start of the engine are determined, so that complicated constitution required for determining a cylinder can be omitted.

IPC: H01L27/10
Filed: 1999-09-20
Abstract: PROBLEM TO BE SOLVED: To secure the prescribed write-in margin by preventing occurrence of level variation of a bit line caused by a coupling noise between bit lines. SOLUTION: When a memory cell cell is not selected, a recover bar signal is low, NOR circuits 4, 5 are low, PMOS transistors T4, T5 are turned on, and bit lines BL, BL bar are pre-charged. After that, when NMOS transistors T1, T2 are turned on by a column selecting signal and a memory cell is selected, a recover bar signal is made high, while a write-in pulse signal and write-in data are inputted to NAND circuits 1, 2, for example, in order to make data lines 50, 50 bar a low level or a high level, the NOR circuit 5 is kept as it is, but the NOR circuit 4 is made a high level. Thereby, the bit line BL bar is fixed to a VDD level keeping the T4 as it is. A T3 is turned off and the bit line BL is made a low level, but a level of the BL bar is not varied by a coupling noise at the time.

Title: Method and apparatus for measuring degree of rubber vulcanization by ultrasonic wave
Inventor: TAKAMURA KENJI
IPC: G01N29/00
Filed: 1987-10-23
Abstract: PURPOSE:To measure the degree of preceding in the vulcanization of rubber, by applying an ultrasonic wave to rubber fed with a fixed pressure to read a supply power to an ultrasonic vibrator necessary for keeping amplitude constant. CONSTITUTION:A rubber sample S is placed between a phone 3 for guiding an ultrasonic wave from an ultrasonic vibrator 2 and a pressure plate 8 of a pressurizing mechanism 7 to feed a fixed pressure thereto. An ultrasonic wave from the ultrasonic vibrator 2 is guided to the sample to detect amplitude thereof with an ultrasonic sensor 4. Then, A detection value from the sensor 4 is compared with a reference value previously set to control an output of a high frequency power source 1 with a control section 5 so that a deviation therebetween will be zero, that is, the amplitude of the ultrasonic wave is always at a fixed value. As a damping force of the rubber sample S relative to the ultrasonic wave is in a close relation with the degree of preceding in the vulcanization of the rubber, the degree of preceding in the vulcanization of the sample S can be measured by gauging a supply power to the ultrasonic vibrator 2 with a meter 6.
