Title: Control method for air-fuel ratio of engine
Inventor: SATO NOBUHIKO
IPC: F02D33/00
Filed: 1985-06-17
Abstract: PURPOSE:To improve drivability and the economical efficiency of fuel, by a method wherein, when a theoretical air-fuel ratio region is shifted to a lean air-fuel region, operation is effected in a theoretical air-fuel ratio for a set time even after an operation region exceeds a boundary therebetween. CONSTITUTION:A control valve 15, mounted in an increase fuel passage 14, is opened and closed based on the duty value of a signal from a control unit 16. In which case, in a normal operation region, when a rotation speed exceeds a given value and a suction negative pressure is below a given value, operation is effected in a theroretical air-fuel ratio, and when a rotation speed is below a given value or a suction negative pressure exceeds a given value, operation is effected in a lean air-fuel ratio. When a theoretical air-fuel ratio region is shifted to a lean air-fuel ratio region, the control valve 15 is driven by means of a signal, having a specified duty value, so that fuel-air mixture in a theoretical air-fuel ratio is fed continuously for a specified time, and a duty ratio is gradually decreased. This enables ensurance of the economical efficiency of fuel in a condition to ensure excellent acceleration performance through a simple system.

Title: Driving method of thermal head
Inventor: KAWAKAMI TOSHIO
IPC: B41J2/36
Filed: 1983-07-20
Abstract: PURPOSE:To obtain a recording with uniform density regardless of data contents by a method wherein a conducting timing of each block to a thermal element is controled so as not to exceed the preset value by calculating numbers of black data in every block inputted to a shift register. CONSTITUTION:For example, in case of thermal elements which constitute one line are 8 groups, a block counter 2 counts up the number of thermal elements by every one block, and a count output B varies as 0-7. A count output C of black data divided by 1/m varies, for example, as 0-2. After an input of recording data DI by one line is finished, because a strobe changing over circuit 4 energizes a count B block included in every count of count output C, so strobe signals SB1-8 are successively produced at time intervals of 1-3. Accordingly, the number of thermal elements which are simultaneously energized is controled nearly as a constant (m) value.

Title: Bond flux for submerged arc welding
Inventor: KATOU TAKASHI
IPC: B23K35/362
Filed: 1981-08-26
Abstract: PURPOSE:To obtain bond flux which is capable of forming a superior bead free of a pock mark and a pit even during small heat input high-speed welding, by adding an adequate amount of manganese ore to flux after a heat treatment is performed at temperature where the manganese ore is stabilized. CONSTITUTION:This is bond flux obtained by adding 3-70wt% manganese ore, heated at >=1,000 deg.C to 100wt% flux. When ore, containing a large quantity of manganese oxides, such as manganese dioxide ore, rhodochrosite, and manganese silicate ore is heated at >=1,000 deg.C, unstable manganese oxides is transformed into stable Mn3O4, and the water content is reduced. Thus, the manganese ore is made best as a bond flux raw material, attaining the purpose. When the amount of baked manganese ore is less than a lower limit, an improving effect for welding is not obtained and when greather than an upper limit, an arc becomes unstable to deform a bead shape, generating an undercut.
