Title: Electronic engine optimal control device
Inventor: MATSUI TARO
IPC: F02P5/15
Filed: 1985-04-04
Abstract: PURPOSE:To obtain an optimal operating condition as the whole engine by calculating the rotational energy of an engine crank shaft for each cylinder so as to control optimally the air-fuel mixture ignition means and the fuel supply means on the basis of the calculation result. CONSTITUTION:For each cylinder rotational energy Wn is calculated, and com parison is made with the preceding rotational energy Wn-1. And, when Wn<Wn-1, since the spark advance is in the opposite direction as compared with that in the ignition timing or the fuel supply timing theta0 when the maximum rotational energy W0 is obtained, the direction of spark advance is reversed. And, when Wn>Wn-1, fuel supply quantity Tn and fuel supply timing thetan is output, and the fuel supply quantity is gradually decreased by a minute decre ment DELTAT repeatedly until the rotational energy Wn becomes equal to a basic rotational energy, and when these have become equal the comparison between Wn and Wn-1 as described above is again made to repeat the same procedure. Thus, the ignition timing when the maximum rotational energy W0 is finally obtained becomes in the vicinity of the fuel supply timing thetao in which the operat ing condition is maintained, and accordingly the operating condition at the minimum fuel supply is assured.

Title: Tone control circuit
Inventor: TAKAYAMA KAZUO
IPC: H03G5/02
Filed: 1979-06-07
Abstract: PURPOSE:To emphasize high and low frequency ranges respectively with a single operation knob by varying high and low frequency characteristics by shifting the sliding terminal position of a variable resistor. CONSTITUTION:Between input terminal Ei and output terminal Eo, resistance R1 is connected and both terminals of rotating variable resistance Rv are grounded via low-frequency-range capacitors Cl. One terminal of resistance Rv is connected to output terminal Eo via resistance R1 and sliding terminal S is grounded. Center tap T is connected input terminal Ei via resistance R3 at one terminal and also to output terminal Eo via high-frequency-range capacitor Ch and denoting the angular frequency of the intermediate and high frequency range as omegam results in that 1/ (omegam.Cl)<R2.Rv and 1/(omegam.Ch)>R1.R2 are satisfied. Therefore, since the impedance of capacitor Cl lowers at the intermediate frequency or above, one terminal of resistance R2 is equivalently grounded and the impedance of capacitor Ch is high enough to ignore. Consequently, each frequency range can be emphasized through the single operation of the variable resistance.

Title: Printing head
Inventor: AOKI KENICHI
IPC: C22C38/00
Filed: 1986-03-28
Abstract: PURPOSE:To activate the change of a magnetic flux in a magnetic circuit and to enable the realization of a follow-up response at a high speed, by using a sintered body of powder of silicon and iron in a specified ratio as a material of a yoke, and by setting the density of the material within specified limits. CONSTITUTION:A sintered and formed body of powder of 3% silicon and iron is used as a yoke 5 for a printing head, and it can be made to have an excellent magnetic characteristic equivalent to the one of a magnetically annealed body by setting appropriately the temperature of heat treatment for sintering. Since the density of the material of the yoke can be set at about 6.9-7.1g/cm<3> generally, i.e. lower that of a conventional lost-wax process article or a rolled material, an electric resistance thereof can be increased, and this enables the reduction of an eddy current which is generated in a magnetic circuit at the time of high-speed driving and hinders a change in a magnetic flux. Thereby the rise and fall of a magnetic flux waveform can be expedited, and a residual magnetic flux can be made small. Therefore, the high-speed follow-up operation of an armature 1 is enabled, and a high-speed operation of the printing head is achieved.

Abstract: PURPOSE:To decrease the amount of discharge gas from a getter device, by high-frequency heating a bulb body and then degasing it in a getter flash process by means of which the inner surface of the bulb body is coated by evaporation of the getter agent. CONSTITUTION:A getter device 4 is heated at about 400-900 deg.C for several seconds so as to carry out degasing process, before an exhaust pipe 5 is sealed in the exhaust pocesc of a cathode-ray tube. In this case, the temperature is controlled not to rise up to the temperature at which the getter agent 4b in the getter container 4a starts evaporation. By this degasing, the vacuum degree in the bulb body i s weakened from 10<-6>mm.Hg to 10<-3>-10<-4>mm.Hg, therefore, after degasing, the exhaust of the bulb body 1 is continued until the vacuum degree in the bulb body 1 is recovered, and after the vacuum degree is recovered, the exhaust pipe 5 is sealed. Thereafter, getter flash is conducted in the conventional process by heating the getter device 4 at 900-1,000 deg.C, and the amount of gas extracted from the getter device 4 is very small, the vacuum degree in the bulb (gas ratio) is not weakened, and stable electron radiation can be obtained.

Abstract: PURPOSE:To constitute a titled flaw detector so that its flaw detection impossible range is not increased and an echo is not misconceived by detecting in advance a flaw detecting path, determining a flaw detecting gate time for detecting a flaw, and making total opening time of a position detecting gate means opened successively coincide with the flaw detecting gate time. CONSTITUTION:In a flaw detecting gate time determining means, a flaw detecting depth of a member to be flaw-detected is detected in advance, and also a flaw detecting gate time corresponding to its flaw detecting depth is determined. In a position detecting gate control means, a total opening time of a position detecting gate means is made to coincide with its flaw detecting gate time. Therefore, the position detecting gate means is controlled so that the total opening time of the position detecting gate means is made to coincide exactly with the flaw detecting time determined in advance at every member to be flaw- detected. It is not caused that a flaw detection impossible range and a flaw detection leakage thereby are increased and it is misconceived as a bottom face echo, inspite of a variance of size of the member to be flaw-detected, a change of the quality of material, etc., and an exact ultrasonic flaw detection is obtained.
