Title: Air-fuel ratio control device
Inventor: ASANO MASAHARU
IPC: F02D41/14
Filed: 1983-09-29
Abstract: PURPOSE:To enhance the controlling performance and the exhaust gas purification characteristics by adding a dither signal to control signal, while feedback control of the air fuel ratio is off, and by oscillating the mixture gas between the rich and lean sides. CONSTITUTION:Output signal from an exhuast gas sensor is fed into the input terminal 8 of a deviation sensing circuit 10. A control signal is placed out at the output terminal 9 by using operational amplifiers 13-15. A circuitry from diode D1 to comparator 18 constitutes a judgement circuit to judge if there is any abnormality in deviational signals. When a switch 53 in a switching circuit 17 is turned on, a dither signal from a dither oscillator 16 is added. Thereby, start and stop of the feedback control of air fuel ratio can be controlled certainly, which ensures that the controlling performance and exhaust gas purification characteristics are enhanced.

Filed: 1992-07-07
Abstract: PURPOSE:To provide a gas disconnecting switch of high reliability by reducing the rate at which resistors for reducing excess voltage are exposed to cracked gas, thereby securing the long-range reliability of the resistors. CONSTITUTION:A flage portion 6a is formed integrally with the base portion of a fixed electrode 6 and a plurality of resistors 8 are disposed concentrically with the fixed electrode. The end of each resistor 8 is projected toward a movable electrode 9 and is provided with a columnar metal conductor 31. Eight metal conductors 31 are provided at equal intervals and concentrically with the fixed electrode 6 and a ventilating opening for discharging cracked gas is provided between adjacent metal conductors 31. A shield 7 at the end of the fixed electrode is connected to the end of each metal conductor 31. When restriking takes place between the poles on operation of a disconnecting switch, an arc 25 is re-ignited. Then cracked gas generated diffuses into the disconnecting switch through the ventilating opening of the metal conductor 31 and its concentration is remarkably decreased. Therefore, the resistors 8 are not exposed to the cracked gas of high concentration.

Title: Pneumatic radial tire having high durability in bead portion
Inventor: IIDA HIROYUKI
IPC: B60C15/06
Filed: 1988-07-21
Abstract: PURPOSE:To enable secureness of durability in a bead portion required for elongation of regenerative lifetime of a heavy loaded radial tire by constituting a carcass profile in such a way as to generate a compressive stress in the bead portion near the winding-up end of a ply together with deformation of a carcass with a standard inner pressure filled. CONSTITUTION:The curvature varying region (upsilon) of a carcass passline bypasses toward the winding-up portion of a ply at a self-standing attitude filled with 5% of a standard inner pressure under an unloaded condition with rims braided. Under such a condition that the standard inner pressure is filled as shown by a dashed line, the passline of a carcass 4 deforms smoothly and continuously together with the expansion deformation of a tire on the basis of the inner pressure so that a compressive stress is generated inside a bead portion 1 near the winding-up end of the ply, thereby decreasing tensile strain. The compressive stress reduces the tensile strain under the unloaded condition with the inner pressure filled so as to bring about effective reduction of the tensile strain in the winding-up end of the ply in the bead portion at the time of traveling of the tire, thus suitably avoiding any trouble in the bead portion.

Title: Integrated circuit for combustion control
Inventor: TOUDOU KENJI
IPC: F23N5/00
Filed: 1983-09-30
Abstract: PURPOSE:To prevent chattering in the outputs generated at times of supplying and stopping of power, by providing a power voltage detecting circuit to output a signal which resets a logical circuit under the voltage lower than the reference voltage, but higher than the operation starting voltage for the logical circuit and a linear circuit. CONSTITUTION:When the power voltage is low at the starting time of power supply, the internal resistance is very high in the group 2 of diodes in a power voltage detecting circuit 21, so that most current flowing through a resistor 1 is to become the base current for an NPN transistor 3. But its output from an emitter is divided into a resistor 4 and a resistor 5. Since the divided voltage is to become the base voltage for an NPN transistor 6, it continues cut off state because of too low base voltage, and the output from the power voltage detecting circuit 21 becomes ''L'' level, so that a counter 23 and R-S flip flops 24 and 25 in a logical circuit 22 are reset. Therefore, the group 27 of output terminals in a linear circuit 26 are held on ''H'' level. When the power voltage exceeds a predetermined voltage, the output from the initialized circuit 21 turns to ''H'', and it releases the reset state of the logical circuit 22. By releasing reset, the logical circuit 22 starts operation based on a signal from a linear circuit 28 for input interface, putting out sequential signals to the group 27 of output terminals.

Title: Mechanical translation device
Inventor: KUGIMIYA HIDEZO
IPC: G06F17/28
Filed: 1989-07-12
Abstract: PURPOSE:To produce a natural translated sentence by outputting a translated word consisting of the characters of the same type as those characters of the translated word of the basic word including a prefix when this prefix included in a source language is translated. CONSTITUTION:An input sentence is divided into the morpheme strings by a dictionary consulting morpheme analyzing part 11 for acquisition of the translated words, etc. Then a sentence structure obtained via a sentence structure analyzing part 12 is converted into the sentence structure of a desired language via a conversion part 13. Then a translated sentence is obtained via a translated sentence production part 14. If a morpheme inputted from the part 13 is discriminated as a basic word including a prefix, the types of characters forming the translated basic word are discriminated by a character type discriminating means. Thus a translated word of a prefix consisting of the characters of the same type is produced based on a prefix table. Therefore a translated prefix is produced with the characters of the same type as the translated basic word. In such a way, a natural translated sentence is obtained.
