Title: Structure for fixing solenoid valve on carburetor
Inventor: NIITSUMA SHIGETO
IPC: F02M19/02
Filed: 1981-05-15
Abstract: PURPOSE:To prevent the load in the vertical direction from concentrating on the insulating plate in such a way that vertical external force of a solenoid valve is restricted from moving in the counterdirection in the vertical directions by means of the tangential contact to the horizontal through an O-ring. CONSTITUTION:An insulating plate 5 is tightly fixed in the tangential contact on the outer bottom side of a choke chamber 1 in the condition that the diametral contracting part 23 is formed on the upper end side of an inserting hole 20 of a choke chamber 1 to the outer peripheral part 19 at the upper part of an solenoid valve 3, and the upward displacement is engaged in the tangential contact of the tip on the rim of the outer cylindrical part 19 at the diametral contracting part. The horizontal of the stepped part 21 which is formed at one part of the upward inner bottom side of a float chamber 2, and the end side of the outer peripheral stepped part 24 of an outer cylindrical part 14 are tangentially contacted together through a resilient O-ring 25 at the lower part of the solenoid valve 3. The solenoid valve 3 can be entirely prevented from concentrating the load in the vertical directions to the insulating plate 5, because the movement in the mutual counterdirections to the vertical directions is restricted by the tangential contact at the horizontal to the upper end of the rim of the outer cylindrical part, and the diametral contacting part 23 of an inserting hole 20.

Title: Phase difference detecting method
Inventor: SHIRAHAMA HIDEFUMI
IPC: H03L7/08
Filed: 1985-04-08
Abstract: PURPOSE:To execute the digital circuit by detecting the phase difference of the first and second input signals with a difference in pulse width between the first output pulse to start by the first input signal and stop by the second input signal and the second output pulse to output each time the first output pulse occurs. CONSTITUTION:When the first signal and the second signal are input signals 11 and 12, a signal 13 goes to be the signal in which the High and Low of the signal 12 is made reverse, and the first output pulse 14 goes to be high by the rise of the signal 11 and Low by the fall of the signal 13. Signals 15 and 16 are changed over by the rise of the signal 13 a signal 19 goes to be High by the rise of an AND signal 17 of signals 14 and 15 and Low by the rise of the signal 15. Since an AND signal 18 of signals 14 and 16 will not rise, a signal 20 is Low as it is. Consequently, an output signal 23 of an OR circuit 10 is made at output signals 21 and 22 of three input AND circuits 8 and 9, and goes to be the second output pulse. Thus, the phase difference of input signals 11 and 14 is obtained as difference in pulse width between output signals 14 and 23.

Title: Fuel injection nozzle in diesel-engine
Inventor: SAEGUSA SHIYOUGO
IPC: F02M45/08
Filed: 1983-04-27
Abstract: PURPOSE:To make it possible to obtain a satisfactory characteristic of fuel injection over an entire range, by providing the first and second high pressure fuel passages to prevent the prolonging of period of fuel injection in a high speed and high load range while aiming at reducing the initial fuel injection rate. CONSTITUTION:When fuel pressure exceeds a predetermined value, a needle valve 4 lifts while pushing up a central plunger 11. In this state, the overlapped area between an oil hole 11a and an annular groove 1a is reduced accompanied with the increasing lift of the needle valve 4 so that the pressure of fuel injection lowers. Thereby the needle valve 4 again descends to repeat the increase of the above-mentioned overlapped area so that the injection is carried out at a low injection rate, and when the fuel pressure further increases, the injection is carried out at a high injection rate with the high pressure fuel alone. In accordance with the high speed rotation of the engine, the period of the initial fuel injection through a passage 1b at a low injection rate becomes short, thereby the initiation of the main fuel injection through a passage 1d is promoted.

Title: Measuring circuit for operating time of multiple contacts
Inventor: MATSUBARA YUUSAKU
IPC: G04F10/04
Filed: 1982-04-28
Abstract: PURPOSE:To reduce the number of constituting elements and to simplify the constitution of an IC circuit for measuring the operating time of multiple contacts by applying the output of a counter for measuring time directly to a memory and controlling the writing to the memory according to the change in the plural input signals. CONSTITUTION:When contacts operate, the input signals I1, I2- thereof change from H to L, and the pulse outputs of a specified width are generated from corresponding FFs 21- and pulsing circuits 31- and are made into the writing control signal to a memory 5 through a multiplexer 4. The memory 5 writes the output of a counter for measuring the time applied directly into the address assigned by the counter 6 and the operating time of the contacts is measured and stored. Therefore, if the output of the counter for measuring time is latched in parallel at each of the contacts and is compared with the output of the case when the output is written into the memory through a switching element, the number of the constituting elements is reduced, and the constitution of an IC circuit for measuring the operating time of the multiple contacts is simplified.

The transmission shafts 10c, 20c, and 30c are positioned concentrically. Thus, the size of the transmission shaft is increased in order of 10c, 20c, and 30c. In relation to the sizes of the transmission gears secured on the respective transmission shafts, a transmission gear 30d of the shaft 30c having a large shaft size has a largest pitch circle size, and the pitch circle size is decreased in order of transmission gears 20d and 10d. Thus, during assembly, even when the output gears 10b, 20b, and 30b are inserted from an axial direction, they can be inserted without interference by the transmission gears 10d-30d, and the size of a housing 40 can be decreased as compared with engagement from a horizontal direction.

IPC: F02D11/10
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To improve follow-up stability of opening of a throttle valve in an electronic throttle system using a torque motor. SOLUTION: An electronic throttle system using a torque motor 19 can be simplified in structure with a small number of part items but has a tendency incapable of restraining overshoot of actual throttle opening TA as it cannot absorb friction enough as no gear proportional distribution of a reduction gear row exists in the midway. To cope with this tendency, corrective quantity to correspond with friction torque concerning a driving system of a throttle valve 5 is added at the time of computing demand torque of the torque motor 19. Consequently, an amount of friction torque caused by friction generated in the driving system of the throttle valve 5 is properly corrected and it comes to be possible to carry out precise throttle control, and it is possible to improve follow-up stability of the actual throttle opening TA to a target throttle opening.
