Title: Fuel injection valve
Inventor: TAMAKI YOSHIYUKI
IPC: F02M61/18
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To improve atomization of fuel by making it easy to peel fuel at an inlet of a nozzle hole and promoting self-exited oscillation of a liquid column and a liquid film of fuel by connecting a seal part of a needle valve and a bottom surface on the lowest downstream side to each other through a specific intermediate surface forming a fuel channel inclined to the inside downstream. SOLUTION: Fuel flows in the F1 direction in a fuel channel formed and inclined between a downstream side part 13 of a valve body 1 and an intermediate surface 24 of the downstream side of a needle valve 2 after passing a clearance between each of seal parts 11, 21 of the valve body 1 and the needle valve 2 at the time of opening the needle valve 2. This intermediate surface 24 is formed so that a cross line (x) formed by crossing with a surface on the upstream side of a measuring member 3 comes to be on the outside of a circumscribed circle of an inlet opening part 41 of a nozzle hole 4.  Consequently, at the time when fuel is jet out from a nozzle hole 4 fuel is properly peeled at the time of flowing into the nozzle hole 4, a vortex grows in a flow of fuel immediately after an inlet of the nozzle hole 4, 5 liquid column and a liquid film of injection fuel are self-excited oscillated, and the fuel is properly atomized.

When the transmission of the vertical/horizontal signals 10 and 11 is stopped, the synchronizing detection circuit 1 supplies the image signal 12 and a switching horizontal synchronizing signal 14 which are in the same cycle as the signals 10 and 11 to the respective oscillation synchronizing circuits. At the same time, a screen flickering signal 16 is generated by an oscillation command signal 15 for the circuit 2. Thus, the fault of the image interface and the connected or disconnected state of the power source of a host system are recognized by flickering the image. Thus, the device rapidly complies with the fault and an operation mistake in the case of connecting or disconnecting the power source is avoided.

Abstract: PROBLEM TO BE SOLVED: To decrease stress that chips generate in glass and to prevent the unequal luminance of the glass by adopting such an array that the two segments connecting the centers of the joint surfaces of the two chips adjacent to each other do not exist on the same straight line for the array of the respective chips joined to the glass. SOLUTION: Such array that the two segments connecting the centers of the joint surfaces of the two chips adjacent to the chips do not exist on the same straight line is adopted for the array of the respective chips joined to the glass. Namely, the elongated chips 1a, 1b are arranged on the neighborhood of the two sides on the circumference the glass 2 in such a manner that their positions are offset from the adjacent chips. A polarizing plate 4a and the glass 3 are adhered to both surfaces of the glass 2. The stresses of the glass assume a distribution that the stresses increase at the ends of the chips but the ends of the adjacent chips 1a, 1b stagger and, therefore, the occurrence of the superposition of the stresses generated by both chips 1a, 1b is averted and the occurrence of the unequal luminance in the glass 2 is prevented.

Filed: 1985-08-29
Abstract: PURPOSE:To read special characters by decoding again characters having a decoding error in a decoding process of standard characters in a decoding process of special characters. CONSTITUTION:Bar codes are operated by a reader 7 to store values corresponding to respective areas consisting of bars and spaces in a data storing circuit 4. Then respective characters are decoded in a standard character decoding process according to the value stored in each area. The character having a decoding error in the standard character decoding process is decoded again in the special character decoding process. In such a way, not only the standard character but also the special characters can also be read completely. This omits a process to decide whether the characters to be decoded are equal to standard or special characters.
