Title: Distributing type fuel injection pump
Inventor: NAKAMURA HISASHI
IPC: F02D1/18
Filed: 1989-08-02
Abstract: PURPOSE:To improve responsibility by communicating the high pressure group of a timing control valve with the upstream side of a timer piston high pressure chamber, and directly connecting the high pressure group and a pump room through a fixed orifice. CONSTITUTION:The flow of fuel oil in a pump room 9 is throttled down with a fixed orifice 34 of a pump housing 1, flows into the high pressure group 30 of a timing control valve 3 through a passage 35, then into the high pressure chamber 20 of a timer 2 through a passage 33. If electricity is turned on to the solenoid part 3c of the timing control valve, a needle valve 3a is opened to communicate the high pressure group 30 and a low pressure hole 31, and the pressure from the high pressure chamber 20 of the timer 2 is leaked into the low pressure chamber 21 through a passage 35, the low pressure hole 31 and a low pressure passage, which determines the position of a timer piston 2b in balance with a spring 21 to change the timing. The responsibility of the timer piston is thus improved to raise injection timing control performance.

Title: Method for opening package
Inventor: KOBAYASHI KOJI
IPC: B65B69/00
Filed: 1987-08-10
Abstract: PURPOSE:To increase the speed of opening work, by preliminarily allowing a bifurcated pawl body to fall so that the leading end of the insert part formed to the end part of the bifurcated pawl body is positioned between the upper end of a package and the bundling member of the uppermost stage before the package is pressed to a definite position. CONSTITUTION:When a package 2 is placed at the opening position of a mount apparatus 3, a push apparatus 14 presses the package 2 to laterally move the same until the package is brought into contact with a holding apparatus 18. Before this press process, a bifurcated pawl body 10 is preliminarily allowed to fall so that the insert part 10A formed to the end part of the bifurcated pawl body 10 is positioned between the upper end of the package and the bundling member 4a of the uppermost stage. In this state, the bifurcated pawl body 10 largely falls to be inserted in the bundling member 4 binding the package 2. By this method, the bundling member such as the wire used in the bundling of the package is automatically taken up by simple operation due to the insertion and rotation of the bifurcated pawl body to increase the speed of opening work. At this time, it is prevented that the package is thrust or a paper piece is torn by the falling of the bifurcated pawl body and the scattering of paper waste is prevented.

Title: Interferometer using optical fiber ring
Inventor: SONOBE HISAO
IPC: G01C19/00
Filed: 1984-09-26
Abstract: PURPOSE:To obtain clear interference fringes, by inputting converging luminous flux through a beam splitter into an optical fiber loop under the good conditions, and differentiating the starting points of diverging luminous flux outputted from the optical fiber loop at the same time. CONSTITUTION:A beam splitter 3' and a semitransparent mirror 3R' are exclusively used either for P polarization or S polarization. For example, when laser light is linearly polarized light and the direction of polarization is in parallel with the surface of paper, the product is exclusively used for the P polarization. When the direction is perpendicular to the surface of the paper, the product is exclusively used for the S polarization. Interference fringes 7B are obtained by limiting the unnecessary luminous flux. The fringes have the fringe pattern of concentric circles because two starting points are located on the same lines and the diverging luminous fluxes, whose distances from an interference plane 7 are different, are interfered. The interference fringes 7B show a clear fringe pattern, because the luminous fluxes, which are outputted from end surfaces A and B of an optical fiber loop 6 and reach the interference plane 7, are larger than the luminous fluxes, which are reflected by the same end surfaces and reach the interference plane 7.

Abstract: PURPOSE:To provide an optical receiver which is simple in circuit structure and capable of amplifying a photocurrent well without distorting it. CONSTITUTION:A first photodetector 2 and a second photodetector 3 both generating a photocurrent are provided in an optical receiver, a second photocurrent i2 outputted from the second photodetector 3 is compared with a reference current iS through a current comparison amplifier, and when it is found that the second photocurrent i2 is smaller than the reference current iS, an output current is set to zero, and when the second photocurrent i2 is larger than the reference current iS, the second photocurrent i2 is amplified as much as a current gain K and then outputted. In a differential amplifier 6, a difference between a first photocurrent i1 outputted from the first photodetector 2 and an output current from the current comparison amplifier is amplified and outputted. Therefore, when a photocurrent is small, only the first photocurrent is amplified, and when a photocurrent becomes large, a difference between two photocurrents is amplified, so that an excessive current large enough to make a differential amplifier saturated is prevented from flowing into it.
