Abstract: PURPOSE:To always measure an accurate degree of color developing toner color mixture by estimating the spectral density of an object to be measured, namely, an image formed by color developing toner and estimating the color developing toner chromaticity in accordance with the spectral density. CONSTITUTION:A reference image forming part 101 is provided in the non-image forming part of an image carrier 8 and is constituted by laminating a conductive body and a white photosensitive body, and a reference image is formed with color developing toner by electrification, exposure, and development processes. A spectral density detecting means 102 detects the spectral density of the reference image formed in the reference image forming part 101. A reference image removing means 103 removes color developing toner particles forming the reference image from the reference image forming part 101, and the reference image forming part 101 is returned to the same white as the initial state. That is, the spectral density of the reference image formed by color developing toner as the object to the measured whose degree of color mixture should be measured is measured, and the degree of color developing toner color mixture is estimated in accordance with the spectral density. Thus, the accurate color developing toner color mixture is always measured.

Title: Solenoid operated fuel injection valve
Inventor: TAKEDA HIDETO
IPC: F02M51/08
Filed: 1985-11-26
Abstract: PURPOSE:To obtain stability of atomization in every time, by providing a guide member in a stay connected with a valve unit and slidably moving the guide member along the peripheral surface of a fixed iron core so that a movable iron core can be prevented from tilting. CONSTITUTION:When a valve is assembled, parallelness of a movable iron core 15 with a spacer 9 is not maintained, but the movable iron core 15, if it is once attracted to the side of a fixed iron core 4, collides against the spacer 9 stopping in a valve opening position. Here the movable iron core 15 is placed in a closely attached condition (parallel) with the spacer 9 because moment by impact force is set larger than the moment by friction. While a guide member 41, provided in a stay 16c mounted to the upper part of a valve unit 16, moves sliding on the internal peripheral surface of a center axis cavity part of the fixed iron core 4, and the injection valve, in which the valve unit 16 can be slided in the axial direction with no change of rotation, maintains the parallelness by friction force acting between the movable iron core 15 and the valve unit 16. Accordingly, the movable iron core 15 is placed always in parallel with the fixed iron core 4.

Title: Automatic adjusting controller for power factor
Inventor: YAMAZAKI KIYOKUMA
IPC: G05F1/70
Filed: 1987-10-21
Abstract: PURPOSE:To extend a control area by changing the interrupting level of a capacitor to zero Var when the interrupting level is at the delaying area of a phase, namely, the area of the power factor adjustment is at the area of the delaying invalid electric power. CONSTITUTION:An interrupting discriminating means discriminates whether or not an invalid electric power ordinarily exceeds the interrupting level of a capacitor, namely, whether or not the power factor slips off from an adjusting area in the direction of the phase-lead. In a phase discriminating means, when the interrupting level is judged to be at the phase-lag area, it is discriminated whether or not the invalid electric power exceeds zero Var, namely, whether or not the power factor slips off from the extended adjusting area in the direction of the phase-lead. In an input discriminating means, an input means inputs a capacitor to an electric circuit in the prescribed control sequence, for example, in the sequence of a larger capacity when the invalid electric power lowers the input level. Thus, in the interruption discriminating means, the interrupting means interrupts the capacitor from the electric circuit in the prescribed control sequence, for example, in the sequence of a smaller capacity when the invalid electric power exceeds the interrupting level or the zero Var.
