    摘要: An image-forming apparatus for exposing a photosensitive material with image light. An optical modulation device is provided such that the intensity of image light made incident from one side of an optical modulator is modulated in correspondence with the intensity of the image light made incident from the other side of the optical modulator as well as a drive voltage to be applied, and the image light made incident from one side is made emergent from the optical modulator. Since the modulation of the intensity of the image light is effected by the optical modulator, the amount of exposure supplied to a printing paper is controlled in correspondence with the density distribution of the image on a negative film, and an image having appropriate contrast can be reproduced by effective use of the latitude of the printing paper.

    摘要: In a memory circuit having a memory device operative to read, write and hold data and an operation unit implementing computation between a first datum supplied externally and a second datum read out of the memory device, a selector for selecting one of operational function specification data preset externally and a selector for selecting one of bit write control data present externally are given with select control signals, so that a frame buffer memory operative in read-modify-write mode can be used commonly.

    摘要: A protective tube is vertically buried in the ground, and sinking elements for generating magnetism are buried at plural positions at different depths in the ground outside the side wall of this tube. Magnetic sensors capable of detecting magnetism are disposed in the tube to detect the magnetism generated by the sinking elements, and the depth position of the sinking elements in the ground is measured according to the detected signal, so that the fluctuations by settlement or uplift of the ground may be known by each bed differing in depth. A plurality of magnetic sensors are fixed to the side wall surface of the tube, corresponding to the individual sinking elements.

    摘要: A field control apparatus for a generator having a field winding comprises a terminal voltage control unit for controlling a field current of the generator in accordance with a difference between a terminal voltage signal of the generator and a reference voltage signal, which control unit has at least one of a line drop compensation function, an under-excitation limitation function, an over-excitation limitation function, a power factor regulation function, an armature winding over-current compensation function and a cross-current compensation function. The field control apparatus includes a detector as a common signal source for detecting active power and reactive power components at an output terminal of the generator and means responsive to the output of the detector for performing scalar operation in accordance with a function of the added compensation/control function described above. An output of the operating means is added to the differential signal as an added function signal to control the field current for excitation of the field winding.
