Title: Control device for charging raw material
Inventor: IRIE HIROYUKI
IPC: B65G43/00
Filed: 1991-04-01
Abstract: PURPOSE:To provide a raw material charging control device for preventing different types of materials from being erroneously charged in a raw material charging facility for feeding proper materials or ores as auxiliary materials whenever necessary to a blast furnace, sintering furnace, converter or the like. CONSTITUTION:When a discharge confirmation key 18a is first pressed, the indicator lamp 18b thereof lights. Then, when one vessel is selected among a plurality of charging stock pile vessels by pressing a key 16a, the indicator lamp 16b thereof lights and the indicator lamp 15b of a takeout vessel registered in a memory 23 starts to flicker, corresponding to the lighting of the indicator lamp 16b. When a key 15a corresponding to the lamp 15b is pressed and the takeout vessel is selected, the flickering changes to continuous lighting. Therefore, when an automatic start key 17 is pressed and the key 18a is again pressed, indicator lamps are turned off, starting from the lamp 18b, thereby allowing the start of control operation. If other keys are pressed to select another stock pile vessel, however, the selection is invalidated and the operation is prohibited.

Title: Apparatus for measuring potential difference
Inventor: ICHIJO HIROSHI
IPC: G01R19/25
Filed: 1986-04-24
Abstract: PURPOSE:To measure the peak-to-peak potential within an arbitrary measuring section, by operating the potential difference between the max. and min. voltages within a measuring section from the difference between respective digital data when the reversal and non-reversal of the output of an analogue comparator are detected. CONSTITUTION:A data supply means outputs digital data to a D/A converter 6 to convert the same to an analogue signal which is, in turn, compared with a signal to be measured by an analogue comparator 1 and a gate means 2 permits the output of the comparator 1 to pass only during a measuring section signal applying period. A reversal section means 3 detects that the output of the comparator 1 passing through the means reverses. A control operation means 4 respectively reads first output digital data at the time when the reversal of the means 3 is detected and second output digital data at the time when the non-reversal of the means 3 is detected from the data supply means to operate the potential difference between the max. and min. voltages within a measuring section on the basis of the difference between both digital data. By this simple constitution, the peak-to-peak potential within the arbitrary measuring section of the wave form on the surface of an oscilloscope tube can be measured.

Title: Method of measuring minute angle
Inventor: NAKAYAMA KAN
IPC: G01B11/26
Filed: 1979-07-25
Abstract: PURPOSE: To easily measure an angle in a wide range with sensitivity more accurate than 0.1", by detecting the change in the phase of light caused by the rotation of a reflector.  
     CONSTITUTION: Light flux emitted from a light source 1 is converted into parallel rays of light with an appropriate diameter by a collimator 2. The parallel rays of light are entered into a diffraction grating 4 so that the rays of light proceed in several different directions while keeping a coherent phase relationship. Since the grating 4 is located on the focal plane of a lens 5, the rays of light are transmitted through the lens and proceed in such a direction that the rays are condensed to the focal plane of the lens and reflected by a reflector 6. Only the first-order and the zero-order diffracted rays of light among those divided by the grating 4 are picked out through slits 9 and reflected by the reflector 6 and returned to the grating 4 so that the returned rays of light are diffracted again. Both the rediffracted rays of light proceed in the same direction and interfere with each other. The phase relationship between each pair of two rays of light changes depending on the rotation of the reflector 6. The change in the phase relationship is detected to measure a displacement of minute angle.
