Title: Method of measuring shape of screw
Inventor: KOZONO HARUO
IPC: G01B21/20
Filed: 1979-02-26
Abstract: PURPOSE: To accurately and quantitatively determine a screw shape such as a periodically appearing wrong form, by measuring the shape of a screw along a screw groove over the total circumference and entering tridimensional dot row coordinate values into a computer to perform calculation.  
     CONSTITUTION: A tridimensional digital shape detector is used to measure the shape of a tested screw 3. A head on the tip of a measuring member is caused to trace the groove of the screw over the total circumference of the groove to enter tridimensional dot row coordinate values at each minute pitch into a computer 7. In the computer, the stored coordinate values are processed by the method of least squares so that geometrical characteristic values such as the eccentricity from a supposed center and the lead and taper of the screw are determined and indicated on a graphic display 9 and a plotter 10.

Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To decide the effective bright time output with high accuracy by outputting the bright time output voltage, as well as the reference voltage which secures a potential equivalent to the dark time output voltage that is set, when a photodiode is initialized to each light-receiving element at all times in its working mode. SOLUTION: A reference voltage VREF1, i.e., the initial potential of a photodiode is applied to the source of a 2nd electrode of a MOS transistor TR 2 which functions to reset the photodiode in its initial state. The output of an amplifier 3 is supplied to a common signal line 15 via a MOS TR 4 which serves as a read switch. The line 15 is connected to an image sensor signal output terminal SIG which outputs an image sensor output signal VSIG via a MOS TR 6, that serves as a chip selection switch with which the output of an amplifier 5 selectively actuates the function of a 2nd amplifier. Thus, a photodiode is used as a light-receiving element, and the potential of the 2nd electrode which varies according to the received light quantity is read outside via an amplifier.

Abstract: PURPOSE:To enable a continuous picture to be seen on a large picture screen from a  relatively short distance by displaying a number of picture elements on the luminous  screen of a light source, providing light guides correspondingly to the picture elements,  and densely arranging the ends of the light guides so that they are adjacent to each  other. CONSTITUTION:A cathode-ray tube 11 has an electron gun 3 which produces one or  plural electron beams, as well as an electromagnetic deflection york 4 or an electrostatic deflecting part which deflects the electron beams. A specific number of picture  elements 66 are displayed on the fluorescent screen of the cathode-ray tube 11. Light guides 221, 222, 223..., which correspond to the picture elements 66, introduce luminous  light sent from the picture elements 66 onto a display board. The side walls of the light  guides 22 are densely arranged so that they extend from the input window side to the output window side adjacently to each other. The area of the input window is larger  than that of the picture element 66. In addition, in order to remove the influences of  both the interval of the arrangement of picture tubes and the thickness of the panel- glass end part of the picture tubes on the output side, and to densely arrange the output windows of the light guides 22, it is inevitably necessary to make the area of the  output window of the light guide 22 larger than the area of its input window.

When no control signal is given, switching elements 9H, 9L are both turned off and a control voltage signal generator 10 transmits a voltage signal of 20V to the control receiver 2 side via core wires 3A, 3B. When the low temperature control signal S(L) is outputted, the switching element 9L is turned on, a current flows to a resistor 8L, and a voltage signal of 15V is transmitted to a core wire 3. Moreover, when the S(H) and S(L) signals are outputted, the switching elements are both turned on and a voltage signal of 10V is transmitted to the core wire 3.

Abstract: PURPOSE:To attain fully decrement of dissolved oxygen and to prevent rising of radiation dose rate of a turbine system by injecting a hydrogen. CONSTITUTION:By arranging a material 22 having fairly large (n, gamma) reaction cross-section at an inside or outside of the outermost circumferential shroud of a BWR reactor core 1 and by changing neutron at a BWR downcomer part 5 into gamma ray, oxygen/hydrogen recombining reaction at the downcomer part, is well accelerated. Otherwise, by providing an irradiation measures 23 of electromagnetic wave such as light beam (the most appropriate wave length is less than 400nm), decomposition of hydrogen peroxide is also accelerated. With this constitution, even when hydrogen injection amount is reduced to a BWR primary cooling system, to the extent that gaseous phase transfer of radioactive nitrogen which causes rising of radiation dose rate, is not induced, the hydrogen injection is enough effective for reduction of dissolved oxygen.

Title: Device for detecting gap voltage of wire cut
Inventor: OBARA HARUKI
IPC: B23H7/02
Filed: 1988-02-03
Abstract: PURPOSE:To obtain a more accurate gap voltage by providing voltage detecting means for detecting each voltage between an upper electrifying piece and a workpiece and between a lower electrifying piece and the workpiece, adding the outputs of the two voltage detecting means by a computing means, and obtaining the gap voltage from the added value. CONSTITUTION:By feeding electricity from a machining power source 1 via upper and lower electrifying pieces 4, 5, as a voltage is applied between a wire 2 and a workpiece 3 to start discharge, the voltage is divided into the voltage between the upper electrifying piece 4 and the workpiece 3 and the voltage between the lower electrifying piece 5 and the workpiece 3, which are inputted into a computing element 11 and added. In this case, since the values of the inductances L1, L2 of a discharge circuit are normally larger than those of the inductances l1, l2 between upper and lower electrifying pieces 4, 5, the output VG of the computing element 11 becomes the added value of the divided values due to the effect of the inductances L1, L1 of the discharge circuit. This added value is not affected by the change of a discharging position P and, since a gap voltage Vg is obtained from this added value, a more accurate gap voltage Vg can be obtained.
