Title: Method of measuring neutron multiplication constant of internal distribution system of neutron source
Inventor: UEDA KIYOSHI
IPC: G21C17/06
Filed: 1988-03-31
Abstract: PURPOSE:To detect neutrons and to easily monitor the criticality safety in respective stages by merely disposing plural neutron detectors dispersedly to the outside circumferential part or internal part of multiplying system without requiring an external neutron source. CONSTITUTION:The neutron fluxes at respective points (a)-(d) attain a COS or SIN distribution in case of the critical system if the points (a)-(d) are considered on the axial center with the neutron multiplying system 1. The neutrons born at the point (d) are annihilated in the next generation or the generation after the next generation when the subcritical degree is deep and, therefore, the gamma rays thereof can be seen only within, for example, the circle shown by a dotted line enclosing the point (d). The same holds true of the points (b), (c). While the same holds true of the point (a), there is one difference in that the number of the neutrons contributing to the multiplication to the next generation decreases within the system if the descendants leak partly to the left side of the system and, therefore, the neutrons viewed normally decrease. The neutron flux distribution shown by the curve (p) is resulted if the subcritical degree is extremely deep. The circle shown by the broken line grows larger and the probability of the leakage of the neutrons generated at the point (a) to the outside of the system increases as well when the subcritical degree is shallower. The neutron flux distribution shown by the curve (q) is similarly obtd. as well at the point (b).

IPC: H01L21/302
Filed: 1978-07-03
Abstract: PURPOSE: To maintain long-period reliability of a light-receiving element by covering it with an insulating film immediately after formation of groove shape by charging particles surrounding the element.  
     CONSTITUTION: Ar and O are introduced into a chamber 15 having a pressure of approximately 10 -6  torr, discharging is started by biassing electrodes 7 and 12 conversely, and ions are allowed to impinge against surrounding section of an element of a base plate 11 through a mask so that a groove is formed. The mask 10 is removed after completion of the groove formation, and the electrodes 7 and 12 are continuously biassed to allow the ions to impinge against Si target 8 so that SiO 2  is adhered onto the base plate 11. At this time, if SiO 2  is provided into an appropriate thickness, it becomes able to be utilized for a reflection-preventing film. It is possible, in this way, to form a segregating or separating film easily and also to obtain a long-period reliable protective film of good element characteristics.

Title: Control circuit of positioning device
Inventor: ABE RIICHI
IPC: G05D3/12
Filed: 1989-03-30
Abstract: PURPOSE:To eliminate the delay of response to a stepwise command input without affecting steady operation and to improve response characteristics by supplying an initial value to an integrating function that a servo amplifier has when the control circuit of the positioning device commands a target position. CONSTITUTION:When a command signal 7a is generated stepwise, the deviation signal between the speed command signal 7a and a detection signal 7b is inputted to an operational amplifier 1. Simultaneously with the input of an input command signal to the operational amplifier 1, a switch 4 is switched to the (b) side and the voltage of a capacitor 5 which is charged with a DC voltage 3 is inputted to the plus input terminal of the operational amplifier 1. The terminal voltage across the capacitor 5 is discharged by a resistor 6, but the capacitor is charged with a voltage with a polarity in such a direction that the deviation signal between the command signal 7a and feedback signal 7b is applied to the operational amplifier 1, so delay characteristics are corrected. Thus, when the target position is commanded, the initial value is supplied to the integrating function that the servo amplifier 1 has. Consequently, the control circuit with good response can be realized.

Title: Signal processing circuit of solid state image pickup device
Inventor: HAMADA AKIHIKO
IPC: H04N5/335
Filed: 1981-05-27
Abstract: PURPOSE:To eliminate the noise contained in the signal with high accuracy without having a complicated constitution, by giving the differential waveform shaping to the output of a solid state image pickup device (CCD) and then detecting and holding the peak of the output signal. CONSTITUTION:A clearing switch 21 is temporarily turned on, and the potential is set VG at a point (c). The output signal supplied from a CCD (not shown in the diagram) receives the differential shaping with a time constant formed by a capacitor C10 and a resistance R10 and then receives a conversion of impedance through an amplifier 20 to be applied to a diode D1. For the output of the amplifier 20, only the voltage in the direction allowed to the polarity of the diode D1, and the peak level of the signal is held by a capacitor C11. The switch 21 is turned on again before the differential wave of a reset waveform, i.e., the transient switching noise of the CCD signal is supplied. Thus the noise contained in the signal is eliminated. A diode D2 prevents the transient voltage to the signal in the direction where the differential waveform is not required.
