Title: X-ray photographic apparatus
Inventor: FUJII HIDEKI
IPC: H04N5/321
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To easily set an appropriate X-ray photographing condition with suppressed exposure dosage by providing an intermediate position photographing condition setting means for finding and setting an X-ray photographing condition of an intermediate photographing position based on the X-ray photographing condition of each photographing position at both ends and the intermediate photographing position. SOLUTION: At first a CPU 18 calculates an intermediate photographing position based on both ends photographing positions and the size of the I.I tube (Image intensifier). At that time, the positions are divided so that deficient photographing would not occur between adjoining photographing positions, and the detecting planes of the I.I tube 2 overlap with constant width between photographing positions. The calculated intermediate photographing positions are sent to a photographing position memory 9 and recorded. Also, the CPU 18 calculates the voltage value for tube voltage of each intermediate photographing position using the tube voltage of the photographing positions at both ends, and each voltage obtained for each intermediate position is memorized in an X-ray photographing condition memory 23 as the X-ray photographing condition of the intermediate photographing position.

Filed: 1989-06-28
Abstract: PURPOSE:To perform an operating frequency test at a tester limit speed or more by mounting an exclusive logical circuit receiving two clock pulses mutually shifted in phase by a 1/4 period as an input signal and using the output signal thereof as a clock to perform operation. CONSTITUTION:An exclusive OR gate 3 and a delay means 4 are connected to the input buffer 2 connected to a clock input terminal 1. An AND gate 7 controlled by the test mode control signal inputted through a terminal 5 and an input buffer 6 is connected and the output signal thereof is supplied to the gate 3. The means 4 determines the sum of said output signal and the delay time of the gate 7 so as to set the same to the 1/4 period of an input clock. When the clock is supplied to the terminal 1 and the test mode control signal of the terminal 5 is changed to a high level, the clock is delayed by the means 4 to be supplied to the gate 7 and the output signal thereof is also delayed by about a 1/4 period to be changed and the output signal of the gate 2 becomes a pulse of a period 1/2 that of the clock. By this method, test operation can be performed at frequency twice the input clock of an LSI.

Abstract: PURPOSE:To improve short time frequency stability of a gas cell type Rb atomic oscillator, by removing harmful components in the light emitted from a lamp cell, decreasing the output of a solar battery, and increasing the S/N of an atomic resonation signal. CONSTITUTION:Most of the harmful optical components, whose spectral intensity is large, is present in the visual light region. Therefore an optical glass filter 13 is employed and inserted between a lamp cell 1 and a resonating cell 5 or between the cell 5 and a solar battery 7. Or it is used as the window of a lamp house. In the lamp cell 1, Ar or the like is included in addition to Rb<87> for accelerating discharge.

All other wavelength components are harmful components which are to become noises for the output of the solar battery. In this constitution, only the insertion of the simple glass filter can effectively remove the harmful light, the output frequency of a voltage controlled crystal oscillator 10 is controlled with a stable resonant frequency of the Rb<87> as a reference, and high degree of stability is obtained.

Abstract: PURPOSE:To set a voltage used in an internal circuit at an arbitrary value while an input/output signal level is maintained at a TTL level and to improve reliability by bringing the level of the signal into coincidence with an external signal level. CONSTITUTION:In an input signal level converting circuit 31 in an input signal level converter 3, if an external input signal has an H level (TTL level, 5 volts), a PMOS transistor 314 and an NMOS transistor 315 are turned ON to convert 5 volts to 3 volts (H level of internal signal level) and to output it. On the other hand, in an output signal level converting circuit 41 in an output signal level converter 4, if an internal output signal has an H level, a PMOS transistor 414 and an NMOS transistor 415 are turned ON to convert 3 volts into 5 volts (H level of TTL level) and to output it. That is, since the signal having only the internal signal level is input or output through the converters 3 and 4, a voltage can be stepped down to 3/5 in an internal circuit 2.
