Title: Frequency divider circuit
Inventor: MORI YASUSHI
IPC: H01P9/00
Filed: 1994-07-12
Abstract: PURPOSE:To attain a secure frequency division operation by forming a delay circuit with a microstrip line on a printed circuit board and adjusting a transmission delay time by the length of the line. CONSTITUTION:A latch circuit 2-0 uses a D flip-flop circuit and receives a serial clock signal from a serial clock signal input terminal 1-0, latches the signal in the rising edge timing and a parallel clock signal is outputted from an output from an output signal terminal 4-0. A delay circuit 3-0 is formed by a microstrip line and delays an inverted output signal of the latch circuit 2-0 from the terminal 4-0 by a prescribed time and provides an output to a D input of the latch circuit 2-0. Then the transmission delay time is set by adjusting the length of the microstrip line. Thus, even when the transmission delay time of the delay circuit 3-0 is longer than a period of the clock signal, if the time is shorter than the period after frequency division, the delay time is set to be operated with high accuracy.

Title: Pulse width control switching power supply
Inventor: TERAJIMA HIDEO
IPC: H02M1/00
Filed: 1995-06-27
Abstract: PURPOSE: To protect a switching transistor against damage owing to abrupt spreading of pulse width caused by short circuit of load at the time of varying the maximum pulse width set point (dead time) of drive pulse. CONSTITUTION: A pulse width detection circuit 3 detects the width of drive pulse and applies a detection voltage to the dead time control input B of a control circuit 2. When the voltage of an input power supply 4 increases to limit the width of drive pulse in the control operation, the detection voltage is increased correspondingly and the dead time of a control circuit 2 is limited. Since the maximum width of drive pulse is limited by the dead time even upon occurrence of trouble by short circuit of load, for example, a switching FET 11 is protected against damage.

Title: X-ray image intensifier
Inventor: KIMURA YUUTAROU
IPC: H01J31/50
Filed: 1983-08-31
Abstract: PURPOSE:To enable both of a highX-ray quantum detection efficiency and a high resolution to be attained at the same time by installing a window for incident X- rays in such a manner as to locate it facing the photoelectron-discharging screen through a part of an encircling case placed sufficiently apart from said screen. CONSTITUTION:A window 12' for incident light is provided in an area (A) which face a photoelectric screen 18' through a part of an encircling case 10' directly facing the screen 18' so that X-rays become incident upon the photoelectric screen 18' in contrast with the conventional X-ray image intensifier. Light emitted from a CsI layer 16' installed on the side of the surface for incident X-rays, because of the short distance between the layer 16' and the photoelectric screen 18', stimulates the photoelectric screen 18' to a great extent and is spred only in a small degree by optical scattering. Such an effect is specially effective since a large quantity of emission is produced near the surface for incident X-rays or near the photoelectric screen 18'. Consequently, a high luminance and a high resolution can be attained at the same time.
