Title: High speed switching circuit
Inventor: FUJIMAKI SHIGEO
IPC: H03K17/04
Filed: 1988-09-09
Abstract: PURPOSE:To make a turn-on time of a transistor(TR) equal to a turn-off time by adopting the constitution such that the time constant of the circuit varies with an input square wave potential. CONSTITUTION:The time constant of an equivalent circuit for base-emitter connection of a TR 50 is expressed as Cbe.Rbe, where Rbe is a resistance of a resistor 51 and Cbe is a capacitance of a capacitor 52. Moreover, the time constant of a parallel circuit comprising a resistor 10, a varactor diode 20 and a variable capacitor 30 is expressed as (Cd+Cv)RB, where RB is the resistance of the resistor 10, Cd is the capacitance of the varactor diode 20 and Cv is the capacitance of the variable capacitor 30. Then the value Cv is decided so that the time constant (Cd+Cv)RB is made coincident with the time constant Cbe.Rbe in matching with the change in the potential of the input square wave. Thus, the turn-on time of the TR 50 is made equal to the turn-off time.

Title: Resin for photoformation method
Inventor: MURAKAMI TAMOTSU
IPC: C08F2/54
Filed: 1999-08-09
Abstract: PROBLEM TO BE SOLVED: To provide a resin which is used for photoformation methods and enables the formation of three-dimensional formed products having high surface accuracy by simple means. SOLUTION: This resin for photoformation methods contains an X-ray curable component which can sensitively be cured by the irradiation of X-rays having a stronger substance-penetrating force than that of UV light. Since the resin composition can be photocured using the X-rays, operation labors can be reduced, when a three-dimensional formed product having a large width in the depth direction is formed. Since the joined portions of cured resin layers can further be decreased, the unevenness of the surfaces of the formed product can be reduced.

Title: Reading method for x-ray film picture
Inventor: NONAKA MASAAKI
IPC: G03B27/72
Filed: 1985-10-11
Abstract: PURPOSE:To prevent the reduction of the information quantity with a small-size film by dividing the size of the reading picture element of the film pictures of different sizes into the picture element sizes which divide the film picture almost equally into a prescribed number of picture elements. CONSTITUTION:The current signal obtained from a photoelectric converter 20 is amplified 21 and converted into the voltage signal. This voltage signal is sampled/held 22 and stored in a buffer memory of a computer 24 after A/D conversion 23. Here a timing control part 25 detects the film size to supply a prescribed sample clock to a sampling/holding circuit 22. Thus the picture data stored in the buffer memory is transferred to the computer 24. Furthermore the part 25 gives the number of pulses decided by the film size to a pulse driver part 27 and therefore the secondary scan is possible by an amount equal to the picture element size decided by the film size. Such a procedure is repeated over the number of lines decided by the film size.
