Patent JP-S59104815-A (JP)
Title: Interface circuit
Inventor: NAGAI YASUO
IPC: H03K19/018
Filed: 1982-12-08
Abstract: PURPOSE:To attain the signal transmission to plural signal transmitting paths without decreasing the amplification degree of an amplifier output signal by prodiving a transistor(TR) operated to ON state or OFF state. CONSTITUTION:The input impedance of a TRQ11 viewed from an output terminal Tout becomes a comparatively high value by providing the TRQ11 to an interface circuit 2. Thus, almost no current flows from a collector of a TRQ6 of an amplifier circuit 1 to the interface circuit 12. Then, it is not required especially to use TRs having a large power capacity for TRs Q6, Q8 constituting an output circuit, nor an output voltage Vout is attenuated. Thus, the signal transmission to plural signal transmitting paths is attained.

Title: Semiconductor read only memory
Inventor: HARA HIDEO
IPC: G11C17/00
Filed: 1983-11-16
Abstract: PURPOSE:To speed up an access time by dividing MOSFETs requiring series connection into plural groups and synthesizing the output signals from the plural groups afterward. CONSTITUTION:When an input signal of m=n=12 is given, terminals A11-A1n, e.g., are used for decoders for addresses 0-2047 and A21-A2m are used for decoder for addresses 2048-4095 by controlling pairs between one of the A11- A1n and A21-A2m. The combined resistance of the m+n-set of MOSFETs is divided into m:n in this way to reduce the combined resistance of the MOSFETs between output terminals O1, O2 and ground. Thus, the time constant of each time constant circuit comprising a source-drain resistance of the MOSFETs connected in series in ROMs 2, 3 and capacitors C1, C2 is nearly a half in comparison with the case that the m+n-set of the FETs are not divided at all.

IPC: G01N23/04
Filed: 1998-07-14
Abstract: PROBLEM TO BE SOLVED: To image good radiographs by detecting information about the relative localizations of a radiation source and a cassette, and performing always accurate alignment. SOLUTION: An engineer secures a cassette 11 to the shoulder joint of a patient in accordance with Johner's position imaging method. The engineer then displaces a radiation source 10 and starts alignment so that radiation is emitted perpendicular to the cassette 11 and toward the centerline of the cassette 11. Then a liquid crystal display means 13 provided on the radiation source 10 displays the relative positions of the radiation source 10 and the cassette 11, i.e., the state of alignment in real time. The engineer can easily achieve accurate alignment by checking the display of the state of alignment. The liquid-crystal display means 13 can display not only the relative positions but also the attitudes of the radiation source 10 and the cassette 11.  Therefore, an operator can rapidly deal with the displacement of the already installed cassette 11 due to the movement of the patient, etc.
