The battery accepting unit for a battery operated electric/electronic apparatus includes a plurality of positive terminals and a plurality of negative terminals. The battery accepting unit has a first position whereat a battery is connected by a pair of positive and negative terminals; a second position whereat a battery is connected by another pair of positive and negative terminals; a third position that can serve as both said first and said second positions; and a fourth position whereat a battery is connected by all positive and negative terminals. According to the battery accepting unit of the present invention, a battery pack can be exchanged without halting the power supply to an electric/electronic apparatus. Since an auxiliary power source, such as a sub-battery, is not required for an electric/electronic apparatus, a single power system, including a DC/DC converter and a charging circuit, can be provided. Therefore, the electric circuit in a system can be simplified, space can be saved inside a box, and manufacturing costs can be reduced.

To drive a liquid crystal panel without producing flickering or noise on a screen, an adder circuit 26 adds the noise component of the analog signal detected in a filter 24 to a reference voltage from a power supply 16, and a phase adjustment circuit 28 adjusts the phase of the reference voltage to which the noise component was added. A circuit 12 holds the analog signal and outputs it to comparators 14.sub.1 to 14.sub.n. The reference voltage from the circuit 28 is divided in resistors 18.sub.1 to 18.sub.n+1 and output to comparators 14.sub.1 to 14.sub.n as threshold voltages TV.sub.1 to TV.sub.n. The comparator 14 compares the input analog signal to the voltage TV, and outputs a predetermined signal to an encoder 20 if the analog signal is greater than the voltage TV. The encoder 20 converts the signal from the comparator 14 to a digital signal and applies it to the electrode of a liquid crystal panel.

In an interventional radiography (IVR), for example in a percutaneous transluminal coronary angioplasty (PTCA), when the IVR includes a period in which the movement of the object is slow, a normal X-ray radiating mode (a continuous X-ray radiation or a normal rate pulse radiation of about 15-30 pulses per second) is changed to a very slow rate pulse X-ray radiation of about 1-5 pulses per second to decrease the X-ray dose of the patient. Since the movement is slow, the very slow rate pulse radiation can still trace the movement adequately. Further, the quality of the X-ray image is improved by increasing the tube current in the very slow rate pulse radiation because less heat is generated in the X-ray tube.

A tracking method for reading/writing data with respect to an optical recording medium having clock tracks each formed of clock bits of optical patterns and data tracks. The method is carried out by irradiating from an optical lead side a pair of light beams onto a pair of clock tracks, with the beams so deviated from each other in a direction of relative movement of the optical head with respect to the medium that beam detection signals may have a difference in phase therebetween. Reflections of the respective light beams from the clock tracks are detected and a difference signal between reflections determined from the detection signals is obtained. A tracking-error signal from the difference signal is extracted and a zero-crossing point of the difference signal then is detected to extract a clock signal.

X-ray penetration images picked up by an X-ray penetrating device are supplied to an image processor, and stored in a magnetic disk unit as radiographic image data. The radiographic image data are reproduced on a reproduced image display monitor installed in an examination room. The examination room further includes a fluoroscopic image display monitor for selectively displaying the fluoroscopic images and menus. The menus include functions to select radiographic image data for reproduction on the reproduced image display monitor and to select a display mode. The functions shown on the menus may be selected and instructed by operating a joystick. During a procedure of interventional radiology, an operator operates the joystick to select and instruct desired radiographic image data to be reproduced. A display mode for enlarging reproduced images may be selected as necessary.

An electronic part such as a dielectric duplexer or filter is provided which comprises a dielectric ceramic block having a pair of opposite first and second side surfaces and an end surface meeting the first and second side surfaces nearly at right angles, an extension-electrode forming notch formed in the end surface so as to have an open end at the first side surface, a dummy electrode-forming notch formed in the end surface so as to have an open end at the second surface, the extension electrode-forming notch and the dummy electrode-forming notch corresponding in shape and position when observed in the direction in which the first and second side surfaces are opposed, an extension electrode formed in the extension electrode-forming notch, and a dummy electrode formed in the dummy electrode-forming notch. A method of forming an electrode of such an electronic part is also provided.

A magnetic head usable in a reader-writer for reading and writing data which can be magnetically processed. The magnetic head is characterized in that: it comprises a core (1), an exciting coil (2) for exciting the core (1), and a head case (3) for tightly enclosing the core (1) and the exciting coil (2); and a fuse is provided in a part of the exciting coil (2). When the reader-writer in which the magnetic head is incorporated is to be abandoned, the magnetic head can be easily destroyed, thereby enabling the prevention of fraudulent uses, such as the forging, of magnetic cards.
摘要:
An optical recording medium has a data storage section including data tracks and tracking lines formed in the data storage section for reading or writing data. The optical recording medium includes an elongated recording region defined between each two adjacent tracking lines, each of the data recording regions having at least one data track disposed offset from the center of the data recording region. The tracking method for the medium includes establishing a first optical detection region on the medium for detecting the tracking line position relative to the detection region and establishing a second optical detection region on the medium for reading or writing which is positioned in a fixed relationship to the first optical detection region. The first and second optical detection regions are positioned with respect to each other so that when the first optical detection region is tracking the tracking line, the second optical detection region is positioned for reading or writing along the data track at a position laterally offset from the center of the data recording region.
