Abstract: A USB device for performing communications with a second device through a USB interface while supplying electric power to the second device through a power-source supplying line in the USB interface. The USB device includes a communication unit for communicating with the second device, a power source capable of outputting electric power of a voltage being different from a standard power voltage prescribed in the standards of the USB interface. The power source supplies the electric power to the second device through the power-source supplying line. The second device includes a low load unit and a high load unit The power source supplies the electric power having a power voltage higher than the standard power voltage to the high load unit through the power-source supplying line.

Abstract: In a CPU, a FET is turned off and power is not supplied to a power supply element of a transceiver for a period of time until predetermined initialization processing, which is implemented in a peripheral device when power is supplied via a cable from a host PC, has been concluded (i.e., a period of time until it becomes possible for the peripheral device to initiate data communication with the host PC). Thus, even if the peripheral device and the host PC are physically connected by a cable, data signals transmitted along signal lines are not relayed by the transceiver to a logic controller, whereby it in effect becomes possible to set the peripheral device in a pseudo-non-connected state with respect to the host PC.

Abstract: While a general-purpose interface circuit and another general-purpose interface circuit are provided so as to transmit/receive data between a host appliance and a device appliance, when the general-purpose interface of the device appliance happens to hang up, a control section transmits a reset signal via a dedicated interface circuit. When a dedicated interface circuit provided on the side of the device appliance receives this reset signal and then outputs this received reset signal to the general-purpose interface circuit, the general-purpose interface circuit is reinitiated.

Abstract: An easily recognized spatial relationship between an object and a section thereof is displayed (together with a real time image of the section) to permit quick, accurate, easy and accurate selection of a desired three-dimensional position for the section. The coordinate system of an imaging system may also be concurrently displayed. In addition to sequentially pasted real time section images, a reference image acquired at an arbitrary time may also be pasted on a portion of the display. Thus a reference image and a real-time image of the scanned section can be displayed to facilitate a better spatial understanding of the position of the section being scanned and imaged.

Abstract: An electronic equipment mounting angle varying apparatus comprises a base member mounted at a place where electronic equipment is installed; a mounting member on which the electronic equipment is mounted, and which is supported by the base member so as to freely swing about a horizontal base support shaft axis; and an arm member supported by the mounting member so as to freely swing about a mounting member support shaft axis extending horizontally, which sets mounting angle of the electronic equipment by being latched by the base member, whereby the electronic equipment is mounted at a prescribed angle.

Abstract: A magnetic resonance imaging system for interventional MR imaging involving operations to insert a device such as a catheter into an object. According to the system, a tip position of the catheter is detected, data indicative of moved loci of the catheter are produced from data indicative of the detected tip position, and the produced movement locus data are displayed. In addition, even when an operator changes the progress direction of the device such as a puncture needle, an imaging cross section automatically tracks movements of the device. Appropriate preoperative plan means are also provided.

Abstract: The present invention aims to radiate heat efficiently from the inside of an equipment housing, with a simple structure. First and second through air passageways are formed at the sides of first to third equipment housings and the second through air passageway communicates with a recess air passageway to supply air from the first through air passageway into the first to third equipment housings, discharge the exhaust from the first equipment housing directly out of the equipment through a second window portion, and lead the exhaust from the second and third equipment housings into the second through air passageway through the second window portion and the recess air passageway and discharge it out of the equipment.

Abstract: To provide an electronic equipment mounting device having flexibility in the mounting direction, the device is provided with a mounting jig on which a plurality of tongues are formed and a housing whose flat faces having different areas have slits in them, the tongues being inserted into the slits in a detachable manner. The mounting jig is mounted on, for example, the surface of a wall, and then the housing is coupled to the mounting jig by selectively using one of its side faces.

Abstract: Time charts describe time points at which a gradient magnetic field is generated, a radio frequency pulse is sent, a magnetic resonance signal is received, and a load is provided to a patient. At the respective time points described in the time charts, gradient magnetic field coil generates the gradient magnetic field, transmitting/receiving coil sends the radio frequency pulse and receives the magnetic resonance signal, and load providing device provides the load to the patient.

Abstract: An active noise reduction device for reducing the noise produced by cooling fans in a computer. The active noise reduction device comprises a duct mounted on the casing of the computer and having at least one air passage. One end of the passage communicates with the interior of the casing near the cooling fans and the other end is open to the atmosphere. A first microphone is arranged in the duct near the first end opening for detecting noise, and a second microphone is arranged in the duct near the second end opening. A speaker is arranged in the duct near the second opening, and a controller controls the speaker in response to outputs of the first and second microphones for reducing the noise produced in the casing. The speaker makes a sound having a reverse phase to that of the noise produced in the computer and the speaker sound is superimposed on the noise.

Abstract: A signal suppressing apparatus for suppressing undesired signal components, in which a first filter electrically simulating a propagation system A of a physical phenomena such as a sound, vibration, electricity, etc. is mounted; a signal having a correlation to the signal to be input to the propagation system A is input to this first filter; and the output of the first filter exerts an influence upon the signal passing the propagation system A to make the passed signal approximate the intended value, wherein the first filter is split into a plurality of filters, each of which is composed by a discrete DSP, outputs are individually calculated in the split individual filters, and the individual calculation results are tabulated, whereby a value the same as the value obtained where the calculation is made without splitting of the first filter is obtained. This enables high speed signal processing even if a high speed DSP is not used.
