An inverting negative voltage DC-DC power supply circuit comprises a first resistor having one end connected to an output terminal for converting a change in output voltage into a current. A zero-volt clamp circuit is connected to the other end of the first resistor and comprises a first and second transistor. A current mirror circuit comprises a third and fourth transistor and is connected to the zero-volt clamp circuit for causing a current of the same value as that of a current flowing in the zero-volt clamp circuit to flow. A second resistor is connected to the current mirror circuit for converting a change in current flowing from the zero-volt clamp circuit into a voltage.

The present invention I related to a contents provider supplies encoded contents to a transmitting station, and broadcasts the encoded contents via a satellite. At a gas station inside a service area of the satellite, a base station to receive the contents from the satellite is disposed. The contents provider transmits to each base station decoding keys to decode the transmitted contents via the Internet. The base station relates the received contents to the decoding keys to store in a large capacity memory. When a vehicle stops by at the gas station, a vehicle-mounted apparatus communicates with the base station so as to download the contents, accumulate in a memory, and reproduce. This enables digital contents to be distributed to a mobile body with small-scale equipment.

A charging apparatus includes a DC-DC converter for stepping down a charging input voltage, and a charging current controller having two input terminals and one output terminal. The input terminals receive a voltage based on a charging current drawn from a voltage stepped down by the DC-DC converter. The voltage at the output terminal serves as a control voltage for controlling the charging current drawn from the stepped-down voltage.

To provide a pitch waveform signal division device and the like for making it possible to compress a data capacity of data representing a sound efficiently. A computer C1 arranges time lengths of sections for a unit pitch of sound data, which the computer C1 compresses, to be identical to thereby generate a pitch waveform signal, detects a boundary of adjacent phonemes included in a sound represented by the pitch waveform signal and an end of this sound on the basis of intensity of a difference between two sections for adjacent unit pitches of this pitch waveform signal, divides the pitch waveform signal in the detected boundary and end, and outputs obtained data as phoneme data.

A method to check a tissue located in the vicinity of an object of examination when a treatment instrument such as a puncture needle is inserted into a subject, wherein a first planar image construction block included in an image construction unit reconstructs in real time two-dimensional planar images, which represent subject's slice planes, on the basis of projection data. A stereoscopic image construction block included in the image construction unit constructs three-dimensional stereoscopic images, which represent the subject's slice planes, on the basis of projection data. The planar images constructed by the first planar image construction block are displayed in real time on the screen of a display unit, and the stereoscopic images constructed by the stereoscopic image construction block are displayed on the screen of the display unit while being juxtaposed with the first planar images constructed by the first planar image construction block.

The invention prevents a clutch from being damaged and ensures a driver of a feeling of responsiveness even if an accelerator pedal is depressed when an automatic transmission is shifted from a drive range to a non-drive range. If neutral has been selected and if an accelerator has been operated, an ECT_ECU performs normal throttle control until lapse of a first period of time following operation of the accelerator exceeds a second threshold. Within a second period of time following the first period of time, the ECT_ECU executes a program including the regulation of throttle opening at less than the amount corresponding to degree of accelerator depression in normal control, until lapse of a predetermined time subsequent to detection of the shift.
