摘要： A Mo side component is added to the essential component of a piezoelectric ceramic composition containing Pb, Zr, Ti and O, in an amount of from about 0.06% by weight to about 5.0% by weight, in terms of MoO.sub.3, relative to the amount of the essential component. Preferably, the side component is added to the calcined essential component, and the resulting mixture is fired to give a sintered piezoelectric ceramic composition. The addition of the side component improves the low-temperature sinterability of the piezoelectric ceramic composition without worsening the piezoelectric characteristics of the composition.

摘要： In order to record content on a hard disk drive to a source, when a source icon corresponding to the hard disk drive is dragged in a source icon section on a control bar in a display window, an arrow is added above an available source icon corresponding to an MD drive to which the content read from the hard disk drive can be supplied and recorded. An unavailable source icon corresponding to a source to which the content cannot be supplied and recorded is displayed in a grayed-out manner. When the dragged source icon is dropped onto the source icon corresponding to the MD drive, the content on the hard disk drive is read, and is recorded to an MD inserted in the MD drive.

摘要： An inverter apparatus includes an inverter circuit, a temperature sensor, and a control circuit. The inverter circuit is driven by a PWM signal and includes switching elements that are divided in first and second groups. The temperature sensor detects a temperature of at least one of the switching elements of the first group. The control circuit controls a duty cycle of the PWM signal such that a first value of heat generated in the first group is equal to or greater than a second value of heat generated in the second group. The control circuit performs an overheat protection for protecting the inverter circuit from overheating when the detected temperature is equal to or greater than a threshold temperature.

摘要： In a secondary air injection system, MOSFETs control supply of electric current to an air pump and to a motor for driving an electromagnetic valve and to an electromagnetic coil to introduce secondary air into an exhaust gas passage upstream of a catalyst for purifying the exhaust gas of an internal combustion engine. Gate drive circuits control the MOSFETs based on an instruction from an ECU via input signal processing circuits. Abnormal conditions in the operation for controlling the air pump and the electromagnetic valve are detected, and, when an abnormal condition is detected, forcibly turn the MOSFETs off to interrupt the current to the motor and to the electromagnetic coil. A diagnosing circuit sends to the ECU diagnosis signals representing the state of controlling the load.

摘要： To realize an information processing apparatus for editing data which enables editing of data intuitively with a simple operation. A track segment is displayed at a position corresponding to a track number on a first coordinate axis in a track segment display area, with a range corresponding to the period from the start time to the end time of the track on a second coordinate axis, so that it is possible to intuitively notify a user of the place in the order and the performance time of each track based on the position relationship among track segments and the length thereof. Furthermore, in response to an operation to move a track segment along the first coordinate axis, the track number of a track corresponding to the track segment is changed; the order of tracks is also changed; and in addition, the track segment is displayed as having moved to the position corresponding to the changed track number and the changed place in the order. Thereby, it is possible for the user to easily change the order of tracks with an intuitive operation.
