摘要:
A thin-film temperature sensor with a robust bridge structure and a stable electric characteristic, as well as a method of manufacture thereof, is provided. Over the substrate 1 with the cavity 13 are formed electrode layers 6 in a bridge shape, whose electrodes 6A, 6B are bonded with thermal sensitive resistor films 7, 8, which are then covered with a protective insulating film 9, a buffer film 10 and a glass layer 11 in that order. The protective insulating film 9 and the glass layer 11 extend over the substrate 1 to increase the mechanical strength of the infrared sensitive element A. The sandwich structure of the insulating films 5, 9 holding the thermal sensitive resistor films 7, 8 in between and the use of the buffer film 10 combine to prevent electrical characteristic variations, which would otherwise be caused by changes in composition of the thermal sensitive resistor films 7, 8 during the heat treatment process. The glass layer 11 is formed of borosilicate glass to improve its infrared absorption characteristic.

Chord to be performed is presented to a user. Chord is detected based on one or more notes performed by the user. When it is not detected that a chord has been duly established, one of the notes performed by the user is detected as a root note of a chord. Comparison is made between the chord presented to the user and the detected chord to make a determination as to whether at least the root note of the detected chord matches the root note of the presented chord. The user is informed of a result of the determination. Thus, not only when the user has accurately executed performance operation for all component notes of the presented chord but also when the user has executed performance operation for only the root note of the presented chord, a chord performance evaluation is made, determining that the user has accurately performed.

A clock signal generator circuit has a clock generator for generating clock signals to be supplied to a central processing unit and to functional blocks, and clock selectors. The clock generator divides the frequency of a source clock signal, to form a clock signal having an optional period. Namely, the clock generator suppresses at least one active or inactive state of the source clock signal, to generate a clock signal whose period is an integer multiple of that of the source clock signal. The clock selectors receive the clock signals generated by the clock generator and selectively supply them to the CPU and functional blocks. The clock signal generator circuit is capable of operating a microcontroller system at a required minimum speed, to optimize the power consumption of the system.

An ink-jet recording apparatus quickly completes a preparatory driving operation, and suppresses the wasteful consumption of the ink even if the apparatus is used in a cold environment after the apparatus has been held inoperative for a long time. The ink-jet recording apparatus comprises a first storage for storing a first driving pulse width data, a second storage for storing a second driving pulse width data, and a plurality of driving pulse generating units. A data selecting unit selects either the first driving pulse width data or the second driving pulse width data according to selection data set by a dot counter control unit, and a print pulse width setting unit and the driving pulse generating units generate ink-jet print head driving pulses. A print data processing unit produces print data for driving the nozzles of the ink-jet print head. The first and second driving pulse width data is used selectively and the print data is produced according to the time for which the ink-jet recording apparatus has been held inoperative and the temperature of the ink-jet print head.
