Title: Thin-film transistor and its manufacture
Inventor: KOMORI KAZUNORI
IPC: H01L21/336
Filed: 1992-11-20
Abstract: PURPOSE:To achieve a reverse exposure process and to obtain a thin-film transistor which can be manufactured easily and has improved characteristics by setting the total film thickness of a semiconductor layer and a semiconductor layer including impurity ions to a specific range. CONSTITUTION:A gate electrode 2 is subjected to film-formation patterning onto a glass substrate 1 and then a gate insulation film 3, a semiconductor layer 4, and a protective insulator layer 9 are formed on the substrate 1. The protection insulator layer 9 is patterned to a specific shape and then a semiconductor layer 6 including impurity ions is formed on it. At this time, the total film thickness of the semiconductor layer 4 and the semiconductor layer 6 including impurity ions is set to 10nm or more and 90nm or less. Therefore, the semiconductor layer 6 including impurity ions and the semiconductor layer 4 can be subjected to patterning simultaneously by a reverse exposure process, thus obtaining a thin-film transistor with improved characteristic by easy manufacturing.

Title: Drive circuit for brushless motor
Inventor: NIIKURA HIDEO
IPC: H02P6/08
Filed: 1989-11-30
Abstract: PURPOSE:To suppress noise by a method wherein a signal, changed before a position whereat the current of a coil is switched, is produced logically to integrate it while a waveform, whose upper and lower parts are clipped, is added in respective phases to make a driving signal for switching the current of the coil. CONSTITUTION:The position sensors 1a-1c of a rotor magnet are provided near the current input side of three-phase driving coils Lu-Lw. Comparators 3a-3c detect zero-cross points from the position sensors 1a-1c to produce signals (a1)-(a3), changed at the zero-cross points of counter electromotive voltages of respective driving coils. The logical operations 5 of the signals (a1)-(a3) are effected to output signals (b1)-(b3), which are changed with the intervals of 120 deg., and a signal (c) changing at all zero-cross points. The signal (c) is integrated in an integrating device 6 to produce triangular waves (d1), (d2) having reverse phases to each other while truncated wave signals (e1), (e2) are produced by clippers 7a, 7b. Transistors Q1-Q3 are put ON/OFF by signals (f1)-(f3), obtained by operating the signals (b1)-(b3) and signals (e1)-(e3) through operating circuits 8a-8c. According to this method, a voltage is changed smoothly and driving noise may be suppressed.

Title: Telephone set
Inventor: SUZUKI MIKIO
IPC: H04M1/00
Filed: 1987-12-11
Abstract: PURPOSE:To properly keep the sound volume of a call tone even if the noise level is changed by detecting the sound level around a telephone set main body at a surrounding noise detection means and outputting a call tone in a sound volume in response to the detected sound level. CONSTITUTION:A signal having a level in response to the sound volume of an external noise of the telephone set is outputted from a microphone 6 and a control section 5 sets an amplification factor proportional to the level of the signal to an amplifier 2. When a call signal is sent from an exchange (not shown) to the telephone set, a switch circuit 3 is subjected to on/off control and the output signal of the oscillator 4 is amplified by the amplifier 2 to output a call tone from a speaker 1. In this case, when the output signal of the oscillator 4 is detected at the output of the amplifier 2 by a reset circuit 7, since the amplification factor set by the control section 5 is fixed, the sound volume of the call tone becomes the volume based on the noise level just before the start of the output of the call tone.
