Title: Lowering voltage circuit
Inventor: GOTO HIROSHI
IPC: H01L27/04
Filed: 1997-08-12
Abstract: PROBLEM TO BE SOLVED: To make current consumption at a stand-by time small by generating a reference voltage while operating a TFT(thin film transistor) in a suturated current area and obtaining a low power source voltage while controlling a transistor for lowering a voltage by the reference voltage to make the low power source voltage not to be more lowered when a power source voltage is sufficiently low and to make a voltage rising due to a temp. rising small. SOLUTION: A Tr3 is constituted of a TFT and Tr4, Tr5, Tr6 are respectively constituted of N-channel MOS transistors. A voltage to be lowered by the Tr3 by using the Tr3 as a load resistance, that is, as a minute and constant current source is made to be a reference voltage to be determined by the number of stages in which the transistors Tr4, Tr5 are connected in series. Consequently, a power source voltage VCC from the outside is lowered to a low power source voltage VDD with the Tr6. Thus, since the suturated current of the Tr3 is decreased at a high temp. as compared with that at a room temp., the voltage characteristic of the low power source voltage VDD is improved and the increasing of current consumption at the time of a stand-by is made small even when the power source voltage VCC is increased.

Title: Resin made pulley
Inventor: HARADA TOSHIRO
IPC: F16H55/36
Filed: 1990-08-18
Abstract: PURPOSE:To reduce resonance of a pulley when a belt taps the pulley, restrict generation of abnormal sound or strength deterioration, and reduce a wind howling noise of a rib by making distances between adjacent respective ribs into unequal pitches and arranging the unequal pitches irregularly. CONSTITUTION:A pulley 1 is provided with unequal pitches P1 to P6 between adjacent respective ribs 3a to 3f and because of irregularly arranged respective unequal pitches P1 to P6 the outer peripheral surface of a rim 4 after resin forming is shaped in a polygonal shape having no regularity. Accordingly, when running is performed while keeping a timing belt or V-ribed belt in contact with the outer peripheral surface of the rim 4, each belt does not tap the pulley 1 periodically, that is to say, continuous timings to tap the pulley 1 by each belt become irregular. Thereby the vibration level of the pulley 1 by the tapping changes irregularly, resulting in no resonance and the vibration is not amplified. Further, a change of wind howling noise of respective ribs 3a to 3f is not periodic, and the frequency of the noise is disturbed to restrict a beat sound.
