Abstract: PURPOSE:To enable the enhancement in heating efficiency by providing all around an intermediate cylindrical part having electrical and heat insulating properties so as to cover all the heat generating bodies, and providing an outer cylindrical part having electrical and heat insulating properties to cover all the circumference of said intermediate cylindrical part. CONSTITUTION:In a heater 33 to be fixed to an insulator placed between a carburetor and an intake manifold, an intermediate cylindrical part 36 being made of synthetic resins and having electrical and heat insulating properties is provided all around so as to cover all the heat generating bodies 32. Further, all the circumference of said intermediate cylindrical part 36 is covered by an outer cylindrical part 37 being made of synthetic resins and having electrical and heat insulating properties. Accordingly, by the existence of both cylindrical parts 36, 37, especially by the multiplication effect together with the insulating effect of the outer cylindrical part 37 because all the heat generating bodies 32 are covered by the intermediate cylindrical part 36, the heat due to the heat generating bodies 32 becomes difficult to be radiated to the outside, thus the heating of the fuel flowing through a passage 30 on the inner circumferential surface side can be sufficiently carried out, enabling the enhancement in heat efficiency.

Title: Driving gear for brushless motor
Inventor: SHIMAZAKI TSUTOMU
IPC: H02P6/10
Filed: 1994-03-30
Abstract: PURPOSE:To inhibit the rotational unevenness (a jitter component) of a motor. CONSTITUTION:The switching of the output transistors Q1-Q6 of an output section 12 is controlled, and the specified currents of three layers are made to flow successively through coils L1-L3, thus driving a motor. The torque command of the motor is generated by comparing an FG as the signal of the revolution of the motor and the phase of a reference clock by a PLL control section 22. On the other hand, a PWM generating section 50 determines the power-supply side voltage VM of the output transistors Q1-Q6 from the state of the fluctuation of driving voltage to the motor. Since both the PLL control section 22 and a PWM control section are operated by a reference clock from a reference-clock generating section 40, the fine change of motor supply currents resulting from the mutual intervention of signals can be inhibited, thus preventing the rotational unevenness of the motor.
