Title: Starter generator
Inventor: UCHIYAMA HIDEKAZU
IPC: H02P9/14
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a starter generator which can easily and effectively realize motor characteristics by a variable field system at a low cost. SOLUTION: A starter generator for a small-sized two wheeler, which consists of an armature coil 1 of a synchronous DC brushless motor, a field coil 2, a power supply 3, a motor driver and commutator/voltage regulator 4, etc. When the generator operates as a motor, it is supplied with power from the power supply 3 in a direction such of increasing the effective amount of magnetic flux to the field coil 2, and when it is started up, a large current flow is caused to flow also into the field coil 2 and therefore the generator works as a low rotating speed and high torque type motor. As the rotating speed increases, the current flow into the armature coil 1 decreases, and a current flow into the field coil 2 also decreases together with the decrease in the current flow into the armature coil 1, automatically shifting the generator to a high rotating speed and low torque type motor.  When the generator generates power, the current flow in the armature coil is reversed, and therefore the current flow direction into the field coil 2 is also reversed from the case, when the generator works as a motor, and larger the output is due to increase in rotating speed, the generator is acted to work in such a direction as to decrease the effective amount of magnetic flux.

Abstract: PROBLEM TO BE SOLVED: To make a display part small-sized by dividing electronic components into blocks of short components and tall components, and arranging the short components opposite a liquid crystal display part on a substrate and the tall components at the outer periphery on the same side with the liquid crystal display part. SOLUTION: The substrate 111 consists of a substrate constituting an inverter circuit for an LCD back light and a substrate constituting a circuit for a CCD camera unit and is arranged on both the sides of an image pickup part. Then a tall component 112 is arranged projecting from an LCD 21 along the outer periphery of the LCD 21 and the short component 113 is arranged opposite the back of the LCD 21 across the substrate. In this case, the electronic components are divided into the tall component 112 and short component 113 and the tall component 112 is arranged at the outer periphery on the side of the LCD 21, so its upper end never projects from the top surface of the LCD 21. Further, only the short component 113 is mounted on the substrate 111, so the thickness of the LCD 21 is reducible.
