Title: Rootcrop harvester
Inventor: KAWAGUCHI HIROMICHI
IPC: A01D25/00
Filed: 1995-05-17
Abstract: PURPOSE: To provide a rootcrop harvester subject to no limitation of harvest per unit area of the field depending on its structure. CONSTITUTION: This rootcrop harvester stands equipped with a plural sets of a pair of digging/gripping conveyer belts 10 to dig crops by directly gripping the roots in front of the harvester and rotating oppositely to each other and arranged either tiltedly or horizontally with different levels relative to the ground. When the respective belts 10 are arranged in the same direction and nearly at the same tilt angle against the ground, the intervals between rootcrop plating rows adjacent to each other can made narrower as compared to the case with horizontal arrangement of these belts relatively to the ground, thereby such an arrangement leads to greater harvest per unit area of the field. Besides, tilted arrangement of the belts increases rootcrop gripping force, resulting in greater rootcrop pull force and being effective in the case of hard soil and large-sized rootcrop harvesting.

Title: Transistor circuit
Inventor: FUKUSHIMA ISAO
IPC: H03F3/34
Filed: 1982-07-09
Abstract: PURPOSE:To obtain a power transistor driver having a small IC chip size with low power consumption, by providing a bipolar transistor TR and an MOS-FET on the same IC chip and making an MOS-FET a TR to supply power. CONSTITUTION:The output current of a differential amplifier consisting of bipolar TR1 and TR2 and a TR3 is converted into voltage signals by a P-channel MOS TR. The relationship between the drain current and the gate-source voltage of the MOS TR is decided by the width W and the length L of the gate. Then W/L is the larger, the larger drain current is obtained to the given gate- source voltage. Therefore no gate current is needed despite an increment of undesired current of an MOS TR27 by increasing the W/L of the TR27 compared with the W/L of an MOS TR26 and in response to a desired current. Thus only the size of the TR27 is increased to obtain a current required for driving a power TR9. As a result, the size can be reduced for TR1, TR2 and TR3 respectively.
