Title: Power amplifing circuit
Inventor: HAYAMA KAZUHIRO
IPC: H03F3/30
Filed: 1978-10-24
Abstract: PURPOSE:To enable a power amplifier, supplied with input signals from a source- follower circuit of FET, to operare even at a high frequency by holding the drain- source voltage of FET nearly constant. CONSTITUTION:Drains of N channel FETs Q7 and Q8 constituting a source follower circuit are connected to the common-emitter connection point of transistors Q3 and Q4, and resistances R12 and R13 are to that of transistors Q1 and Q2. Then, when an input signal is applied to input terminal 1, both common emitter connection points are held at nearly-constant potentials even if the input signal would change in amplitude since transistors Q1 and Q2, and Q3 and Q4 constitute differential amplifiers respectively. Therefore, drain-source voltages of FET Q7 and Q8 are nearly constant, so that the Miller effect will not be caused.

Title: Image pickup type border detecting device
Inventor: FUJII YASUO
IPC: A01B69/00
Filed: 1987-05-27
Abstract: PURPOSE:To accurately detect a straight line corresponding to a border between an unmowed working place and a mowed working place without being affected by a shadow by performing retrieval in a dark-to-light direction which crosses the border at right angles, and extracting the picture element which appears first among picture elements extracted by a binarization means. CONSTITUTION:When a lawn member 3 is mounted on a working vehicle and mowing operation is performed, an image sensor S1 picks up an image of a working place in front of the vehicle body and the phenomenon that a unmowed place B is seen darker than a place which is already mowed is utilized to detect the border. At this time, a differentiating means quantizes picked-up image information and calculates a differential value of brightness variation. Then the binarization means extracts only a picture element where the absolute value of a differential value becomes larger than a preset threshold value and a picture element extracting means extracts the picture element which appears first among the picture elements extracted by the binary coding means to remove the shadow in a bright part. Then a straight line arithmetic means detects the straight line corresponding to the border L1 by using huff conversion.

IPC: B60L15/20
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To make a vehicle move forward merely by loosing a brake pedal, even though the brake pedal is not returned completely in its operation. SOLUTION: When a pressed stroke of a brake pedal 92 is decided to be lower than prescribed level by a stroke decision means 96, driving torque necessary for making a vehicle move forward is generated from a motor generator 14 through a forward going torque output means 102. The vehicle is driven forward with torque according to a decrease in the stroke of the brake pedal 92, even at running in congestion on a road. Then, the vehicle can be made forward even on the congested road only by loosing the brake pedal 92 and by adjusting the stroke of the brake pedal 92, without completely returning the brake-pedal operation. In this way, troublesome operation of forward driving with complete release of the brake pedal is not required at congestion running that requires frequent slow advance of the vehicle.
