Abstract: PURPOSE:To contrive to prevent the scattering of mowed grasses outside a mowed grass receiver and smoothly bring the receiver into contact with a cover by disposing in the cover a contact section for bringing the upper edge portion of the opening of the receiver into contact with the cover from the upward direction. CONSTITUTION:The front portions of a pair of right and left cross-sectionally U-shaped arms 21 having pins 20 inwardly projected at the rear ends of the arms are securely attached to both the ends of a support shaft 5, respectively. A cover 14 having a flange-like contact section 3 for contacting with a support frame 18 from the upward direction and a peripheral edge portion 22 suspended from the contact section 3 is disposed on the upper support frame 18. Notch portions 23 capable of engaging with the supporting shaft 5 and the pin 20, respectively from the upward direction are disposed on the peripheral edge portion of the cover 4, and hooks 17a capable of engaging with the pins 20 from the upward direction are disposed on both the right and left sides of the upper support frame 18.

Title: Surge protection circuit
Inventor: UEDA NORIYUKI
IPC: H03K19/018
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To make it possible to definitely prevent the break of an element or malfunction of a circuit, by performing a surge protecting operation for controlling the conduction of a protective transistor. SOLUTION: If a terminal-to-terminal voltage of a diode circuit 6 comprising a group of diode elements connected in series is Vn, then a transistor 4 becomes conductive and is turned to ON state when a surge voltage is applied to an input circuit of a semiconductor IC circuit 1 and a voltage higher than VBE+Vn is applied as a voltage between the base and the emitter of the transistor 4. By doing this, a current flows between the emitter and the collector of the transistor 4, and this current flows to the base of the transistor 5 and the transistor 5 becomes conductive. This transistor 5 takes in a surge current which tends to flow to the internal circuits through a surge protection resistor 2, and releases it to the grounding section GND. By a series of these operations, the surge resisting capacity can be improved.

Abstract: PURPOSE:To eliminate resiliency which operates between magnets, increase the density of magnetic flux atop a group of recording electrodes, and secure the space where a toner removing conveyance system is provided by arranging a magnetic body plate between magnetic poles of the magnets arranged across the recording electrode group. CONSTITUTION:An iron wire with a 20mum diameter is used as a recording electrode 7 and 3,360 pieces of recording electrodes are arranged over a 210mm. width.

A recording medium 1 faces the recording electrodes 7 almost at right angles. The electrodes 7 is sandwiched between the two magnets 8 arranged so that the same poles face each other, resiliency is eliminated because of the presence of the plate 12 and the magnets 8 rather attract each other across the plate 12. Further, the density of magnetic flux atop of the electrodes becomes larger than when the plate 12 is not provided, so the distance between the magnets 8 and recording medium 1 is set to >= about 1cm, and the space for the system which conveys toner staying near the magnets 8 is secured.
