Title: Locking device for agricultural land grading carrier
Inventor: KUMAGAI TOSHIO
IPC: E02F3/40
Filed: 1984-09-20
Abstract: PURPOSE:To prevent the occurrence of unexpected dumping, by a method wherein a carrier is pivotally supported to a mounting frame so that it can freely dump, a hook, engaged with the locking rod of the carrier, is attached to the upper part of the mounting frame, and a lock pin serves to prevent disengagement of the hook. CONSTITUTION:A mounting frame 6 is vertically movably located to a tractor 1, and a box from carrier 10, being open at the upper part, is mounted to the mounting frame 6 through the medium of a shaft 9 so that it can freely dump. A hook 11, engaged with a locking body 24 of an upper frame 20, is located to the upper part of the mounting frame 6. When the carrier 10 is not needed to dump during carriage and the like, a lock pin 26 is inserted through a through-hole 27 formed in a longitudinal lever 22 of the upper frame 20, and this prevents the hook 11 from being rotated for disengagement from the lock body 24. This prevents the carrier 10 from unexpected dumping, resulting in the possibility to ensure safety.

Abstract: PURPOSE:To accurately and easily perform close positioning by visual observation by projecting light which contains information on a marked line on a scanning surface and forming the image of the marked line on the scanning surface, and expanding and observing visually this image and its peripheral scanning surface. CONSTITUTION:Light emitted by a light source 11 is converted by a condenser lens into a nearly parallel light beam, which is projected on a target 13 where the marked line is formed as an optical target. Light which contains the information on the marked line by passing through the target 13 is projected on the surface of an original picture stuck on an original picture cylinder 4 as the scanning surface through a projection lens 16 and a half-mirror 17. Thus, the image of the marked line formed directly on the original picture 5 is enlarged through a close-up lens 20 together with its peripheral scanning surface and observed visually by an operator vertically. Thus, the wide area on then original picture 5 is enlarged and viewed, so close positioning is easily performed.

CONSTITUTION:At the time when necessary exhaust is finished e.g. at the end of cooking, a large-sized fan 13 for exhaust is stopped from rotating to close a front shutter 17 and heating is started in conduction of a heater 19. In this condition, the poles of an electromagnet 20 are changed by switching to provide an attraction relation between a permanent magnet 21; therefore, the large sized fan 13 is attracted in the direction of a motor 12 and engaging between a pin 23 and a notching part 24 at the tip end of a fan boss is released and rotation of the motor 12 is not transmitted and the large-sized fan 13 is stopped; however, the small-sized fan 14 is continued to rotate. Necessary temp. for heating is temp. necessary to decompose oil by catalyst and oil caught by a filter 16 is decomposed by the action of the catalyst attached to the filter to generate waste gas. At that time, the small-sized fan for exhaust of decomposed waste gas is continuing to rotate and a back shutter 18 also keeps open condition and therefore, decomposed waste gas is exhausted.

Title: Electric device
Inventor: ERUNSUTO BUREMU
IPC: H02K5/15
Filed: 1985-09-10
Abstract: In turbo-generators with hydrogen-cooled rotor windings, one-piece end casings are used to avoid complicated sealing positions. These end casings are strongly ribbed in a radial direction and present difficulties when installing the shaft seal (19). Furthermore, they do not permit any inspection openings in the ribbed end casing. Both have the final result of causing an increase in the machine length. Due to the pot-type design of the end casing (1) with a vertically extending channel-type recess (9) having a width greater than the rotor outer diameter, the assembly of the splert ring (19) is facilitated. The channel walls (7, 8) stiffen the end casing and provide niches which are accessible from the end face of the machine via inspection openings.

Abstract: PURPOSE:To improve an operation speed by a method wherein a gate electrode is composed of a plurality of polycrystalline silicon layers and the impurity concentration of the lowermost polycrystalline silicon layer is made to be high and an oxide film is formed over the polycrystalline silicon layers. CONSTITUTION:A gate oxide film 2 is formed on a silicon substrate 1. Then a polycrystalline silicon layer 3 containing a large quantity of phosphorus as impurity is built up and a polycrystalline silicon layer 4 containing a small quantity of phosphorus as impurity is built up on it. Then the layer 3 and the layer 4 are formed in to a required pattern by a photolithography technology to form a gate electrode. An oxide film 5 is formed by a thermal treatment in an oxygen atmosphere.

The source and drain regions 6 of a transistor are formed by ion implantation technology and self-alignment technology. If the thickness of the oxide film 5a is controlled, the operation speed can be improved without increase of the parasitic capacitances between the source and drain regions and the gate electrode.
