Title: Grinding finishing method for gear
Inventor: OKUNISHI HIROSHI
IPC: B23F19/00
Filed: 1987-06-16
Abstract: PURPOSE:To obtain the optimum engaging condition at the time of assembling with high accuracy and suppress gear noise by carrying out the finishing operation by means of the engaged rotation between a toothed tool and a gear to be machined with the same shaft-to-shaft distance as that in service and the reciprocation of the toothed tool. CONSTITUTION:Toothed tools 2 each corresponding to plural gears 1 to be machined are provided leaving the same shaft-to-shaft interval as that in service and these are selectively engaged, to carry out the finishing operation of the tooth surface of the gear 1 to be machined over the whole area in its tooth length direction by means of the engaged rotation between the toothed tool 2 and the gear 1 to be machined and the sliding contact in the tooth trace direction of the toothed tool 2. Since this engaged rotation speed is not only for the purpose of obtaining a grinding speed, it is also possible to carry out the finishing operation under a low speed condition. And, since the grinding finishing is carried out in an actually assembled condition to a shaft 3, it is possible to obtain the optimum tooth form in a condition that the deflection of the shaft 3, the tilt of bearings 5, 41, 43, error in product, etc. are taken into account, suppressing gear noise.

Filed: 1987-06-17
Abstract: PURPOSE:To omit a high construction cost and to improve the working efficiency by providing the guidelines at the positions on a traveling path of an unmanned vehicle where high position accuracy is required and carrying out the drive control among those guidelines based on the taught operation information. CONSTITUTION:The guidelines are set at least at those points on a traveling path of an unmanned vehicle where the high position accuracy is required.

Filed: 1981-09-24
Abstract: PURPOSE:To cope with frequent extension of individual input sections without decreasing the transmission efficiency of a communication line, by providing a means omitting the transmission of data to the individual input section not returning a signal representing actual devices. CONSTITUTION:An individual input section 1-X and a word scanner 2'' are connected with a control signal bus 6 other than an address bus 4. When an address ADX is outputted, and when the individual input section 1-X assigned with the address ADX is mounted, a decoder 11 discriminates the address ADX transmitted from the bus 4 and outputs ''1'' and makes a gate 12 conductive. On the other hand, when the input section 1-X is not mounted, even if the address ADX is outputted from the scanner 2'' to the bus 4, no control signal CS is outputted to the bus 6. As a result, a gate 24 of the scanner 2'' is conductive, a clock signal CL immediately advances a step counter 21 by one step via gates 24 and 23 and outputs the next address.

Title: Electrophotographic receptor
Inventor: YASHIKI YUUICHI
IPC: G03G5/02
Filed: 1980-10-28
Abstract: PURPOSE:To avoid the deterioration of the characteristics of a photoconductive zinc oxide layer due to a photosetting resin and to obtain a receptor enabling the repetition of wet development by interposing an emulsion resin layer between the zinc oxide layer and a layer of the photosetting resin. CONSTITUTION:On a photoconductive zinc oxide layer an emulsion resin layer is formed, and a photosetting resin is coated on the emulsion resin layer and set to form a layer. Since the photoconductive layer has a porous surface, when the photosetting resin is directly coated, the resin soln. penetrates the photoconductive layer, and the layer is eluted, resulting in deteriorated characteristics. The emulsion resin prepared by dispersing resin particles in water does not penetrate the photoconductive layer and causes no elution because the solvent is water. The especially suitable emulsion resin is an acrylic emulsion. For example, the acrylic emulsion is suitably diluted with water, coated on the photoconductive layer, and dried.

Filed: 1978-12-06
Abstract: PURPOSE:To improve corrosion resistance and wear resistance of a cylinder for printing press by forming a plasma flame-sprayed coat of an alloy on the outside peripheral surface of a cast iron cylinder base member. CONSTITUTION:The outside peripheral surface of a cast iron cylinder base member for use as a base material of an offset press plate drum or the like is subjected to blasting for an activation treatment of a surface roughness of about 20mu. After preheating the cylinder base member to a temperature of 100-150 deg.C, an alloy containing 12-16wt% of Ni, 16-18wt% of Cr, and 2-3wt% of Mo, the remainder being Fe, is flame-sprayed onto the surface of the base member in a thickness of about 300mu by plasme irradiation. Because the alloy composition falls into the range of austenitic stainless steel, the obtained coat has less iron oxides mixed therein, less pin holes present therein, better corrosion resistance and wear resistance, and is minuter in structure than those formed by flame spraying of other materials.

Further, the highly rigid molding is obtained by molding the skin unwoven fabric layer 2 to be of a higher density than the core material unwoven fabric layer 1.  Besides, when laminating the skin unwoven fabric layer 2 to the core material unwoven fabric layer 1, it is preferably to arrange the fibers in respectively different directions and thereby, further increase the rigidity of the molding.
