IPC: G03G15/09
Filed: 1982-04-20
Abstract: PURPOSE:To obtain a magnetic circuit device being readily assembled by a construction wherein some of the magnets corresponding to the number of magnetic poles on the peripheral surface of the roll of a magnetic substance form main magnetic poles themselves in such a manner that each becomes an auxiliary pole for the adjacent ones. CONSTITUTION:Resin-combined type magnets M1-M6 are arranged around the axis 1 of a ferromagnetic substance and magnetized so that each of the axes easily magnetized is directed as shown by an arrow. The magnets M1-M6 are main magnets corresponding to the number of magnetic poles required on the periphery of the roll of a magnetic substance, respectively. To make M5 an auxiliary pole of M6 regarding a set of adjacent M5, M6, they are directly in contact with each other between the axis 1 and the peripheral surface 2 of the roll in such a manner that the magnetizing direction of the magnets and their directions of orientation corresponding thereto are perpendicular to each other. With this construction, the magnetic force of the magnet M6 having the magnetizing direction perpendicular to the magnetizing direction of the magnet M5 functioning as an auxiliary pole is increased. For this reason, a magnet for providing an auxiliary pole is unnecessary and the magnetic force can be increased only by so arranging the magnets. Thus even if the magnet is of the resin-combined type, after processing will not be required.

Title: Fabrication of semiconductor device
Inventor: SATOU SAYURI
IPC: H01L21/324
Filed: 1995-03-24
Abstract: PURPOSE: To form a heavily doped junction shallower than a conventional one by opening a window for diffusion in an insulation layer, growing a semiconductor layer in a mixture gas atmosphere containing two kinds of ion species having different diffusion rate, and then diffusing the impurities from the semiconductor layer into the substrate through heat treatment. CONSTITUTION: A window 7a for diffusion is opened at a predetermined position in an insulation layer 7 formed on the surface of a semiconductor substrate 1 and then a semiconductor layer 8 is grown in vapor phase on the substrate in a mixture gas atmosphere containing two kinds of ion species having different diffusion rate. Subsequently, the impurities are diffused from the semiconductor layer 8 into the substrate 1 through heat treatment thus forming a junction. For example, a polysilicon layer 8 is in vapor phase in a mixture gas atmosphere containing boron and arsenic before being subjected to heat treatment. Consequently, a p-type diffusion region 9 and an n-type diffusion region 10 for providing a base-emitter junction are formed simultaneously because the diffusion rate of boron is higher than that of arsenic by a figure or more.

Title: Pile-up device for veneer
Inventor: NISHIMURA RITSUO
IPC: B65H29/26
Filed: 1985-04-01
Abstract: PURPOSE:To enable shock from piling to be relaxed by detecting the relative movement of a pressing body which is supported through the medium of a shock absorber, so as to control the vertical movement of the pressing body when veneers which have been conveyed while having been partially held, are pressed and lowered down by means of the pressing body to be piled up on a pile-up table. CONSTITUTION:Wood veneers 1 and 2 are conveyed to the left while being supported by conveyors 3 and 4 at their both ends. When the tip ends of them are detected by phototubes 5 and 6, the conveyors 3 and 4 are suspended through a controller 15. Simultaneously, a servo motor 12 is operated allowing a pulley 13 to be rotated counterclockwise, this causes a supporting body 9 which is attached to a belt 14, to be lowered. Subsequently, a pressing body 8 which is arranged at the lower end of the supporting body 9, allows the wood veneers 1 and 2 to be deflected downward in order permitting the veneers 1 and 2 to be piled up in a polymetric form on a pile-up table 7. At this moment, the pressing body 8 comes close to the supporting body 9 each other allowing a rod 11 to go into a cylinder 10. When a proximity switch 16 is turned on by the rod, the servo motor 12 stops once and then starts rotating reversely allowing the supporting body 9 to be elevated.

Abstract: PURPOSE:To permit on/off control of light of only the specific wavelength by controlling photoprojection to a transparent optical cell contg. a photochromic soln. essentially consisting of the assemblage of bacteriorhodopsin. CONSTITUTION:The square transparent optical cell 7 contg. a soln. of a purple film which is the assemblage of the bacteriorhodopsin is disposed in a sample chamber 4 and the control light of a control light source 8 for optical switching different from the light from a light source 2 is projected through a lens 9 and a stop 10 to the cell 7. While the transmittance of yellow light (light of 560nm wavelength) is about 20% in a dark state, said transmittance attains 82% under the projection of the control light 8. This optical switch is usable for formation of on/off signals and transmission control of light information in the case of using light as information. The speeding-up of the reaction of the color change up to order of microsecond is permitted by selecting the reaction system of the bacteriorhodopsin. The high-speed element is thus obtd.

Title: Vacuum cleaner
Inventor: ISHIZAWA AKIHIRO
IPC: A47L5/14
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To continue cleaning while suppressing the temperature rise of a motor-driven blower. SOLUTION: By the drive of the motor-driven blower 13, dust is sucked from the suction port 51 of a suction port body part 3 together with air and captured through a suction air path into the dust collecting chamber 12 of a main body part 2. Filtered air is discharged from the discharge opening 27 of the motor-driven blower 13 into a motor-driven blower chamber 14 as ejection air. The ejection air is partially discharged from the discharge port of a discharge chamber and blown through an ejection air path 101 to a floor surface and the dust is blown up and sucked from the suction port 51 again. When the temperature of the motor-driven blower 13 is elevated by dust clogging, the temperature rise of the motor-driven blower 13 is detected by a first temperature sensor 38a.  The temperature rise of the ejection air is detected by a second temperature sensor by the closing of the discharge port. The input of the motor- driven blower 13 is reduced and the damage to the motor-driven blower 13 is prevented by cooling by natural cold radiation in a state capable of cleaning.

Title: Image reader
Inventor: TANIMIZU HIROMI
IPC: H04N1/19
Filed: 1990-03-19
Abstract: PURPOSE:To always guarantee proper picture quality by providing the image reader with a signal correcting means and individually correcting an image signal obtained from a photoelectric conversion cell detected by a cell abnormality detecting means out of image signals obtained by an image sensor and outputting the corrected signal. CONSTITUTION:Address data (x) latched from a latch circuit 9 at the time of an abnormality cell detecting mode and address data (y) outputted from an address generating circuit 8 are applied to a comparator 10. Because the inputs of the comparator 10 are different at first, the data of a latch circuit 11 is sent to an output terminal 14 since the output of the comparator 10 is selected to input to a terminal A of a selector 13 in the case of discriminating x=y. When the value (y) outputted at the time of outputting an image signal from the photoelectric conversion cell 32A coincides with the value (x), the data of a latch circuit 12 is selected to the terminal 14. Since the image signal relating to the output generated from the cell 32A before one clock is latched to the circuit 12, the output of the abnormal photoelectric conversion cell 32A is replaced by the output of a normal photoelectric conversion cell.
