Title: Solenoid valve
Inventor: ASHIKAGA TADATOSHI
IPC: F16K31/06
Filed: 1988-08-27
Abstract: PURPOSE:To reduce the noise and increase the life of a product by making the polarity of a surface facing a movable body of a permanent magnet to be the same of the polarity produced at the outer circumference of the movable body when a coil is energized, and applying a magnetic flux led from the coil to the movable body in the action direction of a valve. CONSTITUTION:When a coil 2 is energized, a produced magnetic flux goes from a movable body 22 to a magnetic member 12 for leading a magnetic flux to be led to a housing 1, forming a closed loop. When the coil 2 is not energized, therefore, the movable body 22 is sucked and held by a permanent magnet 19, and if the coil 2 is energized, the movable 22 moves rolling in a cylindrical body 11. At this time, the permanent magnet 19 acts against the movable body, and a valve body 20 provided in the movable body 22 is held at a desired position to be opened or closed by motion of the movable body. The movable body 22 moving in the magnetic flux thus rolls in the cylindrical body 11, thereby production of collision sound is eliminated, and the life of a product is increased.

Title: Scaffold device in pressure vessel of pressurized fluidized bed boiler
Inventor: KIKUCHI KATSUMI
IPC: F22B37/02
Filed: 1995-08-21
Abstract: PROBLEM TO BE SOLVED: To avoid the hampering of the performance of a pressurized fluidized bed by a method wherein a guide metal ware mounted on an upper mirror of a pressure vessel and a hoisting metal ware mounted on the other end side of an erectable scaffold are arranged and a chain is coupled to the hoisting metal extending to a fixed scaffold via the guide meal ware to lower the height of the pressure vessel. SOLUTION: When another scaffold is needed in addition to a fixed scaffold 3 to mount a hoisting hook on an upper mirror 2 in the maintenance of devices or the like, a chain 8 is adjusted so that an erectable scaffold 4 is leveled to reach the position as indicated by the solid line and used as a sort of the fixed scaffold 3. When the use of the erectable scaffold 4 becomes unnecessary or the scaffold poses an obstacle to the movement of the devices or the like, a hoisting metal 6 is hoisted by the chain 8 to turn the erectable scaffold 4 as indicated by the two-dot chain line according to the arrow 10 centering around a link metal 5 so that the parts of the scaffold are raised from the center thereof to be erected and then, the free end of the chain 8 is fixed on the fixed scaffold 3.  This enables the lowering of the height of the pressure vessel 1 thereby avoiding the hampering of the performance of a pressurized fluidized bed.

IPC: H01L21/66
Filed: 1988-08-26
Abstract: PURPOSE:To find an accurate impurity activation rate even in the case of a low dose by a method wherein the effect of a surface depletion layer is removed from a sheet carrier concentration calculated by Hall measurement. CONSTITUTION:A plurality of pieces of semiconductor samples, whose impurity activation rates ought to become identical with one another and whose doses Nd only of impurity are different from one another, are prepared.

Title: Small sized fresh water generator
Inventor: OGINO MASAO
IPC: C02F1/46
Filed: 1981-12-23
Abstract: PURPOSE:To reduce the size of a fresh water generator by immersing a semipermeable membrane having the nature to be charged to either of plus or minus into raw water, charging the raw water to minus or plus of a reversed polarity, conducting electricity thereto, allowing impurities to remain on the raw water side of the semipermeable membrane and allowing pure water to permeate through the membrance. CONSTITUTION:Pure water is poured into an inside cell 1 provided with a cathode 4 to the extent that the cathode 4 is wetted with said water and the spacing between an outside cell having an anode 2 and the cell 1 is filled with the raw water. The wall of the cell 1 is a selective permeable wall and the pure water and the raw water in contact with said wall are charged to puls. When electricity is conducted from an electric power source part 6 to the anode 2 and the cathode 4, the raw water charged to plus passes through the wall of the inside cell and is conducted to the inside of the cell 1. In this time the transfer of the impurities in the raw water into the cell 1 is prevented by the selective permeable wall of the cell 1 and only the pure water is stored in the cell 1. The stored pure water is removed through a pipe 8.

Title: Method and device for grinding brittle material
Inventor: OSUMI MASAO
IPC: B02C4/08
Filed: 1990-08-10
Abstract: PURPOSE:To improve grinding efficiency and to eliminate the need for a disintegrator and to grind the brittle material such as cement clinker by alternately forming an annular recessed part and an annularly projecting part to a pair of respective rolls and forming the oblique faces to the respective annular recessed part and forming the oblique faces whose width is made narrower as reaching the tip parts to the respective annularly projecting parts. CONSTITUTION:Both rolls 1, 2 are mutually rotated to the inside at the same velocity and cement clinkers 8, 9, 10 are supplied thereto. The clinker 8 introduced into the vicinity of the bottom part 6 of a recessed part 4 is compressed in the direction A7 by the tip part 7 and ground. The clinker 8 receives shearing force by difference of the circumferential speed together therewith and becomes fine powder. Further in this case, since the oblique face 11 of a projecting part 5 is tilted, compression force is made slightly weaker than the tip part 7. Therefor this clinker is partially moved in the direction A8. Deviation due to shearing is added to this partial movement. The ground brittle material is discharged from this roll device as fine powder without becoming a flake shape. Thereby the brittle material is pulverized at high efficiency.

Abstract: PURPOSE:To print a cut mark display at a high speed by printing the cut mark display in dots on the reverse surface of continuous printing paper with higher pressure or density than an information display. CONSTITUTION:An image of a negative film 22 is exposed to the continuous printing paper 10 drawn out of a roll part 10A by a printing part 10 and the paper is sent to a printing part 10. The printing device 24 prints the information display of the exposed image in dots on the reverse surface of the printing paper 10 and also prints a cut mark in dots with higher pressure than said dot print. Then, the printing paper 10 is sent from a development part 14 to a cutting part 16, the cut mark is detected by a sensor 36, and a cutting machine 42 is driven to cut the photosensitive paper near the cut mark to small width. Thus, the conventional punch for cut mark punching is not used, so the cut mark is displayed at a high speed.

CONSTITUTION:A roll has grind mark skewed to the peripheral direction of a roll 1, further, the skew direction is symmetrical about a boundary of roll center part. The roll is produced by the grinding method that the rotating axis of a rotating disc grinding stone is shifted at right angle to a roll axis 2, while a part of the periphery of grinding face of grinding stone is brought into contact with roll surface and traversed relatively in the axial direction, the roll is rotated, the skew angle theta (>=20 deg.) is adjusted to satisfy the prescribed condition. The angle theta is calculated from a rotating speed of grinding stone, radius of grinding stone, offset of grinding stone, relative traversing speed in roll axis direction and rotating speed of roll. This roll is used for cold rolling as a large diameter work roll to produce a metal sheet. By this method, a metal sheet of high gloss is efficiently produced without deviation and torsion of rolled stock.

IPC: H04N1/413
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To compress data describing an image by using an optimum data compressing method by discriminating an image type by using the mean transition number of binary values in a data segment and a cumulative pixel number obtained from a transition array. SOLUTION: In a RAM 18, an image classifying procedure 22 can select one of compressing procedures in a ROM 20 which is most suitable to a binary pixel image 24. Once the image 24 is compressed, the area of the image in the RAM 18 is released so that it can be used for a next image part, and the compressed image is stored in the area 26 of the RAM 18. When a print engine 12 gets ready to receive image data for print, an uncompressing procedure is read out of the ROM 20 to re-form a binary pixel image, and the image is transferred to an image buffer relating to the engine 12. Then the engine 12 outputs a hard copy of the binary image.
