Title: Liquid spreader
Inventor: IMURA KOJI
IPC: F25B33/00
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To drip liquid precisely, and to avoid that the condition of spreading becomes non-uniform as a result of clogging by juxtaposing straight pipes with fins transversely, by opening a plurality of small holes in the vertexes thereof, and by mounting a plate on them to cover them. SOLUTION: Many small holes 4 are opened at a predetermined interval in the vertex parts in the lengthwise direction of the straight pipes 1 that are juxtaposed horizontally. The diameter of the small hole 4 is made slightly small, so that the liquid can be spread uniformly from any small holes, even when a spreader is tilted during the spreading operation. In other words, since the diameter of the small hole 4 is determined in such a manner that the pressure loss at the time when the liquid is ejected from the small holes 4 becomes larger than the pressure loss of a channel 6b in which the liquid inside the straight pipe with small holes 1 flows, the liquid is spread uniformly.  The liquid that is ejected from the small holes 4 is spread to spaces 5 and 5b to decrease its flow velocity, and then it flows down slowly along the side wall of the straight pipe with small holes 1 as it is. The device operates to drip the liquid to the determined position such as a heat transfer tube 8 from the lower part of the straight pipe with small holes 1.

Title: Magnetic printer
Inventor: INOUE KUNIHIRO
IPC: G03G19/00
Filed: 1988-01-12
Abstract: PURPOSE:To obtain printing of high quality by preventing toner from attaching uselessly to a location near a latent image and enabling the toner faithful to the latent image to be attached, by a method wherein a weak electric field is applied between a magnetic drum and a developer. CONSTITUTION:A certain magnetic latent image is formed on a magnetic drum with a recording head 1. At that time, though voltage is impressed to the magnetic drum 10, there is magnetically no influence. Then, though development is performed in order to visuallize the latent heat, a toner is stirred inside a developer, and is given a positive change, and is magnetically attracted to a magnetic roller 3 in the developer. When development is performed under this state, a sharp visual image is formed. Thereafter, it is transferred to paper 6 with a transfer roller 7, and is fixed with a fixing roller 8. Thereby, printed printing quality becomes clear.

Title: Method and device for controlling superconducting coil current in nuclear fusion device
Inventor: TAKEUCHI KAZUHIRO
IPC: G21B1/00
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To reduce the loss of alternating current in the annihilation of plasma current and avoid quench by providing a mechanism to detect the spontaneous annihilation of the plasma current and an arithmetic mechanism to evaluate the loss of the alternating current and set a current target value so that a magnetic distribution can reduce the loss of the alternating current. SOLUTION: Plasma 1 are controlled by the magnetic field formed by a superconducting coil 2. The change of the magnetic field around the plasma with time is measured by a magnetic-field sensor 3 using a pickup coil and is determined as a plasma current value, a sectional form of the plasma and a magnetic field distribution after the error correction by a signal processor 4. A disruption detector 5 detects the spontaneous annihilation of the plasma current from the difference between the plasma current value and a target plasma current value set in advance, and a current- distribution arithmetic unit 6 computes a current distribution for reducing the loss of alternating current on the basis of the detection by the detector 5 and transfers the target current value to a current controller 7.  As the controller 7 controls the coil current by adjusting a voltage applied to the coil, the loss of the alternating current is curbed and the coil 2 is free from quenching.

Title: Proportional pressure control valve
Inventor: MATSUMOTO TOMOHIDE
IPC: H01F7/13
Filed: 1982-01-13
Abstract: PURPOSE:To diminish the magnetic hysteresis loss of a part with high magnetic flux density and the application of cheap magnetic material to the remaining part is made possible by a structure wherein yoke pieces having magnetic characteristics with a small hysteresis loop are provided at the parts with high magnetic flux density in the magnetic circuit of a magnetic driving unit. CONSTITUTION:When a coil 9 is energized, a magnetic flux phi, the amount of which is proportional to the amount of electricity passing across the coil 9, is generated in the magnetic circuit consisting of a yoke 8, a plunger 11 and the yoke pieces 12 and 12', resulting in producing electromagnetic force to push the plunger 11 down so as to be able to control the pressure of fluid outlet 2 side in proportion to the amount of electricity past across the coil 9. Although magnetic flux density becomes dense because of a narrow cross sectional area of magnetic path at positions A and B, at which the yoke pieces 12 and 12' and the plunger 11 stand opposite to each other respectively, no increase of magnetic hysteresis loss as compared with the case in conventional valve is resulted because of the provision of the yoke pieces 12 and 12', which are made of P,B permalloy having magnetic characteristics with a small hysteresis loop and high magnetic permeability.

Filed: 1980-01-18
Abstract: PURPOSE: To feed magazines placed in the correct direction only automatically to a feed guide by dropping magazines in disorder from on a belt with a drop lever.  
     CONSTITUTION: A drop lever 4 projects to a face whereat a magazine 8 delivered onto a projection of the drop lever 4 comes in contact with a belt 3. All magazines 8 except that whose face with a concavity 10 formed thereon is in contact with the belt 3 are hit by the drop lever 4 to drop in the direction Q indicated by arrow. However, when the magazine 8 is positioned with its concavity 10 face on the belt 3, the drop lever 4 comes into the concavity 10 without hitting the bottom of the magazine 8, therefore the magazine 8 is not dropped from on the belt 3, reaches a feed guide 7 as placed in the correct direction and is thus fed on a lever 6 in order.

Title: Method for soldering process which improves surface property through thin film sticking
Inventor: THOMAS E DINAN
IPC: H01L21/768
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To eliminate the possibility of any reactive material such as solder flowing out to, depositing to, or reacting with, the side wall of a mesa structure, by letting non-reactive material deposit to the side wall of the mesa structure, and cleaning the exposed horizontal surface of the mesa structure. SOLUTION: Non-reactive material is selectively deposited to the vertical side wall of a mesa structure by sputtering. The conditions of the sputtering are as follows: The exposed horizontal surface of the mesa structure should be cleaned so that a horizontal surface more reactive than the side wall of the mesa structure can be obtained; and the speed at which the non-reactive material is stuck to the side wall should be equal to the difference between the speed of sticking by sputtering and the speed of removal. As a result, a non-reactive thin film cannot grow on the more horizontal surface. Only a few non-reactive material is preset on the exposed horizontal surface in the equilibrium state of sputtering.

Title: Transmission type screen
Inventor: ITO AKIRA
IPC: G03B21/625
Filed: 1988-01-14
Abstract: PURPOSE:To eliminate almost all optical bad influence even in case of slight deviation of positional relations of front and rear faces by setting a line forming the sectional shape of an incidence face lens so that the condensing characteristic in the center part and that in the peripheral part are different from each other. CONSTITUTION:The condensing characteristic based on the curve, which forms the sectional shape of an incidence face lens 1, in a center part 20 and that in peripheral parts 18 and 19 are made different from each other. Concretely, the condensing characteristic in peripheral parts 18 and 19 of the incidence face lens is so set that angles of incidence on light emission faces 16 and 17 are reduced. In case of this transmission type screen, angles of incidence on parts of an emission face lens where shading and total reflection are apt to occur are smaller than normal those even if the incident position of light is changed by production error or lenticular lenses on front and rear faces are horizontally shifted from each other or the screen thickness is different from a design value. Thus, the occurrence of shading is prevented, and total reflection and return to the incidence side of the light are reduced.

Title: Monitoring method for thread package quality
Inventor: MUTSUTERU HAINTSU
IPC: B65H63/00
Filed: 1993-01-14
Abstract: PURPOSE: To monitor the compactness of thread by a method wherein a thread route is warped so as to make the end of the thread protrude when the thread is cut off and a sensing stage includes the detection of transmission of charge on the thread to sensing means provided with predetermined intervals along the warped thread route and the cut end of the thread is brought into contact with the sensing means by a centrifugal force. CONSTITUTION: The angular position of a rod 40 from a wooden pipe 26 enables accumulation of charge on the surface of a tail end T by the friction between the protruding tail end T and air surrounding a package when the protruding length of the tail end T reaches the maximum value. A spacing d is selected so as to have the tail end T brought into contact with an edge E when the tail end T passes through the rod 40 and, further, to have the tail end T brought into contact with a surface S before the contact with the edge E. The friction between the surface S and the tail end T increases accumulated charge on the tail end T further. The accumulated charge is transferred to the rod 40 while the tail end T is brought into contact with the edge E and converted into a potential by the connection of the rod 40 with a wire 44.  The change into the potential is detected by a measurement circuit and recorded as a package flaw.

Abstract: PURPOSE:To prevent deterioration of the magnetic characteristics of a magnetic circuit by joining the entire side faces of the 1st and 2nd cores opposite to the sliders to one of both sliders and at the same time using an elastic member unified with a coil bobbin to fixing with pressure a 3rd core to both 1st and 2nd cores. CONSTITUTION:The entire side faces of 1st cores 2a and 4a and 2nd cores 2b and 4b opposite to sliders 7 and 8 are joined to one of both sliders. At the same time, the back cores 15 and 16 are fixed with pressure to those cores 2a-4b via an elastic member plastics, etc., unified with coil bobbins 9 and 12. Therefore, the joined area is maximized as much as possible to one of both sliders of said 1st and 2nd cores and a high degree of joining strength is obtained. In addition, the cores 2a-4b are totally reinforced by means of the sliders 7 and 8 and furthermore no back gap is produced among those cores 2a-4b and back cores 15 and 16. Thus both cores 15 and 16 are fixed to each other with adhesion. Then the deterioration of the magnetic characteristics can be avoided for the cores.
