Patent JP-S5880243-A (JP)
Title: Microwave tube
Inventor: MITSUYASU SATORU
IPC: H01J23/087
Filed: 1981-11-06
Abstract: PURPOSE:To improve the beam stability and the reliability, by making the width of a permanent magnet at the position near to an electron gun in a microwave tube having a periodic field device combined with pole chips and permanent magnets alternatively wider than those of other permanent magnets. CONSTITUTION:The larger the ratio lambdap/L between the plasma wave length lambdap and the period L of a periodic field device, the more the beam is stable. Here L is the period, T is the thickness of a permanent magnet while t is the thickness of a magnetic pole chip 2 and there is the relation L=2(T+t). Consequently assuming the thickness of the first permanent magnet 5 is T1, it is formed such that T1 will be thicker than the following permanent magnet 3. Consequently the field on the cathode is strengthened. As a result the stability of the beam is improved resulting in a highly reliable microwave tube.

Inventor: TAKEMORI TAMIKI
IPC: G01B11/16
Filed: 1988-07-18
Abstract: PURPOSE:To achieve a higher measuring accuracy by renewing a reference pattern of a mutual correlationship function when an maximal value of the mutual correlationship function falls below a preset value to minimize displacement measuring errors of an object when a change in a speckle pattern is limited.

IPC: H04N17/04
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To measure the luminance characteristic of a CRT with high accuracy at a high speed. SOLUTION: A data fetch control section 2 of this luminance characteristic measurement instrument changes the raster size to display a test pattern, consisting of a plurality of longitudinal or lateral stripes generated by a signal generator 4 onto a color CRT 6, in a way such that relative positions of phosphors in each stripe differs from each other. The image of this test pattern is picked up by a CCD camera 3 and the data fetch control section 2 fetches the picked-up image. The emission position and the luminance level of each stripe of the emission phosphor are calculated from the picked-up image and the luminance distribution of the test pattern in units of stripes (luminescent-non- luminescent-luminescent parts) is calculated by rearranging the luminance levels, based on the light emission position and a display device 52 displays the result of calculation.

Title: Electric servo motor
Inventor: YONETOMI TSUGUYASU
IPC: H02K7/08
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To make starting torque small and constant and make a zero point of a linear motion of a ball screw also constant by using angular ball bearings as for bearings for receiving thrust load of a driving shaft which is driven by a rotary motion of the motor and makes a linear motion. SOLUTION: When a nut 18 is tightened, an inner ring of an angular ball bearing 20b is just tightened from right and left and the tightening force does not reach a ball of the bearing, and therefore it does happen that the rotation of the bearing becomes tight. The angular ball bearings 20a, 20b have a taper on an inner side of an outer ring and can receive thrust load as well as radial load. In an electric servo motor of such a structure, starting torque is severalty that of the conventional type, thereby reducing the size of a plumb to be used when a power supply of the motor is lost or of an external closing device constituted of springs. Furthermore, as starting torque is constant in a motor of such a structure, the bearings can be designed and manufactured in parallel with the design and manufacture of the electric servo motor and therefore the time for delivery can be shortened.

Title: Water cleaning device
Inventor: FUNAYAMA ICHIRO
IPC: C02F1/50
Filed: 1987-07-20
Abstract: PURPOSE:To prevent the red water phenomenon occurring in corrosion product such as iron hydroxide by passing raw water such as tap water first through iron-removing filter media, then through silvered active carbon and passing this water through ultrafilter membranes. CONSTITUTION:A water cleaning device 10 has a pair of cylindrical bodies 1, 2. The iron-removing filter media 13 and the silvered active carbon 14 are packed into one cylindrical body 1 installed on the upper stream side of the water treatment system. The ultrafilter membrane 36 are packed into the other cylindrical body 2 installed on the down stream side of the water treatment system. The treated water is, therefore, completely removed of iron and iron ions by the filter media 13 and is then sterilized of chlorine smell, smells, org. materials and more particularly, bacteria, by which the water is cleaned. Finally, the water is passed through the membranes 36, by which the removed bacteria, etc., are completely filtered out. Since the water is already substantially sterilized by the active carbon 14 at this time, the adhesion of the bacteria to the membranes 36 and the propagation thereon are lessened.

Title: Blowing device of wall surface release diagnosis machine
Inventor: OI HISASHI
IPC: G01N29/12
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To obtain a blowing sound for accurately judging the release of a wall surface due to a frequency analysis after the wall surface is blown and then a hammer immediately leaves the wall surface. SOLUTION: A roller 311 of a rod 31 is pushed up while it rotates on the outer periphery surface in involute surface shape of a cam 335 that rotates in the direction of an arrow R, thus causing the rod 31 to retreat. Also, a hammer 35 is allowed to retreat along with the rod 31 via a coil spring 36 for recovery. When the rod 31 reaches a stroke rear end position, the roller 311 deviates from a maximum diameter part 335a of the cam 335 and the rod 31 and the hammer 35 speedily advance due to the extension of a coil spring 34 for blowing being compressed. The hammer 35 advances due to inertia even after the rod 31 stops and blows a wall surface W to be diagnosed. The hammer 35 leaves the wall surface W to be diagnosed due to the pull biasing force of the coil spring 36 for recovery immediately after blowing.

Title: Preparation of substance for controlling and improving skin
Inventor: SHIRAISHI TOSHIO
IPC: A61K8/00
Filed: 1981-11-09
Abstract: PURPOSE:To obtain the titled slightly yellow and transparent substance having effects on the remedy of skin disease and beautifying effect free from stimulation, by blending a solution of coicis semen pulveratum with iodine, to give a colored solution, treating the solution with enzyme so that it is faded. CONSTITUTION:Coicis semen pulveratum is gelatinized and made into a paste to give a solution, to which iodine is added to prepare a colored solution. The solution is treated with enzyme (e.g., amylase, protease) at >= about 40 deg.C and faded. Insoluble substances are filtered off from the faded solution to give a slightly yellow and transparent solution. Coicis semen pulveratum is obtained by removing pericarp and seed coat from the fruit of a chicken breast, a gramineous plant, and has been used as a medical decoction. It is not used easily for external use, and its application has been limited because of the dark brown and stimulation of iodine of its own. Both the compounds are blended and made into the solution by this method, so the above-mentioned defects are solved while providing improved medicinal effects and beautifying effects.
