Title: Grinding method for core block
Inventor: MUKAIDE NORIAKI
IPC: G11B5/127
Filed: 1988-09-27
Abstract: PURPOSE:To prevent the shortening of the useful time of a grindstone due to the reduction in the dimensional accuracy of a gap depth according to the use and the abrasive grain falling, by setting the depth of cut by a cup like grinding grindstone larger than the sum of the length of the core block along the grinding direction and the width dimension of the abrasive grain surface along the radial direction of the cup like grinding grindstone. CONSTITUTION:The depth of cut S of a core block 13 by a cup like grinding grindstone 17 is set larger than the sum of the length W0 of the core block 13 along the grinding direction and the width W1 of the abrasive grain face 17d along the radial direction of the cup like grinding grindstone 17. As a result, the rear end edge 17b of an abrasive grain structure 17a is passed through the whole area of the lower end face 14 of the core block 13, even if uneven wear 17c is generated at the front edge part of the abrasive grain structure 17a, and the lower end face 14 is ground at a fixed depth of cut. Then after the wear of this abrasive grain structure 17a reaching a specified control limit value, the pivotally supporting position of the cup like grinding grindstone 17 is moved by specified amount in the direction orthogonal with the lower end face 14 of the core block 13. Thus the grinding conditions of the grinding grindstone 17 are recovered.

Abstract: PURPOSE:To obtain a head excellent in a reproducing efficiency and suitable to a high density magnetic recording by having a magnetic gap formed by the laminated layer of a magnetic thin film and a non-magnetic thin film at one side core half body. CONSTITUTION:The head is formed by non-magnetic substrates 1 and 6, a front magnetic core 2, a magnetic gap 3, a coil 4, terminals 4a and 4b and a rear magnetic core 5. By sticking together with a glass or a resin so that joining parts 5a and 5b of the rear magnetic core 5 can be coincident to joining parts 2a and 2b of the front magnetic core 2 respectively, a thin film magnetic head is manufactured. In short, to a first substrate 6, the rear magnetic core 5 is formed, the front magnetic core 2 and the coil 4 including the magnetic gap 3 laminated and formed at a second substrate 1 are formed, both substrates are stuck together so as to coincide magnetic core joining parts 5a and 5b and 2a and 2b, thus, a thin film magnetic head considering the shortening of the magnetic path length is obtained, further, a manufacturing process per substrate can be decreased, and therefore, the number of the days of the manufacturing of the thin film magnetic head can be made into about 10 days.

Title: Electronic component mounting substrate
Inventor: NAKADA JUNJI
IPC: H05K1/11
Filed: 1993-09-30
Abstract: PURPOSE:To prevent the occurrence of insufficient mounting caused by molten solder by forming a metallic pattern around mounted electronic components. CONSTITUTION:A metallic pattern 12 is formed on a mounting substrate 11. The pattern 12 is formed in the form of a rectangular frame on the surface 13 of the substrate 11.

Abstract: PURPOSE: To improve the leak detection of a radioactive waste housing and increase the cooling efficiency in spontaneous air-cooling by providing a monitoring system to detect the leak of radioactive substances. CONSTITUTION: Housing pipes 20 are erectly placed inside a cell chamber 1 to house radioactive waste housings P which are piled vertically, and is controlled by a supporting structure 6.

Title: Microwave discharge light source device
Inventor: NATORI SHIGERU
IPC: H01J65/04
Filed: 1985-10-31
Abstract: PURPOSE:To obtain a microwave discharge light source device which can increase the radiating quantity of light to the outside by arranging a microwave bandpass filter for passing the basic wave component of microwave energy while suppressing/attenuating other higher harmonic components in a waveguide. CONSTITUTION:Microwave energy oscillated from a magnetron 1 contains main basic wave component in a microwave circuit system and unnecessary higher harmonic components having integer times of frequency of the basic wave. When passing through a microwave bandpass filter 15 and a waveguide, the higher harmonic component microwave energy is suppressed and attenuated and only the basic wave component is led to a microwave resonant cavity 5. Consequently, the opening rates and the arranging gaps of the first and the second metal mesh boards 7, 8 are not required to match with the higher harmonic components of the microwave for the purpose to prevent leakage of the microwave energy but can be set to the basic wave component resulting in increase of the opening rate and the radiating quantity of light to the outside.

Abstract: PURPOSE:To continuously produce a colored stainless steel strip with one liquid and one stage by subjecting the stainless steel strip to pretreatments such as degreasing, pickling and cleaning then passing the strip to an AC current electrolytic cell for the purpose of coloring and film hardening. CONSTITUTION:The stainless steel strip from an un-coiler 2 is passed through an alkali degreasing tank 3, a hot rinsing tank 4, a pickling tank 5 and a hot rinsing tank 6 by which the pretreatment for cleaning is executed. The strip is then subjected to an electrolytic treatment by AC current between counter pole plates 9 in the electrolytic cell 8 contg. an electrolyte contg. CrO3 and H2SO4 and is thereby colored. The stainless steel strip 1 is subjected to the color tone measurement by the electrolyte on the strip with a color discrimination sensor 11 provided at the outlet of the cell 8 and the resulted data is inputted to a computer 12 for controlling electrolysis conditions. The electrolysis conditions [current density (i) of the anode electrolysis and cathode electrolysis, electrolysis time (t), number N of repeating of electrolysis, etc.] are adjusted and the coloring treatment is controlled when the data exceeds the preset threshold of the color tones. The steel strip is thus finished to the surface having the intended color tones.

Filed: 1986-10-15
Abstract: PURPOSE:To recognize properly the irradiation field by taking an optional point in which a differentiation value in differentiation pictures formed by picture information is maximum or a prescribed value or over as the 1st notice point and seeking a position where the differentiation value has a prescribed value or over from the surrounding of the 1st notice point and using the position as the 2nd notice point so that the inside of a closed curve formed by tying the notice points is recognized as the irradiation field. CONSTITUTION:The differentiation value of a picture data at a position where an irradiation field profile exists has a larger quantization level than that of a differentiation value of a picture data at other positions in general. Then positions where the irradiation field profile in the differentiation picture exists based thereupon is sought one after another so as to detect the irradiation field profile. At first, the differentiation picture is scanned and an optional position where the differentiation value is maximum or a prescribed value or over is found out and it is used as the 1st notice point. Then, a position where the differentiation value is a prescribed value or over among adjacent positions to the 1st notice point is sought and it is used as the 2nd notice point and new notice points are sought one after another. When new notice points are sought, they are tied together to form a closed curve. Then the inside of the curve is recognized as the irradiation field.
