Title: Improvement of storage stability of phenolic resin
Inventor: MIWA AKITSUGU
IPC: C08G8/00
Filed: 1983-10-31
Abstract: PURPOSE:To improve the storage stability of a tung oil-modified phenolic resin used in printed circuit laminated boards or the like by preventing its viscosity loss, etc., by diluting the resin with a mixture of an alcohol solvent and a nonalcohol solvent in storing the resin. CONSTITUTION:A tung oil-modified phenolic resin is produced by reacting tung oil with phenol in the presence of an acidic catalyst and after neutralization and the addition of formalin and a basic catalyst, subjecting the product to a resol- forming reaction. When storing this resin, it is diluted with a mixture of an alcohol solvent (e.g., methanol or ethanol) and a nonalcohol solvent (e.g., toluene or chloroform) in such an amount that the alcohol solvent is 2-10wt% based on the resin. In this way, the loss of viscosity and increase in a gelation time, etc., during storage can be prevented.

IPC: B21B45/06
Filed: 1993-06-28
Abstract: PURPOSE:To enable descaling without the lowering of yield and causing incom pletely descaled part by providing plural electrodes in the advancing direction of a material to be treated, measuring the descaled area in a prestage by image analysis and calculating the amount of power to be fed in the poststage based on the result. CONSTITUTION:Descaling ability by a vacuum arc is generally proportioned to a current value fed to the electrodes 14. Then, an image analyzing/arithmetic unit 17-1 with which a descaled part and scale remaining part are classified by the difference in brightness on the surface and that area ratio is measured and calculated is installed among plural electrodes 14 and feeding power to the electrodes in the poststage is calculated based on the area ratio in the prestage and fed. It is not necessary to install the image analyzer 17-1 on all electrodes and it may be installed in accordance with plural electrodes 14. And fed power in the prestage is corrected to a proper value based on the measured area ratio. In this way, the excellent descaling entirely without the lowering of yield due to excessive electric discharge and the generation of the incompletely descaled part due to shortage of fed power is executed.

Filed: 1985-09-19
Abstract: PURPOSE:To prevent erroneous operation by power supply variation by providing a reverse charging preventive mechanism to a main capacitor. CONSTITUTION:In an electronic equipment in which power from a generator 1 is used as a power supply for a main circuit 11 in a system, a main capacitor for a large-capacity charge storage member 5 and an auxiliary capacitor for an auxiliary charge storage member 9 are employed, and these capacitors 5, 9 are boosted 7 and charged.

Title: Servo circuit for optical disk device
Inventor: NAKAJIMA YOSHIKI
IPC: G11B7/095
Filed: 1990-08-04
Abstract: PURPOSE:To prevent out-of-servo by selecting the output of a peak detection circuit or a low-pass filter relating to the light reflectance of an optical disk or the kind of the optical disk, and performing a servo operation by selected output. CONSTITUTION:When metallic powder with high light reflectance exists on a track while tracking servo is performed, the levels of the output (alpha) and (beta) of a bi-sected optical detector 9 are increased, then, is decreased immediately after that. The cycle(pulse time width) of output (alpha) and (beta) can be obtained in short pulse shape, for example, of several microseconds. The cycle is equivalent to several MHz when it is converted to a frequency. When the output (alpha) and (beta) are inputted to the low-pass filters LPF1, LPF2 whose cutoff frequencies are selected at around 100kHz, the passage of a high frequency can be blocked. Thereby, a high frequency component is eliminated from the output signals of the filters LPF1, LPF2, and whose level change can be suppressed, and no out-of-servo occurs.

Title: Magnetic recording and reproducing head
Inventor: SAKAI KAZUO
IPC: G11B5/187
Filed: 1983-11-07
Abstract: PURPOSE:To wear down the top of a magnetic head uniformly and to perform stable recording and reproduction easily by decreasing the width of the area where the magnetic hed comes into sliding contact with a magnetic tape gradually from a magnetic gap part as a center. CONSTITUTION:The magnetic head M consists of an I-shaped core 1 and a C-shaped core 2 and both cores 1 and 2 form the magnetic gap G. Bonding parts 3 made of glass material are formed at both sides the magnetic gap G. The witdh Wc of the head M near the gap G is set larger than the width We of edge parts 4. Consequently, tape contacting area near the gap G increases and contact pressure is decreased. Therefore, the amount of abrasion near the gap G becomes nearly equal to that of the edge parts 4 and the stable recording and reproduction are performed easily.

Title: Character processor
Inventor: MOMOTAKE TACHIHIRO
IPC: G06F17/21
Filed: 1989-08-09
Abstract: PURPOSE:To easily change a sentence, which includes Chinese characters (KANJI) in abnormal use, to a sentence only with KANJI in common use by retrieving only the KANJI in abnormal use from the sentence including the KANJI in abnormal use, which is the KANJI excepting for the KANJI in common use, and reading out more than one candidate for the KANJI in common use corresponding to the KANJI in abnormal use based on the retrieved KANJI in abnormal use. CONSTITUTION:When the sentence including the KANJI in abnormal use is read out from a sentence storing means 2, the sentence is stored in a temporary storing means 4 and displayed in a display means 5. In such a state, when the retrieval is indicated from an input means 1, only the KANJI in abnormal use is retrieved from the sentence stored in the temporary storing means 4 and transferred to a KANJI in common use candidate reading means 8. Further, by referring a KANJI in common use candidate dictionary memory 6, the KANJI in common use candidate reading means 8 reads out more than one candidate for the KANJI in common use corresponding to the retrieved KANJI in abnormal use and displays the candidate in the display means 5. In such a state, when an input determining indication is inputted, the selected KANJI in common use is replaced with the retrieved KANJI in abnormal use and stored in the sentence storing means 2. Thus, the sentence with the KANJI in abnormal use easily is corrected to the sentence only with the KANJI in common use.

Title: Image processor
Inventor: GO MASARU
IPC: G01B11/24
Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To maintain the recognition accuracy of an object even in the case that the image quality of input images is degraded by the attenuation of image signals. SOLUTION: To an A/D conversion circuit 6, the image signals are inputted from a camera installed in a far parking area through a cable. An FFT circuit 11 fast Fourier transforms image data for the respective rows of digital images and a filtering part 12 multiplies the reciprocal of the attenuation function of the cable with the intensity of respective frequency components and calculates component intensity before the attenuation. An inverse FFT circuit 13 inversely fast Fourier transforms the calculated result, generates restored images provided with a feature equivalent to the one at the point of time of generating the image signals and inputs them to a recognition processing part 9. In the recognition processing part 9, an edge on the restored image is extracted and a vehicle on the image is detected.

Title: Manufacture of semiconductor device
Inventor: TAKUBI ATSUSHI
IPC: H01L21/768
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of constituting a wiring layer to be connected in a two-layer structure by exposing an interlayer insulating film in a depression by etching back a photoresist after forming the depression in the photoresist and forming a contact hole by etching the interlayer insulating film. SOLUTION: A positive photoresist 7 is applied to the entire surface of an interlayer insulting film 5 to a thickness of about 1.2μm and the photoresist 7 is entirely exposed. At the time of exposing the photoresist 7, the exposure is set at a lower value, for example, about 60-99% of the exposure at which the photoresist 7 is completely exposed. When the exposure is set in such a way, halation occurs at the central part of the insulating film 5 due to the recessed surface of a depression 6 and only the exposure at the central part becomes larger than the exposure at which the photoresist 7 is completely exposed. Then a depression 8 is formed on the photoresist 7 by developing the photoresist 7.  Moreover, a contact hole 9 is formed in a self-aligning way between wires of second wiring 2 by subjecting the insulating film 5 to anisotropic dry etching by using the photoresist 7 as a mask.
