Title: Magnetic arc drive circuit breaker
Inventor: KANEMAN NAOHIRO
IPC: H01H33/20
Filed: 1994-04-07
Abstract: PURPOSE:To improve arc drive force, and improve arc-extinguishing performance of a circuit breaker by strengthening a magnetic field on the inner side of a coil in the circuit breaker provided with a butt contact using a magnetic arc drive effect. CONSTITUTION:In a butt contact type circuit breaker, arc generated between a fixed contact 1 and a movable butt contact 3 at the time of breaking by a circuit breaker is extinguished by giving drive force by a magnetic field phigenerated by a coil 2. Part or all of the fixed contact 1 is formed of a ferromagnetic body 9 of iron, for example. Because the ferromagnetic body 9 is disposed at a center part of the coil 2, the magnetic field phi becomes strong at the center part of the coil 2. thereby arc drive force can be improved.

IPC: H05B3/14
Filed: 1978-06-08
Abstract: PURPOSE: For preventing the fall of heat resisting insulating powder and the eccentrical shift of terminal bars, to temporarily seal the end openings of a metallic pipe by filling thermally expanding inorganic material therein and making thermal expansion thereof.  
     CONSTITUTION: This sheathed heater is made through the process consisting of inserting in a metallic pipe 1 a heating wire having terminal bars 2 on the both ends and filling heat resisting electrical insulation material 3 between said heating wire and metallic pipe 1. A thermally expanding inorganic material 4 such as vermiculite for example is filled in the end openings of said metallic pipe 1 and heated with a gas burner for example to expand for temporary sealing. This is followed by rooling, bending and post-treating processes for completing said sheathed heater. Thereby, temporary fastening is possible without detaching said terminal bars 2 from a fastening jig. Thus, the eccentrical shift of said terminal bars 2 can be prevented in rolling process and no pressure insertion is required in temporary fastening process so that said terminal bars 2 do not enter said insulating powder 3.

IPC: G06F1/30
Filed: 1988-03-24
Abstract: PURPOSE:To reserve the storing contents of a non-volatile memory without fail by transferring the storing contents of a volatile memory to the non-volatile memory when the residual capacity of a battery for back-up becomes under a prescribed reference level. CONSTITUTION:The residual capacity of a battery 2 for back-up is estimated by the counted value of a counting means 72 and when this estimated residual capacity is over the prescribed level, the storing contents of a volatile memory 3 (IC memory) are reserved as they are by back-up power feeding due to the battery 2.

Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To obtain a projector capable of easily achieving high contrast by compensating a phase difference between normal light and abnormal light caused in a spatial optical modulator on an optical path for optical modulation.

Thus, leakage light in the off-state of the projector 100 is reduced and the high contrast is obtained. Since temperature characteristic concerning optical modulation is nearly coincident between the cell 20 and the modulator 22, the high contrast is maintained even when the operation temperature of the cell 20 and the modulator 22 is changed.

Title: Method for removing quantization error in character generation with outline font by element
Inventor: ITO AKIRA
IPC: G09G5/26
Filed: 1989-03-24
Abstract: PURPOSE:To constitute attractive characters by providing character codes with correction information, outputting corrected elements only for the characters having the correction information, and composing the characters according to the corrected elements and then painting out the characters inside their contours. CONSTITUTION:When an outline font with low resolution is generated automatically from an outline font of high quality, lines or dots continue in a character whose elements are complicated and the character becomes inattractive. This character is given correction information together with its character code in advance. Therefore, when a character like this is inputted on a keyboard 1, a correction information storage means 13 detects this correction information. Then coordinate point information of one element of a corrected character stored previously in a correction information storage means 13 is outputted in order according to the correction information and character code. A character is composed of elements which need not be corrected through a normal route. Consequently, the attractive character is obtained.

Abstract: PURPOSE:To perform a low frequency conversion with the same frequency as a local frequency used for a color system and to improve a frequency characteristic by separating luminance signal components at the high frequency side by means of a comb-shaped filter. CONSTITUTION:A video signal is inputted to a BPF1, HPF5 and an LPF9 of a magnetic recorder, and color video signal components passing through the BPF1 are converted into low-frequency by means of a convertor 4. A luminance signal system is separated into two systems by a comb-shaped filter 2 and a subconvertor 3. Furthermore, the low-frequency side luminance signal whose color components are removed by the LPF9 is frequency-modulated in a modulator 10. The video signal through the HPF5 is added to a comb-shaped filter 6, converted into low-frequency in a convertor 7 by the local frequency from the subconvertor 4 after its color components are removed, and finally overlapped with a low- frequency conversion color signal by a mixer 8. The signal obtained in such a way is overlapped with the low frequency luminance signal which is frequency- modulated by a mixer 11, and made into a recording signal.
