Title: Warning device and state judgement method
Inventor: ITO TOSHIAKI
IPC: G08B25/00
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous judgment that a system is normally restord even if a power cut or fault occurs during the detection of abnormality by transmitting a normal signal when a value showing normality continues for prescribed time when the output voltage of an existed voltage detector changes from a value showing abnormality to the value showing normality. SOLUTION: When a change is judged to exist in the output voltage E of an existed voltage output part and it is DC 12 V (P2), the transmission of a gas leaking signal is instructed (P4). It is judged whether output voltage E is DC 12 V, 6 V or 0 V in such a state. When it is judged to be 6 V, (P5), a timer is started (P6). I is judged whether output voltage E is DC 6 V or not (P7). It is judged whether the continuation time (t) of DC 6 V in the timer exceeds prescribed time Th=5 seconds or not (P8). When t>=Th, the transmission instruction of the normal signal is outputted and the timer is cleared (P9). When output voltage E is judged to be 0 V (P5), the transmission instruction of unit abnormality is transmitted (P10).

Inventor: ITOU HITOMI
IPC: C25F3/16
Filed: 1982-08-17
Abstract: PURPOSE:To obtain a surface to be subjected for observation by a transmission electronic microscope by such an arrangement wherein a cover which is hard to be dissolved and permeated for grinding conditions is caused to tightly contact with a desired surface of thin plate when the thin plate is to be ground by electrolytic grinding or chemical grinding in which the plate is to be immersed in a grinding liquid, and then the plate is ground. CONSTITUTION:A cover 7 is caused to closely contact with the object surface 5 of a test specimen 1 which is an anode, and the test specimen is immersed in an electrolytic grinding liquid 3, and a cathode 2 is installed at the side opposite to the object surface 3 and electrolytic grinding is performed. As a cover, e.g., a piece of Scotch tape or insulation vinyl tape may be used. By electrolytic grinding, the central portion of the test specimen 1 gradually becomes thinner and a hole is eventually made, but the object surface 5 is not ground as it is prevented from contacting with the electrolytic grinding liquid. Upon completion of electrolytic grinding, the cover 7 is peeled off or dissolved by a solvent, and by this procedure, a test specimen having a portion which corresponds to the object surface and is not ground and still has a desired thickness can be made.

Title: Manufacturing method of aperture type fluorescent lamp
Inventor: URATA YOSHIZOU
IPC: H01J9/22
Filed: 1981-09-10
Abstract: PURPOSE:To improve work efficiency remarkably and reduce cost by laminating and forming the first and second coats containing different binders and forming an aperture section by exfoliation. CONSTITUTION:Since the first coat (reflection coat) 2 and the second coat (phosphor coat) 3 are formed over the entire inner surface of a glass bulb 1 by properly making the first and second coating liquids flow from the upper opening section of the vertical glass bulb 1 respectively, the boundary between the reflection coat and second coating liquid need not be matched by visual inspection as before. For this reason, the coating work of the coating liquid can be performed efficiently. Besides, since the second coating liquid uses a solvent that never dissolves the binder of the first coating liquid, the second coat 3 can be formed on the first coat without baking once the first coat 2 has been formed on the inner surface of the glass bulb 1. As a result, the number of baking can be reduced by half and workability can be improved.

IPC: G06F3/00
Filed: 1984-07-11
Abstract: PURPOSE:To enable all stations to share the same characters simultaneously and automatically by transmitting characters to an optional work station together with the identification numbers of the transmitting and receiving stations and the transmission end signal. CONSTITUTION:When characteristics are transmitted to other stations from work stations 1 and 2, only the codes are sent if these characters belong to a basic part. While both codes and character patterns are transmitted if those characters belong to an own register part. Then the identification number of the station at the reception side is registered and transferred. In a reception mode the received information is displayed at a CRT20 as long as the information contains the codes only. While the characters are included into the basic part and then delivered to the CRT20 in case these characters are already registered to another station register part of a memory 21 and contain a transmission end message. Then only the processing of the CRT20 is carried out in case the transmission end message is not given to all stations. These procedures are repeated for execution of transmission and reception.
