Title: Apparatus for preventing gas leak accident
Inventor: MATSUMOTO HISAO
IPC: G08B21/16
Filed: 1990-01-11
Abstract: PURPOSE:To prevent gas leak accidents due to unexpected gas discharge by operatively opening and closing a gas path only in the normal operation of a gas leak detector and the normal condition of a gas path opening-closing device. CONSTITUTION:An IN-2 on a line No.5 column in gas detection is closed according to an alarm signal to supply current to an X2, close an X2a1 on line No.6 and an X2a2 on line No.7 column and open an X2b1 on line No.3 column and X2b2 on line No.8 column. Thus, the X2a1 forms the self-holding circuit for an X2, and the opening of the X2b1 on the line No.3 stops the operation of the X1 and opens the X1a2 the line No.4 so that the power supply to a gas path shutting-off electromagnetic valve connected with an OUT terminal is stopped to shut off the gas path. At the same time, a circuit closed by the X2a2 on the line No.7 column lights a lamp EL for alarm display. A gas path shutting-off condition and alarm display after the reception of the alarm are held as they are as long as no abnormality is found in the power supply of a power supply bus RT. Such condition continues even if a compartment which had gas leak has returned to the normal condition, and the restart after the confirmation of safety requires the operation of a PBS on line No.2, so that the gas leak accident can be prevented.

Title: Printed matter checkup method
Inventor: SHIMADA HITOAKI
IPC: G06T7/00
Filed: 1988-01-14
Abstract: PURPOSE:To simplify the operation by an operator by automatically recognizing the size of printing paper to be checked, setting a checking area according to the size and starting the checkup. CONSTITUTION:A scan start line (a) is preset by means of a timing pulse of a rotary encoder so that paper feed is started. Consequently a paper catching side can recognize the paper feed. A detection signal differs considerably in terms of gradation detection; that is, approx imately 20 gradations of gray scale on the surface of an impression cylinder 3 and approx imately 200 gradations on the blank part 4 of printed matter. Therefore, each single line of data in a scan line is taken out of an image memory, and a boundary between the impression cylinder and the blank part is detected from both the start side of the single line and the end side. While the right and left ends of each line are detected, a signal from the blank part ceases to be detected, and subsequently, pixels on the right and left ends can no longer be determined. This line can be regarded as the end of the feed-in side.

Title: Method for activating decayed japanese lacquer
Inventor: NAGASE KISUKE
IPC: C09F1/02
Filed: 1990-01-11
Abstract: PURPOSE:To activate or regenerate decayed Japanese lacquer having no dryability at ordinary temperature by applying a shear force to a decayed Japanese lacquer solution substantially in this film form. CONSTITUTION:A decayed Japanese lacquer is formed into substantially a thin film. A thinner film is more desirable, and the thickness of the film is usually 1,000mu or less, preferably 500mu or less. A shear force is actively applied to the substantially tin film. An example of a processing device is a thin-film processing device of wiper type. As the raw material decayed Japanese lacquer, those containing at least 10wt.% water are preferably used; those containing less than 10wt.% water are not desirable since they cannot provide sufficient film properties, such as gloss and transparency. Any temperature above ordinary temperature is suitable. In most cases, heating is not necessary because of heat buildup due to friction. By the above-mentioned technique, a decayed Japanese lacquer, which could not be used alone and could only by utilized as an extender in the prior art because of lacking in cold-setting properties, can be made sufficiently utilizable as a Japanese lacquer coating material even when used alone.
