IPC: G11B20/12
Filed: 1995-01-24
Abstract: PURPOSE: To perform a data write processing operation to a data recorder at a high speed by improving a tape logical format. CONSTITUTION: Logical information on last data is written into a DIT as header information. The logical information is read out when a tape is loaded, and it is held in a memory. A data write request is generated when new data is to be recorded additionally with reference to data which has already been written on the tape. Then, the logical information on the last data is acquired from the memory in Step S11. Then, in Step S12, logical information is added to data to be written newly. Then, the data and the logical information are written on the tape. Thereby, it is not required to perform a processing operation to read the tape before a write operation is performed.

Title: Manufacture of lead-acid battery
Inventor: WADA YASUO
IPC: H01M2/38
Filed: 1992-02-17
Abstract: PURPOSE:To facilitate substitution between the air in a power generating element and an electrolyte by inclining a lead-acid battery having the power generating element housed in a jar, and filling the jar with the electrolyte through a liquid filling port formed on a cover. CONSTITUTION:A battery jar 1 is fitted with a cover 7 having a liquid filling port 6. The jar 1, when filled with an electrolyte 8, is kept in inclined state and the electrolyte 8 is supplied through a liquid filling nozzle 9. As a result of this liquid filling operation, the electrolyte 8 is first supplied to the lower section of an inclined battery due to gravity, and a power generating element 5 is gradually impregnated with the electrolyte 8 from the lower position of the battery in inclined state. Thus, the air in the element 5 is gradually pushed out toward the upper position of the inclined battery, and substitution between the air and the electrolyte 8 is thereby facilitated. Also, even when a filling rate is increased, compared with a conventional case, the substitution is facilitated between the air in the element 5 and the supplied electrolyte 8, thereby shortening a liquid filling time.

Title: Mobile object tracking processing method
Inventor: FUJINO YUICHI
IPC: G06T7/20
Filed: 1992-02-17
Abstract: PURPOSE:To recognize only a targeting mobile object and to facilitate the tracking of the mobile object even if another new mobile object intrudes into a rectangular area and is recognized as a closed area by changing sprirally the direction in which the presence or absence of a label number is scanned. CONSTITUTION:When the labeling processing is carried out in a rectangular area, the direction in which the presence or absence of a label number is scanned is spirally changed with the centroid point set in the preceding frame defined as a starting point. That is, a mobile object area is segmented in a rectangular frame and the spiral labeling processing is carried out in the segmented rectangular area only. Therefore no influence is caused by the movements of the mobile objects preventing out of the rectangular area. Then a closed area having the smallest distance from the centroid point set by a preprocessing frame is recognized as label number '1'. Thus it is possible to track the targeting mobile object without being affected by the newly intruding mobile objects as long as the distance between the centroid point and an entered mobile object is larger than the distance between the centroid point and the desired mobile object.

Title: Method for detecting trace amount of interactive gas
Inventor: DANIERU JIEEMUSU RAGUSUDEERU
IPC: G01N30/66
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To correctly detect a contained interactive gas with good sensitivity by adding a small amount of the interactive gas to a carrier gas before a gas chromatography is executed. SOLUTION: According to the method, a trace amount of an interactive gas such as oxygen, carbon oxide, hydrogen or the like included in a sample gas mixed with a carrier gas is detected with the use of gas chromatography. A trace amount of the interactive gas is added to the carrier gas at the upstream. More specifically, a known amount of the interactive gas, e.g. oxygen or the like contained by trace amount in the gas is added into a detecting device, so that a part reactive or adsorptive to the interactive gas in the device is saturated. Accordingly, detection efficiency by the gas chromatography for the trace amount of the interactive gas, e.g. oxygen impurities or the like can be improved. The interactive gas added to the carrier gas is preferably less than 10ppm.
