Title: Manufacture of plate for lead storage battery
Inventor: KONISHI HIROSUKE
IPC: H01M4/21
Filed: 1983-04-01
Abstract: PURPOSE:To improve the active-material-holding ability of a plate by ageing a non-dried plate in an atmosphere containing a given amount of CO2 after the plate is prepared by packing a paste containing a sodium salt into a grid. CONSTITUTION:Na2CO3 powder is added to a paste prepared by the usual method in such a manner that the amount of Na2CO3 powder is 0.5% of the weight of lead powder. The thus obtained paste is packed into the usual plate grid for an automatic battery having 1mm. thickness to make a plate which is then dried in a dryer at 150 deg.C for three minutes. At this point, the moisture content of the plate is over 5%. The thus obtained plate is aged in an atmosphere of carbon dioxide for 24hr before being subjected to vacuum drying at 110 deg.C for one hour. According to a vibration test carried out in order to investigate the amount of the active material separated from the thus treated plate, the best result was obtained by carrying out the ageing in an atmosphere containing 1-25% of CO2.

Title: Self-excited oscillator
Inventor: NAKAMURA SHIGERU
IPC: H02M3/338
Filed: 1984-03-27
Abstract: PURPOSE:To reduce a power loss and to prevent a switching transistor from damaging by increasing the bias amount of the base current of the transistor when the collector current of the transistor increases. CONSTITUTION:A DC power source 1 is supplied to a series circuit of the primary winding 4 of a transformer 2 and a switching transistor 3. The transistor 3 is controlled OFF by the ON of an OFF control transistor 24. When the collector current of the transistor 3 increases, a voltage higher than the threshold value is applied to between the base and the emitter of the transistor 24 and the collector current increases, the bias amount of the base current of the transistor 3 increases, and the transistor 3 is abruptly turned OFF. When a base current more than necessary is flowed to the transistor and the collector current tends to become excessive, the transistor 24 is automatically turned ON.

Title: Magnetic tape recording and reproducing method
Inventor: MIHASHI YASUO
IPC: G11B27/28
Filed: 1978-05-16
Abstract: PURPOSE:To easily record and detect a position recognizing signal by making the gap of a recording and reproducing head of the position recognizing signal large than that of the recording and reproducing head which is in contact with the opposite recording side of a magnetic tape. CONSTITUTION:In a magnetic tape which is recorded with a video signal on a magnetic side A in the region of a video width and a position recognizing signal on a side B, the relationship between the gap g1 of the head 24 representative of the recording and reproducing heads of the position recognizing signals and the gap g2 of the head 31 representative of the video head is determined such that g1 far larger than g2. Then, among the head gap g, the tape-head relative speed V and the possible recording frequency f, there is established a relationship of g<V/2f. As a result, if a low frequency position recognizing signal is recorded, the video signals at the opposite side are detected by the reproducing head in the last. Since, on the other hand, the video signal and the position recognizing signal is different in the angle of the recording and reproducing head, little influence is exerted upon the video signal from the position recognizing signal due to the azimuth loss effects.
