Title: Manufacture of metallic welded tube
Inventor: NAKAKO TAKEFUMI
IPC: B23K26/21
Filed: 1990-03-02
Abstract: PURPOSE:To form the diameter of a through hole on the outlet side at the same time in the form of a tube of the same outer diameter by passing a metallic plate through a die provided with a through hole of a circular section section having a tapered part in which a diameter is reduced from the inlet side to the outlet side thereof. CONSTITUTION:A metallic plate 1 is passed through a through hole 3 of a circular section having a tapered part in which the diameter is reduced from the inlet side of the die to the outlet side thereof. In the process in which this through hole 3 is passed, the metallic plate 1 is bent along the tapered part and elongated in the lengthwise direction, therefore, when the flat metallic plate 1 is passed through the through hole 3 of the die 2, it can be formed at the same time into the form of a pipe having the same outer diameter with the diameter of the through hole on the outlet side. Thereafter, as the tube form is held by squeeze rollers, the butted part of both side edges of the strip is TIG-welded. In this way, when the outer diameter of the metallic pipe to be manufactured is changed, die changing can be performed in a short time and easily.

Title: Optical recording and reproducing device and optical recording medium used therein
Inventor: TEZUKA MASARU
IPC: G11B7/24035
Filed: 1994-03-18
Abstract: PURPOSE:To form an optical recording and reproducing device which substantially improves the life (number of repetitive reproduction times: read stability) of an optical recording medium, such as optical disk or MO recording medium, in a still operation mode. CONSTITUTION:The number of repetitive reproduction times (read stability) is of problem as the same tracks are repetitively subjected to reading out in the still operation mode. The MO recording medium 100 discriminates a save region 101 and a data region 103 of the MO recording medium 100. The save region 101 is subjected to seeking to prevent deterioration of the data region 103 and to improve the read stability of the data region 103 in the still mode. The save region 101 is merely necessitated to read the addresses and the read stability is of not so much problem therewith.

Title: Fault point locating device
Inventor: KONO MASAYUKI
IPC: G01R31/08
Filed: 1992-03-10
Abstract: PURPOSE:To make a locating distance as close as possible to a registered distance so as to reduce the inspecting extent of a steel tower by dividing a sag correcting coefficient found from artificial earthing tests into fault occurring sections by utilizing the locating result of a new power supply trouble and correcting the sag of the transmission line to a sag correcting coefficient meeting the fluctuation of the sag. CONSTITUTION:When a power supply trouble occurs in a transmission line, a sag correcting coefficient is newly calculated for the transmission line by dividing the line to two sections on this and other sides of the fault point from the distance then detected by means of the locating device and a registered distance for managing the fault point discriminated as a result of a transmission line patrol. A sag correcting coefficient found from artificial earthing tests and applied to the total length of the transmission line is divided to three fault occurring sections by utilizing the locating result of the new power supply trouble. Then the sag correcting coefficient is corrected to a sag correcting coefficient meeting the sag fluctuation of the transmission line. By storing the corrected coefficient in a memory M2 (for storing sag correcting coefficients) corresponding to a memory M1 (for storing registered transmission line distances), the locating distance can be make as close as possible to a registered distance and the investigating extent can be reduced.

Title: Video signal recording and reproducing device and its recording and reproducing method
Inventor: MORIOKA YOSHIHIRO
IPC: H04N9/815
Filed: 1986-03-07
Abstract: PURPOSE:To contrive high-density recording as well with an extremely simple constitution by equalizing the time of one turning of a rotary cylinder with a vertical synchronization period, switching, within one track, a luminance signal and a chrominance signal that are time base compressed, and recording and reproducing with two magnetic heads of different azymus angles. CONSTITUTION:A vertical synchronizing signal enters a memory read/write timing control circuit 11 to determine the read/write timing of the first and the second memories. Signals (c) and (d) that are time base compressed by two times and switched alternately at every horizontal synchronization period, are made a signal (e) and the signal (e) enters an AM modulator 6. Output signals from the modulator 6 are recorded in a magnetic tape by magnetic heads whose azymus angles are different from each other. Since the rotary cylinder turns one time during one vertical synchronization period of the signals (c) and (d), a track pattern in which the luminance signal of different recording azymus angle is recorded in the neighborhood the luminance signal, and the chrominance signal of different azymus angle in the neighborhood of the chrominance signal, is obtained.

Abstract: PURPOSE:To reproduce a clear picture by adjusting and recording the phases of already recorded contents and contents to be newly recorded in a helical scanning type video tape recorder. CONSTITUTION:At the time of insert, i.e. recording of another new signal in an area of a magnetic tape 7 where a signal has been already recorded, coincidence of the phases of pulse from a pulse signal generating circuit 27, a control signal read out from a magnetic tape 7 and a vertical synchronizing signal from a vertical synchronizing signal generating circuit 37 causes normal recording state, so that recording in the magnetic tape 7 is started. When the time set up in a memory coincides with the tape traveling time counted by a counter, a motor driving circuit 25 stops a motor 21. Thus, fixed data are recorded in an area erased by a whole width erasing head. Therefore, so-called cut-off state of a signal is prevented at the time of reproduction.
