IPC: G11B15/00
Filed: 1984-02-24
Abstract: PURPOSE:To obtain always a stable output by providing an automatic inversion release means which can run a trailer part, which is connected to the end part of a magnetic tape and has a cleaning effect, up to the surface of a magnetic head when automatic inversion is released at a reproducing time. CONSTITUTION:An open/close switch 6 for optional automatic inversion is provided in the output side of a photo sensor 1 to turn on/off a detection signal. This open/close switch 6 is provided on an external operation panel of a DAT recorder, and a user operates this switch 6 optionally in accordance with contents of recorded sounds at a reproducing time, and the switch 6 is set preliminarily to the cut-off state when momentary inversion is unnecessary. As the result, the DAT recorder can not detect the end part of a sound recording tape part 3, and a tape T runs up to the terminal, and then, running of the tape T is stopped by a control means (omitted in the figure) using the tape tension. By this operation, the tape T is run up to the terminal, and a trailer part 4 used as a cleaning tape passes a magnetic head 2 to clean it.

Abstract: PURPOSE:To attain visual test, by transmission and reception of a test facsimile signal between facsimile terminals and of a control signal between central processing sections, in the test equipment provided for a station device in a facsimile communication network. CONSTITUTION:In testing the presence/absence of a failure between a facsimile data connecting device FDIC and a facsimile storage converter STOC, a test facsimile signal is transmitted from an STOC 4a and the signal is stored in a picture signal storage section 10 via an inter-station transfer section 9.

Abstract: PROBLEM TO BE SOLVED: To reduce variations in current-interrupting action by controlling the pressure of current interruption related to displacement (deformation) of a wall. SOLUTION: A wall 21 is joined to a contact conductor 22 with an intermediate joint 28 between them. A thin-walled part 28a made by a recess is formed in the intermediate joint 28, and if a force is applied to the wall 21 by the buildup of the internal pressure of a container 1, the intermediate joint 28 ruptures at the thin-walled part 28a prior to the rupture of the wall 21, thereby interrupting the conduction between the wall 21 and the contact conductor 22. Also, a rupturing blade 29 secured to the container 1 is contacted with and ruptures the wall 21 displaced by the buildup of the internal pressure after current interruption.

Title: Optical disk reproducing device
Inventor: SAKAKIBARA HIROO
IPC: G11B20/18
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency in reproducing retries concerning blocks in which read errors are consecutively generated. SOLUTION: When a read error is generated during the reproducing of an arbitrary block recorded on an optical disk 2, the optical disk 2 is reproduced without incurring a read error by executing retries for rereads while gradually decelerating the rotational speed of the optical disk each time plural retries as to the same block are executed and also retries accompanying decelerations of the rotational speed of the disk are executed. At this time, a reproduction enabled rotational speed for a final reproduction is stored, and when an error is generated during the reproducing of a next block, the number of retries is reduced by performing the gradual decelerations each time the retry is preformed one time until the rotational speed of the disk reaches the stored reproduction possible rotational speed.
