Title: Magnetic tape unit
Inventor: GOMI MUNECHIKA
IPC: G11B15/60
Filed: 1979-08-31
Abstract: PURPOSE: To prevent width-directional displacement without damaging the flanks of a tape by providing a guide part of section having a certain wind angle in the tape run direction and shaped in an arc in the width direction between two guide parts equipped with plane-shaped wind surfaces.  
     CONSTITUTION: Tape guide 15 consists of three guide parts 15a, 15b and 15c and guide part 15a has a wind surface a little bit lower in height than those of guide parts 15b and 15c and is equipped with a relatively long skirt. Tape 8 is wound around guide parts 15a and 15c between head 4 and capstan 6, but wound around guide part 15b at small wind angle α. Namely, since tape 8 is wound at angle α without floating over guide part 15b, section A-A of guide part 15b comes in hermetic contact with the arc-shaped wind surface to hole the tape-width-directional position. Thus, the width-directional displacement can be prevented without damaging tape flanks.

Filed: 1988-05-09
Abstract: PURPOSE:To obtain a semiconductor light emitting device which has a simple construction and is manufactured easily by utilizing a part of a light emitting element as a transistor. CONSTITUTION:The bottom layer of a current constricting layer 25 is reduced to make it function as a base layer 25A and a forward bias is applied between the current constricting layer 25 and an emitter layer 22. Further, a first cladding layer 26 with a conductivity type same as that of a semiconductor substrate 21 is made to function as a collector layer and a reverse bias is applied between the cladding layer 26 and the current constricting layer 25. Therefore, electrons injected from the emitter layer 22 into the base layer 25A is diffused in the base layer 25A and enter the first cladding layer 26, i.e. the collector layer, to produce a current between the first cladding layer 26 and the current constricting layer 25. As the current flows through the base layer 25A, the current flows through only the bottom layer of the current constricting layer 25, so that the purpose of current constriction can be achieved and, moreover, the switching operation of laser oscillation can be performed. With this constitution, a part of the light emitting element is made to function as an electric element, so that the construction can be simplified.

Title: Magnetic card and recording/reproducing method
Inventor: KATO HIROSHI
IPC: G11B5/80
Filed: 1990-05-01
Abstract: PURPOSE:To prevent forgery or alteration due to the transfer of data, etc., performed by writing true data on a true data recording layer by using a prescribed frequency, and writing false data on a false data recording la by using a frequency of (n)(n:positive integer) times the prescribed frequency. CONSTITUTION:The reproduction of the data is performed by erasing a record on the false data recording layer 2b by permitting a DC current to flow on a recording/reproducing head first. Thence, the record on the true data recording layer 2a is reproduced by the recording/reproducing head. A signal waveform reproduced at that time represents the true data. After that, the false data is written on the false data recording layer 2b. As a result, a magnetic card is returned to an initial state where the true data and the false data are recorded. A signal waveform on which the above signal waveform is superimposed can be obtained by reproducing the magnetic card by an ordinary recording/reproducing head. The signal waveform is represented as the one clearly different from recorded true data. In such a way, it is possible to prevent the forgery or the alteration due to the transfer of the data, etc., performed.
