Title: Tape guide
Inventor: SARUWATARI KIYOSHIGE
IPC: G11B15/61
Filed: 1989-02-21
Abstract: PURPOSE:To prevent a magnetic tape from being damaged at the time of winding the magnetic tape in the state that the magnetic tape does not have the tension on it by disposing a magnetic tape leading member and a tape height controlling member in a post roller base. CONSTITUTION:When a post roller conveying means 17 rotates, the rotation is transmitted to the pulley part of a gear arm 23 through a belt 18 and unloading is performed along a loading path 3 by post rollers 11 and 21 by the rotation of gear arms 13 and 23. Then, the magnetic tape 2 is led in by the leading member 116 which is planted on the post roller base 111 in the state that reel bases 14 and 24 are not rotated, and the tape deviation in height is prevented by the planted surface of the leading member 117. By such constitution, even when the tape is wound in the state that the sagging of the magnetic tape 2 occurs, because of not having the tension on the tape 2, the back and forth direction of the magnetic tape 2 can be held and also the up-and-down direction thereof can be controlled and also the deviation in height can not occur, so that the damage of the magnetic tape 2 caused by touching the end surface of the lower flange 113 can be prevented.

Title: Semiconductor device
Inventor: OISHI AKIO
IPC: H01S5/00
Filed: 1986-02-28
Abstract: PURPOSE:To obtain a highly reliable semiconductor device such as a lateral single-mode semiconductor laser having a low threshold current value which is not changed in association with lapse of operating time, by utilizing InGaAsP layers for all or a part of semiconductor layers forming NPN- or PNP-type junctions. CONSTITUTION:All or a part of semiconductor layers forming PNP- or NPN- type junctions are formed of InGaAsP. For example, an InGaAsP active layer 7 and a P-type InP layer 8 are formed on an N-type InP substrate 1 by means of the liquid-phase growth process. After that, a mesa stripe is formed with the active layer 7 of a width of about 1mum left. A P-type InGaAsP layer 2, a P-type InP layer 3 and an N-type InP layer 4 are formed on opposite sides of the mesa by means of the liquid-phase growth process. Subsequently, a P-type InP layer 5 and a P-type InGaAsP layer 6 are grown on the whole surface to produce a semiconductor laser. In this contruction, the layers 4, 3 and 2 and the substrate 1 constitute an NPN structure in which an intermediate P-type layer is provided by the InGaAsP layer 2. These layers act as current blocking layers for preventing electric current from flowing out of the active layer.
