Title: Detector for tape run state
Inventor: NARITA HISAYA
IPC: G11B15/093
Filed: 1978-09-04
Abstract: PURPOSE:To make it possible to detect accurately a tape position by making use of a differential operation between a rotating body turning synchronizing with a reel desk and that turning at a constant speed. CONSTITUTION:Rotating body 10 turns synchronizing with a reel desk, and rotating body 11 turns at a constant speed in the same direction. The rotational speed of rotating body 11 is set a little bit lower than the lowest rotational speed of rotating body 10, so that rotating body 10 will turn faster than rotating body 11. However, when rotating body 10 stops rotating at the end of a tape run, rotating body 11 turns faster to the contrary. At this time, needle 36 is engaged to force rotating body 12 to turn and auto-shut OFF operation is performed by arm 23. When the rotation speed of rotating body 11 is set a little bit higher than the lowest speed of rotating body 10 this time, befor-end-alarm operation is performed. In this way, the tape position can accurately be detected by the simple mechanism.

Abstract: PROBLEM TO BE SOLVED: To eliminate effects of the growth and stay of bubbles by a filter and stabilize a printing quality by setting the filter in a manifold and separating the manifold to a first manifold at the side of an orifice arrangement and a second manifold at the side of a reservoir. SOLUTION: A plurality of rows of orifices 1 for discharging ink are set to an orifice plate 12. Pressure chambers and restrictors 7 corresponding to the orifices 1 are arranged to a pressure chamber plate 11 and a restrictor plate 10 respectively. A filter plate 28 is interposed between a first and a second manifold plates 14 and 15, thereby separating a manifold from an upper end to a lower end to two chambers, i.e., a first manifold 20 and a second manifold 21. Bubbles entering wrong from the filter 28 are hard to flow into the thin restrictors 7 and therefore stay in the first manifold 20. Nozzles 1a of an uppermost part communicating with the first manifold 20 are used as dummy nozzles to more surely eliminate effects of bubbles.

Abstract: PURPOSE: To provide a polarization independent and high gain optical semiconductor device. CONSTITUTION: A tensile strain quantum well 11 and a compressive strain quantum well 12 are provided in an active layer 4, and a carrier is injected thereinto and a gain is generated. In this case, a gain is generated in the tensile strain quantum well 11 for the light propagating in the direction 15 for both of TE and TM polarizations, but when the tensile strain exceeds a certain extent the gain increases mainly for the TM polarization, and in the compressive strain quantum well 12, the gain increases mainly for the TE polarization. Thereupon, by adjusting the tensile strain amount, the compressive strain amount, the layer thicknesses, the composition, and the number of layers, the ratio of the gains given in the whole quantum well layers to the TE polarization/TM polarization components can be made approximately equal to 1. Namely, it can be made polarization independent.
