Title: Semiconductor laser device and its manufacture
Inventor: TOYONAKA TAKASHI
IPC: H01S5/00
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To sufficiently narrow the width of a narrow mesa structure, and to reduce the capacity of an element without increasing element resistance by setting a planarizing layer to a reverse mesa shape through wet etching, and by etching a groove nearly vertically by dry etching until the groove reaches a p-InP substrate. SOLUTION: An n-InP flattening layer 110 is subjected to wet etching by HBr/H3 PO4 family etching liquid until it reaches an n-InGaAsP etching stop layer 109, and a reverse mesa shape is formed. Then, the n-InGaAsP etching stop layer 109 is eliminated and is etched nearly vertically by dry etching until a groove 116 reaches a P-InP substrate 101, thus sufficiently widening width W2 of a window in contact with an n-electrode 113, since width W12 of narrow mesa structure can be made adequately wide in an n-InGaAsP cap layer 111, suppressing the increase in element resistance, and reducing the capacity of an element.

Title: Manual paper feed device
Inventor: MAEHARA HIDEJIRO
IPC: G03G21/00
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To quickly feed paper with paper feed efficiency equal to that of an ordinary automatic paper feed device by providing a manual paper feed device with two modes of a manual feed mode bringing a bottom plate down to a position capable of feeding no paper at every completion of a job, and a cassette equivalent mode holding the bottom plate on a raised position capable of feeding paper even after completion of the job, and constituting the motion of the device such that either of the modes can be selected.

Consequently, when a manual paper feed is executed after power supply, a paper sheet is on the upper limit position, and the initial paper feed motion can be started without delay. Meanwhile, in the case of a manual insert mode, the bottom plate 1b is left to be brought down on the initial position, it is raised for the first time at starting paper feed, and the paper sheet on the bottom plate is moved to the position capable of feeding paper. Accordingly, compared with the case of the cassette equivalent mode, delay is generated in the initial paper feed motion. This device is constituted either of both modes as the method controlling manual feed selectable.
