Abstract: PURPOSE:To surely attract a sheet material in an electrostatical manner so as to hold and convey the sheet material without slipping the same, by providing a holding and conveying member made of inductive materials and a means for applying an alternate voltage to the holding and conveying member. CONSTITUTION:An alternating charge density pattern is formed on an outer surface of a holding an conveying member 2 made of inductive materials by a means for applying an alternate voltage to the holding and conveying member 2, and a position from which a sheet material 1 or the like is fed to the holding and conveying member 2, is set in a range where it can make contact with a counter electrode of a voltage applying means 5'. Accordingly, since the sheet material 2 such as an image-transfer sheet or the like which is inductive is fed to the holding and conveying member 2 within such a range that it can make contact with the counter electrode of the voltage applying means 5', it is attracted by a strong attraction force onto the holding and conveying member 2 under an uniform electric field and is held without slipping.

Title: Semiconductor laser element
Inventor: UCHIDA KENJI
IPC: H01S5/323
Filed: 1995-03-20
Abstract: PURPOSE: To separate the crystalline surface of an active layer for generating a light gain without damage when laser elements formed of nitride compound semiconductors are individually separated. CONSTITUTION: A rectangular or stripe vertical stepped region is formed on a substrate 1, and a laser element made of nitride compound semiconductor is crystalline grown on the substrate. As a result, it becomes the structure of the state in which the active layer 7 of an element structure is brought into contact with the substrate 1. Further, it becomes the structure in which the substrate is disposed perpendicularly to the optical axis of the active layer for generating a light gain. The formation of these laser element structures can be realized by selectively growing an insulating film mask such as an SiO2 on the substrate formed with a step region by dry etching on the substrate by an organic metal vapor growing method. Thus, the effect of easily manufacturing a resonator structure indispensable for the laser oscillation of a nitride compound semiconductor laser is provided.
