Inventor: WAI HAN
IPC: G03G5/04
Filed: 1991-12-16
Abstract: PURPOSE: To enable obtaining high photosensitivity to radiations in the near-IR region of electromagnetic spectra by incorporating a conductive base, a charge generating material contg. near-IR photosensitive org. pigments and a specific aggregate photoconductive material into the element. CONSTITUTION: This photoconductive element contains the conductive base, the charge generating material contg. the near IR photosensitive org. pigments and the aggregate photoconductive material which is adjacent to this charge generating material and contains a continuous electrically insulative polymer phase dispersed with a complex composed of a polymer having an alkylidene diarylene group in an iterative unit and pyrilium dyestuff salt. The electrophotographic element or the multilayered element of a receptor has both of a charge generating layer and a charge transfer layer which are electrically adjacent to each other. Near IR photosensitive pigments can exist in the charge generating layer and the aggregate material may exist in either of these layers or the separate layer of the multilayered element.  The single- layer element is formed by applying the layer which is the charge generating material and contains the aggregate material and the pigments on the conductive base.

Title: Semiconductor lamination structure
Inventor: NAKAMURA SHUJI
IPC: H01L21/205
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To improve crystallinity of a GaN layer and an InGaN layer by making InGaN to grow on a GaN layer or an AlGaN layer formed on a buffer layer which formed at a low temperature. SOLUTION: After a sapphire substrate 7 is set in a susceptor 2 and a buffer layer is formed, a GaN layer is formed. After a GaN layer is formed, InGaN is made to grow. Thereby, a semiconductor lamination structure is made single crystal of an InGaN layer. Since a buffer layer is formed on a sapphire substrate at a low temperature before a GaN layer is formed, crystallinity of a GaN layer to be formed thereon is further improved and crystallinity of InGaN is also improved. Since a semiconductor material which is laminated in a blue light emission device can be thereby made a double hetero structure, a blue laser diode can be realized.

Title: Paper-feed controller for printer
Inventor: YAMAGUCHI NAOTO
IPC: B65H7/02
Filed: 1989-12-22
Abstract: PURPOSE:To detect the thermal expansion of a platen altering with extremely large retardation to the change of an ambient temperature, and to control paper-feed with high accuracy by detecting the ambient temperature by a temperature detecting means with the same thermal inertia as the platen. CONSTITUTION:When a temperature in a printer casing is elevated by a motion for a prolonged time, the temperature of a platen 1 is also raised so as to follow up the temperature rise in the casing, but the temperature is varied with a delay time DELTAt to the temperature change in the casing because the platen 1 has comparatively large heat capacity. Since a cover 9 is mounted around a temperature sensor 8 by a substance having the same material as the platen 1 in the temperature sensor 8, on the other hand, the temperature is altered through the same process as the temperature change of the platen 1. Consequently, a temperature data corresponding to the temperature change of the platen 1 is input to a paper-feed error arithmetic circuit 14 even when the temperature of the platen is varied during printing. Accordingly, a pulse-motor driver circuit 6 outputs driving pulses corresponding to the thermal expansion of the platen changing every hour.
