IPC: G03B17/02
Filed: 2002-10-15
Abstract: <P>PROBLEM TO BE SOLVED: To maintain an optical performance and reliability of electric characteristics properly without increasing in size and cost of an imaging apparatus.  <P>SOLUTION: In a digital camera 10, a CCD package 14 is provided without contact with a circuit substrate 16.

IPC: H01L33/28
Filed: 2002-10-23
Abstract: <P>PROBLEM TO BE SOLVED: To provide an oxide semiconductor light-emitting element that uses a high-stability material and realizes high-efficiency visible light emission.  <P>SOLUTION: At least an n-type ZnO-based semiconductor clad layer 2, a ZnO-based semiconductor active layer 3, and a p-type ZnO-based semiconductor clad layer 4 are successively deposited on a substrate 1. The ZnO-based semiconductor active layer 3 is a quantum well structure having a well layer and a barrier layer. The well layer is made of Zn, O, and another group VI element S, and is doped with B, Al, or Ga which is an n-type impurity element smaller than Zn in terms of ionic radius. Crystals of ZnO and ZnS when mixed reduce the band gap energy for enabling emission at wavelengths not shorter than 400 nm. Since the n-type impurity element is smaller than Zn in terms of ionic radius, grid distortion attributable to the difference in bond lengths between elements in groups II-VI is eased for improvement in crystallinity.  <P>COPYRIGHT: (C)2004,JPO

Title: Compression ratio control device of internal combustion engine
Inventor: SUGIYAMA TAKANOBU
IPC: F02B37/12
Filed: 2002-11-05
Abstract: <P>PROBLEM TO BE SOLVED: To achieve compatibility between acceleration responsiveness and improvement of fuel consumption by making compression ratio control at the time of acceleration appropriate.  <P>SOLUTION: The internal combustion engine is equipped with a compression ratio variable mechanism utilizing a dual-link type piston-crank mechanism, a turbo supercharger and an inter cooler. An intake air temperature sensor is provided at an outlet of the inter cooler to detect the inter cooler outlet temperature ICTemp. When an acceleration in which an accelerator pedal opening APO rapidly increased was detected, it determines correction amount of compression ratio, and corrects a target compression ratio based on the difference between the inter cooler temperature ICTemp and the intake air temperature in a steady state. Since the change of the intake air temperature has a time constant depending on a heat capacity of the inter cooler, the intake air temperature in an initial acceleration stage is lower than that in the steady state, and knocking hardly occurs, it is possible to increase a compression ratio ε. The acceleration response and fuel consumption are improved by correcting as shown in a dashed line.  <P>COPYRIGHT: (C)2004,JPO
