Title: Image reading device and image forming device
Inventor: NAKASHIGE FUMIHIRO
IPC: G03B27/54
Filed: 2003-01-29
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image reading device which can be prevented from deteriorating its image reading performance due to the influence of secondary illuminating light by eliminating the intensity change of the secondary illuminating light corresponding to the density of the image of a manuscript.  <P>SOLUTION: The image reading device is equipped with a light source 9 illuminating a manuscript surface 8a, and reads the images on the manuscript surface 8a successively in a main scanning direction. The image reading device is equipped with a light diffusion member 12 provided with a diffusion surface 12a, and the light diffusion member 12 is arranged so as to make the diffusion surface 12a confront the manuscript surface 8a and not to shade the primary illuminating light A that is emitted from the light source 9 to reach the manuscript surface 8a. By this setup, the diffusion surface 12a reflects the light reflected from the manuscript surface 8a again over a wide range as secondary illuminating light B, whereby the difference between the amounts of the light reflected from the manuscript surface 8a is restrained from becoming identical to the difference between the secondary illuminating light B illuminating every part of the manuscript surface 8a, even when the density difference between the images of the manuscript surface 8a causes the difference between the light reflected from the manuscript surface 8a. Therefore, the secondary illuminating light B illuminates every part of the manuscript surface 8a almost uniformly.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Title: Stop and start control device of internal combustion engine
Inventor: KATAOKA KENJI
IPC: F02D45/00
Filed: 2003-01-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a stop and start control device of an internal combustion engine, realizing the premature ignition starting of the internal combustion engine by stopping the internal combustion engine in such a position as to lower the energy in starting.  <P>SOLUTION: In controlling the stop of the engine, a cylinder entering a compression stroke and/or expansion stroke in stopping the engine is estimated. When the cylinder enters the intake stroke immediately before the engine stop control, fuel is supplied into the cylinder through an intake port. After that, it is stopped in such a crank angle position as to lower the torque of a motor required for starting the engine. In starting the engine, fuel enclosed in the cylinder is burned. Thus, the time to the initial explosion can be reduced to quickly start the engine.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Title: Optical waveguide, its manufacturing method, and optical device

Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical waveguide which reduces the light amounts radiated outside the bent sections of the waveguide and in the direction to the circuit substrate, even if the curvature radius is made small for the bent sections of the waveguide.  <P>SOLUTION: This is a three-dimensional optical waveguide that is formed by depositing and spreading a diffusion material in the waveguide on a substrate 2 to increase the refractive index and has a straight sections 6a and bent sections 6b. The amount of the diffusion material is increased inside the waveguide 15a but decreased outside the waveguide 15b at the bent sections 6b referencing the average amount of the diffusion material in the straight sections 6a so that the peak of the refractive index curve is shifted to the inside of the bent sections 6b. In this configuration, the effect of the mismatching mode is prevented by making the changes of the refraction index nearly equal in the straight sections and the bent sections after spreading the diffusion material. By increasing the refractive index in the bent sections and decreasing it outside the waveguide to make the light transmission smooth at the bent sections, an optical waveguide is obtained, which reduces the light amount radiated to the outside of the waveguide and radiated in the direction to the substrate, even if the curvature radius is made small at the bent sections.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

IPC: H04J11/00
Filed: 2003-02-24
Abstract: <P>PROBLEM TO BE SOLVED: To improve the error rate in a space division multiplex OFDM receiver.  <P>SOLUTION: The reference for selecting a reception system in selection diversity reception is based on the size of the sum of the electric power of transmission functions of respective transmission antennas for the respective reception systems. In the prescribed reception system, the electric power of the transmission functions with the respective transmission antennas shows the received electric power when a signal is independently transmitted from each transmission antenna. Thus, the electric power of the transmission function reflects the received electric power in a state where a space division multiplex OFDM signal is separated into OFDM signals transmitted from the respective transmission antennas. Namely, the reception system where SNR of a reception signal is improved is selected and the error rate characteristic is improved by selecting the reception system on the basis of the received electric power in a state where the space division multiplex OFDM signal is separated into the OFDM signals transmitted from the respective transmission antennas.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
