Abstract: <P>PROBLEM TO BE SOLVED: To miniaturize an electric connector assembly and a cap connector used for the same.  <P>SOLUTION: A convex part for fitting 12 of a plug connector 1 is housed in a concave part for fitting 62 of a cap connector 50 when those connectors 1, 50 are completely fitted to each other, at this time, a contact part at one side 80a of a contact 52 contacts with a contact point 34 of the contact 2, and the contact part at the other side 80b is inserted into a supporting groove 24 of the convex part for fitting 12. The contact pressure generated by the contact of the contact point 34 and the contact part 80a makes the contact part at the other side 80b move toward the convex part for fitting 12, and this contact pressure is supported by the side wall of the convex part for fitting 12. By the above, as an outside wall 84 of the cap connector 50 supporting the contact part 80a does not directly receive the pressure generated by the mutual contact of both contacts, and apprehension of deformation is eliminated, the size of the cap connector 50 can be miniaturized by making the wall thickness of the outside wall 84 thin.  <P>COPYRIGHT: (C)2004,JPO

IPC: B01D46/42
Filed: 2002-04-12
Abstract: <P>PROBLEM TO BE SOLVED: To remove sulphate reserved in a particulate filter by adding HC without early clogging of the particulate filter.  <P>SOLUTION: HC is added to exhaust gas 8 upstream of a catalyst regeneration type particulate filter 10, and a catalyst bed temperature at a rear portion of the filter 10 is raised by reaction heat on an oxidation catalyst of the filter 10 of the HC, so as to gasify and eliminate the sulphate reserved here.

Title: Objective lens for optical pickup device, optical pickup device and method for recording/reproducing information
Inventor: SAKAMOTO KATSUYA
IPC: G02B5/18
Filed: 2002-04-12
Abstract: PROBLEM TO BE SOLVED: To provide an objective lens for an optical pickup device and an optical pickup device each having a simple structure with which the recording or the reproducing of information is properly performing on different optical information recording media, and a method for recording and reproducing information. SOLUTION: The transmissivity of a luminous flux having a wavelength λ2 for a CD(compact disk) is lower than the transmissivity of a wavelength λ1 for a DVD(digital versatile disc) thus reflection light from the CD is hardly detected with an optical detector 106 which detects the reflected light from the CD, thus the possibility of an erroneous detection is suppressed even when the overflare part of the luminous flux used for recording or reproducing information on the CD is directed to the under direction due to the enhancement of the wavelength-dependency of a diffraction structure and accordingly the flare part approaches to an optical axis.

Title: Method and apparatus for controlling feeding of optical pickup
Inventor: SHIGETA KOJI
IPC: G11B7/085
Filed: 2002-04-15
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that a stepping motor which is the feeding mechanism of an optical pickup sometimes cannot perform seeking because supply torque is short due to the variation of loads.  <P>SOLUTION: A target distance to a seek moving destination address from a present address read from a disk 1 is calculated, and the stepping motor 14 is driven by the number of application pulses equivalent to the target distance. Thereafter, the present address on the disk at the seek moving destination is read to calculate an actually moved distance. Then, actually moved distance is compared with the target distance. When the actually moved distance is shorter than the target distance and both of them are in a proportional relation to each other, a track pitch correction coefficient is calculated. When they are not in a proportional relation, it is decided that the driving torque is short and a pulse rate is lowered. This processing is repeated several times and the stepping motor 14 is driven with a pulse rate when both of them become nearly coincident with each other.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a novel video encoding technology capable of remarkably suppressing a produced encoding amount in encoding control of a video encoding.  <P>SOLUTION: The novel technology positively applies the NotCoded system to an encoding object macro block wherein a few amounts of DCT coefficients are produced due to noise regardless of that no image change is viewed or an encoding object macro block wherein an image change is hardly detected as a visual characteristic. The NotCoded system is a system encoding is available by having only to indicate 1-bit information denoting absence of encoding information when almost no image change exists by comparing an encoding object macro block with a macro block at the same position in a preceding frame and can remarkably suppress the generated encoding amount for the encoding object macro block with no image change. Thus, it is possible to assign many more coding amounts to other macro blocks whose encoding is difficult and the enhancement of the image quality of the entire frames can be realized.  <P>COPYRIGHT: (C)2004,JPO

IPC: B41J29/46
Filed: 2002-04-26
Abstract: PROBLEM TO BE SOLVED: To provide a method of calibrating a color output for compensating various changes in an image color after printing in an image forming system. SOLUTION: In this method, an appearance of a test patch which is printed by an image forming system after the test patch is stabilized, is predicted by applying a transfer function to the color of the test patch newly printed. The transfer function can be made in a formula by taking into account various environmental conditions such as a humidity, a temperature or the like, or a treatment after printing such as laminating. An image forming system processor can compare the color of the predicted test patch after the stabilizing with a desired color of a test patch in order to calibrate a color map to be used in the image forming system.
