Title: Optical pickup system
Inventor: CHOI YANG OH
IPC: G11B7/123
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To simplify the structure of an optical pickup device and to miniaturized the device, by incorporating an optical device having a cylindrical lens and a reflection plate into the device to enable a photodetecting part to be arranged in the vicinity of a light source. SOLUTION: When the outgoing light of a light source 210 is made incident on a beam splitter 220, whose reflection surface 224 transmits a part of the light beam toward an objective lens 230, and since the surface 224 reflects a residual light beam, the residual light beam is not used for reproducing the signal of recorded information being on the recording surface 242 of an optical disk 240. Then, after the reflected light beam of the recording surface 242 is converged with the objective lens 230, it is reflected with the reflection surface 224 of the beam splitter 222 toward an optical device 250. Then, this reflected light beam is made incident on a cylindrical lens 254, which raises an astigmatism in the incident light beam and reflects it toward a photodetecting part 260. Consequently, the photodetecting part 260 detects a focus error signal by using an astigmatism method.  Here, the photodetecting part 260 is enable to be positioned in the vicinity of the light source 210 by allowing a reflection plate 252 to be attached to the flat surface of the cylindrical lens 254.

Abstract: PROBLEM TO BE SOLVED: To simplify the assembling process and required parts by forming a groove part on the lower end circumferential surface of the lower end plug of a thimble pipe, and forming a hooking projection to be fitted into the groove within the thimble cell of a support grid of the bottom part. SOLUTION: A support grid 3' of the bottom part is fixed in contact with a lower nozzle 5, and a circumferential, groove 7 is formed on the lower end circumferential surface of the lower end plug 6 of a thimble pipe 2. A hooking projection 9 to be fitted into the circumferential groove 7 is formed within the thimble cell 8 of the support grid 3', and protruded from four wall surfaces of the cell 8, respectively. The thimble pipe 2 is fixed to the nozzle 5 by a thimble screw 10. The lower end surface of the end plug 6 is brought into contact with the circumference of a thimble screw hole 12. Since the fixation of the support grid 3; is performed by the fitting of the circumferential groove 7 with the protruding part 9, the swage fixation by use of a sleeve pipe is dispensed with, and the longitudinal regulation by a bushing is also dispensed with. Further, the wedding between the grid 3' and the sleeve pipe, or between the bushing and the nozzle 5 is also dispensed with.

Title: Production of structural hot-dip coated steel excellent in resistance to white rust and chromium (vi) ion elution
Inventor: UCHIDA YUKIO
IPC: C23C22/26
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To obtain a coating film having excellent white rust resistance, from which Cr(VI) is hardly eluted and compatible with environment by dipping a hot-dip coated structure in a chromating soln. with the Cr(VI) reduced to Cr(III) by a hydroxycarboxylic acid compd. SOLUTION: Tartaric acid, citric acid, etc., are exemplified as the hydroxycarboxylic acid compd. The concn. of a water-soluble Cr compd. is controlled to 0.1-20g/l total Cr. When the ratio of Cr(VI)/total Cr is controlled to <=0.1 by reduction, the elution of Cr(VI) is almost completely prevented during storage, and further, the coating film obtained is made practically colorless. The reduction of Cr (VI) by the hydroxycarboxylic acid compd. is promoted by adding an appropriate amt. of phosphoric acid or a phosphoric acid compd. to the processing soln. In this case, a part of the coating film is converted to a sparingly-soluble chromium phosphate coating film, and the white rust resistance is also improved.

IPC: G04G9/00
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To provide an image display control device and method for performing display while changing an image according to intimacy. SOLUTION: In a step S24, standby is made until a specific amount of time such as one hour passes and '1' is added to the value of an intimacy level L being stored in an intimacy level register for updating. Also, it is judged whether a detection temperature A from the body of a user is less than 33 deg.C or not (step S27). Then, when the detection temperature A is less than 33 deg.C, '1' is subtracted from the value of the intimacy level L for updating (step S28). When the temperature A is equal to or more than 33 deg.C, '1' is added to the value of the intimacy level L for updating (step S28). Then, when the value of the intimacy level L becomes equal to or more than a specific value B, move is made from the step S30 to the step S31 to display an intimacy image.  By the processing in the step S31, an image for friends where characters indicate affection is displayed at a display part.
