Title: Water-soluble resist
Inventor: TSUYAMA KOICHI
IPC: H05K3/18
Filed: 1993-06-18
Abstract: PURPOSE:To prevent precipitation of lead on a board at the time of releasing by incorporating a specific organic material or an ingredient for generating its salt. CONSTITUTION:An organic material or an ingredient for generating its salt to be dissolved or decomposed in release liquid and represented by the formula is included in watersoluble resist which can be released with strong alkaline water solution (where, in the formula, N is tertiary amine bonded directly to a -CH2COOH group, R, R' are substituent groups or molecular chains). Thus, dissolution of solder plating can be suppressed, and precipitation of lead can also be suppressed. Thus, excellent wirings without wiring defect can be formed. As the other effects, even if inorganic alkali such as low-cost sodium hydroxide, potassium hydroxide, etc., is used as the releasing liquid for releasing this resist, damage of the solder is small, and it is not necessary to use expensive organic alkali. It is not necessary to add dissolution inhibitor of the solder to the release liquid, and the management of the releasing liquid is facilitated.

Title: Method and device for transmitting orthogonal frequency-division multiplex signal
Inventor: NAKAHARA HIDEKI
IPC: H04J11/00
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To precisely generate a time window timing clock by transmitting the amplitudes and phases of the specific number of specific frequency components by continuous multiplex modulation using a specific pattern and applying a superresolution method based upon characteristic value expansion for a correlation matrix of received data vectors of the specific frequency components on a reception side. SOLUTION: An estimation part 7 applies the superresolution method for the correlative matrix after movement averaging to find the delay time of a multiplex wave. The correlation matrix is expanded into characteristic values, which are sorted in the decreasing order. They can be divided into characteristic values corresponding to signal power and noise power and general characteristic vectors corresponding to the respective characteristic values are orthogonal to each other, so the delay time of the signal can be estimated. The delay time having the largest signal power among estimated delay times corresponds to the deviation of Clock-a from original time window timing and on the basis of the estimated value, a timing clock adjustment part 8 adjusts the Clock-a.

Title: Manufacture of sheet virtually free from optical anisotropy
Inventor: UEKI TOORU
IPC: B29C48/21
Filed: 1983-08-15
Abstract: PURPOSE:To manufacture the titled sheet inexpensively, by covering thermoplastic resin A on both surfaces with thermoplastic resin B non-adhesive to the resin A, by extruding these resins together, and by separating then the layer of the resin B from the resin A. CONSTITUTION:Thermoplastic resin A (ex.: PVC, methacrylate resin, PS) is covered on both surfaces with thermoplastic resin B (ex.: low-density PE in the case when the resin A is hard PVC), and in this state, these resins are extruded together into a sheet. Thereafter the exterior thermoplastic resin B is separated from the resin A, and thereby a sheet virtually free from optical anisotropy can be obtained simply and inexpensively. The ratio of A to the total thickness of the sheet extruded together is preferably less than 90%, and when said ratio exceeds 90%, the optical anisotropy sometimes occurs undesirably. The above-stated sheet virtually free from the optical anisotropy is protected from the sticking of foreign particles etc. in the processes of production, conveyance, cutting, etc., since it is covered with the sheets of the resin B when manufactured, and thus it is advantageous, in particular, when it is used for a field of an optical recording material for an optical disc apparatus etc. which tends to be much impaired by foreign particles.

Abstract: PURPOSE:To improve an eyeball motion analyzing system and accomplish labor- saving of the system by automatically estimating the horizontal and vertical angles of an eyeball motion by a pattern matching function from the position and shape of the cornea of an eye recorded in a videotape. CONSTITUTION:The position coordinate of a certain initial value T is taken as the center of the cornea. Subsequently, a cornea side edge image 15 expected from the center T of the cornea is drawn by a computer. After that, the actual cornea side edge 2 is searched from one point U on the exepcted side edge to determine the point N on the side edge. The distance between the points U and N is calculated, and the same operation is conducted for all points on the circular arc. An index for a certain movement is set, and the position of center T of the cornea is moved in such a manner as to reduce the value as much as possible. Finally, when the index is settled less than a threshold, the position of center of the cornea is determined. The position T approaches the position A of center of the cornea to be obtained. The horizontal and vertical angles of rotation are obtained from the obtained position A of center of the cornea by a computer.

IPC: B60G9/04
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To increase bracket mounting strength against a horizontal component force in the longitudinal direction by integrally forming a pair of front and rear leg parts extending downward in a bracket to which a damper is installed and welding the both leg parts to both of the front and rear faces in a torsion beam. SOLUTION: A bracket 5 is constructed of two plate members 50, 50 on the left and right sides. In each plate member 50, a pair of leg parts 5a, 5a extending downward are integrally formed so as to be welded to both of the front and rear faces of a stiffener 3. In this way, a horizontal component force in the longitudinal direction is received by means of the stiffener 3, that is, by means of a torsion beam 1 via the leg parts 5a even when a load tilted in the longitudinal direction works on the bracket 5. Therefore, mounting strength for the bracket 5 against a horizontal component force in the longitudinal direction can be improved. In addition, torsional rigidity of the bracket 5 can be increased when the left and right plate members 50, 50 are bent so as to be provided with projection shapes in the plane view.
