Title: Nonaqueous electrolyte secondary battery
Inventor: SAKAGUCHI TAEKO
IPC: H01M10/0568
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To improve cycle characteristics, by suppressing degradation of a nonaqueous electrolyte caused by decomposition of a solvent in a nonaqueous electrolyte secondary battery. SOLUTION: A nonaqueous electrolyte contains a specific chain ether expressed by a chemical formula, Cn F2n+1 -O-Cm H2m+1 (where, n is 1 to 5 and m is 1 to 4). In this battery, the nonaqueous electrolyte having the chain ether added thereto is used and the reduction of its discharge capacity arising during charge/discharge cycles is suppressed. In other words, the contact of a negative electrode with solvent molecules is eliminated by forming stable coatings of good quality on surfaces of the negative electrode owing to the addition of the chain ether, and therefore a solvent is stabilized, that is, the degradation of the nonaqueous electrolyte is prevented.

Title: Voltage detector
Inventor: AOSHIMA SHINICHIRO
IPC: G01R19/00
Filed: 1987-05-31
Abstract: PURPOSE:To accurately measure the voltage of an object body by an electrooptic material which is affected by the voltage of the object body and an electrooptic material for compensating a phase difference due to natural double refraction. CONSTITUTION:A light beam from a polarizer 54 is incident on the electrooptic material 21 through a beam splitter 56. The polarization state of the incident light incident on the material 21 changes with the phase difference due to the natural double refraction and the light is incident on the electrooptic material 22 from the material 21. The materials 21 and 22 are equal in length in the optical axis direction to each other, so the polarization state of the incident light incident on the material 22 changes according to the phase difference due to the natural double refraction, but changes in the opposite direction from it in the material 21, so their polarization states cancel each other. The polarization state when the incident light reaches a reflecting mirror 24 has only a change corresponding to the variation in the refractive index of the material 22 based upon the voltage at the specific part of the object body, so the voltage of the object body is accurately detected.

Title: Coordinate correction for visual recognition device
Inventor: HOSOI MASAHISA
IPC: G06T7/00
Filed: 1987-05-30
Abstract: PURPOSE:To treat the coordinates of a common recognition object as a same coordinate by obtaining a correction equation for the recognition coordinate of a visual recognition device and the coordinate on the coordinate system of a positioner for a recognition object and allowing two coordinate systems to coincide by connecting the factor and inclination of the coordinate between two coordinate systems. CONSTITUTION:A mark 18 for position recognition (recognition object) is shifted to three positions by a robot (positioner) 2 according to the instruction of a control part 3, and an image is taken three times by a camera (visual recognition device) 5, and said image is recognized by an image recognizing part (visual recognition device) 6 and sent into the control part 3. Then, the factor and inclination of the coordinate of the camera 5 are corrected. Since each coordinate of the camera 5 and the robot 2 at three positions on the image is recognized, and since the coordinate of the mark 8 on the robot 2 is recognized by the positioning in the initial time, the correction equation for correcting the factor and inclination of the coordinate of the camera 5 and robot 2 through the coordinate transformation such as affine transformation can be obtained.

Abstract: PURPOSE: To improve the S/N ratio, by constituting a head with an amorphous thin film Hall element consisting of an alloy including rare earth element and transition  metal and with a ferromagnetic substance block clipping this.  
     CONSTITUTION: A thin film insulation layer 12 is formed on a ferromagnetic substance substrate 10 of the 1st core half piece, and a thin film 14 of GdCo etc. is  formed with vapor deposition on it. Gd or the like is used as the rare earth element, and the ratio of the components is taken as 40% or less to form an easy magnetizing axis vertical to the film surface. A ferromagnetic substance block 24 of the 2nd core half piece is fitted to it so that the Hall element 15 is clipped and it is contained in a head block 26 through depression. Thus, current noise due to crystal grain field can be reduced because of amorphous thin film 14.

Filed: 1991-06-10
Abstract: PURPOSE:To automatically attain a charge immediate notice service to a subscriber without intervention of an operator or a charge guide person. CONSTITUTION:A call processor (CP) 1 calculates a talking charge of a subscriber A registered in advance and stores it to a memory. After the end of talking, it is called to the subscriber A via a local controller (LOC) 3 and a subscriber circuit (LC) 2 to send a call signal from a ringing source (RING) 10. Succeedingly, the charge information talked just before the subscriber A stored in the memory is sent to a signal sending circuit (SND) 5 via a signal sending controller (SNDC) 6. The SND 5 converts the charge information into a digital FSK signal and sends the signal to the subscriber A via a time division network (TDNW) 4. The digital charge information is converted into an analog in-band signal by the LC 2 and received by an adaptor for charge notice (ADP) 1 and displayed.

Title: Production of prepreg
Inventor: IKETANI KUNIO
IPC: C08L63/02
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To minimize the generation of resin powder to thereby reduce defective moldings due to the powder in laminating and multilayer molding by impregnating base glass fibers with an epoxy resin varnish, cutting the prepreg to a necessary size, and treating the cut sections of the prepreg with a liquid that does not dissolve the epoxy resin and then with a liquid that dissolves the resin. SOLUTION: Water is preferably used as the liquid that does not dissolve the prepreg. It is effective to use water containing little ionic impurities particularly from the viewpoint of electrical reliability. An organic solvent (e.g. acetone) is suitably used as the liquid that dissolves the prepreg. Heating at 100 deg.C or higher is not necessary for drying. It is desirable to blow hot air at 90 deg.C or lower for drying to shorten the time of liquid treatment steps. This technique gives a prepreg which is most suitable for multilayer molding of an article flat all over the surface, without occurrence of ruggedness and waviness, and which scarcely generates resin powder from the cut sections, etc.
