Abstract: PROBLEM TO BE SOLVED: To cope with display shape and structure even when a pen is put on front side, to functionally reduce constraint, to improve an S/N ratio and to easily enhance accuracy by making a light receiving part which receives light with an input pen a taper shape. SOLUTION: Light from a semiconductor laser light source is converged into parallel light by a collimator lens that is arranged in front, further a rotational mirror surface which is fixed to a position that is preliminarily defined is irradiated with the light and the light is rotationally scanned in parallel with an input plane. A light receiving window which is arranged at the tip of an input pen is irradiated with the light that is rotationally scanned, and the light is guided by a photodetector 6, converted into an electric signal, amplified by an amplifier and inputted to a CPU. The light receiving window consists of two members that are a transparent member 7b whose conical recessed part is turned down from the bottom of a cylinder toward a center and a member 7c which slidingly writes on the input plane.  The conic recessed part of the transparent member 7b is mirror finished and efficiently guides scanning light that is reflected on a rotational mirror to the phtodetector 6.

Title: Optical fiber connector
Inventor: SUZUKI NOBUO
IPC: G02B6/38
Filed: 1980-08-26
Abstract: PURPOSE:To provide an optical fiber connector of less variance in loss owing to mounting and dismounting by constituting only the end face in particular of an optical fiber in the butt surface of a plug to a concave spherical surface. CONSTITUTION:An optical fiber 1 is mounted in the center of an optical fiber connector 2, and a butt surface 4 is worked flat and the end face of the fiber 1 to a concave spherical surface. If in connecting optical fibers the end faces of the optical fibers which are held flat are opposed by leaving a microspace, multiple reflections calls Fresnel reflections occur between the end faces of the fibers and not only the loss of connection increases owing to their interference effect but also the reproducibility of connection efficiency is uncertain owing to the variance in the space between the fibers; whereas it is possible to prevent the multiple reflections such as those mentioned above by working only the end faces of the optical fibers to a concave spherical surface because these make the optical path lengths and phases of the reflected light random.

IPC: G11C29/44
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which information on a fail address and that on a fail number can be extracted automatically by a method wherein fail-bit information is extracted from a wavelet conversion result with reference to the binary image of a fail bit map which is input. SOLUTION: A fail bit map which is input is wavelet-converted two- dimensionally. Information on a Y-direction fail bit, i.e., information on an X-direction high pass and on a Y-direction low pass containing a longitudinal component, is fetched. The wavelet factor of a wavelet conversion longitudinal- line component is integrated in the longitidinal direction, and a histogram is created. Then, the obtained histogram is scanned, an address whose integrated value is not 0 is searched, and a fail number is computed. When the computed fail number is equal to the size of the fail bit map which is input, the size of a line fail and its X-address are output as fail-bit information. When the computed fail number is smaller than the size of the fail bit map which is input, a prescribed processing operation is performed separately.

Abstract: PURPOSE: To prevent an erroneous connection by providing a squelch table with information showing a bi-direction or a one-side direction, cross connect type information, squelch information and workline information for each node. CONSTITUTION: Node faults are simultaneously generated in a node 3 and a node 2, and the relief of a transmission line is started in the node 1 and the node 11 which are adjacent to the node 3 and the node 2. The nodes 1 and 4 recognize that the nodes 2 and 3 simultaneously become the node faults by the detecting method of a faulty node. The node 4 refers to the squelch information on the WORK channel of the squelch table and retrieves whether the path communicating with the nodes 2 and 3 which become node faults exists or not. When the faulty node is discovered in an 'ADD NODE', a PATH AIS 202 is inserted into the WORK channel. When the faulty node is discovered in a 'DROP NODE', a PATH AIS 202 is inserted into an STBY channel.

Abstract: PURPOSE:To obtain a bonding apparatus which facilitates bonding free from alignment discrepancy by a method wherein a temperature detected by a temperture sensor is converted into a voltage and reference bonding coordinates inputted in accordance with the design values of an IC pattern are corrected by the values corresponding to the heat expansion of an IC chip. CONSTITUTION:A temperature, which is almost equal to the temperature on the surface of a chip, is detected by a temperature sensor 10 buried in a heating block 8 and a voltage corresponding to the detected temperature is outputted by a temperature- voltage converter 12. The outputted voltage is amplified by an amplifier 13 and inputted to an A/D converter 14. The temperature difference between the obtained heater temperature and the room temperature is calculated and, by using the heat expansion coefficient of the chip material, the discrepancy from reference bonding coordinates data caused by the heat expansion is calculated and new reference bonding coordinates data corrected by the values corresponding to the heat expansion are obtained. Based upon the new bonding coordinates data, discrepancy correction is processed by using the discrepancy of the chip obtained by pattern recognition to obtain the bonding coordinates data of the arbitrarily shifted chip and then electrodes are connected to a lead frame.
