Title: Superconductor
Inventor: YUZURIHARA HAJIME
IPC: H01L39/02
Filed: 1990-08-06
Abstract: PURPOSE:To prevent mutual interference between silicon or GaAs and a superconducting oxide in a superconductor by piling up an Si or GaAs substrate, oxide base layer having a specific composition, and superconducting oxide layer in this order. CONSTITUTION:An Si or GaAs substrate, oxide base layer of V2O5, and superconducting oxide layer are piled up in this order. The film thickness of the oxide base layer is set to 200Angstrom  to 1mum, preferably, 500-2,000Angstrom  and that of the superconducting layer is set to 1,000Angstrom  to 1mum, preferably, 1,000-4,000Angstrom . It is the most preferable to use a single crystal for the substrate and to use a crystal plane of (111), (100), or (110). It is desirable to form the superconducting thin film by epitaxial growth on the base layer and, accordingly, V2O5 is used for the base layer. The V2O5 is a rhombic crystal having a lattice constant and crystal structure of a = 11.52Angstrom , b = 3.56Angstrom , and c = 4.37Angstrom . The electrical resistivity of the base layer is about 1X10<5>OMEGA.cm at 100K, indicating a temperature dependency of a semiconductor in electric resistance.

Title: Thickness-measuring apparatus of semiconductor wafer
Inventor: SUGIMOTO IHEI
IPC: H01L21/66
Filed: 1990-08-09
Abstract: PURPOSE:To prevent that the stage of a probing device is contaminate and damaged, that a measuring system breaks down when the ink of a marker is dripped and that a thickness is recognized erroneously as an adjacent chip by a method wherein, when the thickness is detected as zero, it is prohibited that a defectiveness signal is applied to a marker means. CONSTITUTION:The thickness of a semiconductor wafer 1 is measured at a thickness-measuring part 3. When the thickness is zero, i.e., when a chip has a hole, a defectiveness signal and a zero detection signal are generated by a defective thickness judgment circuit 4 and a zero thickness detection circuit 7. The signals are applied to a prohibition circuit 8; it is prohibited by the zero detection signal that the defectiveness signal is sent to a driver circuit 5. Consequently, a marker 6 is not actuated for a defect caused by a hole. Even when the defective thickness judgment circuit 4 judges a thickness to be defective and the defectiveness signal is sent, the zero detection signal is not sent from the zero thickness detection circuit 7 as long as the zero thickness detection circuit 7 does not detect a zero thickness. As a result, the prohibition circuit 8 does not execute a prohibition action. Consequently, the defectiveness signal drives the marker 6 and the marker 6 puts a bad mark.

Title: Radio frequency data communication network for exchanging digital information signal
Inventor: RICHIYAADO NOOMAN AMESU
IPC: H04W84/10
Filed: 1992-07-15
Abstract: PURPOSE: To improve the overall efficiency of the network by integrating a means to select dynamically one optimum channel from a plurality of base stations to each terminal, in order to make communication via a radio-frequency channel. CONSTITUTION: A message given to a down-ring is applied to a terminal level 103 of a network from a host computer 110, and an up-ring message is given from the level 103 to a conventional communication controller GCC 101 and the computer 110. When the GCC 101 stores terminal/base station pair ID information carried by a given valid packet, the GCC 101 dynamically maintains a power request for a current terminal multiple address communication 104 with respect to the terminal/base station pair, based on the packet information. New power request information which is considered to cause a change by a radio wave state and a geographical condition is transferred to an up-ring by a revision packet. Thus, the processing capability of a down-ring system is maintained optimally.

Title: Flash photographing device
Inventor: TANIGUCHI NOBUYUKI
IPC: C09D175/04
Filed: 1982-11-29
Abstract: PURPOSE:To obtain proper exposure even for a slave object by performing exposure control which provides exposure less than an exposure control value determined by the output of an averaged photometric means by the amount of exposure corresponding to a signal with a specific value, and stopping light emission when the integral value of reflected light from an object attains to a specific value. CONSTITUTION:An averaged light metering circuit BDO measures the mean value of object brightness and outputs a photometric signal Bv. A constant value signal output circuit FXD2 outputs a constant value signal k1 corresponding to the photometric sensitivity distribution of the circuit BDO. An adding circuit ADD3 inputs signals from circuits BDO and FXD2 and from a film sensitivity output circuit SS to perform arithmetics. The arithmetic result is compared CMP2 and the comparison result is supplied to a camera-side light emission control circuit FTT. The circuit FTT is equipped with a photodetector which photodetects reflected light from a film surface and the integration of the output current of the photodetector is started on the basis of a light emission start signal generated by the closure of an X contact SX; when the integral value attains to a specific value, the light emission of a strobe device FL is stopped. Thus, not only a main object, but also a slave object are exposed properly during flash photography.

Title: Controlling method of wire rod winding-up device
Inventor: UMETSU KAORU
IPC: B21C47/14
Filed: 1982-11-29
Abstract: PURPOSE:To control a falling position of the tip of a wire rod correctly in high speed rolling by finding the difference of distance from an estimated position of wire rod discharge end to a falling controlling position and the distance from the estimated position to the actual falling position of a laying type winding-up device and correcting the next falling controlling position. CONSTITUTION:When P1 represents the estimated position of wire rod discharge of the laying pipe of the laying type winding-up device, rotation of a laying cone is shifted by S1 to make the falling control position P2. Then, actual falling position P3 is determined. At this time, since the distance from P1 to P3 is the actual amount of shifting, S1-S2 becomes the difference between estimation and actual result. Accordingly, the next controlling is corrected basin on this difference.

Title: Solder feeding method
Inventor: ARAKAWA KATSUHIRO
IPC: H05K3/34
Filed: 1992-08-06
Abstract: PURPOSE:To feed solder locally with high accuracy by adhering solder to the lead part of a tape carrier formed in the same shape as the connecting pattern of a circuit board. CONSTITUTION:A tape carrier having the same leads 4 as connecting pattern is obtained by adhering solder 5 to the leads 4 through plating or solder dipping. Supplied solder is cut and mounted through a mounter for electronic component 1, for example, onto a circuit board 2 with high accuracy. The supply solder is temporarily bonded through adhesive 6 in order to prevent movement. The electronic component 1 is then mounted thereon and an electrode 7 on the electronic component side is connected through thermal press. When the component and the supply solder are connected at first, thermal steps in connection process increase but a problem of alignment accuracy due to warp of the tape carrier can be solved. This method feeds the circuit board with solder highly accurately and realizes highly reliable mounting of electronic component 1.
