Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To prevent contamination of the stencil back side due to cobwebbing at the release operation by providing means for setting the release speed, distance and stop time at the release position as desired. SOLUTION: A bed 6 has a speed control 7 for setting the lowering speed of a table 4 and a screw shaft 5 by turning to desired position for specified lowering speed. The bed has a distance indicator 8 erected near the outer side edge of the table 4 so that a cursor 9 for selecting the lowering position of the table 4 can be restricted at a desired moving position in the axial direction. The cursor has a detector electrically coupled with a stop time adjusting timer 10 to thereby stop the table 4 at a release position for the specified time. Thus it is possible to manufacture a semiconductor device in optimum conditions.

IPC: G01S19/07
Filed: 1993-06-15
Abstract: PURPOSE:To achieve higher accuracy by detecting a deviation value at a fixed station to correct positional information calculated at a moving station utilizing the results. CONSTITUTION:A fixed station transmits a deviation value as determined by comparing a position data of a fixed station as calculated based on radiowave information from a satellite to a reference position data by an FM radiowave. On the other hand, in a satellite receiving circuit 8 of a moving station, radiowave information from the satellite as received by a receiving antenna 1 is processed by a signal processing circuit 5. An information recognizing circuit 26 judges it to be good or bad that satellite information supplied from a second demodulation circuit 25 should be supplied to an arithmetic processing circuit 30. To achieve this, a satellite number form the processing circuit 5 is compared with that from the demodulation circuit 25. When they coincide, the recognition circuit 25 supplies the satellite information from the fixed station to the processing circuit 30. The processing circuit 5 corrects positional information calculated by the processing circuit 5 to be outputted as position data through an output interface circuit 7 by the satellite information as reference.

Title: Electrode and secondary battery using this electrode
Inventor: MATSUDA YOSHIO
IPC: H01M4/525
Filed: 1993-06-15
Abstract: PURPOSE:To enhance discharge capacity, especially cycle life by using a carbonaceous material as a conductor and by limiting the crystallite diameter of the carbonaceous material in a specified range. CONSTITUTION:Artificial graphite serving as a conductor relatively widely changes the volume by a doping/undoping phenomenon which means that an anion of an electrolyte is doped into a conductor (artificial graphite) of a positive electrode on charging and undoped on discharging. Adhesive between the positive active material and the conductor is decreased to increase contact resistance. As a result, overvoltage is increased and discharge capacity is decreased with charge/discharge cycles, or cycle life is decreased. To prevent the problem, the conductor is changed to a carbonaceous material with a crystallite diameter Lc of 10Angstrom <=Lc<=40Angstrom . A lithium composite oxide selected from LixCoO2 (0<x<=1.0), LixNiO2 (0<xH1.0) and others is used as the positive active material. Cycle life is lengthened.
