Title: Release protective sheet for hot-pressing lamination
Inventor: HATAKEYAMA MINORU
IPC: B29C43/20
Filed: 1990-11-14
Abstract: PURPOSE:To prevent the generation of a defect when multilayer circuit boards are laminated, and to improve yield on manufacture by using a porous fluoroplastic sheet between a circuit fixture board and a laminated circuit board. CONSTITUTION:Continuous porous PTFE(polytetrafluoroethylene) sheets are formed among circuit fixture boards 4 and laminated circuit boards 1, and laminated by a platen press with a vacuum chamber. A porous fluoroplastic sheet is deformed flexibly by compressive force even at the time of a low temperature, and excess pressure generated by a foreign matter and a resin piece on pressing can be absorbed easily even when there are the fine foreign matter and the resin piece between the circuit fixture board and the laminated circuit board, thus preventing the generation of an embossing die in the surface of the copper foil of the laminated circuit board, then further improving yield on the manufacture of a multilayer circuit board. Since fluoroplastics are employed, release characteristics are sufficient even in high-temperature laminating.

Inventor: KAWAZU NARIYUKI
IPC: H01M8/02
Filed: 1993-11-12
Abstract: PURPOSE:To decrease contact resistance between an electrode and a collector electrode in a fuel cell. CONSTITUTION:A plurality of ribs 42 are formed in a collector electrode 40, and a flow path 48 of positive pole fuel is formed by this rib 42 and a surface of a positive pole 20. The positive pole 20 is formed by cutting a carbon cloth, plane woven by a warp 22 consisting of carbon fiber and by a weft 24 consisting of carbon fiber, so that a side of forming the periphery of the positive pole 20 is crossed at a 45 deg. angle respectively with the warp 22 and the weft 24. Consequently, each yarn of the warp 22 and the weft 24 of the positive pole 20 is crossed at a 45 deg. angle with the rib 20, and since the yarn comes into direct contact with the rib 42, in transmitting an electron to the positive pole 20 from the collector electrode 110, the electron is transmitted directly to each yarn from the rib 42. As a result, contact resistance between the collector electrode and the positive pole 20, generated by only contact resistance between the rib 42 and the yarn, can be decreased.

Title: Crystal oscillator
Inventor: TAMURA FUJIO
IPC: H03B5/32
Filed: 1989-11-27
Abstract: PURPOSE:To reduce the exciting power of a crystal vibrator by using a resistor and a capacitor so as to drive an oscillation circuit at a voltage lower than a main power supply in a crystal oscillator comprising a CMOS inverter. CONSTITUTION:A CMOS inverter 10 acts like an amplifier with a feedback resistor 11 and they form a Colpitz oscillator circuit with a crystal vibrator 14 and capacitors 12, 13. The oscillation circuit is driven by a voltage V'dd decreased by a resistor 16. Not only the relation of V'dd<Vdd exists naturally but also the voltage Vdd, is stabilized against the voltage Vdd. Thus, the transfer characteristic of the CMOS inverter with a lower power voltage (case a) is steeper than that with a higher power voltage (case b) and the gain is remarkably increased by decreasing the drive voltage V'dd of the oscillation circuit more than the voltage Vdd.
