Patent number: 8872528Abstract: A capacitive physical quantity detector includes: a capacitor having an electrostatic capacitance changeable with physical quantity; a converter converting a capacitance change to a voltage; and a selector having a comparator and a switching element. The converter includes a C-V converting circuit having an operational amplifier for amplifying a first signal from the capacitor, a main switch between input and output terminals of the operational amplifier, feedback capacitors and feedback switches. Each feedback switch connects a feedback capacitor to the main switch when the feedback switch is closed. The selector closes the feedback switches based on a second signal of the converter. The comparator compares the second signal with a threshold voltage. The switching element switches the feedback switches according to a third signal from the comparator to set the second signal smaller than a saturated voltage and larger than the threshold voltage.Type: GrantFiled: September 6, 2011Date of Patent: October 28, 2014Assignee: DENSO CORPORATIONInventors: Hirokazu Itou, Kazuki Mikamo

Patent number: 6309485Abstract: A method and apparatus for the manufacture of laminated compact disc. When forming an adhesive layer between a first substrate and a second substrate, and laminating the first substrate and second substrate to produce a disc, temperature and other conditions are adjusted based on the adhesive layer thickness of the manufactured optical disc, thus the viscosity of adhesive is changed to match each process. Accordingly, high quality discs can be consistently manufactured, and the operating efficiency of the manufacturing apparatus can be improved. Moreover, an optical disc free of bubbles mixed in the adhesive layer of a laminated optical disc can be stably manufactured.Type: GrantFiled: December 17, 1998Date of Patent: October 30, 2001Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hisaki Miyamoto, Kiyoshi Inoue, Hirokazu Itou, Toshikazu Kozono
