Title: Co detecting apparatus
Inventor: AMAMOTO TARO
IPC: G01N27/12
Filed: 1989-01-27
Abstract: PURPOSE:To improve the detecting accuracy of CO by using two factors of the gas sensor output ratio between a low temperature region and a high temperature region and the output at the lower temperature region. CONSTITUTION:This apparatus is composed of the following parts: a gas sensor 2 wherein a metal oxide semiconductor 4 is heated with a heater 6; a power source 8; a power source 10 having two outputs V1 and V2; a signal processing microcomputer 12; a driver 32 which is operated by the output of the microcomputer; a light emitting diode 34 which is controlled by the driver; a buzzer 36; and a fuel shut-off valve 38. The sensor 2 is operated for one period (60 seconds in a high temperature region and 90 seconds in a low temperature region). The electric conductivity immediately before the end of each temperature region is obtained. The presence or absence of CO can be judged by using the output ratio. The detecting accuracy of the CO can be improved by using the independent factors of the output ratio and the output in the low temperature region.

Inventor: YAMAGUCHI NOBUTAKA
IPC: G11B5/127
Filed: 1986-01-30
Abstract: PURPOSE:To improve the surface performance of a coated film by forming said coated film containing the polishing agent made of chromium oxide and the bonding agent made of vinyl chloride-vinyl active-vinyl alcohol onto a nonmagnetic supporting body, thus permitting the sufficient polishing without damaging the tape sliding surface of a magnetic head. CONSTITUTION:A polishing tape is constituted of a nonmagnetic supporting body 1 and a coated layer 2 formed onto the supporting body 1. Said coated layer 2 contains a polishing agent 3 and a bonding agent, and said polishing agent 3 consists of the polishing particles made of chromium oxide having a Mohs' hardness of 8.5 or so, and the bonding agent is made of vinyl chloride- vinyl acetate-vinyl alcohol. Therefore, the tape sliding surface of a magnetic head 4 can be smoothly polished without damaging the tape sliding surface by the polishing agent 3 having a proper hardness. Further, since only vinyl chloride-vinyl acetate-vinyl alcohol as three component copolymer having the superior dispersion performance is used as bonding agent, said polishing agent can be uniformly dispersed into the coating liquid, and the surface performance of the coated film can be improved.
