Publication number: 20180266683Abstract: A flame detection adjusting portion adjusts a preset reference threshold value based on a sensor output indicating disturbance light obtained from a flame sensor before an ignition attempt in combustion equipment and outputs an obtained adjusted threshold value, and a combustion flame detecting portion detects a presence or an absence of a combustion flame in the combustion equipment based on the sensor output obtained from the flame sensor during combustion in the combustion equipment and an adjusted threshold value.Type: ApplicationFiled: March 15, 2018Publication date: September 20, 2018Applicant: Azbil CorporationInventors: Takeshi NISHIYAMA, Yuichi KUMAZAWA, Shigeki ISHII, Akira YAMADA, Satoru YAMAGISHI, Tomoya NAKATA, Kayo SUZUKI

Publication number: 20180266682Abstract: A pseudo flame detecting portion detects a presence of a pseudo flame due to disturbance light when a sensor output of a flame sensor is equal to or greater than a pseudo flame threshold value and detects an absence of pseudo flame when the sensor output is equal to or less than another pseudo flame threshold value. The combustion controlling portion monitors the pseudo flame detection result from the pseudo flame detecting portion before an ignition attempt in the combustion equipment and, when the pseudo flame detection result continuously indicates presence of pseudo flame for a first monitoring time, cancels the ignition attempt in the combustion equipment.Type: ApplicationFiled: March 15, 2018Publication date: September 20, 2018Applicant: Azbil CorporationInventors: Takeshi NISHIYAMA, Yuichi KUMAZAWA, Shigeki ISHII, Akira YAMADA, Satoru YAMAGISHI, Tomoya NAKATA, Kayo SUZUKI

Patent number: 5555983Abstract: A cash transaction apparatus includes a plurality of storage safes for storing banknotes for each denomination. Each of the storage safes has a temporary stacking section for temporarily and removably stacking the banknotes, and a receiving section for receiving the banknotes from the temporary stacking section. Upon collecting the banknotes from at least one designated storage safe, the banknotes of the storage safe are supplied from its corresponding receiving section to an inspecting section through a dispensing-banknote conveying path, and counted therein. After that, the banknotes are stacked in a temporary stacking section corresponding to the designated storage safe, and then removed therefrom by an operator.Type: GrantFiled: September 21, 1994Date of Patent: September 17, 1996Assignee: Kabushiki Kaisha ToshibaInventor: Satoru Yamagishi
