  • Publication number: 20190144028
    Abstract: A synchronization signal generating portion of a transmitter microcomputer generates a synchronization signal that is synchronized with a drive timing of the own microcomputer and also causes to synchronize the drive timing of microcomputers, and transmits to a receiver microcomputer. A timing corrector of the receiver microcomputer is capable of correcting the drive timing of the own microcomputer so as to synchronize with the received synchronization signal, and includes a timing determiner which determines whether the received synchronization signal is normal or abnormal. The receiver microcomputer permits the timing correction if the synchronization signal is determined to be normal in the timing determination, and prohibits timing correction and drives the motor asynchronously with the transmitter microcomputer if the synchronization signal is determined to be abnormal.

  • Publication number: 20190137184
    Abstract: A side slit of a core plate of a heat exchanger reaches a sealing surface. The core plate has a rib which is formed on a bottom plate across a protruding portion. The rib communicates to a cavity above the sealing surface. An end slit formed on an end wall of the core plate reaches the sealing surface. A first joining tab is formed between two end slits. The first joining tab is joined to a second joining tab on a reinforce plate. The side slit and the rib enable deformation of the core plate. The end slit enables deformation of the first joining tab in a tilting manner.

  • Patent number: 9780961
    Abstract: A HEMS controller repeatedly transmits a predetermined signal to a control-target appliance at a set time interval in order to detect a change in a status of the control-target appliance. If the status changes, the HEMS controller notifies a smartphone of the changed status via a server apparatus. In a state where the time interval is set to a first time interval, when receiving a control instruction for controlling an operation of the control-target appliance from the smartphone via the server apparatus, the HEMS controller transmits the control instruction to the control-target appliance. In response to the transmission of the control instruction to the control-target appliance, the HEMS controller changes the time interval to a second time interval shorter than the first time interval.
