Abstract:
In a magnetic heat pump system, in which heat transport medium is heated or cooled by magnetocaloric effect material accommodated in a magnetic heat pump device. A material having a coefficient of thermal conductivity, which is higher than that of the heat transport medium, or a material having a specific heat or a volume specific heat, which is higher than that of the heat transport medium, is mixed in the heat transport medium. A coefficient of thermal conductivity of the heat transport medium is thereby increased so as to increase heating and/or cooling performance of the magnetic heat pump system.
Abstract:
In order to reduce power consumption and shorten the waiting time until printing, the PC, controlling the MFP that is maintained in a sleep mode instead of being switched to a standby mode when a print job having a printing method set to confidential printing is received while it is in the sleep mode, includes a setting accepting portion to accept setting for printing, a job generating portion to generate a print job based on the accepted setting, a job transmitting portion to transmit the generated print job to the MFP, and a command transmitting portion to transmit a wake-up command to switch the MFP to the standby mode when the setting of the confidential printing as the printing method is accepted and when there is a wake-up instruction.
Abstract:
A circuit for counting a number of cycles, including: a current detecting portion that detects a current value of a current flowing to a secondary battery; a current integrating portion that calculates, as an integrated electric quantity, an integrated value of the current value detected by the current detecting portion; a cycle electric quantity setting portion that successively sets a cycle electric quantity corresponding to one cycle of a cycle life of the secondary battery; and a cycle counting portion that counts a number of cycles of the cycle life, wherein the cycle counting portion adds one to the last counted number of cycles when an increment of the integrated electric quantity calculated by the current integrating portion after the number of cycles is counted last time reaches a last set cycle electric quantity, and the cycle electric quantity setting portion decreases a predetermined decrement from the last set cycle electric quantity to set a new cycle electric quantity when the increment of the integrated electric quantity calculated by the current integrating portion after the number of cycles is counted last time reaches the last set cycle electric quantity.
Abstract:
A Multi-Function Peripheral (MFP) is provided with a locked mailbox bin. The MFP receives a print job, calculates a print quantity for a case in which the received print job is executed. If the calculated print quantity for the print job is more than a predetermined quantity, the MFP executes printing based on the print job with the locked mailbox bin designated as an output destination of a printed material. If the calculated print quantity for the print job is equal to or less than the predetermined quantity, the MFP stores the print job in a storage portion.
Abstract:
A hermetical stopper used for liquid receptacles made of aluminum including minicasks of beer. Unlike the case in conventional receptacles in which the discharge ports usually have been hermetically sealed with aluminum as the same material for the main body, the hermetical stopper according to this invention is made independently of the main body so as to be able to put into and pull from out the discharge port at will, so that it is possible to be used repeatedly keeping the hermetically sealed state even after the primary use because of the discharge port being not necessary to be cut off purposely from the main body at the time of broaching the receptacle. In this way, this hermetical stopper according to the invention is very commendable also from the point of view of the effective use of resources.
Abstract:
A magnetic heat pump cycle has a first to a fourth steps, which are repeatedly carried out. In the first step, a movement of heat medium is stopped by a pressure valve and a pressure accumulating tank and a magnetic field is applied by a magnetic-field control unit to a magnetic working material. In the second step, the pressure valve is opened so that the heat medium flows in a working chamber from a second axial end to a first axial end, and the magnetic field is increased depending on a moving speed of the heat medium. In the third step, the movement of the heat medium is stopped and the magnetic field is decreased. In the fourth step, the heat medium is moved in a reversed direction and the magnetic field is decreased depending on the moving speed of the heat medium.
Abstract:
A magneto-caloric effect type heat pump apparatus includes a magneto-caloric element which generates heat when an external magnetic field is applied to and which absorbs heat when the external magnetic field is removed from; a magnetic field switcher which switches the applying and the removal of the external magnetic field from each other; a pump pumping a heat transport medium between a low-temperature end and a high-temperature end of the magneto-caloric element; and an auxiliary heat source device which supplies heat of a heating element to the magneto-caloric element.
Abstract:
A charge control circuit includes a charge control unit that controls an operation of a charging unit that charges a rechargeable battery; and a voltage detection unit that detects a terminal voltage of the rechargeable battery, wherein when a terminal voltage of the rechargeable battery as detected by the voltage detection unit is lower than a predetermined first threshold-value voltage, being lower than a full-charge voltage which is a terminal voltage of the rechargeable battery in full charge, the charge control unit causes a constant current charging to the rechargeable battery by requesting the charging unit to supply a charging current of a predetermined first current value, causing the charging unit to supply a charging current of the first current value to the rechargeable battery, when the terminal voltage of the rechargeable battery as detected by the voltage detection unit exceeds the first threshold-value voltage but is less than the full charge voltage, the charge control unit causes the constant current charging to the rechargeable battery by requesting the charging unit to supply a charging current of a second current value that is smaller than the first current value, causing the charging unit to supply a charging current of the second current value to the rechargeable battery, and when the terminal voltage of the rechargeable battery as detected by the voltage detection unit is equal to or greater than the full charge voltage, the charge control unit causes a constant voltage charging to be carried out by causing the charging unit to supply the full charge voltage to the rechargeable battery, as a charge voltage.
