Abstract: An information processing apparatus includes: a first control device that controls, in accordance with an operation mode, power reception/delivery from/to an external device connected to the information processing apparatus; a battery that is recharged by an external power supply or the external device; a second control device that acquires a power supply state of the information processing apparatus; and a third control device that determines whether power is being delivered from the external power supply to the information processing apparatus; and sets the operation mode of the first control device to a first mode based on the power supply state and on a result of the determination. The first mode is an operation mode in which the power reception alone is enabled between the power reception from the external device and the power delivery to the external device.

Abstract: A liquid supply unit includes a first chamber, a second chamber, an opening/closing member, a biasing member, a pressing member and a flexible film member. The first chamber communicates with a liquid storage container, and the second chamber communicates with a liquid injection head. The opening/closing member changes a posture between a closing posture for closing a communication opening and an opening posture for opening it. The biasing member biases the opening/closing member in a direction toward the closing posture. The pressing member presses the opening/closing member in a direction toward the opening posture. The flexible film member is displaced based on a negative pressure generated in the second chamber. When a pressure receiving portion of the pressing member receives the displacement force from the flexible film member, the pressing member rotates about a pivot point and presses the opening/closing member against a biasing force of the biasing member.

Abstract: A liquid supply unit includes a first chamber, a second chamber, a wall portion, an opening/closing member, a flexible film member and a transmitting member. The wall portion includes a communication opening allowing communication between the first chamber and the second chamber. The opening/closing member changes a posture between a closing posture for closing the communication opening from the second chamber side and an opening posture. The flexible film member is displaced based on a pressure change of the second chamber. The transmitting member transmits a displacement force to the opening/closing member to be the opening posture when the second chamber is set to a negative pressure exceeding a predetermined threshold value, and transmits the displacement force to the opening/closing member to be the closing posture according to a displacement of the flexible film member when the second chamber is pressurized.

Abstract: A rotor core in which magnets are embedded is formed by stacking a plurality of steel sheets. Each steel sheet which has a disk shape has: six magnet insertion holes formed so as to allow permanent magnets to be inserted therein as a whole; circumferential-direction bridge portions connecting, in the circumferential direction, radially-outer-side steel sheets each formed at the peripheral part of the steel sheet, between the magnet insertion holes; and radial-direction bridge portions formed between the magnet insertion holes.

The coined portions having decreased sheet thicknesses suppress short-circuit of a magnetic flux between magnetic poles, and formation of the arc shapes absorbs extension of these portions caused by a coining work, to suppress deformation of the steel sheet.
