To provide a sliding member that exhibits excellent durability and is free of lead. A swash plate for a compressor as the sliding member of the invention contains a base material having on the surface thereof a sliding layer constituting at least a sliding surface, on which shoes slide. The sliding layer contains a first layer that contains an amorphous hard carbon (diamond-like carbon) film containing Si (DLC-Si film) and is formed on the base material, and a second layer that is formed on the first layer and contains polyamideimide (PAI) containing a solid lubricant such as MoS2.

摘要:
Disclosed is an EPDM composition for molding sealing materials, containing a plasticizer; the plasticizer being a paraffinic oil or naphthenic oil in which the absolute value of the difference between its SP value (solubility parameter; determined by Small's formula) and the SP value of EPDM is 0.3 (cal/cm3)1/2 or less; and the composition being free of an ether ester plasticizer. The EPDM composition for molding sealing materials has the following excellent effects. Because a paraffinic oil or naphthenic oil that is compatible with EPDM and has an absolute value of the difference between its SP value and the SP value of EPDM of 0.3 (cal/cm3)1/2 or less is used as the plasticizer, a peroxide crosslinked product of the EPDM composition does not form defects that cause the starting point of blisters even when it is subjected to extraction by being brought into contact with HFO-1234yf. Accordingly, the peroxide crosslinked product, when used as a sealing material, particularly a compressor sealing material, exhibits excellent blister resistance to a hydrofluoroolefin refrigerant, such as HFO-1234yf.

摘要:
A charge control device including: a charge control unit configured to select a power storage device to be charged from a plurality of power storage devices in accordance with degrees of subsequent deterioration of the power storage devices, the degrees being calculated based on battery information of the power storage devices each having a secondary battery; and a transmission unit configured to transmit a charge command to a power storage device selected by the charge control unit.
摘要:
A signal transfer device includes an interface and a read and write circuit. The interface has a posted write data protocol and transfers data to a memory control device that controls access to a shared memory. If a write request for writing data to the shared memory via the interface is issued, the read and write circuit acquires a write address from the write request, and puts a read request for reading data from the write address on standby until a transfer amount of write data exceeds a total size of buffers on a signal transfer path to the shared memory.

Provided is a communication device that facilitates hearing even in an environment in which hearing of sound is difficult only with air conduction sound, and requires fewer components, facilitates implementation. The communication device 100 includes: a protecting panel 101 serving as a contact member disposed at a position at which at least a part of the contact member is brought into contact with a user's ear and/or a human body around the ear; and an transducer 111 surface joined to the protecting panel 101, and configured to vibrate in a frequency band of an audible range such that vibration is not conducted from the protecting panel 101 to an auditory organ of the user via bones of a skull of the user.
摘要:
Disclosed is an input device for a capacitive touch panel, which is an input device for inputting the position on the touch panel by making the input device contact with the touch panel, including an insulating layer (11) having flexibility and optical permeability, and a conductive layer (12) having optical permeability and laminated onto the insulating layer (11), and the input device (10) is integrally formed into a cylindrical shape so that the insulating layer (11) and the conductive layer (12) become a portion to be contacted with the touch panel. Thereby, users less likely to have a sense of wear and tear of fingers, the position pointed by the input device on the touch panel is precisely recognized with ease, the accuracy of the position detected by the touch panel is improved, and input means is less likely to be lost though the input device is lost.
摘要:
If the size of an error portion within an image of the frame of interest is equal to or larger than a threshold and it is determined that no error portion exists within an image of a frame immediately before the frame of interest, a display unit (115) is caused to display the image of the frame immediately before the frame of interest as the image of the frame of interest. If the size of an error portion within the image of the frame of interest is smaller than the threshold and it is determined that an error portion exists within the image of the frame immediately before the frame of interest, the display unit (115) is caused to display a result obtained by correcting the error portion within the image of the frame of interest using a pixel group surrounding the error portion.
