Abstract: A server includes a content storage medium configured to store content data of content usable in different types of games up to a first upper number, and a management information storage medium configured to store valid period information of a right to use an extended function concerning the content data The server, in case that a right to use an extended function is valid, sends the content data to an information-processing device or receives the content data from the information-processing device, and stores the content data in the content storage medium up to a second upper number larger than the first upper number. The server, in case that the right is invalid, performs at least one of transmission of the content data to the information-processing device and reception of the content data from the information-processing device, in a restricted manner as compared with a case where the right is valid.

Abstract: A non-limiting example content holding system includes a game apparatus and a server, which are connected to each other communicably via a network. Multiple types of games can be played on the game apparatus, and a character used in the game can be deposited with the server. In a case of depositing a character with the server, character data is converted into a format having a common area and an inherent area of a game. When keeping the character, the server updates, in withdrawal character data of the character, only common data and data of the inherent area used in the game. When withdrawing a deposited character, the game apparatus acquires, from withdrawal character data held on the server, the character data having the common area, and the inherent area of the game that uses the character to be withdrawn, and converts the acquired character data into a format to be used in the game, and saves the converted data while including in save data.

Abstract: A server includes a content storage medium configured to store content data of content usable in different types of games. The server, upon a transmission request, sends content data to an information-processing device, and retains the sent content data in the content storage medium wherein sending the content data again is prohibited. The server, when the content data is sent from the information-processing device, receives the content data, assigns a new ID to the received content data in case the received content data lacks the ID, and stores the received content data in the content storage medium wherein sending the content data is allowed.

Abstract: A crankshaft of an internal combustion engine has journals provided with shaft oil passages for carrying the oil to crankpins, and guide grooves having parts in which the shaft oil passages open, respectively, and opening in the cylindrical surfaces of the journals, respectively. The guide grooves has downstream end parts into which the shaft oil passages open, respectively, and extend in a circumferential direction in which the crankshaft rotates from the downstream end parts, respectively. First half bearing members of bearings are provided in their bearing surfaces with oil grooves through which the oil is supplied to the guide grooves, respectively. Each of the oil grooves are diametrically opposite to each of the guide grooves. The oil grooves have an axial width (W5) smaller than the axial width (W3) of the guide grooves. Thus oil leakage from gaps between each of the bearings and each of the journals of the crankshaft is reduced and hence an oil pump having a small capacity can be used.

Abstract: There is provided a gas concentration-detecting device for detecting the concentration of gas in oil, which is capable of detecting the concentration of gas in oil with accuracy, irrespective of the temperature of oil, and even when oil is degraded. The gas concentration-detecting device includes two electrodes for being arranged in the oil such that the electrodes are opposed to each other and spaced from each other by a predetermined distance, and a capacitance amplifier for outputting a signal indicative of a concentration of gas in oil, the signal being dependent on a capacitance between the electrodes. The predetermined distance between the electrodes is set to a value equal to or larger than a predetermined value at which an amount of drift of the signal output from the capacitance amplifier dependent on variation in a temperature of the oil starts to gradually decrease as the distance between the electrodes is increased.
