  • Publication number: 20210309133
    Abstract: There are improved a vibration absorption characteristic and an impact absorption characteristic. In a suspension mechanism 1 of the present invention, first and second dampers (150, 160) are suspended in parallel between an upper frame (120) and a lower frame (110) with mounting angles different from each other. For this reason, the smaller mounting angle the damper has, the smaller a vertical component of damping force becomes, and the damping force which acts on the upper frame (120) and the lower frame (110) which move up and down relatively is moderate in effectiveness as compared with a case of disposing all the dampers at the same mounting angle. Thus, a sense of incongruity in which strong damping force acts abruptly is suppressed and the vibration absorption characteristic and the impact absorption characteristic are improved, which leads to improvement in ride comfort.

  • Publication number: 20190207865
    Abstract: An object of the present invention is to provide a content distribution service that takes into account a communication capacity limit value of a communication plan used by a user. To this end, an information processing device includes: a communication capacity limit management unit that manages a communication capacity limit value of a terminal to which a content is to be distributed, and a determination target period which is a period during which a used communication capacity is determined; a remaining communication amount calculation unit that calculates, on the basis of the communication capacity limit value, a remaining communication amount in the determination target period; a content selection unit that selects a content to be distributed according to the remaining communication amount; and a content distribution unit that distributes the selected content to the terminal.

  • Publication number: 20190172090
    Abstract: Content for distribution to a terminal device is selected in accordance with a distribution condition set to each piece of content. A comparison process between an increased gradient value of a display count and an ideal gradient value of the display count of the content selected for distribution to the terminal device is executed. The increased gradient value of the display count is a gradient value from a start of the distribution until a certain time point before an end of a distribution period. The ideal gradient value of the display count is a gradient value obtained based on a distribution period length and a target display count. The distribution condition is adjusted such that a distribution frequency of the content is varied according to the comparison result.

  • Patent number: 8806880
    Abstract: An expansion valve for reducing the quantity of material required for the valve body by contriving the arrangement of bolt fitting grooves. In the expansion valve (20), displacement of a valve member driver (36) provided in the valve body (21) is transmitted to a valve member by a valve member drive rod (36f) and the valve opening is altered to control the flow rate of the refrigerant. The valve body (21) consists of a body upper portion (40) and a body lower portion (41) narrower than the body upper portion (40), and bolt fitting grooves (43, 43) opening in the flank of the valve body (21), preferably opening obliquely downward, are formed at the boundary (42) of the body upper portion (40) and the body lower portion (41). With such a layout, the material required at the boundary (42) can be reduced furthermore and the quantity of material required for the valve body (21) can be reduced furthermore, as a result.

  • Patent number: 8453584
    Abstract: A method for handling a substance from which a combustible gas volatilizes. A method for handling a substance from which a combustible gas volatilizes, in which, when such substance is handled inside an apparatus with a high degree of hermeticity, air is introduced into the apparatus and the substance is handled in a state in which the volatilized combustible gas is diluted to a concentration at which neither explosion nor fire occurs. With this method for handling a substance from which a combustible gas volatilizes, the combustible gas is diluted with air to a concentration at which neither explosion nor fire occurs, without using inactive gases such as nitrogen or carbon dioxide that have to be produced or purchased. Therefore, a substance from which a combustible gas volatilizes can be inexpensively and safely handled in operations such as mixing and storing.

  • Patent number: 8393172
    Abstract: An heat pump drying machine has a normal dry mode (e.g., compression ratio is equal to or greater than 3) for operating a compressor at a predetermined dry operation frequency and an energy saving dry mode (e.g., compression ratio is equal to or greater than 2.3 and is less than 3) for operating the compressor at an energy saving operation frequency that is lower than the dry operation frequency. A control device is provided to control an operation frequency of the compressor 5so that the two dry operation modes are switched to each other. The control device can execute the control for increasing the operation frequency of the compressor to the dry operation frequency during the operation of the energy saving dry mode.
