  • Patent number: 9315220
    Abstract: Provided is a cab for construction machine, having an excellent operator protection effect against a lateral load. Provided is a cab disposed on an upper frame of a construction machine, including a pair of rear pillars and a rear panel disposed therebetween. The rear panel includes an outer panel and an inner panel including a plurality of panel portions vertically arranged and a bridge portion partly bridging the panel portions vertically adjacent to each other at a position offset from a lateral center position of the rear panel. The bridge portion forms a low-strength portion having lower strength than that of the panel portions so as to make the low-strength portion include a bending point at which the rear panel is bent when a lateral load acts thereon through an outer rear pillar.

  • Patent number: 8918560
    Abstract: A controller for a storage device is connected to a host system and the storage device. A buffer memory includes first and second storage areas. A timer counts a preset given time in response to an instruction to start counting and sends a deadline notification when A given time is elapsed. A command responding portion, when receiving a read command from the host system, instructs the timer to start counting and thereafter outputs a read instruction to read data from the storage system. A data processing portion, in response to the read instruction by the command responding portion, reads specified data from the storage device and holds the read data in the second storage area of the buffer memory. A read control portion sends the host system the data held in the second storage area of the buffer memory when the deadline notification is received from the timer.
