摘要:
To start up an operating system (OS), CPU performs initializations in three modes: The three modes include a first I/O initialization (Early init) (132) which is to be done serially when no threads are yet usable, without any advanced technique and with a long wait time until a next operation can be made; a second I/O initialization (136) which is to be done when threads are usable, in a plurality of steps parallelized with each other using the usable threads according to the dependency relation between devices to be initialized and with synchronization between the steps each by a barrier; and a third I/O initialization (Lazy init) (140) in which remaining initializations are done in parallel with each other using the threads commensurately to a user process when the user process becomes executable. The present invention is applicable to home-use electric or electronic appliances.
摘要:
A process scheduling apparatus has a delayed task handling process for processing delayed tasks having variable priorities and multiple other processes for handling processes other than delayed tasks. Fixed priorities are assigned to the other processes. The process scheduler sequentially executes the delayed task handling process and the other processes according the assigned priorities. A delayed task registration processor stores newly generated delayed tasks with assigned priorities in a queuing table. A delayed task priority controller selects the delayed task with the highest priority in the queuing table. A process priority controller sets the priority of the delayed task handling process to the same priority as the priority of the delayed task with the highest priority.

In the present invention, a computer in which a plurality of programs are executed under a management of an Operation System having a memory management mechanism includes a unit for ensuring atomicity of a first user process without requiring a dedicated CPU instruction. The unit for ensuring atomicity includes a unit for detecting an interrupt by a second user process, a unit for canceling the first user process by utilizing a memory protection function possessed by said Operating System, and a unit for executing an operation of the first user process again.

Rubber rollers for carrying media, comprising a blend of urethane rubber and silicone rubber, and an apparatus equipped therewith. A rubber roller abrasion evaluating tester provided with means for carrying a medium to be carried while in contact with rubber rollers to be evaluated, and means for forcefully causing slippage of the carried medium by a prescribed distance on the rollers. A method of selecting a medium to be carried which has a prescribed abrasive strength, by abrading a carried medium under a constant weight using an abrading material and calculating the rate of the abrasion of the carried medium.

A wireless sensor system according to the invention has a wireless sensor device for detecting something and a wireless base station for exchanging data with the wireless sensor device by wireless. The wireless sensor device 2 has a sampling signal transmitting portion for transmitting a sampling signal, and the wireless base station has a sensitivity detecting portion for detecting a receive sensitivity of the sampling signal, and a sensitivity transmitting portion for transmitting a result detected thereby to the wireless sensor device. And, the wireless sensor device has at least one of a LED and a buzzer for informing of the receive sensitivity on the basis of data from the sensitivity transmitting portion. A worker who tries to locate the wireless sensor device can easily know the best place for location with the LED or the like.
摘要:
An integral cast-iron connecting rod blank having a smaller-diameter end, a shank, and a larger-diameter end with a crank opening is set on an inclined base, and the tip end of a laser beam applying device is positioned in the larger-diameter end. While a YAG laser beam from the laser beam applying device is being applied to diametrically opposite inner central wall regions of the larger-diameter end, the laser beam applying device is moved to form notches transversely in the respective inner central wall regions. Two spreading elements are placed in the crank opening, and then a tapered wedge is inserted downwardly between the spreading elements. A downward impact point load is applied to a load bearing surface of the wedge thereby to apply spreading forces to the larger-diameter end. A crack starting radially outwardly from the notches is developed in the larger-diameter end, dividing the larger-diameter end into a saddle and a cap. Mating surfaces of the saddle and the cap have interfitting surface irregularities which prevent the saddle and the cap from being combined in wrong orientations. Before the larger-diameter end is split open, the crank opening is finished for roundness while the larger-diameter end is being subjected to the same load as a fastening load by which the saddle and the cap will be fastened by bolts.
