A memory access control device includes: a memory configured to hold data from a host device; and a processor coupled to the memory, the processor: detects an overlapping portion of addresses of data transfer sources of a plurality of memory access requests; merges, in a case where the overlapping portion is detected, read accesses to the data transfer sources for the overlapping portion of the plurality of memory access requests collectively to generate a merged memory access request; executes a data transfer in accordance with the merged memory access request; and instructs writing of data transferred in the data transfer to a plurality of addresses of data transfer destinations of the plurality of memory access requests.

Memory access control device and control method of memory access

A memory control apparatus, in a case of receiving from a processor, under a condition where the number of cache memories retaining a copy of data stored in a main storage device is one, a notification to the effect that data retained in the cache memory is purged, updates directory information on a directory cache without accessing the main storage device when the data is not modified by the processor, and the directory information on the directory cache and directory information on the main storage device is determined to be different and the directory information on the main storage device is determined to be in a state indicating that the copy of the data is not retained by any processor in the state of coherence.

Information processing apparatus and memory control apparatus

A device for selecting vehicles to be sent to a site of a fire is provided. The device includes a storage unit provided with a vehicle table and a fire-spreading condition table. Fire-extinguishing ability data and arrival time data for each vehicle are stored in the vehicle table as numerical data. Initial fire power data and fire-spreading rate data are stored in the fire-spreading condition table as numerical data. The device also includes a vehicle organizing part deriving a relationship between total fire-extinguishing ability of vehicles and total fire-spreading power of the fire with respect to time, and selecting vehicles to be sent to the fire site based on the relationship.

Device, method and system for selecting emergency vehicles

A hydraulic damper includes a cylinder containing hydraulic fluid therein, a piston working in the cylinder and partitioning the interior thereof into two liquid chambers, a piston rod connected to the piston and extending through one of the liquid chambers to project to the outside of the cylinder, and disc valves provided on opposite sides of the piston for generating damping force both in the extension and contraction strokes of the damper. A liquid passage is formed in the piston rod to communicate the two liquid chambers separately from the disc valves. An adjusting member is provided in the liquid passage and is displaceable between three or more adjusting positions for changing the effective area thereof. A digital encoder connected to the adjusting member for detecting the adjusting positions. The digital encoder includes a common electric line which ON-OFF controls at least two other electric lines when the other two lines generate the same digital signals.

Hydraulic damper

A vehicle leveling system is disclosed having an air compressor adapted to issue pressurized air, a tank communicated with the compressor through an electromagnetically operated valve, and a suspension disposed between a chassis and a vehicle axle and having an air chamber to which the tank and the compressor supply the pressurized air through an electromagnetically operated valve.

Vehicle leveling system

A vehicle height adjusting device includes an air compressor, an air tank storing pressurized air produced in the air compressor, a dehumidifying device provided between the air compressor and the air tank, and an elevating device for elevating or descending the height of a vehicle and receiving pressurized air from the air tank or from the air compressor in elevating the height of the vehicle and exhausting pressurized air therefrom through the dehumidifying device to atmosphere in descending the height of the vehicle. There are provided a pressure detector detecting the pressure in the air tank, a height detector detecting the height of the vehicle, and a controlling circuit connected to the pressure detector and the height detector for controlling the operation of the elevating device in accordance with the output signal of the height detector and that of the air compressor in accordance with the output signals of the pressure detector and the height detector.

Vehicle height adjusting device

A vehicle height detecting device including a casing mounted on a body of a vehicle, a rotatable member rotatably disposed in the casing, a link arm connected with the rotatable member and with a member associated with a road wheel of the vehicle, and a detector provided in the casing for detecting the angular position of the rotatable member with respect to the casing. A retaining device is provided in the casing and is selectively engageable with the rotatable member at a predetermined angular position thereof.
