  • Patent number: 7770176
    Abstract: According to an aspect of the present invention, the processor temperatures can be leveled among processors, thereby suppressing the occurrence of stop of processing due to overheating. For example, on the basis of the temperatures of the processors sensed by temperature sensors, the control IC assigns the processor whose temperature is the lowest to the task whose heat emission is the highest. This makes it possible to level the processor temperatures among processors and suppress occurrence of stop of processing due to overheating.

  • Publication number: 20100072046
    Abstract: A waterproof push button switch does not need to be covered with a resin to a height at which a divided connected portion of a case for the switch is hidden by the resin in a height direction and the divided connected portion may be waterproofed. A gap (55, 57) is formed between a peripheral wall portion 7b of a base case 7 and a second cylindrical wall portion 9b of a cover case 9, and between an opposite surface 41 of the cover case 9 and a waterproofing seal member 11. The gap (55, 57) extends from an opening portion of the base case fitting chamber 37 to an annular watertight seal portion 51 to completely surround a periphery of the watertight seal portion 51. The thickness of the gap portion 55 is determined so that the resin entered into the gap portion 55 from an opening portion 37a of the base case fitting chamber 37 reaches the watertight seal portion 51 by surface tension.

  • Patent number: 7497109
    Abstract: A gas sensor made up of a sensor element and a first and a second hollow cylindrical porcelain insulators covering the sensor element. The first porcelain insulator is laid on the second porcelain insulator in alignment within a body of the gas sensor. A base end surface of the first porcelain insulator is placed in abutment with a top end surface of the second porcelain insulator. At least one of the base end surface of the top end surface has a ground flat area which forms an interface between the first and second porcelain insulators without micro-contacts resulting in concentration of local stress which would lead to breakage of the first or second porcelain insulator when subjected to physical loads.

  • Publication number: 20090019225
    Abstract: With respect to memory access instructions contained in an internal representation program, an information processing apparatus generates a load cache instruction, a cache hit judgment instruction, and a cache miss instruction that is executed in correspondence with a result of a judgment process performed according to the cache hit judgment instruction. In a case where the internal representation program contains a plurality of memory access instruction having a possibility of using mutually the same cache line in a cache memory when mutually different cache lines in a main memory are accessed, the information processing apparatus generates a combine instruction instructing that judgment results of the judgment processes that are performed according to the cache hit judgment instruction should be combined into one judgment result. The information processing apparatus outputs an output program that contains these instructions that have been generated.
