| 20090235056 | RECORDING MEDIUM STORING PERFORMANCE MONITORING PROGRAM, PERFORMANCE MONITORING METHOD, AND PERFORMANCE MONITORING DEVICE - A performance monitoring device has an interrupt detection unit that detects generation of an interrupt process to be executed by a processor in accordance with TLB entry invalidation executed in an operating system. A counter value acquisition unit acquires a counter value of a predetermined event counted by the processor when the interrupt process is detected by the interrupt detection unit. A process information acquisition unit acquires identification information for identifying a process executed on the processor from the operating system immediately before the interrupt process is detected by the interrupt detection unit. An associating unit associates the counter value acquired by the counter value acquisition unit during the interrupt process with the identification information acquired by the process information acquisition unit immediately before the interrupt process. | 09-17-2009 |
| 20110041014 | PROGRAM STATUS DETECTING APPARATUS AND METHOD - A method for a computer including a processor that is capable of counting invalidation of translation lookaside buffers and generating an interrupt at the occurrence of the invalidation, the invalidation being performed by an operating system upon switching between application programs, includes acquiring identification information of application programs from the operating system and storing the identification information as a first list; detecting an interrupt generated from the processor at the occurrence of switching from a first application program to a second application program; and when the interrupt is detected, acquiring the identification information of the first and second application programs from the operating system or the mechanism and comparing the acquired identification information with the first list to determine whether either of the first and second application programs is a program that has been created or disappeared. | 02-17-2011 |

| 20100091216 | PHASE DELAY ELEMENT FOR TRANSMISSIVE AND REFLECTIVE TYPE LIQUID CRYSTAL DISPLAY - A phase delay element includes a brightness enhancement layer intermediate a reflection layer and an artificial light. The brightness enhancement layer is defined by a first surface and an opposite second surface. The first surface faces the reflection layer. A first light from the artificial light is incident on the second surface. A phase of the first light is delayed by about 1/4 phase (λ/4) so that a second light is emitted from the first surface toward the reflection layer. The second light is reflected from the reflection layer so that a third light is emitted from the reflection layer toward the first surface. A phase of the third light is delayed by about 1/4 phase (λ/4) so that a fourth light is emitted from the second surface. Therefore, a portion of the artificial light, which is reflected from the reflection layer, is recycled to improve a luminance of an LCD apparatus. | 04-15-2010 |

| 20090105024 | CHAIN TRANSMISSION - A hybrid chain comprises outer links composed of link plates connected in side-by-side relationship by two connecting pins fitted to holes in the outer plates, and inner links composed of link plates in spaced, side-by-side relationship and connected by two bushings on which rollers are mounted, the bushings being fitted to holes in the inner plates. The inner and outer links are connected in alternating, overlapping, relationship, with each pin of an outer link extending through a bushing of an adjacent overlapping inner link. The chain meshes with a sprocket composed of a central sprocket engaged by the rollers, and two side sprockets. The inner link plates, the outer link plates, or both, have two teeth, with outer flanks in the form of arcs each centered on the more remote pin or bushing hole. The inner link plates, outer link plates, or both, can be double-sided link plates. | 04-23-2009 |
| 20090143178 | SHOCK ABSORBING STRUCTURE IN IDLER - A shock absorbing structure in an idler in which the shock of first abutment of a roller in a roller chain in a case where the roller engages with an idler sprocket, is absorbed or reduced The structure has an idler | 06-04-2009 |
| 20090209380 | SPROCKET FOR CHAIN - A sprocket for a chain drive using a roller or bushing chain has a plurality of different pitch angles, including both pitch angles larger than the standard pitch angle, and pitch angles smaller than the standard pitch angle. The number of pitch angles in the sprocket larger than the standard pitch angle is greater than the number of pitch angles in the sprocket smaller than the standard pitch angle. | 08-20-2009 |
| 20090247340 | CHAIN TRANSMISSION DEVICE - In a chain transmission, the link plates of a roller chain or rollerless bushing chain are formed with pairs of teeth. A sprocket has a central set of sprocket teeth for meshing with the rollers or bushings, and sets of side sprocket teeth for meshing with the sprocket. The teeth of the link plates function as a silent chain. After an inner flank of a link plate tooth comes into contact with a side sprocket tooth, a roller and an outer flank of the link plate tooth are seated on the sprocket. | 10-01-2009 |
