Abstract:
Herein disclosed is an optical disc driving apparatus adapted to selectively drive two kinds of optical discs different in diameter from each other to reproduce information recorded in the optical disc while reading out information in the optical disc. The optical disc driving apparatus comprises: a housing formed with a loading slot having the optical disc pass therethrough; a turntable for retaining the optical disc and, the turntable being supported by the housing and having a center axis, the turntable being driven to rotate around the center axis with the optical disc and being retained by the turntable to reproduce information recorded in the optical disc while reading out information in the optical disc; a guide plate positioned within the housing in the vicinity of the loading slot and supported by the housing, the guide plate having an inner surface contactable with the optical disc to guide the optical disc toward the turntable until the optical disc is retained by the turntable after being partly passed through the loading slot; a rotation shaft having a center axis and supported by the housing with the center axis being in parallel relationship with the inner surface of the guide plate and with the inner surface of the guide plate extending toward the turntable, the rotation shaft having three different longitudinal portions including first and second side portions axially spaced apart from each other, and a spacer portion intervening between the first and second side portions, the first and second side portions being tapered toward the spacer portion; and driving means for driving the rotation shaft to have the rotation shaft rotate around the center axis to ensure that the optical disc is conveyed toward the turntable by the rotation shaft while the optical disc is being guided by the guide plate.

A switch-type oscillating circuit includes a first oscillating circuit for outputting an oscillation signal having a first frequency, which includes a first oscillation transistor and a first switch circuit for turning on and off the first oscillation transistor; a second oscillating circuit for outputting an oscillation signal having a second frequency, which includes a second oscillation transistor and a second switch circuit for turning on and off the second oscillation transistor; and a coupling circuit disposed between the output end of the first oscillating circuit and the output end of the second oscillating circuit, and the input end of a common circuit. A first low-pass filter circuit is connected between the output end of the first oscillating circuit and a common potential point, for attenuating the oscillation signal having the second frequency; and a second low-pass filter circuit is connected between the output end of the second oscillating circuit and the common potential point, for attenuating the oscillation signal having the first frequency.
Abstract:
An inkjet printing method including: discharging ink contained in an ink storage unit, from a nozzle of a nozzle forming surface of a discharging unit; and supplying the ink from the ink storage unit to the discharging unit. The ink includes specific components and satisfies a specific relation between dynamic surface tension and time. The supplying includes: forming a closed space by covering the nozzle forming surface with a lid member, and freely controlling a pressure between the discharging unit and the ink storage unit; and forming an open space by opening the lid member on the nozzle forming surface, and setting the pressure to be the same as atmospheric pressure. A negative pressure difference between the ink storage unit and the discharging unit is 70-120 mmAq before discharge of the ink, 30-80 mmAq during the discharging, and the former is equal to or greater than the latter.

Abstract:
An active-energy-ray-curable composition, a cured material of the active-energy-ray-curable composition satisfying a critical load of 5.0 g or more but 25.0 g or less, the critical load being obtained by a continuous loading test method using a variable normal load friction and wear measurement device, the cured material having an average thickness of 10 μm and being formed by coating the active-energy-ray-curable composition on a substrate and by irradiating and curing the active-energy-ray-curable composition with active energy rays having illuminance of 1.5 W/cm2 and an amount of irradiation of 200 mJ/cm2.
Abstract:
An active energy ray curable composition including a polymerizable compound is provided. When a three-layer cured product of the active energy ray composition is obtained by a specific procedure, the three-layer cured product has (1) a stretchability of 1.1 or more and (2) a glass transition temperature of 50° C. or more. The stretchability is defined by a ratio L2/L1, wherein L1 represents a first length of the cured product before a tensile test and L2 represents a second length of the cured product after the tensile test. The tensile test includes stretching the cured product along with the substrate with a tensile tester at a stretching speed of 20 mm/min and a temperature of 180° C.
Abstract:
A power control apparatus includes a processor that causes thermal fluid analysis of the amount of increase in power consumption for cooling a plurality of servers, where the increase in power consumption is consequent to an increase in the volume of tasks at each server among the servers. Based on analysis results obtained by the thermal fluid analysis, the processor selects from among the servers, a server to execute a task and causes the selected server to execute the task.
Abstract:
A method for producing a preform for manufacture of a fiber-reinforced plastic molding. The method includes: fixing a resin-equipped film rolled out from a roll state including a release film and a fixing resin and containing a partially-cured thermosetting resin, to a surface of the dry fiber fabric rolled out from a roll with the fixing resin interposed therebetween, thereby obtaining a first dry fiber fabric; separately fixing the resin-equipped film to a surface of the dry fiber fabric rolled out from a roll with the fixing resin interposed therebetween, and detaching the release film, thereby obtaining one or more second dry fiber fabrics; and laminating the second dry fiber fabrics on a surface of the first dry fiber fabric with the fixing resin of the second dry fiber fabrics interposed therebetween.
Abstract:
A synchronization timing detecting method for a receiving device which receives a radio signal including a known symbol on a certain cycle and a gap period which is formed with a certain timing relation based on a transmit timing of the known symbol, wherein synchronization is not achieved in the gap period and the gap period has a longer duration than a certain time, includes receiving the radio signal to detect the gap period in which symbol synchronization is not achieved and which is longer than the certain time, and detecting the known symbol at a timing determined by the certain timing relation based on the gap period detected.
