A semiconductor pellet and chip components are provided on an insulating substrate, and are sealed with a molding resin that is molded by transfer molding. The chip components are positioned so as to surround the semiconductor pellet on all four sides. The lengthwise directions of the chip components surrounding the semiconductor pellet are aligned in a uniform direction. The insulating substrate is set within a die molding apparatus so that during resin injection, the lengthwise directions of the chip components are aligned substantially perpendicularly to the direction of flow of the injected resin.

摘要:
A carrier reproducing apparatus and method enabling stable operation even at a low S/N, wherein, when phase signals are locked and exceed a predetermined value, a tracking circuit generates a signal and an oscillation frequency of a signal output from a numerical control oscillation circuit is controlled so that the phase signals do not exceed the predetermined value and wherein a down sampling circuit and an interpolation circuit convert signals having a frequency of more than twice the symbol rate to signals having a frequency of twice the symbol rate.
摘要:
The present invention relates to a drive device for one or more series-connected cold cathode fluorescent lamps having an electrical terminal at each end. The drive device has a piezoelectric transformer for converting by means of the piezoelectric effect a primary ac input applied to primary electrodes to a secondary ac output, which is removed from secondary electrodes; a drive arrangement for applying the primary ac input to the primary electrodes; and a brightness control circuit for controlling brightness. The drive device is configured so that the end electrical terminals of the cold cathode fluorescent lamp can be connected between the two secondary electrodes. The brightness control circuit detects the phase difference between the secondary ac output and the primary ac input. When the detected phase difference is greater than a specified phase difference, the drive arrangement reduces the power of the primary ac input applied to the primary electrodes. If the detected phase difference is less than the specified phase difference, the drive arrangement increases the power of the primary ac input applied to the primary electrodes.

In an inkjet head acting as a liquid ejecting head for carrying out a print operation by ejecting liquids onto a medium to be recorded, the inkjet head including two rows of orifice arrays, which are disposed approximately parallel with each other and a group of supply ports for feeding the liquids to the orifice arrays, the orifice arrays and the supply ports being arranged integrally, and only one of the two rows of the orifice arrays being used, a dummy heater board having the same shape as that of a heater board is caused to come into intimate contact with an unused side liquid chamber. Further, ribs are disposed in the vicinity of an unused side ink path so as to increase strength. With this arrangements, an intimate contact property can improved, irregular print can be eliminated and the disposition of orifice arrays on a top plate as a single isolated member can be reproduced even at the time the inkjet head is completed.

Hydrochloride of fumarate of 1-{2-[(2R)-(3,4-dichlorophenyl)-4-(3,4,5-trimethyoxybenzoyl)morpholin-2-yl]ethyl}spiro[benzo(c)thiophene-1(3H),4′-piperidin]-(2S)-oxide. These compounds have good oral adsorption and exhibit markedly excellent antagonistic action against both NK1 receptors and NK2 receptors. These compounds are useful as an active ingredient in pharmaceutical compositions for administering to patients for treatment of tachykinin-medicated diseases.
