摘要:
Signals subjected to orthogonal modulation with a plurality of carrier frequencies are added to detect peak power. Based on the peak power, a coefficient for suppressing an amplitude of a transmission baseband signal is calculated. Using the coefficient, the amplitude of a baseband signal to be inputted to a filter is suppressed. It is thereby possible to suppress the peak power assuredly, and by the effects of the filter, unnecessary frequencies are not generated.

A small number of users who provide high interference in the other users, such as a user transmitting a high rate signal, are selected beforehand. First, a signal of the user is demodulated to generate a replica, and a difference between a received signal and the replica is calculated, thereby canceling the interference in signals of the other users, and further improving the system capacity.

Provided is an X-ray imaging apparatus and an X-ray imaging method that offer an alternative for a refraction contrast method.A first scintillator and a second scintillator are used, the first scintillator generating first fluorescent light when X-rays separated by the separating element are incident thereon, and a second scintillator generating second fluorescent light when X-rays separated by the separating element are incident thereon. The second scintillator has a fluorescence emission intensity gradient such that an amount of emitted fluorescent light changes in accordance with a change in a position at which the X-rays are incident.

An eco drive support apparatus which reports the eco degree of the driving operation of a vehicle by displaying a state relative to a judgment threshold which varies corresponding to the drive state of the vehicle. The apparatus has a power train ECU which computes the judgment threshold and an eco drive state amount expressing a ratio to the judgment threshold on the basis of the drive state of the vehicle and a meter ECU which indicates the eco drive state amount on the basis of information transmitted from the power train ECU. The power train ECU transmits the eco drive state amount to the meter ECU.

An X-ray detector includes an X-ray photoelectric conversion layer configured to produce electric charges in proportion to X-ray irradiation incident on the layer, a collecting electrode configured to collect the electric charges produced by the X-ray photoelectric conversion layer, a common electrode disposed on a surface of the X-ray photoelectric conversion layer opposite to the collecting electrode, a storage capacitor configured to store the electric charges collected by the collecting electrode, and a readout unit configured to read out the electric charges stored in the storage capacitor. A voltage is to be applied between the collecting electrode and the common electrode. The X-ray photoelectric conversion layer is formed of a polycrystalline oxide.

An eco-drive assist apparatus displays a quantity of eco-drive that indicates a degree of ecology and/or economy in driving in a hybrid vehicle equipped with an engine and a motor. The apparatus includes a first part configured to calculate the quantity of eco-drive on the basis of a vehicle power generated in the vehicle, and a second part configured to cause the quantity of eco-drive to be displayed in a graphic manner as a relative quantity to an eco-drive judgment threshold value that indicates whether the vehicle is in an eco-drive state and as a relative quantity to an engine startup threshold value that indicates whether the engine has been started up and configured to cause the quantity of eco-drive to be displayed on a boundary of the engine startup threshold value or displayed at a position where the quantity of eco-drive is worse than the engine startup threshold value when the engine has been started up. The second part causes the quantity of eco-drive to be displayed at a position where the quantity of eco-drive is better than the engine startup threshold value when the engine has been started up and a driver's operation needs no vehicle power.

A pigment ink composition has high transparency and good color characteristics such as a high OD that are not inferior to those of dyes, even though pigment particles are used, and also has good weatherability and remaining ability on the coating and printing medium surface that are inherent to pigment particles. The pigment ink composition contains pigment particles including at least needle pigment particles, a dispersant, and a solvent. The needle pigment particles have a needle shape with an aspect ratio of at least 3, an average aspect ratio of at least 5 and at most 7, an average short dimension of at least 20 nm and at most 30 nm, and a distribution of short dimension with a standard deviation of 2.0 nm or less. The needle pigment particles are covered with the dispersant.

A simplified X-ray imaging apparatus is capable of computationally determining effective atomic numbers with small error factors even for light elements. The X-ray imaging apparatus has an X-ray generation unit 101 (400) for generating X-rays and a detector 105 (405) for detecting X-rays transmitted through an object of examination 104 (403). A computing unit 106 (406) computationally determines a quantity of an X-ray phase attributable to the object of examination and an X-ray transmittance of the object of examination from data detected by the detector. The computing unit also computationally determines an effective atomic number of the object of examination from ρet determined from the quantity of the X-ray phase and μt it determined from the X-ray transmittance.
