Abstract:
A vehicle is able to contactlessly receive electric power from a power transmitting device and to charge a mounted electrical storage device (electric load). The vehicle includes a communication unit that carries out wireless communication with the power transmitting device and a vehicle ECU (control fit) that controls the communication unit. The communication unit is able to switch a communication range between a wide communication range (wire-area communication) and a narrow communication range (narrow-area communication). The vehicle ECU, at the time of identifying a power transmitting device from which electric power should be received, controls the communication unit such that the communication unit communicates with the power transmitting device using the narrow-area communication.
Abstract:
A contactless power transfer system supplies power from a power transmitting device to a vehicle in a contactless manner. The power transmitting device and the vehicle are configured to be capable of exchanging information with each other through radio communication. The vehicle is provided with an RFID tag in which infoiivation on the vehicle is stored in advance. The power transmitting device includes an RFID reader that reads out information from the ID tag in a contactless manner. A power transmitting ECU recognizes that the vehicle is a vehicle to be supplied with power from the power transmitting device if vehicle information indicated by information from the ID tag corresponds to vehicle information indicated by information received through radio communication.
Abstract:
The present invention relates to a photomultiplier having a structure for making it possible to easily realize high detection accuracy and fine processing, and a method of manufacturing the same. The photomultiplier comprises an enclosure having an inside kept in a vacuum state, whereas a photocathode emitting electrons in response to incident light, an electron multiplier section multiplying in a cascading manner the electron emitted from the photocathode, and an anode for taking out a secondary electron generated in the electron multiplier section are arranged in the enclosure. A part of the enclosure is constructed by a glass substrate having a flat part, whereas each of the electron multiplier section and anode is two-dimensionally arranged on the flat part in the glass substrate.
Abstract:
Provided is a case hardening steel which allows effective inhibition of abnormal grain growth during carburizing treatment or the like and makes it possible to solve the problem of abnormal grain growth-induced reduction in characteristics. In the case hardening steel, a total amount of TiC, ZrC and AlN which are precipitate particles contained in 100 g of a steel material after subjecting the case hardening steel to hot rolling is 3.5×10−4 mole or less.
Abstract:
Electric charge remaining on a photoreceptor after transfer causes image deterioration. According to one conventional method widely used in view of this problem, erase light is emitted onto a photoreceptor after the transfer to remove the electric charge remaining on the photoreceptor. However, such a method poses the following problem: emission of erase light leads to light-induced fatigue of the photoreceptor, and as a result, the photoreceptor which has deteriorated from the light-induced fatigue wears down due to abrasion and the like with a cleaner blade, resulting in a shorter lifetime of the photoreceptor. Thus, the thickness of the photosensitive layer is detected to acquire the amount of thickness decrease, and the amount of the erase light is reduced according to the acquired amount of thickness decrease.
