Abstract: A field effect transistor comprising: a non-doped diamond layer which has a hydrogen-terminated surface; first and second p+diamond layers which are formed on the non-doped diamond layer and sandwich a hydrogen-terminated region; a source electrode which is formed on the first p+diamond layer and is made of metal; a drain electrode which is formed on the second p+diamond layer and is made of metal; an insulating layer which is formed on the hydrogen-terminated region of the non-doped diamond layer; and a gate electrode which is formed on the insulating layer, a mutual conductance being equal to or higher than 0.5 mS/mm at room temperatures, after an X-ray is applied for an amount of 5 Mgy.

Abstract: This vehicle cooling device includes a duct communicating with a heating element disposed in a vehicle, an opening provided in the duct, positioned below a seat surface part of a seat disposed above a floor panel, and opening to a passenger compartment, and a fan supplying air suctioned into the duct from the opening to the heating element, in which the opening is positioned on a vehicle-body rear side with respect to a seat fixing part on a vehicle-body front side among seat fixing parts for fixing the seat to the floor panel in a state in which it is disposed on a vehicle-body rear side of a front end of the seat surface part.

Abstract: A battery protection apparatus fixed to a vehicle body and provided on a side surface of a battery pack, includes a first portion configured to be inclined toward the battery pack side from a lower side to an upper side; an extension portion configured to extend from a lower end of the first portion in a direction being apart from the battery pack; and a second portion provided between the first portion and the battery pack, wherein the first portion and the second portion forms a hollow portion.

Abstract: A vehicle control device has a plurality of speakers and a security ECU which identifies whether a door is opened or unlocked on the basis of output signals from the speakers. The security ECU identifies the driving direction of a driven portion on the basis of the difference between input times of sounds inputted to the speakers. Moreover, the ECU has RAM containing the waveforms of the signals outputted from the speakers and compares the waveforms of the signals contained in the RAM with the waveforms of the signals outputted from the speakers to identify the driving direction of the driven portion.

Abstract: An anti-theft system of a vehicle includes multiple speakers 1, 2, 3 and 4 that detect an impact applied to the vehicle; and a security ECU 10 that executes a detection unit identification process for identifying a speaker that detects the impact first on the basis of values of signals from multiple speakers 1, 2; 3 and 4; an impact location estimation process for estimating that the impact is applied to a window glass when a value of a signal from the identified speaker is greater than or equal to a predetermined threshold value, and estimating that the impact is applied to a vehicle body when the value of the signal from the identified speaker is less than or equal to the predetermined threshold value; and an impact location identification process for estimating a distance between the estimated detection unit and a generation source of the impact by a correction coefficient for a case that the estimated impact location is the window glass when the estimated impact location is the window glass, estimating th

Abstract: Multiple speakers mounted to a vehicle, and a body ECU which includes a unit that identifies a driven part of the vehicle which is knocked based on input information from the multiple speakers, and a unit that drives the identified driven part. The body ECU identifies the driven part on the basis of the difference between input times of a sound input to the multiple speakers. The body ECU determines whether the user carries a portable device, and determines whether to permit or not the drive of the driven part.

Abstract: The invention relates to a process for producing a trifluoromethylbenzylamine represented by the following general formula (1). This process includes hydrogenating a trifliuoromethylbenzonitrile represented by the following general formula (2) by hydrogen in an organic solvent in the presence of ammonia, using a Raney catalyst, where each R independently represents a halogen selected from the group consisting of fluorine, chlorine, bromine and iodine, an alkyl group having a carbon atom number of 1-4, an alkoxy group having a carbon atom number of 1-4, an amino group, a hydroxyl group or a trifluoromethyl group, and n represents an integer from 0 to 4, where R and n are defined as above. With this process, it is possible to obtain the trifluoromethylbenzylamine easily and inexpensively at an extremely high yield.
