20160023681 | FRONT VEHICLE BODY STRUCTURE - A front vehicle body structure has a member provided at a side section of a vehicle body along a vehicle-body front-rear direction, a powertrain disposed on an inner side of the vehicle body relative to the member and fixed to a front section of the vehicle body, and a load transmission member provided on the member and configured to come into contact with one end portion, in a vehicle width direction, of the powertrain when receiving a collision load applied by an obstacle from a front side of the vehicle body, and to transmit the load from the obstacle to the powertrain in a state of being sandwiched between the obstacle and the powertrain. The load transmission member has a concave curved surface formed in a surface thereof along the vehicle-body front-rear direction. The concave curved surface is elastically deformed in the state of being sandwiched between the obstacle and the powertrain and receiving the load. | 01-28-2016 |

20100194468 | SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE, COMMUNICATION DEVICE, INFORMATION REPRODUCING DEVICE, IMAGE DISPLAY DEVICE, ELECTRONIC DEVICE, ELECTRONIC CONTROL DEVICE, AND MOBILE BODY - In order to suppress an instantaneous carrying current (surge current) and power supply noise caused by the instantaneous carrying current (the surge current), the power supply cutoff structure of a semiconductor integrated circuit device comprises a switching circuit for controlling a power supply to a controlled circuit. The switching circuit includes a plurality of transistors each having a different current capability. The transistors are sequentially provided with a certain regularity, including from a low current capability transistor up to a high current capability transistor. | 08-05-2010 |
