Title: Electronic component
Inventor: TATEISHI YUJI
IPC: H01G4/30
Filed: 2013-10-31
Abstract: PROBLEM TO BE SOLVED: To provide an electronic component capable of easily finding a defect, such as a crack, therein.SOLUTION: An electronic component comprises a main unit mainly constituted of a colored ceramic material. Since surfaces 3 of the main unit 1 of the electronic component are glossy surfaces, scattering of light on the surfaces 3 of the main unit 1 can be suppressed, and permeability of the light into the main unit 1 is increased. Thus, a state of the inside of the main unit 1 can be easily confirmed even when the color of the main unit 1 is not white. For example, when a defect 5, such as a crack, is generated inside the main unit 1, a shape of the defect 5 appears as an image shown by the transmitting light since reflectance of a basis material of the main unit 1 and that of the defect 5 are different. Thus, the defect 5 can be confirmed from the outside visually or by microscopy.

Title: Drive force distribution control device for four-wheel drive vehicle
Inventor: OYAGI SHOICHI
IPC: B60K17/348
Filed: 2013-11-05
Abstract: PROBLEM TO BE SOLVED: To properly control drive force power distribution according to a theoretical normative model while to cope with variation that cannot be compensated by the normative model.SOLUTION: Based on steering angle, car speed, yaw rate and slip angle of a four-wheel drive vehicle, a theoretical rotational speed value of a main drive wheel and a theoretical rotational speed value of a sub drive wheel are respectively obtained. From the values, a rotational difference (ΔN) normative theoretical value that is a difference between input/output shaft theoretical rotational speed values of a drive force distribution device is obtained (theoretical value calculation part 71). Based on ΔN measurement value representing actual input/output shaft rotation difference of the drive force distribution device and ΔN normative theoretical value, ΔN normative value obtained by correcting the ΔN normative theoretical value is obtained (normative calculation part 72). By servo control the ΔN measurement value whose target value is the ΔN normative value, a driving force to the sub drive wheel which is distributed by the drive force distribution device (10) is corrected (servo control part 73). A filter process is performed so that the ΔN normative value does not change in response to temporary change in deviation between the ΔN measurement value and the ΔN normative theoretical value.
