Title: Semiconductor device
Inventor: OHNO YOUHEI
IPC: H01L21/02
Filed: 2015-05-22
Abstract: The present invention relates to a semiconductor device. In an HEMT having a structure of forming a via on an insulation film and taking a gate electrode out of a chip surface, it is difficult to raise a switching speed due to a problem of parasitic resistance caused by a layout of wiring and a problem of input capacitance. The via is formed on the insulation film directly above an area in which the gate electrode is opposed to a semiconductor through a gate oxide film, and the gate electrode is taken out of a chip surface therethrough. The gate electrode is taken out of the chip surface at the shortest distance, and thus it is possible to lower parasitic resistance as compared with a case of taking the gate electrode out at an end of the gate electrode. Accordingly, it is possible to shorten the switching time. It is preferable that the semiconductor device has a structure in which a relation of b>=a is satisfied and b/a represents a relation of 250>=b/a>=1, wherein a is the width of the via hole and b is the width of the area in which the gate electrode is opposed to the semiconductor through the gate oxide film.

Title: System and Method for charging toll fee with WAVE communication
Inventor: LEE KANG IK
IPC: G07B15/06
Filed: 2015-06-04
Abstract: According to the present invention, disclosed are a system and a method to charge a toll by using wireless access in vehicular environment (WAVE) communication. A WAVE communication unit sets a tolling zone specified by four pairs of coordinates within a WAVE communication zone and transmits beacon data about the tolling zone. When a vehicle enters the communication zone, a WAVE terminal inside the vehicle receives the beacon data to recognize the tolling zone, and determines whether the vehicle enters the tolling zone by comparing location information the vehicle with the tolling zone. When it is determined that the vehicle enters the tolling zone, the WAVE terminal transmits a response signal to the WAVE communication unit and the WAVE communication unit receiving the response signal performs a following process required to charge a toll to the vehicle. Since a tolling zone is set in a WAVE communication zone of a toll charging position, a toll is automatically charged when a vehicle including a WAVE terminal passes the tolling zone, so delay and congestion of the vehicle at the toll charging position can be dissolved. Moreover, it is not required to install a WAVE communication unit in each lane, so construction and maintenance expenses are reduced. Since a wide WAVE communication performance can be used as it is, other services can be provided.

Abstract: A laser beam from a light source part (4) is guided to an irradiated field (320) along an optical axis (J1) of an irradiation optical system (5). The irradiation optical system includes array of fly-eye lenses part (62) for dividing the light beams, and an optical path length difference generation part (61) having a plurality of transparent parts for inducing different path lengths on the sub-beams. Light fluxes having passed through the element lenses, respectively enter the transparent parts. A light condensing part (63) superimposes irradiation regions (50) of the light fluxes on the irradiation plane. When viewed in the arrangement direction of the element lenses, the light fluxes regarded as parallel light enter the light condensing part which includes a diverging lens (631) for causing the parallel light to diverge in a Y direction perpendicular to the arrangement direction, and a converging lens (633) for causing the light from the diverging lens to converge on the irradiation plane. This configuration readily achieves a design where the focal length of the light condensing part regarding the Y direction is reduced, and suppresses shifts in light condensing positions of the light fluxes on the irradiation plane.

IPC: H01S5/062
Filed: 2015-08-20
Abstract: The present invention relates to a method for adjusting a light emitting apparatus in which light with a short pulse width is emitted using a simple structure. A light source (101), a differentiation circuit (102), and a switch (103) are connected in series. When the switch (103) is turned on, inrush current flows through a condenser (102b) forming the differentiation circuit (102), so the light source is supplied with electric current and thereby emits light. When the condenser (102b) is charged, the electric current flows through a resistor (102a) and voltage drops at the resistor (102a). Accordingly, the voltage applied to the light source (101) is decreased, so the lighting is stopped. The method for adjusting a light emitting apparatus adjusts values of the resistor (102a) and the condenser (102b) so that the phenomenon occurs.
