Abstract: A waveguide, that is improved in size, costs, manufacturing and in durability, has a base having a mounting surface, and a plate member held on the mounting surface of the base for defining a waveguide in cooperation with the base. The mounting surface of the base is a curved surface defined by a sweep of a flexure curve of the plate member when it is loaded along a straight line. The plate member is attached to the base in such a manner that the plate member is pressed against and curved along the mounting surface, and that the plate member has a curvature direction edge portion extending in a curvature direction which is a general extension of the flexure curve and a sweep direction edge portion extending in a direction of the sweep of the curve.

Abstract: The cooling system includes a heat exchanger, the circulating pump, a first refrigerant channel in which an electric device and the circulating pump are provided, a second refrigerant channel connected to the first refrigerant channel so as to form a circulation channel of the refrigerant, in which the heat exchanger is provided, a bypass channel connected to the first refrigerant channel in parallel to the second refrigerant channel, in which a charger is provided, and a valve provided at a position where the first refrigerant channel and the bypass channel are connected to each other, for forming a circulation channel of the refrigerant, the circulation channel including the first refrigerant channel and the second refrigerant channel, to restrict a flow of the refrigerant through the bypass channel when the electric device is in operation.

Abstract: A passenger protection apparatus of a simple construction is capable of stably performing air bag control and preventing erroneous control due to objects such as passenger's hands, newspapers, etc., other than passenger' head. A collision detection part detects a collision of a vehicle, and an object detection part detects an object in a prescribed object detection area rearwardly of an air bag installation surface in the vehicle based on a signal from a sensor. An air bag control signal generation part controls the expansion of an air bag based on the detection results of the object detection part and the collision detection part. The air bag control signal generation part makes the air bag control signal into an expansion permission signal only when an object exists in the object detection area at the time of detection of the collision or within a predetermined time from the detection of the collision.

Abstract: A sensor in a car window permits a reduction in size thereof. The sensor includes a lens that is provided on the inner side of a sloping windshield to condense light coming from an object to be detected that is located outside the windshield, a sensor main body that detects the object to be detected by means of the light that has passed through the lens, and a transparent glass pane that is provided between the windshield and the lens to refract the light from the object to be detected that has passed through the windshield.

Abstract: A sensor in a car window prevents dew from being formed only on a lens in a hood thereof and the car window even when temperature changes, and also protects the lens and the car window from contamination by floating particulates, such as cigarette smokes. The sensor in a car window is formed of a camera that has a hood partitioned in consort with the car window from a vehicle compartment area, and a camera main body that includes a lens projecting within the hood and detects, through the lens, an object located in front thereof. A breathable dustproof filter is provided on a part of the hood.

Abstract: A camera provided with entrance windows, through each of which extraneous light are taken in, in both side portions of a housing, respectively. Further, an image pickup device is mounted in the housing. Moreover, an optical element is placed in a stage prior to the aforesaid image pickup device. This optical element reflects the extraneous light once, which is incident from a one of the aforesaid entrance windows, and forms an inverted mirror image on an area of an imaging plane of the aforesaid image pickup device, which corresponds to the one of the aforesaid entrance windows. Moreover, this optical element reflects the extraneous light once, which is incident from the other of the aforesaid entrance windows, and forms an inverted mirror image on an area of said imaging plane of said image pickup device, which corresponds to the other of the aforesaid entrance windows. Thus, in accordance with this camera, the reflection of the extraneous light is performed once.
