A vehicular lamp fitting and the like capable of preventing (or suppressing) vibrations of a radar unit (and as a result, capable of preventing the detection area of the radar unit from being significantly changed) are provided. A vehicular lamp fitting includes: a lamp housing; an outer lens attached to the lamp housing, the outer lens including a recessed part and forming a first space between the outer lens and the lamp housing; a lamp unit disposed in the first space; a radar cover disposed while covering the recessed part, and forming a second space between the radar cover and the recessed part; a bracket disposed in the second space; a radar unit detachably fixed to the bracket; and a first fixing part fixing one end of the bracket to the outer lens; and a second fixing part fixing the other end of the bracket to the lamp housing.

Vehicular lamp fitting and radar structure

A vehicular lamp fitting and the like capable of preventing the distance between a radar unit and the radar cover from changing are provided. A vehicular lamp fitting includes: a lamp housing; an outer lens attached to the lamp housing while covering an opening of the lamp housing, and forming a first space between the outer lens and the lamp housing; a lamp unit disposed in the first space; a radar housing; a radar cover attached to the radar housing while covering an opening of the radar housing, and forming a second space between the radar cover and the radar housing; a radar unit disposed in the second space; a first fixing part fixing the radar unit to the radar housing; and a second fixing part fixing the radar cover to the radar housing.

Vehicular lamp fitting, radar-cover removing method, and radar-cover attaching method

A lamp device has a base body to be installed to a vehicle; a lamp unit; a translucent cover that is installed to the base body, covering the front surface of the base body so as to accommodate the lamp unit therein, thereby defining a lamp body space, and has a recess in the front surface at a side position in a horizontal direction of the lamp unit; and a radar unit that has a radar sensor and a radar housing accommodating the radar sensor therein, and is inserted in the recess.

Lamp device

A notification device in a vehicle enables a person outside the vehicle to be notified of a predetermined operating state of the vehicle by the light emission, and includes: a plurality of spot-shaped light sources arranged at intervals to follow an upper edge of a windshield; a reflecting part reflecting light from the light sources to a front; an outer lens transmitting therethrough the light heading toward the front from the reflecting part; and a housing. The outer lens has on at least one of front and rear faces thereof a fine concave-convex face diffusing the light transmitted through the outer lens. Accordingly, the device is visible through an upper part of the windshield from a person outside the vehicle so that visibility is very good, and the light from the relatively small spot-shaped light source can be sufficiently diffused so that visibility can be further enhanced.

Notification device in vehicle

To raise the upper limit of the temperature range in which a quantum cascade laser (QCL) element for THz range operates at a single frequency. In a quantum cascade laser element in one embodiment of the present invention, each unit structureU in the active regionis provided with the first to fourth well layersW-Wthat are stacked in this order and separated from one another by at least one bather layerB. During application of a first bias electric field for lasing, the structure of electronic energy levels has a reception, upper lasing, lower lasing, and depopulation levels and emits electromagnetic waves at a first frequency. During application of a second bias electric field that is weaker than the first bias electric field, the overlap integral is 0.15 or less between electronic wavefunctions for the unnecessary upper lasing and unnecessary lower lasing levels, thereby stimulated emissions of electromagnetic waves are suppressed at frequencies other than the first frequency.

Quantum cascade laser element

According to an aspect of the invention, an image forming apparatus includes an image forming unit, a first detecting unit, a second detecting unit, a control unit. The image forming unit forms an image on a recording medium by using coloring materials of a plurality of colors based on image information. The first detecting unit detects whether or not the first given number of the first housing units are installed to the apparatus. The second detecting unit detects whether or not the second given number of the second housing unit and the third given number of the first housing unit are installed to the apparatus.

Image forming apparatus configured to use a cartridge including memory and a cartridge without memory

An image forming apparatus includes: a replaceable constituent element; an information storage unit that holds information indicating a type of the constituent element received by a user interface; and a life calculation controller that, when at least one piece of the information stored in the information storage unit indicates a particular type, performs control to suppress calculation of a life of the constituent element.

Image forming apparatus that determines when a life of a replacement unit has expired

An image forming apparatus that includes: an image forming apparatus main body; a replaceable unit which is attached to the image forming apparatus main body in a detachable manner; a storage unit provided in the replaceable unit, the storage unit storing information with respect to the replaceable unit; a first detecting unit that detects a first-stage operation for replacing the replaceable unit and other operation at a first stage of replacing the replaceable unit; a second detecting unit that detects a second-stage operation for replacing the replaceable unit at a second stage of replacing the replaceable unit; and a control unit that controls access to the storage unit in accordance with whether the second detecting unit detects the second-stage operation, when the first detecting unit detects the first-stage operation.

Image forming apparatus and method for controlling access to replaceable units

An image forming apparatus includes a developing device, a replaceable developing material container that contains developing material, a coupling member that couples the developing device to the developing material container, and a controller. The controller calculates a value obtained by calculating replacement time of the developing material container, on a developing material amount obtained by subtracting a developing material amount filled in the coupling member from a developing material amount contained in the attached developing material container, when the developing material container is attached and an installation sequence to fill the coupling member with developing material is performed. The image forming apparatus further includes a display that displays information indicating the replacement time of the developing material container based on the value calculated by the controller.
