Abstract: An alkaline dry cell includes a cathode, an anode, a separator disposed between the cathode and anode, and an electrolyte held within the cathode, anode, and separator. The cathode includes manganese dioxide. A width at half maximum W of a (110)-plane diffraction peak in an X-ray diffraction pattern of the manganese dioxide is 2.4° or less. The anode includes powder of an anode active material including zinc. Particles s of the powder with particle diameters 75 ?m or less account for 33% by mass or more of all particles of the powder. A thickness of the separator is 150 ?m or more and is 210 ?m or less.

Abstract: An alkaline dry battery includes a positive electrode, a negative electrode, and a separator disposed between the positive electrode and the negative electrode. The positive electrode contains electrolyte and the negative electrode contains electrolyte. The positive electrode further contains electrolytic manganese dioxide, sodium, and zinc. The electrical potential of the electrolytic manganese dioxide is 300 mV or higher and 340 mV or lower with respect to that of a reference electrode made of mercury oxide. The content of the sodium in the positive electrode is 800 ppm by mass or more and 3000 ppm by mass or less. The content of the zinc in the positive electrode is 2400 ppm by mass or more and 4600 ppm by mass or less.

Abstract: A method for manufacturing an alkaline dry battery includes first to third steps. In the first step, a hollow cylindrical first positive electrode pellet including a first end face and a second end face is prepared in an axial direction is prepared. In the second step, a hollow cylindrical positive electrode pellet group including the first positive electrode pellet is inserted into a case to obtain a positive electrode inscribed in the case. At this time, the first positive electrode pellet is disposed on the most opening side of the case such that the first end face faces an opening side of the case. In the third step, an annular groove is provided in a side part of the case.

Abstract: A lighting apparatus for a vehicle includes headlamps configured to be switchable between high beam and low beam, wherein a direction of an optical axis of each of the headlamps is variable in a substantially horizontal plane by use of a swivel actuator and a controller configured to control the headlamps, wherein if the controller detects a forward vehicle in projection areas of the headlamps, the controller temporarily switches from the high beam to the low beam, then drives the swivel actuator toward a target swivel angle according to a position of the detected forward vehicle and, after finishing driving toward the target swivel angle or during driving toward the target swivel angle, starts projection by the high beam.

Abstract: A vehicular light distribution control system (100) controls a light distribution of headlights (3). The control system includes the following parts. The vehicle detecting part (10) detects an anterior vehicle driving in front of an occupants vehicle. The unirradiated region setting part (12) sets a region where the anterior vehicle detected by the vehicle detecting part (10) exists as an unirradiated region. The vehicle motion estimating part (13) estimates an ensuing motion of the anterior vehicle detected by the vehicle detecting part (10). The unirradiated region adjusting part (14) adjusts a size of the unirradiated region set by the unirradiated region setting part (12) depending on an estimated result 15 of the vehicle motion estimating part (13).

Abstract: A light distribution control system for a vehicle that is configured to control a light distribution of a head lamp, the system comprising: a vehicle detecting part configured to detect a forward vehicle that travels ahead of a host vehicle; and a light distribution controlling part configured to set a non-illumination region for a region in which the forward vehicle detected by the vehicle detecting part exists, wherein the light distribution controlling part changes, between a case in which the forward vehicle detected by the vehicle detecting part is a preceding vehicle and a case in which the forward vehicle detected by the vehicle detecting part is an oncoming vehicle, at least one of a margin amount of the non-illumination region in a width direction, a movement speed of the non-illumination region, and a variable range of the non-illumination region.
