Abstract: A driving support ECU (21) of a driving support device (11a) executes automatic deceleration control for decelerating a vehicle (10) without a driver operating a brake pedal (105) when it is determined that a specific condition indicating that the driver intends to turn the vehicle (10) to the right or left at an intersection present in front of the vehicle (10) is satisfied. When a direction indicator (34, 35) stops operating during execution of the automatic deceleration control, the driving support ECU (21) continues the automatic deceleration control until a predetermined time period elapses from a time point at which the direction indicator (34, 35) stops operating, and ends the automatic deceleration control when the direction indicator (34, 35) continues to stop operating from when the direction indicator (34, 35) stops operating until the predetermined time period elapses.

Abstract: A driver assistance device includes a processor. The processor is configured to perform deceleration assistance control when a driver of a vehicle is not depressing an accelerator pedal, the deceleration assistance control being control for automatically decelerating the vehicle. The processor is configured to detect an operation of the accelerator pedal. The processor is configured to cancel the deceleration assistance control when the operation of the accelerator pedal is detected during the deceleration assistance control. The processor is configured to reduce a deceleration control amount for the deceleration assistance control according to a degree of the operation of the accelerator pedal, when cancelling the deceleration assistance control.

Abstract: A speaker includes a magnetic circuit, frame, diaphragm, voice coil, and terminals. The frame has an opening and is coupled to the magnetic circuit, and includes a resin portion. The diaphragm is coupled to a rim of the opening of the frame. The voice coil includes lead wires and is coupled to the diaphragm, and a part of the voice coil is disposed at a magnetic gap of the magnetic circuit. The terminals are coupled to the frame by insert-molding. An outer shape formed of the frame and the terminals is one of a rectangle or a square. The resin portion of the frame has cut-away sections at corners of its outer shape. The terminals include protruding sections protruding from the cut-away sections, and the lead wires of the voice coil are connected to the protruding sections.

Abstract: A freestanding GaN single crystal substrate is made by the steps of preparing a (111) GaAs single crystal substrate, forming a mask having periodically arranged windows on the (111) GaAs substrate, making thin GaN buffer layers on the GaAs substrate in the windows of the mask, growing a GaN epitaxial layer on the buffer layers and the mask by an HVPE or an MOC, eliminating the GaAs substrate and the mask away and obtaining a freestanding GaN single crystal substrate. The GaN single crystal has a diameter larger than 20 mm and a thickness more than 0.07 mm, being freestanding and substantially distortion-free.

Abstract: The present invention relates to a method of hot rolling copper or copper alloys such as copper wires and coppr plates. The present invention has succeeded in remarkably prolonging useful life of the tools used for hot rolling, and improving the surface quality of the rolled products by replacing the conventional methods of hot rolling copper using tools made of cemented carbide, die steel, high-speed steel, etc. by a method using tolls made essentially of Si.sub.3 N.sub.4. Si.sub.3 N.sub.4 tools used in the present invention contain at least one kind of sintering aid selected from the group consisting of Al.sub.2 O.sub.3, AlN, MgO, Y.sub.2 O.sub.3 and ZrO.sub.2, have a sintering density of 90% or more, Rockwell hardness of 88 or more and an average particle diameter of 2.mu. or less, and contain .beta.-type Si.sub.3 N.sub.4 as a main ingredient.

Abstract: A novel method of hot rolling iron and iron alloy rods, using a hot rolling tool comprising .beta.-Si.sub.3 N.sub.4 and a sintering aid selected from the group consisting of Al.sub.2 O.sub.3, AlN, MgO, Y.sub.2 O.sub.3 and ZrO.sub.2, and having a sintered density of 90% or more, Rockwell hardness of 88 or more and a mean particle size of 2.mu. or less.

Abstract: The invention relates to an aqueous electrolytic cathode and/or anode in which an aqueous solution of alkaline metal hydroxide is used or an active nickel or nickel alloy electrode having greater stability and smaller overvoltage under the condition of high current density for use in electrolysis of aqueous solution of alkaline metal halide, and the method for producing the same. Electrode material consisting of nickel or nickel alloy or electrode material of multiple layers comprising said electrode material coated with nickel or nickel alloy powder is forcibly subjected to oxidization and reduction treatments in repetition under a selected treatment temperature and atmosphere so that the surface area is expanded by the production of surface openings, thereby enabling to obtain an electrode having the said high properties.
