Abstract:
Predetermined travel locuss are set in a three-dimensional virtual space. Menu panels displaying menu items are arranged along the travel locuss assuming a display position set as a local origin so that the normal to each LCD panel will face a virtual camera. The transparency of a menu panel is raised in accordance with its distance to the virtual camera. A scroll operation moves menu panels along the travel locuss connecting display positions P until a selected specific menu panel reaches the display position P0. A display screen is drawn with the virtual camera and menu panels are three-dimensionally displayed in rolls.By sliding a stylus pen on the LCD panel, the menu screen displayed on the LCD panel scrolls at a velocity corresponding to the drag velocity. When the stylus pen is released from the LCD panel, an application program corresponding to the menu display entity (crosshatched) is activated.
Abstract:
A heat radiating component includes a base including a first metal, a first plating layer formed on the base and including a second metal and carbon material structures dispersed in the second metal, and a second plating layer formed on the first plating layer. The first plating layer includes protruding parts that are parts of the carbon material structures protruding from a surface of the second metal. The second plating layer is formed on the first plating layer to cover surfaces of the protruding parts and the surface of the second metal without filling spaces between the protruding parts.
Abstract:
A solder bump forming method of carrying out a reflow treatment over a conductive ball mounted on a plurality of pads, thereby forming a solder bump, includes a metal film forming step of forming a metal film capable of chemically reacting to a tackifying compound on the pads, an organic sticking layer forming step of causing a solution containing the tackifying compound to chemically react to the metal film, thereby forming an organic sticking layer on the metal film, and a conductive ball mounting step of supplying the conductive ball on the pads having the organic sticking layer formed thereon, thereby mounting the conductive ball on the pads through the metal film.
Abstract:
In a reaction chamber (20), a used alkaline permanganate etching solution (12) is accommodated and an alkaline earth hydroxide (14) such as calcium hydroxide is added in the reaction chamber, a liquid inside of the reaction chamber is agitated, the liquid is exhausted from a side portion or a top portion of the reaction chamber through a filter (28), a precipitate (26) adhered to the filter is scraped off, and a precipitate containing a hardly soluble or insoluble matter incapable of passing through the filter and accumulated on a bottom portion of the reaction chamber is exhausted from the reaction chamber.
Abstract:
The present invention provides a non-cyanide electroless gold plating solution free from a cyanide compound, comprising, as a completing agent of gold, a compound represented by the formula shown below or a salt thereof: X—(CH2)n—SH wherein n is 2 or 3 and X is SO3H or NH2, and having a pH value of 7 or less. The invention also provides a process for electroless gold plating using the non-cyanide electroless gold plating solution.
Abstract:
In an antilock brake device, a determining function of which the sign varies when a wheel slip ratio is identical to a target value, and a switching function comprising an integral term which is a time integral of the determining function, are set, and a brake torque target value is determined so that it is proportional to the switching function. Alternatively, the brake torque target value computed according to the determining function is corrected according to a wheel angular acceleration. In this way, a brake torque or the wheel slip ratio between a road surface and tires is precisely controlled.
Abstract:
A method for manufacturing a lead frame employing a resist pattern formed on a matrix and having a cavity therein, in which an electro-deposition pattern is formed. A connecting cavity portion interconnects tip ends of inner lead cavity portions such that a connecting portion interconnects the tip ends of inner leads of the electro-deposition pattern formed in the cavity. The connecting piece is maintained while the electro-deposition pattern is separated from the matrix and the resist.
