Abstract: A gun-type controller includes a main grip and a subgrip respectively provided to the rear portion and the front portion of a barrel. The view point direction of a view point camera CM is input using a main lever provided at a position reached by the thumb when holding the main grip with the right hand, and the moving direction of a player's character PC is input using a sublever provided at a position reached by the thumb when holding the subgrip with the left hand.

Abstract: A gun-type controller has an outward appearance imitating an automatic rifle in which a main grip and a subgrip extend from a barrel, and is used in a state in which the player holds the gun-type controller in the forward/backward direction and aims a muzzle at a screen. A view point direction lever for inputting the view point direction of a player's character is provided at a position at which the thumb reaches the view point direction lever when the player holds the main grip with the right hand, and a moving direction lever for inputting the moving direction of the player's character is provided at a position at which the thumb reaches the moving direction lever when the player holds the main grip with the left hand.

Abstract: A fire retardant multilayered printed wiring board without halogen compounds, having enhanced thermal conductivity of insulator layers to prevent electronic components from being damaged during soldering. The insulator layers are formed of a glass cloth impregnated with an epoxy resin composition. Metal foil layers, in each of which a circuit is formed, are laminated alternately with the insulator layers. The epoxy resin composition includes at least phosphate ester, aluminum hydroxide, silica, calcium oxide, strontium titanate, and iron oxide. Inorganic components are provided in the insulator layers as about 8% to about 18% by mass of P2O5, about 20% to about 28% by mass of Al2O3, about 0.1% to about 0.6% by mass of SiO2, about 0.1% to about 1.0% by mass of Cl, about 15% to about 20% by mass of CaO, about 0.3% to about 0.5% by mass of TiO2, about 0.2% to about 0.4% by mass of Fe2O3, and about 0.1% to about 0.3% by mass of SrO, in converted values as measured by an X-ray fluorescence analysis.

Abstract: A Ceramic Bonding Copper (CBC) substrate used in semiconductor modules includes a ceramic plate having foil-shaped copper plates bonded to the ceramic plate by the direct copper bonding method. A circuit pattern is formed on one of the copper plates. The ceramic plate is fabricated by sintering at high temperature an alumina powder compact containing zirconia and one or more of the following additives: yttria, calcia, magnesia, and ceria. The flexural strength and the thermal conductivity of the alumnina ceramic plate of the invention are remarkably improved, facilitating a reduction in the thickness of the ceramic plate. The reduction in thickness of the CBC substrate further improves the ability of the semiconductor device to radiate heat and therefore increases the current carrying capability of the semiconductor device.

Abstract: A ceramic substrate is a high-temperature fired body consisting of alumina as the main component, zirconia, and a ceramics sintering assisting agent. The assisting agent is one of yttria, calcia, magnesia, and ceria, in which yttria is added at 0.1-2 wt %, calcia is added at 0.02-0.5 wt %, magnesia is added at 0.02-0.4 wt %, and ceria is added at 0.02-0.5 wt %.

Abstract: A disk storage device includes a fixed information storage disk that is free from deformation, has a wide effective data storage area and shows excellent anti-mechanical shock properties. Specifically, a disk hole of the information storage disk is fit to a hub coupled to a rotary shaft of a spindle motor until the disk contacts with a flange face of the hub. The spindle motor and the disk are then sandwiched by a lower electrode which contacts with the bottom surface of the spindle motor and an upper electrode which contacts with the upper surface of the disk. A DC power supply applies positive potential to the hub via the lower electrode and the casing of the spindle motor and negative potential to the disk via the upper electrode. An electrostatic junction portion is formed between the bottom face of the disk and the flange face of the hub, thereby securing the disk tightly to the hub.

Abstract: The method of bonding silver-based contact is disclosed. A silver-based contact is brought into contact with a support, at least the surface of which is made of a cupreous material, with a pressure of less than 1 kgf/cm.sup.2 exerted therebetween. The contact and support are heated in a non-oxidizing atmosphere at a temperature of more than 700.degree. C.

Abstract: A contact member for a switching device is formed by soldering a contact tip to a movable contact member. The movable member is formed from an age-hardenable copper alloy that has been subjected in series to solution treatment, half age-hardening, grinding and rust-prevention coating.

Abstract: A method of manufacturing stationary electromagnetic cores utilizes mild steel having a carbon content of up to 0.01% by weight and an impurity content of less than 0.31% by weight. Use of this material lowers the cost of manufacturing electromagnetic cores by shortening the drawing process and obviating the necessity for magnetic annealing.
