An index picture as a still picture obtained by summarizing the contents of a moving picture, which is generated by using a video browser technique can be formed in various modes. A plurality of kinds of generating modes for generating an index picture by summarizing the contents of a moving picture are prepared, any of the modes is selected, and a generating process is performed in the selected mode. It enables an index picture to be generated in a proper form according to the property, use, and the like of a moving picture material.

A conductor pattern is formed on a resin film which is made of a thermoplastic resin. Each single-sided conductor pattern film has via-holes filled with an electrically conductive paste. A printed conductor pattern and a printed resistor are formed on a ceramic substrate. The single-sided conductor pattern films are laminated on the ceramic substrate. Then, the multilayered assembly is heated and pressed from both sides thereof to obtain a printed circuit board. During the heat and press treatment, respective single-sided conductor pattern films and the ceramic substrate bond together while the interlayer connection is obtained between the conductor patterns as well as between the conductor pattern and the printed conductor pattern.

An electronic component unit includes an interposer with a plurality of holes and a circuit wiring layer disposed on one surface of the interposer. The electronic component is electrically connected to the circuit wiring layer. A plurality of solder bumps are electrically connected to one surface of the circuit wiring layer through the holes formed in the interposer. The circuit wiring layer is electrically connected to an outside circuit through the solder bumps. A junction interface between the circuit wiring layer and each of the solder bumps is made of ductile metal.

When any of push-button switches on a handheld controller is pressed in a sound input mode, a video game machine generates and temporarily stores frequency data of a tone corresponding to the depressed switch. When a joystick on the controller is tilted to a predetermined direction, the video game machine changes the generated frequency data according to the amount of tilt of the joystick. It is therefore possible to input various sounds in tone using a limited number of switches. The frequency data stored in the video game machine is read later to be converted into audio signals, and outputted from a speaker incorporated in a CRT display. When a melody based on the inputted sound coincides with a predetermined melody set, the video game machine makes various changes in the progress of the game. For example, a hero character can be warped to a position that is different from the present position, or provided with various items.

A printed circuit board, having a plurality of via-holes provided in an area where circuit elements are arranged, includes a thermally conductive material having thermally good conductivity, for example copper, and the thermally good conductive material is formed in an inner wall of each of the plurality of via-holes. Each of the plurality of via-holes has, for example, a circular shape, and is arranged in the form of hexagonal or triangular lattice in the area where the circuit elements are arranged. Further, preferably, a diameter of each of the plurality of via-holes is equal to a hole pitch having an allowance .+-.0.3 mm. According to above structure, it is possible to provide a plurality of via-holes per unit area with high density on the printed circuit board and to improve the thermal conductivity of the printed circuit board by effectively radiating the heat generated from the circuit elements.

In a method of making a multilayer wiring board having a substrate and a wiring pattern formed in the substrate, base films are stacked in a predetermined direction to form a stacked film structure. Each base film includes thermoplastic resin. Pressure and heat are applied to the stacked film structure from its both sides in the stacked direction so that the base films are joined together to form the substrate. At least one of the base films is a combined film including a fiber sheet. Both sides of the fiber sheet are covered with the thermoplastic resin in such a manner that air space remains in the fiber sheet.

An alternator has a rectifier converting an alternating current to a direct current. The rectifier has a heat sink and rectifying elements. The sink has front and rear surfaces opposite to each other along a depth direction. The sink has holes each extending along the depth direction. Each element has a disk disposed in one hole and a semiconductor pellet attached to the disk. Each disk has upper and bottom surfaces opposite to each other along the depth direction. Each pellet is disposed on the upper surface. A contact surface of each disk is in contact with the sink. A position of the upper surface of each disk is placed between the first and second surfaces of the heat sink. A range of the contact surface of each disk is within a range between the upper and bottom surfaces of the disk.

A plurality of film insulators having conductive patterns that are formed on surfaces and conductive vias that pass through the film insulators in the direction of thickness are stacked together and collectively subjected to pressure and heat to be formed as a single unit. On one outermost layer of the multilayer board that has been thus formed, a plurality of connection terminals are exposed to the outside, connection bumps of an LSI chip being secured to these connection terminals. On the outermost layer of the opposite side, a multiplicity of metal pads are provided, and a solder ball is secured on each metal pad to form a ball grid array (BGA) structure for connecting to a motherboard.
