In a game system, a server apparatus (3) that communicates with a plurality of game devices (1) stores play data elements for a plurality of players and public IDs for identifying a plurality of players in a latest play data table (T1) and a public ID table (T2). The server apparatus (3) transmits to a mobile terminal (4), which is being used by a player, information depending on latest play data elements stored in the latest play data table (T1), the latest play data elements belonging to other players who have been registered with the personal relationship table (T3) as a friend of the player possessing the mobile terminal (4). Upon receiving a public-ID-change request from a mobile terminal (4), which is being used by a player, the server apparatus (3) changes the public ID of the player stored in the public ID table (T2).

A mobile crushing system is for crushing inputted objects and dropping the crushed objects directly into an ore path. The mobile crushing system includes a crusher vehicle on which a crushing device for crushing the objects is mounted and which includes carriers, and a feeder vehicle on which a transfer device for transferring the objects to the crushing device and which includes carriers. The crusher vehicle and the feeder vehicle travel independently and include a crusher-side connecting portion and a feeder-side connecting portion that are connected to each other. During crushing operation, the ore path is interposed between the crusher vehicle and the feeder vehicle in the front-rear direction.

A switching power supply device includes: a switching element connected through a primary winding of a transformer to an output end of an input rectifying/smoothing circuit that rectifies and smoothes an alternating current input voltage and outputs a direct current input voltage; an output rectifying/smoothing circuit that rectifies and smoothes a voltage induced in a secondary winding of the transformer and outputs a direct current output voltage; and a control circuit that controls ON and OFF of the switching element. The control circuit includes an overvoltage protection circuit that detects a voltage corresponding to the direct current output voltage and a voltage corresponding to the alternating current input voltage, outputs an overvoltage operation prohibition signal for prohibiting ON and OFF operations of the switching element when the voltage corresponding to the direct current output voltage rises to a first threshold value or more, and releases the overvoltage operation prohibition signal when the alternating current input voltage drops and the voltage corresponding to the alternating current input voltage falls down below a second threshold value.

An adaptive equalization circuit (105) operates for PR-equalization of the reproduced signal that is subjected to an A/D conversion by an A/D converter (103) and shaped by a waveform shaping circuit (104). An ideal-waveform generation circuit (110) generates an ideal waveform that corresponds to the reproduced signal that is binarized by a Viterbi-decoding circuit (108). A mark-length/space-length calculation circuit (112) calculates the actual mark length/space length relative to the mark length/space length to be formed, based on the equalization error that arises when the ideal waveform assumes a central reference level as calculated by an equalization-error calculation circuit (111) and the intervals of polarity inversions of binarized data detected by a 0-cross detection circuit (109). A system controller (114) adjusts the edge shift quantity of the recording waveform when forming a mark based on the calculated mark length/space length.

In a semiconductor device manufacturing method in which a wafer formed with devices in a plurality of areas sectioned by a plurality of streets formed in a lattice-like pattern on the front surface is divided into the individual devices along the streets, when the wafer is divided into the individual devices by exposing cut grooves formed along the streets by a dicing before grinding process, a rigid plate is applied to the front surface of the wafer and an adhesive film is attached to the rear surface of the wafer. Thereafter, a separation groove forming step is performed in which a laser beam is directed to the adhesive film along the cut grooves form the dicing tape side applied with the wafer attached with the adhesive film to form separation grooves in the adhesive film along the cut grooves.

A method for picking up a device stuck with an adhesive film includes an tape expansion step for expanding a dicing tape to increase intervals between devices and between adhesive films by pressing an area between an inner diameter of the annular frame of the dicing tape and the wafer by means of an expansion member with the annular frame held; and a picking-up step for picking up the device and the adhesive film from the dicing tape. A relative shifting rate between the expansion member and the frame holding means is set to 100 mm/second or more when the expansion member and the dicing tape are brought into abutment against each other in the tape expansion step, and the increased intervals between the devices and between the adhesive films are each set to 100 μm or more.
