Abstract: PROBLEM TO BE SOLVED: To provide a power circuit pattern wiring width generation system and method for automatically performing calculation of a power circuit pattern wiring width, instead of conventional calculation of the wiring width by a worker, when forming a power circuit pattern on a printed circuit board.
SOLUTION: A table showing the relation between the power supply capacity and the wiring width of the power circuit pattern is installed in the system beforehand, and then the pattern wiring width is calculated from data on part connection information, wiring length, the number of layers, and the power supply capacity, as well as from the the table.

Abstract: PROBLEM TO BE SOLVED: To distribute a clock to a circuit which performs two-way data transmission through a data transmission line without being restricted by the length and transmission frequency of the data transmission line in . SOLUTION: A clock transmission line 41 for transmitting the clock to data transmission circuits 1 and 2 has the same characteristic as that of the data transmission line 3, one end of the clock transmission line 41 is connected to an input-output port P1 of a clock transmission control part 42, and the other end is connected to an input-output port P2 of the clock transmission control part 42 via a clock input port 15 of the data transmission circuit 1 and a clock input port 25 of the data transmission circuit 2. The length of the clock transmission line between the clock input ports 15 and 25 is set in the same length as that of the data transmission line 3. The clock transmission control part 42 transmits the clock to the clock transmission line 41 so as to transmit the clock in the same direction as a data transmission direction shown by a transmission direction control signal Sc and makes the clock returning from the clock transmission line input to a termination resistor 43 with the same value as that of a characteristic impedance of the data transmission line.

Abstract: PROBLEM TO BE SOLVED: To detect opening with stable operation without increasing power consumption. SOLUTION: A saturated voltage between the emitter and collector of a transistor 8 is made smaller than the sum of a cutoff voltage between the emitter and base of a transistor 3 and the forward voltage of a diode 6, when a current flowing to the transistor 8 is decreased, a current flowing to the collector side of the transistor 3 is detected by photodiodes 4-1 and 4-2 of a photocoupler and opening detecting signals are outputted from opening detecting signal sending terminals 11-1 and 11-2.

Abstract: PROBLEM TO BE SOLVED: To quickly measure a coplanarity by a low-cost installation.
SOLUTION: When a height of a solder ball (an object to be measured) 20 on a wiring board 22 is measured by a laser displacement sensor 1, one end face of a pin (a contacting piece) 21 arranged so as to correspond to each solder ball 20 is brought into contact with the solder ball 20, and the other end face of the pin 21 is measured by the sensor 1. The pin 21 is held by a jig mainframe 23 so as to be movable in the up-and-down direction, and it is moved up and down according to a height in a top part of the solder ball 20. The upper and lower end faces of the pin 21 are formed to be flat, and the height in the top part of the solder ball 20 is reflected faithfully so as to be measured surely by the sensor 1. Consequently, even when a shape of the object to be measured is spherical, the coplanarity in the top part of the object to be measured is measured easily when the pin 21 is brought into contact with the object to be measured.
