Patent JP-2000101222-A (JP)
Title: Printed wiring board and producing method therefor
Inventor: NOJIOKA SHINICHI
IPC: H05K1/11
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To provide a printed wiring board improved in the strength of soldering by preventing generation of solder bridges and further increasing the quantity of solder stuck on a land. SOLUTION: A land 1 to become the base of solder formation is star-shaped. Thus, since the length L2 of an outer peripheral part, where adjacent lands away for a distance L1 are most proximate, can be extremely reduced, possibility to generate a solder bridge can be lowered. Further, since the area of star- shaped land 1 is larger than the diamond-shaped land in the same size, the solder is stuck more than the quantity of solder to be stuck on the diamond- shaped land and the strength of soldering can be improved.

Title: Cr oscillation circuit
Inventor: HIGUCHI FUJIO
IPC: H03K19/0948
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To provide a CR oscillation circuit of high accuracy which can reduce the variance of frequency against the variance of power voltage by adding the pull-down or pull-up resistance to the inverter of the CR oscillation circuit. SOLUTION: An input terminal CLI is connected to an output terminal CLO via the feedback resistance Rf, the input capacitance Cin is connected between the terminal CLI and a ground terminal, and the pull-down resistance Rd (or pull-up resistance) is connected to the output terminal of a 1st inverter 2 respectively. When the resistance Rd is added, the input/output characteristic having the hysteresis characteristic is pulled by the resistance Rd in the direction where the threshold level VTL is set close to the power voltage VDD. Therefore, the fall of frequency can be suppressed by the control of the value of the resistance Rd. Thus a CR oscillation circuit of high accuracy never causes the variance of frequency against the variance of power voltage as long as the resistance Rd is set at the proper value.
