Title: Printed board for surface mounting
Inventor: ICHIMURA MORIKATSU
IPC: H05K3/42
Filed: 1990-07-31
Abstract: PURPOSE:To enable good soldering of components by a method wherein a solder reservoir consisting of a through-hole or a recessed part is formed on a pad for soldering use. CONSTITUTION:A solder reservoir 3 consisting of a through-hole is formed in the central part of a pad 2 for soldering use of a circuit pattern. A creamy solder is previously applied on the pad 2 by a printing method. At this time, one part of the creamy solder intrudes in the reservoir 3 and the amount of the previously applied creamy solder is given a margin by the amount of the solder which intrudes in the reservoir 3. When components, such as an IC or the like, are fixed at prescribed positions and the solder 7 is melted, an excess solder is sucked in the reservoir 3 by capillarity. In case the amount of the solder is rather little, the solder in the reservoir 3 is sucked out by a capillarity due to the gap between a part 6 to be soldered and the pad 2. Accordingly, the amount of the solder 7 between the part 6 and the pad 2 is adjusted in proper quantity by the solder in the reservoir 3 and the components are favorably soldered.

Title: Pid controller
Inventor: SAITO TADAYOSHI
IPC: G05B13/02
Filed: 1987-08-14
Abstract: PURPOSE:To automatically optimize the control parameter of a PID (proportion, integration and differentiation) controller with no intervention of an operator nor application of a test signal for fixture to a control subject, by using a controlled variable response form recognizing means, a controllability deciding means, etc. CONSTITUTION:A controlled variable response form recognizing function 4 contained in a control parameter auto-tuning function 3 of a PID controller 1 always monitors the target value SV and the controlled variable PV. The observation of the controlled variable is started at a time point when the control deviation exceeds a prescribed level after the variable PV is controlled to the value SV. Thus the extreme value of the PV is searched and said observation is through when the PV is controlled to the SV. Then the overshoot value, the attenuation coefficient and the synchronization ratio are obtained from plural obtained extreme values and their occurring time points. These obtained values undergo decision whether they are kept within each allowable range or not via a controllability deciding function 5. If so, the optimum value is decided for the control parameter. If not, a control parameter correcting function 6 is actuated. Thus the control parameter is automatically optimized.

Title: Agc circuit
Inventor: KATO TAKUJI
IPC: H03G3/30
Filed: 1990-07-30
Abstract: PURPOSE:To prevent an excess output signal automatically with respect to an input signal by devising the circuit such that a reference voltage of a comparator is increased when a gain of a variable gain amplifier is increased and the reference voltage of the comparator is decreased when the gain of the variable gain amplifier is decreased. CONSTITUTION:A variable resistor(2) is adjusted to decrease a control voltage resulting in decreasing a gain of a variable gain amplifier (1), then a level adjustment (8) detects it that the control voltage is decreased and lowers a reference voltage of a variable reference source (9). When the reference voltage of the variable reference source (9) is decreased, a limiter level (AGC start level) in the variable gain amplifier (1) is decreased. Thus, even when a large sound volume is caused amidst the listening of a listener at a small sound, the signal causing a large sound volume is limited by the variable gain amplifier (1).
