Patent JP-H03262191-A (JP)
Title: Solder coating of printed board
Inventor: ASANO SHOZO
IPC: H05K3/34
Filed: 1990-03-13
Abstract: PURPOSE:Not only to enable a solder coat to be uniformly formed but also to prevent solder bridges from being formed between lands by a method wherein cream solder composed of liquid or paste flux and solder powder is applied onto the lands of a printed board, and then the cream solder is fused by heating to form a solder coat layer on the lands. CONSTITUTION:Cream solder 3 composed of 25-80% by weight of liquid or paste flux and 75-20% by weight of solder powder is applied onto the lands 2 of a printed board 1, and the cream solder 3 is fused by heating to form a solder coat layer 4 on the lands 2 of the printed board 1 keeping the solder applied side of the board 1 facing downward. At this point, if the cream solder 3 is applied uniform in thickness, solder can be uniformly attached to the part where it is applied after it is fused, and solder bridges are hardly formed between the lands even if they are arranged at a small interval when flux contained in the cream solder is increased in content. Furthermore, when the cream solder 3 is fused after keeping the cream solder applied side of the board 1 facing downward, solder is prevented from sagging from a solder applied part and being joined to the solder attached to an adjacent solder applied part even if the applied solder is a little too much in quantity.

Title: Safety device for reclaimer
Inventor: TORII KEIICHIROU
IPC: B65G65/20
Filed: 1985-03-27
Abstract: PURPOSE:To prevent tumbling by allowing a raising/felling rope, which is mounted at a part of the swirling member installed with vertical rotatability with respect to the other parts, to pull up part of the swirling member, when the rope tension is increased by overloading to be followed by upward rotation, and thereby admitting downward rotation of the boom. CONSTITUTION:In the event of overloading on the tip end of a boom 3, it is going to fell a movable mast 5 rightwise with the aid of a rope 4, which will increase the tension of a raising/felling rope 9 to cause lift of the rear 12a of a swirling member 12 against the action of a damper cylinder device 18, and now said rear 12a turns upward round a coupling shaft 17 to allow the rope 9 to move nearer the mast 5, so that the mast turns toward the boom 3 to permit sinking rotation of the boom 3. Accordingly the boom 3 escapes while rotating downward, so that the overload is not transmitted to the front part 12b of the swirling member 12 and a traveling object to contribute to prevention of the whole reclaimer from tumbling as well as the boom 3 from being folded. Thus the safety is ensured.

Title: Superconducting logic circuit
Inventor: HATANO YUJI
IPC: H03K3/38
Filed: 1988-03-16
Abstract: PURPOSE:To prevent errorneous switching from occurring even if an operating point crosses the internal mode boundary of a threshold characteristic curve by fetching symmetrically output currents from superconducting loops which are included in magnetic flux quantum interference type gates and which consist of Josephson junction and inductances. CONSTITUTION:The output currents are set to be fetched symmetrically from respective superconducting loops which are included in the magnetic flux quantum interference type gates 11 and 112 and which consist of the Josephson junctions 251-253 and the inductances 221-224 and 231-234. Thus, the gates can be prevented from being erroneously switched from a superconducting state to a voltage state by impulse when the operating point crosses the internal mode boundary of the threshold characteristic curve when the polarity of an AC power voltage is inverted, and an operation is stabilized. Since errorneous switching is impervious to occur, the transition part of an AC power cycle can be shortened and the clock cycle of a logic circuit can be shortened.
