Title: Soldering pattern
Inventor: HASHIMOTO MITSUO
IPC: H05K3/34
Filed: 1998-12-07
Abstract: PROBLEM TO BE SOLVED: To facilitate filling of cream solder, improve the quality of soldering after soldering and increase adhering amount of cream solder for increasing the mechanical strength. SOLUTION: This soldering pattern is provided comprising a plurality of lands 2 corresponding to lead legs for mounting a electronic component having a plurality of lead legs on a board 1. Lads 2 are formed at intervals in a direction perpendicular to the longitudinal direction and form a shape of which one end 2a in the longitudinal direction has a width smaller than a width W1 of the other end 2b. Thereby, a part near the range of the land 2 in the longitudinal direction can be shortened, and when there is oozing of the cream solder, it will not contact an adjacent land 2, and filling of cream solder is facilitated. Furthermore, since the distance from a land I1 can be made larger than in the conventional method, solder bridges and short circuit and the like by solder can be prevented. As a result, the quality of soldering can be improved.

IPC: G05F1/30
Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To develop a circuit system for reducing the size and weight of a heavy transformer. SOLUTION: When power is alternately inputted to two transformers by switching a commercial AC power supply 3 itself at a high speed (10 to 100 kHz), voltage values corresponding to the ratio of the numbers of windings are alternately outputted from the two transformers, but since the output sides of these transformers are connected in parallel, a sine wave of continuous commercial frequency can be obtained as a synthetic output. Since the switching system is adopted, the size of the transformer can be reduced in accordance with the increment of switching frequency and the weight can be reduced at least to 1/3.21 at 10 kHz and maximum to 1/22.4 at 100 kHz.

Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To form a uniform magnetic film on a ground part of an object member by grinding an object face of the object member with non-transferring part of cutting edge abrasive grain of a rotary grinding stone. SOLUTION: By rotating a grinding stone 50 by driving a motor 52 and also operating a moving means 54 in the direction of Z, the motor 52 and the grinding stone 50 are lowered in the direction of Z1. Thus, a tapered part 22a, which is almost V-shaped in section of a grinding part 22, drills vertically into an object member 10. Consequently, a groove 12 coincident with the tapered surface 22a in shape is formed to the object member 10. And, if the rotary side face 23 of the grinding stone, rotating and cutting in the radial direction of the grinding stone 50, grinds an inclined face 14 in the direction of X, the grinding stone is less abraded and the inclined face 14 can be ground in less surface roughness.

Abstract: PURPOSE:To prevent the early abrasion of a seal member at low temperature by providing a pressure adjustment permitting/inhibiting means, which permits the pressure adjustment in case that the seal temperature gotten by a seal temperature getting means is more than the tolerable temperature, and inhibits the pressure adjustment in case that it is lower than the tolerable temperature. CONSTITUTION:In case that a pressure adjustment permitting/inhibiting means 56 is in the mode of permitting pressure adjustment while a vehicle is not running even if seal temperature is low, if the seal temperature is low and the vehicle is running when the command to do pressure adjustment is issued, the start of pressure adjustment is inhibited, whereby a seal member is kept at atmospheric pressure. Next, if the vehicle is not running even if the seal temperature is low, the start of the pressure adjustment is permitted, whereby it turns out that the seal member is placed under high pressure. But, then, if the vehicle starts running, the pressure adjustment is inhibited if the seal temperature at that time is low. If the pressure adjustment is started, a passage opening/closing device 80 breaks a specified part passage from a tire chamber 6, and the seal member is placed under atmospheric pressure.

Abstract: PROBLEM TO BE SOLVED: To provide an ink-jet printer enabling an auxiliary operation such as a control over formation of satellite drops at the time of discharge of ink drops without increasing a count of driving signals, etc. SOLUTION: Two piezoelectric elements 116a, 116b of mutually different natural frequencies are set for each nozzle 118. The same driving signal is applied to these two piezoelectric elements 116a, 116b, whereby ink drops are discharged by the piezoelectric element 116a of a shorter natural frequency, while the piezoelectric element 116b of a longer natural frequency is acted to restrict generation of satellite drops at the discharge of the ink drops. A trail of the ink drop can be cut at an early stage and generation of satellite drops can be restricted. Different driving signals are not applied separately to the two piezoelectric elements 116a, 116b, but the single driving signal is used to drive the two piezoelectric elements. A count of necessary driving signals is reduced as a whole.
