Title: Repetitive shearing and pressure-welding method of metal plate material
Inventor: NAKAGAWA TAKEO
IPC: B23K20/00
Filed: 1979-05-29
Abstract: PURPOSE: To firmly bond dissimilar metal plates such as pure copper and aluminum with minimum of hit marks, by imparting shearing pressure repeatedly so that the metal plate materials at the joining part may mutually bite into the other plate within its thickness, when bonding metal plate materials by overlapping.  
     CONSTITUTION: When bonding dissimilar metal plate materials, such as pure copper and copper alloy, and pure copper and aluminum, the plate materials 1, 2 to be bonded are overlapped together wholly or partly, and the overlap part is clamped by dies 3, 4. By opposedly providing upper and lower punches 7, 8 on die holes 5, 6, the plate materials 1, 2 are moved reciprocally in specified vertical stroke. In this case, shearing force is applied so that the upper plate material 1 may bite into the surface of the other plate material 2 when descending and that the plate material 2 may bite into the lower side of the plate maerial 1 when ascending, thus mutually to the plate materials 1 and 2 by a depth of (t). As a result of this, the boundary parts 12a, 12b and press-fit parts 13, 13' are heated to high temperature to form weld zones W, W', respectively, so that the plate materials 1, 2 may be firmly bonded without causing hit marks.

Abstract: PURPOSE:To enhance the responce and reliability of an automatic wiper, by providing such an arrangement that the oscillation of a diaphrgm due to the collision of rain drops is converted into an electrical signal with which the amount of rainfall is detected, and the wiper is driven in accordance with the result of the detection. CONSTITUTION:A piezoelectric element 2 and a vibration absorbing member 3 for absorbing vibration from a vehicle are secured to a diaphragm 1 to form a sensor section S. The surface of the vibrating absorbing member 3 remote from the diaphragm 1 is bonded to the outer surface of a windshield. When the diaphragm 1 is exposed to a rain and therefore oscillates, this oscillation is converted into an electrical signal by the piezoelectric element 2. This electrical signal is transmitted through an amplifier 4 to a comparator 5 in which the electrical signal is compared with a threshold value, and if the electrical signal is larger than the threshold value, the comparator 5 delivers a pulse signal to a counter 6. The counted value of the counter 6 is transmitted to a comparator 7 which actuates a wiper drive circuit 9 through a relay 8 and resets the counter 6 when the count value is larger than a set value.

Abstract: PURPOSE:To prevent adverse effects such as the disappearance, delivery delay, etc., of packet data without changing a protocol. CONSTITUTION:The header information of the packet data for which transfer is to be obstructed is held inside a judgement part 103 beforehand. When the held contents and the header information of the inputted packet data coincide, a gate circuit 106 is turned to an off state and the transfer of the packet data from other terminals is obstructed. Thus, since the header information is utilized, without changing the protocol, the adverse effects such as the disappearance of the packet data and the delivery delay, etc., are prevented.
