Title: Fail-safe controller
Inventor: YAMAGUCHI SHINICHIRO
IPC: G06F11/30
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To obtain a means which can processes an alternating signal unintentionally when an arithmetic processing program is generated or modified by making an output part output a specific signal pattern or the alternating signal only when control output data of a control arithmetic part specifies a danger- side output. SOLUTION: When an output signal 114 is outputted, a counter 1121 of an output monitor part 112 finds the alternating signal rising and counts the frequency of alteration of the alternating signal. The counter 1121 has its value reset when a control cycle start trigger 13 is inputted by one pulse. If the control arithmetic part gets out order and the control cycle start trigger 13 is delayed to cause the value 1125 of the counter 1121 to exceeds the upper-limit value 1124 of a counter upper-limit value setting register 1120, a large/small comparator 1122 outputs an output stop signal 1126. An output control part 1123 stops the alternating signal of the output signal and outputs a fixed-value signal as a control signal 2. Namely, when the control cycle start trigger 13 is delayed, a safe-side output is outputted.

Title: Method of connection between coil and terminal
Inventor: WATANABE NAOYUKI
IPC: F16K31/06
Filed: 1989-04-04
Abstract: PURPOSE:To prevent the occurrence of any malfunction due to expansion at time of fusing as well as to improve the extent of quality by bending the edge of a metal piece turning to the tip side of a terminal into a flange form in advance. CONSTITUTION:An edge part 8 being situated correspondingly with a tip part 4' of a terminal 4 in a metal piece 7 is bent in a flange form in advance. Next, in this state, if fusing takes place, heat due to this fusing is hard to be transferred to the edge part 8 bendingly projected to this flange-form metal piece 7, so that a tip part 4' of the terminal 4 being situated correspondingly with the edge part 8 is hard to be fused. Consequently, a fusing part of the terminal 4 is dammed up at the side of the unfusible tip part 4', therefore such a fusing expansion as projecting in the longitudinal direction of the terminal from the edge part 8 is checked, thus the fusing expansion in a direction orthogonal with the longitudinal direction is preferentially performed. Accordingly even in the case where the tip part 4' of the terminal 4 comes nearer to an inner wall of a metal case 5 as in a solenoid valve 1, such a possibility that the fusingly expanded terminal 4 might come into contact with this case 5 and be short-circuited can be thus prevented.

Filed: 1976-07-19
Abstract: A pierce-type contact element for use with a connector for a multi-conductor flat cable having a plurality of parallel insulated round wire conductors, each contact element having a circuit connecting terminal and a bifurcated part nested within the connector. The bifurcated part provides a pair of sharply pointed tines the opposed inner edges of which are spaced apart a distance less than the diameter of the wire conductor and act to slice through the conductor insulation to electrically engage opposite sides of the conductor wire. The tines are reversely bent to provide the same with parallel portions which are offset from one another along the longitudinal axis of the insulated conductor. The opposed inner edges of the tines are provided with sharply cornered cutting edges which respectively bite into and make contact with opposite sides of the conductor wire at two points spaced lengthwise of the wire. The parallel relatively offset portions of the tines of the contact element place the conductor under tension in the region of its connection to the contact element, the force of which tension serves to hold the contact element in secure electrical connection with the conductor.
