Title: Controller incorporating memory data protection circuit
Inventor: YOSHIMATSU MUTSUO
IPC: G06F12/14
Filed: 1985-07-23
Abstract: PURPOSE:To protect data on a memory from destruction when runaway occurs in a CPU by inhibiting the memory access before an access is given to the released address of a data protecting circuit in a writing mode. CONSTITUTION:A data protecting circuit 6 consists of a latch circuit 10 and a negative AND gate 11. The memory write control signal 12 is usually kept at H and the gate 11 has no actuation. The memory write signal WE' is set under a write unable state. Under such conditions, the pulse is applied to a clear terminal 13 of a latch circuit 10 with the data write release signal. Thus the signal 12 is set at L and the signal WE' is validated. Then an access is given to a memory by a memory access signal and the signal 12 is reset to H. Thus the memory access is inhibited in case said procedure is not carried out. As a result, the memory can be protected against a wrong writing action and the reliability of data is improved.

Filed: 1995-06-29
Abstract: PURPOSE:To lessen the dislocation when a tensile load is applied and enlarge the fracture load by forming a tapered hole in a gripping metal piece in such a curvature that the taper angle increases continuously from the inlet to the hole toward its bottom. CONSTITUTION:By a bonding resin 4, an FRP member 2 is joined with an inward widening tapered hole provided in a gripping metal piece 1 which has undergone a die separation processing and slided on the taper surface 3 by a tensile load P, and contacting pressure is applied from the peripheries by a wedge effect generated with this motion.

Abstract: PROBLEM TO BE SOLVED: To improve function by a method wherein an overflow edge circumferentially zigzagging in the semidiametral direction in the planate shape is provided at the periphery of an induction plate provided at the circumference of an opening at the upper end of a water intake-drainage pipe. SOLUTION: A faucet member 10 is constructed by erecting a labyrinthine overflow edge 20 at the periphery at the upside of a flangelike induction plate 12 provided at the front end of a water intake-drainage pipe member 11. For the overflow edge 20, while large diameter edge parts 21 are provided at specified angular intervals at the outer diametral part of the induction plate 12, small diameter edge parts 22 are provided respectively at positions at the diameter smaller by a specified amount corresponding to parts being devoid at the edge part 21, and a shape zigzagging in the radial direction as seen in the planate view is formed by connecting each of corresponding ends of the edge parts 21 and 22 with an edge part 23 in the diametral direction.  Then, the inside of the overflow edge 20 of the induction plate 12 is formed in a funnel-shaped form smoothly connecting at a specified curvature to an opening of the pipe 11. As the overflow edge is formed in a zigzagging shape, the overall length becomes longer than a circular overflow edge, and thereby the amount of water intake and drainage can be increased while reducing cost and furthermore, surface warm water can be taken efficiently.
