Abstract: PURPOSE:To early detect the runaway of a processor and to prevent the abnormal actions by previously setting a program area or other areas except the program area for each memory chip and producing an abnormality signal via the processor when the fetch is detected in an area except the program area. CONSTITUTION:A fetch detecting circuit 2 detects the fetch received from a control line of a processor 1 and at the same time the address signal of the processor 1 is latched by an address latch circuit 3. A higher rank of the address latched by the circuit 3 is given to an access decoder 5, and the chip enable output serving as the decoding output for chip selection of a memory 4 is produced. An area setting part 6 sets the program area corresponding to each chip of the memory 4 and the areas except the program area after discriminating these areas from each other and informs a selector 7 a fact that the processor 1 detected the fetch against the memory 4. Then no chip selection signal is produced, and an abnormality detecting circuit 8 produces an abnormality signal by the timing of the chip enable output.

Title: Cylinder device
Inventor: FUJINAMI FUTOSHI
IPC: F25B9/00
Filed: 1987-08-20
Abstract: PURPOSE: To prevent abrasive powder from being caught between the piston end face and the cylinder end face by increasing the interval between them on the side opposite to the conduction port of the cylinder where the abrasive powder is deposited easily and decreasing the interval on the conduction port side. CONSTITUTION: Piston end face 22 of a compression piston 21 is inclined against the central axis such that the interval to the cylinder end face 9 is longer on the opposite side than on the conduction port 7 side. Since a large gap can be kept at top dead center even if abrasive powder 11 is shifted to the cylinder face on the side opposite to the conduction port 7, the abrasive powder 11 can be prevented from being caught between both end faces. Gap on the conduction port 7 side is minimized when the compression piston 21 is located at top dead center and average gap between the piston end face 22 and the cylinder end face 9 is set equal to a conventional value.  A cut 23 is made at the forward end on the conduction port 7 side of the compression piston 21 so that the conduction port 7 is not closed by the side face of the compresstion piston 21 even if it is located at top dead center.

Filed: 1992-07-13
Abstract: PURPOSE:To prevent the access of persons to a dangerous area by housing a smelling material together with gases for fire extinguishing into a container for housing these gases and exhalating this material simultaneously with radiation of the gases for fire extinguishing. CONSTITUTION:The gaseses for fire extinguishing, for example, CVO2 and N2, are housed into the high-pressure gas container 1. A nozzle 3 of a piping 2 exists in a fire object area and radiates the gases from the nozzle 3 by the operation of a trigger 4. The smelling material is housed together with the gases into this container 1. This smelling material is radiated together with the gases for fire extinguishing from the nozzle 3 to the objective area. The smelling material may be any of solid, gas and gas and is preferably the material which does not generate a chemical reaction with the gases for fire extinguishing. The material is required to be fine powder in the case of the solid. The material is preferably radiated from the nozzle 3 simultaneously with the radiation of the gases for fire extinguishing or in the initial period of the radiation in the case of the liquid and the gas. Then, the smelling material is exhalating in the area where the fire breaks out hand, therefore, the persons evade the dangerous gas area during the firing and after the fire extinguishing by the smells thereof. The danger is thus prevented.
