Abstract: PURPOSE:To reduce power consumption by calculating the discharging amount of particulates on the basis of a detected engine operating condition, integrating the particulate collecting amount of a filter, and controlling the operating time of an electric heater on the basis of the integration value thereof. CONSTITUTION:A trap main body 20 is divided into two systems flow passages 23, 24 are provided while interposing filters 21, 22, and shutter valves 25, 26 opened/closed by solenoid valves 27, 28 are arranged. Signals of an engine rotational speed sensor 36, and an engine load sensor 37 are inputted into a controller 38, and recovery demand for the filters 21, 22 is emitted so as to control the solenoid valves 27, 28 and an electric heater 31. In the controller 38, the discharge amount of particulates is read out from a map and integrated by means of the signals of the engine rotational speed and a load. When a prescribed tine passes, the required time for combustion of the particulates is read out on the basis of the integrated value, and the heater 31 is turned on for this time. Power consumption is thus reduced so as to reduce burden of a battery 39.

IPC: H01P1/12
Filed: 1988-07-15
Abstract: PURPOSE: To easily make a microwave switch compact by allowing or inhibiting the passage of a microwave between two waveguides according to whether or not a conductive core constitutes a coaxial waveguide part according to the position. CONSTITUTION: In a cross section of the microwave switch, a drawn-out type movable element T1 made of a dielectric material including the conductive core BC is arranged along the same axis crossing the axes of two waveguides G1 and G2 which are arranged, side by side, almost at right angles. Then the conductive core BC constitutes the coaxial waveguide part between the waveguides G1 and G2. Namely, both the ends E1 and E2 of the conductive core BC are in the same plane with the axes of the waveguides G1 and G2 at the position in the figure and the conductive core BC is therefore inside each waveguide by length nearly equal to a half of the internal size of the waveguide, so that the switch allows the passage of a microwave.  At an opening position, the movable element T1 is translated by a distance 'd' and the conductive core BC does not constitute the coaxial waveguide part between the waveguides G1 and G2.

IPC: G06F12/10
Filed: 1990-07-03
Abstract: PURPOSE: To perform high-speed memory read and write by providing a comparator for judging whether or not a memory location indicated by an address request is included inside the plural memory locations. CONSTITUTION: In order to process a new address request 001110, row bits inside the address request 8 and the contents of virtual/physical (CAMtag) 7 are compared. In this case, the row bits inside the address request 8 are 001 and the contents of the CAMtag 7 are 101 on the other hand. Thus, since the comparator 11 indicates that a CAM error is present, it means that the newly arrived address request 8 is for a row different from the row asserted at present. Then, when the comparator 11 indicates an error, registers 6 and 7 are updated. Thus, cache fill time is reduced and a valid write band width is enlarged.
