Title: Access control system of dynamic memory
Inventor: MIZUTANI MOTOHARU
IPC: G11C11/406
Filed: 1985-06-26
Abstract: PURPOSE:To minimize a drop in an access speed by giving an access with priority during the timer period of a timer activated in synchronization with an access request signal from the outside and accepting a refresh request and the access one from the outside in the order of arrival other than said timer period. CONSTITUTION:A refresh timer 1 generates a refresh request signal REF by the prescribed period, while a refresh counter 2 advances the value of a refresh address signal RFAD by '1' ROW and supplies it to a controller 3. It selects the refresh address signal RFAD so as to output it as a memory address signal MAD with respect to a DRCM4, outputs strove signals RAS and CAS, and refreshes the memory contents at a row address specified by the signal RFAD. When an access request signal REQ is inputted, the address signal transmitted to an address bus 6 in terms of time division is supplied to a DRAM4 as the memory address signal MAD, and data at an address to be accessed is written or read.

Title: Carrier for electrophotographic development
Inventor: IZAWA MORIYASU
IPC: G03G9/10
Filed: 1984-07-06
Abstract: PURPOSE:To provide a titled carrier which has the strength to the extent of obviating the generation of particle breakdown, improved fluidity and stabilized characteristic of the surface condition by consisting essntially of said carrier of magnet composed of a spherical material having 1.0-3.5g/cc apparent density, 10<6>-10<10>OMEGA.cm specific resistance and 30-500mum average grain size. CONSTITUTION:The reason for using the magnetite as essential component lies in that a magnetic brush is made softer and that the image is less roughened. Brittle structure is resulted from excessive bulkiness and the magnetic brush collapses gradually during use if the apparent density is <1.0g/cc. The density is too high and the good image characteristic is not obtainable conversely if the apparent density exceeds 3.5g/cc. The image density decreases and the image characteristic is poor if the specific resistance exceeds >=10<10>OMEGA.cm and the image characteristic is too hard in contrast at <10<5>OMEGA.cm. The carrier is too fine and suspends and is thus inadequate for being compounded with a toner for electrophtographic development if the average grain size is <30mum. The carrier is too rough and the image characteristic is poor if the average grain size excceds 500mum.

Title: Heat recovering device of skid cooling water of ingot heating furnace
Inventor: SHIODA KUNIO
IPC: F01K27/02
Filed: 1979-10-31
Abstract: PURPOSE: To recover waste heat without various defects  in the case of a boiler by heating the skid cooling water of an ingot heating furnace to high-temp. water without evaporating and using the same in the boiler and vaporizing a low b.p. heating medium and driving expansion turbines.  
     CONSTITUTION: Cooling water in a water storage tank 20 is admitted via an inlet side manifold 7 into the skid posts 9a in a heating furnace 3 to cool water cooling pipes 5 and cool the skids 4 in contact therewith. The cooling water is heated to hot water to about 98°C which is then taken out from the skid posts 9b and enters a carburettor 23 via an outlet side manifold 11. In the carburettor 23, Furon which is a heating medium of a low b.p. is heated and evaporated through heat exchanging and an expansion turbine 25 is rotated by the evaporated Furon to drive a generator 26. The hot water heat exchanges with Furon and is thereby cooled, thence it returns again into a storage tank. Since no boiler is used for the energy recovery device, there are no maintenance and inspection of boilers nor any economical defect such as constant stationing of boiler engineers, thus the heat energy of the cooling water of the skids may be recovered.
