Abstract: PURPOSE:To attain high speed differential readout with a simple constitution, by giving the difference to mutual conductance between a memory cell and a dummy cell. CONSTITUTION:Information 1 is written in a dummy cell DM0 or the like so as to always discharge a digit sense line DS toward a low level at the readout where the line DS is charged to a high level by precharging via a transistor (TR) Qgs, and the difference is given to the mutual conductance between the cell DM0 and cells M00, M01- so that the voltage change in the line DS takes place almost at an intermediate level between the time change of both voltages on the digit sense lines D0, D1. Thus, in reading out information 0 or the like of the cell M00, the lines D0, D1 remain the high level, and in setting a sense a sense amplifier SA when the line DS is discharged to attain a suitable level, the line DS is discharged in high speed and the information 0 is read out quickly.

Abstract: PURPOSE: To improve durability of ignition plug against heat as well as inflammability and combustibility of mixture, by producing mixture by injecting fuel onto the  inner wall surface of combustion chamber, and injecting plasma gas into the mixture from a plasma injection type ignition plug.  
     CONSTITUTION: When the piston comes near to the top dead point, fuel is injected into combustion chamber 2 from fuel injection valve 3 and forms mixture through its evaporation. Simultaneously, a high voltage is produced in secondary coil 24b by the function of cam 21 and spark discharge is caused in discharge space 11. Here, since insulation in discharge space 11 is ruptured, a relative low voltage can cause spark discharge and the spark discharge is maintained by power source 31 of low-voltage power circuit 20b. The plasma gas thus produced by the spark discharge is injected into combustion chamber 2 from port 12 for igniting and combusting mixture.

IPC: B22D27/04
Filed: 1995-03-30
Abstract: PURPOSE: To reduce the number of working processes and to prevent the development of trouble, such as deformation, crack, by beforehand arranging an exothermic material to the position in a mold corresponding to the position softening a cast product and generating the heat of the exothermic material at the time of cooling after pouring the molten metal into the mold to partially delay the cooling of the cast product. CONSTITUTION: The molten metal is poured into the mold composed of a sand mold 10 to form a pulley 51, and at the time of cooling the pulley 51 as the cast product, the steel structure at the tip part 51a of a shaft part of the pulley 51 becomes low perlite and high ferrite by generating the heat of the exothermic material M, and then, this part is softening-annealed. Therefore, the cast product can be cooled and solidified in the remained condition in the mold and is unnecessary to take out from a mold. Further, since the take-out of the cast product is made to be unnecessary, the deformation of the cast product is not developed and the loss of the thermal energy is little. Further, since the sand mold 10 is used, the cooling speed is delayed and the chilled structure is not formed on the surface layer part of the cast product.

Abstract: PURPOSE:To give the partially different properties by only the heat treatment, by splitting up the material to be quenched into plural parts with grooves, by heating each split part to different quenching temperature, and then, by quenching each part at the same or different cooling speed. CONSTITUTION:The grooves 2, 2, are formed in the material 1 to be quenched, and the insulator 3 is filled up in each groove 2. Thus formed split parts, that is, the part between the grooves 2 and 2, and the part between the groove 2 and the end face 4, are heated up to respectively different temperature. Besides, the partition plate 5 is attached closely to the groove 2, and each part is independently cooled by different cooling method, that is, water cooling, air cooling, etc. Hereupon, because of the existence of the partition plate 5, each split part is prevented from cooling by the cooling medium for the adjoining part. Thus, the different parts of a monolithic product can be quenched under the different quenching conditions, and are endowed with different physical properties.
