Abstract: PURPOSE:To accelerate a speed and to reduce power consumption by forming a sense amplifier of a reading circuit for reading information of a memory cell of a plurality of sense circuits connected in parallel. CONSTITUTION:A first sense amplifier having P-channel transistors Q1-Q3 and N-channel transistors Q4-Q6 and a second sense amplifier having P-channel transistors Q8-Q10 and N-channel transistors Q11-Q13 are connected in parallel between a bit line B and a bit line/B. A first amplifier has small power consumption, a second amplifier has large amplification factor, and hence the first, second amplifiers are activated to be accelerated at its speed at the time of reading. Since an amplification signal of the bit line B and the bit line/B can be held only by the first amplifier having the small power consumption after the reading is finished, power consumption can be reduced.

Title: Drum carrier vehicle
Inventor: TANAKA YOSHIO
IPC: B62B3/10
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To make a contact location between a drum and a drum raising up cylinder substantially unchanged when a laid down drum is raised up by providing the drum raising up cylinder which is rotatable elastic roller, is reinforced in pressure contact frictional force with a barrel of the drum and prevents slip. SOLUTION: When a drum raising up cylinder 8 as a hitting member is raised by H, a drum 4 is inclined by an angle α. In this case, because the drum raising up cylinder 8 is one which is reinforced in pressure contact frictional force with a barrel of a drum and prevents slip, contact area is large and a contact location between the barrel of the drum 4 and the drum raising up cylinder 8 is remained unchanged. When the drum raising up cylinder 8 is further raised and center of gravity of the drum 4 reaches a standing support point 4d, the drum raising up cylinder 8 advances by a distance F as compared with its original location and does not retreat for the time. Therefore, because weight of the drum 4 does not work so as to push a carrier vehicle backward, a worker can easily perform a work, even if one-way braking device is not provided.

Abstract: PURPOSE:To inhibit runaway of fish with mouth-cutting by prolonging on-time in driving control stepwisely from zero and gradually winding up a spool with operating electric voltage to on-off applying on a motor in pushing a switch for winding up. CONSTITUTION:A fish is caught and pushes a switch 8, then a control means 9 recognizes the catching, thus a starting signal is arisen in a timer means 5 and a pulse-duty ratio controlling means 7 and a pulse of on-time and off-time as an initial value is outputted by the controlling means 7 to a motor-driving means 4, then a motor 3 is driven by the driving means 4 in the same timing. Thus, simultaneously a count-up is started in the timer means 5 and an overflow signal is arisen in said means after a fixed time. Then, the fixed time is outputted in a reference value-outputting means 6, thus the on-time is added and the off-time is subtracted in the controlling means 7 and resultant pulse is outputted to the driving means 4. Said processes are repeated in every overflows of the timer means 5 till the on-time attains to 100 %.

Abstract: PROBLEM TO BE SOLVED: To obtain a resin composition in which a larger amount of a liquid substance has been incorporated without detriment to productivity and which is excellent in appearance, light resistance, and mechanical properties by mixing a thermoplastic resin with a liquid substance at a specified temperature and melt-extruding the mixture. SOLUTION: A resin composition containing a thermoplastic resin (A) and a liquid substance (B) which exists in a liquid state in the temperature range of 25 to 300 deg.C is produced in the following way. First, A is mixed with B at a temperature selected from temperatures ranging from the temperature at which B begins to exist in a liquid state from 300 deg.C to lower the Tm or Tg of A by 10-200 deg.C. When A is a crystalline resin, its melting point (Tm) is used as the criteria, while, when A is an amorphous resin, its glass transition temperature (Tg) is used as the criteria. Next, the resultant mixture is melt-extruded at 150-300 deg.C with a melt extruder. Component B is a component used to impart desirable properties such as flame retardancy to the thermoplastic resin and is desirably a non-polymerizable polymer additive.  Especially, a flame retardant, a heat stabilizer, a plasticizer, or a light stabilizer is desirable.

Title: Operation method of refuse burning equipment
Inventor: SAITO JUNICHI
IPC: F23G5/00
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To provide an operation method of refuse burning equipment capable of stably supplying a proper amount of refuse into a burning furnace in response to the required amount of heat produced in the burning furnace. SOLUTION: In refuse burning equipment for supplying refuse into a burning furnace using a refuse supply crane, a pressure detector 3a and a backet opening detector 3b are arranged on a backet 3 provided on the refuse supply crane. A stress ratio of refuse is estimated on the basis of the amount of a change in an indicated value on the pressure detector when the opening of the backet holding the refuse is narrowed. The produced heat amount of the refuse is estimated from a correlation equation between the preestimated produced heat amount of the refuse to control the supplied heat amount of the refuse.  The foregoing correlation equation is corrected by reversely estimating the produced heat amount of the refuse during combustion from the flow rates and temperatures of air, an auxiliary fuel, and cooling water applied to the refuse burning furnace, and the temperature and the dissipated heat amount of combustion exhaust gas.
