Filed: 1995-01-31
Abstract: PURPOSE: To stabilize the behavior of a vehicle by recognizing the partial high loading state when the vehicle speed is substantially zero and also when the engine speed is above the threshold value, gradually increasing the threshold value of the throttle opening from the specified lowest value, and controlling the throttle opening so that it may become the threshold value. CONSTITUTION: When that the engine speed E is higher than the threshold value Es is found, whether the vehicle speed S is approximately zero or not is judged from an output signal of a vehicle sensor 5. When that the partial high loading state where the vehicle is to be run up a step is generated is judged, whether the throttle opening R is beyond the threshold value H or not is judged from an output signal of a throttle opening sensor 6. As a result, the normal throttle driving mode is made when that R is less than H is found, and the throttle driving mode is made by limiting the throttle opening R to the threshold value H when that R is not less than H is found.

IPC: B22D31/00
Filed: 1988-01-25
Abstract: PURPOSE:To prevent the thermal conversion of a casting sand and to enable the reuse by performing the water spray of the drum inside of a cooling drum device according to the ratio of the sand weight of a sand mold to the casting weight of a casting. CONSTITUTION:The sand mold 4 with incorporating a casting 41 is inputted into a rotary drum 3 via the input port 32 of a cooling drum C. The casting incorporating sand mold 4 removes a mold sand 42 from the casting 41 with repeating ascent and descent along a rotating drum wall. The mold sand 42 retrains at the lower part of the rotary drum 3 and gets into contact with the casting 41. A spray nozzle 5 sprays water to the mold sand 42 via an injec tion port 51. At this time a valve device 6 adjusts the cooling water amt. accord ing to the ratio of the mold sand weight of the casting incorporating sand mold 4 to casing weight. Therefore, there is no incomplete cooling of the casting nor excess cooling. The casting sand is reusable because of no thermal conver sion of the casting sand and also it is easily separated from the casting because of its becoming no lumpy.

Title: Semiconductor storage device
Inventor: KUMANOTANI MASAKI
IPC: G11C11/401
Filed: 1987-01-23
Abstract: PURPOSE:To stabilize an operation by constituting the titled device so that among blocks selected at the time of a split operation, a sense amplifier of the block containing a selected data line is operated earliest, and a sense amplifier of other block is operated later. CONSTITUTION:All memory cell trains of a RAM are split by an address RA8 and a RA9 of the uppermost level. Sense amplifier driving signals phiS8, the inverse of phiS8 are decoded by the RA8 and the RA9. For instance, a sense amplifier activating signal phiS80 against a block (RA8, RA9)=(1,0) is outputted through a NOR2 immediately when the signal phiS8 is inputted to a NAND6, but in case of (1, 1) the phiS8 is inputted to a NAND5 and delayed by an inverter INV4, and thereafter, the phiS80 is generated through the NAND5 and the NOR2. In such a way, by delaying and quickening the sense amplifier activating signal, a peak current at the time of sensing decreases remarkably, and the operation of the device can be stabilized.
