Title: Constant speed running control device for vehicle
Inventor: ISHIDA AKIRA
IPC: F02D29/02
Filed: 1991-09-18
Abstract: PURPOSE:To lessen drop in vehicle speed when set resuming is started, and thereby eliminate unreasonable control at a high step position of gear shifting when a vehicle is running on an up-hill road. CONSTITUTION:The actual vehicle speed of a car body 19 is detected by a vehicle speed detection sensor 12, the actual detected speed at the time of setting by a commanding means 11, is set by a target value setting means 13 as a target vehicle speed Vset and constant speed running is then started. In this case, the vehicle speed is controlled by adjusting an actuator 18 based on the controlled variable computed by a controlled variable operating means 15. A target track vehicle speed Vd(t) at the time of constant speed running and resuming is computed by a target track setting means 14. The value of control input characteristics is renewed by a control input factor deciding means 16 by the use of deviation between the target track vehicle speed Vd(t) and the actual vehicle speed, and the controlled variable to the actuator 18, and change timing for each step of gear shifting is determined by a speed change commanding means 17 by the use of control input characteristics and the deviation, so that switch-over to a step position of gear shifting in response to a running condition is thereby made.

Title: Heat exchanging ventilating device
Inventor: MATSUKI YOSHITAKA
IPC: F24F7/08
Filed: 1994-09-30
Abstract: PURPOSE: To unify the distribution of outlet air of a fan, whose air outlet port is arranged at the terminal side of a heat exchanging element in the laminating direction thereof, as much as possible. CONSTITUTION: A guide member 41 is provided in a casing 10. The guide member 41 guides air stream, discharged against the terminal side of laminating direction L of a heat exchanging element 30, so as to flow along the corresponding flow passages from the end surface side in the laminating direction L of the heat exchanging element 30. According to this method, the outlet air stream is diffused along the heat exchanging element 30 and is guided into the corresponding flow passages whereby the distribution of discharging air out of the heat exchanging element 30 can be unified as much as possible. Accordingly, there is a merit that the heat exchanging efficiency is also improved. On the other hand, it becomes unnecessary that the output of the fan is set so as to be big enough to compensate a pressure loss.  The restriction of noise can be contrived and the increase of electric power consumption can be restrained.

Abstract: PURPOSE:To prevent the deterioration in resolution even if an original deviates from the prescribed position by placing movable parts at plural different positions and deciding the number of changing times of a binarization signal, which can be obtained by reading the same line on the original. CONSTITUTION:An image sensor 4 obtains a read signal D1 with the movable part 52 floating by a distance l1 and a read signal D2 in parallel with a main body part 51. The read signals D1 and D2 are converted into binalization signals E1 and E2 by a comparator 12, stored in the 1st and 2nd RAMs 13 and 14, respectively, and inputted to an up-down counter 15. It counts up how many times the binarization signal E1 changes and counts down how many times the binarization signal E2 changes. If said result is positive, it means that the binarization signal E1 changes more often than the signal E2 and the original is better focused, and vice versa of if the result is negative.
