Title: Idle revolution number feedback controller of internal-combustion engine
Inventor: HASEGAWA SHIYUNPEI
IPC: F02D43/00
Filed: 1982-01-13
Abstract: PURPOSE:To reduce the operational frequency of an air amount control valve so as to  improve its durability by synchronizing a valve control means with a specific position  signal from a turned position detecting means to open the air amount control valve for a certain period, thereby ensuring the resonable supply of the air amount. CONSTITUTION:An electronic control unit (ECU)9 identifies the engine condition and  engine loaded condition. According to those identified conditions, the unit computes the  amount of fuel supplied for the engine 1, that is, an open period of a fuel injection  valve 10, and the amount of supplementary air, that is, an open period of the control  valve 6 and a lag time of the valve opening from the point at which a TDC signal of  the control valve 6 is generated. Based on the computed values, the unit supplies driving pulses which trigger the fuel injection valve 10 and the control valve 6. After the  lag time of the valve opening corresponding to the computed value passes from the  generation point of the TDC signal, the control valve 6 is opened for a period corresponding to the computed value to open an air passage 8, whereby the certain  amount of air corresponding to the valve open period is supplied for the engine via the  air passage 8 or so.

Title: Device to diffuse distribution by blowing-out
Inventor: ITO NORIHISA
IPC: F24F13/15
Filed: 1987-01-12
Abstract: PURPOSE:To diffuse a distribution by blowing-out uniformly by providing a piezo-electric vibrating body which vibrates with the change in applied voltage at an open port section for discharging gas, liquid, powder, sound waves, or light beams. CONSTITUTION:When a device to diffuse a distribution by blowing-out is applied to the blowing-out port 1 of a ventilator used for vehicles, a voltage which changes periodically, for instance that in an AC current at 150V, and 60 Hz. is applied to the piezo-electric bimorph 7 of a piezo-electric vibrator 6. Because the upstream side of the piezo-electric bimorph 7 is supported by a ventilator grill 2 through a stay 5, its downstream side end vibrates in the up-and-down directions 60 times per second. This vibration is transmitted to a vibrating plate 9 through an attachment 8. The vibrating plate 9 has elasticity, and because it is installed with an inclination of 45 deg. with respect to the face of the piezo-electric bimorph 7, the direction of the vibration amplitude changes 45 deg., so that two vibrating plates 9 of the piezo-electric vibrating body vibrate with 90 deg. phase difference. When the air is discharged from the blowing-out port 1 of the ventilator, the air stream which passes between the vibrating plates 9 changes the direction of its blowing-out 120 times per second in the up-and-down directions and right and left directions, so that the air is diffused and attains a distribution of wind velocity which is close to uniformity.

Title: Method for connecting terminal to printed board
Inventor: KITAGAWA TOSHIMASA
IPC: H01L23/50
Filed: 1993-01-14
Abstract: PURPOSE:To connect a terminal by small ultrasonic vibrating energy or small pressure. CONSTITUTION:The tip of a terminal 3 is adhered to the surface of the conductive circuit 2 of a printed board 1, ultrasonic vibration is applied while applying pressure to the conductive circuit 2 and the terminal 3 is connected to the conductive circuit 2 by metal diffusion. At this time, the terminal 3 provided with a recessed part 4 on the surface close to the base in the vicinity of the connecting part 3a is used. The ultrasonic vibration applied to the terminal 3 is attenuated by the recessed part 4 and is prevented from transmitting to the base from the connecting part 3a of the terminal 3. Thus, the consumption of the ultrasonic vibrating energy at the parts other than the connecting part 3a is reduced.
