Title: Control device for internal combustion engine
Inventor: OKUBO SATORU
IPC: F02P5/15
Filed: 1987-09-29
Abstract: PURPOSE:To prevent abnormal increase of NOx concentration in exhaust gas, by a method wherein temperature in a cylinder when a pressure in a cylinder is maximized is determined, and feedback control is made on either in air-fuel ratio or an ignition timing so that the determined value is adjusted to a value lower than a given value. CONSTITUTION:A control device 15 performs feedback control of an air-fuel ratio based on detecting signals from an airflow meter 2, a water temperature sensor 6, and an exhaust gas sensor 9 through drive of a fuel injection valve 10 when a detecting value by an exhaust gas temperature sensor 17 is below a given value. In this case, detecting signals from a crank angle sensor 7 and a pressure-in-cylinder sensor 13 are inputted to the control device 15. The maximum value of a pressure in a cylinder within one ignition cycle and a crank angle at a point of time when a maximum value is generated are detected. Based on the maximum value and the crank angle, a temperature in a cylinder is calculated, and a control signal for fuel injection is outputted according to the temperature in a cylinder.

Title: Zn coated wire for arc welding
Inventor: MATSUYAMA TOSHIYA
IPC: B23K35/02
Filed: 1986-10-20
Abstract: PURPOSE:To improve the crack resistance and toughness of a weld metal by using a low-carbon wire for arc welding contg. specific weight % or below of C and coating Zn having prescribed % or above of purity by a specific thickness onto the surface thereof. CONSTITUTION:Zn having >=90% purity is coated to 0.5-20mum thickness by a method such as dipping on the surface of the low-carbon wire for arc welding contg. <=0.05wt% C to form the coated electrode. Vapor of metal Zn is generated to shield the weld zone and to prevent the infiltration of N2 from the external air to the deposited metal prior to the formation of the droplet at the wire end if arc welding is executed by using such wire. Since the increase of N2 into the weld metal is prevented, the toughness of the weld metal is improved and since the content of C in the wire is low, the crack resistance at a high and low temp. is improved as well.

Title: Outdoor unit of air conditioner
Inventor: KAZAOKA MOTOHIRO
IPC: F24F5/00
Filed: 1986-10-17
Abstract: PURPOSE:To recover heat from air which has cooled electrical equipment so as to enhance the overall heat exchanging efficiency by disposing the heat generating electrical equipment on one side of the electricals sections to oppose a ventilation port, and forming a cooling passage that leads from the ventilation port to the windward side of an outdoor heat exchanger. CONSTITUTION:By operating a blower fan 26 of an outdoor unit, air is drawn from the inlet of a main air passage through an outdoor heat exchanger 25 for heat exchange to be supplied out of an outlet 21. At an electricals section 27, outside air is taken in from a ventilation port 32 disposed on its side. The air passing through a cooling passage 33 contacts a reactor 30 and heat dissipation fins 31 of a giant transistor 29 to cool them, and the heated air flows to the side ahead of the outdoor heat exchanger 25. The total air passing through the cooling passage 33 passes through the outdoor heat exchanger 25, and, after its heat was recovered, is supplied out of the outlet 21. Since the outdoor heat exchanger 25 acts as evaporator when operating under heating mode for instance, the heat is recovered by causing the hot air heated when cooling heat generating electrical equipment in the cooling passage to flow through the outdoor heat exchanger 25.

Title: Throttle controller
Inventor: TERASAWA TEI
IPC: F02D11/10
Filed: 1989-09-25
Abstract: PURPOSE:To avoid unuseful connection/disconnection by connecting a drive means to a throttle opening/closing means for a predetermined period after the return by using a second control means according to a relative difference between an operation amount of an accelerator and a throttle opening in a rapid accelerator returning operation. CONSTITUTION:A drive control means M7 opens a throttle valve 11 when an operation amount of an accelerator operating mechanism M3 is smaller than a predetermined amount. When the throttle valve is opened larger than a preset angle, a first control means M11 controls a clutch means M6 to separate a throttle opening/closing means M1 from a drive means M4. A second control means 12 maintains the connection of the drive means M4 and the opening/ closing means M1 independently of the first control means for a predetermined period on the basis of a signal output from a relative difference detector M10 according to a relative difference between an operation amount of an accelerator and a throttle opening detected by detectors M8, M9 in case of a rapid accelerator returning operation. Therefore, unuseful connection/disconnection of the clutch means can be avoided, thereby realizing a stable throttle control.
