Inventor: EGAWA YUKIO
IPC: F01P7/04
Filed: 1984-10-23
Abstract: PURPOSE:To prevent noise of a cooling fan for a vehicle engine from abruptly increasing, by determining a voltage applied to a fan motor in accordance with the temperature of the outside air, the temperature of cooling water, the speed of a vehicle, the rotational speed of an engine, the temperature of exhaust gas, the opening degree of a throttle valve. CONSTITUTION:A computing device 4 receives signals from an outside temperature sensor 1, a vehicle speed sensor 2, a cooling water temperature sensor 3, an engine rotational speed sensor 18, an exhaust gas temperature sensor 19 and a throttle valve opening degree sensor 20, and determines a voltage V to be applied to a fan motor 6, which is delivered to a motor control device 5. Further, when the thus determined voltage V exceeds about 1 voltage, the motor 6 is rotated at a fan rotational speed in accordance with the voltage V. Meanwhile, when the voltage V is less than about 1 voltage, or when it is less than about -0.5 voltage, the fan 7 is stopped, but when it exceeds -0.5 voltage the condition until then is sustained. With this arrangement it is possible to prevent the rotational speed from increasing and to restrain noise.

IPC: F23J11/00
Filed: 1992-08-24
Abstract: PURPOSE:To evenly distribute the exhaust gas which, relating to an incinerator with a boiler as an adjunct thereto, flows through a set of heat-transfer tubes of the boiler set in the flue for the exhaust gas from the incinerator. CONSTITUTION:In an incinerator in whose flue 17 for the exhaust gas 25 a set of heat-transfer tubes 18 for a boiler as an adjunct to the incinerator are set, there is provided an exhaust gas flow-directing means 31 at a bent part 16 in the flue 17 formed upstream from the heat-transfer tubes 18. This exhaust gas flow-directing means 31 distributes the exhaust gas 25 appropriately at the inlet to the flue 17 and prevents the exhaust gas 25 from flowing back at a region on the side of a partition wall 23 in the flue 17. As a result, the flow-rate of the exhaust gas 25 is leveled out at the inlet to the set of heat- transfer tubes 18 and the tube surfaces in the set 18 are kept from being locally heated to an especially high temperature. Therefore, high-temperature corrosion damaging the heat-transfer tubes 18 can be prevented.

Title: Semiconductor device
Inventor: MIHASHI JUNICHI
IPC: H01L21/3205
Filed: 1986-09-20
Abstract: PURPOSE:To contrive improvement both in moisture proof property against infiltration of moisture and the life of the title semiconductor device by a method wherein the overlapped region of the protective film and an aluminum wiring on the end part of a bonding aperture is formed to be wider in the direction of introduction into the internal part of the device of the aluminum wiring than in the other direction. CONSTITUTION:The aluminum located under a protective film is corroded by the moisture infiltrated from the corners and the like of a bonding aperture part 4. However, as the overlapped region 51a at the end of the bonding aperture region on the lead-out side an aluminum wiring 3 is formed sufficiently wider than the other regions 52-54, it takes a sufficiently long period of time on the region 51a before the aluminum is corroded due to the infiltration of moisture. Consequently, as the tolerance to the corrosion of aluminum in a bonding pad structure can be sufficiently large, a resin-sealed semiconductor device having high degree of moisture proof property can be obtained.

IPC: H01L31/10
Filed: 1993-09-08
Abstract: PURPOSE:To provide an optical waveguide type photodiode, whose delay in response speed of output electric signals and distortion of output signal waveforms are suppressed by maintaining uniform distribution of generated carrier density and preventing distortion of the distribution of electric field strength. CONSTITUTION:An n type InGaAsP optical waveguide layer 7, an n type InP layer 5 and an i type InGaAs optical absorbing layer 4a are interlaid in order and formed in stripe on the center of the surface of the n type InP substrate 5, and a semi-insulating In P layer 3 is formed on both sides of these layers. Since this enables to prevent optical absorption from occurring only in the vinicity of one end when light directly enters the optical absorbing layer, this can prevent the distribution of electric field strength from distorting at the optical absorbing layer, thus suppressing a delay in response speed of output electric signals and distortion in output electric signal waveforms due to distortion of the distribution of electric field strength.
