Patent JP-S63223444-A (JP)
Title: Ventilator
Inventor: NISHIO MINORU
IPC: F24F7/007
Filed: 1987-03-12
Abstract: PURPOSE:To enable the amount of the blowing open air to be suppressed to a specified value or less, by providing a brake device which generates a resistance force at the specified number of revolutions or more of an exhaust fan. CONSTITUTION:A title ventilator includes an exhaust fan 4, being capable of reversing, and a brake device 6. The brake device 6 consists of a generator 11 and a resistor 12 for radiation. The generator 11 comprises a permanent magnet 13, coupled to a rotary shaft 9 of a motor 5, and a coil 14 supported to a support frame 10. When, during non-running of the exhaust fan 4, the exhaust fan 4 is started to reverse by dint of the blowing open air, the permanent magnet 13 is actuated to generate an electromotive force at the coil 14. The force is converted into heat by means of the resistor 12 for radiation. When the number of reverse revolutions is increased, the electromotive force of the coil 14 is also increased and power consumption by the resistor 12 for radiation is also increased to suppress an increase in the number of reverse revolutions. This constitution forces the amount of the blowing open air to be suppressed to a specified value or less.

Abstract: PURPOSE: To simplify the total constitution of circuit, by operating a control of the bleed quantity in the method of a device controlled by an operation of two diaphragms, in cases where the feed-back of signal of an exhaust gas sensor of the engine is made to an air bleed of the carburetor.  
     CONSTITUTION: A main and low speed air bleed path 205, 206 of the carburetor 200 are linked to a device 500 having in its interior two sheets of diaphragms and its driven slit valves, with a suitable linkage operated to air induction path 210. A controller 310, that receives the signal from a sensor 103 installed in an exhaust pipe 102, controls a three-way solenoid valve 700 located on negative pressure tubes 214, 215, with the negative pressure, inducted through a negative pressure regulator 800, linked to and shut out from the atmosphere. And said negative pressure, being inducted directly to one of the diapharagms indirectly to another through a throttling 601 and a tank 600, makes the operational timing different between the both diapharagms.

IPC: F01M11/02
Filed: 1991-02-28
Abstract: PURPOSE:To reduce a braking load of a crank chamber and prevent exhaust gas from changing into white smoke by using the crank chamber in a two-cycle engine as an oil pump. CONSTITUTION:A supercharger 13 is provided in an air suction port 2. Scavenging and supercharging in a cylinder 1 are carried out by this supercharger 13. An oil outlet nozzle 17 and an oil injection nozzle 19 are provided in a crank chamber 4.

Consequently, pressure inside of the crank chamber 4 comes to be roughly constant, and work of pressure change inside the crank chamber 4 on an engine as a braking force (a braking load) is reduced. And, as oil does not enter the inside of the cylinder, exhaust gas is not whitened.

IPC: H04L7/00
Filed: 1990-03-12
Abstract: PURPOSE:To preclude the fear of writing an erroneous data by providing a clock generating means generating a clock to each unit. CONSTITUTION:Each of units 1, 2,..., N is provided respectively with clock supply sources 1H, 2H,..., NH and when a data is sent from the unit 1 to the unit N, the sender side unit 1 sends a reception timing pulse signal Nf-R to a reception memory MB-R of the unit . together with a data 1e. The unit N receives the transmission data, and control circuit NA uses a received clock signal 1a as a reception timing pulse signal Nf-R on the other hand, the reception timing pulse signal Nf-R sets the reception memory NB-R to store the data. Thus, normal data transmission is attained regardless of a transmission delay between units and the fear of write of an erroneous data is precluded.

Abstract: PROBLEM TO BE SOLVED: To prevent incorrect detection of a state caught by window glass, resulting from a temporary variation of pulse period caused by vibration, impulses, or the like, in a detection system of foreign materials by means of variation of pulse period. SOLUTION: A controller 2 inputs a pulse signal SP of a pulse period corresponding to the revolutional speed of a motor M to detect a foreign material caught by window glass on the basis of variation of the pulse period at respective detection times.

The controller corrects the difference of period at the time, when the difference is larger than an upper limit to discriminate whether the pulse period of the pulse signal SP obtained on the basis of the threshold is a temporary variation period or not.
