Title: Fan capable of drawing and discharging air simultaneously at one side
Inventor: OGAWA HIRONARI
IPC: F04D25/16
Filed: 1981-03-23
Abstract: PURPOSE:To provide a fan capable of ventilating air completely, by causing suction and discharge of air forcibly, enabling to adjust the flow rates of suction air and discharge air by changing the blade angle of the fan, and preventing mixing of suction air and discharged air by imparting directivity to air flow by means of a fan guide. CONSTITUTION:Blades 4, 5 are fixed perpendicularly to a turning shaft 3 in the manner that air flows are produced in the opposite directions by the blades 4, 5 and drawing and discharging of air are caused simultaneously at one side of a fan by turning the shaft 3. Here, if such a fan is installed in a completely enclosed, empty room, any problem is not aroused since the amount of suction air is equal to that of discharge air. However, in case that gas is used in the enclosed room, flow rates of suction air and discharge air are adjusted by changing the angle of blades 4, 5 in the manner of keeping balance between the amount of air necessary for combustion of gas and that of CO2 produced by the combustion of gas. Further, since drawing and discharging of air is caused simultaneously and forcibly, air can be ventilated perfectly even in a completely enclosed box.

Abstract: PURPOSE:To attain the output of picture information despite a different output control system of a connected information output device by outputting the code data that is converted in accordance with the output control system. CONSTITUTION:An application 101 is started and a data file is produced. Then a data file for picture/text data produced by a driver and stored in a driver storing part 104 is converted into a control system of a printer 113. This converted data file is transmitted via a BIOS 105 and a communication part 106. Then a control part 111 of the printer 113 produces a bit image of the picture to be outputted from the data file for picture/text data received via a communication part 110 based on the calculated result of an arithmetic circuit of the part 111 or a font 107. The produced bit image is sent to a picture memory 108. The part 111 sends the bit image data to a printer engine 112 from the memory 108. Thus the picture information can be outputted in accordance with the output control system.

Abstract: PURPOSE:To display displacement by using a rectangular wave voltage directly and to adjust a measurement base point in a detection part by varying a measurement rectangular wave voltage so that the feedback voltage induced between a measuring core electrode and a reference core electrode become zero. CONSTITUTION:A measuring ring electrode 9, a correcting ring electrode 10, and a reference ring electrode 11 are applied with a reference rectangular wave voltage E1, a correcting rectangular wave voltage E2, and the measuring rectangular wave voltage E3 respectively.

Filed: 1992-01-31
Abstract: PURPOSE:To make an accurate control of a nozzle pressure and to accurately control the stable nozzle back pressure against the response lag of a sensor by detecting the nozzle back pressure with a sensor located just before the nozzle and providing a compensator. CONSTITUTION:A nozzle back pressure sensor 6 placed just before a nozzle 4 detect the nozzle back pressure accurately, resulting in preventing the influence due to the pressure loss in a conduit line 3. Further a compensator 7 integrates the deviation signal between a back pressure feedback signal BS and a set pressure value signal OS, adjusting the noise back pressure by means of a control signal Cs. As a result, the time deviation becomes zero in steady state, further the response lag of the sensor 6 prevent the pressure control system from being unstable, performing the stable nozzle back pressure. In short, the circuit 7 generates and compensates a control signal CS based on the pressure information and the set pressure information of the fluid under control detected by the sensor 6 is supplied to a pressure adjustment valve 1, resulting in stabilizing the nozzle back pressure control.

IPC: B60T8/1755
Filed: 1990-02-23
Abstract: PURPOSE:To secure the stability of a vehicle while obtaining a proper turning ability by providing a turning condition detecting means for detecting the turning condition of the vehicle, a road surface friction detecting means for detecting the road surface friction, and a wheel braking force setting means. CONSTITUTION:When a vehicle is turning, a wheel braking force setting means sets wheel braking forces to be different between the inner side and outer side in the turning direction to generate a yaw moment to assist the turning in response to the turning condition corresponding to signals from a turning condition detecting means and a road surface friction detecting means for detecting the turning condition of the vehicle and the road surface friction respectively, and the differential braking force is changed corresponding to the road surface friction. The differential braking force is thus decided considering the road surface friction also, so a proper control considering the road surface friction can be performed, thereby the stability of the vehicle can be secured because the turning ability does not become excessive even for turning on a low friction road.

Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To remove only a disturbance wave effectively, by removing a low- voltage disturbance wave when the application of disturbance wave continues over a given time according to the power level of the entered disturbance wave. SOLUTION: In a communication protective unit 20, a low-voltage disturbance wave removing unit 28 includes a current limiting element 8 connected in series between a telephone line 10 and a terminal device 2. An overcurrent of the disturbance wave invaded in the telephone line 10 is limited by the current limiting element 8. At the same time a high voltage disturbance wave removing unit 9 is provided to discharge the current into a ground terminal GND when the disturbance wave is over a given voltage level. When the voltage of the disturbance wave entered in the input/output terminal is below a driving voltage necessary for the disturbance wave removing unit 9, the resistance increases in the current limiting element 8 as the temperature increases gradually by the overcurrent carried in the current limiting element 8.  Then, the voltage applied to the current limiting element 8 is increased, and when the power is above a given level, a thermal contact 30 is closed and grounded to a ground terminal GND. As a result, the low-voltage disturbance wave is removed surely.
