IPC: F04D25/10
Filed: 1991-02-08
Abstract: PURPOSE:To send wind certainly to a person by calculating the position of a transmitter, and directing the head of a fan toward the transmitter using 21 motor for moving the center of face turning. CONSTITUTION:Judgement is made to know whether the direction of a transmitter 63 calculated from the output ratio of a receiver is identical to the current facing direction of the head 41 of a fan. Unless the center of face turning of the fan head 41 lies in the direction of the transmitter 63, another judgement is made to know whether the head 41 of the fan is facing right or left about the obtained direction of the transmitter 63; if to the right, for example, a motor for moving the center of face turning is put on to move the center of face turning to the left. This motion is repeated until the center of face turning lies in the obtained direction of the transmitter 63. Thereby the wind can be sent certainly toward the person concerned.

Title: Detecting device for tire pressure
Inventor: TAGUCHI TAKEYASU
IPC: B60C23/00
Filed: 1992-02-04
Abstract: PURPOSE:To improve the detecting accuracy of tire pressure by having detecting means to detect the state of the tire pressure and correcting means to correct a comparison standard between the signal of resonance frequency component and judged value according to the running speed of a vehicle. CONSTITUTION:Corrective action is executed for the upper limit value fH and lower limit value fL of unspring resonance frequency which are set up correspondingly to the allowable upper and lower limit values of tire pressure with regard to heat generation in a tire occurring during high speed running for a long time. Namely, since the tire generates heat to expand air in it for increasing air pressure in it though the quantity of air in the tire is the same, the air pressure corresponding to the actual quantity of air in the tire can not be detected. Thus, in steps 180-240, the upper limit value fH and lower limit value fL of the unspring resonance frequency are corrected to accurately detect the tire pressure without bad influence caused by the heat generation of the tire.

Filed: 1988-02-01
Abstract: PURPOSE:To hold liquid surfaces of high and low temperature tanks at a specified position, by linking an air layer portion of the high temperature tank to that of the low temperature tank with a U-shaped tube. CONSTITUTION:An opening-closing lid 9a is opened and a sample cage 10 is moved to a low temperature liquid tank 3 to be immersed while the opening thereof is closed with a temporary lid 10. Upon the end of cooling, the sample cage 10 is pulled up and moved to a high temperature liquid tank 6 to be immersed while the opening- closing lid 9b is closed. Upon the end of heating, the sample cage 10 is pulled up to be returned by the center thereof while the opening-closing liquid 9b is closed. By repeating this operation, a heat impact test is applied to the sample. As each cycle is repeated, Florinate FC-43 of the high temperature liquid tank 6 moves to the low temperature liquid tank 3 and the liquid level of the high temperature liquid tank 6 lowers while that of the low temperature liquid tank 3 rises. When the liquid level of the low temperature liquid tank 3 reaches a connection port of a U-shaped tube 16, a solution of the low temperature liquid tank is returned to the high temperature liquid tank 6 passing through the U-shaped tube. As the solution remains on the bottom within the U-shaped tube 16, the entry of the air is cut off to prevent a heat loss regardless of any difference in the pressure generated between the low and high temperature liquid tanks.
