The transmission of the detecting information is displayed at a part 32 of a display part 31, and the display is confirmed in a room distant from the toilet 1. If the door 7 is not locked by mistake despite the presence of a person in the toilet 1, a human body sensor 15 set at the back side of a toilet seat occupied by a person detects the unlocked state of the door 7. This detecting information is transmitted and displayed at the part 32. Thus the useless going/returning frequency can be omitted to the toilet.

Title: Phase modulator for optical fiber
Inventor: IZUMI SEIICHI
IPC: G01C19/72
Filed: 1987-05-07
Abstract: PURPOSE:To always execute a stable phase modulation by applying a bias voltage being different from that of the time of winding of an optical fiber, to a piezoelectric element and applying a prescribed tension to the optical fiber, and also, superposing a desired modulated wave to the bias voltage and supplying it to the piezoelectric element. CONSTITUTION:A value of each element is set, for instance, to a numerical value as shown in the figure, and when a voltage of 100V is applied to a power source terminal 5, a modulated wave which is amplified to 30VP-P is fetched in terminal 11. On the other hand, to a bias terminal 12, a bias voltage of -300V is applied by which a voltage which has superposed a modulated wave to a negative bias voltage is applied to one electrode of a piezoelectric element 48. In such a case, when driving is executed so that the diameter of the piezoelectric element 48 becomes large by a negative voltage, an arbitrary tension is applied to an optical fiber 44. In such a way, by adjusting the bias voltage, a prescribed tension is applied to the optical fiber 44, and a stable phase modulation can be executed.

Title: Turbine nozzle for vacuum cleaner
Inventor: KITAMURA SHUSUKE
IPC: A47L9/04
Filed: 1988-05-06
Abstract: PURPOSE:To reduce the noise of a turbine wheel even when the flow velocity of a suction airflow passing a route is increased by causing the turbine wheel to have a blade train to be rotatingly-energized in receiving the suction airflow and the blade train formed so as to suppress the rotation. CONSTITUTION:Since a dust is not accumulated in a vacuum cleaner main body after the dust is rejected, the suction airflow to pass a subroute 22 and to flow into a turbine casing 8 collides with a proceeding wing train 23 at a very high speed, and thereby, a turbine wheel 4 starts to be rotated at the very high speed. On the other hand, due to the rotation, a retreating wing train 25 receives an air resistance in the turbine casing 8, it suppresses the rotation of the turbine wheel 4, the over-rotation of the turbine wheel 4 is prevented, and the rotation is stabilized. When the suction airflow is made more high-speed, the rotation suppressing effect of the retreating wing train 25 is simultaneously increased, consequently, the rotating speed of the turbine wheel 4 is made approximately fixed, and a very high-speed rotation condition is not generated. As a result, the noise due to a high frequency sound generated when the blade of the proceeding wing train 23 interruptively cuts the suction airflow and an oscillation generated due to the rotation of the turbine wheel 4 can be reduced.
