Title: Semiconductor pressure sensor
Inventor: HASHIMOTO HIROKAZU
IPC: G01L9/04
Filed: 1992-05-18
Abstract: PURPOSE:To reduce the size of the sensor without lowering the sensitivity of the sensor by using a silicon-on-insulator (SOI) substrate formed by joining a second silicon substrate to the surface of a first silicon substrate with a silicon oxide film in between as the semiconductor substrate of the sensor. CONSTITUTION:An SOI substrate 25 is formed by joining a second Si substrate 24 having a crystal orientation in its (110) face to the surface of a first Si substrate having a crystal orientation in its (100) face with an SiO2 film 23 in between. Then a thin diaphragm section 26 is formed by etching off the rear-side central part of the substrate 22 and a plurality of piezo-resistors 27 and 27 are formed on the surface 26a of the section 26 by impurity diffusion. When a pressure is applied to the section 26, the section 26 is displaced and the resistances of the resistors 27 and 27 change due to stresses generated in the resistors 27 and 27. By forming a bridge circuit of the resistors 27, 27,... and driving the bridge circuit with an electric current, a voltage output proportional to the magnitude of the pressure can be obtained.

IPC: F24F13/14
Filed: 1990-05-15
Abstract: PURPOSE:To prevent a low temperature draft from being generated around a part just below an air blowing port by a method wherein a limit switch for detecting both ends of reciprocation having a maximum flap angle of a movable flap is provided, and a motor performs an intermittent operation only at the beginning period ranging from a state of the maximum flap angle to other directions. CONSTITUTION:An intermittent operation of a motor 20 under a time control only of an initial or beginning period at each of half part of a going and a returning part of a reciprocating movement of a movable flap 2 is carried out, and during the remaining period, the motor 20 is continuously operated. The intermittent operation is already completed by the time ranging from a state in which a flap angle shows a maximum value (b) to another state of (a). In this way, with such an arrangement, normally, the flap angle and an air direction angle are varied in response to the reciprocating movement of the movable flap 2. In view of the fact that a dispersion of a power transmitting system ranging from the motor 20 to the movable flap is found, there is no occurrence of such a circumstance as one in which the movable flap 2 is stopped within a range of an air directing angle of 0 deg.-B.

Title: Tape take-up detector
Inventor: KONDOU SHIGEYUKI
IPC: G11B15/093
Filed: 1983-07-11
Abstract: PURPOSE:To detect the end of the tape take-up as soon as the last one turn is taken up by delivering a tape sag signal after comparing the output voltage of a tape tension detecting means with the reference volage. CONSTITUTION:When the quantity of remaining tape becomes small in a take-up mode, a tape end signal is delivered from a tape end detector 1. In this case, a tape T is still wound round both reels and a tension arm A is shifted to a position where the spring force is equal to the tape tension. No tape sag signal is delivered yet from a tape sag detector 2. The termination of the tape T becomes free at a moment when the last turn of the tape T is taken up. Thus the tape tension is set at about 0, and the force of a spring mechanism B overcomes the tape tension. Then the tension arm means A moves to the position where the tape tension is 0, and a potentiometer P delivers voltage. Then a tape sag signal is delivered. A tape take-up detecting circuit 3 delivers a tape take-up end signal.
