A device for control of driving a power window automatically holds a switch in its operated state to continuously raise or lower a door glass by continuously rotating a motor. The device stops the motor when a locking current flows through the motor upon complete closure or complete open of the door glass. The device includes a thermistor inserted in a signal line through which current flowing through the motor passes. The thermistor is disposed in the vicinity of the motor. When a locking current flows through the motor, the current also flows through the thermistor so that the thermistor is heated and shuts off the current flowing therethrough so as to stop the supply of electricity to the motor when the temperature of the thermistor exceeds a predetermined value. Also, the thermistor has a function of shutting off current flowing therethrough when receiving heat radiated from the motor due to over current.

A catheter that is guided into an intra-corporeal passageway is set forth. A catheter tube accommodates an element having a piston for detecting a pressure in the intra-corporeal passageway. Silicone gel is accommodated in the catheter tube to transmit the detected pressure in the catheter tube. A strain gage is disposed on a semiconductor chip to output an electric signal based on an amount of a deformation thereof indicative of the pressure in the catheter tube.

A power window driving control device formed of a measuring device which measures time elapsed since closing of a window glass has been designated by a switch, a sensor which detects a completely closed state of the window glass, a current detecting device which detects that current flowing to a motor when the window glass is being closed exceeds a predetermined value, and a driving control device which effects one of stopping the motor and stopping the motor after driving the motor reversely for a predetermined time, in at least one of a first state, in which the current detecting device detects that the current flowing to the motor exceeds the predetermined value and in which the completely closed state of the window glass is not detected by the sensor, and a second state, in which the time elapsed since closing of the window glass was designated exceeds a predetermined time. Even if a foreign object exists on a path of movement of the window glass in a closing direction, the foreign object is not caught between the window glass and a window frame so that stability is guaranteed.

An accelerometer sensor is disclosed, utilizing a casing having a center axis, and a pressure sensitive element located at the bottom portion of the casing. A gel based medium is accommodated in the casing. Given that 'x' denotes a positional deviation of the pressure sensitive element with respect to the center axis of the casing and that 'h' denotes a height of the medium in the casing, the positional deviation (x) and the height (h) are set such that the value 2 x/h falls within a predetermined range and serves as a function of the anisotropic sensitivity ratio of the sensor.

An object of this invention is to make it possible to directly monitor a temperature of a transistor chip. According to the present invention, p.sup.- region is formed on a substrate of a p.sup.+ layer by epitaxial growth. A first n-type diffusion layer which is a base region, and a second n-type diffusion layer which forms a temperature detecting element are formed in the p.sup.- region. A first p.sup.+ diffusion layer which is an emitter region is formed in the first n-type diffusion layer, while a second p.sup.+ diffusion layer which forms the temperature detecting element is formed in the second n-type diffusion layer. The temperature detecting element is operated in the active region, so that a characteristic free from variations in collector potential is obtained for the base-emitter potential difference of the temperature detecting element and the temperature of the junction thereof. Owing to this characteristic, the temperature of the junction can be detected from the base-emitter potential difference of the temperature detecting element during operation of the transistor.
