Abstract: It is an object of the invention to provide a vehicle alarm signal generation device which can realize the reduction of the consumption of power without unstabilizing the intruder detect operation. The vehicle alarm signal generation device includes a supersonic sensor which comprises a supersonic transmitter and a supersonic receiver. The supersonic transmitter radiates supersonic waves in the interior of a vehicle and the radiated supersonic waves are received by the supersonic receiver. If any person intrudes on the vehicle interior, then there is produced a difference between the frequencies of the radiated and received supersonic waves due to the Doppler effect generated responsive to the movements of the intruder, so that a beat frequency signal corresponding to the frequency difference is included in a signal received by the supersonic receiver. The beat frequency signal is integrated by an integrating circuit and is then converted into a voltage signal.

Abstract: An object of this invention is to provide a door unlocking device adapted unlock a door by transmitting a signal in the air through a signal transmitter, which can unlock the door even when the power source of the signal transmitter, namely, the battery has consumed up. With a door unlocking device, upon insertion of an ignition key into the rotor of a key cylinder, a shutter is opened to operate a shutter switch. Under this condition, the rotor is turned in opposite directions from the neutral position according to a predetermined rotor turning pattern. The rotor turning pattern is discriminated by a rotor-turning-pattern discriminating circuit. Ensuring that the rotor turning pattern is the one predetermined for unlocking the door, the rotor-turning-pattern discriminating circuit activates an electric operating mechanism to cause a lock mechanism to unlock the door.

Abstract: An object of this invention is to provide a key cylinder device which is simple in structure and is able to positively detect the presence or absence of the key. In a key cylinder device, a key cylinder body incorporates a rotor having a key inserting inlet, and a shutter made of a magnetic material is swingably mounted in the rotor to open and close the key inserting inlet, the shutter being urged by a spring to close the key inserting inlet. When the shutter is held closed, the magnetic force of a permanent magnet acts on a normally closed lead switch to hold the switch open. When the shutter is swung open by the key being inserted into the key inserting inlet, it covers the permanent magnet, thus interrupting the action of the magnetic force of the permanent magnet on the lead switch. As a result, the reed switch closes.

Abstract: An apparatus for controlling a power window capable of maintaining an energized state of the motor to move a window glass, detecting a locked-rotor current flowing through the motor when the window glass reaches a limit position, and de-energizing the motor to stop the movement of the window glass when the locked-rotor current becomes larger than a predetermined value. The period of time for energization of the motor is longer than a period of time from a moment at which the "ON" operation of the automatic mode switch is cancelled to a moment at which the window glass reaches the limit position. It is thereby possible to automatically de-energize the motor when the window glass reaches the limit position, even if the locked-rotor current does not become larger than the predetermined value at this time due to the influence of temperatures or other causes.

Abstract: A control apparatus suitable for use in a power window regulator is provided which has an electric motor for selectively moving a window glass in either one of two directions in which the window glass is fully closed and opened when an automode switch is first turned on. An energized state of the motor is held until the window glass reaches a position where it is fully closed or opened.

Abstract: Two leaf springs of substantially identical width which define first and second movable members are superposed on each other at one end and connected together. A movable contact is attached to the thus connected portion. The first movable member has a slot formed in a middle portion thereof. The width of an end portion of the second movable member is set so that the end portion can be inserted in the slot. A supporting member being inserted in the slot has a portion for swingably supporting an edge portion of the slot and another portion for swingably supporting an end portion of the second movable member opposite to the movable contact. The second movable member is curved so that upon application of a operating force to the first movable member the urging direction of the second movable member changes to cause a snap action to thereby selectively bring the movable contact into contact with one of the two fixed contacts.

Abstract: A switch device suitable for application in a window regulator of an automobile. The switch device is capable of detecting three distinct operations of a knob, and is comprised of: a first operation to one side from a neutral position; a second operation to the opposite side; and a third operation to the first side larger than the first operation. Two switches are provided in correspondence to the respective first and second operations and these switches are provided with contacts which are switched by these three operations. When the third operation is effected, an interlock member transmits this third operation to the second switch, whereby the contacts of both the first and second switches are caused to be switched simultaneously.

Abstract: An apparatus for controlling a window regulator connecting semiconductor switching elements which are turned ON or OFF depending on the ON-OFF state of operation switches and relay coils which are energized or de-energized depending on the ON-OFF stage of semiconductor switching elements connected to a power source through the operation switches. When the operation switches are OFF, a voltage is never applied to the semiconductor switching elements and therefore there is no fear of malfunction of semiconductor switching elements due to noise.

Abstract: A switch device for making a motor or the like alternate between forward reverse rotation, having a pair of switches and a control circuit. When either one of the switches is activated, the control circuit activates the motor in one or the other direction depending upon which switch is activated. When both switches are activated, the control circuit activates the motor until a desired action or task is completed. Therefore, when the present invention is used in a window glass lifting apparatus of an automobile, three kinds of operations of the window glass can be performed by using a pair of switches: partial upward and partial downward movement and continuous movement down to the fully open state of the window glass.

Abstract: A switching device of the type in which a moving contact provided at the free end of a movable component formed of a plate spring is brought into contact with and separated from fixed contacts by depressing the movable component by means of an operating member. The movable component is equipped with first and second movable parts which are arranged face to face and which are connected to each other at their respective free ends. A first support portion supporting the first movable part which is depressed by the operating member, is positioned farther from the free end than a second support portion supporting the second movable part. The first movable part is equipped with a curved section which allows it to remain free of the second support portion when it is depressed by the operating member.

Abstract: A photo-coupler with delay function includes a fluorescent substance, a light-emitting diode disposed at one end of the fluorescent substance and a phototransistor disposed at the other end of the fluorescent substance. While a light emitted from the light-emitting diode is impinging on the fluorescent substance, it emits a fluorescence. The fluorescent substance emits a phosphorescence after an emission from the light-emitting diode is interrupted. In this arrangement, when the fluorescent substance is displaced with an operating plate, the light intermittently emitted from the light-emitting diode impinges on the fluorescent substance. The phototransistor selectively detects the light intermittently emitted from the light-emitting diode, the fluorescence and the phosphorescence both continuously emitted from the fluorescent substance.
