Abstract: A crosslinked and oriented polyethylene film superior in clarity as well as moistureproofness and having an improved stretchability is produced by a process for producing a crosslinked and oriented polyethylene film such that the degree of crosslinking inwardly decreases across the thickness of the film, comprising using a polyethylene having a density of at least 0.935 g/cm.sup.3, a melt index of 0.5 to 20 g/10 min and a high-load melt index to melt index ratio of 40 to 200.

Abstract: The present invention utilizes a dimmer switch for alternating the lighting direction of a vehicle headlamp, but does so utilizing control apparatus that ensures that only low beam-directed light is emitted by the headlamp when the headlamp is turned ON. The possiblity which might be presented if oncoming traffic is suddenly met with high beam-directed light when an automobile driver turns his headlamps ON is thereby averted.

Abstract: An imaginary limit position is determined on the basis of a position where an overload condition is detected, and such imaginary limit position is stored. Subsequent to the storage, an extent of movement is limited to that defined by the limit position. An operational mode which re-establishes a stored position is provided. In response to the detection of an overload condition, a motor is reversed to move the attitude back through a small stroke, whereupon the motor is deenergized. When a manual switch is turned on, the motor is driven over an incremental time interval and is then deenergized temporarily. After a given time interval, the motor is again driven. Where a pluarlity of motors are driven simultaneously, the timing of initiating to drive each motor is displaced relative to each other by a small time increment during which a transient current occurs upon initiating the drive.

Abstract: A lamp failure detecting device for automobile consists of a lamp circuit including a plurality of lamps connected in parallel, a current-detecting resistance connected to a power-supply source through the lamp circuit in series, a first voltage divider circuit including resistances to which a voltage divided by the current detecting resistance and the lamp circuit is applied a second voltage divider circuit including resistances to which a voltage supplied from the power-supply source is applied and a comparator circuit comparing the difference between the divided voltages in the voltage divider circuits to produce a a failure detection signal. Diodes are provided in the first and second voltage divider circuits respectively in the forward direction. Non-linearity of the current flowing through the lamps for the change of the power-supply voltage is corrected by the diodes.

Abstract: A rotational direction sensor for a body such as a steering shaft of an automobile, which is rotatable from a preferred neutral position in either the clockwise or the anticlockwise rotational direction. When an actuating assembly is rotated in the clockwise rotational direction by more than a predetermined amount from the neutral position, a first switch is actuated so as to conduct a first electric current, while a second switch is not actuated, and when the actuating assembly is then returned to the neutral position in the anticlockwise rotational direction, the second switch is actuated to conduct a second electric current. An opposite switch actuation sequence occurs for initial anticlockwise and then clockwise rotation of the actuating assembly. A control circuit generates a first electric signal when it receives the first and then the second electric current as a pair and a second electric signal when it receives the second and then the first electric current as a pair.

Abstract: The present invention relates to improvements in a switch for a direction indicator suitable for use in a motor car comprising: a bracket operationally associated with a control lever for a direction indicator and rotatable through a predetermined angle in dependence on a direction indicated; a rachet opposed to the main body of the bracket through a steering wheel, opposite end portions of which are constantly biased in a direction of being engaged with opposite end portions of the main body of the bracket, and rotatable through a predetermined angle in dependence on a direction indicator; and a cancel cam formed at the periphery thereof with projections capable of releasing a condition of engagement between the end portions of the main body of the bracket in response to the rotation of the steering wheel in a state of having a slight clearance in the direction of rotation and rotatable along with the steering wheel.

Abstract: In apparatus for generating an alarm sound especially for small watches, all functions of the alarm are controlled by integrated circuitry which detects the state of a common connection point between a manually operable switch and a reference switch which is opened and closed by the timekeeping mechanism. There is thus only one external terminal led out from the integrated circuit for the purpose of connecting to the output side of the reference switch and the manually operable switch. The reduction in the number of terminals permits a corresponding reduction in the number of pins required and a reduction in the size of the circuit. The integrated control circuit includes flip-flops, gate circuits, inverters and a five minute counter.

Abstract: An indicator device for vehicles such as an automobile car which can show locations in a predetermined priority sequence if there is something wrong with various functions of the car, and comprises a plurality of indicating elements superposed in layers, each having a light source, light reflecting spots to represent a character and checking means for checking the light source, sensors for detecting changes in the functions, and an electrical control circuit actuated by signals from the sensors for energizing the light sources.
