A programmable electronic calculator having a display register for storing numerical information is provided with an additional register which always contains the current instruction code and program statement number. A control on the keyboard permits the display of either register without disturbing the contents of either register.

A resetting apparatus for an electronic timepiece wherein a frequency divider circuit having a logic circuit incorporating complimentary MOST is provided with a control means for resetting said divider circuit which is also connected to the input amplifier of said divider circuit to cut said input amplifier off.

An electronic lock in which the key combination necessary for opening it is determined by an easily replaceable plug whose terminals have been jumpered or strapped in an arbitrary arrangement. The key for the lock is a second plug. When strapping in the second plug is identical to that in the first plug, insertion thereof permits the lock to be opened; if the strapping does not match, the lock cannot be opened. Options include initiation of an alarm if a key with incorrect strapping is inserted,...

A circuit for respectively flashing signal lamps. The circuit includes at least two cooperable transistors, charging circuit with a main capacitor, a secondary capacitor to ensure stable operation, a main relay, a secondary relay, and a direct current source. The circuit is designed to be insensitive to transistor current gain variations and to be immune to parasitic capacitances.

An electronic device such as a laser diode is mounted on a heatsink assembly within a TO-can package. The heatsink assembly is mounted in heat exchange relation with a heat pipe by being on or adjacent a heat pipe. The heat pipe is either attached to an exterior face of the TO-can package or passes into the TO-can package to efficiently draw heat away from the heatsink assembly.

An electronic ballast which includes a resonant load circuit (L1, C1) in series with a discharge lamp (LA), the resonant load circuit being supplied by an inverter (S1, S2) which outputs variable alternating voltages at frequencies above 200 KHZ. Alternatively, an electronic transformer incorporates a load circuit and a variable output frequency inverter for operating a low volt halogen lamp (7) at variable alternating frequencies above 200 KHZ. Passive components of the ballast and transformer ...

Performance of an electronic device is highly improved by epitaxially growing a perovskite-type oxide thin film on an inorganic amorphous layer or an organic solid layer in a desired direction; and furthermore, a high performance electronic device is provided by incorporating the electronic device into an integrated circuit, wherein oxide thin layers are formed on the inorganic amorphous layer or the organic solid layer, and the perovskite-type oxide thin film is grown epitaxially on the oxide l...

An EL display having high operating performance and reliability is provided. LDD regions 15a through 15d of a switching TFT 201 formed in a pixel are formed such that they do not overlap gate electrodes 19a and 19b to provide a structure which is primarily intended for the reduction of an off-current. An LDD region 22 of a current control TFT 202 is formed such that it partially overlaps a gate electrode 35 to provide a structure which is primarily intended for the prevention of hot carrier inje...

An electronic digital timer for an electronic range wherein the desired time of cooking is determined by a time setter; the time of cooking thus set is indicated in a digital fashion; a counter counts the number of pulses generated when the electronic range commences heating; and the heating operation is brought to an end when coincidence takes place between the number of counts made by the counter and a number determined corresponding to the preset time.

An electronic device includes: a main unit; a cap unit that is capable of having a portable electronic device attached thereto and is capable of tilting; a driving unit that causes the cap unit to tilt with respect to the main body; and a controlling unit that drives the driving unit so as to return the cap unit to a reference position, when detachment of the portable electronic device from the cap unit is detected.
