Abstract: A zero-power wide OR gate (500) for implementing the "sum" of the "sum of product terms" in a programmable logic device (PLD). The wide OR gate (500) includes a single additional input transistor (502) for each added "product term" input from a sense amplifier. The wide OR gate (500) further includes circuitry to decouple the current supply from sense amplifiers turned on during sleep mode to limit power utilized. To increase operation speed, the wide OR gate (500) utilizes a strong current source (504) when sense amplifiers are all turned off to quickly pull up internal circuitry while utilizing a weak current source (506) when sense amplifiers turn on to allow the sense amplifiers to more easily overcome the current supply. To further increase speed, the wide OR gate includes a threshold shifting transistor (514) to shift the pull down threshold of the output inverter (512) for when all sense amplifiers are turned off while shifting the threshold back for when a sense amplifier transitions to on.

Abstract: A preliminary ejection sensor (29) of an ink jet recording apparatus includes a vibration plate (296) adapted to vibrate on receipt of an ink droplet ejected from an ejection port (323c) on a recording head (32) in order to detect the vibration of the vibration plate (296) depending on variation of a gap between a core (292a) and the vibration plate, whereby it can be checked whether ink is ejected from the recording head or not. In addition, the preliminary ejection sensor can check the present ink ejecting state of the recording head. Thus, in contrast with a conventional sensing system wherein ink ejection is sensed by an optical sensor on one side surface of the recording head, the structure of the ink jet recording apparatus can be simplified. Additionally, in contrast with another conventional checking system wherein a temperature sensor is disposed on the recording head to indirectly check the present ink ejecting state of the recording head by monitoring the elevated temperature, the ink jet recording apparatus assures that a checking operation can quickly be achieved at a high accuracy. Consequently, the ink jet recording apparatus makes it possible to exactly detect whether or not ink is correctly ejected from ink ejection ports (323c) formed on the jet recording head (32).

Abstract: Between the substrates with electrodes (13,14) arranged to face each other, there is held a nematic liquid crystal layer having a molecular arrangement capable of obtaining two or more directions of the tilt direction when an electric field is applied. The electrode structure is formed by a region having the conductive sections (13a,14a) the width of which is 50 µm or less in the widest part and the non-conductive sections (13b,14b) the width of which is 50 µm or less in the widest part per pixel. Between the substrates arranged to face each other, the conductive sections and non-conductive sections are opposed to each other at least per pixel in a part of the region in the pixel, and given the width of the narrowest part of the non-conductive sections as S, and the distance between the electrodes of the substrates arranged to face each other as D, the relationship of D ≧ S/2 is satisfied. With this structure, it is possible to obtain a liquid crystal display device-having a high light scattering characteristic at a low driving voltage, and also, with a high gradation having a bright. contrast ratio. There is no inverted display even when a gradation display is executed, and a liquid crystal display device can be obtained with an extremely wide viewing angle. These characteristics can be sufficiently maintained in practice in a state of a voltage being applied.
