Title: Ink dot printer
Inventor: OKUNO SHIGERU
IPC: B41J2/305
Filed: 1984-10-25
Abstract: PURPOSE:To shorten the return time of an armature by a repulsive force thus performing high-speed printing by fixing a needle to an armature integrally and regulating the position of a magnetic suction direction by the drive part of the armature using a stopper. CONSTITUTION:The base of an armature 23 opposed to a core 21 is mounted to a yoke 22 in a freely movable fashion, and the operating position of a direction where a suction by the core 21 of each armature 23 occurs is regulated by a collision with the core 21. A needle 24 is fixed at the tip of these armatures 23. If the coil 20 is energized according to a printing signal, the armature 23 is sucked by the core 21. However, the operation of the armature 23 in a suction direction stops by the collision of the armature 23 with the core 21. Since both are made of metal, the core 21 which operates as a stopper gives a repulsive force in a return direction to the armature 23.

Title: Smell detector
Inventor: KOMATSU TAKASHI
IPC: G01N27/04
Filed: 1988-09-09
Abstract: PURPOSE:To allow sure smell detection without being affected by a change in temp. and humidity and drift by differentiating the output signals of semiconductor gas sensors and outputting a detection signal when the derivative thereof attains a prescribed value or above. CONSTITUTION:The sensor outputs from the semiconductor gas sensors 1 which are provided in 8 sets and a preamplifier 2 are digitized by an A/D converter 4 respectively via an optical fiber 3 and are outputted to a microcomputer 5. The signals are smoothed in the computer 5. The smoothed signals are then differentiated and the change rate thereof is determined. The averaging per prescribed time is executed. The differentiated average value is displayed on a display means 6. On the other hand, the computer 5 makes decision as to whether the differentiated average value is above the prescribed value or not and outputs the detection signal if the value is above the prescribed value. An alarm is then emitted by an alarm device 7. The sensor outputs change sharply and the derivative increases if a burning smell or the like arises in this case. The smell detection is then executed but the output conversion is slow in case of the drift and, therefore, the derivative falls down to the prescribed value or below and the detection signal is not outputted. The sure detection is thus executed.

Title: Static ram
Inventor: MITSUMOTO KINYA
IPC: H01L27/10
Filed: 1991-08-10
Abstract: PURPOSE:To prevent a power-supply current at a low power-supply voltage from being increased by forming a control signal for forcing a word wire to be set to a non-selected level when a power-supply voltage is equal to or less than a specified voltage in terms of its absolute value by incorporating a voltage-detection circuit. CONSTITUTION:A high level such as a grounding potential of a circuit is outputted and is taken into a latch circuit corresponding to ON state of a p-channel type MOSFET Q1 at a low-voltage region. An output inverter circuit N4 of a latch circuit outputs a low-level control signal. Since a gate circuit G which constitutes a decoder circuit according to a low level of an output signal of a low-voltage detection circuit forms a high-level output signal regardless of an address signal which is level-converted, a word driver WD enables a word wire to be a low-level non-selection level, thus preventing a DC current from flowing through a load of a complimentary data wire and a memory cell.
