摘要:
The present invention provides an electromagnetic relay that has a long service life, even when being used for interrupting high voltage, and that can be miniaturized. In this electromagnetic relay, the circuit interruption is cut-off by two or more keying circuits, which are operated by a single coil and connected in series. Thus, an amount of generated arc per keying circuit is suppressed. Consequently, the service life of the electromagnetic relay is lengthened. Moreover, the space between the contracts thereof is reduced, so that the electromagnetic relay is miniaturized. Additionally, a magnetic field for extinguishing arc is formed by a back or counter electromotive force generated when the circuit is cut-off. Thus, the generated arc is extinguished.

A tape cassette having a case body including an upper case and a lower case, a recessed portion formed on the side of a lower surface of the case body, and a slider so provided in the case body as to be slidable for opening and closing the recessed portion, is disclosed. The tape cassette further has a lock member positioned at an opening of the lower case to lock the slider in respective positions where the recessed portion is closed and opened, and a biasing member, supported at its two side ends with the opening being interposed therebetween by an inner surface of the lower case, for biasing the slider to a lock position.

A cartridge including a housing which holds a tape medium or disk medium and which is composed of upper and lower casings. The two casings are joined with screws in bosses formed at their four corners. The cartridge is characterized in that the bosses in at least one of the upper and lower casings have ends with partially different heights each so that, when the upper and lower casings are joined, their bosses come in contact with one another before the sidewalls of the in casings are mated.

A method for manufacturing a semiconductor memory device, including the steps of: forming a plurality of stripes comprising a first floating gate material film and a ion implantation protective film, covering one longitudinal side wall of the stripes with a resist pattern; removing a given width of the other side wall of the first floating gate material film by an isotropic etching in use of the resist pattern as a mask; forming an impurity region of low concentration by implanting impurity ions of a second conductivity type into the semiconductor substrate of the first conductivity type in use of the ion implantation protective film as a mask in a tilted direction after removing the resist pattern; and forming asymmetrical impurity regions on both sides of the stripe like first floating gate material film as viewed in the cross section along the direction perpendicular to the longitudinal direction of the stripes. According to the above-mentioned method, without using a side wall spacer, a semiconductor memory device provided with asymmetrical impurity regions having precisely desired forms can be obtained.

Bar with count values indicating widths of white and black bars, which are reciprocally obtained, are input to buffers connected in series at 16 stages. The bar width count values written to those buffers are sequentially shifted each time a new bar width count value is input. A comparing circuit compares the widths of the adjacent bars in the same color with each other and checks whether or not a ratio therebetween falls within a range of 0.2-5.0 times as large as each other. Results of the comparisons by this comparing circuit are written to result registers connected in series at 13 stages. The check-results written to those result registers are sequentially shifted each time a new bar width count value is input. Accordingly, if all the check results written to all the result registers indicate an "in-range" state, it follows that the fifteen or more bars consecutively meet a bar code condition. Hence, the counter lets an AND gate open. If even one of the check results written to the result registers indicates an "out-of-range" state, the counter starts counting. Then, when a count result reaches 17, the counter lets the AND gate close. Therefore, just when one of the check results written to the result registers is in the "out-of-range" state, the bar width count value written to each buffer is output. The bar width count values input thereafter are disposed of.

A container for containing printing liquid for supplying to an ink jet head for an ink jet recording apparatus. The container includes first and second chambers, with the first chamber containing negative pressure producing material and having an air vent communicating with ambient air and a supply port for supplying printing liquid to the ink jet head. The second chamber communicates with the first chamber via a communication port and provides a printing liquid reservoir for the first chamber. In an area adjacent a wall extending from the communication port, a capillary force provided by the negative pressure producing material decreases in a direction perpendicular to and towards that wall at least adjacent a part of the communication port which is uppermost when the container is in use.

A laser beam generation control system of an optical mark reader device including a laser generating element, a laser generation control unit, a laser scanner unit for scanning a mark, such as a bar code or the like, and a signal processor unit for photoconverting a reflected light to read thereof; wherein the laser beam generation control unit turns ON/OFF the laser generation element by a predetermined duty to carry out a generation of the laser intermittently. Further, when a reflected light from the mark is detected during an intermittent generation of the laser beam, the laser generation element is turned ON to generate a laser beam continuously; and when a reflected light from the mark is not detected for more than a predetermined first time period during a continuous generation of a laser beam, the system is switched from continuous generation to intermittent generation.
