Abstract: A laminated ceramic capacitor (10) divided into a first laminate (11), a second laminate (12), a third laminate (13), and a fourth laminate (14). The first laminate (11) includes a ceramic layer (15) serving as a dielectric layer. The ceramic layer (15) is thicker than a ceramic layer (17) sandwiched between internal electrodes (16a) in the second laminate (12) or the fourth laminate (14), and thinner than 20 times the thickness of the ceramic layer (17). The third laminate (13) includes dielectric layers, which serve as the ceramic layers (17), and has a thickness of 5% of the total thickness of the second laminate (12) and the fourth laminate (14). Accordingly, the third laminate (13) achieves the function of absorbing an electrode-induced thickness differential. Also, by means of regulating the thickness of the first laminate (11), portions of via electrodes (18) that extend without being electrically connected to the internal electrodes (16b) can be shortened.

Abstract: A laser unit capable of suitably updating a correction coefficient for correcting a laser output command for a laser oscillator. Validation of input of an update activation signal for the correction coefficient (F1=1) or waiting is carried out by operation of a display, a keyboard or a switch or by inputting an external signal. Flag F2 indicating automatic running, flag F3 indicating laser beam output and flag F4 indicating a shutter condition are checked. The correction coefficient is set to “1” only when flags F2, F3 and F4 are all equal to zero. Further, a laser output reference command value is outputted and the correction coefficient is updated after a predetermined time. Otherwise, a message indicating a reason for prohibition of update of the correction coefficient is displayed on an indicator, flag F1 is set to zero and the process is terminated.

Abstract: A laser machining apparatus capable of effecting a feedback control of a laser output from an early stage of operation and detecting an abnormality of the laser output quickly and precisely. A laser output command issued from a laser output commanding section is subjected to a feedback control and inputted to a laser pumping power supply for a laser oscillator. An output of a laser power sensor is amplified by an amplifier and compared with an output of a measurement simulating section for estimating the measured value of the laser output. A difference of the measured value and the simulated value of the laser output is inputted to the feedback control section and also to an output abnormality detecting section. A measurement input estimating section calculates an average power which should be outputted in a normal condition of the laser machining based on data of the laser output command. A fist order delay system can be adopted as the measurement simulating section.

Abstract: A lure having a body molded from a material having a lower specific gravity than water, and legs formed to extend to right and left sides of the body at a middle or rear portion of the body, and the legs have an elastic portion extending outwardly from the body as a center to right and left opposing ends of the elastic portion and a pair of water receiving portions secured to the right and left ends of the elastic portion, respectively, having openings toward the lure proceeding direction. The elastic portion repeats bending and bending back motions by elastic force and water resistance exerted to the water receiving portions, as the lure is manipulated to proceed, thereby rendering the lure move with imitated motions as of a small creature as a bait for fish.
