Abstract: PURPOSE:To detect only frost by detecting output fluctuation from a coil for elastic wave detection based upon characteristic mechanical convergence operation which is caused cyclically when frost is brought into contact with an elastic wave propagation body. CONSTITUTION:A frosting detector which is constituted by providing a coil 8 for elastic wave excitation to one end side of the elastic wave propagation body 3 and an elastic wave detection coil 8 to the other end side detects the output of the coil 9 for elastic wave detection by a detecting means 21 and recognizes the representative value of the detected output by a 1st recognizing means 22. The recognized representative value of the output is compared by a 1st comparing means 24 with a set value. Further, a 2nd recognizing means 24 recognizes the fluctuation width of the output detected by a detecting means 21 and a 2nd comparing means 25 compares the recognized output fluctuation width with set variation width. Then an output control means 26 outputs a defrosting signal according to the output results of the 1st and 2nd comparing means 23 and 25.

IPC: D06M13/298
Filed: 1993-03-16
Abstract: PURPOSE:To improve stainproof properties and flameproof properties without decreasing adhesive force of a surface decorative cloth to a panel in a surface decorative panel prepd. by pasting the outer face of the panel main body with a surface decorative cloth.

Filed: 1983-03-31
Abstract: PURPOSE:To prevent a ribbon from being inappropriately fed, by a method wherein a ribbon guide is provided as close as possible to a thermal head, and it can be appropriately spaced from the head. CONSTITUTION:Ribbon guide rollers 36, 36a and auxiliary rollers 36b, 36c are fitted through fixed shafts 95 to movable arms 94, 94 which can be moved horizontallly in transverse direction on the top surface of a carriage block 76 with pivotally fitting members 93 (such as small screws) as respective centers. The fixed shafts 95 are erected at predetermined positions of the movable arms 94, and each thereof is provided at its upper end with a groove 97 into which a ring member 96 can be fitted. Paper guides 98, 98a fitted to the arms 94 prevent a paper 19 set on a platen 16 from making contact with a side part of the thermal head 26 at the time of reciprocating motion of the carriage E. Ribbon guides are provided as close as possible to the head 26, whereby the thermal printing ribbon led from a ribbon cassette toward the head 26 on the carriage E can be so guided that the ribbon span between the ribbon guide on the leading end side and the head 26 can be set to be very short. Accordingly, sagging of the ribbon existing at such part can be remarkably prevented from occurring.

Title: Excessive input protecting device for power amplifier
Inventor: KANAI YOSHIAKI
IPC: H03F1/52
Filed: 1988-03-09
Abstract: PURPOSE:To surely protect a power amplifier from excessive input by providing a comparator circuit which is operated for excessive input, a first inverting circuit which inverts the output of a photo interrupter, and a second inverting circuit which takes the output of the comparator circuit as the DC power source and operating a switching circuit with the output of the second inverting circuit. CONSTITUTION:At the time of excessive input, a comparator circuit 1 is operated and its output voltage goes to the high level. The output from a photo interrupter 2 is inputted to buffer circuits 6 and 7. Resistances R3 and R4 are set to the same value to output a waveform, which has the same amplitude as the input and has the opposite polarity, to the output of the first inverting circuit 3. Consequently, since the output of a buffer circuit 6 and that of the first inverting circuit 3 are waveforms whose amplitudes are equal to each other and polarities are opposite to each other, both outputs are canceled and the inverted input of a second inverting circuit 4 goes to the low level. Thus, the excessive input from an input 9 is dropped to the earth on the input side of a power amplifier 8 and is not inputted to the power amplifier 8.
