IPC: H05K13/04
Filed: 1990-08-10
Abstract: PURPOSE:To alleviate a labor by judging as end of one lot of a component containing tape when the times of no component suctions of a nozzle reach predetermined times, sucking a component of the next lot to mount when there is no mounted component. CONSTITUTION:When a printed board 15 is placed on an X-Y table 14, a component supply unit 1 for containing a chip component 2 is disposed at a suction station by the movement of a placing base 6. Then, when a suction nozzle 5 is moved by the rotation of a turntable 8 to suck the component 2, a component detection photosensor 8 detects presence or absence of the suction. Then, when the times of no continuous component suctions are counted by a counter and the counted times reach predetermined times of n times or less, it is judged that one lot of the component 2 having the same characteristics as those of a tape 4 is finished. Further, if there is no mounted component of one set having the same characteristic on the board 15, it is so controlled that the nozzle 5 sucks the component 2 from next lot of the tape 4 to mount it on the board 15.

Title: Detector of tape quantity
Inventor: YAMATE SHIGEMITSU
IPC: G11B27/17
Filed: 1983-11-11
Abstract: PURPOSE:To detect tape quantity quickly and properly at the time of starting of a travel by measuring a rotational frequency of a supplying reel in order to detect a remaining amount of a tape in a VTR. CONSTITUTION:A rotational pulse from a photosensor 6 is added to a waveform shaping circuit 21, and a shaped waveform is inputted to a microcomputer 22. On the other hand, a crystal oscillator 23 and an oscillator circuit 24 output a reference clock pulse, and input it to a pulse counter 25. The counter 25 is counting the number of pulses, and the microcomputer 22 reads an output (ci) of the counter 25 according to a timing (c) of a rise of a rotational pulse (a), calculates tape remaining time and indicates it on a display element 26. A certain rotational frequency Tk and the difference DELTATi between the Tk and the previous rotational frequency is calculated. The DELTATi is proportional to thickness of the tape. Thus whether or not the rotation of the reel is stable is decided depending upon the constant value of the DELTATi, and a remaining amount of the tape is detected quickly and with little errors at the time of starting of a travel of the tape, etc.

Title: Smoothing circuit
Inventor: TATSUTA MASATAKA
IPC: H02M1/14
Filed: 1981-12-28
Abstract: PURPOSE:To reduce the size of a smoothing circuit by associating a large power static induction transistor of depletion mode in the smoothing circuit, thereby reducing the withstand capacity of a peripheral element. CONSTITUTION:Condensers C1, C2 are respectively connected between the source and gate terminals S and G as well as between the drain and gate terminals D and G of a static induction transistor SIT, and the drain terminal D, is connected to one end of the resistor R1 of voltage resistance dividers R1, F2 connected between the output lines and the gate terminal G is connected to the connecting points of the resistors R1, R2. Since voltages divided from an output voltage EO are then applied as a voltage VSG between the source and the gate, the voltage VSG, when the output voltage EO decreases, decreases proportional to the output  voltage. Accordingly, the apparent resistance value between the source and the  gate becomes small from the characteristics of the transistor, thereby increasing  the output voltage EO.
