When a vertically moving carrier 27 provided in the pick-out position is elevated and receives the stacked frames 11, a stopper is inserted in between the lowest and the second lowest frames 11. When the carrier 27 is moved down, the rodlike product on the lowest frame 11 is transferred onto a conveyor 26 and the frame is transferred onto another conveyor 30. After the carrier 27 is elevated again into contact with the bottom of the stacked frames 11, the stopper 24 is retracted. After that, the carrier 27 is moved down by the thickness of one frame. The stopper 24 is then protruded. The lowest frame 11 is thus sequentially separated.

Abstract: A chair of the tilting type which includes a base (10), a seat (11) and back (12), with the base (10) pivotally supporting the seat (11) with two opposite non-parallel links of a four bar non-parallel linkage (24), with one of the opposite links (38, 39) extending at (45, 47) to support the back (12) and also being formed to provide an arm rest (44). The four bar linkage (24) is duplicated on each side of the chair by forming the two opposite non-parallel links or cranks (29, 30, 38, 39) from the upturned ends of the tubes (26, 27) which pass through the base (10) in parallel but vertically offset fashion, the base (10) thus forming the fixed bar of the linkage (24) with its opposite bar or coupler being formed by the seat (11). A spring (62) within the base (10) is operative on one of the tubes (26, 27) to urge the chair to an upright position. The tubes (26, 27) are pivotally connected to the seat (11) and one of the tubes (27) extends and is fixedly connected to the back (12) in a manner to emphasize the isolated and separate appearance of the seat (11) and back (12). With the above construction the seat (11) and back (12) both tilt in their proper natural body support positions but in a respective ration of about 1 to 3. The chair thus obviates some of the problems of prior chairs where only the back tilts or both the seat and back tilt as a unit

Title: Three-phase balanced reactive power detecting circuit
Inventor: SATOU SHINJI
IPC: G01R21/00
Filed: 1979-06-08
Abstract: PURPOSE: To detect reactive power simply and dfficiently, by using an analogue switch, a half-wave shaping circuit, and a filter circuit to constitute a circuit.  
     CONSTITUTION: Current IR of one phase out of three phases, the R phase in this case, is flowed to R 1  through current transformer CT and is taken out as a voltage signal and is input as the data signal source of analogue switch 2. The voltage signal of other two phases, the ST phase in this case, is input to half-wave shaping circuit 3. Half-wave shaping circuit 3 converts the voltage waveform of VST to a waveform required for activating analogue switch 2. By operating the switch only in the half period of VST in this manner, prescribed IR waveform is obtained. Next, positive-polarity components and negative-polarity components of this waveform are cancelled by filter circuit 4, and the rest value is output as a measured value. Consequently, reactive power of advance phase and delay phase can be taken out simply.
