Title: Automatic stacker for plate-shaped body
Inventor: MOTOHIRO SHIYUNICHI
IPC: B65H33/08
Filed: 1979-03-06
Abstract: PURPOSE: To stack plywoods rapidly without interrupting conveyance of the plywoods by a method wherein plywoods are stacked on one block while the stacking of plywoods on the other block is stopped and the latter block is at the stand-by for conveyance or next stacking.  
     CONSTITUTION: The height of piled plywoods is detected by photoelectric tubes 22, 22', and a lift 31 is lowered to keep constant the height of the upper face of the stack from the floor. Every time when the counting by photoelectric tubes 15, 15' reaches the number of plates corresponding to one step, cylinders 24 are moved back and the forth, a carry-out conveyor 27 is moved back and the forth by the action of  a cylinder 30, and the plywoods are stacked zigzag by arranging plates 21. With a  set number of plates thus stacked on a block A counted by photoelectric tubes 2, 2', a conveyor 3 is lowered to the position of broken lines; thereafter, the plywoods fed in are guided to a block B, and stacked zigzag on the block B with steps formed for every predetermined number of plates in the same way as above.

Filed: 1995-01-20
Abstract: PURPOSE: To reduce switching noise caused by a parasitic capacitance by connecting a transistor whose gate and source are connected together to the output terminal of the current switch circuit and applying a signal in complementary with a control signal to its gate. CONSTITUTION: A switching transistor(TR) 1 (2) selects the output current of a constant current source CS to a positive output terminal 10p and negative output terminal 10n. The gate voltage of the TR T1 is changed to supply a switch current ISW from the gate of the TR T1 to the positive output terminal 10p through a parasitic capacitance Cgds1 between the gate and source in a transient state. On the other hand, a control signal P is fed to the gate of the TR T1 and the inverse of the signal P is fed to the gate of a TR T3 to absorb a current flowing to the parasitic capacitance Cgs1 of the TR T1 by the gate of the TR T3 thereby cancelling switching noise.

IPC: H01F27/28
Filed: 1987-02-06
Abstract: PURPOSE:To eliminate an eddy-current loss in a conductor of a strand and reduce a space between strands by using for a strand a ribbonshaped substance having width almost equal to a gap between core flanges and performing winding in a single row. CONSTITUTION:A bobbin-shaped open magnetic circuit type core 1 has flanges 1b on both ends of a main leg 1a. Ribbon-shaped strands 2 having width almost equal to a gap interval B between the flanges 1b are wound round the main leg 1a in piles. An insulating film 4 is wound round the main leg 1a and the strands 2 are wound on the film 4. Then, a magnetic flux passing through the gap between the flanges 1b is almost vertical to the surfaces of the flanges 1b having little parallel components. Consequently, an eddy-current loss is not generated in conductors 2a of the strands 2. Thereby, a space between the strands 2 is reduced.

Title: Power amplifier
Inventor: ISHIZAKI YASUHIRO
IPC: H03F1/02
Filed: 1983-02-21
Abstract: PURPOSE:To attain excellent power efficiency by constituting the power amplifier that a single operation where output current is applied from a low voltage power supply and a cascode operation where the current is applied from a high voltage power supply are changed over depending on the signal power. CONSTITUTION:When a signal power is small, a load current flows from the 2nd power supply 23 having a low voltage via the 2nd power TR28 and when the signal power is increased, the load current flows from the 1st power supply 13 having a high voltage via the 1st power TR18 and the 2nd power TR28 being in saturated state. Thus, the power efficiency is kept excellent over a wide dynamic range of the signal power. Thus, a small heat sink is enough and power TRs with less collector loss is enough for the application because the power TRs are operated in cascode at a large output current.

Title: Drive circuit for semiconductor switch
Inventor: ISHIBASHI HIDEAKI
IPC: H03K17/732
Filed: 1984-02-17
Abstract: PURPOSE:To apply the circuit for the operation at a low frequency by forming a current via a current transformer from a main circuit current as a forward bias current of a main semiconductor switch when the said switch is turned on, compensating a voltage drop of the said current to prevent the saturation of the current transformer and using the said current as a reverse bias current when the switch is turned off. CONSTITUTION:A forward bias transistor (TR)7a is turned on with an ON signal e10, a reverse bias FET8a is turned off, most of a forward bias current is obtained in a way of positive feedback from the main circuit current. The current transformer 4 has no voltage source 11 and the magnetic flux is increased in a direction opposite to the increasing direction only with the main circuit current. Since FET5c, FET5a repeat on/off with the increase/decrease of the output of an integration device 12, the current transformer 4 is not saturated for a long time. When an OFF command is given from a command section 10, the forward bias current becomes a reverse current of the TR1 through a ternary winding 4c, a reverse bias current from the FET8a is added and the TR1 is turned off. Thus, the current transformer 4 is reset by circulating the exciting energy of the current transformer 4 to the forward bias power supply 7b by the winding 4c.
