Title: Cmos drive circuit
Inventor: YAMAMOTO SATOSHI
IPC: H03K19/0175
Filed: 1992-03-06

CONSTITUTION:The drive circuit is provided with two sets of differential pairs 31, 32 supplied from the same current source transistor(TR) 33 and whose gates receive the same input, the one differential pair 31 drives a load Ro and the other differential pair 32 supplies a monitor current Im proportional to the load drive current. Then the gate of the current source TR 33 is controlled via a negative feedback loop L so that the monitor current Im is constant independently of DC level fluctuation. Furthermore, the drive circuit is also provided with a monitor circuit 6 controlled by the same gate voltage VG as that of the current source TR 33 and supplying a current proportional to the output current and the negative feedback loop L is used to control the gate voltage VG so that the current Im of the monitor circuit is made constant.

Title: Production unit for semiconductor device
Inventor: INOUE YOSHIRO
IPC: H01L21/50
Filed: 1986-03-06
Abstract: PURPOSE:To prevent the peeling of solder plating on a lead frame, and to obviate the deterioration in quality due to the adhesion of solder chip onto a semifinished product by guiding the lead frame, on which a semiconductor device is loaded, by a line contact. CONSTITUTION:A groove 2b avoiding a contact with a semiconductor element 1 on a lead frame 4 is formed in the longitudinal direction of a carrying rail 2, the cross sections of both side walls of the groove are formed to a ridging shape forming a smooth curved surface, and both side edges of the lead frame 4 are supported by the top sections of the ridging-shaped support surfaces 2a. Accordingly, since the carrying rail 2 is brought into line-contact with the lead frame 4 and frictional resistance due to a surface contact is reduced, the generation of solder chips due to the peeling of solder plating is minimized, and solder chips fall from the ridging-shaped projecting edges in the rail 2 even when chips are generated, thus preventing the clogging of solder chips into the rail 2 and adhesion and the like to semifinished products.

Abstract: PURPOSE: To provide a winding diameter detector of low cost but high reliability which calculates the decrease in the winding diameter of an unwinder from the measured values of rotational frequency of drivers to determine the winding diameter of a winder.  
     CONSTITUTION: A material 14 unwound by th unwinder 10 is guided on a winder drum 15 to the winder 11. The unwinder 10 and the winder drum 15 are dirven by motors 12, 16. The rotational frequency of the unwinder and the winder drum are detected by rotary electric generators 13, 17. A divider 22 divides the output signal V of the rotary electric generator 17 by a signal πn produced by multiplying the output signal n of the rotary electric generator 13 through a multiplier 21. The output of the divider 22 is applied to an adder 27 through a squarer 23 and a polarity inverter 26. The winding diameter D1 before the start of winding and the winding core diameter Dw of the winder 11 are applied to the adder 27 through squarers 24, 25 so that these diameters are added to each other. The winding diameter D3 of the winder 11 is determined through a square root calculator 28.

Title: Oscillation control circuit
Inventor: IWASAKI TOMONOBU
IPC: H03B5/02
Filed: 1983-03-24
Abstract: PURPOSE:To facilitate the manufacture of an IC and to increase the degree of freedom of the selection of an oscillating element by detecting the kind of the oscillating element according to whether oscillation occurring at an external terminal for connecting the oscillating element is large or small, and making only the corresponding oscillation loop effective. CONSTITUTION:A CR element is connected to external terminals EX1 and EX2, and when CR oscillation occurs, the waveform at a point (a) has a small amplitude. Consequently, an inverter I4 of a detecting circuit DET generates an H- level output and an inverter I3 generates an L-level output to set a flip-flop FF, whose Q output goes up to the level H to select the oscillation loop LP2 of a CR system. On the other hand, when a crystal system oscillates while a crystal oscillator is connected, the waveform at the point (a) has a large amplitude. Consequently, the outputs of the inverters I3 and I4 are both at the level H at a peak part and at the level L at the bottom part. Consequently, the flip-flop FF is reset and the Q' output goes up to the level H to select the oscillation loop LP1 of the crystal system.

IPC: C12H6/02
Filed: 1994-03-22
Abstract: PURPOSE:To distill efficiently even at the normal temperature and under normal pressure by setting an ultrasonic wave evaporator beneath the liquid surface of a material to be distilled in a distillation tank and emitting ultrasonic waves to atomize the material to be distilled and accelerate the distillation. CONSTITUTION:An ultrasonic wave evaporator 4 is set on a position immersed completely by a material to be distilled in a distillation tank 1, and pulse is supplied to the ultrasonic wave evaporator 4 by a circuit 3, and ultrasonic waves are emitted from the inside of the material to be cleaned to an inner-tank gas phase to generate the atomization and evaporation. At that time, the effect, in which the concentration of a certain component in mist formed by the ultrasonic wave emission is different from the general concentration of the component in the material to be distilled, is generated. For instance, ultrasonic waves are emitted from a liquor distillate or distillate filtrate in the distillation tank 1 to the inner-tank gas phase to accelerate the atomization and evaporation to generate the mist by the concentration of a low boiling point component containing ethanol which is higher than the concentration of the distillate or its filtrate. The vapor thus generated passes through a duct 12 and reaches a collecting column 13, and is cooled and concentrated by a zigzag tube 14 and collected into a distilled liquid storage tank 15 as distilled liquid 16.
