A method of manufacturing an improved bipolar transistor or BiCMOS having a phosphorus-doped polysilicon emitter electrode is disclosed. The method comprises forming an emitter electrode wherein a phosphorus-doped amorphous silicon film is deposited at temperature not higher than 540.degree. C. and then subjected to low temperature annealing treatment at a temperature of 600.degree. C. to 750.degree. C., under which the amorphous silicon is converted to a polysilicon and the phosphorus present in the amorphous silicon film is diffused into a base region to form an emitter region, followed by high temperature/short time annealing treatment at a temperature of 900.degree. C. to 950.degree. C. so that an activation rate of an impurity in a boron-doped polysilicon base electrode or source-drain regions of MOS.cndot.FET is improved.

A power supply apparatus for arc-utilizing equipment includes a first converter for converting a received AC voltage to a DC voltage. An inverter converts the DC voltage to a high-frequency voltage, which is applied to a voltage-transformer with primary and second windings. A voltage-transformed high-frequency voltage induced in the secondary winding is converted to a DC voltage in a second converter, which is developed between two output terminals. The respective ones of the two output terminals are connected to a torch electrode of the arc-utilizing equipment and a workpiece. A bypass capacitor and a high-frequency voltage generator circuit are serially connected between the two output terminals. A control circuit controls the high-frequency voltage generator circuit and the inverter circuit. The bypass capacitor is connected directly between one of the two output terminals and the high-frequency voltage generator circuit.

A filter is provided for use with an in-tank fuel pump for an internal combustion engine. The filter is disposed within a fuel tank and includes a main filtration chamber connected to an inlet of the fuel pump and a return fuel chamber connected to the engine for introducing thereto return fuel from the engine. The main filtration chamber has an upper side peripheral wall formed from a meshed filter medium. The return fuel chamber is connected to the main filtration chamber in such a manner that the upper side peripheral wall of the main filtration chamber serves as a partition wall between the main filtration chamber and the return fuel chamber. In one embodiment, the return fuel chamber has a peripheral wall formed from sheet or plate impermeable to fluid. In another embodiment, the return fuel chamber has a peripheral wall formed from a meshed filter medium, the meshes of which are smaller than the meshes of the meshed filter medium from which the upper side peripheral wall of the main filtration chamber is formed.

The object of the present invention is to provide various scramble systems and equipments for embodying the scramble systems for omitting unqualified viewers in a pay TV system such as CATV.One of the scramble system according to the present invention is characterized in that a horizontal blanking interval and a video signal interval in at least one specified horizontal scanning line are shifted with respect to the time axis thereof to be transmitted in combination with other horizontal scanning lines in which no shifting operation is conducted. Another scramble system is characterized in that a horizontal line in which a horizontal blanking interval is deleted and the remained video signal interval is shifted within the time interval equal to the thus deleted horizontal blanking interval in addition to the above system. A further scramble system apart from these systems is characterized in that a pedestal part of a specified horizontal scanning line within a vertical blanking interval is compressed with respect to the time axis thereof, whereas a pedestal part of another desired horizontal scanning line within the same field is expanded for a time interval corresponding to the thus compressed pedestal part. And, a still further scramble system is characterized in that an audio signal as well as the video signal is also scrambled.

Preferably, the fractionation may be effected by ultrafiltration. The interferon inducers thus obtained have a molecular weight of from about 30,000 to about 3,000,000 and are of potential interest for preventing and treating various diseases of humans and animals caused by viral infection.

A transfer-printing process and apparatus for transfer-printing from a master card onto a work piece. The process starts by manual insertion of the master card into a gap provided between press rollers. By the insertion of the master card, the work piece is fed into a work piece path and the surface thereof is wetted during its movement along the path. The work piece thus fed and the master card sustained between the gap are registered with each other as desired and pressed for transfer-printing by the rotation of the press rollers. The work piece and the master card are then delivered to the insertion inlet of the master card.
