Title: Overcurrent protective circuit
Inventor: HATAMOTO YOSHIYUKI
IPC: H02M3/28
Filed: 1992-03-04
Abstract: PURPOSE:To keep a normal control state over a rectifying and smoothing circuit, and provide stable continuous operation, by controlling a pulse gate circuit and decreasing an output voltage abruptly when an overcurrent for load is detected in a magnetic amplifier-type stabilizing-unit side circuit, in a multiple output power device. CONSTITUTION:When an overcurrent detecting unit 6-1 detects an overcurrent in an on-load current provided from a rectifying smoothing unit 4 in a multiple output power device, a control unit 1 provides a driving signal to a driving circuit 8 and shortens an on-state to drop each output voltage. Also when an overcurrent detecting unit 6-n detects an overcurrent in an on-load current provided through a magnetic amplifier-type stabilizing unit 5, the control unit 1 provides a signal to a pulse gate circuit 7 and shortens the pulse width of the driving signal, which is provided from the driving circuit 8 to a switching element 2-n. Then, the rectifying smoothing unit 4 is not affected though the output voltage of the magnetic amplifier-type stabilizing unit 5 is dropped during the overcurrent state. Consequently, the overcurrent protective function is made stable.

Abstract: PURPOSE:To miniaturize a P channel-transistor only by the amount of a change section into a Schottky junction of a source, and to obtain the structure of a CMOS semiconductor device, the degree of integration thereof can further be improved, by bringing the source at the same potential as a substrate for the P channel-MOS transistor to the state of the Schottky junction. CONSTITUTION:A field insulating film 7 is formed, a gate insulating film 2 and a gate electrode 3 are shaped and patterned to form an insulating film 7 on the gate electrode, while a source region is coated with a resist film pattern 22, boron is implanted to a drain region, and the drain region 5 is shaped through heat treatment. The resist film pattern is removed, and a platinum electrode 20 is applied, and patterned, thus completing the titled semiconductor device. The platinum electrode may be employed as the drain electrode as it is at that time. An N channel-MOS transistor is also formed at the same time, ions are implanted separately, and heat treatment after ion implantation is also conducted simultaneously. Accordingly, since the heat treatment of arsenic and boron is conducted at the same time, the semiconductor device can be miniaturized by the amount of a change section into a Schottky junction of a source when the source only in a P channel-transistor is brought to the state of the Schottky junction.

In a reproduction time both a plunger shaft 33 and the arm 31 are pulled inward with the reproduction signal, and the arm 34 is turned in the opposite direction to the solenoid 30 against a tension spring 40. Then an erasion head 20 is detached from a tape 90 via the shaft 35. The solenoid 30 is actuated by a pulse signal of a short time, and the head 20 is pressed to and removed from the tape surface by means of a permanent magnet in the solenoid 30 and the self-supporting function of the spring 40. Thus the mechanism of an erasion head device can be simplified and stored in a small space. Furthermore the errasion current is eliminated in a video recording time, and therefore no erasion current producing circuit is needed.

Filed: 1989-02-27
Abstract: PURPOSE:To decrease video information to be erased for an insertion recording period with simple circuit constitution by generating a signal for a prescribed insertion recording period with an insertion recording period generating section as a signal forming the insertion recording period in video information. CONSTITUTION:A gate pulse generating circuit 11 sends an H level pulse for only a period when a character signal is desired to be inserted in a reproducing video signal synchronously with the reproducing video signal. An insertion recording changeover switch 10 is closed only when the set pulse is at an H level, the character signal is amplified by a recording amplifier 12 and fed to a changeover switch 13. The switch 13 is switched to the position of a terminal 13a when the pulse is at an H level and the character signal from the amplifier 12 is fed to a video head 14. Then the character signal is recorded and inserted in the reproducing video signal by the head 14. Since the horizontal and vertical period in the video signal is a prescribed preset period, the original picture part to be erased through the insertion of the character signal is reduced.

Abstract: PURPOSE:To manufacture a roll having excellent strength, abrasive resistance, and toughness, by forming a melt-sprayed layer on the surface of a roll-core material by plasma melt-spray in an non-oxidative atmosphere, and further hot processing the outermost layer of it. CONSTITUTION:A melt-sprayed layer entirely devoid of interposing oxides is formed on a core material of roll by plasma spray in a vacuum, or in a nonoxidative atmosphere formed by an inert gas such as Ar, etc. or a reducing gas such as H2, etc. In forming a multilayered melt-sprayed layer, the surface of the roll-core and the lower coated layer are plastically deformed by the collision between the surface and high speed metallic particles in the plasma melt-spray, which results th same effect as in a case of hot rolling, and further, the outermost layer having high strength and toughness is obtained by hot processing the layer by forging or rolling, etc. Further, when the next melt-spray is performed in a state that the surface temperature of the previously formed melt-sprayed layer is higher than the decomposition or recrystallization temperature of carbide, the hot forging effect is still more improved.
