Filed: 1985-07-18
Abstract: PURPOSE:To execute transferring of a bucket and a regulation plate holder in good timing by regulating the guide pins of the regulation plate holder and the bucket by means of a slider. CONSTITUTION:When a motor 88 turns and the slider 26 moves in the direction to insert a magnetic sheet pack, the bucket 27 moves together with the slider 26 because its guide pins 54A is pressed on the stair part 26A of the slider 26 by the effect of a spring 55. Thereafter the guide pins 54A and 54B enter the regulating grooves 66A and 66B of the side plate 25, restricting the horizontal movement, and said pins 54A and 54B descend being guided by tapered parts 76B and 78B.

Title: Field/frame conversion system
Inventor: KOBAYASHI YASUHITO
IPC: H04N9/86
Filed: 1985-07-18
Abstract: PURPOSE:To prevent an S/N from deteriorating owing to the delay operation of a field signal by delaying the field signal in an FM-modulated state and performing arithmetic mean operation after FM demodulation and before deemphasis operation. CONSTITUTION:Demodulated signal from FM demodulators 14 and 27 are inputted to an adder 30 through an attenuator 29. Then the arithmetic mean operation between a through FM-demodulated signal and an FM-demodulated signal which is delayed by one horizontal scanning period is carried out by an adder 30 and attenuators 29 and 31. This arithmetic mean operation prevents V jitters from being generated owing to field/frame conversion. Then, a deemphasizing circuit 32 obtains a luminance signal Y of a base band, which is mixed with chrominance components C by a mixing circuit 33, amplified by an amplifier 34, and outputted as a playback color video signal.

Title: Junction type field effect transistor
Inventor: KANAMORI SHIYUUJI
IPC: H01L21/337
Filed: 1977-12-27
Abstract: PURPOSE: To avoid the reduction in thermal noise, by holding the threshold voltage and the reverse voltage, increasing the mutual conductance, and decreasing the gate diffusion resistor, by shortening the region in which mesh shaped gate regions are crossed over and the substrate electrically.  
     CONSTITUTION: In the N channel J-FET, the N type epitaxial layer 2, P +  type substrate pick up region 3, P +  type gate region 4, N +  type drain region 5; and N +  type source region 6 are formed on the P type semiconductor substrate 1. Further, the regions in which the gate regions 4 of longitudinal and transversal direction are crossed, form the substrate pick up region 3, then they are shortened to the semiconductor substrate 1 at the same time. As a result, the gate width contributing to the resistor equivalent to noise source is the distance from the substrate pick up region 3 at the circumferential part separating the epitaxial layer 2 to the regions crossed with the gate region 4. Thus, the gate diffuion resistor is reduced to a half the conventional resistor and the noise voltage can be reduced.
