Title: Electromagnetic focusing type colour picture tube
Inventor: SHIMADA KUNIO
IPC: H01J29/68
Filed: 1979-09-28
Abstract: PURPOSE:To reduce the influence of the magnetic field component which crosses perpendicularly to the course of side beam by making the distribution of magnetic field in the course of electron beam asymmetrical on the fluorescent surface side and the cathode side. CONSTITUTION:On the fluorescent surface side of an annular permanent magnet 4, a yoke 20 having a large outer diameter and asymmetrical shape to the cathode side is arranged. Due to the existence of this yoke 20, the distribution of magnetic field at the electron beam passage is made asymmetric on the fluorescent surface side and the cathode side, and the displacement of the side beam in Y direction at the inlet of deflecting magnetic field is made zero or nearly zero. Therefore, the aberration between three electron beams is nearly eliminated even in the case of horizontal deflection.

Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To convert silicon of desired thickness into high melting point metal by exposing silicon deposited selectively to hexafluoro metal gas and regulating the gas flow rate and one or a plurality of CVD process parameters. SOLUTION: For example, a blanket layer 36 of insulating material is deposited to cover a substrate entirely. The blanket layer 36 is then etched selectively to leave a side wall spacer 38 on the opposite sides of silicon layers 32, 34 on a source region 14 and a drain region 16 and an insulating top wall 30 is removed. Subsequently, it is exposed to gas high melting point metal hexafluoridein in the same environment as CVD, thus converting a gate silicon layer 26, the source silicon layer 32 and the drain silicon layer 34 to a high melting point metal. In this regard, gas flow rate and CVD process parameters are regulated such that silicon of desired thickness is converted into high melting point metal.

Title: Proximity detecting method for centering of signal within dynamic range of peak-detecting proximity detector
Inventor: MOODY KRISTANN L
IPC: G01B7/14
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To obtain a proximity detecting method in which a binary output voltage is centered automatically by a method wherein an ambient magnetic field is sensord, a voltage comprising a directly related amplitude is generated and the binary output voltage of a proximity detector having the transition of one polarity is output on the basis of an amplified signal voltage whenever the track of one polarity reaches a prescribed point. SOLUTION: A Hall-voltage amplifier generates an analog signal voltage Vsig having the track of one polarity corresponding to the passage of a magnetic substance. A reference voltage VP2 and a reference voltage NN2 which are equal to tracks going in the positive direction and the negative direction of a nearest peak in the signal voltage Vsig are generated. A DC offset limiting voltage VA and a DC offset limiting voltage VB which are the upper value and the lower value of the center in the dynamic range of a detector are given. When the central value VOS of voltage Vsig is larger than the limiting voltage VA, the signal voltage Vsig at the output of the amplifier is moved wholly to the negative direction. In addition, when the central value VOS of the signal voltage Vsig is smaller than the limiting voltage VB, the signal voltage Vsig is moved wholly in the positive direction. Therefore, the central value VOS is kept between the limiting voltage VB and the limiting voltage VA within the dynamic voltage range.

Abstract: PURPOSE: To make possible continuous focusing by providing differentiating and integrating circuits, etc. and discriminating whether the position of a lens is before or behind the position where it focuses.  
     CONSTITUTION: The detecting signal of a photo detecting means 4 is supplied to an integrating circuit 22 by way of a shift register 10 or the like. As the output of the integrating circuit, the differential crest value output integrated along the characteristic curve 40 of crest type according to the distance D on the optical path between a lens 2 and photo detecting means 4 is obtained. Here, if the focus is matched, the output level of the integrating circuit 22 becomes maximum because the image on the photo detecting means 4 is high in contrast. The distance D on the optical path of this time is let to be d. Next, the output of the integrating circuit 22 is supplied to an integrating circuit 24 and when D=d, no output voltage is generated at all. When D<d, the output voltage in the positive direction is obtainable and when D>d, the output voltage in the negative direction.

Filed: 1981-08-10
Abstract: PURPOSE:To eliminate blocking of a channel, by correcting the erroneous ''significant'' state of access key indicating the use of the channel when this state is set by noise. CONSTITUTION:In case that a controller 4 checks whether the access key indicating the use of a channel is in the ''significant'' state by noise or the like or not, logical 1 is set to a channel access inhibiting key (B). When each transmitting device detects logical 1 of the key (B), it does not perform the access for data transmission, and it resets the access key of a used channel to logical 0 after one circulation of this channel if this channel is used for data transfer at this detection time. Consequently, if access keys set to logical 1 exist after a prescribed time from the time when said controller 4 sets logical 1 to the key  (B), it is discriminated that these access keys are set to the ''significant'' state by noise, and these access keys are reset to logical 0 forcibly through a signal line 106, a recovering part 14, a signal line 101, and a shift register 10.
