Title: Plasma treatment device
Inventor: SHIMADA YUTAKA
IPC: C23F4/00
Filed: 1992-02-24
Abstract: PURPOSE:To prevent the occurrence of discharge of electricity between electrodes for generating plasma and a manifold at the time of plasma-treating a semiconductor wafer. CONSTITUTION:A discharge trapping electrode 9 is provided so as to surround the outer periphery of a reaction tube 1 between a manifold 2 holding the tube 1 and electrodes 5 and 6 for generating plasma and the electrode 9 is earthed by connecting the electrode 9 to a base plate 20. Since the electrode 9 is nearer to the electrodes 5 and 6 than to the manifold 2, discharge of electricity does not occur between the tube 1 and manifold 2, but between the tube 1 and electrode 9, even when the gas pressure in the tube 1 drops. The same effect can be obtained when the internal surface of the manifold 2 is nearly tightly covered with an insulating cover made of quartz instead of providing the electrode 9, because electric charges generated by the polarization of the insulting cover disappear due to electric charges of the opposite polarity in the manifold 2.

Title: Video signal reading device
Inventor: YAMASHITA HARUO
IPC: H04N1/04
Filed: 1985-04-05
Abstract: PURPOSE:To shorten the reading time to one per several minutes of the conventional time by plural delaying means to delay the output of the counter to give the timing for reading the picture element on the basis of the horizontal synchronizing signal and plural registers to store the output of an A/D converting device. CONSTITUTION:A counter 3, to which a reading starting signal (e) is given, presets horizontal initial position data which an initial position setting means 2 outputs. A counter 4 presets the output of the counter 3 each time the horizontal synchronizing signal is inputted, and when the picture element clock, which an oscillating device 1 outputs, arrives at the preset pulse number, a carry signal is generated. Picture element data in which a video signal is A/D- converted by an A/D converting device 5, are stored by a register 6 by means of the carry signal to generate a counter 4, and a register 7 stores the carry signal by a delaying means 8 by means of the signal in which one clock is delayed. By repeating for a scanning line each at the section of one field, two lines are read for the video signal in the longitudinal direction of the screen.

Filed: 1985-04-05
Abstract: PURPOSE:To reproduce the message of a caller by providing a cordec related to the analog sound signal, a dynamic RAM to store the digital signal output of the cordec and a means to send the analog signal output of the cordec to the sound converting means. CONSTITUTION:When a sound signal is received, a calling sound and a sound are loudspoken from a speaker 4, the sound signal is converted to a low speed pulse clumn and accumulated to a dynamic RAM6. The stored sound information can be reproduced to an audible sound by the switch operation of the user at any time. For a cordec 5, an ADM system is used which can modulate the sound signal of 0.3-3.4kHz to a low pulse of 16kbps and also decode it. For a dynamic RAM6, the drum of 256kbit per chip is used, the sound signal of 16sec per chip can be stored and reproduced, and consequently, the sound signal of about one minute by four chips can be handled. Thus, since the sound signal can be heard over and over again after receiving, the message can be heard without fail.
