IPC: G03G5/08
Filed: 1986-01-31
Abstract: PURPOSE:To quickly and thoroughly execute cleaning of powder generated in the stage of forming an amorphous silicon layer on a substrate surface by the glow discharge of a gaseous raw material by providing ejection ports for an etching gas to a glow discharge region in the stage of converting the above- mentioned powder to the etching gas. CONSTITUTION:The Si-contg. gaseous raw material is introduced from a gas piping 8 and a high-frequency voltage is impressed between a dummy substrate 2 and an inside electrode plate 3 to generate the flow discharge, thus forming the amorphous silicon layer on the surface of the dummy substrate 2. The powder of Si sticks simultaneously onto the inside electrode plate 3 in this stage and gives an averse influence to the formation of the amorphous silicon film. The etching gas such as CF4 is ejected from the plural ejection ports 12 of a gas ejection pipe 13 disposed to the discharge region between the inside electrode plate 3 and the dummy substrate 2 and the etching gas is subjected to the electric discharge by which the remaining Si powder is gasified and is thereby quickly and thoroughly removed. The adverse influence thereof on the formation of the next amorphous film is thus eliminated.

Filed: 1980-02-21
Abstract: PURPOSE:To make easy the maintenance and arrangement of input circuit and the failure detection, by turning off the common line of signal input in response to the control output of processor and turning on each signal input at a bundle. CONSTITUTION:The input section 1 of three-input and a processor 2 are provided with a digital input diagnostic section 3 having the functions to turn off the common line CL of the input section 1 and to turn on the input lines S1, S2, S3 at a bundle.

Title: Phase detecting circuit
Inventor: MURATA EIICHIROU
IPC: H03L7/095
Filed: 1980-02-21
Abstract: PURPOSE:To stop the oscillation in the case of an out-of-synchronism and then secure automatic restarting of oscillation when the synchronism is secured again, by using an out-of-synchronism detecting circuit. CONSTITUTION:When an out-of-synchronism occurs at the time point (B), the output (d) obtained by dividing the output (c) of the exclusive OR circuit 20 by the FF21 is turned into the signal having a different pulse duration from the output (a) of the reference signal oscillating circuit 11 and the output (b) of the divider circuit 16. Accordingly the outputs given from the Q terminals of FF22 and 23 to which the signal (d) is applied at the data input terminal D are turned into the outputs (e) and (f). And the output of the exclusive OR circuit 24 turns into ''0'' to be applied to the reset terminal R of the counter 26 via the inverter 25. Thus the counter 26 is reset. As a result, the signal (h) sent from the output terminal Q' turns to ''1''. Thus the output signal controlling circuit 17 is cut off, and the output signal supplied from the voltage control variable frequency oscillating circuit 15 does not emerge at the output terminal 18. When a synchronous state is obtained again, the control circuit 17 conducts again after a prescribed time.

IPC: H04W88/02
Filed: 1993-02-09
Abstract: PURPOSE:To improve handleability by adjusting automatically the sound volume in accordance with whether a hand-free adaptor exists or not. CONSTITUTION:When an adaptor B is not connected to a connector 40, a signal processing part 20 reads a set value of a RAM 31, and controls electronic volumes 28, 32. An alarm signal from a tone generator 27 passes through a base band control part 24, the electronic volume 28 and a selector 30 and is sent to a loudspeaker 23. A sound signal expanded by the control part 24 is outputted from a loudspeaker 22. When it is decided that the adaptor B is installed, the volumes 28, 32 are controlled by an output adjustment value of the RAM 31. The alarm signal from the generator 27 is sent out to the connector 40 from a mixer 29, and outputted from a loudspeaker 101 through an amplifier 103 of the adaptor B. The sound signal expanded by the control part 24 is adjusted by the volume 28, and thereafter, passes through the amplifier 103 through the mixer 29 and the connector 40 and is outputted from the external loudspeaker 101. In such a way, the sound volume adjustment at the time of detachment and attachment is obviated and the handleability is improved.

IPC: G03B42/02
Filed: 1990-01-31
Abstract: PURPOSE:To obtain a reproduced picture without distortion by applying one correction only at reading and recording of a series of picture while only obtaining jitter at reading and correcting it at recording in the lump. CONSTITUTION:A picture reader 10 detects a timing when a light beam 17 crosses detectors 31, 32 and a jitter detection circuit 33 obtains a read jitter signal SJI representing the main scanning speed for each main scanning, outputs the signal synchronously with a picture signal SD to provide only a jitter measuring function. A photosensitive sheet 51 is fed in a direction of Y2 in a picture recorder 50. A beam 53 of a laser light source 52 transmits through an acousto-optic modulator 54 and subject to intensity modulation based on the picture signal SD and reflected and deflected in a polygon mirror 19 driven at a high speed by a motor 55. Then the light is made incident to the sheet 51 via a lens 57 and a mirror 58, subjected to repetitive main scanning in the direction X2 and the picture signal SD is reproduced or recorded. The read jitter signal SJI is inputted to a correction clock circuit 61, in which a correction clock CA is obtained and optical modulator 62 is driven based on the picture signal SD in the timing CA. Since the mirror 56 is driven at a high speed, jitter is less and neglected in the recorder 50 and a reproduced picture is obtained with high quality.
