Title: Plasma cvd system
Inventor: SHIRAISHI YASUSHI
IPC: C23C16/50
Filed: 1986-06-20
Abstract: PURPOSE:To maintain the uniformity of a growing film by devising the structure of the process gas ejecting holes of the shower electrode plate, thereby supplying gas to the peripheral portion more than to the central portion.

IPC: B41J9/127
Filed: 1982-08-20
Abstract: PURPOSE:To obtain a printer capable of clearly setting the fitting angle of printing hammers at the time of design and requiring no regulation after being assembled by a method in which the warping angle of a flexible type supporter when types come into contact with the surace of a platen is equalized with the fitting angle of the printing hammers. CONSTITUTION:Since a warping angle (i) at the point P of a flexible type supporter 6 when a type 5 comes into contact with the printing point P of a platen 1 is an integration of fine warping angles DELTAi at each moment, the warping angle (i) is equal to an integration of turning angles DELTAj at each moment. As a result, it becomes equal to the inclined angle or fitting angle alpha of the striking line of a printing hammer 3 at the center point Q of type. If i=SIGMADELTAi=SIGMADELTAj=alpha and the fitting angle alpha of the printing hammer 3 is equalized with the warping angle (i) of the flexible type supporter 6 at the center point P of the type on the face of the platen 1, the center Q of the type 5 comes into contact with the printing point P, printing pressures at the both upper and lower ends of the type 5 are equalized, and therefore, uniform printing without defects can be obtained.

Filed: 1994-06-27
Abstract: PURPOSE:To prevent temperature drift of a signal transmission time of a transmitter and a receiver, and prevent the deterioration of the measuring accuracy from occurring due to the effect of the temperature drift. CONSTITUTION:A pulse S is sent from a transmitter 3 in synchronization with a reference pulse P, and the corresponding radio wave is transmitted from a transmitting antenna 4. The radio wave reflected from an object to be measures is received with a receiving antenna 6 and detected with a receiver 7. Thus the reflected signal R' is obtained. The radio wave, which is leaked from the transmitting antenna to the receiving antenna, is also detected with the receiver 7 by the same way, and the leaked wave r' is obtained. First and second pulse generators 8 and 21 track R' or r' and output the acquired pulses R'' and r'', respectively. First and second time measuring circuits 9 and 22 detect the time difference tb=ts+ta+tr or tc=ts+tr between R'' or r'' and the reference pulse P and generate the corresponding voltages Vb=etatb and Vc=etatc, respectively. A differential circuit 14 outputs the difference Vout=etata. In the expressions, ts and tr are the signal transmission times of the transmitter and the receiver, and ta is the reciprocating propagation time between the object to be measured and the antennas.
