Title: Lightning horn insulator device
Inventor: NAKAYAMA TETSUYA
IPC: H01T4/14
Filed: 1989-12-15
Abstract: PURPOSE:To miniaturize a device by placing the tip of a pair of arc-inducing horns at almost symmetrical positions to the side and retaining a preset clearance longer than a gap for an aerial discharge in the space thereof to a discharge electrode on the grounding side. CONSTITUTION:A suspended insulator is suspendedly connected to the supporting arm 1 of a column via an upper connection to support a wire 5. Arc-inducing horns on the charged side are formed by horns 25A, 25B, which have the tips placed at almost symmetrical positions to the side toward a wire passage, so that a clearance C3 between the arc-inducing horn on the charged side and the discharge electrode of a lightning insulator 8 can be made larger. When the whole device is oscillated by the effect of wire vibration and wind pressure, there is no occasion that this clearance C3 is smaller than an aerial discharge gap G. When abnormal voltage resulting from lightning is applied to the wire, current in such a case is discharged in the aerial discharge gap and flow through a non-linear resistance element built in the lightning insulator 8 into the supporting arm of the column. It is thus possible to realize a small-size and lighter-weight device.

Title: Ink jet recording device and recording method in said device
Inventor: SHIOTANI MAKOTO
IPC: B41J2/21
Filed: 1990-11-30
Abstract: PURPOSE:To make the impact interval as short as possible by a constitution wherein, a plurality of ink drips are discharged from a plurality of discharge ports to the same position on the material to be recorded. CONSTITUTION:Ink drips being discharged from the first discharge port make impact upon a recording paper 2. The dot A, together with the movement of the recording paper 2, after approximately 100 microseconds, transfers to the position of the dot B, while, the ink drips being discharged from the second discharge port neighboring to the first discharge port make impact. By repeating the same action, one complete pixel is formed. The number of ink drips to form one pixel is decided according to the density of the pixel to be formed. As the next process, the discharge port 1 performs the second ink discharge after 500 microseconds of the first ink discharge; thereby, the forming of the second pixel is started. In the same manner, the second, the third,... the thirty- second discharge ports perform ink discharge with the lags of 100 microseconds each respectively. By this procedure, a particular pixel is formed by a plurality of ink drips. While the above-mentioned procedures of pixel forming are repeated sequentially one by one, a drum 3 is rotated for one revolution.
