Title: Method of modulating semiconductor laser
Inventor: HABARA TAKASHI
IPC: H04B10/524
Filed: 1986-09-29
Abstract: PURPOSE:To generate a short optical pulse without a pattern effect, by superimposing a modifying current, which is smaller than the current value when an RZ pulse current is '1', on the RZ pulse current when it is a '0', and driving a semiconductor laser with a newly formed RZ pulse current. CONSTITUTION:When an RZ pulse current Isa is '1', an optical pulse is generated, and a carrier density is rapidly decreased. When the current Isa is a '0', the optical short pulse is not generated. Therefore the carrier density N is not decreased rapidly. The relationship with the current value is set at a suitable value for the rapid decrease of the carrier density N at the time of the '1'. Thus even if the short optical pulse is not generated at the '0' value, the carrier density N is made to be Ni at the rising time point of the next RZ current pulse. Therefore, the carrier density N at the rising time point of the RZ pulse both for the values of '0' and '1' always becomes a constant value Ni. A previous modulating pattern Ip does not depend on the value of '0' or '1'. Thus the short optical pulse having the constant position, width and amplitude is obtained.

Title: Spreading of artificial turf containing sand
Inventor: HIGUCHI YOSHIKAZU
IPC: E01C13/08
Filed: 1993-09-17
Abstract: PURPOSE:To prevent filled sand from getting hard and keep artificial turf in a good condition, by appropriately keeping the water contents of combined specified pile threads with specified filling sand. CONSTITUTION:Pile threads made of nylon yarn as a basic material are planted and stuffed with sand to complete artificial turf. In this time, so-called heat- setting, that is heat-treatment (wet or dry heating) at 110-140 deg.C for 5-15min, is not applied for the pile threads in advance. Silicic acid content in the sand is 90% or more as recommendable figures. Since the pile threads expend the volume after rain, the sand must be prevented from hardening. When water is sprayed on the lawn in fine weather, the sand gets bulky, and hence, it can be prevented from hardening. In this way, the water absorptivity of the pile and the water-retaining characteristic of the sand bed can be improved.

IPC: H03H7/21
Filed: 1985-10-17
Abstract: PURPOSE:To prevent the deterioration in the VSWR over a wide and and to extract an incident wave with a required amplitude and phase distribution by making each main line length tying each coupler different and providing a line correcting the electric length of the main line between a coupler and an output terminal. CONSTITUTION:A part of power of an incident wave to input terminal P0 is extracted from output terminals P1-P5 on the way of propagation through the couplers 1-5 sequentially via the main lines 6-9, and the amplitude of the power wave is formed into a required amplitude distribution by changing the coupling amount to the couplers 1-5. Further, phases phi1-phi2 of the extracted power wave are decided depending on the electric length of the lines 6-9 and of the correction lines 11-15. Thus, the deterioration in the VSWR of a series feeding circuit eliminated over a broad band frequency because the reflection of the couplers 1-5 is not overlapped in phase at a specific frequency due to the different length of the lines 6-9 and the fluctuation of the amplitude and phase of the waves extracted at the terminals P1-P5 is reduced.
