Title: Injecting device for grout for improving poor subsoil
Inventor: KURIMOTO NAKATOMI
IPC: E02D3/12
Filed: 1979-09-21
Abstract: PURPOSE: To obtain the sufficient strength by a method wherein a stirring tube for grout is moved vertically and rotated and thereby the grout is stirred sufficiently.  
     CONSTITUTION: The injecting device is arranged in a prescribed position. An air spring 3 is operated to move a monkey 2 vertically and the monkey 2 is dropped on the top end of a monkey receiving tube 11. By the shock of dropping, a protecting tube 8 is driven into the ground through the intermediary of a supporting block 1 and a grout-injecting tube 4 and a stirring tube 6 are intruded concurrently into the ground. The grout is supplied from an injection port 40 into the grout-injecting tube 4 and is injected into the ground through a nozzle 41. When the monkey 2 is moved vertically through the air spring 3 and the piston 71 of a cylinder 70 is also moved reciprocally, the stirring tube is moved vertically, while being rotated normally and reversely at every 90°, and thereby the grout discharged from the nozzle 41 is stirred and mixed fully in the ground.

Title: Weed-controlling agent, its production and weed control using the same
Inventor: YOSHIDA SHIGEMASA
IPC: A01N25/12
Filed: 1995-04-20
Abstract: PURPOSE: To obtain a weed-controlling agent having excellent weed-controlling effect by bringing cake resulted from water purifying plants having been discarded because of its no usefulness into each specified granular size and water content. CONSTITUTION: This weed-controlling agent (material) consists of cake resulted from water purifying plants granulated into granules having an average granular diameter of 1-10mm and <=30wt.% water content. Incorporation of 0.1-10 pts.wt. of an allelopathic substance-contg. material (esp. pref. coffee grounds) into 100 pts.wt. of the cake further improves the performance of the agent. Incorporation of 10-50 pts.wt. of lime into 100 pts.wt. of the cake gives another version of this agent excellent in performance to adsorb and remove toxic gasses such as NOx and SOx . Besides, combination of this agent with a water-permeable sheet such as a nonwoven fabric sheet exhibits excellent weed-controlling effect even on weeds such as perennial weeds resistant to a weed-controlling agent alone even in case in which the weed-controlling agent layer is relatively this.

Abstract: PURPOSE:To make it possible to form a gate having a T-shaped section easily and with good reproducibility by a method wherein a gate forming resist pattern, which has such a hole as a resist is left on the base part of the hole in a constant thickness and the width of the section of the hole becomes narrower as the width goes from the base part to the opening part of the hole, is combined with a temporary gate. CONSTITUTION:In case a gate of a field-effect transistor on a semiconductor substrate is formed, a gate forming resist pattern 18, which has such a hole 17 as a resist layer thinner than the thickness of a temporary gate 8 is left on the base part of the hole, the section of the hole is formed into a form that the width of the section becomes narrower as the width goes from the base part to the opening of the hole and the upper end of the gate 18 is exposed, is formed. After that, the gate 8 is removed by etching and a gate material is deposited on the whole surface of the treated substrate 1. Then, the pattern 18 is removed to form the gate. Thereby, a gate having a T-shaped section can be formed with good reproducibility using a simple process and even if the fine formation of the gate is conducted, a gate resistance can be inhibited lowly.

Abstract: PURPOSE:To miniaturize the coupler by connecting an input optical and plural output optical fibers to one face of a waveguide and connecting a total reflecting mirror to the other face of the waveguide. CONSTITUTION:The input optical fiber 12 is connected to nearly the center of one face of the waveguide 11 and the output optical fibers 131-1310 are connected to one face of the waveguide 11 with the fiber 12 at the center.

Title: Preparation of photoconductive cadmium sulfide
Inventor: IKEDA TAKESHI
IPC: G03G5/08
Filed: 1979-09-19
Abstract: PURPOSE: To prevent a photoreceptor containing photoconductive CdS from absorbing moisture and deterioration of photoconductive performance, by dissolving off excessive sulfur present in the inside or on the surface of each CdS crystal suspended in a nonpolar solvent.  
     CONSTITUTION: Photoconductive CdS prepared by the conventional precipitation method is about 10min stirred in CC 4 , filtered after 10min, and dried at about 70°C under normal pressure. The CdS thus obtained is freed of the sulfur contained in the crystals in a preparation process by washing, and even the sulfur contained inside the crystals not washed off even in presence of ion exchange resins is further washed off, resulting in preventing the troubles that the residual sulfur is converted into SO 4  ions due to light, water, and electrification in using the photoconductor, and deteriorates photoconductivity preformance. Moreover, this washing operation enhances photoconductivity, thus permitting the photoconductor to form a superior image under high humidity and to be enhanced in durability.

Title: Optical disk signal reproducing device
Inventor: INADA HIROSHI
IPC: G11B7/00
Filed: 1990-05-14
Abstract: PURPOSE:To attain the accurate reproduction of signals and to ensure the higher density of a track by eliminating the crosstalk produced from the adjacent tracks when the track density of an optical disk exclusive for reproduction is increased. CONSTITUTION:The beams 3a - 3c radiated from an optical head 4 are positioned and applied to an object information track 2 and its two adjacent tracks. The reproduction signals are detected out of three information tracks 2a - 2c independently of each other. These three reproduction signals are inputted to a crosstalk canceler 5 to undergo each suitable filtering processing. Then the filter output signals corresponding to the adjacent tracks are added to or subtracted from the filter output signal corresponding to a desired track. Therefore an accurate reproduction signal is obtained by eliminating the crosstalk signals produced from the adjacent tracks from the reproducing signal corresponding to the desired track. Thus it is possible to accurately detect the reproduction signal even when the track density is increased.
