Title: Chemical injection control method in coagulating sedimentation treatment
Inventor: TANAKA YOSHIAKI
IPC: B01D21/30
Filed: 1991-02-15
Abstract: PURPOSE:To maintain and control required injection quantity of chemical liquid even if concentration of solid content in chemical liquid changes by inputting water quality measurement value of raw water and specific gravity measurement value of chemical liquid into a computing element to compute chemical liquid injection rate, computing chemical liquid injection quantity from the computed value and raw water flow rate measurement value, and controlling opening of a control valve based on injection quantity computed value. CONSTITUTION:Measured values of a turbidity meter 14 and alkalinity meter 15 of raw water are inputted into a computing device 9 to compute injection rate of solid content in chemical liquid which is determined based on the quality of raw water. Said injection rate is converted to injection rate as chemical liquid using measured value of a hydrometer 11. The computed value of injection rate is converted to chemical liquid flow rate by means of measured value of a raw water flow meter 13 to make it a set value of a controller 10. A control valve 8 is controlled by means of the controller 10 so that the result of control is measured by a chemical liquid flow meter 12 for feedback. As a result, even if the concentration of solid content in the chemical liquid changes, required injection rate of chemical liquid can be maintained and controlled.

IPC: C23C16/30
Filed: 1986-03-04
Abstract: PURPOSE:To deposit a high quality film with a high speed by a method wherein a film composed of laminated two or more layers with different Fermi levels is deposited on a microwave transmitting window and a DC voltage is applied to the direction of expanding a depletion layer to avoid degradation of microwave introducing efficiency. CONSTITUTION:When a p-type semiconductor film is formed on a substrate 4, an n-type semiconductor film is prepared on a microwave transmitting window 2 on the surface of a reaction chamber side. Material gas of predetermined composition is introduced 3 while the substrate 4 is being kept at a required temperature. A microwave is introduced through the window 2. p-type layers are deposited on the substrate 4 and on the n-type layer formed on the inner surface of the window 2 and a depletion layer is formed by a p-n junction. A DC voltage is applied to the direction of expanding the depletion layer while being controlled until the formation of the p-type layer on the substrate 4 is finished. As the depletion layer reduces the absorption of a microwave, a deposited film with uniform quality and characteristics can be formed on the substrate 4 with a high speed. It is to be noted that the same effect can be obtained with any composition of the semiconductor film on the window 2 if the film is composed of laminated two or more layers with different Fermi levels.

Title: Production of optical waveguide element

IPC: G02B6/12
Filed: 1987-02-27
Abstract: PURPOSE:To obtain an optical waveguide element operable in spite of its large thickness of waveguide film by carrying out the deposition of optical waveguide layers comprising oxide dielectric thin films contg. Pb on a substrate at higher temp. of the substrate in the initial and final stage of the deposition than the temp. of the substrate in the middle stage of the deposition. CONSTITUTION:In the stage of deposition for forming optical waveguide layers 12 comprising Pb-contg. oxide dielectric thin films such as a compound oxide (PLZT) material, the deposition is carried out at high substrate temp. in the initial and final stage of the deposition than the substrate temp. in the middle stage of the deposition. Thus, the PLZT thin film (2.600 refractive index) 12 for forming the optical waveguide layer is inserted between PLZT thin films 13a, 13b having smaller refractive indices (refractive index 2.598). Although the guided light passes through the layer having higher refractive index, the film thickness of the waveguide layer satisfying the single mode condition in the film direction can be increased due to the small difference of the refractive indicates between the upper layer 13b and the lower layer 13a, excitation of light on the terminal surface is caused more easily, and an optical waveguide element capable of simpler coupling of input-output light and suitable for mass-production is obtd. Further, scattering of light at the interface is reduced and the loss of guided light is also reduced by the increase of the waveguide layer 12 thickness and the decrease of the difference of refractive indices at the interface.
