Title: Production of porous parent material for optical fiber
Inventor: YOKOTA HIROSHI
IPC: C03B37/018
Filed: 1983-11-28
Abstract: PURPOSE:Gases as starting materials for optical fiber are jetted out of the oxyhydrogen flame burner to form porous parent material for optical fiber wherein the amount of the glass jetted out is altered periodically to form the objective glass parent material in high raw material yield and high deposition rate. CONSTITUTION:Starting gases such as SiCl4 and GeCl4 16, H2 gas 18, Ar gas 19, O2 gas 20 are jetted from the fivefold burner 13 to the parent material 12 which is being pulled upward gradually under rotating by means of the lift 11. The starting gas for glass is hydrolyzed in the oxyhydrogen flame to stack the porous parent material on the rod 12. In this case, the controller 21 is used to open and close periodically valves 15, 17 for supplying starting gases. Thus, the efficiency of starting gases for glass such as SiCl4 and GeCl4 is improved and the porous parent material for optical fiber is formed at elevated speed.

Filed: 1989-09-01
Abstract: PURPOSE:To prevent the positional displacement of a lead and a bump by a method wherein the pattern of an electrode for the bump is exposed and developed to a photo-resist first, the electrode is plated with gold to form the bump, the pattern only of the lead is exposed and developed to the photo-resist, and a coNductor layer is etched from the surface to shape the lead. CONSTITUTION:The surface of a conductor layer 6 stuck onto an insulating layer 1 is coated with a photo-resist 11 and the rear with a protective resist 12. The pattern only of a bump is exposed and developed, and an opening section shaped is plated with gold. Since the patterning only of a lead is conducted to the same photo-resist, a gold plating process is executed in a chamber, in which ultraviolet rays are shielded, so that the photosensitivity of the photo-resist 11 is not lost. The lead is formed through etching while using ferric chloride or cupric chloride as an etchant, and the resist is peeled, thus completing a film Carrier in which the bumps 3 are shaped at the front end sections of the leads 2.

Filed: 1986-09-24
Abstract: PURPOSE:To make it possible to control the magnitude of steering forces according to the driving condition of a vehicle by switching steering characteristics according to the driving conditions such as the vehicle speeds, maneuvering conditions and road conditions. CONSTITUTION:A 1st operation means 3, inputted with and based on information values V such as a vehicle speed, etc. detected by a sensor 1, calculates a driving condition index J1 while a 2nd operation means 4, inputted with and based on a steering angle theta detected by a steering angle sensor 2, calculates a road condition index J2. A compensation means 5 inputted with the driving condition index J1 which is changing every moment converts the index to a compensated driving condition index changing in steps and taking decimal values. A control current operation means 6, inputted with and based on the compensated driving condition index, calculates a control current value I corresponding to a vehicle speed, driving condition and road condition at the corresponding time while a control means 7 applies the control current value I to a solenoid control valve 30.

Title: Low-nox combustion method and burner therefor
Inventor: KAWAMOTO MASAO
IPC: F23C99/00
Filed: 1990-08-29
Abstract: PURPOSE:To achieve low NOx generation by a method wherein the whole fuel is burnt with a portion of combustion air at a high intensity to generate an oxygen-free flame or combustion gas, the remainder combustion air is blown from the periphery to form an external region, and the residual fuel contained in the combustion gas in an internal region is burnt. CONSTITUTION:Fuel F and a portion of combustion air A1 supplied into a high intensity combustion chamber 3 are burnt at a high intensity. NOx is generated in a large amount because of high temperature resulted from high intensity combustion. When a flame or combustion gas is blown from the high intensity combustion chamber 3, an oxygen-free zone is produced due to high intensity combustion, and comes in contact with a second flow of combustion air A2 after retained for a certain time period, so that residual fuel is slowly burnt. When the oxygen-free state is established, NOx generated due to high intensity combustion is reduced and tuned into 0 just before the combustion gas comes in contact with the second flow of combustion air. The flame or combustion gas in an internal region 6 comes in contact with the second flow of combustion air A2 and the residual fuel is slowly burnt. A small amount of NOx is generated, however, as NOx is continuously reduced in the oxygen-free zone in the internal region 6, the amount of NOx to be generated is remarkably reduced.
