Title: Production of glass and optical fiber
Inventor: TSUJIKAWA KYOZO
IPC: C03B19/10
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To enable the production of an optical fiber that is reduced in OH group content and is excellent in light-transmission characteristics by placing glass starting materials or porous glass material formed by depositing fine glass particles and heavy water in a pressure and heating vessel, heating them until the vessel is saturated with the water vapor under pressure and continuing the heating in an inert gas atmosphere containing heavy water. SOLUTION: Raw materials for glass or a porous glass soot body formulated to a desired composition 9 and heavy water in an amount of 3-10wt.% based on the porous soot body are charged in a crucible 8 and they are mixed. Then, the crucible is placed in a pressure and heating vessel 12 having a heater 11 embedded therein and heated at the temperature that can saturate the vessel 12 with the steam under the pressure of about 5-10kgf/cm<2> (at 150-240 deg.C) for more than 2 days. Then, the glass raw materials or porous glass soot 9 in the crucible 8 is dried, taken out of the pressure vessel 12, transferred to another heating furnace and heated in an inert gas atmosphere or the same containing heavy water at 500-1,000 deg.C for more than 2 hours.

Title: Signal processing circuit
Inventor: GOMI HIROSHI
IPC: H04N9/71
Filed: 1978-03-01
Abstract: PURPOSE: To reduce the number of pins and to enable to connect in multi-stages, by forming and constituting AC coupling circuits so that the attenuation and phase rotation of circuit can not be given effect to the signal processed through the use of the capacitors constituted into IC.  
     CONSTITUTION: Taking the delivery performance (attenuation) of the AC coupling circuits P 1  and P 2  as P 1  and P 2 . The input signal e 5  to the burst phase detection circuit A 5  at greater signal e 1  is independently of the attenuation P 2  and constant regerdless of the dispersion in P 2 . Further, the input signal e 4  of the demodulation circuit A 4  is determined with the ratio of attenuation P 1  and P 2 . In case of IC, the ratio of capacitances can be made with a good accuracy and the constituent element of P 1  and P 2  has disperision toward the trend in the same direction, then e 4  is not almost affected by P 1  and P 2  either. Further, the phase θ p1  and θ p2  between the input and output of the circuits P 1  and P 2  have the same dispersion, resulting is very small dispersion for θP 1 -θP 2 . That is, no dispersion of the phase difference between the burst signal and the chroma signal is caused. Accordingly, even if the capacitor in the AC coupling circuits has an impedance and causes attenuation or phase rotation, no effect on the overall circuit performance is made.

Title: Output controller for generating facility
Inventor: MIYAZAKI YASUHIRO
IPC: H02P9/04
Filed: 1991-02-18
Abstract: PURPOSE:To suppress overshoot and undershoot of a generator by comparing an output set value of a governor with a target output of the generator and switching the time constant of an integrating means to a slower value if the outputs are equal or close to each other. CONSTITUTION:When a high speed control command circuit 9 provides a command to a decision circuit 8, the decision circuit 8 switches a difference-pulse converting circuit (short pulse) 2a to a long pulse difference-pulse converting circuit 2b and further switches the time constant of an integrating circuit 3 to a quicker one. Consequently, a governor output set value PGSET is increased or decreased at a high rate. The PGSET is then fed back and if the difference  PGSET from a target value PGT is zero or close to zero, the difference-pulse converting section (long pulse) 2b is returned to the difference-pulse converting section (short pulse) 2a while furthermore time constant K of the integrating circuit 3 is returned to a slower one. According to the invention, overshoot and undershoot of actual output PG can be minimized.

Title: Externally applied magnetic field supply device for magneto-optical recording
Inventor: KUSANO YOSHIMASA
IPC: G11B5/02
Filed: 1990-01-31
Abstract: PURPOSE:To deal with two different types of recording media by supplying individually the currents to the 1st and 2nd coils in order to generate the magnetic fields of different polarities between both coils for execution of the magnetic field modulation recording and then to generate the same polarity for execution of the optical modulation recording respectively. CONSTITUTION:The 1st and 2nd coils 15 and 17 are provided to generate an external magnetic fields to a magnetic head 11 together with a coil deriver 31 which supplies the current to both coils to drive them. The driver 31 supplies individually the currents to both coils 15 and 17 in order to generate the magnetic fields of different polarities between them in the magnetic field modulation drive. Meanwhile the driver 31 supplies simultaneously the currents to both coils 15 and 17 in order to generate the magnetic fields of the same polarity at both coils in the optical modulation drive. Then these two different types of drive are freely switched to each other. Therefore the inductance is reduced in the magnetic field modulation recording because only one of both coils is used. Then the high field intensity required is secured in the optical modulation recording. Thus it is possible to deal with both specifications of a magnetic field modulation recording medium and an optical modulation recording medium.

As the inner pipes are constituted with plural pieces of the small diameter pipes and natural frequency of the tuyere can be made to little and as the O2 blowing rate can be adjusted in the wide range, the wasteful consumption of large quantity of O2 can be prevented and breakage ratio caused by vibration of the inner pipe can be reduced.

Title: Projection aligner and polarizer
Inventor: KAMON KAZUYA
IPC: H01L21/027
Filed: 1992-02-10
Abstract: PURPOSE:To prevent the dimensional accuracy of a resist from being deteriorated by installing the following: a condensing lens; a projection lens which converges a beam of irradiation light on the surface of a wafer; and a polarizer which is arranged on the pupil face of the projection lens and which converts the beam of irradiation light converged on the surface of the wafer into a polarization provided with a radial polarization face with reference to its optical axis. CONSTITUTION:When a beam of irradiation light is passed through a polarizer 21, it is converted into a polarization provided with a radial polarization face. The light flux of the beam of irradiation light converted into the polarization at the polarizer 21 is converged on a wafer 20 although it is provided with the radial polarization face with reference to an optical axis L. When the polarizer 21 is arranged in this manner, the beam of irradiation light is incident on a main face 20a on the wafer 20 so as to become the P-plarization. The reflectance of the P-polarization is small as a whole as compared with that of an S-polarization, and the reflectance of the P-polarization becomes 0 especially when an incidence angle becomes the Brewster angle. As a result, it is restrained that standing waves due to a beam of reflected light are generated, and it does not happen that the size of a resist is changed according to the film thickness of the resist.

Title: Controlling circuit
Inventor: MURATA RIYOUICHI
IPC: G05B9/02
Filed: 1981-02-20
Abstract: PURPOSE:To stabilize a controller at the time of a fault, by decreasing an output of a correcting circuit to ''0'', and inputting it to a control system as the extent of correction of a target value or the extent of correction of a manipulated variable. CONSTITUTION:When an output of a switching device 22 is ''0'', an output of an element 20 of time lag of first order is reset to an output DELTAr of a computer 7, therefore, DELTAr is inputted to an adder 8 as it is. Subsequently, when the output of the switching device 22 is ''1'', the output of the element 20 is decreased like an exponential function toward a value of ''0'' generated by a zero generator 21, and becomes ''0'' finally. Accordingly, at the normal time, the output of the computer 7 is inputted to the adder 8 as it is, but the moment that the output of the device 22 has become ''1'', the output signal of the computer 7 is intercepted smoothly by inputting a signal gradually decreasing to ''0'' like an exponential function with a set time constant, to the adder 8.
