Title: Production of optical fiber preform and apparatus therefor
Inventor: MIKAMI TOSHIHIRO
IPC: C03B37/014
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an optical fiber preform comprising such a process that a porous clad soot deposited on a core rod is heated externally, and concurrently the lower end of the core rod with no soot deposited thereon is heated separately, thereby heating the soot both externally and internally to effect dehydration and sintering of the soot in a short time. SOLUTION: This method for producing an optical fiber preform comprises the following process: the length of a core rod 1 is set longer by a magnitude of 1, the lengthened portion is left so as not to deposit a porous clad soot 6 thereon, and the porous clad soot 6 is then suspended inside a core pipe 8 with the above portion turned downward; the porous clad soot 6 is then heated with an annular heater 5, and concurrently, the above portion is heated with another heating device 7; thereby the heat applied by heating the lower part of the core rod 1 is transferred through the core rod 1 onto the inner surface of the porous clad soot 6; thus the porous clad soot 6 is heated externally and internally as well, with the result that the time of treating the porous clad soot 6 is shortened and the consumption of expensive helium gas necessary for the treatment is reduced.

Title: Acoustic device
Inventor: SUZUKI EIICHI
IPC: H03F3/20
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To reduce the generation of clip when a voltage level is high by reducing the feedback gain of a negative impedance generating means according to the level of the driving voltage of a speaker, and changing the load voltage amplitude frequency characteristics of an amplifier. SOLUTION: The amplification factor of a voltage control amplifier 20 is changed according to a control voltage Vc. That is, the amplification factor of the voltage control amplifier 20 is made lower according as the control voltage Vc is made higher. A signal detector 22 being a negative impedance generating means detects the terminal voltage of a resistance Rs, and the output signal is converted into direct currents by an AC/DC converter 23. In this case, the level of the negative voltage is indicated by the AC/DC converter 23. The output signal of the AC/DC converter 23 is supplied to a voltage control amplifier 20 as a control voltage Vc. Then, when the input voltage is made higher, the peak part of frequency characteristics is made gradually smaller.  That is, when the load voltage is made high, the amplifier factor of the voltage control amplifier 20 is made low, and the degree of voltage applied due to negative resistance is made small so that the increase of the input voltage of a differential amplifier 1 can be reduced.

Abstract: PROBLEM TO BE SOLVED: To discharge a specimen from a dispensing position in a confirmable state from the outside without dispensation it, when an abnormal of a parent specimen is detected and abnormal detection is carried out, when a specimen such as blood is automatically dispensed. SOLUTION: A container 11 for a main specimen and a container 12 for a sub-specimen are subsequently conveyed through a dispensing position in a state in which they are retained in a rack 13. A tip 18 is inserted to the specimen 11 set at a dispensing position and absorbs the specimen. The specimen is discharged to the container 12 for a sub-specimen in a prescribed amount. When a pressure exceeds a prescribed suction pressure by a blinding of the tip 18 caused by a solidification of the specimen, the pressure sensor 27 detects the phenomenon as an abnormal and imparts it to a control device 15. A quantity of the specimen is detected by a CCD camera and a quantitative abnormal is judged by the control device 15.  In the case where the abnormal is detected, the tip 18 or a marker 22 is dropped off in the container 11 for the main specimen and is discharged so as to confirm it from the outside.

Title: Method for controlling driving motor of table roller
Inventor: MATSUI KIYOYUKI
IPC: B21B39/12
Filed: 1990-12-10
Abstract: PURPOSE:To make the smooth transportation of rolled stock and high-quality rolling possible by increasing droop resistance value when a rolled stock is bitten with a rolling mill and decreasing droop resistance value when the rolled stock is delivered from the rolling mill. CONSTITUTION:A motors 4 which are provided on the front and rear side of a hot rolling mill 1 and with which table rollers 2 are started are controlled. When the rolled stock S is bitten with the hot rolling mill 1 and load-on signal is outputted, droop resistance value is made into a high value by adding droop resistances 8a, 8b and acts in the direction that the rising property of the motors 4 is restrained. When the rolled stock S is delivered from the hot rolling mill 1 and load-off signal is outputted, droop resistance value is made into low value of only droop resistance 8a, because the droop resistance 8b is short- circuited with a relay contact 9a, and acts in the direction that a proper speed responsiveness is given to the motors 4. In this way, the load current of the driving motor is stabilized, matching is attained and the smooth transportation of the rolled stock and high-quality rolling are realized.

IPC: C23C14/48
Filed: 1990-12-18
Abstract: PURPOSE:To neutralize electrified ions completely by arranging an electron current control device to control electron quantity to neutralize the ions electrified on a semiconducting substrate. CONSTITUTION:A semiconducting substrate is housed in a chamber 2, and an ion gun 1 generates ions to be implanted into one main surface of this substrate, and electrons are generated from an electron gun 3 so as to neutralize the ions electrified on the substrate. Here, an electron current control circuit 11 is connected to a vacuum gage 10 to measure degree of vacuum in the chamber 2, and also controls flow rate of the electrons generated by means of the electron gun 3 according to the degree of vacuum in the chamber 2. An emission electric current to flow into a cathode of the electron gun 3 is set to flow abundantly as the degree of vacuum rises while following up the degree of vacuum. Thereby, the rise in the degree of vacuum and the generation of the ions can be neutralized by outgassing from an organic material coat by showering the electrons more abundantly.
