Title: Nozzle plate for glass fiber spinning
Inventor: SHIOURA KOZO
IPC: D01D4/02
Filed: 1989-04-14
Abstract: PURPOSE:To accomplish the stable spinning of fine glass fiber of high quality by making up many nozzles projected from a flat plate part with larger diameter parts on the flat plate side and smaller diameter parts on the tip side and by regulating both the respective inner diameters and lengths to be specified. CONSTITUTION:Many nozzles 12 are projected from a flat plate part 11 and formed to make a nozzle plate 10 for glass fiber spinning. The nozzles 12 are made up with the larger diameter parts 13 on the flat plate 11 side and the smaller diameter parts 14 on the tip side, the inner diameters of the smaller diameter parts 14 being defined as 0.3 to 1mm and their lengths as 0.5 to 2mm, the inner diameters of the larger diameter parts being defined as 1.1 to 2.5mm an the length of the nozzle 12 projected from the flat plate part 11 as 4 to 6mm. Thereby, as a nozzle hole 14a of smaller diameter is formed under a nozzle hole 13a of larger diameter, the flow of molten glass can be made lower and also the molten glass delivered can be made more resistant to the influence of the variation in the ambient conditions, leading to stable delivery. Therefore, a corn 16 of a stabilized state can be formed at the tip of the nozzle 12, thus stably producing fine glass fiber 17.

Title: Optical fiber polarization detecting device
Inventor: TSUBOKAWA MAKOTO
IPC: G01J4/04
Filed: 1986-04-25
Abstract: PURPOSE:To extract components in mutually 90 deg. - or 45 deg.-different polarized directions in the middle of propagation in an optical fiber by using an optical fiber type separator. CONSTITUTION:Signal light propagated in the optical fiber 1 is coupled with an optical fiber 2 by an optical fiber type coupler separator 3. The optical fiber 2 consists of a normal single-mode optical fiber or birefringent optical fiber, two orthogonal polarized components of coupled light corresponding to the polarized state of the signal light are separated by a polarization separating device 4, and their intensity values are detected by photodetectors 5 and 6. Here, when the normal optical fiber is used as the optical fiber 2, the optical fiber is fixed so that the light wave does not change in polarized state while propagated in the optical fiber 2. Further, the coupling efficiency of electric power at the optical fiber type coupler separator 3 is adjustable by varying the coupling length, etc., so the coupling efficiency is so set that the emitting light of the optical fiber 2 can be detected by the photodetectors 5 and 6.

IPC: F24F11/04
Filed: 1979-07-27
Abstract: PURPOSE:To improve the breakdown voltage of a transistor controlling voltage and the loss of a collector by a method wherein a resistor or a coil are connected in parallel with the primary voltage control circuit and in series with a motor. CONSTITUTION:One terminal of a rectifying circuit 4 is connected in series with an AC power source 1 and a single-phase induction motor 3. A transistor 5 and a base circuit 6 are connected to the other terminal of the rectifying circuit 4, and the number of revolution of the motor is controlled by the voltage which the transistor bears. Resistors 8, 9 and a coil 7 are connected in parallel with the transistor 5 and in series with the motor. Thus, the maximum voltage applied to the transistor and the loss of a collector decrease to three fourths if the impedance of the resistors and the coil is taken as the threefold of the impedance of the motor. The breakdown voltage and allowable loss increase equivalently, and use having scope to rating is enabled.

Title: Image forming device
Inventor: MIYAKE NOBUYUKI
IPC: G03G15/08
Filed: 1985-05-07
Abstract: PURPOSE:To prevent color mixture and to obtain a copy of high quality by scattering part or the whole of a developer to a no-image area on a latent image carrier and removing said part or whole of the developer from the surface of its developing roller. CONSTITUTION:A bias voltage of hundreds - thousands volts which has the same polarity with toner put in each developing unit is applied to a developing roll 5a in a rotation stop state before an electrostatic latent image on the surface of the photosensitive body begins to be developed and developing rolls 4a and 6a which are also in the rotation stop state and positioned on the upstream and downstream sides of said developing roll 5a. Therefore, the no-image area on the surface of the photosensitive drum is developed forcibly by the respective developing rollers 4a, 5a, and 6a. Mixed color toner on the developing roll 5a which is selected by said forcible development is carried to the no-image area on the photosensitive body before the electrostatic latent image on the surface of the photosensitive body reaches the developing rolls, thus preventing an image area from being developed with the mixed color toner.

Title: Fine rolling in tea manufacturing and its device
Inventor: WATANABE KOUJI
IPC: A23F3/12
Filed: 1978-08-04
Abstract: PURPOSE: To effect the fine rolling operation precisely according to the tea leaves states, by adjusting the gap between the rolling plate and the presser of a tea manufacturing device.  
     CONSTITUTION: Tea leaves, rolled in the intermediate rolling device in the previous stage, are charged on the bottom d, mostly formed into masses with the scraper 21, pressed and rolled by the presser 19 while being transferred on the rolling plate 2 back and forth. After the repeated operations for a given time, the leaves are finely rolled.

A given pressure is thus applied to the leaves by lifting the plate 2 suitably to make the fine rolling operation proceed while pushing the internal moisture out for given time. The finely rolled tea leaves are then sent to the dryer in the next step.

Title: Gas pressure welding method of steel material
Inventor: SHINOHARA BONPEI
IPC: B23K20/00
Filed: 1979-07-27
Abstract: PURPOSE: To improve the close adhesion of pressure contact surfaces by suitably heating and pressurizing the pressure contact end faces of steel materials to produce bulge then stopping the pressurizing operation and heating these down to their melting temperature or lower thereby joining the end faces.  
     CONSTITUTION: Pressure contact end faces 1a, 2a of reinforcing bars 1, 2 are butted to each other and the pressure contact portion 3 thereof is heated by a gas burner 6 and is pressurized by a hydraulic unit. Next, the gas burner is reciprocatively moved in the longitudinal direction of the reinforcing bars 1, 2 to widely heat the pressure contact portion 3 across its both sides and this produce bulge. Here, the pressurizing operation is stopped (this does not mean to make pressurizing zero) and the temperature is allowed to lower down to the melting point of these reinforcing bars or lower, in the case of, for example, a high maganese nonmagnetic steel (melting point about 1,270°C), down to 1,100W1,200°C. This requires about 1W 4min, when the burner 6 is stopped and this completes the pressure welding. This  pressure welding method is suited for high manganese nonmagnetic steels and low  alloy steels containing Cu, Cr, Ni, Sn, etc.
