Title: Method and apparatus for generating small bubble in liquid
Inventor: FUIROZU MANETSUKU BAGATSUTO
IPC: B01F3/08
Filed: 1989-06-15
Abstract: PURPOSE: To introduce fine bubbles into liquid by ejecting gas from an orifice 15 disposed in the liquid and simultaneously ejecting the liquid at a velocity sufficient for forming a local shearing field from another orifice disposed opposite thereto. CONSTITUTION: The gas is ejected from the orifice 15 of a conduit 14 for gas disposed in the liquid. Simultaneously the liquid is ejected at the velocity sufficient for forming the local shearing field from the orifice 16 of the conduit 12 for the liquid disposed opposite to the orifice 15. As a result, the fine bubbles may be generated in the liquid. Namely, the generation of the fine bubbles in the liquid in a range where the volume flow rate ratio of the gas and the liquid is larger than 20:1 from about 1:1 is made possible. The orifices 15 and 16 are preferably disposed opposite to each other so as to form an angle from about 20 deg. to 160 deg.. Further, the orifices are particularly preferably disposed to face each other at an angle of 90 deg. with each other on the same plane.

Title: Developing device
Inventor: TATEYAMA SUSUMU
IPC: G03G15/09
Filed: 1995-06-16
Abstract: PURPOSE: To prevent toner from scattering into a machine of developing device by rotating an electrode plate to a photoreceptor around the bias roll shaft, and keeping the distance between the photoreceptor and the electrode plate nearly invariable. CONSTITUTION: A first developing device 2 rotates around a developing device supporting shaft 13 by a cam 14 to perform retracting operation with respect to the photoreceptor 1. At this time, a developing roll 3 is retracted with respect to the photoreceptor 1 while the distance between the roll 4 and the photoreceptor 1 is kept nearly invariable. A pressing force works on the electrode plate 5 in the direction toward the photoreceptor by a spring 7. The pressing force also works on the roll 4. Therefore, the intervals between the photoreceptor 1 and the plate 5, between the photoreceptor 1 and a holding part, and between the photoreceptor 1 and the roll 4 are kept constant in the case retracting operation is performed with respect to the photoreceptor 1 by the device 2.  A bias current for preventing toner scattering is supplied from a bias power source to a scraper 9, the roll 4, the member 6, and the plate 5.

IPC: B60K17/06
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To enable a transmission gear to be inexpensively switched from for lower speed travel to for higher speed travel in a working vehicle. SOLUTION: When an output shaft 13 of a main change gear 15, which is interlocked with the engine side, is connected to an input shaft 17 coupled with the wheel side by a connecting tool 16 so that they can be integrally rotated, the wheels are driven on the lower speed side. When the connection of the output shaft 13 with the input shaft 17 by the connecting tool 16 is released, and a speed increasing transmission gear 44 is loaded, an input gear 42 of the speed increasing transmission gear 44 engages with an output gear 38 provided on the output shaft 13, and an output gear 43 engages with an input gear, or the connecting tool 16 of the input shaft 17. The speed increasing transmission gear 44 speeds up the turning force of the output shaft 13 to transmit the increased force to the input shaft 17, and thus to drive the wheels in the high speed side.

Title: Method for compression molding plastic lens under heating
Inventor: TAKAGI MASAO
IPC: G02B1/04
Filed: 1982-09-01
Abstract: PURPOSE:To produce a large-sized thick plastic lens with precision in a short molding cycle, by compression molding wherein a high-frequency energy is employed to heat the mold surface. CONSTITUTION:The surface of a lens blank that is thicker than the intended lens and whose outer diameter is smaller than that of the intended lens is melted by a heated mold, and it is compressed followed by cooling to make the intended lens. In this method, the mold 2 is provided with a resonant chamber 8 that constitutes a resonant space in cooperation with the cavity surfaces 4, and a high-frequency energy is fed. That is, the high-frequency energy from an oscillator 5 is transmitted via a controller 6, and an impedance matching box 7 to the resonant chamber 8 (the reference numerals 11a-11e are waveguides), and due to the ohmic loss of the wall current generated on the cavity surfaces 4, the surface layers quickly heat up to reach a prescribed molding temperature within a short period (in case when a temperature detector 12 detects the set temperature, the controller stops the operation of the oscillator 5).

IPC: G02F1/1345
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in display quality in a display part even when electrostatic charges enter from a dummy electrode, by forming the dummy electrode in a region between the display part and a sealing material to flatten a substrate and dividing the dummy electrode into a part near the sealing material and a part near the display part. SOLUTION: A region which does not substantially act as a display part is formed between a sealing material 3 and a display part consisting of an ensemble of pixels as an overlapped part of pixel electrodes 4 and scanning electrodes 5. A large number of dummy electrodes 15 are arranged all over the aforementioned region mainly in order to flatten the processed face of a transparent substrate 1 facing a liquid crystal. Each dummy electrode 15 is divided into two parts of a dummy electrode 15A positioned as the sealing material 3 side and a dummy electrode 15B positioned as the display part side. Thus, sparks due to the electrostatic charges in the pixel electrodes 4 in the display part through the dummy electrode 15 can be avoided.
