Title: Production of uniform droplet group
Inventor: WAKABAYASHI MINORU
IPC: C08L29/04
Filed: 1991-12-26
Abstract: PURPOSE:To efficiently produce uniform droplet groups by filtering a raw material liquid through a filter installed just before many nozzle holes in dropping the raw material liquid in the perpendicular direction under vibrating conditions in the vertical direction and forming the droplets. CONSTITUTION:A suspensionlike or an emulsionlike raw material liquid containing a solid, a gel or a liquid is dropped from many nozzle holes in the perpendicular direction while forming droplets under vibrating conditions in the vertical direction. In the process, the raw material liquid is filtered through a filter having an opening of <=1/3, preferably <=1/5 the diameter of the nozzle holes installed just before the nozzle holes to prevent the nozzle holes from being clogged with foreign materials. The rectified raw material liquid is then passed through the nozzle holes to efficiently produce droplet groups having a uniform particle diameter. For example, an apparatus equipped with a nozzle 2 fixed to a nozzle holder 3 and the filter 14 installed just before the nozzle 2 is used to feed the raw material liquid from a liquid feed line 13 thereinto and the droplet groups are dropped while vibrating the whole nozzle holder in the vertical direction.

Title: Electro-optical display device
Inventor: TAKEMURA YASUHIKO
IPC: G02F1/136
Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To improve the yield by supplying a signal from a third signal line to a gate of a fourth thin film transistor through at least a third thin film transistor. SOLUTION: A pulse signal VG is sent to an upper selection line. In such a case, the signal VD is sent to a signal line, and a TFT (Tr1) of an upper pixel becomes on-state, and the signal V1 becomes a voltage state, and a second TFT (Tr2) of the upper pixel becomes the voltage state also. Then, though the pulse signal VG' is sent to a lower selection line, since the signal line isn't in the voltage state, the signal V1' doesn't become the voltage state. Then, the TFT (Tr1') is in off-state, and the second TFT (Tr2') of a lower pixel keeps off-state also. On the other hand, after the pulses of both selection lines are interrupted, the signal is sent to a common voltage supply line. Thus, a voltage is supplied to an upper pixel electrode through the Tr2 being on-state, and the pixel becomes a constant voltage state.  On the other hand, in the lower pixel, since the Tr2 is in off-state, the pixel electrode isn't in the voltage state.

Abstract: PROBLEM TO BE SOLVED: To prevent excess heating of an X-ray tube. SOLUTION: This X-ray tube comprises a bulb container 13 forming a vacuum chamber and having a window 30 to transmit X-ray through. X-ray is generated by the operation of an anode assembled body and a cathode assembled body in the bulb container and the generated X-ray is radiated to a patient or an object to be inspected through the X-ray transmissive window 30. A shield 32 which transmits X-ray is connected with the bulb container 13 and installed so as to transmit X-ray at first the shield 32 and then the X-ray transmissive window 30. The shield 32 prevents all of the electrons generated during X-ray generation from having contact with the X-ray transmissive window 30 and protects the X-ray transmissive window 30 from being over-heated.  Moreover, an electrode 50 formed in a part of the bulb container 13 near the X-ray transmissive window 30 may be employed to prevent secondary electrons from reaching the X-ray transmissive window 30.

Title: Ink jet type recording head
Inventor: CHIYOU SHIYUNKA
IPC: B41J2/055
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To stabilize ink droplet discharge characteristics by connecting an ink tank having a buffering function via a communicating passage extended in an arraying direction of pressure generating chambers near an ink channel, thereby effectively attenuating a pressure change of a reservoir without introducing a complexity of a structure. SOLUTION: At the stage of finishing filling of an ink in a recording head, piezoelectric vibrators 11, 12 are deflection-displaced to pressurize pressure generating chambers 3, 4. The ink is discharged as droplets from nozzle openings 7, 8, and partly reversely fed to a buffer tank 22 via ink supply ports 5, 6 and a communicating passage 2. When a pressure of the ink of the tank 22 is raised due to the backflow of the ink, an upper surface 25 of a wide area is elastically deformed to suppress a rise in the ink pressure as much as possible. The pressure of the ink reversely fed from the chamber can be absorbed by the tank. Thus, a crosstalk is prevented without introducing a complexity of a structure of the recording head, thereby stabilizing a discharging performance of the ink droplet.
