Title: Ink jet head and manufacture thereof
Inventor: AZUMI JUNICHI
IPC: B41J2/16
Filed: 1999-07-26
Abstract: PROBLEM TO BE SOLVED: To prevent electrostatic pulling of a diaphragm is prevented by pressure variation occurring in the gap between the diaphragm and a parallel plate electrode when an actuator is operated by sealing the gap. SOLUTION: The ink jet head comprises an ink liquid chamber substrate 10, individual electrodes 21 positioned oppositely to a diaphragm 11 through a gap G, and an electrode substrate 20 on which the individual electrodes are arranged wherein pad regions 23 for applying a voltage to the individual electrodes are provided on the surface of the electrode substrate. The diaphragm is deformed electrostatically by applying a drive voltage between the diaphragm and the individual electrodes in order to eject an ink drop from a nozzle 15.  In the individual electrode pad regions 23, the gap between the diaphragm 11 and the individual electrodes 21 is choked with an insulating resin material 29 having coefficient of thermal expansion similar to those of the electrode substrate 20 and the ink liquid chamber substrate 10 and the gap G is led to the outside through an open groove for preventing pressure variation.

Title: Filament winding
Inventor: BESSHO HISAMI
IPC: B29C70/16
Filed: 1986-09-04
Abstract: PURPOSE:To device to wind a tape of broad width uniformly in thickness and besides precisely to the extreme extent, by distributing a delivering fiber to a mandrel and drawing it into the uniform size and thereafter winding it on the mandrel while a constant gap is being kept between the distributing section set up at a carriage traverse and an axial symmetry mandrel. CONSTITUTION:First, a continuous fiber is distributed through a distributing section 13 set up at around the delivering point of a fiber and then this distributed fiber is drawn into the uniform size by an axial symmetry body 15, so that the surplus spread or the bias spread of the fiber at the delivering point (guide bar 15a or the connecting point with 15a) can be avoided by the operation of the distributing section, which makes the guide eye stable and prevents the string disorder. Consequently, even if a delivering tape to the mandrel is a broad one, no gap between the fiber is found and the thickness becomes uniform. Especially, if a cylinder 12 is capable of rotating with an axis phi as the center of the rotation, a stable delivery of the fiber is guaranteed because the guide bar 15a or 15a' is kept vertical to the guide eye all the time at any wrapping angle.

Title: Transmission regulation method for mobile communication system
Inventor: SAKAMOTO TOSHIHIRO
IPC: H04W84/14
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To attain effective utilization of a radio frequency by giving a transmission regulation function to a mobile station side. SOLUTION: A mobile station side is given a transmission regulation function. In this case, a maintenance and administration terminal(MAT) 2 is a maintenance terminal connected to a wireless services controller(WSC) 1. A procedure for downloading transmission regulation data to a signal subscriber unit(SSU) 4 to be used is performed with this MAT 2. The SSU 4 executes a procedure for downloading and a procedure for transmission regulation. The SSU 4 has an ROM for storing transmission regulation data downloaded from the MAT 2. Therefore, after a radio line is accessed from the SSU 4, the discrimination of the transmission regulation, which is to be performed by a host local switching station(LS) 6, can be performed on a terminal side. Thus, it is not necessary to access the radio line and to transmit an invalid calling to an host LS station 6.

Abstract: PURPOSE:To maintain the dust scraping effect during a long period of time by pressing a dust scraping tip against the belt surface through a support frame by a spring so that even if the tip is worn away, the tip is brought into close contact with the belt. CONSTITUTION:A rectangular hollow support frame 6 is disposed below a driving pulley 2 of a conveyer 1 in such a manner as to extend over the width of a belt 1'. Dust scraping tips 5 are respectively fixed through fitting plates 4 on both longitudinal ends of belt 1' the support frame 6. Each one end of tension springs 7 is hooked on both side ends of the support frame 6, the other end thereof being fastened on a side plate of a chute 8 with a pin 9, so as to bring each tip 5 into contact with the surface of the belt 1'. This results in that the support frame 6 is moved with the drive of the belt 1' until it is balanced with the spring 7. Thus, the tips are always brought into suitable contact with the surface of the belt 1' to remove dust efficiently.

Abstract: PURPOSE:To provide a printer applicable for facsimile or the like miniaturized and easy to manufacture by drawing ink retained in an ink hole onto the surface of an ink carrier with the application of voltage to an electrode to transfer. CONSTITUTION:A plain paper 14 is inserted between a rotary drum 2 and a transfer paper press roller 6 and the rotary drum 2 turns at a fixed speed in the direction of the arrow (a) for printing or the like of the plain paper 14. A digital signal voltage is applied to electrodes 34-39 corresponding to pixels. For example, as ink holes 23 and 27-31 come right below the electrodes 34- 29 with the rotation of the rotary drum 2, only the ink 5 retained in the ink holes 23, 27 and 28 facing the electrodes 34-36 is polarized and drawn on to the circumferential surface 3 of the rotary drum 3 by an electrostatic force to swell. The swelled ink 5 is left on the circumferential surface 3 by a surface tension even after passage through the elctrodes 34-35. Therefore, ink 5 in the ink holes 23, 27 and 28 is transferred onto the plain paper 14 for printing or the like.

Filed: 1990-08-08
Abstract: PURPOSE:To easily equalize the intensity of recording laser beams between two master optical disks by providing a means which changes polarizing state of the recording laser beams and a polarized beam splitter and dividing a recording laser beam into two parts by the beam splitter. CONSTITUTION:A polarized beam splitter 7 is provided together with a means 6 which changes the state of the recording laser beam. Then a recording laser beam is divided into two parts by the splitter 7. A wavelength plate 6, for example, is provided between a laser device 4 and the splitter 7 as a means which changes the polarizing state of the recording laser beam. Thus the intensity ratio between two laser beams can be optionally changed up to 100:0 from 0:100 with use of a 1/2 wavelength plate 6. In other words, the intensity ratio can be changed between two laser beams when the plate 6 is turned against the optical axis of the incident light. As a result, the intensity of the recording laser beams can be equalized on a substrate 1.
