Patent JP-H029213-A (JP)
Title: Surface acoustic wave filter
Inventor: MISHIMA NAOYUKI
IPC: H03H3/08
Filed: 1988-06-27
Abstract: PURPOSE:To simplify the manufacture process, to improve the manufacture yield and to reduce the manufacture cost by constituting each comb-line electrode by the 1st area exciting a surface acoustic wave and the 2nd area whose electrode pitch is formed to the size due to the characteristic and adopting the electrode structure having a large bulk mode conversion. CONSTITUTION:The areas opposite to each other in the input side comb-tooth electrode 12 and the output side comb-tooth electrode 13 are constituted as so-called split electrode being nearly a lambda/8 electrode having the electrode pitch of nearly lambda/8 electrode, where lambda is a wavelength of a propagated surface acoustic wave SAW. No acoustic reflection of the SAW is caused in the split electrode as shown in figure (b). Similarly, the reflected wave caused by the electrodes 31-34 from each electrode end face is cancelled together by taking the middle point of the electrode 21 as a reference point even in the electrode structure of equal pitch as shown in figure (c). Thus, no acoustic reflection is caused in both the areas A, B. Then an undesired wave is eliminated without applying a sound absorbing agent to the area B.

Title: Image forming device
Inventor: NUMAZU TOSHIHIKO
IPC: G03G21/14
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device which can print an image without color slippage from the first sheet of paper even when the printing is started after a long stop term or a long pause term. SOLUTION: Only in the case of the first sheet of paper, the paper is not fed simultaneously with an instruction for starting the printing. Then, the paper is fed from a pair of standby rollers when the part of a carrying belt 28 passed through a transferring and electrifying brush 38d (AA point) being at least the first brush from the most downstream arrives at a paper carrying-in part (BB point) where an attraction auxiliary roller 40 exists. In timing with it, an image forming of a recording, developing and transfer part at the most upstream is controlled. The supply interval of the second and subsequent papers is set to be a normal supply interval. When the color slippage is still caused, the AA point is set at the place of a transferring and electrifying brush 38c at the further upstream.

Title: Exhaust gas recirculation device
Inventor: MAKIBAYASHI YASUHIRO
IPC: F02M25/07
Filed: 1985-07-22
Abstract: PURPOSE:To prevent adhesion of carbon to the seat sections of a valve element and a seat, by providing an air passage for blowing out air to the seat sections to clean the latter, and by disposing a shut-off valve for opening and closing the air passage. CONSTITUTION:When the degree of vacuum introduced into a vacuum chamber 13 exceeds a pressure at which a flow control valve 9 is opened, a shut-off valve 31 is opened, and therefore air is introduced into an intake-air system 1 through a conduit 30, a passage 26, an annular groove 28 and an air passage 26 due to the negative pressure in the intake-air system. Then, air passing through the air passage 26 increases its flowing velocity since the flowing sec tional area of the passage 26 is gradually decreased, and therefore, is powerfully blown onto the seat section of a valve element 19 and a seat 21 so that carbon, etc. adhered to the sections are blown off. Further, when a predetermined time elapses after the opening of the shut-off valve 31, a delay mechanism closes the shut-off valve 31, and therefore, it is possible to prevent air in an excessive amount from mixing into recirculated exhaust gas.

Filed: 1978-12-28
Abstract: PURPOSE: To prevent the leakage of compressed air from a runner chamber at the time of operation to push down the water surface by providing a circular inclined passage on the shaft sealing apparatus and minimizing a difference between pressures forward and backward of the shaft sealing apparatus.  
     CONSTITUTION: A part of pressure water supplied to point "A" between packing 8 and shaft sleeve 9 through pressure water supply passage 12, and runs downward along the shaft sleeve 9. After flowing down to inlet point "B" on the inner circumferential surface 13a of shaftsealing disk 13, the said part of pressure water runs out towards outside in a radial direction along circular inclined flow passage 15, reaching outlet point "C". Then it flows into the back pressure chamber 13 of runner 1. During the flow from the inlet point "B" to outlet point "C" of inclined flow passage 15, the pressure increases under viscosity centrifugal action and is maintained at higher level than that of water or air in the runner back pressure chamber 13. Therefore, the leakage of compressed air blown into the runner chamber to the outside through the inclined flow passage 15 can be prevented.
