Title: Carriage drive device of serial recorder
Inventor: IGAKI MASAHIKO
IPC: B41J19/30
Filed: 1989-07-07
Abstract: PURPOSE:To enable a gap between a sheet surface and a recording head to be kept constant irrespective of variation in thickness of the sheet by a method wherein a drive surface of an elastic material wherein a progressive wave is oscillate is pushed on a feed roller via a sheet, and a carriage is driven. CONSTITUTION:A comb teeth like part 9a of which a surface is composed of a plurality of vibrating pieces is formed in a down side straight line part 91 of an elastic material 9, and the comb teeth like part 9a comes in pressure contact with a paper feed rooler 8 via a printing sheet 15. A piezoelectric element group 10A and a piezoelectric element group 10B which are composed of a plurality of piezoelectric elements of different polarities are fixed to a surface of an upper side straight line part 90. A thrust in the reverse direction to the progressive wave acts on a contact surface of the comb teeth like part 9a of the elastic material 9 with the printing sheet 15, and a carriage 2 is driven along a generatrix direction of the paper feed roller 8. Further, since a surface of an ink discharge opening 7a is located inside a specific distance apart from the surface of the elastic material 9, even though a thickness of the printing sheet 15 varies, a gap between a printing surface of the printing sheet 15 and the surface of the ink discharge opening 7a can be kept constant in the generatrix direction of the paper feed roller 8.

Abstract: PROBLEM TO BE SOLVED: To provide a polyaniline composition with high chemical stability and high industrial application value for a lithium secondary battery by uniting an aniline type compound with an electric collector substance by chemical oxidation polymerization in the presence of the electric collector substance. SOLUTION: An aqueous solution is so produced as to adjust the aniline concentration to be 10vol.% in the aqueous solution, an acid such as hydrochloric acid, perchloric acid, ethane disulfonic acid, etc., is added as to adjust the acidic group equal to or more than amino group by mole, a carbon material is further added to the resultant solution in 5-10wt.% to aniline, and the resultant solution is cooled to 0 deg.C or lower. An aqueous solution of an oxidizer such as ammonium persulfate, hydrogen peroxide, etc., in 1.0-2.0 equivalent mole concentration is slowly titrated to the obtained aniline solution. After that, reaction is carried out about at 0 deg.C for 2-24 hours, the produced products are separated, washed, and dried to obtain polyaniline composition.  In the case the obtained composition is used as a cathode material for a lithium secondary battery, polyaniline separation from the collector material scarcely occurs and ohmic resistance can be lowered.

IPC: F01N9/00
Filed: 1991-07-17
Abstract: PURPOSE:To easily diagnose the failure of a secondary air feed device and avoid the inconvenience by an excessive or deficient supply of secondary air. CONSTITUTION:When the feedback control of air-fuel ratio of the mixed air sucked into an engine 1 is cramped, it is judged whether the ratio is contained in a determined diagnostic operating area or not (S7). When it is within the diagnostic operation area, the supply 21 of secondary air is forcedly interrupted and continued (S10), and the change of the detection result by an oxygen sensor 16 provided on the lower stream side from the feed position of secondary air is judged (S11). When the oxygen concentration in exhaust air does not show the corresponding change at the time of interrupting and continuing the supply of secondary air, a failure of secondary air feed devices 18-23 is diagnosed.

Abstract: PURPOSE: To obtain an optical isolator which has 100% transmittance in the forward direction, by putting the taper-shaped double refraction materials at the  front and rear sides of a Faraday rotor.  
     CONSTITUTION: Taper-shaped double refraction materials 11 and 11' are put at both sides of a 45° Faraday rotor 12 in such a way that the optical axis of the 2nd taper-shaped polarization separating element 11' is turned by 45° in the direction of the beam to the optical axis of the 1st taper-shaped polarization separating element 11. The incident beams are separated into the normal beams and abnormal beams by the element 11 to be made incident to a fixed 45° Faraday rotor 12. The normal and abnormal beams with their polarizing surface turned by 45° are radiated in the form of the parallel beams in accordance with the normal and abnormal beams within the element 11' to be focused by a lens (D) to an optical fiber 4. The beam traveling in the opposite direction do not go into an optical fiber 1 since their radiation direction is difference from the incident beams.

Filed: 1991-07-17
Abstract: PURPOSE:To prevent the protuberance of the shoulder section of a stripe groove, and to obviate the generation of heat deterioration even at the time of high output operation by forming a stepped section to the stripe groove. CONSTITUTION:A striped groove 3 reaching up to one conductivity type substrate 1 is formed to the opposite conductivity type block layer 2 laminated on the substrate 1. The upper section of the block layer 2 including the inside of the stripe groove 3 is coated thinly with a resist in an extent that the shoulder section of the stripe groove is broken and the block layer 2 is exposed, and the block layer exposed is etched. Consequently, the shoulder section of the stripe groove 3 is removed, and the stripe groove 3 is brought to a stepped state. A p-type clad layer 4, an active layer 5, an n-type clad layer 6 and a cap layer 7 are formed by liquid growth successively on the block layer 2, to which the stripe groove 3 having a stepped-shape is formed. Lastly, an n-type electrode 8 is formed onto the cap layer 7 and a p-type electrode 9 onto the rear of the substrate 1 respectively. Accordingly, the heat deterioration of an element is inhibited, thus lengthening the lifetime of a semiconductor laser.

CONSTITUTION:Coolant gas is fed under high pressure into an intake chamber 9 upon large cooling load in the room, but is fed under low pressure in the intake chamber 9 upon cooling load being reduced. A spool valve 26 closes a relief valve 27a upon large cooling load, since the pressure differential between the intake pressure and the intermediate pressure in the vicinity of a by-pass  port 21 within a compression chamber 6 is increased. Meanwhile, the spool 26  opens the relief valve 27a when cooling load in the chamber is decreased. With  this arrangement, the compression volume of coolant gas in the compression  chamber 6 is automatically controlled in accordance with cooling load.
