Title: Ink jet printer
Inventor: NISHIZAWA ATSUSHI
IPC: B41J23/00
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To improve the degree of the freedom of a carriage during the drive of a suction pump. SOLUTION: This ink jet printer has paths R1-R9 along which an activating projection 22a, attached to a carriage movably in a direction crossing the direction of the reciprocation of the carriage, is passed, and a part 93 to be activated which faces the paths. It is equipped with a switching/holding means for switching a switch gear 73 to a suction pump drive gear 64 by being activated in response to the contact of the part 93 with the activating projection and also for holding it in the switched position. The paths have activating paths R7 and R8 for activating the switching/holding means in response to the entry of the activating projection, and nonactivating paths R1-R5 which do not activate the switching/holding means even when the activating projection enters.

Title: Exhauster
Inventor: ONO MORITOSHI
IPC: F01N1/08
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To smoothly discharge an exhaust gas and improve fuel consumption, by providing a primary exhaust passage which extends downstream of an exhaust introducing portion and has a tapered portion becoming thinner toward its end, and a secondary exhaust passage concentrically surrounding the primary exhaust passage, wherein both exhaust passages communicate with each other through a secondary exhaust inlet port located upstream of the tapered portion. SOLUTION: An exhaust gas travelling as a warhead-like travelling wave enters a front cylindrical portion 2a of a primary exhaust passage 2 through an exhaust introducing portion 1, and then, enters a rear tapered portion 2b of the primary exhaust passage 2. The exhaust gas collides with the inner wall of the tapered portion 2b, and travels against resistance toward a primary outlet port 3 located in the center having the lowest flow rate. The travelling pulsed exhaust gas is rapidly pressurized upon collision with the tapered wall, whereby the exhaust gas having a low flow rate is forced into a secondary exhaust passage 4 through a secondary exhaust inlet port 5.  Thus, the exhaust gas travelling near the inner wall of the exhaust piping, i.e., the exhaust gas that is likely to be stagnant, is quickly discharged, thereby improving intake and exhaust states of the internal combustion engine.

IPC: B01J19/20
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To provide a process for producing an aromatic carboxylic acid, especially terephthalic acid (TA) and giving TA having improved optical properties.  
     SOLUTION: A liquid containing an organic solvent, a catalyst, etc., and held in a reaction vessel 1 is circulated by an impeller 9 in a draft tube 6 and an aromatic alkyl reactant is introduced through a line 17a into the circulating liquid at the point of maximum turbulent flow to effect the quick dispersion of the reactant into the liquid. Pure oxygen or almost pure oxygen is blasted through a line 17 into the liquid at the point of maximum shear rate directly adjacent to the impeller to effect the quick dispersion of oxygen in the liquid in the form of small bubbles. The mixture of oxygen and the aromatic alkyl compound is maintained at respective specific pressure and temperature for a prescribed retention time to recover the product free from coloring impurities and obtain the objective aromatic carboxylic acid, especially terephthalic acid. The oxygen concentration in the liquid phase is maximized by the use of pure oxygen and the concentration of supplied hydrocarbon is minimized by the dilution with the content of the reaction vessel.
