Title: Method for driving ink jet head
Inventor: CHIYOU KIMEI
IPC: B41J2/015
Filed: 1991-09-05
Abstract: PURPOSE:To prevent the generation of satellites and the mixing with air bubbles by successively applying a pulse suddenly stopping the flow of the ink in a nozzle and a pulse gently returning drive voltage to base voltage so as not to generate the back flow of ink as the drive voltage pulses to a piezoelectric element. CONSTITUTION:In an on-demand type ink jet nozzle, a drive voltage pulse is applied to a piezoelectric element 3 and the strain generated accompanied by the application of said pulse is utilized to pressurize ink to inject an ink liquid droplet. In this case, an instantaneous sudden stop pulse is applied from the peak of voltage to rapidly overcome the inertia of the piezoelectric element 3 or that of the ink in an ink chamber 4 and the flow in a nozzle 5 and the injection of the ink from the orifice of the nozzle are suddenly stopped to prevent the generation of satellites. Thereafter, voltage is gently returned to the original base voltage so as not to suddenly return the deformation of the piezoelectric element 3 and the balance of the surface tension of the ink in the orifice of the nozzle 5 is held and the mixing with air bubbles due to the back flow of the ink is suppressed.

Title: Fuel feed quantity control device of internal-combustion engine
Inventor: NOMURA TOSHIO
IPC: F02M37/08
Filed: 1982-12-27
Abstract: PURPOSE:To save the power consumption and reduce noises during an idle operation by controlling the operation duty ratio of a fuel feed pump so that it is increased as the rotation speed of an internal-combustion engine is increased. CONSTITUTION:An engine pulse EP detected by an engine pulse detector 1 is fed to a one-shot multivibrator 2, and a pulse P with a constant width is outputted from here. This pulse P is fed to a motor drive circuit 3 so that the current is fed to a feed pump driving motor 4 for a fixed time. Accordingly, the current is fed to the motor 4 intermittently while the engine rotation speed is low as shown by a waveform MC, and its operation duty ratio is made low. On the other hand, when the rotation speed is increased, the duration when the current MC is cut off becomes shorter and the operation duty ratio is increased, and finally the operation becomes continuous and the operation duty ratio becomes 1.

Abstract: PURPOSE:To reduce absorption of X rays at a window, by dividing an X-ray taking out tube into small chambers, exhausting gas from each chamber, thereby reducing the pressure, which is applied on a window made of beryllium on the side of an X-ray generating chamber, and the pressure, which is applied on a mask side chamber, and achieving the thin piece of the X-ray taking out window. CONSTITUTION:An X-ray taking out tube 6 is divided into small chambers 7a...7e by partitioning walls 6a...6d forming concentric openings corresponding to the expansion of X ray 4. The pressure in an exposure chamber 5 is kept at one atm. He gas at one atm is sent into the small chamber 7e at the side of the lowest mask of the X-ray taking out tube 6 from an He-gas introducing port 8. The He gas is exhausted from the small chambers 7d, 7c, 7b and 7a through He-gas exhausting ports 9. Therefore, the small chamber 7e is kept approximately at one atm. The atmospheric pressure becomes gradually small at a pressure gradient determined by the constitution of each chamber toward the next higher small chambers. The atmospheric pressure in the small chamber 7a is fairly small. The thickness of the first X-ray taking out window 3a between the X-ray generating chamber, which is kept at a vacuum, and the small chamber 7a is made fairly thin. Meanwhile, both sides of a second X-ray taking out window 3b become one atm.

Title: Muting method of record player
Inventor: INOUE KIYOUICHI
IPC: G11B3/00
Filed: 1982-12-27
Abstract: PURPOSE:To mute assuredly the shock noises produced when the stylus tip touches the surface of a record disk by detecting first that the occurrence of tracking errors reaches the prescribed level after the driving signal is generated and releasing the muting state based on the detection signal. CONSTITUTION:When the tracking errors exceed the prescribed level set by the voltage value of a voltage source 33, a comparator 34 produces a high potential output. Then FF31 is reset and the output given from a Q output terminal is set at a low potential. At the same time, the outputs of AND gates 38 and 39 are also set at low potentials. Transistors (TR)40 and 43 are turned off, and a muting relay 41 is not energized. Then a contact 42 is switched off to release the muting state for the output of a pickup cartridge 6. When the TR40 is kept off, a tracking error detector 11 detects the occurrence of tracking errors exceeding the prescribed level. In this case, a stylus tip 19 already reaches the surface of a record disk. Thus the shock noises produced when the tip 19 touches the surface of the record disk can be muted.

Title: Production of (meth)acrylic acid ester
Inventor: OKADA SHINJI
IPC: C07C67/08
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To provide a process for producing a (meth) acrylic acid ester while suppressing the corrosion of the apparatus with a distillate containing water produced by the transesterification reaction and inhibiting the polymerization of (meth) acrylic acid contained in the distillate. SOLUTION: A water/n-hexane azeotropic mixture distilled off from a reactor 1 through a fractionation column 2 contains an acid catalyst and acrylic acid. The pH of the water layer 4b in the separator 4 is adjusted to >6.5 by adding an alkaline aqueous solution composed of 25% NaOH solution before the condensation of the distillate. The acrylic acid and the acid catalyst in the distillate is neutralized by this process to inhibit the polymerization of acrylic acid in the distillate. This process is especially effective for suppressing the polymerization of acrylic acid without adding an additional polymerization inhibitor to the water layer 4b. Since the distillate has lowered corrosiveness, a sufficient corrosion resistance can be attained even by using a general-purpose material as the material for the apparatus.

Title: Method for annealing ms-based stainless steel and cr-mo steel
Inventor: IKEDA KOICHI
IPC: C21D6/00
Filed: 1988-09-12
Abstract: PURPOSE:To effectively reduce delta-ferrite in a short time by soaking an Ms-based stainless steel and a Cr-Mo steel at a precified temp., transiently cooling the steel, then again soaking the steel at a specified temp., and annealing the steel. CONSTITUTION:The bloom or billet of an Ma-based stainless steel and a Cr-Mo steel is soaked at >=1200 deg.C preferably at about 1200-1300 deg.C. The steel is then cooled until the surface or center of the steel is cooled to <=1200 deg.C, or preferably to about 1100 deg.C. In this case, the steel is preferably cooled at a rate of >= about 10 deg.C/min. The steel is then again soaked at 1000-1200 deg.C, or preferably at about 1100 deg.C. The delta-ferrite in the steel is effectively reduced by this soaking and diffusion annealing method. When the steel is formed into pipe by the Mannesmann process, the cracking of the inner surface of the pipe due to the delta-ferrite at the center of the material is prevented.
