Title: Soundproofing structure for compressor
Inventor: IMASU KENICHIROU
IPC: F04B39/12
Filed: 1981-09-04
Abstract: PURPOSE:To improve a soundproofing effect by a method wherein the compressor is accommodated in the case of a plastic series and the inner space of the  case is evacuated. CONSTITUTION:The case 9 accommodating the compressor 1 is made of a material of plastics series and the space 10 between the compressor 1 and the case 9 of plastics is evacuated. According to this constitution, noises from the compressor 1 and the surface of the pipe are not propagated to the case 9. However, vibration is propagated to the case 9 through the compressor 1, anti-vibration rubbers 12 and, further, to a discharging pipe 2, a suction pipe 6 and capillary tubes 8 for injection even though they are shaped into anti-vibration configurations. However, the case 9 is made of a material of plastics, therefore, the vibration restraining effect thereof is high and it will never become the source of sound easily. Furthermore, the case 9 is prevented from vibration by legs 13 and the anti-vibration rubbers 14, therefore, the vibration transmitted to the base plate 15 is very little.

Title: Method and device for printing image can be read by magnetic image characteristic recognistion device
Inventor: SUTEIIBUN EFU PONDO
IPC: B41M5/00
Filed: 1993-06-11
Abstract: PURPOSE: To achieve magnetic image characteristic recognition printing by a thermal ink jet printer by drying the printing data image on a recording medium under the influence of an external magnetic field so that magnetic particles in the liquid ink of a printing image are oriented toward a magnetic field and permanently preserved in the printing image at the time of drying of the printing data image. CONSTITUTION: Since a magnetic pole is arranged so that the line 32 of magnetic force from a magnet 30 passes through a printing area, the liquid droplet 28 colliding with a recording medium receives the influence of the line of magnetic foce immediately to execute the re-orientation of magnetic particles in a liquid medium. Since the printed liquid droplet is dried before the line of magnetic force is released, the magnetic re-orientation of magnetic particles in ink is permanently preserved in the dried liquid droplet. That is, the line of magnetic force generated in the electromagnet re-orients magnetic pigment or particles 34 after several msec.  Since the printed liquid droplet is dried under the influence of the line 32 of magnetic force before the recording medium is stepped to receive data of printing width, the re-oriented magnetic pigment or particles are permanently preserved in the dried liquid droplet 29.

CONSTITUTION:If the sheet is a coating sheet or an OHP film, or when the frictional coefficient muf between a belt 5g and the sheet 2 and the frictional coefficient mur between a separating belt 7g and the sheet 2 come to have such a relationship as muf<mur so that he feed of the sheet downstream of a separating and transferring section A becomes impossible, and when the leading end of the sheet 2 is not transferred to a second sensor 18 within three seconds after it passing through a first sensor 17, a control section 19 receiving a signal from the second sensor 18 which has detected the above-mentioned fact energizes a solenoid 18 for about two seconds so that a pick-up roller 2 drops again onto the sheet 2. At this time a force for transferring the sheet 2 is obtained also by the transferring force of the roller 4 in addition with the transferring force of the transfer belt 5g. Accordingly, even if the relationship of the frictional coefficients is such as muf<mur, the sheet 2 may be transferred to a downstream reading section B.
