Title: Ink jet head of ink jet recorder
Inventor: HAYASHI HIROKAWA
IPC: B41J2/175
Filed: 1978-06-07
Abstract: PURPOSE:To prevent injection defect of ink liquid by so constituting the ink jet head that the entry of air bubbles into injection nozzle is prevented by heating the ink liquid having flowed into the ink jet head thereby surely expelling the air bubbles in the ink liquid. CONSTITUTION:Ink liquid having flowed into an ink liquid distributing chamber 2 through ink liquid influent port 9 is first heated by a heating element l4 at the time when it flows in the inside of the ink influent chamber 2a. As a result, the air bubbles having mixed in the ink liquid grow owing to thermal expansion, are enlarged, rise rapidly within the influent chamber 2a, arrive at the air layer in the upper part of the distributing chamber 2 and are exhausted to the outside through an exhaust hole 12. Since the ink liquid reaches the upper part of the intermediate chamber 2b from the influent chamber 2a and flows toward the lower part of the intermediate chamber 2b therefrom, the influx of the air bubbles into the effluent chamber 2c does not occur. In this way, the injection defect of the ink liquid owing to the mixed presence of the air bubbles may be prevented.

Title: Method of shot-peening steel plate
Inventor: OOTA KUNIO
IPC: B24C1/00
Filed: 1982-04-23
Abstract: PURPOSE:To greatly enhance the efficiency of grinding by centrifugal shot projection, by centrifugally projecting shots of 0.10-0.25mm. in grain size from a position of 900mm. or less in projection distance to peel scale off a steel plate. CONSTITUTION:The efficiency of grinding is independent of the distance of projection and maximum at 0.18mm. in the grain size of steel shots. The maximum efficiency of grinding is about 20% higher than that by a conventional method with steel shots of 0.30mm. or more in grain size. The use of the steel shots at the lower grain size of 0.10-0.25mm. leads to the economization of energy. The efficiency of grinding is high and nearly constant independently of the projection distance when it is 900mm. or less. The present method of shot-peening with steel shots of small grain size at a projection distance of 900mm. or less results in bringing a high grinding efficiency for an iron plate and economizing energy.
