Patent JP-S61255866-A (JP)
Title: Liquid jet recording head
Inventor: HIRASAWA SHINICHI
IPC: B41J2/05
Filed: 1985-05-09
Abstract: PURPOSE:To make it possible to obtain sufficiently practicable life even if the part of a heat generation means has no protective film, by providing a wiring part for applying potential to the liquid in a liquid jet recording head to a substrate provided with an energy generator and electrically connecting an orifice plate to the wiring part. CONSTITUTION:An orifice plate 18 is contacted with a liquid 12 and voltage Vink is applied to the liquid 12 by a conductive material 19 and an electrode 16. If the potential of the liquid 12 is higher than that of a resistor 9, the electrochemical reaction with the resistor 9 rapidly advances and, if the potential of the resistor 9 is higher than that of the liquid 12 or there is no difference therebetween too much, a current is hard to flow and, therefore, electrochemical reaction does not almost advance. As a result, the life of the resistor 9 becomes long and, even if there is no protective film, life sufficient from a practical aspect can be obtained. Further, because the potential Vh-Vg applied to a heat generator 2 can be reduced by eliminating the protective film, the load of the heat generator 2 is reduced and service life can be prolonged still more.

Title: Manufacture of high water absorption polymer
Inventor: KURUTO DAAMEN
IPC: C08F8/14
Filed: 1988-04-22
Abstract: Highly water-absorbing polymers containing a small amount of oligomers which can be extracted with water or physiological saline solution are obtained by reacting a crosslinked carboxyl- and/or carboxylate-containing polymer, for example poly(meth)acrylic acid, first with an unsaturated hydrophobic glycidyl compound and then polymerising the reaction product. The polymerisation is advantageously carried out in the presence of a polyfunctional crosslinking agent. In this way, polymers containing less than 10 % by weight of extractable oligomers can be obtained. These polymers are used for absorption of body fluids in the hygiene sector.

Filed: 1985-05-10
Abstract: PURPOSE:To obtain the circuit protecting device without the necessity to provide the micro switch by specifying the terminal contacting sequence when the cartridge substrate is inserted to the connector at the main body side. CONSTITUTION:When a cartridge substrate 11 is inserted into a main body connector 10, first, a protecting signal terminal 15 and an earth terminal 17 are contacted to terminals 20 and 22. The terminals 20 and 22 are electrically connected, and therefore, the terminal 15 comes to be the grounding electric potential. For such a reason, an electric power source interrupting part 12 comes to be off and the main body electric power source output comes to be off. Further, when the substrate 11 is inserted, a protecting signal terminal 16 is contacted to a terminal 21. Since terminals 21 and 22 are electrically connected, the terminal 16 is grounded. For such a reason, the electric power source interrupting part 12 comes to be on and the voltage of an electric power source input terminal 13 is outputted to the output terminal. Thus, the circuit protecting device without the necessity to provide the micro switch can be obtained.
