Title: Liquid jetting method for liquid jet recording head and recorder
Inventor: TANETANI YOICHI
IPC: B41J2/205
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To obtain a high quality print where the hitting position is not shifted regardless of the dot diameter by employing drive conditions within such range as the drive timing difference, i.e., the drop jetting speed, is substantially constant and the quantity of drop varies when a drop is jetted by driving a plurality of electrothermal converters sequentially. SOLUTION: A plurality of channels 1 are formed while being sectioned by a channel wall 6 and first and second heaters 5, 4 for heating any one or both channels are disposed sequentially in each channel 1 in the flow direction. When the difference of timing for applying a drive pulse to the first and second heaters 5, 4 is increased, the delivery is decreased gradually along with the delivery rate and a minimum delivery is reached at a specified timing difference. Subsequently, the delivery is increased again but the delivery rate is kept in a substantially constant region (region b). Minimum delivery can be realized using the first heater 5 solely and when the drive timing of the second heater 5 is set in the region b, the delivery can be varied while keeping a constant delivery rate.

Abstract: PROBLEM TO BE SOLVED: To additionally lessen the change in the properties of blood components and the stimulus to the blood components by suppressing the remaining of the chemical species subjected to an oxidation effect induced by being subjected to a radiation treatment into a blood treating membrane. SOLUTION: This blood treating membrane is a blood treating membrane having reducing power on at least the membrane surface of the blood treating membrane subjected to the radiation treatment and preferably the reducing power is <=20 in the (a*) value obtd. by an NR test.

Inventor: FUJITA KIYOSHI
IPC: A47H23/04
Filed: 1990-08-03
Abstract: PURPOSE:To hide a supporting rod inserted through holes for improving outlook by providing a bending margin upward of the holes and bending and hanging down the bending margin forward. CONSTITUTION:A plurality of holes 10 are provided in a lateral line with an equal interval between each other at a top end part of a curtain, and a bending margin 30 which bends forward is provided upward of the holes 10. Accordingly, when a supporting rod 20 is inserted through the holes 10 to hang the curtain, and the bending margin 30 is bent forward and hung down, the supporting rod 20 is hidden by the bending margin 30. If the holes 10 are not arranged at equal intervals, when the supporting rod 20 is inserted through the holes 10, the supporting rod 20 runs longer on a rear side than on a frontside of the curtain, whereby the total length on the frontside by which the supporting rod runs can be reduced. That is, the length by which the supporting rod 20 is exposed is minimized when viewed from the frontside. This is effective with a curtain made of lace cloth which permits seeing through.

Abstract: PURPOSE:To enable the diazotization of an aromatic amine, advantageously from the viewpoint of quality and cost, by controlling the amount and rate of addition of a nitrite according to the concentration of the nitrite determined from the heat of reaction of the nitrite and the compound to be reacted with the nitrite. CONSTITUTION:An aromatic amine is diazotized by reacting with an inorganic nitrite under acidic condition in an aqueous system. A specimen collected by a metering pump 1 is mixed with air sent by a metering pump 2, the temperature of the mixture is stabilized by a heat-exchanger 5 and the specimen is mixed and reacted (7) with a compound (e.g. sulfamic acid) reactive with the nitrite and supplied by a metering pump 3 through the heat-exchanger 5. The temperatures before and after the reaction are measured by temperature sensors 6, 8, the temperature difference (corresponding to the concentration of the nitrite) is converted to an electric signal with a temperature difference converter 9 and the amount and/or rate of addition of the nitrite are controlled by an automatic controller based on the signal. The excessive nitrite used in the reaction can be decreased by this process.
