Abstract: PURPOSE:To make a titled method adaptable to diversification of product specifications by extruding preliminarily a heat-treted Al alloy shape material having a basic shape and bending the material to the shape of a required shape material according to design specifications then subjecting the material to heat treatment. CONSTITUTION:An extruded shape material 15 is preliminarily formed extrusion to a commonly usable basic shape having some angle theta in consideration for the change in the angle and is stored without subjecting the material to any heat treatment. If the prescribed angle is determined at alpha in a design specification, the material is bent to the angle alpha as shown by the virtural line at the point of the time when said angle is determined and thereafter the material is subjected to heat treatment to increase strength. The bending part is preferably formed into the thin-walled part to permit easier bending and to assure exactness in the bending position. The above-mentioned method adapts itself to diversification of product specifications and there is no need for set-up of extrusion tooling for each specification or specifying bridge members, etc. even if the specifications of the shape materials vary slightly.

Abstract: PROBLEM TO BE SOLVED: To reduce a occured pressure loss by providing a piezoelectric element with a displacement layer formed on a first electrode, a piezoelectric material layer and a second electrode laminated sequentially inside an insulating substrate and a lid joined to the surface of the insulating substrate on the side where a groove is formed. SOLUTION: A lid 14 bonded with an adhesive 12 is formed on a substrate 10 formed of a piezoelectric element. A groove 16 serving as an ink tank is formed on the substrate 10. Internal electrodes 18 laminated at a specified interval are embedded in the interior of the substrate 10 right below the groove 16. The internal electrodes 18 are laminated and each of drive layers 20 is formed between the internal electrodes 18. Thus it is possible to reduce a pressure loss generated by the driving of drive layers 20. Changing the shape of the groove 16 into a U form increases the modification level of the drive layers 20. In addition, plural piezoelectric elements are formed on a single insulating substrate and an area where the piezoelectric elements are formed is partitioned with slits. Consequently, an interference between the piezoelectric elements is inhibited to jet an ink efficiently.

Title: Charge voltage generator
Inventor: HORIIE MASANORI
IPC: B41J2/115
Filed: 1978-04-27
Abstract: PURPOSE:To obtain a charge voltage generator of fast phase retrieval speed and low cost by so constituting the same that the charge voltage at the printing and the opposite polarity voltage for phase retrieval are generated by one set of amplifier circuits without using any mechanical switch means. CONSTITUTION:When printing command signal z = 1, i.e., at the charge phase retrieval, a transistor Tr3 is ON, hence a diode D2 goes ON, resulting in that the output voltage pulse of an amplifier circuit is clamped at its bottom zero voltage level and the voltage pulse of positive polarity is applied to a charge electrode 3. When z = 0, i.e., at the print recording, Tr2 is ON and Tr3 is OFF and therefore the diode D2 goes ON, resulting in that the peak part of the output voltage pulse of the amplifier circuit is clamped at the zero voltage level, thus the negative polarity pulse is applied to the charge electrode 3. In this way, the charge voltage generator of fast phase retrieval speed and low cost may be obtained.
