Abstract: PURPOSE:To make possible the high-density compaction of nozzles with increased reliability and the manufacture thereof without providing a large-size printing head by arranging an individual electrode and an opposite electrode which are connected to a heat generating resistor provided on one surface in an ink flow path, at least on two surfaces. CONSTITUTION:A thermal resistor 3, an individual electrode 4 and an opposite electrode 5 are patterned on an orifice plate substrate 12 such as of glass, then a protection layer 13 such as of silicon is patterned on the whole thermal resistor 3 and individual electrode 4 and part of the opposite electrode. After this, photosensitive resin 14 is applied and a wall on the side of an orifice plate 15 is formed by etching. Next, a metal layer for electrode formation such as aluminum is applied by vapor deposition method to form the opposite electrode 5, then a protection layer 13 such as of silicon is laminated to manufacture an orifice plate 1. The high-density compaction of nozzles is ensured only by connecting wire to either one of the individual electrode or the opposite electrode on a single surface. In addition, no wire is routed outside of the printing head, so that the printing heads can be joined together to extend the whole head assembly in length easily.

Title: Ceramic wiring board with projecting through-holes
Inventor: ISHIHARA SHOSAKU
IPC: H05K3/46
Filed: 1991-09-30
Abstract: PURPOSE:To allow the ceramic section not to be exposed even when the conductor metal of through-hole sections is exposed on the grinding surface during grinding for glazing by forming all through-holes so as to project from the surface of ceramic board when firing them on the exposed surface of the ceramic wiring board. CONSTITUTION:All through-holes 1 on the exposed surface where a ceramic wiring board is fired are formed so as to project from the surface of board ceramic 4. The contraction amount of conductor paste during firing is controlled to regulate the projection amount by adjusting the grain size of metallic powder of the conductor paste to be filled in the through-holes 1 of which green sheet becomes front/back face when piling up layers. Therefore, when the contraction ratio of the conductor paste is smaller than that of the green sheet, the through- holes 1 are formed to project from the surface 4 corresponding to the difference of contraction ratio. Furthermore, even when the conductor metal of through- hole section is exposed on the grinding surface during grinding for glazing treatment, a ceramic section 2 is not exposed.

IPC: C02F3/06
Filed: 1990-09-20
Abstract: PURPOSE:To permit an automatic adjustment of the distance of a water head between the water level on the outlet side of filter water flow for determining the amt. of back washing water and a back washing water discharge opening according to a change of season (temp. change) by freely controlling the height of a discharge pipe in response to temp. changes by the spring made of the shape memory alloy freely expansible and contractible by temp. changes. CONSTITUTION:Since a discharge pipe 10 vertically movable by the spring 11 made of a shape memory alloy is used in a back washing flow amt. adjusting device, the pipe 10 in a storage tank 14 is located in a higher position than at ordinary times when the water temp. is high in summer, the water head between the height of a filter water discharge pipe and a back washing water discharge opening 4 becomes large, the water level of the other filter tanks for supplying the back washing water becomes high in response thereto and the amt. of back washing water flowing backward in the filter tank upon cleaning is increased in comparison with that at ordinary times. On the other hand, when the water temp. is low in winter, the aforesaid head becomes small, the water level of the other filter tank for supplying the back washing water becomes low in response thereto and the amt. of back washing water flowing backward in the water tank upon cleaning is decreased in comparison with that at ordinary times. In this way the filter tank can be cleaned automatically, with a high degree of efficiency.

Abstract: PURPOSE:To prevent an effect by a change in threshold voltage at low-voltage driving and stabilize circuit operation, by changing a threshold voltage of a first inverter in accordance with an MOS transistor in an electronic switch and compensating a delay in writing time caused by a voltage change corresponding to the threshold voltage. CONSTITUTION:In a semiconductor device, a signal holding means 3 for holding a signal from a switch means 2 includes a p-channel transistor P1 and an n- channel transistor N1. The p-channel transistor P1 has a gate length Lp and a gate width Wp while the n-channel transistor N1 has a gate length Ln and a gate width Wn. Then, an expression I is satisfied, wherein BP and BN are current-drive performance in the transistors P1 and N1, VDD is a high power- supply voltage, and Vth is a threshold voltage. Since the threshold level is changed from a conventional level VDD/2 to (VDD-Vth)/2, a delay time (th) caused by a loss in voltage corresponding to the threshold voltage can be compensated. Consequently, an output signal during L to H writing time is provided to a next-stage circuit without delay, and stable operation is ensured.
