Abstract: PURPOSE:To improve a mass productivity and enhance a recording quality in an ink jet recording head consisting of a substrate provided with an element generating an energy used for an ink delivery, a top plate adhering to the substrate to form a liquid path, and a delivery port forming member further bonded thereto. CONSTITUTION:A substrate 1 as an adhering object, a top plate 3, and a delivery port forming member 4 are loaded on an inclined mount 9.

Title: Semiconductor memory device
Inventor: INOUE YOSHINAGA
IPC: G11C29/56
Filed: 1990-01-11
Abstract: PURPOSE:To simplify the margin check of the sensitivity of a preamplifier and to shorten a testing time by providing a circuit which makes a data bus line unbalanced on an accelerating testing mode. CONSTITUTION:On an accelerating testing mode, for inputs TEa and TEb, one becomes 'H' and the other becomes 'L'. When the TEa is the 'H', the electric potential of a data bus line DB1 is determined by the ratio of the capacity of MOSFETs n2 and n4. Then, data bus lines DB1 and DB2 become unbalanced. The electric potential difference of the DB1 and the DB2 becomes small and a malfunction occurs in a preamplifier of which sensitivity is low. Accordingly, a failure condition of which a margin is small can be detected.

When the operator exists in the front surface side of the console 1a, such a condition is detected by the sensor and a signal to show the existence of the operator is sent from a controller, which is not shown in a figure, provided in the equipment 1. Then, the luminance of the CRT 2 is held constant. Next, when the operator is separated from the console 1a, such a condition is detected by the sensor 3 and samely, the signal to show the absence of the operator is outputted from the controller. Then, the luminance of the CRT 2 is lowered to the prescribed luminance. Thus, the luminance is increased or decreased according to the presence and absence of the operator in front of the console 1a. Then, the CRT is prevented from being burned and energy consumption is reduced.

Title: Mold for casting metal
Inventor: YUSHIMO KENKICHI
IPC: B22C9/06
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To effectively heat the surface of molten metal with small heat loss and to stable producy an ingot, etc., of metallic silicon by dividing a mold into a bottom part and side wall parts and using a water-cooled metallic jacket at the bottom part and a graphite plate at the side wall parts. SOLUTION: In the casting of a high m.p. metal or the metallic silicon, the copper-made water-cooled jacket 2 is arranged at the bottom part of the mold 1 and the graphite plates 3 is arranged at the side walls, and they are assembled with each other by screws, etc. Since the mold 1 is formed into the assemble type, the service life of the mold can be prolonged by changing the damage part even if the damage or the deterioration is caused by repeatedly using. Since, the graphite plate 3 at the side walls is low in heat conductivity, it is prevented that the heat from a heating source arranged upward at the time of using the mold 1 is lost from the side walls. Further, the graphite plate 3 at the side walls divided into two layers is used to form the heat insulating layer of the air between two layers, and this, high heat insulating effect is obtd. and the heat loss can be reduced.
