Title: Electron emitting element and manufacture of it
Inventor: KANEKO AKIRA
IPC: H01J9/02
Filed: 1989-05-19
Abstract: PURPOSE:To enhance the charged voltage between a negative electrode material for an electron emitting element and an electrode for electron drawout by deciding the foremost shape of the negative electrode material solely depending upon the film thickness, minimizing it for easier concentration of the electric field, and thereby providing spatial gaps and an insulative layer between the negative electrode material and the electrode for electron drawout. CONSTITUTION:An insulative substance layer 2 consisting of Al2O3, SiO2, Si3N4, etc., is furnished on one side of an electric insulative base board 1, and a negative electrode material 3 consisting of W, Mo, Ta, TiC, DiC, ZrC, etc., is provided in the center of this insulative substance layer 2, wherein one of them is protruded a certain amount from the recess formed in the insulative substance layer 2 in such a way that the protruded surface will be flush with the base board 1. An electron drawout electrode 4 consisting of W, Mo, Ta, etc., is provided on the recessed side of this insulative substance layer 2 of base board 1. To prepare an array of electron emitting elements, a conductive layer 5 insulated electrically from the negative electrode material 3 is provided according to necessity on that side of the base board 1 which is situated oppositely to the electron drawout electrode 4, and the foremost shape of the insulative material 3 is determined only depending upon the film thickness.

Title: Ink jet recording device
Inventor: ODA HAJIME
IPC: B41J2/175
Filed: 1990-05-16
Abstract: PURPOSE:To allow air accumulated in an ink chamber to be released without breaking a meniscus formed at an ink discharge orifice by discharging an unnecessary air which is compressed in the ink chamber by opening an air discharge path, if a large amount of air is accumulated in the ink chamber, and preventing a rapid discharge of air using a device to give resistance to the path. CONSTITUTION:If an unnecessary air is increasingly accumulated in an ink chamber 6, a resistance variation between two electrodes 20,21 is detected, a solenoid valve 19 is activated from a closed state to an open state based on the detection signal. Subsequently, unnecessary air compressed in the ink chamber 6 passes through an air discharge path 17 and is discharged to an atmosphere running through an orifice 18 at the outer end of the path 17. Then when the air is discharged from the ink chamber 6, the air of the ink chamber 6 is prevented from becoming emptied rapidly, resulting in a sudden drop in the internal pressure of the ink chamber 6. Thus an ink meniscus formed at an ink discharge orifice 7 can be prevented from becoming broken due to the unbalanced pressure of the meniscus.

Title: Human body detecting device and air-conditioning system equipped with human body detecting device
Inventor: SAGARA MASASHI
IPC: G01S17/50
Filed: 1989-05-17
Abstract: PURPOSE:To prevent the occurrence of a false detection that a human body moves, even if another human body traverses in front or in the rear of the human body being followed currently, by outputting a man movement signal only when an input value from a light- emitting means is a second set value or below being lower by a prescribed value than a first set value while a man detection signal is outputted. CONSTITUTION:When a human body is present in the front, infrared rays emitted from a pair of light-emitting means H1 and H2 are reflected diffusedly by the clothes of the human body. Then either of input values of the infrared rays sensed by a light-sensing element J is a first set value or above and a man detection signal is outputted by a man detecting means 101. The input values of the infrared rays are compared by a comparing means 102 with a second set value being lower by a prescribed value than the first set value, and only when one of the input values turns lower than the second set value, it is determined by a man movement determining means 103 that the human body moves, the man detection signal being outputted. Even if another human body traverses in front or in the rear of the human body being followed currently, the input values do not turn to be the second set value or below due to the reflection of the infrared rays from the human body being followed, so far as this human body stands still, and thus a false determination that the human body moves though it does not move actually, is prevented.

IPC: H01L21/768
Filed: 1983-07-15
Abstract: PURPOSE:To make the thickness of an inter-layer insulating film formed on an extended wire the same as that of a wiring section, and to enable flat element structure, etc. by forming the comparatively narrow extended wire outside a bonding pad and bringing each conductive layer constituting the pad into contact in the extended wire section. CONSTITUTION:Aluminum is evaporated on the surface of a semiconductor substrate 1, and the surface is coated with a mask, to which a first layer wiring pattern in an internal circuit is formed, and etched, thus simultaneously forming a first layer wiring and a first layer conductive layer 3a. A first inter-layer insulating film 2a is shaped on the wiring and conductive layer through deposition technique for SiO2 by sputtering. Consequently, an SiO2 film is formed thinly on a narrow aluminum wiring, and the SiO2 film is formed on other sections comparatively thickly, thus shaping the surface of the first inter-layer insulating film 2a approximately smoothly as a whole. Accordingly, the width of a second layer aluminum wiring formed through masking and etching after a contact hole is formed to the first inter-layer insulating film 2a and aluminum is evaporated on the contact hole can be made thinner than the case there is irregular sections.
