Thus, in the current-carrying process and the activation process, even if dispersions or failures of the electric characteristic of each electron emission element in an electron source occurs, they are restricted only to a loss of an electron source base.  In addition, by providing the sealing process in a vacuum whose oxygen partial pressure is not more than 1×10-3 Pa and water partial pressure is not more than 2×10-3 Pa, occurrence of failure such as degradation of the electric characteristic of the electron emission element can be prevented.

Title: Substrate susceptor for epitaxial growth
Inventor: NISHIMURA TAKAYUKI
IPC: C30B29/42
Filed: 1990-11-16
Abstract: PURPOSE:To decrease the generation of cracks from the peripheral part of a substrate for epitaxial growth and to improve the yield of substrate formation by forming a groove in the position corresponding to the peripheral part of the substrate to prevent the contact of the peripheral edge with the substrate. CONSTITUTION:A recessed part 4a is formed atop the substrate susceptor 4 so as to allow the Si substrate 1 to be housed therein and the groove 4b is formed at this peripheral part. The groove 4b exists below the peripheral edge of the substrate 1 to prevent the contact of the peripheral edge of the substrate 1 with the susceptor 4 when the substrate 1 is held by the susceptor 4. The substrate 1 is held on this susceptor 4 and GaAs is epitaxially grown on the substrate 1. The temp. is high and uniform in the central part of the substrate 1 in contact with the susceptor 4 in this way and the temp. is lower than in the central part and is unstable at the peripheral part of the substrate 1 which does not come into contact with the susceptor 4. Consequently, the good epitaxial layer is grown in the central part and the layer which is thinner in the central part and has poor crystallinity is grown at the peripheral part. The cracks to be generated at the peripheral part are thereby decreased.

Title: Nondestructive inspecting method for adhered structure
Inventor: YONEDA SHUJI
IPC: G01N25/18
Filed: 1989-11-30
Abstract: PURPOSE:To enable short-time, efficient processing and to obtain the inspecting method with high accuracy by heating and exposing the adhered structure to the atmosphere and discriminating the distribution of surface temperature generated owing to a difference in heat conduction varying with an adhesion state in an infrared-ray image. CONSTITUTION:A honeycomb sandwich panel 6 where an optical solar reflector(OSR) is stuck is heated by a heating block 9 for heating and setting an adhesive and exposed to the atmosphere while heated to uniform temperature. An infrared image pickup camera 7 is positioned above the honeycomb sandwich panel 6 where the OSR is stuck and the whole honeycomb sandwich panel 6 is put in the visual field range 8. At a defect in the adhesion part of the adhered structure, the part is cooled by the atmosphere from the surface and heat is hardly conducted from inside, so the temperature becomes lower than that of the normally adhered part and the defect appears as a spot in the infrared-ray image. For the purpose, the spot appearing in the infrared-ray image is observed to easily decide the defect of the adhesion part.

Title: Ultrasonic probe
Inventor: YOSHIDA YOJI
IPC: G01N29/24
Filed: 1987-12-11
Abstract: PURPOSE:To obtain high resolution by varying the acoustic impedance in and the ultrasonic wave attenuation rate of a damper with which an ultrasonic wave vibrator is backed. CONSTITUTION:The damper 1 is formed by mixing powdery tungsten with an epoxy filler, stirring them strongly to form air bubbles therein, and depositing the powder 3 on the side of the vibrator 4 by a centrifugal separator, etc., while dispersing the air bubbles to the opposite side from the vibrator. Then when an ultrasonic wave beam 6 is propagated from the vibrator 6 to a body 5 to be inspected, the acoustic impedance is increased by the powder 3 nearby the vibrator 4, so the ultrasonic wave is propagated efficiently and the ultrasonic wave which is propagated into the damper 1 is scattered by the air bubbles 2 to suppress a reflection echo from an end surface. Thus, the high resolution is obtained.

Title: Solid-state infrared image sensor
Inventor: YUYA NAOKI
IPC: H01L27/146
Filed: 1990-11-16
Abstract: PURPOSE:To facilitate the sensitivity control of an image sensor by providing slits in a metal electrode forming the Schottky junction of a photodetector so that the insensitive area around the individual slits may vary depending on the voltage applied to a reflecting film of aluminum. CONSTITUTION:A schottky diode has a metal electrode 2 as a photoelectric layer with slits 31. The metal electrode is insensitive to light at the slits where inversion to n-type occurs by application of a voltage to a reflective aluminum layer 11. The inversion area spreads as the applied voltage increases; that is, the insensitive area increases. Since the insensitive area varies with the applied voltage, sensitivity can be easily controlled according to the amount of light incident to the device.

Title: Thermal recording apparatus
Inventor: MINOWA TAKEHIKO
IPC: B41J2/355
Filed: 1986-12-26
Abstract: PURPOSE:To obtain a recording image having high resolving power not affected by a printing speed, by controlling printing history at every dot on the basis of the printing history period from the printing of the previous time to the next printing and controlling a printing pulse width corresponding to said printing history period. CONSTITUTION:When a printing pulse having a certain width is applied to the heat generating resistor 102 of a thermal recording head, the temp. of the heat generating resistor 102 rises and, when the printing pulse is cut off the temp. of the heat generating resistor 102 falls according to an approximately determinable exponential function characteristic. Therefore, when said exponential function can be calculated, the printing history (heat accumulation temp.) of each beat generating resistor 102 can be controlled on the basis of the time (printing history period) from the time immediately after printing at every heat generating resistor 102 (dot) to the next printing. By this method, the width of the printing pulse to be applied to said heat generating resistor 102 is selectively determined so as to uniformize the heat accumulation temp. of each heat generating resistor 102.
