Title: Joined material of zro2 and metal and its production
Inventor: KITA HIDENORI
IPC: B23K20/00
Filed: 1993-02-12
Abstract: PURPOSE:To obtain a joined ZrO2/metal material having high bonding strength and improved reliability of the bonding strength and to provide a process for the production of the joined material. CONSTITUTION:A layer of a non-oxide is present at the interface of ZrO2 and a metal and the metal is bonded to ZrO2 with a solder material interposing the non-oxide ceramic layer. Since the layer of the non-oxide has high covalent bond nature, it has strong bonding force. The penetration of oxygen in ZrO2 to the solder material is inhibited by the oxygen-shielding layer formed by the non-oxide layer to suppress the oxidative deterioration of the solder material and the lowering of the bonding strength. A joined material of ZrO2 and a metal having high strength can be produced by this process.

Title: Thundercloud detecting system
Inventor: FURUKAWA TATSUMI
IPC: G01W1/16
Filed: 1981-03-31
Abstract: PURPOSE:To detect thundercloud correctly, by measuring an electric field in the air by using an electric field meter and deciding whether the situation of its variation coincides with the previously set conditions or not. CONSTITUTION:Holes 8 are provided on the upper surface of a case 7 and an electric field meter is constituted in the case 7 by disposing a collector 10 to be rotated by a motor 9. When the collector 10 made of a metallic plate is rotated and faces to the air through the holes 8, it performs current collection and when it is cut off from the air, it discharges electricity and detects an electric field intensity in the air as alternating signals. By such method, the presence or absence of an electric field having intensity stronger than the prescribed value, the time or ratio which said field intensity occupies in the fixed time and the frequency of polarity variation of electric field value are calculated, and it is decided whether the thundercloud exists or not. The detection of thundercloud is more exactly performed in comparison with the measurement by a radar because thundercloud before thunder rolls is detected through the character of its electrification.

Abstract: PROBLEM TO BE SOLVED: To restrain warp and degradation which are caused by a stress remaining in an insulating layer when the insulating layer is formed by a method wherein a stress relaxation part which relaxes the stress remaining in the insulating layer is formed in the insulating layer. SOLUTION: A semiconductor substrate 2 which constitutes an SOI substrate 1 is composed of a P<-> type silicon single crystal, and a semiconductor layer 4 is formed on it via an insulating layer. Three insulating layers 3a to 3c are laminated sequentially from the lower part. The substrate 2 ensures the strength of the substrate, and the upper and lower insulating layers 3a to 3c ensure the bonding force of the substrate 2 to the semiconductor layer 4. The intermediate insulating layer (as a stress relaxation part) 3b is a member which relaxes a stress remaining in the insulating layers 3a, 3c, and it contains a stress in a direction opposite to the residual stress in the insulating layers 3a, 3c.  By this structure, the stress in the insulating layers 3a, 3c is offset by the stress in the insulating layer 3b, it is possible to restrain the warp of the SOI substrate 1 and the quality degradation of the semiconductor layer 4.
