Title: Chip type electronic parts
Inventor: ONISHI MASAAKI
IPC: H03H9/02
Filed: 1990-04-05
Abstract: PURPOSE:To prevent damage for electronic part element even when it is dropped down by any cause by making one end part of a cylindrical object heavier than the other end part so that the electronic part element can be dropped down in a vertical state ti make the lengthwise direction almost coincident with the falling direction, CONSTITUTION:For a metal cap 11, a material with specific gravity larger than that of a metal cap 10 is adopted and namely, the weight of one metal cap 11 is heavier than that of the other cap 10 although the dimension is same. Therefore, when dropping a piezoelectric part 1' down, it is dropped down so that the lengthwise direction of a piezoelectric resonator 3 can be almost coincident with the falling direction, namely, almost vertically to the surface of a floor. Namely, since one end part of the cylindrical object is made heavier than the other end part, when the electronic part 1' falls down, it collides the floor surface in the vertical state of directing one heavier end part of the cylindrical object 2 downside, and accordingly, the impulse of the drop is operated in the lengthwise direction of the electronic part element 3. Thus, in comparison with the case of drop in a horizontal state, the impulse can be relaxed and the damage can be prevented.

IPC: G01M3/04
Filed: 1986-04-23
Abstract: PURPOSE:To certainly detect an article to be detected by preventing the penetration of foreign matter such as refuse in a detector, by mounting a bent passage on a foreign matter penetrating route on the upstream side area thereof from the detection end of the detector. CONSTITUTION:When it is assumed that a falling gradient is provided to a detector in an X-direction and welding refuse 51 is present on the bottom part of a cover sheet 42 to be approaching the detector by vibration, said welding refuse 51 is taken in a U-shaped flow passage 28 from a U-shaped passage inlet 28a and can not enter the detection end 1a. Next, if it is considered that sodium 53 leaks from a crack 52, leaked sodium being a substance to be detected advances to the X-direction to be taken in the U-shaped flow passage 28 like the welding refuse being a foreign matter but gradually accumulated to be flooded from the U-shaped flow passage 28 finally and allows a detection end 1a and a protective pipe 2 to shortcircuit to emit the alarm of sodium leakage. By this method, erroneous operation due to dust is prevented and the leakage of sodium can be detected certainly.

Title: Semiconductor device and manufacture thereof
Inventor: WATANABE MASAHARU
IPC: C30B15/00
Filed: 1979-07-23
Abstract: PURPOSE: To prevent defects in a laminated layer for a semiconductor device by using a substrate having defects of number larger than 10 5 /cm 2  even after processing it for 18hr at 1,050°C by heating an Si substrate containing a predetermined density of oxygen at 600W900°C for predetermined time to produce defects of number larger than 10 5 /cm 2 .  
     CONSTITUTION: Defects 6 existed in the crystal of a substrate 1 (round bottom pits) have close relationship with defects formed in an epitaxial layer 4 of laminated layer for a semiconductor device. If the round bottom pits are higher in number than 10 5 /cm 2  when heating the substrate at 1,050°C for 18hr in an N 2 , ethcing it and observing it by an optical microscope, the defects in the epitaxial layer 4 of laminated layer fall within an allowable range. This high temperature process enlarges the miniature defects in the substrate to a size capable of observing them. The more the round bottom pits are increased, the less the defects in the epitaxial layer are decreased. Since the round bottom pit density is varied in accordance with the density of oxygen, when the substrate is heated at low temperature of 600W 900°C, the round bottom pit density is increased without increasing the density of the oxygen in the substrate so as to prevent the defects in the epitaxial layer of the laminated layer.
