Title: Manufacture of semiconductor device
Inventor: SERIKAWA TADASHI
IPC: H01L21/3205
Filed: 1982-09-10
Abstract: PURPOSE:To make flat the surface of semiconductor device by selectively removing a conductive film at the side wall of lift-off material layer and then removing a conductive film on the lift-off material layer together with a lift-off material layer after forming said conductive film on a semiconductor substrate providing both lift-off material layer and insulating film at the upper surface. CONSTITUTION:An insulating film 42 such as SiO2 is deposited on a semiconductor substrate 41 and a resist pattern 43 consisting of a polymer material is also formed thereon. After the ion beam etching is carried out with such resist pattern used as the mask, a conductive film 44 is deposited almost in the same thickness as an insulating film 42 with the sputtering method. The film at the side wall of resist pattern is removed selectively by a corrosion liquid and then unwanted conductive film is removed together with the resist by the lift-off process. Thereby, the conductive film 44 is buried under the insulating film 42. Thereafter, the insulating film 45 is deposited, the resist pattern 46 is formed, and a through hole 48 is bored with said resist pattern used as the mask, and the pattern 46 is removed. Finally, a wiring pattern 47 consisting of aluminum Al is formed and thereby a semiconductor device can be completed.

IPC: C22C38/00
Filed: 1978-12-21
Abstract: PURPOSE: To raise the sintering density of an iron-cobalt type sintered soft material and improve the magnetic properties thereof by adding a restricted amt. of phosphorus to the material.  
     CONSTITUTION: Phosphorus 0.05W0.7wt% is added to blended powder consisting of cobalt about 30W65wt% and the balance iron. After adding a lubricant the mixed powder is molded and sintered to manufacture a soft magnetic material. Since the restricted amt. of phosphorus is contained, this material has raised sintering density and enhanced properties such as high magnetic flux density, low coercive force and high permeability which are desirable for a magnetic material. Thus, characteristics like those of a molten material are provided.

Title: Apparatus for inspecting defect
Inventor: KUBOTA TAKASHI
IPC: G01N21/956
Filed: 1994-07-08
Abstract: PURPOSE:To detect a defect and specify position of the defect by synthesizing going light showing a substrate pattern and returning light representing a defect image. CONSTITUTION:A laser light from a light source 1 is collimated by a lens 3 to a parallel luminous flux 100. A light 101 passing through an object to be inspected 4 forms, after passing through a half mirror 5, a Fourier transformation image on the rear focal plane by the diffraction of a lens 6. A space filtering element 7 of a reflecting type is arranged at the Fourier transformation face to cut only light of components of a regular pattern. The reflecting light after being filtered is subjected to an inverse Fourier transformation by the lens 6, returned to be a parallel light 102 and reflected at the mirror 5, thereby, a defect image from which the regular pattern is removed, is detected at a screen 8. The defect image detected from the luminous flux 102 (returning light) and a substrate pattern obtained from a luminous flux 104 (ongoing light) are synthesized on the screen 8. Accordingly, since the defect image is emphasized in the substrate pattern, not only the defect is confirmed, but also the position of the defect can be specified.

Title: Ejection device of cassette tape recorder
Inventor: USUI KATSUO
IPC: G11B15/675
Filed: 1984-07-30
Abstract: PURPOSE:To prevent a malfunction due to the operation timing as well as the generation of a secondary defect by actuating a power assist release means in an early process of an ejection operating lever for cassette to release the forward movement of a head plate and then actuating an ejection means. CONSTITUTION:A power assist release lever 76 is turned in an early process where an ejection lock slide lever 75 is pressed by a pressure arm part 16b of an ejection slide lever 16. Then a power assist release plate 77 is also slided to turn a power assist action plate 38. Thus a pressed engagement is released between a power assist action plate 38 and a head plate 22. As a result, the head plate 22 has no driving force any more and is moved back by a return spring 31. Thus the ejection of a cassette is possible. When the lever 16 is pressed continuously, a cassette store frame 98 is hanged by a cassette hanging plate 7 and then moved up by means of a right cassette store frame lift member 13 which is turned in response to a sliding action of the lever 75.

Abstract: PURPOSE:To attempt the enhancement of the operation efficiency after the completion of the magnification copy cycly or the operation of selecting the magnification  when the non-copy operation continues for a predetermined period of time by  automatically returning the above operation to an equal size copy state. CONSTITUTION:In the state where copy is possible, when automatic magnification return circuit I and magnification selection circuit II are applied by voltage, transistor TR 1 becomes conductive, and terminal A of timer circuit III is supplied by input signal, volatage V2 of point P2 increases with the set time constant. Meanwhile the reference voltage of comparator C is constant voltage V3 at point P3, and if V2 > V3, the comparator C works to render voltage of terminal B grounded voltage. To this end, TR2 is conductive to supply output signal to reset terminals R1, R2 of relays RL 1, RL 2 via diode D4 so that both relays are made to be reset state and the same result obtained from the operation of push button  switch SW1 for the actual size copying is artained. In addition, the predetermined  interval time can be determined by variable resistor VR of the circuit III and the  value of capacitor C1. Accordingly, the efficiency of copy work can be improved.
