Patent JP-H01317089-A (JP)
Title: Time base collector
Inventor: SASAKURA TAKAO
IPC: H04N9/89
Filed: 1988-06-17
Abstract: PURPOSE:To attain accurate time base correction by adding a composite synchronizing signal of opposite polarity before synchronization separation to a video signal and giving the result at least once through a variable delay circuit and using the result as a reference for a control clock in the route of an A/D converter, a memory and a D/A converter. CONSTITUTION:A composite synchronizing signal of opposite polarity before synchronization separation is added to one or plural kinds of signals among R, G and B signals being video signals and the resulting signal is passed through a variable delay circuit (summing type comb-line filter constitution circuit) once or for plural number of timers and the resulting signal is used as a reference for a control clock through A/D converters 109-111, memories 112-114 and D/A converters 115-117. Thus, the level of deviated synchronization occurred suddenly due to random noise added to the synchronizing signal is reduced and the result is spread into plural horizontal lines. Thus, the time axis fluctuation of the synchronizing signal being a reference of time base correction is reduced and the operation as the time base collector is always implemented accurately.

Title: Manufacture of semiconductor device
Inventor: ITO SHUZO
IPC: H01L21/22
Filed: 1985-07-08
Abstract: PURPOSE:To unnecessitate the process in which the back side of a semiconductor substrate is coated with a photoresist film as well as to prevent the flaws and contamination generated by the coating of photoresist by a method wherein the thermally oxided film on the back side of the semiconductor substrate is coated with a protective film which can be removed by the same etching process. CONSTITUTION:A semiconductor substrate 11 is oxidized by heat, and thermally oxided films 14 and 15 are grown on the main surface 12 and the back side 13 of the substrate 11. Subsequently, a silicon dioxide film (protective film) 16 of approximately 8,000Angstrom  in thickness is coated on a thermally oxided film 15 by performing a CVD method, and then a photoresist film 17 is made to spray-coat the thermally oxided film 14. Said photoresist film 17 is formed by patterning, and an etching is performed on the thermally oxided film 14 using the pattern-formed photoresist film 17 as a mask. Generally, as the etching speed of the silicon dioxide film 16 is approximately double the etching speed of the thermally oxided films 14 and 15, the thermally oxided film 15 of approximately 4,000Angstrom  is left on the back side 13 even when the thermally oxided film 14 is entirely removed by etching. A thermally oxided film 15 is formed by patterning, and a thyristor, for example, can also be formed by introducing impurities using said film 15 as a mask.

Title: Mirror drive mechanism of automobile
Inventor: ISHIKAWA HIROKA
IPC: A47G1/02
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To adjust the projection amount of two rods individually by only one motor. SOLUTION: When a main gear 20 is rotated and driven by a worm gear 18, a driven gear 22 is moved in right or left interlocking thereto and meshed with a wheel gear with cam 26 or 28. Thus, the power of a motor 16 is transmitted to the wheel gear with cam 26 or 28, which has a cylindrical cam 27 or 29. When the cylindrical cams 27, 29 are rotated, rods 12, 14 are extended/ retreated in response to the movement of the stripe shape guides 27a, 29a formed on its inner wall. As the moving direction of the driven gear 22 is matched with the rotary direction of the main gear 20, the transmission destination of the power can be switched by switching the polarity of the impression voltage to the motor 16.

Abstract: PURPOSE: To improve a tight bonding property, by introducing heavy ions to the boundary between a molybdenum film and an aluminum film.  
     CONSTITUTION: An opening is provided through an SiO 2  film on an n-type layer 2 on a p-type silicon substrate 1. A molybdenum film 5 and an aluminum film 6 are laminated on the opening. Argon ions are injected to set the peak of argon atom concentrationd on the boundary between the films 5, 6. At the time, aluinum atoms are introduced into the molybdenum film due to a knock-on effect. Defects are caused in the films 5, 6 by the ion injection. The density of the defects is maximum on the boundary between the films. Heat treatment is then effected. As a result, a shallow molybdenum-silicon alloy layer 7 is produced, the molybdenum and the aluminum diffuse into each other due to the defects and the films 5, 6 are tightly bonded to each other. The aluminum film is etched by a mixed solution of phosphoric, nitric and acetic acids. The molybdenum film is etched by plasma of CF 4  while using the aluminum of photoresist mask remaining on the aluminum. An electrode pattern is thus provided. As a result, an electrode which does not exfoliate and whose leakage current is small is manufactured on a shallow junction.
