Patent JP-S62105340-A (JP)
Title: Ion generator
Inventor: TOIKAWA SHIGERU
IPC: H01L21/302
Filed: 1985-10-31
Abstract: PURPOSE:To improve the operating rate and control the amount of generated ion easily by providing multiple filaments and dividing them into main filaments and auxiliary filaments. CONSTITUTION:Heat generation and thermal electron emission from filaments 7a-7b are proportional to filament current and the degree of influence of a sputter on the filaments 7a-7c is proportional to the temperature of the filaments 7a-7c. Therefore, influence of the sputter on each filament is lessened by providing multiple filaments 7a-7c. Some of multiple filaments 7a-7c are used as main filaments with the rest as auxiliary filaments and the current flowing through each of the filaments 7a-7c is adjusted or the resistance of each of the filaments 7a-7c is changed. This improves the operating rate and enables the amount of generated ions to be controlled.

Title: Polymerization inhibition of styrenes
Inventor: AOKI TADAMICHI
IPC: C07C67/00
Filed: 1988-09-28
Abstract: PURPOSE:To distill a styrene while still retarding the polymerization of the styrene after the styrene is subjected to a polymerization inhibition treatment by simultaneously using nitrosophenol and mercaptan as polymerization inhibitors in a distillation process for separating and purifying the styrene. CONSTITUTION:The distillation of styrene is carried out in the coexistence of 1 pt.wt. of nitrosophenol and 0.1-30 pts.wt. of mercaptan as polymerization inhibitors under a pressure of 60-200mmHg at 70-130 deg.C. The mercaptan alone exhibits only an insufficient polymerization inhibition action but a combination thereof with the nitrosophenol improves the problems of the nitrosophenol to exhibit the specific effect for reducing the mol.wt. of a by-produced polymer and for retarding the by-polymerization of the styrene after a polymerization inhibition process, thereby permitting the long period continuous stable operation of a plant for producing the easily polymerizable styrene. The polymerization inhibitor is used in an amount of approximately 100ppm converted into nitrosophenol based on the styrene.

Title: Muting device for decorder of dpcm coding
Inventor: EJIMA NAOKI
IPC: G10L19/005
Filed: 1984-11-19
Abstract: PURPOSE:To reduce a pulse noise at muting by providing the 1st gate and the 2nd gate to the output of a DPCM coder and the input of a DPCM decoder so as to make zero a transmission difference signal thereby reducing gradually an analog output. CONSTITUTION:The ON/OFF of muting based on the request of a DPCM coder is controlled by the 1st control terminal 61 and the ON/OFF based on the request of the DPCM decoder is controlled at the 2nd control terminal 81. Since a transmission data in 8-bit is muted digitally before and after a transmission line by the muting ON in both the cases, the DPCM decoder acts that other difference data are zero. That is, the data subject to nonlinear extansion by an inverse quantizer 9 is zero as well, then an input to a leaked integration device 10 is zero and since no new integration data exists, the output of the leakage integration device holds the preceding value. However, since the leaked component exists, the output of the leakage integration device is reduced gradually and reaches zero for some time.

Title: Optical system for correction by light beam scanning
Inventor: KATAOKA KEIJI
IPC: H04N1/113
Filed: 1985-11-01
Abstract: PURPOSE:To improve the effect of correcting face inclination by providing the 1st optical system which makes incident the luminous flux in parallel approximately with a scanning direction on the reflecting surface of a beam scanner and the 2nd optical system which focuses the luminous flux deflected by the beam scanner onto the scanning plane. CONSTITUTION:The 1st optical system consists of cylindrical lenses 8, 9 having respectively focal lengths f1, f2 and makes incident the parallel luminous flux of the shape long in the scanning direction and short in the direction perpendicular to the scanning direction on the reflecting surface of a rotary polyhedral mirror 2. There is therefore no change in the focusing state of the spot on the scanning plane and the good spot image is obtd. even if the reflecting surface rotates. Laser light 3-5 emitted from the rotary polyhedral mirror passes through an ftheta lens 11 and a cylindrical lens 10 and forms the image near the origin of the (y) direction on a photosensitive body 12. The laser light is stopped down to about y=f3phi by disposing the lens 10 to the position apart approximately by f3 from above the photosensitive body if the laser light is emitted in the direction of the optical axis with angle phi like 3-6 owing to the face inclination of the rotary polyhedral mirror. The effect of correcting the face inclination is thus improved.

Abstract: PURPOSE:To open a contact hole in an intermediate insulation film efficiently and satisfactorily by forming an aperture in resist, ion-implanting impurity where a hole is to be made in the intermediate insulation film and etching with a solution which contains dilute fluoric acid using resist as a mask. CONSTITUTION:An aperture 8 is formed in resist 7 and impurity such as phosphorus, boron, arsenic is ion-implanted where a hole is to be made of PSG6 from the aperture 8. Then, the PSG6 is etched with a solution which contains dilute fluoric acid, e.g., mixture of hydrofluoric acid and ammonium fluoride, using resist 7 as a mask. In this case, the etching speed at an aperture 9 where impurity is ion-implanted is faster than the etching speed at the other portion where impurity is not ion-implanted and anisotropy etching can be carried out. In this way, the etching is finished forming a contact hole 10 in the PSG6. In this case, shortening of the time reduces etching to transverse direction under the resist 7.
