Title: Method for dry etching
Inventor: HAYASAKA NOBUO
IPC: H01L21/302
Filed: 1984-12-25
Abstract: PURPOSE:To enable the anisotropic etching of a few damages without decreasing an etching rate by irradiating the predetermined region in an etching chamber with the light including the wavelength absorbed by the gas introduced into the etching chamber. CONSTITUTION:On the side walls of a vacuum chamber 11 forming an etching chamber, windows made of transparent plates 21 and 22 are formed. In this constitution, the light 24 from a light source 23 irradiates a discharge region between electrodes 12 and 13 through the plate 21 and is led out through the plate 22. For a sample 16, N<+> polysilicon is used and Cl2 is introduced thereby effecting the etching using an excimer laser as a light source. The etching rate is much faster than that when light irradiation is not utilized and a damage is hardly seen. Since this method is able to make a difference in potential smaller and the etching rate faster besides to reduce damages, it is suitable for the minute processing.

Abstract: PURPOSE:To execute the fast changing-over of a track and to shorten the time needed for a retrieving action by outputting a control signal corresponding to the phase difference in the changed-over track to a PLL circuit and a processing circuit by a generating means when the track is changed over by a selecting means. CONSTITUTION:When a PCM sound signal from a track 1 is reproduced and a track is changed over so as to operate a selecting means 17 and reproduce the PCM sound signal from a track 3, the selecting means 17 controls a delay circuit 16 so as to output a switching pulse SWP and a reference signal VD phase-advanced for two tracks only to the switching pulse SWP and the reference signal VD. As the result, the delaying circuit 16 outputs the switching pulse SWP and the reference signal VD phase-advanced for two tracks only from the time of the changing-over. At such a time, the selecting means 17 outputs the signal corresponding to the phase difference of the track before and after the changing-over to a generating means 31. The generating means 31 outputs the control signal to a switch 32 and turns off a time switch 32 corresponding to the phase difference.

Title: Production of ice
Inventor: TORII SOHEI
IPC: F25C1/00
Filed: 1994-11-07
Abstract: PURPOSE:To produce ice of a size of certain degree by directly supplying water uniformly seasoned or colored by dissolving dye, sweetener, etc., to a surface of an icemaker cooled to a specific temperature range to allow the water to flow on a surface of the icemaker, and forming an ice layer on the surface of the icemaker. CONSTITUTION:Charged and cooled colored water is sprayed over an inner wall of an icemaking can 1 cooled to -5--2 deg.C from outside by a sprayer 4 to become a thin film and to allow the film to flow to a bottom. It is iced in a film state in the process. It is iced while flowing from an upper part of the inner wall to the bottom, and subsequently sprayed and supplied colored water is allowed to similarly flow on a surface of the filmlike colored ice layer, thereby forming a filmlike ice layer. Thus, the layer is laminated, and increased in thickness toward a center. Further, when the colored water remains in the bottom of the can 1, it is continuously sucked by a suction tube 7 connected to a pump 6, returned to a colored water storage tank 3 so that the colored water does not remain in the can 1.

Filed: 1986-11-18
Abstract: PURPOSE:To improve the tracking performance of pump drive and to prevent a pump well from being flooded by outputting a start command to a pump by an OR output between an AND output between a water level deviation signal and a turbidity signal and a signal of a water level arithmetic circuit. CONSTITUTION:A water level deviation detection circuit 3 differentiates a water level signal 2 of a pump well 20 and outputs a water level deviation signal 4 when the result reaches a specified value or over. When a turbidity detection circuit 6 outputs a turbidity signal 5 when a turbidity signal 5 of the pump well 20 reaches a prescribed value or over. An AND circuit 8 ANDs the signals 4, 7 to output a start signal 11. Moreover, when the level of the signal 2 reaches a preset water level, a water level arithmetic circuit 9 outputs a start signal 10 and an OR output of an OR circuit 12 between the signals 10 and 11 becomes a start command 13 to the pump 14. Through the constitution above, when the pump well 20 is small or a water flow is too much due to a large rainfall, the start command of the pump is outputted quickly to improve the pump tracking performance thereby preventing the pump well from being submerged.

Title: Ferromagnetic metal powder coated with methyl ethyl ketone polycondensate and manufacture thereof
Inventor: OSHIMA KAZUFUMI
IPC: C09D5/23
Filed: 1984-12-27
Abstract: PURPOSE:To obtain the ferromagnetic metal powder applied to audio-appliances and VTRs which consists of iron mainly and has the exceedingly improved characteristics by using Fe including P, Si and/or B treated with a methyl ethyl ketone polycondensate as a main component. CONSTITUTION:The ferromagnetic metal powder fine particles mainly consisting of iron for this use are manufactured by coating a surface part of the fine particle of needle iron oxyhydroxide with a shape retentive component and subjecting the particles to cleaning, drying, and milling followed by calcination and gas-phase catalytic reduction. For the shape retentive components, the reduced iron powder fine particles preferably include P, Si and/or B within a range of P=0.1-5, Si=0.1-5, B=0.1-5 atomic weight percentage to Fe. If the percentage is under the above range, the polycondensation performance of methyl ethyl ketone is low and the effect that the characteristic of deterioration with aging of the ferromagnetic metal powder fine particles is improved is diminished. If the percentage is over the range, the polycondensation of methyl ethyl ketone progresses too intensively so that the dispersion property during a step of conversion into coating compositions is lowered though affinity for a binder resin is improved.
