Patent JP-S6484081-A (JP)
Title: Refrigerator
Inventor: NAKAMURA TOSHIBUMI
IPC: C23C22/84
Filed: 1987-09-22
Abstract: PURPOSE: To prevent vegetables in a refrigerating compartment from becoming rotten at a high external air temperature without disabling temperature control in the freezer at a low external air temperature by alternately aligning at least two rows of square holes side by side at the boundary line part between the refrigerating compartment and a third compartment on the cover of a temperature-controlling device. CONSTITUTION: Two rows of square holes 18 are alternately aligned side by side at a boundary part 17 of a refrigerating compartment 3 of a cover 9 of a temperature-controller 8 and a third compartment 4. The temperatures of the refrigerating compartment 3 and the compartment 4 are controlled to approximately 3-5 deg.C and -3 deg.C, respectively, and the temperature difference between both compartments is 6-8 deg.C.  Therefore, the temperature of the cover 9 is cooled at the side of the refrigerating compartment 3 but heat conduction is broken by the square holes being arranged at the boundary part 17 of both compartments 3 and 4 and at the same time heat conduction distance is extended since the square holes 18 are alternately aligned, thus preventing cooling and hence preventing defrosting and formation of dews from occurring regarding the heat conduction of the cover 9 among the square holes 18. In this manner, two rows of square holes 18 are alternately aligned side by side and the cover 9 is opened thus preventing the strength of the cover 9 from decreasing and the disabling of temperature control of the compartments 3 and 4 and then vegetables in the compartment 3 from becoming rotten.

Title: Method for recording and reproducing video signal
Inventor: SASAKI KIYOSHI
IPC: H04N5/7826
Filed: 1985-10-24
Abstract: PURPOSE:To obtain a normal picture at the time of a variable reproduction even in segment recording by dividing a magnetic tape in a width direction and recording the same segment at the same position in the width direction on the magnetic tape. CONSTITUTION:The upper and lower halves of a field are recorded on tapes I and II parts, respectively, as tracks 2 and 2'. Such recording is executed by a rotating drum incorporating a magnetic head. The width (h) of the rotating drum is the same as a distance (h) between tracks. Thus the tracks 2 and 2' are recorded by the heads 5 and 6. The rotational frequency of the drum is twice frame frequency. If patterns, whose 1st and 2nd fields are recorded in the group of F1 and F2 and that of F3, F4... as figure shows, are reproduced at a four-times speed, locuses 8 and 9 drawn by a reproduction head turn out to be things denoted by symbols 8 and 9. Thus respective parts S1-S8 in the F1-F3 are reproduced. Since on this screen each segment is reproduced at the proper position on an original screen, it becomes a normal screen.

Title: Controller for attitude of antenna on travelling object
Inventor: SUZUKI KATSUO
IPC: H01Q1/27
Filed: 1989-09-14
Abstract: PURPOSE:To make the antenna tracking device small and the weight light by controlling the antenna directivity in an object direction with a small range of scanning corresponding to a change in a travelling object with respect to a slow motion of a vehicle or the like and applying search scanning of a wide range with respect to an extremely fast motion. CONSTITUTION:While a reception level of antennas 31, 32 is a 1st setting value TH1 or over, a 1st control means 1 corrects the deviation of the directivity of the antennas corresponding to a change in the detection value of attitude detection means GYrp, GYya. When the reception level is less than the 1st setting value TH1 and at a 2nd setting value TH2 or over, a 2nd control means 1 scans the antennas 31, 32 in a small range. When the reception level is less than the 2nd setting means, a 3rd control means 1 applies search scanning to the antennas 31, 32. While the reception level is at a prescribed value TH1 or over, a 4th control means 1 clears an accumulated error in existence in the detected change for each prescribed time. Thus, it is not required to provide specially high response to the antenna attitude control system.

Title: Method of writing and reading magneto-optical carrier, and its device
Inventor: YOHENESU HENDORIKASU MARIA SUP
IPC: G11B11/105
Filed: 1990-09-07
Abstract: PURPOSE: To increase information density without decreasing a radiation spot in diameter by writing a magnetic domain according to a varying ratio of a domain length to a domain period in the scanning direction so that a different ratio expresses a different signal value of the written signal. CONSTITUTION: Without making a frequency and an amplitude of an activated current to be dependent on a written information signal, this frequency is made equal to an optical cut-off frequency-fco concerning a size of a scanning spot at least. Further, a ratio of a square wave time interval to a frequency of the activated current is modulated according to the information signal, and a magnetic domain is written according to a varying ratio of the domain length 4 in the scanning direction to the domain frequency so that this different ratio expresses a different signal value of the written signal. As a result, when a local temperature of a recording layer becomes a maximum, an external magnetic field has a sufficient strength of a desired direction to surely magnetize the local area.

Title: Sheet material separating device
Inventor: KAMEYAMA TORU
IPC: G03G15/00
Filed: 1989-09-13
Abstract: PURPOSE:To dissolve wear of a resistance member and impossible supply of sheet material therefrom by a little inclining both side edge parts of a resistance member to the center side of the resistance member against the sheet material feeding direction. CONSTITUTION:When sheet material S comprising an envelope of hard paper or an envelope with bent-up extreme end is fed from a loading table 43 with paper feed rollers 55 and the extreme end part abuts to a resistance member 5, strong force is applied on both side end parts 5a of the resistance member 5 to begin to wear, and by continuing the paper feed, wear is apt to spread step by step on the lower stream side. But as the both side end parts 5a are obliquely formed in the lower stream direction, a little advanced wear part reaches the lower stream side end parts not to spread largely in the lower stream side. Therefore, a phenomenon which the wearing part of the resistance member 5 is formed to be scooped and the extreme end part of the sheet material S is repelled with the scooped wearing parts and impossible supply of the sheet material thereby, is dissolved.

Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To provide a method and device for dry etching by which dry etching can be performed safely at a low cost by using a reactive gas produced by utilizing gas discharge under the atmospheric pressure or its vicinity. SOLUTION: A stable reactive gas is produced by supplying an inert and stable halogen gas to a discharge unit 2 from a gas supplying source 6 and causing discharged under the atmospheric pressure or its vicinity and introduced to a separated treating chamber 4 through a transport pipe 5 provided with a heater 6 for preventing the formation of multi-association molecules. In the chamber 4, an object 3 to be treated is etched by exposing the object 3 to the reactive gas. The product of the reaction between the reactive gas and the object 3 and the excessive amount of the reactive gas are forcibly discharged from the chamber 4 by means of an exhauster 8 and discharged to the outside after the product and gas are purified by means of a pretreatment device for discharge.  When the reactive gas does not react directly to the object 3, the reactive gas is again made to react to the object 3 by introducing steam from a steam generating means 9 to the chamber 4 so as to produce a more active gas for etching. Therefore, the facility and treatment costs can be reduced and the safety, productivity, and workability can be improved. In addition, the practically applicable field of this method and device for etching can be widened.
