Title: Electronic still camera
Inventor: OTA YOSHITAKA
IPC: H04N5/238
Filed: 1989-04-13
Abstract: PURPOSE:To realize auto-bracketing at simultaneous or overlapping timing by controlling the operation of the sweep-off and the read-in of two fields by which an image pickup element executes exposure independently at each field. CONSTITUTION:An FIT-CCD with the memory of one frame portion is used, and it is driven beforehand at a frame accumulation mode. At first, the signal of a field A is read out, and is swept off by reverse transfer (figure (b)1), and after leaving an adequate time interval, the signal of the field B is read out, and is swept off by the reverse transfer ((c)2), and the signal of the field B is transferred to a memory part ((c)3), and afterwards, the signal of the field A is transferred to the memory part ((b)4). Then, the signal of the field B is read out by video rate, and after being processed by a processing circuit and a recording circuit, it is recorded in a video floppy ((e) REC A). Thus, since the exposing timings of two fields are overlapped, difference never causes any problem.

Title: Substrate for optical recording medium
Inventor: TANAKA FUJI
IPC: G11B7/24047
Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration of the jitters in a reproducing signal by forming a guide groove guiding an irradiating position of a laser beam along a track, nearly paralleling an advanced phase axis of intrasurface birefringence for the tangential direction of the guide groove and recording an information signal on an area between the adjacent guide grooves. SOLUTION: A disk substrate 2 is molded so that a groove 6 for guiding an irradiation device of a laser beam L of a recording/reproducing device is formed spirally on one main surface, and the advanced phase axis of the intrasurface birefringence becomes nearly parallel to the tangential direction of the groove 6. Further, a magneto-optical recording phase 3 is formed on the one main surface of the disk substrate 2 formed with the groove 6, and its cross section becomes a rugged shape. A land 7 between the grooves 6 is made a signal recording area. Thus, a phase difference caused by the intrasurface birefringence of the disk substrate 2 is canceled with the phase difference caused by that the laser beam L is emitted over the land 7 and the groove 6, and the astigmatism is corrected, and the proper reproducing signal is obtained.

Abstract: PURPOSE:To equalize the seasoning of a material to be cooked and the condition of heating of the surface while improving shape after boiling by a method  wherein a seasoning liquid is frozen once, thawed by the heating and cooking of  the material to be cooked, returned to the seasoning liquid and heated by high  frequency while being dropped. CONSTITUTION:Solid agents 6 for seasoning obtained by freezing, solidifying or semi-solidifying the seasoning liquid 3 for seasoning the materials to be cooked  2 are prepd. while the materials to be cooked 2 are encased into a heat-resistant vessel 5. The thawed liquid or dissolved liquid 3 of the solid agents 6 for seasoning is dropped to the materials to be cooked by a dropping body 7 with holes 10 passing the thawed liquid or the dissolved liquid 3 while a cover 11 is placed detachably onto the dropping body 7. The dropping body 7 and the cover 11 are formed by a material through which a high-frequency electric wave does not pass. That is, the seasoning liquid 3 is frozen once, thawed by the heating and cooking of the materials to be cooked, returned to the seasoning liquid and heated by high frequency while being dropped, thus allowing excellent cooking. The materials to be cooked are cooked uniformly because the seasoning liquid is sprayed onto the surfaces of the materials to be cooked at all times.

IPC: H01L21/302
Filed: 1986-04-24
Abstract: PURPOSE:To etch the whole surface of a member to be ehuted consisting of silicon having a large area in the uniform quantity of etching by previously determining the consentraion of O2 gas, through which the etching rates of a control section and peripheral section are equalized, and using a mixed gas containing such O2. CONSTITUTION:An silicon wafer 4 coated with a mask composed of Al is position onto a cathode plate, the inside of a tank is evacuated, SF6 gas from an introducing port 7 ans O2 gas form an introducing port 8 are mixed and introduced, and high-frequency power is applied between both pole plates 2, 3 by a power supply 9 to generate plasma in a space 10, thus etching the surface not coated with the mask in the wafer 4. Since S generated by the decomposition of SF6 is oxidized to SO2 by adding O2 gas ans the action of S is prevented at that time, an etching rate is increased, but the quantities of an outer circumferential section and a central section etched alter when the concentratrion of O2 is augmented gradually. The quantity of O2 is controlled to a value at sections close to A and C where dispersion reaches zero, and the wafer is etched. Accordingly, dispersion in the surface is improved remarkably.
