Title: Automatic exposure device for electronic still camera
Inventor: YAMAMOTO TETSUYA
IPC: H04N5/243
Filed: 1987-03-04
Abstract: PURPOSE:To obtain proper exposure by providing a gain variable means varying the gain of a video signal from a solid-state image pickup element continuously in interlocking with an exposure setting means to widen the control region in a pure priority AE mode. CONSTITUTION:When the shutter speed priority AE mode is set, a set shutter speed TV is inputted to operate a proper aperture AV satisfying proper exposure conditions. The proper aperture AV, the apex value AVO at an open aperture F value and the apex value AVmin at the minimum aperture are compared and when the calculated proper aperture AV is within a range of equation AVO<=AV<=AVmin, the exposure control is applied without varying a SVgain. Then at a low brightness limit or below as AV<AVO, the SV gain is increased till the relation of AV=AVO is obtained and the exposure control is applied at the shutter TV while the setting of aperture AV=AVO. In case of a high brightness limit or over having the relation of AV>AVmin, the SVgain is decreased and the exposure control is applied with the shutter speed TV as the aperture AV=AVmin.

Title: Solid-state image pickup element
Inventor: YANO KENSAKU
IPC: H04N5/335
Filed: 1985-03-14
Abstract: PURPOSE:To prevent the reduction of an yield resulting from an increase in a packaging density, by providing outside a semiconductor substrate an overflow drain diode composed of a semiconductor thin film and a light-shielding electrode. CONSTITUTION:In the state (a) in the figure, electrons 30 generated by a photodiode 21 are in a small number, and consequently a rise in energy in the N<+> layer of the photodiode 21 is small. Therefore the electrons 30 do not flow over a barrier of an overflow drain diode 27, but all of them are accumulated. In the state (b), on the other hand, electrons 31 generated by the photodiode 21 are in a large number, and consequently the rise in energy in the N<+> layer of the photodiode 21 is large. Therefore part of surplus electrons 32 flow over the barrier of the overflow drain diode 27 easily toward the outside through a second electrode 272. The height of this barrier can be adjusted by an external bias 29, and so it turns possible to control blooming. This constitution enables the enhancement of the sensitivity to an infrared wavelength and the reduction of the relative difficulty in rules of design and processes of manufacture.

Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To keep the heat insulating function and the wear resistance for long time by constituting refractory materials from grids of austenitic heat resistant steel piled in many layers and formed into a prescribed thickness. SOLUTION: The grids of austenitic heat resistant steels 3 piled in many layers in a stave cooler body 1 having the plane surface in the inner surface to a furnace, are arranged so that this grid surface of the stave cooler becomes the inner surface of the furnace. Since the inner surface of the furnace is the flat surface, this block of the heat resistant steel 3 is dividable into a free size under consideration of the workability, and in the case of working with man-hand, it is desirable to set the size so that the unit weight becomes <=20 kg. This block is not necessary to fix with a chaplet etc., on the inner surface side to the furnace at the molding time of the stave cooler.  Further, the heat resistant steel 3 is not floated up at the casting time, such as inserted brick, but the casting can be executed only by freely laying to prescribed position, and it is not specially needed to execute the treatment etc., before molding.

Title: Long material cutting method
Inventor: SUZUKI TATSUYUKI
IPC: B26F3/04
Filed: 1991-03-14
Abstract: PURPOSE:To reduce the time before the start of cutting and prolong the life of an elastic body by dividing the elastic body for covering long material to be cut, into two pieces, then setting a gap between the divided elastic bodies, and bringing the divided elastic bodies into close contact with each other half- way in pressurization. CONSTITUTION:A glass tube G with a cutout formed therein is covered with elastic bodies 106, 108, and the elastic bodies 106, 108 are compressed by pressurization to perform the cutting of the glass tube G. The elastic bodies 106, 108 are installed with a gap (e) formed between and brought into contact with the glass tube G at the time of closing an upper and a lower molds 101, 102. With the increase of compression, the gap (e) is narrowed until the elastic bodies 106, 108 are finally brought into contact with each other, and the deformed elastic bodies 106, 108 enter cutout parts 109 formed at the side parts between the respective divided faces and the outer peripheral surface. The elastic bodies 106, 108 are then extended laterally around protrusions 110, and the glass tube G is cut being pulled laterally around the cutout. The measure of the gap (e) is so set as to be closed half-way in a pressurizing process, which results in shortening the time before the start of cutting.
