Patent JP-2003153084-A (JP)
Title: Controller of solid-state image pickup device and control method thereof
Inventor: IDE TAKASHI
IPC: H04N5/376
Filed: 2001-11-08
Abstract: PROBLEM TO BE SOLVED: To enlarge a dynamic range without blooming. SOLUTION: A solid-state image pickup device 4 is constituted by arraying a photodiode on a semiconductor substrate in a matrix shape and arranging a vertical electric charge transfer register in each column of the photodiode. When a subject is at high luminance, a substrate voltage control circuit 6 lowers a voltage applied to the semiconductor substrate from about 10 V to about 1 to 2 V. This causes to increase an overflow potential barrier formed in a lower part of the photodiode, thereby accumulating much more electric charges. Simultaneously, a vertical register drive circuit 8 lowers a voltage at a high level of a transfer pulse applied to a transfer electrode of the vertical electric charge transfer register to a negative side voltage.  As the result, a potential barrier between the vertical electric charge transfer register and the photodiode is raised and a signal electric charge is difficult to overflow to a register side, thereby preventing from blooming.

Filed: 2001-10-05
Abstract: PROBLEM TO BE SOLVED: To provide a picking prevention device of a cylinder lock capable of preventing the cylinder lock from being unlawfully unlocked because the new developed cylinder lock is so constituted that a usual picking tool can not be used.

IPC: E02B7/20
Filed: 2001-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a flexible film dam easy in manufacture and installation to a base even if the dam is enlarged, and facilitating repairing and replacement, and a flexible film dam installing structure for installing and processing this flexible film dam on the base. SOLUTION: A flexible film 18 is formed as a three-layer structure having vertically arranged rubber film bodies 20 and 22, and a reinforcing wire body 24 arranged between these rubber film bodies 20 and 22, and separated from the rubber film bodies 20 and 22. Since the rubber film body 20 shares the action for maintaining sealing performance of the flexible film 18 and the reinforcing wire body 24 shares the action for maintaining strength, airtightness, strength, and rising stability can be secured without excessively thickening the whole flexible film 18. Thus, the flexible film 18 can be easily manufactured, and repairing and replacement result in only a required layer. A structure of respective layers can be simplified by specifying the function required for the respective layers.

Title: Intraoral disintegration type solid preparation and its production
Inventor: KATSUTA TOSHIFUMI
IPC: A61K47/10
Filed: 2001-11-14
Abstract: PROBLEM TO BE SOLVED: To provide an intraoral disintegration type solid preparation that readily dissolves or disintegrates in the oral cavity and to provide a method for producing the preparation. SOLUTION: A melt that includes saccharides (monosaccharides, disaccharides or sugar alcohols) and medicinal components are sprayed and dispersed in an atmosphere as a temperature lower than the melting point of the saccharides to solidify the melt in a fibrous or web form. The resultant web are collected and formed to a prescribed dosage form. Since this solid preparation is produced from the fibrous or web form, a high void percentage can be secured. In addition, because saccharides of high water solubility are used as base materials, the preparation readily dissolves and disintegrate in the oral cavity and can easily and safely be dosed with their sweetness.

Filed: 2001-12-13
Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem in which temperature adjustment of cooling water circulated in an engine under test by means of a gain controller with the fixed time constant, causes supercooling or undercooling of the cooling water to occur due to change in engine's number of revolutions (rpm), which has an adverse effect on testing accuracy.  <P>SOLUTION: A function generator 11, when a speed of the engine under test 1 is in idling range, increases in direct proportional to the speed, and when the speed of the engine under test 1 is in idling range or over, the output of polygonal line characteristic where it becomes a fixed value, is obtained. A comparison arithmetic section 12 adjusts forward gains by multiplying deviations between temperature set values of the cooling water and their detection values by the outputs of the function generator using a multiplier 12B. A PI arithmetic section 13 performs proportional plus integral computation of the outputs of the comparison arithmetic section, and adjusts backward gains by multiplying these by the engine's speed using a multiplier 13B. Temperature adjustment of fuel and engine oil for the engine under test is the same as the above.  <P>COPYRIGHT: (C)2003,JPO

Title: Floor panel for bathroom
Inventor: KITAKADO TOSHIMI
IPC: E03C1/20
Filed: 2001-12-13
Abstract: PROBLEM TO BE SOLVED: To provide a floor panel for a bathroom surely dried on the next day. SOLUTION: When water falls on a surface of the floor panel 1, surface tension is broken down by a recess-projection-shaped part 8, and the water expands without forming a drop of water indicated by an imaginary line. A flow speed of the water reduces by the recess-projection-shaped part 8, the water flowing in a passage 7 does not break off, and a drain speed of the water is low so that residual water isolated in an island shape does not remain. Even when the water remains in the recess-projection-shaped part 8 after the water flows in the passage 7, since a quantity in this case is extremely small, the water evaporates in a short time.
