Title: Video equipment
Inventor: NAKATANI YOSHIHIRO
IPC: H04N5/232
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To operate a touch panel while viewing a finder screen. SOLUTION: In the midst of photographing or reproducing, a driving circuit 12 drives a video display element 10 in accordance with an inputted video signal so as to display a video on the screen of the element 10. The video displayed on the element 10 is transmitted through a half mirror 16 and is made incident on the eye of a user looking in through an observation window 14. The image of an operation menu printed on the transparent or translucent surface of a touch panel switch 18 is reflected by the mirror 16 and is made incident on the eye of the user similarly. When the user puts his finger close to the switch 18, external light is intercepted by the finger, so that a corresponding part gets dark, and when the finger comes in contact with the switch 18 finally, a fingerprint can be observed. When a cover 20 is superposed on the switch 18, the external light is shielded.  In such a case, what is observed through the window 14 is only the display screen of the element 10.

Title: Control valve for hydraulic elevator
Inventor: RAIMO PERUTOOFUIKOO
IPC: B66B1/04
Filed: 1990-11-28
Abstract: PURPOSE: To compensate fluctuation of viscosity of hydraulic fluid by a simple method and always keep a slow speed distance constant by connecting an additional channel with a hydraulic channel system and providing the additional channel with a flow resistance part. CONSTITUTION: A hydraulic channel system 1 is provided with an additional channel 10, in addition to a distributing valve 6 and a throttle 9. During deceleration of an elevator, one flow V2 of flow V1 from the throttle 9 to a speed adjusting plug 2 flows to the speed adjusting plug 2 and the other flow V3 flows from flow resistance parts 12 to 15 in the additional flow channel 10.  Since flow passing through a capillary throttle 12 is inversely proportional to viscosity of the fluid, the flow is increased to nearly ten times as much as that which viscosity is lowered to 1/10, for instance, and also the throttle 9 restricts mass flow but mass of oil does not remarkably change due to a rise in temperature and lowering of viscosity, the volume flow V2 is made to have no relation with fluctuation of viscosity of oil to be used as hydraulic fluid and closing speed of the speed adjusting plug 2 is kept constant.

Filed: 1994-12-27
Abstract: PURPOSE: To speed up the character recognition of a Japanese document by decreasing the number of arithmetic processes for a degree of difference without altering the array order of components of multi-dimensional feature vectors of a character recognition dictionary. CONSTITUTION: Characters to be recognized are divided into plural character groups consisting of characters which are small in degree of difference, and the character groups that the characters belong to and information showing whether or not they are representative characters of the character groups are stored in a character recognition dictionary 1 together with feature vectors. The character pattern of a character to be recognized which is inputted by a character pattern input part 2 is normalized by a character pattern normalization part 3 and then passed to a feature vector extraction part 4, which extracts multidimensional feature vectors consisting of plural feature elements.  An initial candidate selection part 5 compares them with the representative characters of the character groups to select a character group whose degree of difference is less than a selection reference, and a final candidate selection part 6 while sequentially totalizing and adding the degrees of differences by feature elements about all character kinds of the selected character group decides a decision at each time to replace candidate characters. Lastly, a recognition result output part 7 outputs the candidate character of the highest order as a recognition result.
