Patent JP-H11331847-A (JP)
Title: Image conversion method, digital camera and computer system
Inventor: RATNAKAR VIRESH
IPC: H04N1/41
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To execute a selected spatial domain operation by directly operating an image compensation domain expression not through a complete expansion and compression process. SOLUTION: In this image processing method including an operation of image compression domain expression to attain desired spatial domain processing without the need for complete expansion and compression processing, a discrete cosine transform DCT domain information processing 42 is executed after an entropy decoding 41. The DCT domain image processing 42 includes approach processing for eight operations in a D4 (square symmetrical two-plane group) on a joint photographic experts group JPEG image. As to a task such as 90-degree rotation of the image (operation is the D4 ), a speed is increased by almost quintuple of that of a method based on a space domain according to a method based on a DCT domain. The processing method based on a simple compensation domain is sufficiently adapted to an image processing task required for a still camera system adopting the JPEG.

Title: Grease-feed detecting method
Inventor: YOKOYAMA SHUICHI
IPC: F16N29/00
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To provide a grease-feed detecting method-that is able to prevent any heat generation, abrasion or the like of bearing parts set at rolling and sliding contact parts by determining whether they are greased or not with reliability. SOLUTION: Temperature sensors 6 are placed just outside or inside respective bearings 50 to measure and store their temperatures prior to greasing. These stored temperatures are compared with the respective temperatures that the temperature sensors 6 detect when a grease feed pump 2 works to apply grease G to the bearings 50. A difference between those temperatures produces a determination of well greasing, and no temperature differences a determination of no greasing.

IPC: G01N33/18
Filed: 1987-04-15
Abstract: PURPOSE:To effectively recognize fishes in an image by providing partition plate for straightening and diving weir plate in a water tank. CONSTITUTION:Water is fed to and discharged from the transparent water tank 10 and fishes 18 are kept in the space between partitions 11A and 11B made of wire netting and porous plates. The diving weir plate 12 is provided on the downstream side of the partition plate 11B.

Title: Magnetic disk device
Inventor: MAEKAWA HIDEO
IPC: G11B19/20
Filed: 1987-04-15
Abstract: PURPOSE:To lower the temperature rise of a spindle due to heating of a drive motor by disposing the drive motor to the outer side of a hub, coupling a rotor of the drive motor with the hub at an edge surface of the hub and constructing the hub mounted with a magnetic disk to be rotated with its outer wheel via bearings around a fixed shaft.

Title: Door device
Inventor: KISHIMOTO TOSHIYA
IPC: G02F1/13
Filed: 1993-03-24
Abstract: PURPOSE:To prevent a collision and maintain the privacy of the indoor state by applying a current to the liquid crystal layer of a door to make the door transparent in the case of detecting passing bodies by both switches provided on both sides of the glass door, and placing the liquid crystal layer in the current non-applied state in other cases so as to make the door opaque. CONSTITUTION:When a detecting switch 38 detects a passing body 41, a detection signal is sent to the AND circuit 43 of a glass control part 33. A safety switch 32 sends a detection signal to the circuit 43 if a passing body 42 exists in the opening/closing area of a door 34. In the case of only one of the passing bodies 41, 42 passing the door, the door glass is placed in the opaque state alike the closed state of the door 34. In the case of two detection signals being inputted, the circuit 43 sends a signal to a voltage supply circuit 44, and the control part applies a current to a liquid crystal layer 35 so as to place the glass in the transparent state. Upon the lapse of the specified time after the start of the timer of the circuit 43, current application to the liquid crystal layer 35 is stopped, and the glass becomes opaque. Collisions are thereby reduced remarkably while making it hard to see the indoor state, and the current application time is shortened to prevent the consumption of the liquid crystal layer.

Title: Food transport apparatus and food sorting apparatus
Inventor: KATAOKA NOBUYOSHI
IPC: B07C5/02
Filed: 1993-04-19
Abstract: PURPOSE:To improve the capability of sorting food by providing a fixed interval arranging mechanism for traveling food in a line at specific intervals. CONSTITUTION:Potatoes 3a, for example, supplied to a fixed interval arranging mechanism 4 are traveled in a line at specific intervals according to the pitch of a machine 14 in such a manner that the central position in the direction intersecting perpendicularly to the traveling direction A is set in the substantially central position in the lateral direction of a transport conveyer 8. In the case of transferring the potatoes 3a from the fixed interval arranging mechanism 4 to a transport mechanism 5, the potatoes 3 are always transferred from the lower end position of a rubber belt 13 of the fixed interval arranging mechanism 4 to the transport conveyer 8 regardless of the size of a potato 3a. Accordingly, the potatoes 3 are prevented from jumping on the transport conveyer 8 to make the longitudinal intervals of potatoes 3a in the traveling direction A uneven and from coming into contact with each other. Thus, the capability of sorting food 3 (e.g. potatoes 3a) can be improved in a simple structure.

Filed: 1988-04-13
Abstract: PURPOSE:To automatically extract the picture data of the face and so on of an operator by providing a transmission source at a handset and a means to detect the position of the transmission source received from a television camera respectively. CONSTITUTION:A television camera 6 picks up the face of a user 2 to have a handset 1. Then, when the user 2 executes communication with the handset 1, the positions of infrared emitting element 3 and 4 fitted to the handset 1 are detected by an infrared picture processing part 30. The picture data of the face are extracted by a visible light picture processing part 31 from a detected coordinate. Next, since the position of the handset 1 moves corresponding to it if the user 2 move, the extracting area of the picture data of the face follows corresponding to the movement. As a result, the extracting of the picture data of the face is always executed accurately independently to the position of the user 2.

Filed: 1993-04-19
Abstract: PURPOSE: To measure a curvature of a reflection surface such as a mirror by transmitting an electromagnetic radiation beam to a sample reflection surface, and measuring an angle deflection of a reflection element which makes the reflection radiation converge into a detector. CONSTITUTION: On a platform 8, a detector 9 and a lens 10 which sends, to the detector 9, radiation beam 11 reflected on a lens 4 where the curvature of a surface 5 is measured, are provide. In addition, a mirror (reflection element) 12 is so attached that it is rotated by a mirror rotation means 13 around an axis 14. A means 13 generates a signal representing an orientation of the mirror 12. The signal is, together with the signal which the detector 9 generates, applied to an analogue/digital converter 16. Change in orientation of the mirror 12 which is required for the beam 11 to be incident on the detector 9 is related to an angle θ between an incident beam 7 an the reflection beam 11, and it is decided by a processor 18. By knowing the angle θ and a movement distance of a platform 1, the curvature of the surface 5 of the lens 4 is calculated.
