Title: Sectional lighting point-of-purchase advertising article
Inventor: NAKAE YASUSHI
IPC: G09F13/18
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To obtain a Point-Of-Purchase advertising article which is usable in the sample exhibition chambers of a vending machine and transmits light to glitter a front surface by utilizing light sources from flanks without using separate power sources by providing the end of this article with a plurality of light transmission rods of elongated columns which are bent to the front surface and are directed in their cross sections toward the front surface. SOLUTION: Both ends of the light transmission rods 2 of the elongated columnar shape are bent to the perpendicular shape round at the corners toward the front surface and the cross sections 1 are directed toward the front surface. The flanks of the light transmission rods 2 formed with a broad U shape by bending both ends are then connected at the top and the bottom, by which a raft plate 3 bend on both sides to the front surface is formed. This raft 3 bent on both sides is housed into a transparent case 4. This transparent case 4 has a D-shaped bottom and forms a shape opened in the central portions of the top surface and the rear surface. The raft plate 3 is housed into this case, by which the portion of the bottom is formed as a plane and the case is securely adhered and mounted at the top surface of a merchandise sample 5.  The light entering from the flanks of the columnar light transmission rods 2 bent at the ends toward the front surface transfers the inside of the light transmission rods 2 so that the light is emitted from the sectional surfaces, which are directed to the front surface, to glitter the sectional surfaces.

Title: Cooling and preservation of food
Inventor: TANAKA KAZUO
IPC: A23B4/06
Filed: 1989-07-17
Abstract: PURPOSE:To extremely rapidly and uniformly cool a fish or livestock food to a temperature range for preserving the food by freezing from the surface of the food to about the half of the food at <= the intrinsic freezing point of the food, rapidly thawing the food with a cooling medium corresponding to the intrinsic freezing point and making the whole food into a uniform temperature. CONSTITUTION:For example, when a food is fish, caught mackerel, sardines, etc., are frozen from the surface of fish to about 1/2 thickness of fish with salt brine at -10 deg.C and immediately thrown into ice salt water at about -2 deg.C corresponding to the freezing point of the fish. Then the frozen layer of the outside of the fish is softened and simultaneously cooling is progressed in the interior by latent heat of melting in the circumference. Consequently, the frozen part at the outside of the fish and the unfrozen part in the interior are thermally uniformarized approximately at the intrinsic freezing point of the fish and the fish is extremely rapidly and uniformly cooled into the objective preservation temperature range. Since the frozen part is thawed, there is no fear of growth of ice crystal.

IPC: A61B5/0245
Filed: 1987-07-23
Abstract: PURPOSE:To extend the life of a light emitting element and to prevent energy loss, by providing a fingertip detection sensor for detecting the presence of the fingertip in a blood flow pickup and allowing the light emitting element to light when the fingertip is inserted in the blood flow pickup and stopping the lighting of the light emitting element when the fingertip is not inserted or limiting the quantity of emitted light. CONSTITUTION:When a person to be measured inserts his fingertip 10 in a blood flow pickup 1, the light emitted from a light emitting element 2 transmits the fingertip 10 of the person to be measured to be received by a photodetector 3 and the variation of the received light thereof is detected in the pulse wave detecting part 6 within an acceleration pulse wave converter 5. Since it is cleared that the fingertip 10 is present in the blood flow pickup 1 on the basis of the output of a fingertip detection sensor, a light emitting quantity controller 9 allows the light emitting element 2 to light. Next, when the person to be measured pulls off his fingertip from the blood flow pickup 1 after measurement, this state is detected by the fingertip detection sensor 4 and, therefore, the light emitting quantity controller 9 can immediately stop or limit the supply of a current to the light emitting element 2. Further, when the fingertip 10 is again inserted, the light emitting element 2 is allowed to light this time according to the procedure opposite to that when the fingertip is pulled off.

Title: Azimuth control mechanism
Inventor: FUJIE RYUICHI
IPC: G11B5/56
Filed: 1984-09-05
Abstract: PURPOSE:To improve the control effect of azimuth for each drive of a tape and the durability of an azimuth control mechanism, by securing such a constitution where an individual control screw has a contact with an abutting part according to the tape driving direction, then the control screw moves away from the abutting part when the tape driving direction is changed. CONSTITUTION:A direction switch member 23 is shifted toward an arrow head A or B and therefore a cam member 21 is turned. Then an individual azimuth control screw has a contact with an abutting part for each tape driving direction. In other words, a control screw 19 has a contact with an abutting part 25 of the member 21. While a control screw 18 abuts on an abutting part 26. Thus the individual azimuth control is possible independently for each tape driving direction. At the same time, a follower part 20 is lifted via a cam part 24 during the switch of the driving direction. Thus both screws 18 and 19 move upward apart from parts 26 and 25 together with a head fixing plate 13. In such a way, the azimuth control effect is improved for each tape driving direction. Then the durability is also improved for an azimuth control mechanism.

Title: Method of pattern matching
Inventor: MORIMOTO MASAMICHI
IPC: G06K9/62
Filed: 1985-08-23
Abstract: PURPOSE:To reduce collation processing at an enormous number of collation reference points and to speed up pattern matching process by calculating area of an image pattern included in the window frame of a standard pattern. CONSTITUTION:The case where a black cruciform pattern 72 represented by '0' exists in a white background area 71 represented by '1' and the case where a white cruciform pattern 74 exists in a black background area 73 are shown in the figure. In either case, the area of the image pattern included in the window frame of a standard pattern at each collation reference point is calculated before collation process. When the value of the area is smaller than a smaller reference value out of two predetermined reference values or larger than a larger reference value, the collation process is not made. In this way, the area in which collation reference points that require collation process can be narrowed from the whole screen to a small area 75 near the outline of the cruciform pattern, and thus, the pattern matching process can be speeded up.
