Title: Retroreflecting body
Inventor: OGI HISAO
IPC: G02B5/128
Filed: 1985-09-12
Abstract: PURPOSE:To provide a retroreflecting body of transparent ball exposed type which has aesthetic appearance by colors without coloring transparent balls by providing at least one coloring layer continuously extending between the side parts of the transparent balls in the retroreflecting body. CONSTITUTION:A tentative adhesive agent is coated to a polyester base film and after the colorless transparent glass bodies 14 are sprayed thereon, the coating is heat-treated to tentatively adhere the transparent balls in the state of embedding the balls about half spheres or below into the tentative adhesive agent. A transparent or opaque coloring soln. is then poured from the side where the transparent balls are exposed into the spacings between the side parts of the transparent balls and is dried, by which the coloring layer 20 of the transparent or opaque color is formed between the side parts of the transparent balls. Aluminum is thereafter deposited by evaporation on the coloring layer and the exposed surfaces of the transparent balls to form a reflection layer 12; thereafter the layer 12 is adhered via an adequate adhesive agent layer 11 to a base 10. The tentative adhesive agent is stripped together with the polyester base is succession thereto, by which the retroreflecting body of the transparent ball exposed type is obtd.

Title: Dressing food
Inventor: HIRAYAMA SHUJI
IPC: A23L27/60
Filed: 1984-09-28
Abstract: PURPOSE:To prepare a dressing food having bright yellow color tone and storable for a long period without causing discoloration and fading, by using the juice of citrus depressa as a colorant. CONSTITUTION:The objective dressing food contains about 12-42wt% citrus depressa juice based on the final product. A red-colored dressing food containing tomato ketchup and a reddish orange-colored dressing food containing paprika oil, etc. are already known, however, these dressing foods having warm color tone exhibit remarkable discoloration or fading after the storage of e.g. 3-5 months to cause the degradation of the commercial value. A dressing food having bright yellow color tone free from the above defects can be prepared by using citrus depressa as a colorant. Since the colorant is a natural substance, the obtained food suits the recent tendency toward natural foods.

Filed: 1983-10-28
Abstract: PURPOSE:To form continuously a lot of pulse patterns for a required time only by setting plural optional pulse patterns and their generating time to the 1st and 2nd memories to transmit an optional pulse for an optional time only. CONSTITUTION:The data of a pulse pattern A and its generating time (a) is read from the 1st and 2nd memories 2, 3.

Filed: 1988-08-16
Abstract: PURPOSE:To obtain a reproduced recording picture and a communication time in matching with the transmission original by varying the read speed in response to fine or coarse document in an original with a set marker. CONSTITUTION:A read section 1 outputs a read picture signal 1a of a marker 3a and a marker detection section 4 identifies a signal of the marker 3a included in the picture signal 1a from a reference value and outputs a fine line density control signal 4a. The read section 1 decreases the speed of the main scanning and subscanning by a command of the signal 4a and when the marker 3b is read the speed of the main scanning and subscanning is increased by using a coarse line density signal 4a from a marker detection section. A communication control section 6 adds fine/coarse line density information to a picture signal and sends the result to a line 7. A reception recording section 8 controls the speed of the main scanning and subscanning according to the fine/coarse line density information received from the line 7. Thus, the reproduced recording picture and communication time in matching with the transmission original is obtained.
