Title: Two-layer ice cream and production thereof
Inventor: SHIMIZU HIROYASU
IPC: A23G9/04
Filed: 1989-04-04
Abstract: PURPOSE:To obtain a two-layer ice cream adapted to mass production in a factory without requiring complicated processes by filling a sauce having a specific viscosity in a container, flattening the sauce surface and then filling an ice cream.mix in a space thereon. CONSTITUTION:A sauce having 4000-10000cP viscosity is filled in a container and the surface thereof is then flattened. An ice cream.mix is subsequently filled in a space thereon to afford the objective two-layer ice cream. The reason why the upper limit of the viscosity of the above-mentioned sauce is set at 10000cP is that the sauce having a higher viscosity cannot be extruded from a filling nozzle or problems, such as running, are caused if the extrusion can be carried out. The reason why the lower limit of the viscosity is set at 4000cP is as follows. If a sauce having <4000cP viscosity is filled, the filled sauce will not be a conical shape and the sauce top surface is flattened, eliminating the need for spraying of air, instead, creating the need for increasing the temperature of the sauce by a method for blowing nitrogen gas thereon, etc., and enhancing the viscosity to >=4000cP.

Title: Connection structure for optical fiber
Inventor: ASHIKAWA SHIGEAKI
IPC: G02B6/26
Filed: 1988-04-08
Abstract: PURPOSE:To remove limits from a transmission band by interposing a step index type optical fiber between a single mode optical fiber and a multimode optical fiber formed by a CVD manufacturing method when connecting both optical fibers together. CONSTITUTION:The step index type optical fiber 4 is interposed between the single mode optical fiber 1 and the CVD multimode optical fiber as a transmission line. Consequently, the light projected from the single mode optical fiber is converted to a mode wherein it has a nearly uniform distribution over the entire range of the diameter of the core in the step index type optical fiber and then is made incident on the CVD multimode optical fiber. Consequently, the multimode optical fiber is excited almost uniformly over the entire area of its core diameter and the influence of a dip in refractive index nearby the core center part is nearly ignored. Consequently, when the single mode optical fiber and CVD multimode optical fiber are connected mutually, deterioration in transmission waveform due to the limitation of the transmission band is eliminated.
