Title: Lightguide tube and manufacture thereof
Inventor: FUREDERIKU RATOBEROMANANA
IPC: G02F1/065
Filed: 1991-02-13
Abstract: PURPOSE: To inexpensively obtain an optical waveguide by constituting the waveguide of a buffer layer having a 1st refractive index(RI), a strip-like element having a 2nd RI and an waveguide layer consisting of a polymer having a 3rd RI. CONSTITUTION: A layer consisting of a material having the 2nd RI higher than the 1st RI is formed on a buffer layer 1 having the 1st RI. Then at least one strip is etched on the layer having the 2nd RI and an waveguide layer 3 consisting of a material having the 3rd RI lower than the 2nd RI is stuck to the strip 2 and the buffer layer part not coated with the strip 2. A polymer is used for the material of the waveguide layer 3. The optical waveguide can restrict light along the strip 2 having an RI fairly larger than the RI of the layer 3 consisting of the polymer. Since the polymer is used, the optical waveguide can be obtained by low cost batch manufacturing technology and its cost can be reduced.

Title: Telephone exchange with incoming call restricting function
Inventor: ORITO JUNICHI
IPC: H04Q3/58
Filed: 1989-02-21
Abstract: PURPOSE:To restrict the incoming call without needing assignment of number information or a number in duplicate from a caller subscriber by applying incoming call restriction based on password information set optionally by a called subscriber. CONSTITUTION:When a subscriber terminal equipment 1 dials a subscriber number of a subscriber terminal equipment 10 being an incoming call restriction subscriber, a central control section 4 identifiers the terminal equipment to be an incoming call restriction subscriber from the subscriber number information and connects the terminal equipment 1 and a password information reception section 6 under the control of a channel control section 8. When the connection is finished, the reception section 6 sends a message representing the input of password information to the equipment 1. When the caller subscriber sends a password, a password information collation section 5 collates the password, and when the coincidence is discriminated, the control section 4 permits the communication and connects the subscriber terminal equipments 1 and 10 via a channel switch 7. Thus, the incoming call restriction is attained with the password information only.

Meanwhile, when the rotation speed Ne of the engine is lower than the decision rotation speed Nj, in a step 116, a dash port quantity QREC is damped. When an engine temperature is low, the dash port is rapidly rendered effective, and during the cold, a dash pot amount is damped. This causes reliable prevention of the stop of an engine during running at a very low temperature and blow-up of an engine during the cold.
