Title: Optical waveguide and its manufacture
Inventor: ARAKAWA TOMIYUKI
IPC: G02B6/122
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To reduce the connection loss of a connection between the core of an optical waveguide and a circular or elliptical optical waveguide layer. SOLUTION: A lower cladding layer 18 provided on a substrate 12 has a valley-shaped hollow 38 along a groove 36 on its surface, by providing the groove 36 on the surface of the substrate 12 of an optical waveguide 28. Furthermore, the core in provided along the valley-shaped hollow 38 and then the core lower part (part of core 22 facing lower clad layer 18) is a curved surface on which the shape of the hollow is reflected. Consequently, the connection loss due to the difference in shape between the core 22 of the optical waveguide 28 and the circular or elliptical optical waveguide layer connected to the optical waveguide 28 is reduced. When an optical fiber 48 is connected, the groove 36 is usable as an optical fiber mount groove, thus the core 22 of the optical waveguide 28 and the core 50 of the optical fiber 48 are positioned self-alignedly to reduce the connection loss.

Title: Liquid crystal display element
Inventor: SHIBUYA MASAMICHI
IPC: G02F1/13
Filed: 1978-11-10
Abstract: PURPOSE: To surely prevent the leakage of liquid crystal and achieve the improvement in reliability by forming the sealing part of the liquid crystal sealing port side on the side inner by the specified distance from the cutting position and sealing the liquid crystal sealing port with an organic adhesive agent.  
     CONSTITUTION: The sealing material 3 on the liquid crystal sealing part 4a side of the liquid crystal cell 4 which is cut and parted to individual cells is secured and formed on the side inner by d=0.05W0.5mm apart from the end faces of an upper plate 8 and lower plate 9. This liquid crystal sealing part 4a is bonded and set by an organic adhesive agent 10 such as, e.g. epoxy resin, after liquid crystal 6 has been sealed into the liquid crystal cell 4. With this constitution, the organic adhesive agent 10 readily infiltrates into the spacing of about 10μm between the upper plate 8 and lower plate 9 owing to capillarity and closes the portions of the frit sealing agent 3 as well, thus the leakage of the liquid crystal 6 may be perfectly prevented.

Filed: 1983-07-28
Abstract: PURPOSE:To check errors of both medium layers for data and servo purposes respectively by providing two transducers to record low frequency servo information and high frequency information then separating reproducing outputs of those transducers through filters. CONSTITUTION:A servo signal is recorded with a low frequency to a track (n) from an amplifier 14 via a servo transducer 24 having a large gap length. Then a data transducer 25 having a small gap length is shifted to the track (n) to record the data information with a high recording frequency on the track (n) via an amplifier 6. Then both information are simultaneously reproduced and amplified by the transducer 25 and separated into the data information and the servo information through an HPF15 and an LPF20, respectively. These separated signals are compared with error comparison levels of circuits 16 and 21. Then error detecting parts 18 and 23 detect defective parts, respectively. The error signals are switched between the data and servo signals by a switching circuit 19 and supplied to a control part 12.

IPC: H04N1/32
Filed: 1990-05-30
Abstract: PURPOSE:To reduce the probability of leakage of picture information by using transmission speeds more than types of coding/decoding systems so as to cipher picture information substantially. CONSTITUTION:A transmission speed set to a MODEM 4 depends on a system control section 8 and a cryptographic table is stored in a RAM 10, in which plural kinds of transmission speeds and cryptographic parameters are in cross reference. Moreover, a program activating a system control section 8 having a function of controlling each component according to a scheduled program is stored in a ROM 9. Then an actual transmission speed is not added in a protocol control signal and a data representing the transmission speed added to the protocol control signal is differentiated from the actual transmission speed according to the prescribed method. Thus, in the case of interception caused, an interception equipment cannot identify the transmission speed of the picture information sent from a transmission station.
