Abstract: A multi-port optical device for transferring optical signals, or portion of optical signals, from one transmission element to another is disclosed. The inventive optical device comprises a pair of graded index lenses (103,106) having an interposed Fabry Perot etalon (109). The functionality of the device may be modified by varying the transmission characteristics of the etalon, which may be effected by varying its optical path length. In operation, the optical device utilizes the graded index lenses as image transfer lenses between transmission elements (101,102,107,108) wherein wavelength selectivity therebetween is afforded by the filtering mechanism associated with the etalon. The optical device may be used as a wavelength multiplexer or as an optical splitter. Moreover, by utilizing a piezoelectric transducer, the optical device may be made to operate as an optical switch.

Abstract: In an apparatus for forming a thin film on substrates, two substrate supporters 1 each having a recess 2 are connected by a shaft so that the recess oppose to each other, and both ends of many rod-like substrates 3 are supported on the side wall of the recess 2. Then, the substrates 3 are rotated on the side walls as the substrate supporters 1 are revolved, and the substrates shift their positions by their own weights. In this state, particles for deposition fly to the substrates from a material source, while the rod-like substrates are stirred to come at the same probability to a region where a film can be deposited. Thus, a uniform thin film is formed on the surface of every substrate. The number of the recess may be two or more. Further, a nest of substrate supporters may be used.

Abstract: The present invention is intended to improve the track recording density and track density of a magnetooptic recording medium (1) to prevent the deterioration of characteristics due to the variation of reproducing power. After recording information signals on a magnetooptic recording medium having at least a reproducing layer (3), an intermediate layer (4) and a record hold layer (5), the direction of magnetization of the reproducing layer is turned in the direction of an initializing magnetic field. The reproducing layer (3) is irradiated with a laser beam and a reproducing magnetic field is applied to the same simultaneously to heat the reproducing layer (3) in a temperature distribution so that a region remaining in an initialized state, a region to which information signals are transferred and a region magnetized in the direction of the reproducing magnetic field are formed. Magnetic signals are read from the region of the reproducing layer to which information signals have been transferred.

Abstract: Current memory cell for sampling a current (I) on a current terminal (5) during a sample interval and for applying the current (I) to the current terminal (5) during a hold interval. A first switch (S1) switches a PMOS transistor (P1) as a diode during the sample interval and as a current source during the hold interval. During the sample interval the current of the current terminal (5) is copied to the PMOS transistor (P1). During the hold interval the current of the PMOS transistor (P1) is copied to the current terminal (5). The mirroring is effected by means of two NMOS transistors (N1, N2) and one reversing switch (S2), which reverses the input and output of the current mirror circuit during the sample intervals and the hold intervals. The current mirror circuit (N1, N2) and the PMOS current source (P1) collectively behave as a current sink which is insensitive to the substrate voltages which are caused by the body effect.

Abstract: In the case of fittings which have been used up until now, insulation of the fitting has only been possible by complex manual work. Use of an intermediate piece which is seated on the flange of the neck of the fitting, consisting of a material of low thermal conductivity and of an apron enclosing the flange, provides the preconditions for uniform insulation connections. This intermediate piece delimits insulation air spaces and prevents moisture in the air from condensing on a cold fitting or loss of energy in a heating circuit. <IMAGE>
