Abstract: PURPOSE:To minimize dividing loss and to construct an efficient dedicated network by executing the channel allocation of an arbitrary high speed side circuit corresponding to a call quantity generated within a exchange. CONSTITUTION:When a telephone system 120 transmits to a dedicated network, a controller 11 of an exchange selects a free circuit 101 from voice circuits, transmits a low speed side circuit number 201 to a controller 21 of a multiplexing device 2 through a control signal path 5, selects and allocates a free channel 601 of a high speed side circuit and transmits to a controller 71 of a multiplexing device 7 placed opposite each other through a control signal path 9. The controller 71 allocates the channel 601 of the high speed side circuit to a low speed side circuit 701 based on received information. When allocation completion is returned to the controller 11 of the exchange 1, the telephone system 120 and the selected circuit 101 are connected. When talking is ended and the low speed side circuit becomes free, the channel of the corresponding high speed side circuit is released and is made free.

Title: Magnetic disk
Inventor: MINAMI TSUTOMU
IPC: G11B5/725
Filed: 1988-12-07
Abstract: PURPOSE:To prevent adhesion of a head slider by forming a coating film of zirconium oxide or a mixture of silicon oxide and zirconium oxide as a protective film of a magnetic disk. CONSTITUTION:A substrate 10 consists of an Al-Mg alloy substrate 1 and a Ni-P plating film as a base hardened layer 2. A magnetic layer 3 is a Co-Ni film formed by sputtering, on which an about 500Angstrom thick coating film of zirconium oxide or a mixture of silicon oxide and zirconium oxide is provided as the protective film 4. Further, an about 10Angstrom  thick lubricating film 5 of fluorine polar lubricant is applied. By this constitution, the protective film 4 of zirconium oxide or the mixture of silicon oxide and zirconium oxide causes less adsorption of water compared to a silicon oxide coating film, so that the disk is almost free from coagulation of water when the head slider contacts to the disk. Consequently, adhesion of the head slider due to water if existing between the slider and the disk is prevented. As zirconium oxide supports the lubricant well, the lubricating film on the surface hardly peels off, which improves wear resistance of the disk.

Title: Light-light switch
Inventor: ITO KEN
IPC: G02F1/35
Filed: 1989-11-29
Abstract: PURPOSE:To control the signal light with switching light by providing a diffraction grating forming element with the refractive index reversibly changed in accordance with the incident light intensity and a means for projecting switching light to form an interference pattern in the element and detecting the signal light projected on the element. CONSTITUTION:When the switching light 3 is projected, an interference pattern is formed on the diffraction grating forming element 1. Consequently, the refractive index is partially changed in accordance with the interference pattern, and an diffraction grating is formed by the diffractive index distribution. Accordingly, the signal light 4 projected on the element 1 is diffracted as shown by the dotted line 6 and detected by a slit 5. When the switching light 3 is turned off, the signal light 4 is not diffused but transmitted through the element 1 as shown by the full line 7 and not detected by the slit 5. If a slit is also provided at the position of the full line 7, the signal light 4 is switched. Consequently, the signal light 4 is accurately switched, and the light signal is directly controlled by the light signal.
