Title: Atm communication network
Inventor: YAMANAKA NAOAKI
IPC: H04L47/722
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To transfer a cell efficiently without causing congestion in traffic of a client server type by allowing an ATM communication network to conduct control while utilizing a feature of the client server model. SOLUTION: A client provides an operation and maintenance OAM cell that describes available rate information for transmission/reception to a head of a series of cells. An ATM switch estimates a band through which a series of the cells can be transmitted without causing congestion and writes the information to the OAM cell. A server sets a route and a transmission on rate at which a series of the cells are transferred to the client without causing congestion according to band information and data size information from OAM cells arrived from a plurality of routes within a prescribed time and provides an OAM cell to which this transmission rate is written to the head and the tail end of a series of the cells.  The ATM switch reserves the band according to the transmission rate information in the OAM cell at the head of a series of the cells and releases the band according to the transmission on rate information of the OAM cell at the tail end.

Abstract: PURPOSE:To obtain a simple, compact and highly efficient device with a large speed reduction ratio without providing a separate revolving protector of a worm by a structure wherein a ball screw type actuator is combined with a rack-and-pinion type steering device. CONSTITUTION:A member with a friction plate 24 is integrally mounted through a leaf spring 34 to the nut 25 of a ball screw. When an electromagnet coil 35 is turned ON, the friction plate 24 engages with the other friction plate 23 against the force of the spring 34 so that the output shaft 10 of an electric motor coupled with spline mechanism to a member provided with the friction plate 23 engages with a nut 25. When the coil 35 is turned OFF, the friction plates 23 and 24 separate from each other and consequently no output of the electric motor 8 is transmitted to the nut 25. In spite of a rack shaft 7 being applied turning reaction through conversion of the output of the electric motor 8 into an axial movement of the rack shaft 7, no revolving of the rack shaft 7 results by means of the reaction developed in the engagement part between a pinion gear 16 and a rack gear 17 and in a pressure pad 18.

Title: Optical recorder for magneto-optical recording including erasable device and magneto-optical recorder
Inventor: FURETSUDO DABURIYU SUPONGU
IPC: G11B11/105
Filed: 1988-06-01
Abstract: A magneto-optical recording disc 10 has an erasable magneto-optical recording structure 14 for recording the intensity modulation of the incident radiation 12 in the presence of a magnetic field. The radiation impinges on an incidence side 13 of the recording disc. The magneto-optical recording structure 14 is applied on a side of a substrate 16 facing away from the incidence side. The material of the substrate has excellent load-bearing characteristics, chosen without regard to the optical transmission characteristics of the material. A supporting structure 18 of coaxial sealing rings 19-19 keeps the window at a distance from the side of the magneto-optical recording structure which is facing the incidence side 13 of the recording disc. Between the window and the recording structure there is an air gap 22. The window is optically transparent and has a minimal birefringence, so that the radiation incident on the incidence side 13 of the recording disc 10 is passed on through the window with minimal optical delay. As a result, the difference of the effective Kerr angle of the polarisation rotation, corresponding to the different directions, namely upwards or downwards, of the magnetisation on the magnetooptical recording layer 15 of the recording structure 14, is primarily in relation to the recorded data and not dependent on the optical delay through the window. In the case of further exemplary embodiments of recording discs, the air gap is filled with a transparent adhesive and, instead of the magnetic recording structure, an appropriately adapted interference multi-layer structure is used, in order to intensify and optimise the difference of the effective Kerr angle of the polarisation rotation according to the different directions of magnetisation on the magneto-optical recording layer of the multi-layer structure. In the case of one of these embodiments, two such recording discs are arranged with their substrates back to back or share a common substrate, in order to form a double-sided magnetooptical recording disc.

Abstract: PURPOSE:To surely recognize the shape of an image pickup object by comparing corresponding picture elements of the read signal from a template memory and a binarization signal with each other. CONSTITUTION:The picture signal of character T is converted to a binarization signal by a binarization circuit with respect to each picture element. AND between picture elements of the binarization signal and the template read signal constituting an expanded template 3b is operated, and a number (m) of picture elements in the part where AND is '1' is counted by a counter 5a. AND between picture elements of the binarization signal and the template read signal constituting a reduced template 3c is operated by an AND 4b, and a number (n) of picture elements in the part where AND is '1' is counted by a counter 5b. In this case, the number (m) is always equal to the number of picture elements whose parts of the binarization signal are '1', and the number (n) is always equal to the number of picture elements whose part of the template read signal constituting the reduced template 3c are '1'. Consequently, it is judged by a decider 6 that the image pickup object is matched to a template if this template satisfying these relations exists.

Filed: 1979-10-16
Abstract: PURPOSE:To improve the efficiency of copying work by forming again the latent images of a latent image carrying body according to the length of the stop time when the copying apparatus has stopped while it is forming the copying images continuously. CONSTITUTION:If in a copying apparatus having a capacity of obtaining 100 sheets of copied images from a primay latent image the primary latent image is formed again every time when trouble has occured at the 25th sheet and 50th sheet, it becomes equivalent to an apparatus which performs 100 sheets of copying through formation of the primary latent images of substantially three times. Thereupon, if any trouble occurs during continuous copying, whether the primary latent image is reusable or not is judged by electric means such as timer according to the processing time for the trouble. If it is judged to be usable, the primary latent image is reused and if it is judged unusable, the primary latent image is formed again, after which the copying operation for the remaining sheet number is carried out. In this way, the efficiency of the copying work may be improved.

Abstract: PURPOSE:To form the shape of a channel with excellent reproducibility by conducting mesa etching before buried growth by the combination of anisotropic dry etching and wet etching having no anisotropy. CONSTITUTION:A wafer 11 to which a double hetero-epitaxy is grown previously is patterned by a photo-resist 12. A channel 13 is shaped through dry etching under conditions of intense anisotropy by using carbon tetrachloride. According to the dry etching, the channel 13 having a type close to a well type specified by mask width can be formed because of intense anisotropy, but a damaged layer 14 is shaped. As a result, the layer 14 is removed through wet etching having no anisotropy. Consequently, the shape of a channel 15 formed is kept constant at all times. When buried growth is conducted to the substrate, the reproducibility of a buried shape is improved extremely because the form of the channel 15 is kept constant.
