Title: Data transmitter
Inventor: KATSUHARA JIRO
IPC: H04L12/00
Filed: 1985-05-20
Abstract: PURPOSE:To confirm the absence of a fault in its own station, other stations and transmission lines and to confirm that the communication with other stations is normal by providing an information part referred to as 'transmission number' in a frame used in performing data communication between stations and allowing each station to transmit and receive mutually the said transmission number. CONSTITUTION:In sending information representing the right of sending or a data from a station (STN) 3, a transmission counter is incremented by 1 and set to a transmission number position. The transmission number of each STN corresponding to a number among transmission numbers received for far in frame constitution is sent by a transmission number sending means together with a data or the right of transmission. The other station receiving them uses a supervisory means to discriminate it as the normal communication with the STN 3 when the transmission number sent precedingly from its own station with the transmission number of its own station from the STN 3 are identical and to discriminate it that the communication is not normal when the numbers differ. Thus, the fault of its own station, between stations and of a transmission line is discriminated easily with the simple processing.

Title: Prevention of blow hole of sintered hard alloy
Inventor: HIROSE KAKUJI
IPC: C22C29/08
Filed: 1983-06-15
Abstract: PURPOSE:To prevent blistering owing to blow holes by adding the oxide of a ferrous metal and carbon to a sintered hard alloy consisting of the carbide and nitride powder of the IIIa, IVA, Va groups and ferrous metallic powder as a binding metal. CONSTITUTION:The oxide of a ferrous metal is added at 0.5-5wt% to a sintered hard alloy consisting of powder of >=1 kind among the carbinde and nitride of the IIIa, IVa and Va groups of periodic law table and ferrous metallic powder as a binding metal. C of the amt. enough to reduce the above-mentioned oxide is further added thereto. Then the intentional generation of gas from the inside and the generation of a liquid phase from the entire part of the molding at a low temp. are made possible. If the ferrous metal is Co, CoO is brittle and intrudes among the flat particles of Co having malleability in the process in which CaO is finely ground with a wet type ball mill, thereby preventing the fluocculation of the Co particles and at the same time the C intrudes among these particles as well. As a result, the Co powder and the C powder are dispersed and the CO is generated in each part.

Title: Light wavelength converting device
Inventor: INOUE YASUSHI
IPC: H04B10/299
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To enable light wavelength conversion irrelevantly to the polarization direction of an inputted light signal (without polarization dependency). SOLUTION: Continuous light of wavelength #1cw and a light signal of wavelength λsig are both inputted to a semiconductor optical amplifier 1 whose gain characteristics do not depend upon the polarization direction and the continuous light of wavelength λcw is modulated with the light signal of wavelength. The light signal of wavelength λcw outputted by this semiconductor optical amplifier 1 is impressed to a semiconductor laser oscillator 2 which is oscillating and has its wavelength converted. At this time, the polarization directions of the continuous light of wavelength λcw and the light signal of wavelength λcw outputted from the semiconductor optical amplifier 1 are held by a polarization holding optical fiber and the polarization directions match the optimum polarization direction of the semiconductor laser oscillator 2. Consequently, the wavelength of the light signal can be converted without reference to the polarization direction of the inputted light signal.

Title: Rotary equipment and motor or its bearing component
Inventor: ARAI KATSUTOSHI
IPC: F16C32/00
Filed: 1990-04-25
Abstract: PURPOSE:To enhance support stiffness of a rotating body, to attain positioning with high precision, to ensure fluid lubrication and to prevent scattering of magnetic fluid by arranging permanent magnets on a shaft, magnetizing the magnetic fluid on a radial bearing slide face to support the fluid on the shaft securely and forming a thrust bearing with the permanent magnets arranged opposite to each other. CONSTITUTION:Since permanent magnets 4a, 4b are arranged in a hollow of a shaft 1 opposite to a slide face of radial bearing 2a, 2b, magnetic fluid 3a(3b) of the sliding face of the bearings 2a, 2b is magnetized and supported on the surface of the shaft strongly. Thus, sure fluid lubrication is ensured and the fluid is not scattered by rotation of the shaft. Moreover, thrust bearing components 5a, 5b, 15a, 15b utilize the magnetic force of the permanent magnets to balance the magnetic forces of two sets of permanent magnets 5a, 5b, 15a, 15b to support the shaft 1 in noncontact state. Thus, the gap between opposed faces of the magnets is made narrow to increase the magnetic force thereby position the shaft 1 in the axial direction with high precision. Thus, flowout or scattering of the magnetic fluid is not caused and the smooth and highly precise rotation is maintained.
