Title: Network system and its communication equipment and communication method
Inventor: YOSHINO KANICHI
IPC: H04W84/12
Filed: 1994-11-16
Abstract: PURPOSE: To provide a network system, its communication equipment and communication method in which the effect of noise in existence in the environment of the receiver side is excluded. CONSTITUTION: A CPU 107 at the transmitter side uses a radio section 102 to check a radio wave environment and to select candidate of a channel available of communication and allows the radio section 102 to report a frame including candidate channel information generated by a communication controller 104 to a communication opposite party. A CPU 107 of a receiver side uses a radio section 102 to check the radio wave state of the candidate channel informed by the transmitter side and selects a channel used for communication among candidate channels and allows the radio section 102 to return a frame including selected channel information generated by a communication controller 104 to the transmitter side. Then the communication is made by using the channel selected by the receiver side.  Thus, frequent occurrence of a communication error is prevented and the repetition of re-transmission processing is prevented to prevent deteriorated throughput of the LAN system.

Title: Optical element
Inventor: TAJIMA KAZUTO
IPC: G02F1/35
Filed: 1988-11-07
Abstract: PURPOSE:To display good efficiency characteristic to an optical waveguide structure sufficiently and to enable the operation with low light power by specifying the light absorption coefficient of a material and optimizing the absorption of control light. CONSTITUTION:As for, for example, an element A, signal light 7 is branched by a branch part 11 into two waveguides and multiplexed by a multiplexing part 12 into one light beam again. Namely, this part forms a Mach-Zehnder interference system. The difference in effective optical path length between both arms of this Mach-Znhnder interference system is different by a half of the wavelength lambda2 of the signal light 7, so the light is converted to a radiation mode by the multiplexing part 12 and therefore not outputted. When signal light 8 is made incident at the same time through a directional coupling part 13, on the other hand, a heterostructure 5 absorbs the signal light lambda to vary its refractive index, so the element A generates its output. Namely, the output of the element A is the result of logical operation between the inputs 7 and 8. Consequently, the operation with the low light power is enabled.

Title: Electric discharge machine
Inventor: OKUBO YAICHI
IPC: B23H1/02
Filed: 1987-11-10
Abstract: PURPOSE:To omit a current limiting resistor further to suppress an excessive discharge current by interrupting a switching element by a fine pulse in a discharge period while decreasing a pulse width of the fine pulse in the time of abnormal discharge. CONSTITUTION:A pulse generating circuit 11 outputs a pulse specifying an electrification period and an interrupting period, and when a discriminating circuit 18 discriminates a normal discharge through a check pulse generating circuit 19, a fine pulse generating circuit 14 selects a fine pulse, set by a setter 12, turning on and off a transistor 4 through an AND circuit 15 and applying normal discharge voltage between a workpiece 1 and a machining electrode 2. Next when an abnormal discharge is detected in the discriminating circuit 18, the fine pulse generating circuit 14 selects a fine pulse of width smaller than that set in a setter 13, on-off controlling the transistor 4. Thus enabling a current limiting resistor to be eliminated, while an excessive large discharge current can be easily suppressed.

Title: Error correction circuit
Inventor: YONEDA MINORU
IPC: G11B20/18
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To reduce a circuit scale by omitting a flag memory. SOLUTION: At first an inner code is decoded. A syndrome calculation circuit 24 obtains a syndrome from input data, and an error information calculation circuit 28 obtains an error location and an error from the syndrome. Thus, an error correction execution circuit 42 corrects data of a data memory 23. On the occurrence of a correction disable error, address information denoting a storage location of the code word in the data memory 23 is stored in a missing location address register. In the case of decoding an outer code, after the address information is converted into location information in the code word, a missing location polynomial is generated. A corrected syndrome is obtained from the syndrome and the missing location polynomial and the data are corrected based on the error location and the error obtained similarly in the case of decoding the inner code.  A memory for an error flag is not required and the circuit scale is reduced.

Title: Supporting method for surface plate of lapping machine
Inventor: YAMASAKA MINORU
IPC: B24B37/12
Filed: 1988-11-11
Abstract: PURPOSE:To lower the surface plate vibration under working, to reduce the generation of chips on the hard brittle material of a ceramics, etc., and to increase the yield by providing a gap between a surface late and the surface plate supporting base excepting the surface plate fitting part and fitting the surface plate after coating the grease of a viscous body on this part.

A grease 3 of viscous body is interposed in this gap 14 and the vibration generated on the surface plate 1 during the lapping of the hard brittle material 2 of the body to be worked is absorbed by this grease 3 of a viscous body and attenuated quickly. At the same time the propagation to the surface plate 1 of the vibration generated at the lower part of the surface late support base 3 is reduced. Also, the vibration caused by the impact of the surface plate 1 and the hard brittle material 5 of the body to be worked during working is lowered as well by this grease 3. As a result, the chip generation during working caused by the surface plate 1 vibration can be prevented.
