Title: Communication system
Inventor: OZAKI TOMOYA
IPC: G06F21/12
Filed: 1991-05-23
Abstract: PURPOSE:To limit a geographical and a spatial positional range in which a specific data is used by allowing a communication node to discriminate the acceptability of data transit. CONSTITUTION:A server 302 supplies a data to a communication node 303 and a client 301. In this case, a transit enable radio node ID is read from an ID management table with respect to the supplied data and the ID is added to the data to be fed to generate the data to be sent. When the communication node 303 detects a communication data from the server 302 at a communication unit 425, at first the communication data is received. Then an ID of its own radio node is read from a storage device 423 and when the same node as that of its own radio node is in existence in transit enable radio nodes ID in the communication data to be received, the transit permission of the communication data is sent. Then a radio communication unit 424 sends a communication data to the client 301. Thus, the position range is limited and leakage of secrecy relating to the data to an external device is avoided.

Filed: 1990-05-08
Abstract: PURPOSE:To reduce the fitting space for the electric alarming horn which has two resonance systems by equipping the electric alarming horn, used for a vehicle, etc., with a high and low frequency common trumpet part where a high and a low frequency resonance pipe communicate with each other and increase gradually in sound channel sectional area. CONSTITUTION:When driving parts 14a and 14b are supplied with electric power, currents flow to electromagnetic coils 9a and 9b and diaphragms 5a and 5b vibrate themselves. Sounds are generated in sound source chambers 6a and 6b between a trumpet 1 and the diaphragms and guided to resonance parts 3a and 3b through throat holes 2a and 2b to cause a resonance phenomenon at a specific frequency determined by the overall length of the trumpet, and harmonic components are generated and amplified acoustically. The trumpet part 4 radiates the harmonic components into the atmosphere without any loss and the resonance parts 3a and 3b for the high frequency sound and low frequency sound are linked with the high and low frequency common trumpet part 4, so the fitting space is reducible.

Title: Trouble-free computer system, its internal circuit and error detecting/correcting system
Inventor: KANEKAWA NOBUYASU
IPC: G06F15/177
Filed: 1988-05-16
Abstract: PURPOSE:To enhance the trouble-free ability and reliability of the title system by securing the normal action of the system when one or more of sub-systems constituting the system are normal. CONSTITUTION:In diagnostic functions 2-1-2-N. a processing result or a processing intermediate result and a self diagnosis result are exchanged among sub-systems 1-1-1-N, and they are comparatively judged. Diagnostic functions 3-1-3-N diagnose the normality of the actions of the diagnostic functions 2-1-2-N. A deciding circuit 10 executes the expanded majority decision of diagnosis results 4-1-4-N by referring to diganosis results 5-1-5-N. Even when the number of inputs diagnosed to be normal by the diagnosis results 5-1-5-N does not exceed the majority, by outputting the inputs diagnosed to be normal as signals overlapped by plural ones, the output of the normal sub-system can be produced to the majority decision result.

Title: Organicmetal vapor growth method and susceptor therein used
Inventor: IKEDA MASAKIYO
IPC: H01L21/205
Filed: 1990-05-10
Abstract: PURPOSE:To increase the number of vapor growth of organicmetal remarkably to reduce the manufacturing cost and to increase an yield of the product by using such a susceptor that has the surface roughness of silicon carbide installed on its surface within the specific range when developing a III-V compound semiconductor thin film on a substrate by the pyrolysis of organometallic gas and a hydride of the V group. CONSTITUTION:A susceptor 1 is made of carbon 2 and SiC 3 which is installed on the surface. The surface roughness of SiC is ranged from 10 to 100mum. In the case that the surface roughness of SiC is below 10mum, a contact area between a GaAs crystal developed on the surface of SiC and SiC is small, thus getting a bad adhesion. In the case that the surface roughness of SiC is over 100mum, the adhesion between a substrate and the susceptor gets bad, with the result of a bad heat transmission to the substrate. The more desirable range of the surface roughness of SiC is from 20 to 30mum.

Title: Opening and closing device of heating furnace
Inventor: IWATANI AKIYUKI
IPC: C21D1/74
Filed: 1979-09-14
Abstract: PURPOSE: To prevent out-of-furnace leakage of in-furnace atmosphere gas by inserting inner  cylinders from both ends to an outer cylinder which is freely rotatable to the front and rear ends  of a heating furnace for steel materials etc. and is provided with the slits permitting the passage  of the steel materials to be heated and making the same freely slidable in the axial direction of  the outer cylinder.  
     CONSTITUTION: At the time of heating the steel material 1 to be heated in a heating furnace 3,  the steel material 1 is fed into the furnace with hearth rolls 2. Projections 10 are protrusively  provided from the hearth and top at the front end of the heating furnace 3 (the same holds true  of the rear end) and an outside cylinder 11 is supported freely rotatably by these. Slits 12 corresponding to the passage way of the steel material 1 are formed to the outer cylinder 11. Inner  cylinders 13a, 13b are inserted to the outer cylinder respectively from both ends and are made  mutually approachable and detachable in the axial direction within the outer cylinder 11. The  steel material 1 enters the inside of the heating furnace by passing the slits 12 of the outer cylinder  11. Since the inner cylinders 13a, 13b are held inserted to the outer cylinder from both ends, the  width W of the slits 12 may be set to match the width of the steel material 1; therefore, the  amount of the leakage of atmosphere gas such as N 2  in the heating furnace to outside the furnace  is extremely small and there are less losses of the atmosphere gas and heat.
