Title: Talkie tone monitoring system
Inventor: NAKAMURA YUKIO
IPC: H04M3/22
Filed: 1981-03-02
Abstract: PURPOSE:To immediately detect a talkie trunk or an encoding device even if a fault occurs, by connecting two talkie trunks to the same tone sources and comparing their audio signal levels with each other. CONSTITUTION:A talkie tone from a talkie tone source 11 is passed through talkie trunks 12 and 22 and encoding devices 13 and 23 to be encoded into time slots 15 and 25, which are outputted to be multiplexed as the time slots of an output highway 17 in a time-division channel 16. The circuit 16, on the other hand, connects the time slots 15 and 25 to the time slots 19 and 29 of an output highway 27 semipermanently. The highway 27 is connected to a talkie tone monitoring device 28, which compares two audio signals inputted from the time slots 19 and 29 and, when their level difference goes beyond a permissible range, judges that the trunks 12 and 22, or encoding devices 13 and 23 have a fault. Thus, the talkie tone is monitored all the time, so any fault is found immediately.

Filed: 1979-03-12
Abstract: PURPOSE:To realize both a small size and high performance by using the central conductor plate for the strip line terminal and then providing the tab to the conductor plate to use it for the load capacity. CONSTITUTION:Ferrite plates 13 (13a, 13b) and central conductors 14 (14a-14c) are held between permanent magnet 8 and soft magnetic substance plate 16. Magnet 8 functions the upper cover directly, and plate 16 doubles the earth conductor. Thus the capacity is caused between magnet 8 and plate 16. The tabs 21 (21a, 21b) are installed to central earth plate 14 to control the capacity. As a result, the optimum load capacity is realized to secure the high performance as well as omit the external capacity. Furthermore, the whole structure can be unified into a compact form. Both the unevenness and the shape are optional for tabs 21 according to each earth conductor.

Title: Powder dispersing machine
Inventor: YAMADA YUKIYOSHI
IPC: B07B11/06
Filed: 1991-02-22
Abstract: PURPOSE:To efficiently disperse a fine powder by the ejector action with a small-sized device by discharging a powder contg. flocculated grains from a cylindrical or annular narrow passage and a high-speed air flow from around the discharge port. CONSTITUTION:The outer peripheral wall of a nozzle 20 gradually decreases in diameter toward the lower part, and an annular small passage is formed between a body 11 and a tapered cylindrical part 12a. Accordingly, an annular opening surrounding the opening of the nozzle 20 is formed at the lower end of the nozzle 20. The annular opening is used as the blowoff port of the air flow supplied to a cavity 19 from the port 21 of the body 11, i.e., a high-speed air flow blowoff port producing an ejector effect. A powder passage connecting the lower opening 20a and an upper hopper part 22 is provided in the nozzle 20. A powder is appropriately supplied to the hopper part 22 from a feeder. As a result, the powder is efficiently dispersed by this small-sized device, and the deposition of the granular body on the side face of the outer wall is prevented.

Title: Abnormality detecting and disposing device in machine tool
Inventor: URABE HIROKUNI
IPC: G01M99/00
Filed: 1980-03-06
Abstract: PURPOSE:To detect abnormal vibrations by installing a vibration detector to a wheel spindle stock. CONSTITUTION:When a grinding wheel makes abnormal contact with the projecting end face etc. of the work piece, relatively high frequencies are obtained in the piezoelectric type vibration detector A on a wheel spindle stock and these are taken out as a binary signal by a comparator D. In ordinary grinding, the vibration level is small and is not therefore taken out as an abnormal signal. A retrigger type monostable multi F removes high-frequency components such as electrical noise by including a short period pulse in the next pulse and counting this as one and inputs these to a preset counter H. A monostable multi I applies a reset signal to the preset counter H wnen the next pulse does not come in within a certain time after the end of the pulse. When reduced to a counter preset value, the preset counter H applies a signal to an alarm flip-flop L .

Title: Recording disk reproducing device
Inventor: KONDO MASAKI
IPC: G11B33/08
Filed: 1987-02-10
Abstract: PURPOSE:To improve a vibration proofing effect without using any rubber by providing a 1st sliding member, 2nd sliding member, pressing member and an elastic member between a chassis and facing case body. CONSTITUTION:An external vibration is propagated to the 2nd sliding member 4 through a facing case body 2 and the vibrations in Z1, Z2 directions become a simple harmonic motion by a coil spring 8. The simple harmonic motion propagated to a chassis 1 is propagated to the pressing member 5 located between the 1st sliding member 3 and 2nd sliding member 4 through the 1st sliding member 3. A press member 5 is brought into contact with pressing force between the 1st and 2nd sliding members 3, 4 and in the case of its vibration in Z1, Z2 directions, the friction force in reverse direction to the vibration direction works on the press member 5, 1st and 2nd sliding members 3, 4 at all times. A vibration proofing can be effected by attenuating the simple harmonic motion by using this friction force and the vibration proofing effect can be improved.

Title: Method of disposing exhaust gas
Inventor: ASATOU TAKAYASU
IPC: B01D53/60
Filed: 1979-03-12
Abstract: PURPOSE: To prevent substances from adhering to a catalyst layer and dispose of combustion exhaust gas at low cost in a process of reducing the exhaust gas in contact with ammonia, by adding ammonia, collecting dusts and thereafter denitrificating the gas by a catalyst which is low in SO 2 -oxidizing power.  
     CONSTITUTION: Exhaust gas from a coal combusion boiler or the like, which contains a large amount of dusts and contains nitrogen oxides, oxygen and sulfur oxides, is reduced in contact with ammonia. The ammonia is added to the exhaust gas having a low temperature of 100W300°C, thereby changing the sulfuric anhydride in the exhaust gas into ammonium sulfate. After the exhaust gas is removed of the ammonium sulfate and the dusts by an electric dust collector, the gas is denitrificated by a catalyst which has a denitrification property at 200W300°C and is very low in activity to change SO 2  into SO 3 . The ammonium sulfate and the dusts are thus prevented from adhering to the catalyst layer. This results in stably disposing of the exhaust gas at low cost for a long time.

Title: Production of inulooligosaccharide product small in content of glucose, fructose and sucrose
Inventor: FURITSUTSU HAINTSU
IPC: C07H3/06
Filed: 1991-01-30
Abstract: The invention relates to a process which starts from inulin-containing plant material and produces an inulooligosaccharide product which is low in glucose, fructose and sucrose. This is achieved by subjecting the inulin-containing plant material directly after comminution and pasteurisation to an enzymatic treatment with endo-inulinase and choosing conditions for this which minimise the glucose, fructose and sucrose contents, and then removing interfering glucose and fructose by chromatography. The sucrose can be removed by adding  alpha -glucosidase, especially before the chromatography. Selected conditions for the enzymatic treatment are: maintaining the pH constant between 5.0 and 5.6, and the temperature between 50 and 60 DEG C and using 1.8 to 2.4 enzyme units of endo-inulinase per gram of inulin.
