Title: Muting circuit
Inventor: SATOU KENICHI
IPC: H04L27/227
Filed: 1983-07-19
Abstract: PURPOSE:To cut off sound signals by obtaining precise muting action signals by detecting the receiving conditions in 4 phase DPSK demodulation circuit, in the voice digital stransmitter using carriers. CONSTITUTION:The 4 phase DPSK signals from an input terminal 16 are inputted in a demodulation circuit 18, also in a carrier regenerative circuit 41, and two kinds of carriers with a phase of pi/62 or -pi/2 will generate. After these carriers are multiplied with input signals by multiplying machines 34, 37, carrier components are removed by filters 35, 38 changed into 2-value signals, and digital signals are regenerated. The digital signals are restored to voice signals by a D/A conversion circuit via a decoder 19, and inputted via muting switches 30 to 33. The signals outputted from the low-pass filter 38 are identified in amplitude by an amplitude discrimination circuit 43, the signals outputted through an integrator 44 represent changes in demodulation signals amplitude generated by phase distortion. Under this condition, errors occur and therefore the muting switches 30 to 33 are turned off because of making a big noise.

Title: Reel device for rope
Inventor: TAKASAKI TADAO
IPC: B65H75/44
Filed: 1989-05-25
Abstract: PURPOSE:To prevent a load of a fixed value or more on a drive machine, while giving fixed tension to a rope, and to contrive the reduction in size and weight by mounting a pair of magnets between a reel and the drive machine through a space and utilizing magnetic force of the magnets so as to transmit torque. CONSTITUTION:In a rope reel device, when it is placed in a brake action condition by stopping a motor 17, a stop condition of a reel 15 is held through magnets 18, 19. Also in the case of rewinding a wire rope 3, when the magnet 18 is rotated by the motor 17, the reel 15 is rotated by magnetic force between the magnet 18 and the magnet 19 in a side of the reel 15, and the rope 3, while it is given predetermined tension in accordance with attracting force between the magnets 18, 19, is rewound on the reel 15. In this rewinding, when a large load is applied to the rope 3 due to a certain cause, resistance of the reel 15 increases, and when the resistance exceeds the attracting force between the magnets 18, 19, a slip is generated between both magnets. Consequently, no large load is applied to the motor 17, and its operation can be continued without causing damage of seizure or the like.

IPC: F01N3/08
Filed: 1995-05-02
Abstract: PURPOSE: To provide a clarification device with means for controlling temperature of a catalyst device within a proper temperature region in which clarification ratio of nitrogen oxides becomes maximum in order to maintain a temperature within the proper temperature region for long hours and improve the clarification ratio in accordance with a temperature and temperature change of the catalyst device. CONSTITUTION: Amounts of HC and NOx in exhaust gas are calculated by detecting signals from an exhaust temperature sensor 31 and a rotational sensor 32. A necessary amount of HC for clarifying NOx is calculated based on the amount of NOx and the temperature obtained from the exhaust temperature sensor 31. Necessary amount of supplied gas oil is calculated by subtracting the calculated HC amount in exhaust gas. For a predetermined time, a temperature gradient is calculated by memorizing an exhaust gas temperature. If the temperature gradient is positive, the exhaust gas temperature is going up. If the exhaust gas temperature is judged as going up and the exhaust gas temperature is lower than the predetermined temperature, an amount of supplied gas oil is adjusted to be increased in accordance with a positive temperature gradient in order to increase a catalyst temperature rapidly.  If the exhaust gas temperature is lower than the predetermined temperature and the temperature gradient is not positive, an amount of supplied oil gas is not changed and oil gas is supplied into an exhaust pipe 45.

Title: Method for relieving residual tensile stress of weld zone of pipe joint
Inventor: MATSUMOTO TAKERU
IPC: B23K31/00
Filed: 1980-09-26
Abstract: PURPOSE: To reduce the residual tensile stress of the weld zone of piping surely by a simple method by heating the part near the weld zone of the pipe joint uniformly then cooling the surface desired to relieve residual tensile stress.  
     CONSTITUTION: A gaseous flame or a high frequency heater is used as a heating means, and the neighborhood of the part to relieve residual stress is heated, after which the side desired to make the residual stress into compression is cooled as quickly as possible. The side desired to make the residual stress into compression refers to the side where the improvement in performance such as stress corrosion cracking resistance is expected on account of turning of the residual stress into compression. When the surface is cooled after heating, stress of tension is first generated in the surface, but when the temp. in the central part of the plate thickness lowers after this and shrinkage begins to take place, the stress in the surface turns to compression side until finally the residual stress of compression is generated in the cooling side or the original residual tensile stress is relieved and the corrosion cracking resistance performance, fatigue resistance performance, etc. are improved.

Title: Core for rubber crawler
Inventor: SUMINO MAMORU
IPC: B62D55/253
Filed: 1995-05-07
Abstract: PURPOSE: To prevent peeling of rubber and cutting of the ends of a core embedded into a rubber elastic body constituting a rubber crawler by making the core thicker at its ends than at its inside, and chamfering each end into a C or R shape. CONSTITUTION: This core for use with a crawler rubber shoe in a rubber crawler uses its center portion 1 for connection with a link and has its right and left wings 3 embedded into a rubber elastic body. In this case, thick-wall portions 4, 4 are formed on the ground plane side of both ends of the core and are each chamfered into a C shape. A rib 7 is formed on the ground side of the center portion 1, and ribs 8 are formed on the inner peripheries of the wings 3. By thus forming the thick wall portions 4, 4 at both ends of the core, a contact area between the core and the rubber elastic body is increased to reduce a rate at which the rubber is peeled. Also, a rate at which the ends are cut off is reduced since no edges exist at the ends of the rubber elastic body and the core.
