Title: Control device of vacuum valve
Inventor: MURAYAMA YASUHIRO
IPC: E03F3/00
Filed: 1994-04-20
Abstract: PURPOSE:To prevent the malfunction of a control device in closing a valve element, and realize the smooth operation of the valve element by providing a communicating port whose diameter is smaller than the inner diameter of an atmosphere introducing port in a connection part of the atmosphere introducing port to a passage. CONSTITUTION:A communicating port 17a whose diameter is smaller than the inner diameter of an atmosphere introducing port 17 in a connection part of the atmosphere introducing port to a passage. The atmospheric air in the atmospheric passage system flows into a cylinder chamber of a vacuum valve from the atmosphere introducing port 17 through the passage 16. Because the diameter of the communication port 17a is smaller than the inner diameter of the atmosphere introducing port 17 at the connection part of the atmosphere introducing port 17 to the passage 16, the pressure difference is generated between the sides across the communicating port 17a, and the positive pressure generated in the atmosphere introducing port 17 is applied to the atmospheric chamber through a ventilation passage 20. The diaphragm is not malfunctioned to open a valve means, and the vacuum valve can be smoothly closed.

Inventor: OKAMOTO TAKASHI
IPC: B65G21/20
Filed: 1982-05-14
Abstract: PURPOSE:To contrive to unnecessitate a sorting operation, to prevent scattering and to automatize, by a method wherein a guide frame is momentarily formed between a chute and an opening of a bucket at the time of throwing in a mail, and a bucket conveyor is stopped when an excess throwing-in is detected. CONSTITUTION:When a sensor 8 confirms that the bucket 1a has reached a throwing-in positon of a mail, an air cylinder 9 is driven to lower a guide plate 6, thereby forming the guide frame at the opening of the bucket 1a by a guide plate 6, both side plates 4 and a skirt 5. Then, the belt conveyor 2 guidingly supply the mail for a predetermined period of time at predetermined timings, thereafter the cylinder 9 lifts up the guide plate 6, and the conveyor 1 is forwardly moved by a distance equal to the sum of the length of the bucket 1a and the spacing between the buckets 1a, resulting in a stand-by condition for receiving the next mail. An excess throwing-in is detected by a sensor 7, and the conveyor 1 is stopped. Accordingly, it can be contrived to unnecessitate a sorting operation, to prevent scattering and to automatize the throwing-in operation.

Abstract: PURPOSE:To easily attain an explaining function by adding the minitor functions to all or some neuron elements to monitor their own states and to output these monitoring results. CONSTITUTION:The monitor functions 5 are added to all or some neuron elements 4 to monitor their own states. The function 5 monitors the state of the due neuron elements and outputs this monitoring result. In such a neural net, the monitoring action of the function 5 is turned on as necessary and therefore the state of each element 4 can be known in the numerical value or in another expression. That is, the output of the element 4 of an intermediate layer 2 can be explained in a proper form against a question 'why ?' when the neural net produces a certain result. Thus an explaining function is easily added.

Title: Digital signal recording method
Inventor: YOSHIDA AKIYUKI
IPC: G11B5/02
Filed: 1986-04-09
Abstract: PURPOSE:To prevent such a defect where the recording depth of a low band signal is increased owing to the wear of a recording head and the over-write characteristics are deteriorated, by setting the magnetic gap width of the recording head at the value less than 1/2 the shortest wavelength of the digital signal to be recorded. CONSTITUTION:The digital signals are recorded on a magnetic tape containing a magnetic layer having at least double thickness or more compared with the shortest wavelength of the digital signal to be recorded. Under such conditions, the magnetic gap width of a recording magnetic head is set at the value less than 1/2 the shortest wavelength of said digital signal. As a result, the recording characteristics of the low band signal are deteriorated and therefore the increase of the recording depth owing to the increase of the recording current is suppressed for easy improvement of the over-write characteristics. Here about 1/4 gap width is actually best and the improvement of said over-write characteristics is reduced if the gap width is larger than said best value. While the recording characteristics are excessively deteriorated by a spacing loss, etc., if the gap width is smaller than the optimum value.

The sintered structure 10 as a molded structure is of a cylindrical shape with its internal peripheral part more protruded than its external peripheral part. Upon molding, on one filter side end surface 11 in contact with a filter uneven configuration of the filter is transferred, and hence burrs 17 are formed on the internal and external peripheries of the filter side end surface 11. The internal periphery of the filter side end surface 11 of the sintered structure 10 is polished to remove the internal periphery burrs. Thus, the internal periphery burrs are removed with excellent mass-productivity in an automated line.

Filed: 1993-04-08
Abstract: PURPOSE:To circulate water to prevent its freezing state by a method wherein a circulation pump is instantly rotated when a heating operation is erroneously stopped during a heating operation caused by a freezing preventing operation. CONSTITUTION:In case that a heating operation is erroneously stopped due to some troubles occurring in a hot water feeding temperature sensor or a heater 4, a circulation pump 2 and the heater 4 are stopped, resulting in that hot water is neither circulated nor heated and so the water is freezed. In this case, an error sensing means 8 detects that the heating operation is erroneously stopped and thereby a heating operation control means 7 rotates instantly the circulation pump 2 if a heating operation signal got from an anti-freezing operation control means 6 is ON. With such an arrangement, water is circulated to prevent its freezing.
