Title: Telephone equipment for conference
Inventor: HASEGAWA HIROSHI
IPC: H04M3/56
Filed: 1993-04-28
Abstract: PURPOSE:To reduce cost by canceling sidetone caused by plural voice signals by using one echo canceler. CONSTITUTION:The voice signal of a microphone 48 at a telephone set 21 is supplied from an adder 54 and two-wire/four-wire conversion circuits 22-1-22-n to respective telephone sets. The voice signal of any one telephone set is supplied from the conversion circuit 22-1, for example, adder 34 and echo canceler 36 to the telephone set 21. The output signal of the canceler 36 (the signal of the conversion circuit 22-1) is also supplied from an adder 54 to the conversion circuits 22-1-22-n and sent to each telephone set. At such a time, the sum of the voice signal of the telephone set 21 and the voice signal of the conversion circuit 22-1 is supplied from the conversion circuits 22-1-22-n to the adder 34 as the sidetone and supplied to the canceler 36. Since the output signal of the adder 54 (the voice signal of the telephone set 21 and the voice signal of the conversion circuit 22-1) is supplied to the canceler 36 as a control signal, this sidetone is canceled.

Title: Method for counting stacked platelike substances
Inventor: NISHIO MASANORI
IPC: G06M9/00
Filed: 1989-05-19
Abstract: PURPOSE:To accurately count up the number of stacked platelike substances by comparing the brightness level of the stacked platelike substances with a prescribed threshold and counting the number of repeats of comparing data to find out the number of stacked platelike substances. CONSTITUTION:The brightness level of an image for the end face of an object 1 to be counted is scanned in the stacked direction through a CCD linear image sensor 4 and an obtained output signal 4a is inputted to an A/D converter 7 through an amplifier 6 to obtain digital output data 7a. The data 7a are written in an image data memory 9 from a memory writing circuit 8 to obtain a value corresponding to a change in the cross section of the object 1. The data of the memory 9 are computed by an arithmetic circuit 10, and if a periodical change is extracted, the object 1 can be counted. As to the operation, a threshold e.g. is prepared to compare the size of the data 7a with the threshold. When threshold <=data 7a is set up to '1' and threshold>data 7a is set up as '0', the number of stacked plates of the object 1 can be decided by counting up the number of changes from '0' to '1'.

Title: Automatic paper feeder
Inventor: IGUCHI MICHIHISA
IPC: B65H9/00
Filed: 1981-08-11
Abstract: PURPOSE:To enable even original copies of different sizes to be securely fed together, by exerting a pressure on a paper surface at a position spaced from a reference guide surface located farther than a position where a feeding force is exerted, in an automatic paper feeder for a copying machine or the like. CONSTITUTION:An original copy on a paper feed table is pressed by the weight W of a weight roller 14. When the original copy 1a is fed by a feed roller 3 and a reversely rotatable roller 4, a frictional load f2 corresponding to the coefficient of friction of the surface of the original copy at the part pressed by the roller 14 is exerted on the original copy 1a in the direction opposite to the feed direction. On the other hand, a feeding force f1 of the roller 3 is also exerted on the original copy 1a. Therefore, the original copy 1a is applied with a couple of forces in the direction of an arrow D due to the feeding force f1 and the frictional load f2, the copy 1a is pressed against a guide surface 12a of a guide vane 12 and is guided along the guide surface 12a. Accordingly, even original copies having different widths are guided straightly without any tilting and are fed accurately.

Filed: 1980-09-10
Abstract: PURPOSE: To improve the gasification function and facilitate the replacement of the combustion device by arranging an aluminum bubbling body on the surface of the gasifying part which gasifies the liquid fuel of a burner main body.  
     CONSTITUTION: A cup-shaped aluminum foaming body 1a is arranged on the surface of the gasifying port 1' which gasifies the liquid fuel of the burner main body 1 screwed to a screw part threading a cap 2 and a mixing partition plate 3. By this procedure, the foaming body 1a is imparted an irregular three-dimensional mesh structure and a large surface of contacting with kerosene, and also a large affinity with kerosene. The gasifying ability of the foaming body 1a becomes large without producing liquid bubbles and the like. Since gasifying surface consists of an Al foaming body and the heat capacity thereof itself is small and further has an excellent heat transmission, the temperature increase is rapidly performed and adhered fuel can be rapidly gasified and generation of tar is reduced.

Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To obtain a vacuum processing system applicable to vacuum process over a wide pressure range by disposing a displacement regulation valve, along with a pressure regulation valve, on an exhaust pipe coupled with a vacuum chamber and to shorten the total processing time by shortening both the rising time and the exhausting time. SOLUTION: Under a state where the gas on/off valve 21 of a gas supply pipe 12 is closed, an exhaust on/off valve 13 of an exhaust pipe 22 before fully opening a pressure regulation valve 14 and a displacement regulation valve 16. Under maximum flow rate state, an exhaust pump 18 is driven to evacuate a vacuum chamber 11 and discharge the residual gas thus bringing about a specified high vacuum state corresponding to the capacity of exhaust pump. Subsequently, the pressure regulation valve 14 is fully opened and a displacement regulation valve 17 is set at a preset opening before the gas on/off valve 21 is opened to introduce a reaction gas into the vacuum chamber 11. Consequently, the inner pressure of vacuum chamber 11 increases.  Since the displacement is restricted by the displacement regulation valve 17 under that state, the rising time is shortened even if a pump having large displacement is used.

Abstract: PURPOSE: To facilitate processing of the original on the occasion of jamming, by controlling the feed and discharge of the original in different modes at the time of interruption of copying and completion thereof.  
     CONSTITUTION: A control computer Q 1  provides realtime displays of input judgment of imput keys, setting of the number of copies, cassette size, initial state of copying machine, etc., and applies an enable signal to an AF computer Q 3  which generates a copy end signal to set the original discharging belt in the active state. On the other hand, the copying machine is sequence-controlled through a sequence control computer Q 2 , and the original is discharged by the end signal generated by the computer Q 3  when copying is over or when the set number of copies and the number of copies being taken are cleared. When copying is interrupted due to detection of jam by the computer Q 2  in the midst of copying within the set number of copies, enable signal is not applied from the computer Q 1  to the computer Q 3 , so that the computer Q 3  will not produce an end signal.

Abstract: PROBLEM TO BE SOLVED: To enable easily regenerating a vaporizer and restoring it to working order relating to regeneration of one set in a combustion apparatus for burning fuel by vaporization and having degenerated in the ability because of attachment of tar. SOLUTION: The length (a) of the vaporizing element insertion part of a vaporizing chamber holder 31 is made roughly more than one half the length (b) of the vaporizing element 32. Therefore, even when the vaporizing element 32 has become tarred so heavily that this element and the inner surface of a vaporizing chamber 30 of the vaporizer body 25 stick fast, the removal of the vaporizing chamber holder 31 leaves the vaporizing element 32 and the vaporizing chamber holder 31 attached together. Therefore, the vaporizing element 32 is easy to replace and the vaporizer is easy to regenerate.
