Title: Production of alloy powder for rare earth-boron-iron permanent magnet
Inventor: KIMURA ETSUJI
IPC: B22F9/04
Filed: 1987-06-10
Abstract: PURPOSE:To decrease the contents of Ca and O in Nd-B-Fe powder in particular by adding a specific ratio of a complexing agent to a cleaning liquid in a process for production consisting in subjecting the resulted product of reaction obtd. by mixing and reduction diffusing of raw material powders to grinding, rinsing, dehydrating, and vacuum drying. CONSTITUTION:The resulted product of reaction obtd. by mixing and reduction diffusing of the raw material powders is ground and is then cleaned. The cleaning is executed by using the cleaning liquid added with 10<-5>-1mol/l complexing agent. Or the product is cleaned by the cleaning liquid added with 10<-3>-10<-2>g/l inhibitor (corrosion inhibitor). The complexing agent has an effect of removing the hydroxide generated by rising the resulted product of reaction. The effect of decreasing Ca and O is substantially nil if the amt. of the complexing agent to be added is below 10<-5>g/l. Said decreasing effect is not improved even if the amt. exceeds 1mol/l. Even more, the impurities, such as C, S and N, which are unfavorable for magnetic characteristics increase in such a case.

Abstract: PURPOSE:Not only to display the necessary items of an article but also to form and seal a bag part just by sticking by providing a 1st cut line formed from one end to the other end of a released paper and a 2nd cut line formed so that it may be connected to two spots of the 1st cut line. CONSTITUTION:The released paper 16 can be peeled off as a whole or at the parts of the 1st cut line 18 and the 2nd cut line 20. By peeling off the paper 16, a sticking adhesive layer 14 is exposed and a base material 12 is stuck, for instance, on the surface of the article with the aid of the layer 14. As to the paper 16, by peeling off the part outside the 2nd cut line 20, exposing the sticking adhesive layer 14 and sticking the base material 12, for instance, on the surface of the article with the aid of the layer 14, the bag part can be formed between the base material 12 and the surface of the article. Furthermore, the part outside the 1st cut line 18 of the paper 16 can be peeled off. Thus, the bag part is sealed by sticking a part of the base material 12 on the surface of the article with the aid of the exposed layer 14.

IPC: F23D11/44
Filed: 1995-06-12
Abstract: PURPOSE: To ensure stable combustion, restrict production of tar to a vaporization chamber bottom part, and restrict production of bad smell upon starting and interruption of combustion by forming a vaporization chamber on the outer periphery of an inner cylinder, and providing a plurality of vents in a peripheral wall upper part of the inner cylinder, the vent communicating the upper part of the vaporization chamber and the interior of the inner cylinder. CONSTITUTION: Liquid fuel ejected from a combustion nozzle 11a partly makes contact with a vaporization surface facing the fuel nozzle 11a and is instantaneously vaporized. Fuel not enough vaporized is widely expanded with a combustion air stream flowing along between the inner cylinder 2a and a peripheral wall 2 of a vaporizer 1a for promotion of vaporization. Vaporized gas of the liquid fuel vaporized owing to the contact with the vaporization surface is mxed with combustion air in the vaporization chamber 10 along a long path formed on the outer periphery of the inner cylinder 2a into a mixture gas. The mixture gas enters the inner cylinder 2a from a vent hole 2b in the upper part of the peripheral wall 2c of the inner cylinder 2a and is supplied into a burner head 13 after passage through a throttle opening 12a in a throttle plate 12 so that mixing is promoted.

Title: Multi-item input device
Inventor: MAEDA NOBUYOSHI
IPC: G06F3/023
Filed: 1979-11-08
Abstract: PURPOSE: To ensure a high-speed input process, by cutting the page selecting control which is carried out by a page control circuit.  
     CONSTITUTION: With push of the page selection key 1, the key input signal is stored in the buffer memory circuit 5 via the encoder 5. Thus the page control circuit 8 which received the designation from the designation switch circuit 7 cuts the working control of the page selection mechanism 10 and gives a command immediately to the timing control circuit 6 to make the operation of the item input key 3 possible. As a result, no conventional operation is required after the item of the key 3 is displayed, and accordingly the expert operator who memorizes the item display by himself can have a high-speed input process. And the operating method identical to conventional one is possible as long as no designation signal is delivered from the designation switch circuit 7.

Title: Fm receiver
Inventor: ISHII HIDEKAZU
IPC: H04B1/10
Filed: 1980-10-16
Abstract: PURPOSE:To improve the tracking performance to the reception level change of muting operation, by detecting a minimum value of reception signal level and giving muting to the FM detection output when this minimum value is smaller than the specified value. CONSTITUTION:The output of a signal level detector 11 detecting a signal level of an intermediate frequency signal is inputted to a minute voltage detector 31. This detector 31 detects the lowest voltage from a variable voltage applied to the input and stores the result for a set time. If the output of the detector 11 falls down through the variance by the interference on electromagnetic wave propagation, the output of the detector 31 follows it for reduction, and muting can be given to a switch circuit 19 via an AND circuit 13, allowing to avoid unpleasant noise from an FM receiver. The time constant is selected so that the output of the detector 31 is stored for the set time and since the muting is released so that output can be made gradually without rapid release of muting, audible unpleasantness is made less.

Title: Vacuum cleaner and its suction aperture assembly
Inventor: TAJIMA TAIJI
IPC: A47L9/04
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To provide the suction aperture assembly of a vacuum cleaner which is of a small-size and light-weight type and is less noisy as well as a vacuum cleaner using this suction aperture assembly. SOLUTION: The suction aperture assembly is internally equipped with an impeller 103 which rotates by a suction force, and a rotary brush which has a brush or a blade 104 coming into contact with a face to be cleaned, implanted helically in the entirety or part of the impeller and coaxially rotates with the impeller in one piece, without an interstructure or the like formed between the impeller and the rotary brush. Thus it is possible to constitute a rotary brush and/or a rotary blade on the same axial line as the impeller and therefore, make the suction aperture assembly small-sized and light-weight.  In addition, an air is sucked almost entirely from an opening opposite to the face to be cleaned by uplifting the suction aperture assembly, so that the rotation of the impeller is slowed down or stopped and consequently, a noise to be generated by the light-speed rotation of the rotary brush and/or the rotary blade when the suction aperture assembly is uplifted is prevented from being generated.
