Abstract: PURPOSE:To know the location of a cordless telephone set without fail by registering necessary items in advance before using the cordless telephone set, communicating the locating place of a present set from the cordless telephone set with a code signal, etc., suitably and displaying the signal on a display. CONSTITUTION:In a golf field, for example, a hole number 01 is inputted from an input part 8 and stored in a memory area 22 before the play. Next, the number is stored as the 'first hole' in a hole number memory area 23 by a speech recognition part 13. Similarly, a specified spot is registered. When this registration of data is finished, a cordless telephone set 5 calls a control part 6 by dialing. For example, when the play is executed from now at the third hole, at first, the name of a party and a start place, etc., are successively inputted. The signal passes through the control part, is processed at a dial signal identification part 7 and displayed at a display part 15.

Title: Manufacture of high-density ferrite
Inventor: FUKUSHIMA GEN
IPC: H01F1/36
Filed: 1986-12-22
Abstract: PURPOSE:To manufacture fine-particle high-density ferrite by sintering the ferrite material under the temperature resulting in density of 90% or more and average particle size of 15 mum or less and pressing the sinter with hot static waster pressure at a temperature lower than the sintering temperature and enough to allow no particle growth. CONSTITUTION:A first sintering is carried out at the specified sintering temperature T1 (1050 deg.C<=T1<=1250 deg.C), and particle growth of crystal particle is suppressed at 15 mum or less; thereby, a sinter of ferrite with density of 90% or more can be obtained. Next, density of sinter of ferrite is set to 99% or more and average particle size is set to 15 mum or less through the pressing with hot static water pressure at the temperature T2 (where, 1000 deg.C<=T2<=1200 deg.C, T2<=T1-50 deg.C) which is lower than the temperature T1 and does not substantially allow the particle growth. Thereby, fine-particle high-density ferrite can be manufactured.

Title: High-frequency acceleration device
Inventor: KANEKO HIROSHI
IPC: H05H7/02
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To improve acceleration efficiency remarkably by eliminating the influence of a phase variation in a short period region to which phase feedback control can not perfectly respond. SOLUTION: A cathode voltage detector 24 outputs a detection signal of the cathode voltage of a Klystron 9 to a correction signal output circuit 25. At that time, a phase difference detector 19 outputs a signal showing a steep phase variation to which feedback control in a short period region can not perfectly respond. The correction signal output circuit 25 outputs a correction signal to cancel the steep phase variation based on the signal from the cathode voltage detector 24. An adder 26 outputs, to a control-purpose phase shifter 14, a signal formed by adding the correction signal to a signal from a phase control circuit 20.

Filed: 1993-12-06
Abstract: PURPOSE:To observe a display object more stereoscopically and to easily and quickly grasp a characteristic of a concerned area by repetitively displaying a 3-dimension picture in the vicinity of a visual point pointed out by the operator. CONSTITUTION:An instructed visual point 33 is obtained at a visual point entry means 32 according to an instruction of the operator. Then a visual point string decision means 34 obtains a vicinity visual point string 35 based on an instructed visual point 33 obtained by the visual point entry means 32. The vicinity visual point string is generated by preparing a table storing changes in a rotation angle and an elevating angle (or inclination angle), e.g. in advance and adding each element in the table to the instructed visual point 33. Finally, a display control means 36 generates a 3-dimension picture when viewed from each visual point on the vicinity visual point string obtained by the visual point string decision means 34 and displayed repetitively to a picture display area. When the operator changes the instructed visual point 33, a mouse cursor of the visual point entry area is moved to other position and a mouse button is clicked.

IPC: H04N19/48
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To remarkably improve a picture and to unnecessitate a picture memory of a large capacity by generating DC component correction data for correcting an objective inverse transformation DC component corresponding to an objective block picture through the use of the inverse transformation DC component to effectively reduce block distortion. SOLUTION: This decoder is provided with a correction processing part 10 averaging inverse transformation DC data corresponding to each block and generating DC component correction data Yn of the objective block. This correction processing part 10 stores inverse transformation DC data being the DC component of the adjacent block 7 of the objective block in a DC component memory 11 to use an averaged value with the DC component of a decoding objective block as DC component correction data Yn. Consequently, the difference mutually between the DC components of the adjacent blocks 7 is made very small without necessitating the picture memory of a large capacity for holding a composite picture, to reduce the noise factor of an output picture such as block distortion.  By changing the value of a DC component control signal, the change of an averaging rate can be possible, to realize the removing of noise corresponding to the picture.
