Title: Document presenting device
Inventor: ICHIHARA KENJI
IPC: H04N5/222
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To make speed in appearance constant even when a zoom of a camera part is at a wide-angle state or a telephotographic state by increasing speed of pan/tilt operation when the camera part is at the wide-angle state and decreasing the speed of the pan/tilt operation when the camera part is at the telephotographic state. SOLUTION: Operation speed of the camera part 11 is increased when a zoom is at the wide-angle state and is decreased at the telephotographic state in the pan/tilt operation of the camera part 11. Increasing and decreasing of the speed is performed by variably controlling voltage to be applied to a DC motor 26 for tilt as a driving source of a tilt mechanism part 12 and a DC motor for pan as a driving source of a pan mechanism part 13. In this case, the voltage to be applied to the DC motor 26 for tilt and the DC motor for pan to perform the pan/tilt operation according to zoom magnification of the camera 11 is stepwise varied. Thus, video to be projected is viewed at the constant transfer speed in appearance in the pan/tilt operation.

Title: Grinding tool
Inventor: WAKIHIRA KOICHIRO
IPC: B23F21/00
Filed: 1985-09-25
Abstract: PURPOSE:To prolong the life of a tool by putting the tooth surface of a gear to be machined in surface contact with a curvature consisting of the involute curve on a tooth body of tool and the curve on the crest of tooth, when meshed grinding is carried out, and thereby eliminating overload on the curvature. CONSTITUTION:A gear cutting tool 1 carries out machining while each of its teeth 1a meshed with teeth 4a of a gear to be machined 4. That is, the meshing point of a tooth 1a of the tool 1 with a tooth 4a of the gear 4 varies from time to time, thereby the tooth surface 4c of the gear 4 is ground into involute form with a number of abrasive grains at the tooth body 1e of the tool tooth 1a. Here eventual contact of the tooth crest 1c of the tool and the curvature 1b as boundary between it and the body 1e with the tooth surface 4c of the gear 4 will be made in surface contact, so that the load applied to the curvature 1b will be less to prevent the curvature part from separation of abrasive grains 3 as well as defoliation of the plating layer 2. A bent form at the crest and each corner of tooth ensures that eventual projection of the crest in the radial direction does not cause contact with the gear, which will provide uniform sense of sharp cutting with abrasive grains.

Title: Dropout measuring apparatus
Inventor: YASUMURA KIYOSHI
IPC: G11B5/84
Filed: 1983-11-15
Abstract: PURPOSE:To facilitate the detection of a dropout by measuring the attenuation of a missed signal obtained from the AM detection of a reproduction signal of a magnetographic medium and the missing time thereof. CONSTITUTION:A reproduction signal 11 is detected with an AM detector 12 and compared with a preset threshold level 14 set for a comparator 13. Now when the level of the signal 11 exceeds the level 14, a counter 18 is started to count a dropout and the range of the dropout (missing time) is latched into an output latch 20. While the detection signal renews the peak of the attenuation, the maximum value thereof is memorized into a peak detector/holder 15. Subsequently, the detection signal is digitized with an A/D converter 16 and the depth (attenuation) of the dropout is latched with an output latch 17. This operation is repeated sequentially at each frame and the missing time and attenuation in the dropout is shown on a display 21.

IPC: H02P6/14
Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To provide the control device of a brushless motor for enabling advance angle control for allowing the switching time of the conduction state of a switching element to precede the change time of a rotor magnetic pole which is detected by a magnetic sensor, regardless of software. SOLUTION: If a capacitor C2 is charged, when the magnetic pole of a sensor magnet 5 detected by magnetic sensors IC1-IC3 changes, and the voltage reaches a rotational speed signal FV1 corresponding to the change frequency of the magnetic pole, a second timer circuit 50 inverts an advance angle time setting signal MS to a high-voltage level. A latch circuit 110 generates advance angle post-signal S1B-S3B, that are made to precede advance angle with respect to pre-signals S1-S3 by advance angle time, based on the advance angle time setting signal MS. When the rotational speed signal FV1 exceeds an advance angle start rotational speed setting FV/MG, a selection circuit 120 selects the advance angle post signal, and a switching circuit 20 is driven by a gate signal which is generated from the advance angle post-signal.

Title: Risk minimized portfolio selection device using mutually coupled network
Inventor: IZUMI HIROYUKI
IPC: G06F19/00
Filed: 1989-08-19
Abstract: PURPOSE:To obtain an optimum fund distribution ratio to each brand so as to minimize the total risk with a fixed total return by using a problem that minimizes the energy function of a mutually coupled network. CONSTITUTION:The fund distribution ratios are set opposite to each other among plural brands in terms of the value 14 of each node of a mutually coupled network. A link weight setting means 6 sets each link weight value 13 so that the total risk is automatically minimized and at the same time the total return is most approximate to the input total return 9 when the energy function value of the network is minimized. Under such conditions, a node value updating means 7 calculates an optimum fund distribution ratio 15 as each value 14 when the energy function is minimum. Thus it is possible to obtain the ratio 15 to each brand so as to minimize the total risk with a fixed return.

Filed: 1986-09-10
Abstract: PURPOSE:To attain both the miniaturization of a facsimile equipment and highly efficient compression of picture information by calculating auto-correlation and cross correlation as each line of picture information and selecting the coding method of information taking the coefficients into account. CONSTITUTION:A selection section 20 is provided to calculate its auto-correlation coefficient and the cross correlation coefficient are calculated as each prescribed unit of picture information and the coding method is selected and designated based on the result. That is, the autocorrelation coefficient by horizontaly adjacent picture elements as each line and the cross correlation coefficient by vertical adjacent picture elements are obtained. Since the autocorrelation coefficient represents the horizontal correlation and the cross correlation coefficient depicts the vertical correlation, which degree of correlation in the horizontal and vertical directions the line of picture information has is judged based on both the coefficients. The coding method is decided in a way that linear coding (MH coding) is applied if the horizontal correlation is strong and 2-dimension coding (MR coding) is applied if the vertical correlation is strong and no coding is applied and picture information is sent without any modification if both the correlations are weak.

IPC: B65H1/26
Filed: 1994-09-08
Abstract: PURPOSE: To inform an operator about inferior insertion of a paper feed cassette in such a way that the cassette is pulled to a predetermined position so as to completely mount the cassette if the cassette is inserted across a critical point, but the cassette is discharged if the cassette is not inserted up to the critical point. CONSTITUTION: When the fitting between a stopper 4 and a guide member 3 comes to a critical point 6, the stopper 4 is pulled in a cassette insertion direction by a spring member 5 even though the operator releases a force for inserting the cassette 1, and accordingly, the cassette is led to and secured at a predetermined position in a cassette storage part. Thus, paper feed is surely made. If the operator releases the cassette insertion force before the cassette 1 reaches the critical point 6, the stopper 4 turns downward from a position above an inclined side of a guide member 3, and accordingly, the cassette is discharged. With this arrangement, it is possible to inform the operator about inferior insertion of the cassette.
