IPC: G06T1/00
Filed: 1987-04-10
Abstract: PURPOSE:To attain the retrieving processing with an indistinct keyword by preparing the feature of an image from the statistical information of an image and making it into the retrieving information of a registering image. CONSTITUTION:When a multi-value image is registered to an image storing part 3, a user inputs a keyword suitable as the retrieving information from an operation terminal part 5 and registers it. Further, the spectrum distribution of the multi-value image is calculated and registered with a spectrum distribution calculating part 7. The concentration distribution of the multi-value image is calculated and registered with a concentration distribution calculating part 8. Next, at the time of the retrieval of the image stored into the storing part 3, a keyword is inputted from the terminal part 5. When a user judges that the image, which is a purpose, is the image sharper than the image displayed presently, an instruction to retrieve 'brighter sharper image' is inputted from the terminal part 5. The instruction is inputted, the expected value of the spectrum distribution which is the retrieving information of the image which is a first candidate image, and the expected value of the concentration distribution are compared with the expected value of the image which is other candidate image and the image having a higher value is displayed.

Title: Automatic tracking device for communication signal wave
Inventor: HOTTA SHIGEAKI
IPC: G01S3/42
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To make the band width of a band-limiting filter narrow and to reduce transmission output for automatically tracking an opposite communication party by correcting a frequency shift by Doppler effect. SOLUTION: A voltage-controlled oscillator 8 receives a Dappler forecast value from a computer 9 and varies the local frequency corresponding to a Doppler shift quantity for continuously varying the received value. Consequently, a frequency converter 5 removes a Doppler shift component from a received communication signal to perform conversion to a stable intermediate frequency. Then its spectrum has its band limited by the band-limiting filter 6 to secure a high signal-to-noise ratio and then outputs an AGC voltage corresponding to the reception level to an antenna driving electronic circuit 11a. The computer 9 calculates the Doppler shift quantity at the same time with a relative position vector or a relative speed vector as required from the transmission frequency of the opposite communication party inputted from outside and position data on itself.  Then the forecast value of the Doppler shift quantity is outputted to the oscillator 8.

Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of troubles following sliding of a belt in a pulley unit having a one-way clutch by suppressing the sliding of the belt when the one-way clutch is switched to a locked state. SOLUTION: A power transmission retarding means 20 is arranged on one of outer and inner diameter sides of a one-way clutch 3, for retarding the power transmission between circular bodies 1 and 2 when the one-way clutch 3 is locked. The power transmission between a driving circular body and a driven circular body, that is, from the driving circular body (1 to 2) to the driven circular body (2 or 1) gradually performed when the one-way clutch 3 is locked. Instantaneous application of excessive rotational braking force to the driving circular body (1 or 2) is thus avoided. It is possible to suppress sliding of a belt 5 wrapped around the outer circular body 1.

Filed: 1978-07-25
Abstract: PURPOSE: To prevent occurrence of the foreign sound caused by the charge and discharge of the output coupling capacitor without changing the bias voltage of the current differential operational amplifier by turning on and off the output of the amplifier.  
     CONSTITUTION: The input signal sent from IN is put into input resistances 12, 14 and 17 after its DC component deleted. These input resistances form the input circuit of DC differential operational amplifier 21 and at the same time part of the power supply circuit of switching transistor 15. Transistor 15 is connected between input resistance 14 and 17, and the impedance of transistor 15 is smaller enough than resistance 17 when it is on. As a result, no input signal is transmitted to the input side of amplifier 21. When transistor 15 is off, the input signal is transmitted to the input side of 21 via resistance 17.

Abstract: PURPOSE:To suppress phenomena such as blooming and afterimages of a solid- state image pickup device by making a bottom of a well of a potential of a charge transfer part uniform for a vertical blanking period, averaging excess charges and removing them. CONSTITUTION:When excess light is made incident on a space between L-L' and voltages are impressed on transfer electrodes phiV1 and phiV3 for a period t1, excess charges 31 are read to a well of a potential under the electrode, and overflow, thereby filling an adjacent well. For a period t2 a voltage for making the bottom of the well of the potential under each transfer electrode uniform is impressed to the transfer electrode. These averaged excess charges are transferred and removed at a high speed for a period t3. A signal charge 32 remaining in a cumulative part is read to a vertical charge transfer part by impressing voltages to the transfer electrodes phiV1 and phiV3 for a period t4.
