Title: Bucket of rhizome root digger
Inventor: KOBASHI TERUHISA
IPC: A01D31/00
Filed: 1984-04-20
Abstract: PURPOSE:To prevent damage to rhizome (or lotus root) by a method in which the side face of curved digging claws constituting a bucket is made thinner in shape gradually toward the tip side and the plane shape is also made narrower gradually toward the basal end. CONSTITUTION:Plural fitting boxes 28 are provided at a given interval in the widthwise direction on the tip side of the base 27 attached to an arm 13 through a pin 16. Digging claws 29 are detachably attached to the fitting boxes 28 to make up a bucket 15. The side face of the claw 29 is made thinner in shape gradually toward the tip side but made thicker toward the basal end, and the plane shape is widened toward the tip but made narrower gradually toward the basal end. Since the driving and cutting-in resistance of the bucket 15 is smaller, rhizome (or lotus root) can be taken out by digging without causing damage to rhizome root and its buds and soil adhered to the rhizome can be removed out.

Title: Image processor
Inventor: MATAMA TORU
IPC: G06K15/12
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To secure a sufficient dynamic range of image data even when a high-contrast scene is photographed by a digital camera, etc., with narrow latitude by synthesizing image data of plural images, obtained by photographing the same scene under different exposure conditions, together into one image and performing a dodging process for the synthesizing image data. SOLUTION: A synthetic image selection part 46 of an image synthesizing part 42 detect pieces of image data of the same scene which differ in exposure condition among supplied data by using at least one of photography information and image data and a part which selects optimum image data for synthesis uses both the photography information and image data to select two optimum image data for synthesis. As the photography information for selecting the image data to be synthesized, for example, image data which are close in photography time are selected. Then the dodging process is performed preferably for the image data obtained by synthesizing image data of the same scene having different exposure conditions.

Title: Fsk modulator
Inventor: FUKUCHI AKIO
IPC: H04L27/12
Filed: 1992-04-03
Abstract: PURPOSE:To accurately modulate high-speed data which are used for a digital data communication. CONSTITUTION:A variable frequency divider 2 divides the frequency fout outputted from a VCO 1 by N and a phase comparator 3 detects the phase difference between the frequency-divided signal and an OSC 5. The detected phase difference is converted by an LPF 4 into a DC voltage, which is fed back to the VCO 1. This is repeated to lock a loop and the stable fout is obtained. This fout can be varied by varying data inputted to the variable frequency divider 2 through a logic gate 6. The variation of the data is synchronized by a D flip-flop circuit 7 with the variable frequency divider 2 to enable the accurate high-speed data transmission from which malfunction is excluded.
