Title: Radar device
Inventor: MATSUGAYA KAZUOKI
IPC: G01S13/93
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To secure improved detection sensitivity in a total range up to the requested maximum detection range in a radar device for detecting the distance to a target object and the relative velocity using a radar wave where frequency is doubly modulated by a DC modulation component and a periodical modulation component. SOLUTION: When a requested maximum detection distance is set to Rmax, the space wavelength of a radar wave with a frequency Fs of a periodical modulation component is set to λs (=c/Fs: c indicates light speed) and the frequency Fs of the periodical modulation component is set so that λs/2 > Rmax can be satisfied. A beat signal being obtained by transmitting and receiving a radar wave being modulated by the periodical modulation component and mixing the transmitted and received signal decreases its signal intensity when distance to a target object is equal to an integer multiple of λs/2 but does not decrease its signal intensity (and hence detection sensitivity) within a range up to the maximum detection distance Rmax due to λs/2 > Rmax.

Title: Digital filter
Inventor: TANAKA HIROSHI
IPC: G01N30/86
Filed: 1990-09-29
Abstract: PURPOSE:To make a register forcibly stable when an input sudden change takes place by providing an arithmetic means for calculating a final value from an input or an output to the filter and using an output of the arithmetic means so as to forcibly update the register on the occurrence of a sudden change in an input value or a filter time constant. CONSTITUTION:An IIR digital low pass filter is provided with a multiplier 7 multiplying an input Vi with 1/alpha and either an output of an adder 4 or an output of the multiplier 7 is fed to a register 1 by the selection of a switch 9. A contact S1 of the switch 9 is closed on communication to connect the output of the adder 4 to the register so as to allow the circuit to act like a low pass filter. However, when, e.g. an input changes suddenly, a contact S2 is closed, the output of the multiplier 7 connects to the register 1 resulting that the content of the register 1 is forcibly updated to a final stable value V1X1/alpha corresponding to the case that the register 1 is not connected to the multiplier 7. Thus, the filter output is made stable in a short time.

IPC: B09B5/00
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To prevent the collision of charged bottles against projections on the surface of steel aprons and the consequent breakage thereof or the collision of the bottles falling along a slope against a transporting conveyor for transporting the bottles to a place for executing the next stage and the consequent breakage thereof, the resultant difficulty in their recovery and the extremely difficulty in their sorting by forming these projections of buffer materials. SOLUTION: Since the projections 25 are formed of the buffer materials, the breakage of the bottle-like waste 2 may be prevented even if the bottle-like waste 2 dropped from a pit for waste collide against the projections 25. The sheet-like waste 3 falling from the charging section for waste are caught by the projections 25 moving along plural slits 24 disposed in a transverse direction and are discharge from a discharge section 23 by moving in the transverse direction of a receiving sheet 20 and, therefore, the distance at which sheet-like waste 3 is transported for the purpose of discharge is short. The efficient sepn. of the bottle-like waste 2 and the sheet-like waste 3 is thus made possible.

IPC: H04N3/185
Filed: 1984-12-12
Abstract: PURPOSE:To obtain an optional horizontal pattern amplitude by making the horizontal pattern amplitude and a high voltage constant always regardless of changes in a horizontal deflection frequency so long as a blanking time TR is constant and changing a blanking line resonanceimpedance at the primary winding of a flyback transformer to change the TR. CONSTITUTION:As a resonance frequency variable means, a series circuit comprising an amplitude adjusting changeover switch 24 and an auxiliary resonance capacitor 25 is connected to parallel with a capacitor 5 at the primary side of the flyback transformer 6. In turning on the switch 24, since the capacitance of the capacitor 5 is added to that of the capacitor 25 and the combined capacitance C is larger, the blanking time TR gets longer. Since the deflection current I is increased, the horizontal pattern amplitude is expanded.

Title: Image pickup device
Inventor: SUZUKI KENJI
IPC: G03B27/72
Filed: 1988-10-20
Abstract: PURPOSE:To prevent distortion from being generated in an image-pickup picture and to prevent the ununiformity of illuminance from being generated by forming the photosensitive part of an image sensor to be similar to the projection shape of a picture and obtaining an area corresponding to the projection shape of the picture for respective pixels. CONSTITUTION:An image pickup lens 24 and an image sensor 25 are arranged in a position, which is deviated from a printing optical path 15, so that no trouble can be caused on a photographic print. This image sensor 25 is arranged in a condition to be inclined to a negative film 16 only by an angle theta. In such a case, a photosensitive part 25a of the image sensor 25 is formed so as to correspond to the projection shape of the picture. Thus, the distortion of an image due to the oblique image-pickup of the picture can be canceled. Since the area of a pixel PE is changed corresponding to the distortion of the image, the ununiformity of the illuminance can be eliminated in the photosensitive part 25a.
