Title: Digital copying machine
Inventor: OHASHI SHINICHIRO
IPC: H04N1/21
Filed: 1992-11-30
Abstract: PURPOSE:To prevent copy picture quality from deteriorating and to inhibit a confidential document from being copied by adding a frequency of copying from the original to a document and inhibiting a copy image from being formed when the frequency of copying is larger than a specific value. CONSTITUTION:A scanner part 1 photodetects original reflected light and detects image data on respective colors. Detected values of the original reflected light of the respective colors are processed by an image processing part 2 and converted into digital image data, which are stored in a memory 5. Image data showing the frequency of copying is extracted from the digital image data and the frequency of copying is discriminated. Then the discriminated frequency of copying is compared with the previously set inhibition frequency of copying and when the inhibition frequency is exceeded, a copy image is prevented from being formed. A numeric pattern generation part 4 generates the numeric pattern of the frequency of copying to be added to the copied image and the numeric pattern and the pattern of original image data are put together by a laser driving part 3 and outputted from a laser oscillator 18.

Inventor: HIRASAWA JUNICHIRO
IPC: B29C45/82
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To eliminate chattering by correctly controlling pressure of hydraulic oil. SOLUTION: In an injecting process, a pressure command setting apparatus 27 supplies operating currents different from each other to pressure control valves 25a and 25b by amplifiers 26a and 26b, and their pressures are set such that a set pressure of the pressure control valve 25b is smaller than a set pressure of the pressure control valve 25a by a predetermined value. A hydraulic oil is sent to a bottom of an injection cylinder 3 passing through branch pipes 5a and 5b of a main line 5 so as to move the injection cylinder 3 by injection. At this time, a pressure reducing valve 23b makes the hydraulic oil flow to the branch pipe 5b so as to heighten responsibility of pressure rise.  Also, a check valve 30 blocks back flow of the hydraulic oil which has passed through a flow rate control valve 13a to the branch pipe 5b, and leakage of the hydraulic oil from the pressure reducing valve 23b of small pressure setting is prevented.

Title: Clutter suppressor
Inventor: MURAKAMI KATSUHIKO
IPC: G01S7/292
Filed: 1988-12-20
Abstract: PURPOSE:To achieve a higher stability of a filter by arranging an arithmetic device to calculate a Doppler center frequency of a clutter and a memory having a coefficient of a lattice filter stored to address an output of the arithmetic device. CONSTITUTION:A clutter center frequency computing section 3 estimates a center frequency of a clutter from an input signal and a filter is so constructed adaptively to keep a shield center frequency at the frequency. Thus, it is pos sible to suppress a clutter depending on none of a Doppler frequency. As an operator determined a shield frequency band range according to a clutter envi ronment such as weather conditions, a filter always stable is formed. Moreover, a filter-oriented average gain stored previously is calculated to be stored into memories 4a, 4b and 4c together with a coefficient beforehand. Thus a gain controller 6 performs a gain adjustment using the average gain thus obtained thereby eliminating the need for a circuit for calculating the average gain.
