Title: Device for monitoring screw compressor
Inventor: HIBINO YOUZOU
IPC: F04C28/28
Filed: 1980-04-09
Abstract: PURPOSE: To accurately seize the running condition of a screw compressor, by providing a monitoring device comprising a storage section, a counting section and a calculating section.   
     CONSTITUTION: When a suction restricting valve 4 is open and a wind release valve 5 is closed  and discharge pressure reaches an upper limit level, a regulator 8 supplies an output signal for  closing the suction restricting valve 4 and an output signal for opening the wind release valve 5 to  lower the discharge pressure. When the discharge pressure reaches a lower limit level, the regulator 8 supplies an output signal for opening the valve 4 and an output signal for closing the valve  5. A counting section 11 receives valve opening and closing signals from the regulator 8 and  measures the opening and closing periods of the valves 4, 5. The counting section 11 also receives  a discharge pressure signal from a discharge pressure detector 6 and determines the ratio of air  quantity, namely, the rate of flow on the basis of the values of the signals. The ratio of motive  power and the relations between the ratio and the opening and closing periods of the valves 4, 5  are stored in a storage section. A calculating section 13 determines present motive power from the  present opening and closing periods and the relations stored in the section 12. The determined  flow rate and motive power are transmitted to an appropriate output unit 14.

Title: Track simulator
Inventor: KATSUYAMA SHIZUKA
IPC: G01S7/40
Filed: 1989-02-27
Abstract: PURPOSE:To carry out correct simulation by a method wherein when generation timing of a trigger reset signal is in output timing of a simulation track signal, a simulated track signal is canceled by a cancel signal having wide pulse width after generation of a trigger set signal. CONSTITUTION:When generating timing of a trigger reset signal is in output timing of a simulated track signal (a), a simulated track signal canceling unit 2 generates a trigger reset signal to output a cancel signal having a wider pulse width than that of the simulated track signal (a) after trigger reset signal generation, and the simulated track signal after the trigger reset signal generation is canceled by this cancel signal so that a simulated track signal (b) being only a front half of the simulated track signal (a) is output. This enables a bright spot to be displayed only at an outermost position of a plane position indicator (PPI) scope 4 thereby giving correct simulation training to a radar supervisor.

Title: Detecting method for focusing point
Inventor: SASAKI SHUJI
IPC: G02B7/28
Filed: 1986-03-05
Abstract: PURPOSE:To shorten a processing time by fixing a binarization threshold at the detection of a focusing point and finding out a position where the area of a image entered by moving a camera is maximized. CONSTITUTION:When there is a difference between the size of an object in a visual field and that of its background, the binarization threshold is fixed on a value capable of clearly distinguishing the object from the background, an image is entered by moving the camera so that the object or the background having a smaller area is left on the image and the position where the area of the entered image is maximized is defined as the focused point position. For instance, a picture element whose lightness level is close to LEV becomes a picture element wish an intermediate level between the dark level of the object and the bright level of the background, i.e. a picture element on the outline part of the object. Namely, an image with high contrast has a sharp change in the lightness level of the outline part and the number of picture elements having the lightness level in the range are reduced. Consequently, the object can be entered as the most approximated state to the actual object by setting up the threshold to a trough between two ridges, i.e. near the LEV, and binary coding to fetch the object in the state most resembiling to the real matter so that the processing can be simplified.

Abstract: PURPOSE:To shorten the transmission time and compress the transmission band by defining respective scanning lines of an original as even and odd picture element coding lines alternately. CONSTITUTION:Respective scanning lines of the original are defined as even and odd picture element coding lines alternately. A run length signal corresponding to even-numbered picture elements of the binary picture signal from original read means 1 in the even picture element coding line and a run length signal corresponding to odd-numbered picture elements of the binary picture signal above in the odd picture element coding line are compressed and coded by coding memory 6 and are transmitted to the receiving side.

Title: Package for semiconductor integrated circuit
Inventor: NAKAMURA HIROTAKA
IPC: H01L23/50
Filed: 1991-03-12
Abstract: PURPOSE:To enable a lead inductance of a power supply and a grounding terminal to be reduced and fluctuation of a grounding potential to be suppressed for preventing malfunction by providing a capacitor within a package structure. CONSTITUTION:When current flows to an outside of an LSI from a chip 1 through a wire 2, a thorough-hole 14, a grounding potential metal layer 11, and a metal lead 15, a current change rate is sharp and at the same time current flows also to an equivalent capacitor 17. An impedance of the grounding potential terminal is expressed by a parallel connection of inductance components of the grounding potential metal layer 11 and the metal lead 15 and a capacitor. Parallel connection of capacitors allows an impedance at the grounding potential terminal to be reduced extremely and only a slight voltage change to be generated at a terminal of a side of the chip 1. Since an impedance at the grounding potential terminal is extremely low, generated noise voltage maintains a small value even if the amount of current, current change rate, etc., are large, thus preventing malfunction from occurring.
