Title: Compressor drive
Inventor: ADACHI KOSAKU
IPC: H02P6/21
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To suppress a period, while valve noise is generated from a compressor when its operation is started within a short time and secure the start of the operation of the compressor. SOLUTION: The starting pattern of a compressor comprises an initial duty which determines an application voltage, when the compressor operation is started and an acceleration duty which determines a voltage rising rate thereafter. A drive has a starting pattern consisting of three patterns. After the starting pattern which was employed last time and the operation state was successful with it is initially set, the operation is started (S1 and S2). Every time a voltage maintaining timer goes into a time up state of 50 ms, an acceleration duty is added to the initial duty (S6). If the acceleration does not reach 30 Hz when a failure decision timer with a timer of 10s is up, it is decided that the start is failed (S9). If the start failure occurs three times in succession, the next starting pattern whose starting time is one step longer than the first one is employed, and operation is re-initialized (S18). If the start fails even with longest starting pattern whose starting time, the compressor operation is stopped permanently.

Title: Alignment-mark
Inventor: USHIYAMA FUMIAKI
IPC: H01L21/3213
Filed: 1988-03-23
Abstract: PURPOSE:To improve the accuracy of alignment of a wiring process by forming a wiring layer onto a recessed section or a projecting section with a stepped section composed of at least one part of a first oxide film shaped onto a substrate and the whole layer of a second oxide film, an etching rate of which is smaller than the first oxide film. CONSTITUTION:In a semiconductor device with wiring layers having two-layer structure, an inter-layer insulating oxide film (PSC) under the first layer wiring layer is formed onto a substrate 11 as a first oxide film 12, and an inter-layer insulating oxide film containing no impurity shaped between the first wiring layer and the second wiring layer is formed as a second oxide film 13. Etching in a forming process for a contact hole aiming at the connection of the first and second wiring layers to the second oxide film 13 is conducted up to the whole layer of the second oxide film 13 and one part of the first oxide film 12, thus shaping a recessed section. A second layer wiring layer 14 is formed onto the recessed section, thus acquiring an alignment-mark. Accordingly, the accuracy of alignment can be improved without increasing manufacturing processes.

Abstract: PURPOSE:To increase the resolution of an image for either the entire area of a photoelectric cathode or its central area by specifying the sectional surface of the photoelectric cathode and making either an imaging surface in the entire area or that only in the central area almost flat. CONSTITUTION:A photoelectric cathode 16 is installed on the window 15 of a vacuum encircling case 1 and an anode 11 and a fluorescent screen 12 are installed on the discharge window 14 of the case 1. And, focusing electrodes 6-9 are installed between the windows 14 and 15, thereby making an X-ray image tube. The median curvature radius of the sectional surface 21 of the cathode 16 increases from the center of the surface 21 up to 1/2-4/5 of its diameter apart from the center in a degree more than that proportional to the distance from the center. It increases from the above point toward the periphery of the surface 21 in a degree less than that proportional to the distance from the center. Therefore, when only the central area of the cathode 16 or the entire area of the cathode 16 is observed, there is only a minimal difference in focusing effect between the electronic orbits 28 and 29 and the central electronic orbit 30, thereby achieving good resolution for both visual fields.

Abstract: PURPOSE:To reduce the erroneous detection of a synchronizing signal by constituting the synchronizing signal so as to be a pulse string of 50% duty, and during the receiving period of data obtained after the detection of the synchronizing signal, locking the operation of frequency dividing circuit. CONSTITUTION:The rise of a transmission signal TDT is detected by a detecting circuit 4 and its detecting signal TDTE is inputted to the reset input RS of the frequency dividing circuit 5 through an AND gate 9 to reset the signal TDTE.

Abstract: PURPOSE:To prevent an earth detection device from being subjected to insulation breakdown and to improve reliability, by connecting a line shortcircuit detection resistance of a line shortcircuit detection device to the earth side of a limiting resistance of the earth detection device. CONSTITUTION:A line shortcircuit detection device 40 connects series circuits of a voltage dividing resistance R1 and a line shortcircuit detection resistance r1, which is a variable resistance, respectively to a three-phase circuit of an AC excitation circuit 37.

Both terminals of the line shortcircuit detection resistance r1 and the earth detection circuit resistance r2 are introduced to a detection section 6 respectively. Since the line shortcircuit detection resistance r1 is connected to the earth side of the limiting resistance R2, no potential of an isolation amplifier of the line shortcircuit detection device 40 will be so high against the earth as before that the occurrence of shortcircuit there can be prevented.
