Inventor: TERASAWA HIROHARU
IPC: B41J2/175
Filed: 1983-12-15
Abstract: PURPOSE:To surely supply ink and at the same time to reduce the labor of operator, by a method wherein the operation of feed means and the output of alarm are worked for a fixed time by the output signal from a detection means, and at the same time when the amount of ink in a ink reservoir part does not reach a required amount after the fixed time has elapsed, another alarm output different from the former alarm output is worked. CONSTITUTION:As the pressure feed operation of ink is started, a timer circuit 21 is turned on and the timing of the maximum pressure feed time Tmax is started. However, the liquid surface 3A of ink only slightly rises and the detection level 3B of liquid surface is not reached. In that case, when the maximum pressure feed time has elapsed from the starting time point of pressure feeding, the timer circuit 21 is turned off, the pressure feed apparatus 11 being turned off thereby and the operation of pressure feeding is ended. Further, at that time, the lighting of a lamp 23 is changed to an intermittent flashing. By this change of alarm output, the fact that the ink tank 13 is vacant and its exchange is required, is reported to the operator.

Title: Method and device for measuring patternized structure
Inventor: DAVID SCHEINER
IPC: H01L21/66
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To provide a method and device for measuring parameters of a patternized structure. SOLUTION: A structure represents a grid having one cycle 12 comprising two adjacent elements 12A, 12B having different optical properties related to incident radiation rays. An optical model based on a few characteristics of the structure can determine theoretical data Dt, representing spectral intensity of an optical element of different wavelengths fully reflected from the structure, and at least one desirable parameter of the structure is computable. A substantially larger measuring region than a surface region of the structure provided by a grid cycle is irradiated by the incident radiation rays in the prescribed wavelength range. The optical element substantially reflected fully from the measuring region is detected, thereby obtaining measuring data.  The measuring data and theoretical data are analyzed to optimize the optical model, until they satisfy the conditions set previously by the theoretical data. If the conditions set previously are satisfied, at least one parameter of the structure is calculated.

Title: Video signal processing devicd
Inventor: YAMAGATA SHIGEO
IPC: H04N9/81
Filed: 1984-11-08
Abstract: PURPOSE:To realize the line simultaneity even when the S/N of line sequence signal is not good, by compensating the discontinuity of video signals using the 1st timing signal and by synchronizing line sequence signal by the control signal which is obtained by phase-shifting the 2nd signal which is reversed at each horizontal scanning period based on the 1st timing signal. CONSTITUTION:The output of DFF 19 becomes the control signal of SW 3, and the SW 3 is connected to I side when the control signal is in high level, and to G side when the signal is in high level. At this time, the skew- compensated line sequential color signal, namely horizontal synchronization signal which comes out of H terminal of SW 3 is inputted to an inverter 9. This horizontal synchronizing signal is formed by synchronizingly separated from the brightness signal of the skew-compensated video signal. The output of the inverter 9 is 1/2 demultiplied by DFF 16, and its output supplied to EXORs 17, 18. The switching of SW 1, SW 2 is controlled by the output signal of the WXOR 18. By this the line sequence color signal is converted into a color difference signal of color synchronization.
