Title: Data input and output circuit
Inventor: ANPO MASAHARU
IPC: G06F13/00
Filed: 1985-06-10
Abstract: PURPOSE:To eliminate the collision of data and to decrease the power supply noises in order to prevent the malfunctions of a data input/output circuit, by setting satisfactorily the level of a data input/output terminal to stop the output of data and then holding the data by a positive feedback means. CONSTITUTION:The data of an L level is supplied from another IC via a data bus which is connected by a bus terminator 53 when the data on an input/output terminal 52 is set at an H level. In such a case, an output buffer 51 already stops its operation and an output terminal is put under a high impedance state. The terminator 53 functions just to hold data and has the extremely small capacity for supply of current. Thus it is never feared that a large current flows between two data input/output circuits via the data bus. Here it is possible to set forcibly the terminal 52 of this input/output circuit at an L level by another data input/output circuit. Thus no collision of data occurs on the data bus.

Title: Programmable controller
Inventor: KUROKAWA NAOHIRO
IPC: G05B19/05
Filed: 1986-06-02
Abstract: PURPOSE:To easily attain usable and rapid arithmetic processing by reading out data arrayed immediately before the storing position of a leading sequence instruction in a user memory only by one byte just before the start of sequence operation and then starting the sequence operation. CONSTITUTION:The user memory 4 stores a sequence programs SPG and a CPU 3 executes arithmetic processing based on the SPG in accordance with processing procedure stored in a ROM 5 and stores the operated result in a data RAM 8. A step counter 12 is set up to an optional value by reading out an optional address from the memory 4 through a decoder 10 and a step counter control circuit 11. An I/O number signal with the constitution of a sequence instruction read out from a counter 12 or an address bus signal from the CPU 3 is selected by a selector circuit 14 and a signal from the circuit 14 or the signal read out from the counter 12 is selected by a selector circuit 13. When data arrayed immedately before the storing position of the leading instruction in the memory 4 only by one byte just before the start of operation, the counter 11 automatically counts up the value of the counter 12. Thus, rapid arithmetric operation can be attained by simple operation.

Title: Display device
Inventor: NAGASHIMA YOSHITAKE
IPC: H04N3/34
Filed: 1984-06-19
Abstract: PURPOSE:To obtain a picture of high picture quality in a display device using a cathode-ray tube, by converting discrete scan structure to apparent continuous arrangement by constituting a space low-pass filter in vertical direction to a horizontal scanning line. CONSTITUTION:In vertical deflection, high frequency noise signals are superposed on vertical deflection signals, and horizontal scanning lines make minute deflection in vertical direction. L1-Ln in the figure show horizontal scanning lines devoid of displacement in vertical direction. The beam spot of horizontal scanning lines make minute displacement at random by noise signals NS, and its probability of generation in vertical direction makes Gaussian distribution around horizontal scanning lines L1-Ln. Accordingly, the extent overlaps adjoining scanning lines, and probability distribution when composed becomes uniform as shown by a broken line. The value of amplitude of noise signals is adjusted to make this probability distribution uniform, and the maximum value is set not to exceed adjoining scanning line devoid of displacement. Thus, the space low- pass filter is constituted equivalently in the direction of vertical deflection, and the discrete scanning structure is converted apparently to continuous arrangement, and the picture quality is improved.

Title: Cooler of laser device
Inventor: MATSUZAKA FUMIO
IPC: H01S3/041
Filed: 1992-05-19
Abstract: PURPOSE:To prevent lowering of laser light generation efficiency by providing a cooler on a dielectric plate on the downstream side of a metal electrode 3 while providing a low dielectric constant band between this cooler and an electrode 3. CONSTITUTION:A cooler 7 for letting flow a cooling medium 8 to a dielectric plate 2 on the downstream side of a metal electrode 3 is provided while providing a low dielectric constant band 12 between the cooler 7 and the electrode 3. Accordingly, the electrostatic capacity between the cooler 7 and the electrode 3 can be reduced even when the cooler 7 having the high dielectric constant is mounted on the dielectric plate 2 so that a leakage current flowing from the electrode 3 to the cooler 7 is reduced. Then, the activity of the cooler 7 cools the dielectric plate 2 of the downstream side and laser gas is cooled. Thereby, damage due to temperature rise of the dielectric plate 2 can be prevented while preventing lowering of the laser light generation efficiency due to the temperature rise of laser gas.

Abstract: PURPOSE:To make a threshold low and to be long-lived by a method wherein a selenium diffusion part formed by diffusion from a current-blocking layer is formed on the side of the current-blocking layer inside a p-type clad layer. CONSTITUTION:A p-type clad layer 2 and a current-blocking layer 3 doped with selenium at high concentration are formed on a p-type GaAs substrate 1; after that, the blocking layer 3 is etched; a groove 10 is formed. Then, a p-type clad layer 4, an active layer 5, an n-type clad layer 6 and an n-type contact layer 7 are formed as a double heterostructure; after that, an annealing operation is executed; selenium as a dopant inside the current-blocking layer 3 is diffused into the p-type clad layers 2, 4. Then, electrodes 8, 9 are formed; a semiconductor laser is obtained. Since a part on the side of the current- blocking layer 3 of the clad layers 2, 4 has been reversed, a p-n junction is formed near the center of the clad layer 4; a leakage current is reduced; a low threshold can be realized.

Abstract: PURPOSE:To surely discriminate the presence/absence of a cassette tape from a remote location and to detect open tape of a magnetic tape, by providing a discrimination section which detects the number of revolutions of a take-up reel and produces an output when the number of revolutions is a reference value or over. CONSTITUTION:When a cassette tape is loaded in the recording or reproducing mode, an output of a frequency-voltage converting circuit 15 is lower than a reference voltage and no output is produced from a comparison circuit 16. Thus, even if an output from a discrimination circuit 14 is obtained, a gate circuit 17 is closed and no output appears at an output terminal 18. When no tape is loaded, an output from the circuit 15 is higher than the reference voltage, the comparison circuit 16 gives an output, the gate circuit 17 is opened and an output appears at the output terminal 18. Thus, the presence/absence of a cassette tape can be discriminated from a remote location.

Title: Detecting method for leakage at pipe line
Inventor: NAGAI YASUAKI
IPC: G01M3/28
Filed: 1981-08-11
Abstract: PURPOSE:To perform a rapid and reliable decision of a leakage at a pipe line, by a method wherein liquid to be conveyed is shut off by a pipe line, and a change rate in pressure is found based on two pressures to compare the change rates. CONSTITUTION:In case a leake test of a pipe line 1 takes place, liquid in the line 1 stops being conveyed, cut-off valves 2 and 3 are closed, and liquid to be conveyed is enclosed by a given pressure. An amount of a change in pressure of liquid produced for a given period of time is measured by a pressure measuring device 6. Then, with a reducing valve 4 opened, a part of the liquid is extracted from the pipe line 1, or the liquid is further implanted into the pipe line 1 by a pressurizing device 5. This causes reducing or increasing of liquid pressure in the line 1 to measure (6) again a change in the pressure of the liquid produced for a given period of time. Based on a difference in a pressure change rate in each inner pressure, the presence of leakage is decided.
