Title: Packaging stem for semiconductor device
Inventor: INOUE TADAAKI
IPC: H01P5/08
Filed: 1988-05-30
Abstract: PURPOSE:To reduce the area of a monolithic microwave integrated circuit (MMIC) chip, and to curtail cost by forming a dielectric layer between a conductor for grounding and a terminal for supplying a bias. CONSTITUTION:A wide ceramic substrate 70, both surfaces of which are metallized previously, is bonded onto a metallic plate 60 as the conductor for grounding of a packaging stem. A section to which a terminal for supplying a bias is fitted previously is notched beforehand in the ceramic substrate 70 at that time. A tabular dielectric 80, both surfaces of which are metallized and which has excellent high-frequency characteristics, is cemented onto the metallic plate 60 so as to be fitted to the notching section of the ceramic substrate 70, and regions corresponding to the notching section in terminals 14, 14 connecting a high-frequency bypass capacitor are widened previously. Accordingly, the bypass capacitor need not be formed to MMIC chip itself, thus reducing the area of the chip, then improving yield with the diminishing of the area of the chip.

IPC: H04N5/445
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To reduce a printing cost without missing image data requiring emergency by immediately displaying the image data and a message at the display part of a television receiver when a FAX equipment receives the image data. SOLUTION: When an operator operates the operation part 18 of this video synthesizer 2 and sets the synthesizer 2 to a FAX display mode, a CPU 8 displays an operation mode to the display element of a display part 17. Then, the CPU 8 outputs information signals from a tuner part 12 to the television receiver 3 and reproduces video images and sound to the receiver 3. In the state, the CPU 8 monitors a modem part 16 at all times through a data bus 9 and an I/O interface 10 and judges whether or not the FAX is received by FAX control signals. When FAX reception is ended, the CPU 8 develops black and white dot data obtained by performing data expansion from code data stored in a memory part 14 as a sheet of image data in the memory part 14 and transfers them to a video signal preparation part 15.  Then, the preparation part 15 synthesizes video signals from the dot data and outputs them to the receiver 3.

Filed: 1984-06-27
Abstract: PURPOSE:To observe a visible, stereoscopic color video with continuity by arraying sequentially video sources in a zigzag and narrowing an array interval of the video source. CONSTITUTION:A convergence device 32 of a blue video tube 29 of a video source 26 at the upper side is positioned below a fixed main body 39 of a video source 27 at the lower side, while a convergence device 38 of a red video tube 34 of the video source 27 at the lower side is positioned above a fixed main body 31 of the video source 26 at the upper side. Thus video sources 40-44 can be arrayed vertically in a zigzag. Accordingly an interval of the video source can be narrowed in the horizontal direction, and moreover a vertical inclination can be smaller. As a result, when an observer moves in the Q direction gradually, right and left eyes are positioned at three places denoted by a group of 48 and 46, that of 49 and 47 and that of 50 and 48. Videos from the video sources 40-44, which can give an appropriate video to the observation, are observed, and a stereoscopic color video can be obserbed continuously.

Title: Sensor line type temperature sensor incorporating fault position detecting function
Inventor: HANE YOSHINARI
IPC: G01K11/06
Filed: 1978-10-30
Abstract: PURPOSE: To ensure an accurate detection of the fault position by flowing the current in the amount according to the length of the sensor line up to the short-circuit position to each ammeter through the short circuit of the sensor line due to the abnormal overheat.  
     CONSTITUTION: When the short circuit is caused to the metal wires each other of the insulating wire incorporated at the X-marked position of sensor line 1 and due to the abnormal temperature, the current flows from DC power source 5 in the route of ammeter A 1 →short circuit point→terminal 7 and in the route of ammeter A 2 →terminal 6'→short circuit point→terminal 7' respectively. With this composite current, relay R operates to give the abnormal temperature alarm. Here the distance of the short circuit side is referred to as l and the known wiring length of line 1 is L each. As a result, if the conductor resistance of line 1 is set as R 1 =ρ×l/S and R 2 =ρ×(2L-l)/S along with the current defined as I 1  and I 2  respectively at distance l and 2L-l, I 1 /I 2 =R 1 /R 2 =(2L-l)/l is obtained with distance l=2L/ (1+I 1 /I 2 ) respectively. Thus the faulty position can be detected accurately by calculating the ratio of the current measured by ammeters A 1  and A 2 .

Filed: 1995-05-01
Abstract: PURPOSE: To generate a liquid crystal driving signal by reducing the number of times of input data transition, decreasing a power consumption and also using low transition input data. CONSTITUTION: Difference data that identify presence or absence of a difference by comparing a picture data of a present horizontal scanning line with that of the immediately preceding line are inputted to a data transfer circuit 16 and then are successively shifted and stored for each picture element.

IPC: H01J9/14
Filed: 1981-08-26
Abstract: PURPOSE:To simplify a replacing and assembling work of a mask and a frame by reducing generation of a splash and a quantity of pressure marks inside of the frame when welding a spring into a frame. CONSTITUTION:When welding a spring into a frame 1, chrome copper is used as an electrode material for an outside welded electrode 3 and a tungsten silver compound is used as the electrode material for an inside welded electrode, while in respect of an area of the electrode end part the inside-welded electrode 4 is larger than the outside-welded electrode 3. Accordingly, current density (current/area) in an inside contact face is smaller than in the outside, while generation of splashes is less in the inside. Further hardness of the inside-welded electrode 4 is larger than that of the outside-welded electrode 3 so as to be able to prevent generation of a hollow of the inside welded electrode 4. In case also the inside and the outside are applied by the same pressure, the contact face of the inside-welded electrode 4 is large so that pressure per unit area for the frame 1 is small and a pressure mark of the electrode in the inside face becomes small.
