Title: Electronic circuit pattern and manufacture thereof
Inventor: MATSUDA NAGANARI
IPC: H01L23/52
Filed: 1990-09-04
Abstract: PURPOSE:To enable the manufacturing process of a circuit pattern to be remarkably lessened in man-hours and simplified by a method wherein a thin film is patterned into two parts, a low surface resistance part and a high surface resistance part, a resistance ratio is set lower than a prescribed value, and the thin film is formed of metal oxide of the same composition. CONSTITUTION:An ITO film is formed on a PET film as thick as 500Angstrom  through a reactive sputtering method. The film has a surface resistance of a few MOMEGA/ square or above and a light transmittance of 85% the same as a peroxide material. The film concerned is irradiated with laser rays 6. The effective output power of a YAG laser is 3W, a processing speed is 0.5m/min, and a laser spot is 50mum in diameter. In result, the irradiated part 7 is 500OMEGA/square and 2.5X10<-2>OMEGAcm in surface resistance and resistivity respectively and 1/10<4> as small in resistivity as the non-irradiated part 8. The film is 85% in light transmittance, so that it is both transparent and conductive. By this setup, the irradiated part 7 is made to have a 4 conductive characteristic very different from that of the non-irradiated part 8, whereby a transparent electrode circuit pattern can be formed on a PET film.

Title: Digital broadcast receiver
Inventor: KAWABATA YOHEI
IPC: H04N5/445
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To attain stable on-screen display by selecting an external synchronization mode encoding with external synchronization reference from its own synchronization mode when interruption of a broadcast radio wave is sensed. SOLUTION: A dot counter 1952 is configured with a counter in which a horizontal dot number is used for an adic so as to count one horizontal dot number and a ripple carry-out RCO is outputted. When no horizontal synchronizing signal H is received, an internal synchronizing signal INTH is outputted. A horizontal synchronization counter 1953 is made up of a counter using a horizontal scanning line number for a vertical period as its adic, then the counter outputs an internal synchronizing signal INTV when no vertical synchronizing signal V is received. Thus, a synchronization generating section 195 receiving signals H, V from a video encoder provides outputs of th signals INTH, INTV of the same phase and the counter section 195 provides outputs of signals INTH, INTV from the internal counter when no signal H, V are received.  Then on- screen information is generated based thereon and the indication is made stable.

Title: Electron beam exposing method
Inventor: ABE TOMOHIKO
IPC: G03F7/20
Filed: 1992-09-03
Abstract: PURPOSE:To provide highly accurate block exposure by adjusting an electron beam so that the beam can be perpendicularly incident to a stencil mask. CONSTITUTION:Both an X and Y patterns have several tens of lines, with the lines and spaces between each line having the same width of 5mum, and the aspect ratio of through holes are set at 4. A beam simultaneously irradiates about 40 lines and an incident mask deflector makes the beam to incident to the X pattern 12 by deflecting the beam toward the position of the X-pattern 12. The current value of a sample becomes the maximum at an incident beam position at which the plane of incidence becomes parallel to the X-direction and the direction of the beam becomes perpendicular to a stencil mask surface. Accordingly, the deflector 1 is adjusted while the current value of the sample is measured with an ammeter 14. The deflector 1 is adjusted in the same manner even when the plane of incidence is parallel to the Y-direction. Therefore, highly accurate block exposure can be obtained.

Filed: 1987-09-21
Abstract: In a liquid crystal display, each pixel is formed of four separately energisable areas I, II, III, IV which have relative light outputs in the ratio 1:2:4:8 respectively, thereby allowing a range of 16 grey levels to be achieved by appropriate selection of areas. Each of the areas has a number of segments, which are spaced-apart but concentrically arranged, in order to have the same average position, so that different bit patterns cause the pixel to change brightness only, without any apparent positional change.

IPC: G02F1/055
Filed: 1998-08-21
Abstract: PROBLEM TO BE SOLVED: To obtain an optical shutter element small in size and capable of being driven with a low voltage and easily manufactured by providing the end part of a ceramic plate having an electrooptic effect with plural slits forming a metal electrode and transmitting light through parts pinched with the electrodes. SOLUTION: This optical shutter element consists of a structure in which the end part of a ceramic plate 1 having an electrooptic effect is provided with plural slits forming a metallic electrode 2. In the element, a voltage is applied between a pair of the metallic electrodes 2 pinching a ceramic part and light beams are transmitted through parts pinched with a pair of the electrodes almost in parallel to the surface the electrodes 2. Since the light beams are not transmitted through any part in which no electric field is applied, the electric field effectively acts to be able to lower the driving voltage for the element. The design of the element, such as the gap of the slits, the thickness of ceramic plate 1 and the depth of the slits can freely be selected in accordance with the required performance for an optical shutter and within the range of cutting accuracy.  Also, as the material of the ceramic plate 1, PLZT (lead (plumbum) lanthanum zirconate titanate) is suitable.

Abstract: PURPOSE:To eliminate a wiring shortcircuit and so on due to the peeling residues of unnecessary wiring materials and to improve the manufacturing yield of a metal pattern by electrically fuse-cutting a metal film adhered on the side surface of a resist pattern. CONSTITUTION:A pair or probes 5 are brought into contact between a metal film 3 and a metal film 4 for cutting a film adhered on the side surface of a resist pattern 2 and a current is supplied by a power source 6 gradually increasing a voltage E from zero. When the voltage reaches the prescribed voltage, the film adhered on the side surface of the pattern 2 is fuse-cut and the current ceases to flow between the metal films 3 and 4. This can be known by monitoring the value of an ampere meter 7. Then, a substrate 1 is dipped in a photo resist release agent and when the resist pattern 2 peeled, the metal film 3 applied on the resist pattern 2 is peeled and the metal film 4 only on the substrate 1 remains as an electrode wiring.

Abstract: PURPOSE:To prevent electrons from leaking out to a substrate by forming each element of a capacitive coupling, a rectifier circuit and a smoothing circuit, in a well of conductivity type inverse to the semiconductor substrate, and applying a power supply voltage to the well in the manner in which the well and the semiconductor substrate are inversely biased. CONSTITUTION:A ring oscillator 26 generates a ripple voltage by utilizing both of power supply voltages Vcc and Vss, and said ripple voltage is delivered to a capacitive coupling 23, by which DC component of the ripple voltage is cut off. AC voltage outputted from the capacitive coupling 23 is delivered to a rectifier circuit 28; the positive half cycles are cut off by a diode constituting the rectifier circuit 28, and negative half cycles only are delivered to a smoothing circuit 29; the wave form is flattened by the smoothing circuit 29 thereby obtaining a substrate bias voltage of a prescribed value. Wells 22a, 22b and the semiconductor substrate 21 are inversely biased by a substrate bias generating circuit constituted in the above-mentioned manner. As a result, electrons injected into the wells 22a, 22b are absorbed from the wells 22a, 22b, and prevented from leaking out to the semi conductor substrate 21, thereby enabling the miniaturization and the high density integration of an integrated circuit.
