Title: Partial electroless-plating method, electro-optical device and its production
Inventor: ODA KOICHI
IPC: C23C18/31
Filed: 1990-02-13
Abstract: PURPOSE:To easily form a partial metallic layer by electroless plating at a low cost by dipping a substrate with the part not to be plated masked with a removable masking material into an electroless-plating soln. to form a plating layer and then removing the masking material. CONSTITUTION:The part of a substrate not to be plated is previously masked with a removable masking material. A glass sheet, tape, photoresist ink, etc., are used as the masking material. The substrate is then dipped in an electroless- plating bath to form a plating layer. Ni-P plating, Au plating, Ni-B plating, etc., are exemplified as the plating. After the plating layer is formed, the masking material is removed by detachment, stripping, elution, etc. A metallic layer is partially formed by electroless plating in this way. An electrode consisting of an In2O3-SnO2 transparent conductive film is formed on a glass substrate by this method, and an excellent electro-optical device is obtained.

Here, as the driving signal of the motor 2 created by a rotation stop signal at the circuit 8, its potential is changed in the positive and negative directions. That is, its polarity is changed in the positive and negative directions as the potential of the driving signal supplied to a driving signal supplying terminal and converged to 0V finally.

Title: Memory read error detecting system
Inventor: KUBOTA TOMOAKI
IPC: G06F11/10
Filed: 1988-02-12
Abstract: PURPOSE:To detect an error even when data is read from an erroneous memory unit by providing an inspection circuit to inspect coincidence with a unit number to be inputted by being added to read data. CONSTITUTION:When a CPU 1 requests the memory unit 2 to read the data, the read data is transferred from a memory array 3 to an output register 5. At that time, the unit number kept by a unit number holding circuit 4 is added, and afterwards, it is transmitting to a data bus 9. The CPU 1 fetches the data from the bus 9 into an input register 6, and transmits it to a data processing part 7, but at that time, it takes out the unit number in the data and transmits it to the inspection circuit 8. The circuit 8 holds an expected value prepared at the time when the unit 2 is requested to read the data, and it is compared with the inputted unit number number. Thus, when the data is read from the erroneous unit, the circuit 8 can detect that it is the error.

Filed: 1992-02-18
Abstract: PURPOSE:To easily magnify a screen by providing a means for enlarging a screen display in a horizontal direction and a means for enlarging the screen display in a vertical direction by displaying the prescribed number of horizontal line by delayed signals. CONSTITUTION:A start pulse and signals PHI1 to PHI3 are the same in timing, when the B side of selectors 18, 19 are selected in a segment driver 10. Then, a signal QY0 and signal QY1, and a signal QY2 and signal QY3 attain the same values. An output signal Y0 and output signal Y1 and an output signal Y2 and output signal Y3, therefore, attain the same level after a specific signal HS is outputted. The screen is thus enlarged double in a horizontal direction. The enlargement in a vertical direction is executed by superposing and forming the signal delaying the signal HS to be supplied to a common driver to the original waveform by using a timing adjusting circuit without changing the common driver. The delayed signal HS is required to exist during horizontal blanking display. As a result, two pieces each of horizontal lines are displayed and the screen is enlarged double in the vertical direction.

Abstract: PROBLEM TO BE SOLVED: To efficiently transfer data from a host to a peripheral device. SOLUTION: An external bus control part 212 in the host stores picture data to be transferred in a butter 104 and encodes the picture data by an encoding #1 or #2 in accordance with the characteristics of the picture data. The characteristics of the data are discriminated by judgement whether a correlation value between a reference line formed in each prescribed number of data and a noticed line is more than a fixed value or not, #2 encoding for executing >=2 encoding when the correlation value is more than the fixed value or executing #1 encoding when the value is not more than the fixed value calculates a difference between the noticed, line and the reference line and encodes the difference by run length encoding or the like. In the case of #2, the noticed line is encoded as it is.  In the case of color picture data, a specific color plane is used as a reference instead of the reference line and other planes can be encoded by an encoding method for determining them in accordance with correlation with the reference plane.

Filed: 1983-02-28
Abstract: PURPOSE:To prevent the thermal deformation of chillers and the consumption owing to damage in vacuum casting of a chilled casting by improving the mounting and recovery of the chillers. CONSTITUTION:Cam patterns 1 are arrayed in parallel on a pattern plate, and a series of chillers connected with several pieces of chillers 2 having the same shape by means of connecting bars are mounted on the cam patterns 1. A plastic film which is softened by heating is put on the pattern plate and the film is forced into the deep and narrow groove parts between the adjacent chillers by means of plugs. The film is then brought into tight contact with the pattern plate by vacuum suction from the pattern plate side to fix all the chillers 2 to the pattern plate. A molding flask is put on the pattern plate and dry sand is packed therein and the film is further put thereon. The sand is solidified by vacuum suction of the molding flask inside. While the inside of the casting mold is kept evacuated in this state, a molten metal is cast therein and after the molten metal solidifies thoroughly, the vacuum is released. Then the sand in the molding flask flows out of itself and the product and the chillers remain in the flask.
