Title: Manufacture of planar display panel
Inventor: MIYAHARA MAMORU
IPC: H01J11/34
Filed: 1987-04-07
Abstract: PURPOSE:To prevent discontinuity of an electrode pattern from occurring when a dielectric layer is formed, by using a copper etching solution to perform an etching process on the electrode pattern just after forming the electrode pattern. CONSTITUTION:An etching solution of ferric chloride or the like is used to perform a second etching process on the whole surface of an electrode pattern 34 which is formed in three-layer film structure of Cr-Cu-Cr. Abnormal exposed parts of a Cu film 32b, which are produced by over-etching of first and second Cr films, 32a, 32c, and the like on the electrode pattern 34, are removed by etching so as to obtain a minimum degree of exposure in which exposed parts of a Cu film 32b are hard to be thermally welded with low-melting-point glass. Thereafter, a glass substrate 31, on which the electrode pattern 34 of three-layer film structure is formed, is coated with low-melting-point glass in prescribed thickness by a screen printing method or the like, and next a firing process is performed. A dielectric layer 35 can be hence formed on the electrode pattern 34 of three-layer film structure, without occurrence of discontinuity of the electrode.

Title: Variable power projecting machine
Inventor: KAWAI NOBUYUKI
IPC: G03G15/041
Filed: 1986-04-15
Abstract: PURPOSE:To correct by a small movement, by correcting a variable power and a conjugate length by a small mutual movement in the separating direction of a through- lens and a mirror of its rear side or front side, at the time of the variable power extending from unmagnification to an enlargement or a reduction. CONSTITUTION:For instance, when the maximum enlargement copying is selected from an unmagnification copying state as shown in the figure, a motor is operated to a prescribed step in the enlarging direction, by which a through-lens 28 is moved to the maximum enlargement position shown by a virtual line extending from a full line position to the front side. By following it, the fourth mirror 10 is moved to the maximum enlargement position shown by the virtual line from the full line position by a cam, and a displacement to the maximum enlarged state and a correction of conjugate length therefore are executed. This variable power is accompanied with a large variation to an optical path length of the rear side of the through-lens 28 of the conjugate length, but it is attained by a small mutual movement in the separating direction of the through-lens 28 and the fourth mirror 10 of the rear side of the through-lens 28. Also, when the maximum reduction copying is selected, the motor 14 is operated to a prescribed step in the reducing direction, and said lens is moved to the maximum reduction position shown by a one point chain line.

Title: Inter-multi-point communication equipment
Inventor: FURUKAWA KAZUHITO
IPC: H04M3/56
Filed: 1991-04-18
Abstract: PURPOSE:To cancel an in-phase component between reception lines and to attenuate an echo signal by inverting the polarity of an echo signal fed back from a transmission line to the reception line and inputting the echo signal whose polarity is inverted to a voice mixer. CONSTITUTION:AND gates 109a-m input detection signals 207a-m of detection circuits 207a-m and selection signals 280a-m of a selector 111. Detection circuits 106a-m judge a voiced sound to trigger relevant selectors 110a-m. Only the voice of a talker selected by the selector 111 is inputted directly to a voice mixer 103 from a terminal A of the selectors 110a-m. Background tone or the voice of the talker which is not selected by the selector 111 is attenuated by attenuators 107a-m and noise is interrupted by limiters 108a-m and the result enters the mixer from a terminal B of the selectors 110a-m. Thus, production of a noise tone due to an undesired background tone and line noise or the like is prevented and the content of conversatio is made clear.

Abstract: PURPOSE:To perform recording operation easily and securely in operation observation, by relating a code from a keyboard and a clocking output to each other and by recording them on a freely detachable cassette tape, etc. CONSTITUTION:When a recording key S.R is operated, a latch signal is generated and an operation start time from a clocking circuit 3 is latched by a latch circuit 32 and also displayed on a display part 22. When the start of operation is indicated through successive operation on a keyboard 10, its code is latched by a latch circuit 12. A recording command generated by operating the key S.R again opens AND gates 42 and 44 to record the operation start and start time on the tape of a cassette 5. Similarly, when the 1st operation is completed and the switch S.R is operated twice each before and after the 1st assignment of work, the 1st work code is related to the clocking time and both are recorded on the tape of the cassette 5. For sequential operation, the data are recorded similarly, and the recording in operation observation is facilitated and secured through the simple constitution without using a stopwatch, etc.

Filed: 1989-04-06
Abstract: PURPOSE:To ease patterning by forming a film comprising a superconducting material on a substrate, covering the same with a mask comprising an oxidized insulating material and a high melting point metal material, and thermally oxidizing the same to oxidize only a region exposed from a mask window. CONSTITUTION:With a film 2 comprising a ceramic superconducting material formed on a substrate 1, a mask 3 of an oxidized insulator (or high melting point metal) with its pattern formation region including a window 4 provided through the same is brought into close contact with the film 2. Then, only a part exposed from the mask 3 is selectively oxidized by heating the film 2 in an atmosphere of oxygen and crystallized into a superconductor, while the region 2 covered with the mask 3 is left behind the intact as an insulator without being oxidized by strain produced at the boundary between it and the mask 3 and due to lack of oxygen. Accordingly, a superconducting film 8 of the same shape as that of a pattern of the window 4 of the mask 3 is formed on the substrate 1. Hereby, the ceramic superconducting film 8 is patterned maintaining its superconduction property.

Abstract: PURPOSE:To read the storage content of a ROM from a few input/output terminals even if the bit width of the storage content of the ROM is increased by incorporating an integrated circuit with 1-bit output ROM in a microcomputer. CONSTITUTION:An address counter 1 and a PROM 2 are arranged on one chip to constitute the integrated circuit 6 with 1-bit PROM. A microprocessor 5 fetches one bit of data of the PROM 2 and outputs a pulse incrementing the content of the address counter 1, fetches one bit of data of the PROM 2 again, applies packing it with the pre-fetch data and increments the content of the address counter 1. The operation above is repeated and when the width of the packed data is equal to the data width of the RAM 4, the microprocessor 5 loads the packed data to the RAM 4. Thus, the number of input/output terminals with the microprocessor 5 is decreased to only three.
