Title: Circuit board
Inventor: KANEKO TADAO
IPC: H01L23/12
Filed: 1992-04-07
Abstract: PURPOSE:To form metal thin films on the surface and both side of the circuit board and perform wiring work, prevent disconnection on both side planes of a circuit board and improve high-frequency characteristics by permitting both shoulders of the circuit board to be of inclined surfaces or curved surfaces and metallizing the whole one side as an earth plane. CONSTITUTION:After processing a groove on a transparent quartz board 1 by dicing, curved surfaces 3 are formed on the both shoulders of the protruding part. Metal thin films 4 are formed on the front surface and the both side surfaces. For the shoulders 7 and 8, wirings are formed by dry etching after forming a photoresist pattern. After forming a photoresist pattern 13 according to the wirings on the shoulders, wirings are formed also on the side surfaces by dry etching. A fully metallized part is provided on the one side surface as an earth surface and a circuit board is manufactured. Thus, leakage of an electric signal between the adjacent electrodes caused by the mutual inductance is suppressed by forming the metal thin films on the front surface and the both side surfaces of the circuit board and forming the wirings.

IPC: H04B7/208
Filed: 1980-06-24
Abstract: PURPOSE:To receive a signal with lower level, by eliminating the level difference after AGC to a number of wave signals. CONSTITUTION:An amplitude limiter 10 decides the upper limit of the signal amplitude passing through a band pass filter 9, and this is done by a saturation amplifier such as differential amplifier, which acts as an amplifier to a low level signal and saturates to a high level signal to be limited to a given level. A plurality of signals level-limited with amplitude limiters V1-Vn corresponding to band pass filters F1-Fn, are synthesized at a synthesis circuit 11 and transmitted to a transmission section. Modulation is made at the section, but since the signal level is arranged for each signal with the amplitude limiters V1-Vn, uniform phase modulation is made  to each signal and transmission is made to the earth with the teansmission antenna  section.

IPC: H03K3/84
Filed: 1988-04-08
Abstract: PURPOSE:To generate pseudo random number sequence having uniformity with a high level and to perform logical analysis by generating the same pseudo random number repreatedly by enabling the pseudo random number to be generated only by a shift register having a fly-back circuit. CONSTITUTION:When a random number request signal is generated, a shift signal generation circuit 17 generates a shift signal, and changes the output values of shift register circuits (11-13) by shifting via exclusive OR circuits 14 and 15 and an inversion circuit 16. A multiplexer 18 receives the output of 16 bits of the shift register circuits (11-13), and selects eight bits by a bit selection indication signal and outputs them as a random number. In such a way, it is possible to generate the pseudo random number having the uniformity with the high level with simple constitution, and to generate the same pseudo random number repeatedly, and to perform the logical analysis.

Abstract: PURPOSE:To enable the scanning homogeneity to be reproduced constantly by enabling a homogeneous scanning of the entire surface of a target to be performed without any adjustment by means of a scanning trianguar-wave signal generating circuit which is a part of an electrostic X-Y beam scanning device used for ion injection. CONSTITUTION:Clock pulses sent from one block generator 1 are introduced into an n1-counter 2 and an n2-counte 3, and are counted simultaneously. The outputs of the counters 2 and 3 are connected, respectively, to the address inputs of a first and a second ROM4 and 5. In the memory locations of the ROMs 4 and 5 containing, respectively, 0 to (n1-1) addresses and 0 to (n2-1) addresses, data used for producing one cycle of step-like triangular waves by combining the data with a first and a second D/A converter 6 and 7 connected, respectively, to the outputs of the ROMs 4 and 5 are written. The signals of a first and a second triangular-wave output 10 and 11 are amplified before they are applied, respectively, to an X-direction and a Y-direction scanning electrode. As a result, adjustment work of the original frequency becomes unnecessary, and the scanning homogeneity can be constantly reproduced.

Abstract: PURPOSE:To measure a potential stably by supplying an extremely small quantity of charge to an electrochromic layer. CONSTITUTION:This describes the measurement of the potential of an electrochromic (EC) layer 6 when the EC layer 6 is in a coloring state. Firstly, an EC layer 3 used as a decoloring electrode is decolored as usual and after constant charge is supplied to the EC layer 3 via a charge controller, its potential is measured to obtain a value which corresponds to the potential of the EC layer 6. In this process, a dotted line in the figure shows the real potential of the EC layer 6 and an this method, potentials a little bit lower than the real potential are measured as measured values in almost all cases. Controlling the quantity of charge applied to the decoloring electrode reduces differences between the measured values and real potential.

IPC: G11B7/2534
Filed: 1987-04-08
Abstract: PURPOSE:To prevent deformation of a composite hub for optical disk and occurrence of cracks in the hub, by constituting a material for making the hub in such a way that a 3-30wt.% multistage polymer is mixed with the same kind of a base resin as that used for constituting the substrate of an optical disk. CONSTITUTION:The resin of this composite hub which is a molded product of a resin containing a metallic plate is constituted by mixing the 3-30wt.% multistage polymer with the same kind of the base resin as that used for constituting the substrate of optical disks. Polycarbonate or polymethyl methacrylate is used for the base resin. Since the same kind of resin as that used for constituting the substrate of the optical disk is used as a principal material, the coefficients of a thermal expansion of the hub and disk substrate become almost equal to each other and any stress produced in the hub due to a difference in coefficient of thermal expansion is absorbed into the material. Therefore, deformation of the hub or occurrence of cracks in the hub can be prevented.

Title: Extra fine diameter carbide drill
Inventor: OHATA KOKICHI
IPC: B23B51/00
Filed: 1989-04-07
Abstract: PURPOSE:To have a surface layer having fine adhesion, a small coefficient of friction and fine abrasion resistance by forming a nitride with the evaporated metal in the surface so that a density of the nitride is reduced in order from the surface to the inside, and setting a ratio of X-ray diffraction peak values from the nitride surface and the surface at more than 1.0. CONSTITUTION:A metal is evaporated to be adhered in a cemented carbide surface and while the nitrogen ion is irradiated to form a nitride with the evaporated metal in the surface, and the nitride is reduced in order from the surface to the inside. When a ratio of the metal atom to be evaporated and the ion to be filled is controlled to change a ratio I200/I111 of X-ray diffraction peak values from the nitride surface 100 and a surface 111, a hardness and a friction coefficient are changed as the figure shows. When the friction coefficient is reduced, an effect by the reduction of the friction efficiency is remarkably large though an abrasion loss is reduced and the hardness is reduced. An extra fine diameter drill having fine adhesion, a small friction coefficient and fine abrasion resistance can be obtained by setting the ratio I200/I111 of the X-ray diffraction peak values at more than 1.0.
