Title: Method and device for controlling welding current of spot welding machine
Inventor: MATSUMOTO HIDEO
IPC: B23K11/24
Filed: 1990-05-16
Abstract: PURPOSE:To improve welding quality by monitoring expansion of materials to be welded by generating an actual nugget to control the welding current in welding current control of spot welding. CONSTITUTION:In spot welding which is performed by controlling the welding current carried to the materials 10 and 11 to be welded held between electrodes 12 and 13 so that the specified nugget diameter is formed, the interval displacement quantity between both electrodes is measured after the welding current flow is started and control is executed so that the current flow is finished when it attains the predetermined reference quantity corresponding to the nugget diameter generated properly.

Title: Signal discriminating device
Inventor: WAKIMOTO KINGO
IPC: G06F17/40
Filed: 1988-05-19
Abstract: PURPOSE:To discriminate contents of signals more than the number of signal terminals by applying the output of a flip flop(FF) for main discrimination to respective signal terminals through a control signal terminal of a selector and 3-state buffer circuits. CONSTITUTION:In case of discriminating an operation signal for a dip switch 1a, a control signal SS is applied from a CPU to an FF 9 for sub-discrimination. Consequently, a 4-1 selector is disabled, the 3-state buffer circuits 10a, 10b, 10c are enabled by an output from an inverter 11 and an AND circuit 12 is also enabled. Then, a command signal S is applied from the CPU to the main discrimination FF 5 and output signals 5A, 5B, 5C are respectively set up to '1' and applied to the control signal terminals S11-S13 of an 8-1 selector 8. The 8-1 selector 8 selects the dip switch 1a, fetches its operation signal to an input terminal C17 and applies its output signal Y to a signal terminal D to fetch the signal Y to a signal deciding device 3. Since the AND circuit 12 has been already enabled, the inputted operation signal is applied to an OR circuit 13 and the output signal of the OR circuit 13 is applied to a 3-state buffer circuit 6. When a reading command signal RC is applied from the CPU, the inputted operation signal is outputted to the CPU and the CPU reads the operation signal.

Inventor: SHIBATA MINORU
IPC: H05K1/18
Filed: 1993-05-26
Abstract: PURPOSE:To provide a socket which can be mounted easily on a double side mounting type printed board surface. CONSTITUTION:A socket has a frame 1 and contacts 2 which are arranged at the same pitch with a plurality of lead legs 3a of an IC3 and are derived from the frame 1 while having a surface mounting piece 2a situated on the same plane so as to be mounted on a surface of a conductive circuit pattern 4a arranged on a surface of a prined board 4.

Title: Magnetic recording and reproducing device
Inventor: KANAZAWA YOSHIKAZU
IPC: G11B5/02
Filed: 1987-05-20
Abstract: PURPOSE:To prevent crosstalk by providing a switch which short-circuits the coil on the fixed side of a rotary transformer, which corresponds to a rotary head unnecessary for recording at the time of recording, with respect to electric signal. CONSTITUTION:A fixed side 6 of a rotary transformer 7 corresponding to rotary heads 1 and 2 which are not used for recording in the long-time mode is grounded by closing a standard mode reproducing switch 18 and standard mode recording switches 16 and 17. Consequently, the crosstalk from a coil 63a on the fixed side 6 of the rotary transformer 7 to a coil 62a is reduced, and a current does not flow to the rotary head 2, and a fear that the track recorded by the rotary head 3 is demagnetized is resolved. At the time of recording in the standard mode, not only switches 16 and 17 but also long-time semimode recording switches 19 and 20 and a long-time mode reproducing switch 21 are closed. Thus, the crosstalk in the rotary transfer at the time of recording is suppressed.

Title: Automatic gain controller
Inventor: SAKAI TOSHIYUKI
IPC: H03G3/20
Filed: 1991-04-26
Abstract: PURPOSE:To obtain a high speed operation type automatic gain control circuit compatible even with an input signal having a wide level fluctuation with respect to the automatic gain controller used for an optical reception circuit of an optical LAN(local area network) or the like. CONSTITUTION:An error ratio of an output signal of an AGC amplifier 12 is measured by an error ratio measurement section 13. A control section 14 adjusts a level of an input signal to the AGC amplifier 12 by varying the attenuation of a variable attenuator 11 so that the error ratio reaches a range not deteriorated from a prescribed value. The control direction of the attenuation (increasing/decreasing) is discriminated based on an AGC voltage of the AGC amplifier 12, for example. Thus, since the AGC dynamic range of the AGC amplifier 12 is enough to be a narrow range, the high speed operation is attained.

Title: Manufacture of thin-film circuit by periodic reverse electrolyzing method and thin-film circuit board, thin-film multilayer circuit board and electronic circuit device using the same
Inventor: INOUE TAKASHI
IPC: H05K3/40
Filed: 1994-06-08
Abstract: PURPOSE:To make it easy to make a thin-film circuit multilayered and to improve a component density sharply by applying electroplating to a dielectric surface of the thin-film circuit by a periodic reverse electrolyzing method. CONSTITUTION:When a current ic on the minus side flows, a phenomenon of cathode electric deposition (deposition of a plating film) is brought about on a base holder and a base. When a current ia on the plus side flows, on the other hand, a phenomenon of cathode dissolution (dissolution of the plating film) is brought about. According to this periodic reverse electrolyzing method, in other words, the deposition of the plating film proceeds on the surface of the base during a time Tc when a cathode current flows, while the dissolution of the plating film proceeds on the surface of the base during a time Ta when an anode current flows. For instance, a waveform of (b) is obtained by putting prescribed pauses T1 and T behind a cathode current pulse and an anode current pulse in an inverted pulse waveform of (a) respectively. Fig. (c) shows an asymmetrical sine wave (AC-DC superimposed wave) and the rise and fall of a current are gentle therein.

Abstract: PURPOSE:To eliminate the overhead that is produced when a conditional code CC is set in a post-process by setting the CC so far carried out while the post- process is carried out by a microprogram through an arithmetic operation of the 1st operand +0 performed by hardware before an operation. CONSTITUTION:A control part worked with 4-phase clocks T0-T4 and registers 510-518 are set with T1 together with registers 519 and 51A set with T2 respectively.

While a signal 56 sets the secondary command to the register 514. The registers 510-513 show the arithmetic stages. The secondary command of the vector instruction is stored in the register 514 when the instruction is started. The secondary command is not changed at the register 514 until the next instruction is delivered and then turned into the control signal of an arithmetic part. The registers 518 and 515-517 are started before an operand designated by an instruction is calculated in an arithmetic stage of a dummy started when the vector instruction is started. A signal 58 serves as a set signal of a CC register.
