Filed: 1990-06-16
Abstract: PURPOSE:To allow the execution of optical AGC of a wide dynamic range to light input by controlling a directional coupler type optical switch in accordance with the output for monitor of a Y branch. CONSTITUTION:The directional coupler type optical switch 9 and the Y branch 10 for branching the output of the optical switch 9 are integrated on the same substrate 1 and the directional coupler type optical switch 9 is controlled in accordance with the one output of the Y branch 10. Namely, the light input from an optical fiber 3 for input is impressed with a control voltage in the directional coupler type optical switch 9, by which the light input is subjected to attenuation and branched. The light power is outputted to an optical fiber 4 for output. The output of the optical fiber 5 for monitor changes when the input changes. The control voltage of the directional coupler type optical switch part 9 changes according to the output change of a photodiode 7. Consequently, the output from the optical fiber 4 for output is always constant. The optical AGC circuit which can take the large dynamic range is obtd. in this way.

Filed: 1988-06-27
Abstract: PURPOSE:To facilitate manufacturing, to increase mechanical strength, and to generate a bias magnetic field with high efficiency in a vertical direction by combining a nonmagnetic slider and a U-shape head core after working them individually and independently, respectively. CONSTITUTION:The cross-sectional area of at least the foot part 16 with a small cross-sectional area of the U-shape head core 3 is decreased according to the approach of the cross-sectional area to an end face, and a comparatively large perpendicular magnetic field can be obtained by taking a sufficient interval between both end faces with the foot part 11 of the core with a large cross-sectional area.

Here, the U-shape head core 3 is formed in such structure that it is embedded in the slit part 9 of the nonmagnetic slider 2. In such a way, it is possible to secure sufficient reliability also in the mechanical strength.

Title: Part suction state detecting device
Inventor: NAGAI TOSHIAKI
IPC: H05K13/08
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To provide a part suction state detecting device that can detect the suction state of a wide-range part to be mounted with a simple configuration. SOLUTION: When an electronic component 27 being sucked by a suction nozzle 25 is a part with a fine pitch, the electronic component is irradiated with light from a back surface by lighting sources 28 and 28'. Otherwise, irradiation is made from a side by line light. On the optical axis of the line light, a dichroic mirror 23 is arranged, where the dichroic mirror 23 nearly transmits merely the wavelength of the line light and at the same time nearly reflects merely the wavelength of light from the back surface, and a luminous flux from the dichroic mirror is received by a two-dimensional sensor 24 for detecting the suction state of the part. In such a configuration, the image of the electronic component is picked up by lighting from the side or the back surface corresponding to the kind of the electronic component to be sucked.  In this case, the luminous flux from the side and back surface is selected for receiving, thus using a sensor for detecting the suction state of the part commonly for any electronic component.

Title: Communication unit
Inventor: SAKAMOTO KENJI
IPC: H04N5/00
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To avoid problems that too wide a waiting interval causes much time up to update and too short a waiting interval causes waste of power by varying the update interval on the basis of a received confirming signal. SOLUTION: A transmission control means 212 starts a transmission power control means 213 and the transmission power control means 213 supplies power to a transmission means 214. The transmission means 214 receiving power transmits an update request signal. That is, the transmission means 214 transmits the update request signal at each update interval stored in an update interval storage means 208. When no reply comes from a data transmitter 10 with respect to this update request signal, it is considered that the data transmitter 10 and a data receiver 20 are in a communication disabled state. Then an update interval revision means 207 changes an update interval to increase the interval.  Furthermore, in the case that a signal sent from the transmission control means 103 indicate 'no update data', the update interval revision means 207 revises the update interval to shorten the update interval.

Abstract: PURPOSE:To facilitate the adjustment by supplying a recording signal inputted from a rotary transformer to a differential amplifier circuit applying linear differential amplification via an input circuit having a low input impedance so as to produce a recording current thereby spreading a low cut-off frequency. CONSTITUTION:An effective input impedance Rin of a recording circuit RK viewed from a secondary winding of a rotary transformer RT shows a practi cally sufficiently low impedance because common-base amplifier circuits BE1, BE2 and negative feedback circuits NF1, NF2 are provided in an input circuit section.
