Filed: 1981-02-18
Abstract: PURPOSE:To make a locus on a recording paper identical to that of an XY recording meter by shifting the recording paper longitudinally according to an X input produced with a construction of switching one of multiple pen inputs. CONSTITUTION:When switching devices 21 and 26 are turned to the position b separately, a pen 8 is lifted from a recording paper 16 and stops running while a signal of input IN2 is applied to one input of a comparator circuit 22. Receiving a clock, an U/D counter 23 starts counting and the contents of the counting are provided to the other input of the comparator circuit 22. On the other hand, the clock signal from the position b of the switching device 26 is branched off and provided to the input of a control circuit 13. Consequently, a driving circuit 14 outputs a driving pulse to drive a paper driving motor 15. A pulse is transmitted to a motor 15 to change the mode of rotation thereof from normal to opposite and vice varsa, as specified by a drive direction controlling circuit 24. Thus, according to the signal of input IM2, the position of the recording paper 16 shifts thereby constituting a locus of an XY recording meter having the input IN2 on the X axis and the input IN1 on the Y axis in the locus of the pen 7.

Filed: 1985-02-08
Abstract: PURPOSE:To eliminate the problem of oozing, and at the same time to improve the adhesion with resin, by removing the portion of plating metal other than those applied to a semiconductor element fixing section and inner lead terminal section. CONSTITUTION:The surface of a 42 alloy semiconductor lead frame base 1 formed by punching into a required pattern through press is partly plated within a resin-sealing region 2 by masking method. Next, only the semiconductor element fixing section 4 and the inner lead terminal section 5 in said region 2 Ag-plated 3 are masked, and the whole lead frame base 1 is dipped in an etchant. Then, the portion of Ag plating other than those of the sections 4 and 5 is removed, resulting in the production of a semiconductor lead frame 7 in the state 6 of coarsening the surface. This process can increase the contact area in adhesion with resin and the resin sealing distance; therefore, the moisture resistance can be improved.

Title: Space diversity receiver
Inventor: YOSHIKAWA TATSUO
IPC: H04B7/08
Filed: 1988-02-05
Abstract: PURPOSE:To cut off a second antenna system, to simplify a circuit and to reduce, cost by making an existing amplifier or a frequency converter a non-action condition when trouble is generated to a control part controlling the phase of a local oscillator. CONSTITUTION:When trouble occurs in a control part 12b and the phase control of a local oscillating signal by a phase shifter 7 is not executed normally, a switch circuit 15 is switched to a non-connection terminal side. As the result, the supply of a bias voltage to an amplifier 8 is stopped, and the amplifier 8 becomes a non-action condition. At the same time, a zero control signal is sent to the phase shifter, and a local oscillating level from the phase shifter 7 is attenuated. Thus, an antenna 2 system is made equivalent to a cut-off condition, and the improper synthesizing of antennas 1 and 2 systems is evaded. Consequently, the circuit can be constituted simply and at a low cost.
