Title: Frequency converter
Inventor: TSUKUNI MITSUTAKA
IPC: H03D7/16
Filed: 1986-04-11
Abstract: PURPOSE:To prevent a signal before conversion from affecting a converted signal as an unnecessary wave by connecting two stages of frequency converter elements each composed of a frequency converter, a band-pass filter, and an oscillator in series and making their shift frequency different from each other. CONSTITUTION:A signal of transmission frequency fTX is converted to fSH1(=fTX- fLO1) by a frequency conversion circuit 1a with a signal of shift frequency fLO1. Then, the signal is passed through a band-pass filter 1b to remove unnecessary signals of frequencies fTX and fLO1. Then, a signal of frequency fSHT is converted to fRX(=fSHT-fLO2) by a frequency conversion circuit 1d with a signal of shift frequency fLO2 and then passed through a band-pass filter 1e to remove unnecessary signals of frequencies fSHT and fLO2 Consequently, the transmission frequency fTX is converted to a reception frequency fLO2. Therefore, even when the transmission frequency fTx and reception frequency fRX are extremely close to each other and a signal with a band is frequency-converted, the conversion is performed so that the transmitted signal affects the reception signal as an unnecessary wave.

Abstract: PURPOSE:To detect any wire bonding slip by electrical measurement by a method wherein detecting wirings are made on the surface of protective film around the periphery of openings and then the wirings are connected to probing pads independently formed on the surface of protective film. CONSTITUTION:Wirings 6, 7 encircling an opening are commonly connected by connecting lines 12, 13 encircling the other openings of a bonding pad 3. The wirings 6, 7 reach two probing pads 10, 11 exposing to the surface of element. Any wire bond slip can be detected by means of bringing probes 15, 16 into contact with the probing pads 10, 11 for checking conduction of the wire bonding. In other words, if all wire bondings are acceptable, there must be no conduction at all, however if there is any wire bonding slip, the end of contact bonding part will shortcircuit two wirings 6, 7 around the periphery of an opening to make the wirings conductive thus detecting that the wire bonding is defective.

Title: Fuel control device of internal-combustion engine
Inventor: YOSHINAGA TOORU
IPC: F02M41/12
Filed: 1983-05-16
Abstract: PURPOSE:To secure the safety as well as provide sure operation by connecting No.2 oil pressure chamber to No.1 relief port when the solenoid happens to be out of function. CONSTITUTION:A control circuit 18 stops the power supply to a solenoid 811 to allow a spring 813 to move a drive rod 812 leftward on the attached illustration wherein the tip thrusts a valve element 812c to cause opening of the valve, and now No.1 oil pressure chamber 824 opens to a ring-shaped relief passage through a gap between said drive rod 812 and the valve body 821h. Accordingly the pressure in No.1 oil pressure chamber 824 will sink. This pressure drop enlarges the pressure difference between this and another oil pressure chamber 825 to permits a spool 822 to displace against a spring 823 rightward in the attached illustration, and consequently a pressure chamber 131 is in communication with No.2 relief port 821b to sink the pressure in the pressure chamber 131. Thus fuel injection from the injection nozzle 2 is stopped.
