Filed: 1979-01-26
Abstract: PURPOSE:To reduce the number of power supply terminals of a monolithic semiconductor integrated circuit, by making use of a voltage, supplied via the IF coil of a ratio detector, as the power supply of an emitter-follower AM detection circuit. CONSTITUTION:With FM-AM aldternation switch SW placed at the FM side, the supply of power to AM high-frequency circuit 4 and AM intermediate-frequency amplifier circuit 5 is cut off, and consequently Darlington transistors Q3 and Q4 constituting an emitter-follower AM detection circuit turn OFF, so that no influence upon FM reception will be exerted. With switch SW at the AM side, on the other hand, the supply of power to FM intermediate-frequency amplifier circuit 2 is cut off and while output transistor Q2 turns OFF, the coil of FM ratio detection circuit 3 and a capacitor circuit become low in impedance to an AM intermediate frequency signal, so that the voltage at external pin P2 will be utilized as the power supply of the emitter-follower detection AM circuit.

Title: Repairing method of semiconductor device
Inventor: HANABUSA YOSHIAKI
IPC: H01L21/60
Filed: 1985-01-21
Abstract: PURPOSE:To join a new semiconductor chip to a mounting substrate properly, by leaving protuberant electrodes in a prescribed amount or little respectively on the mounting substrate side when a preceding semiconductor chip is removed from the mounting substrate, and by utilizing a plane left behind. CONSTITUTION:A semiconductor device is mounted on a mounting stage 4 with the mounting substrate 3 thereof down, and position-adjustment is conducted so that the part of a semiconductor chip 1 comes to the central part of the mounting stage 4. Next, the semiconductor chip 1 is sucked and held by a vacuum holding jig 6 and is heated from the mounting substrate 3 side by infrared rays 5 while subjected to minute vibrations in the horizontal direction by a vibrator. When the material of protuberant electrodes 2 begins melting, the chip is exfoliated from the mounting substrate 3. On the occasion, the vacuum holding jig 6 is moved upward to separate the semiconductor chip from the substrate. According to this method, the material of the protuberant electrodes 2, such as a solder bump, is scarcely left behind in a part wherefrom the semiconductor chip 1 is removed. Therefore a mounting plane is made flat, and thus a new good semiconductor chip can be joined thereon properly.

Title: Device for coping with abnormality of lock-up torque converter
Inventor: MURASUGI TAKU
IPC: B60W10/10
Filed: 1988-01-19
Abstract: PURPOSE:To prevent the deterioration of working fluid and the fusing failure of parts which are readily affected by heat by providing a lock-up means which is responsive to signals from a coupling condition detecting means and a stator rotation detecting means and which carries out direct connection when a stator fails to rotate in spite of a coupling condition. CONSTITUTION:During the detection of a coupling condition, the input/output elements of a lock-up torque converter are rotated being accompanied by a stator in the same direction. In this case, if a one-way clutch for supporting the stator is locked because of abnormality, the stator fails to rotate accompanying the input/output elements even in a coupling condition, causing the torque ratio and efficiency of the torque converter to be lowered in the coupling condition. In this case, however, since a lock-up means directly connects the input/ output elements of the torque converter, the lowering of the torque ratio and efficiency can be prevented. Hence, the stepping-in of an accelerator pedal may be as usual, preventing the unusual rise in working fluid temperature and accompanying deterioration of the working fluid as well as the fusing failure of parts which are readily affected by heat.

Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To shorten the processing delay time of a large capacity time switch (TSW) circuit by removing a delay at the time of cascade-connecting switch circuits each of which is combined by a TSW circuit and a space switch(SSW) circuit. SOLUTION: In the large capacity TSW circuit, addresses to be read out from read-only memories (ROMs) constituting time setting circuits 12 on respective stages are set up as follows. Namely the final stage is set up as a 1st stage, an address '0' is set up in the ROM constituting the time setting circuit 12 on the final stage, an address '1' is set up in the ROM constituting the time setting circuit 12 on the 2nd stage from the final stage and an address 'i-1' is set up in the ROM constituting the time setting circuit 12 on the i-th stage from the final stage. Thereby the phases of data read out from all the TSW circuits coincide with that of data read out by a final stage TSW circuit 1-2 at the time of inputting the data to a final stage SSW circuit 2-2.  Consequently the input of the final stage SSW circuit 2-2 is allowed to coincide with the frame phase of the final TSW circuit 1-2.
