Title: Semiconductor device
Inventor: SANO YOSHIAKI
IPC: H01L21/60
Filed: 1988-01-18
Abstract: PURPOSE:To prevent a wire from touching a wire chip fixing portion by a method wherein a short wire which does not hang down easily by nature pushes up a long wire which easily hangs down, to control the hanging amount of the long wire. CONSTITUTION:There is a semiconductor device in which a chip fixing portion 7 and a lead frame 8 are on the same plane, a semiconductor chip 2 having a plural number of pads to be connected via a wire to the same lead frame is fixed on a chip fixing portion 7, and respective pads are electrically connected to the same lead frame via different wires and sealed with resin. In this semiconductor device, wires are composed so that a long wire 11 crosses over a short wire 12. Therefore, the long wire 11 which easily hangs down is pushed up by the short wire 12 which does not easily hang down by nature to control the hanging amount of the long wire 11. This prevents an unnecessary contact of the load frame with the chip firing portion even if the lead frame is plane.

Title: Darlington connection type transistor circuit
Inventor: KARASAWA SHIZUO
IPC: H03K17/04
Filed: 1986-01-17
Abstract: PURPOSE:To shorten a turn-off time without extending a turn-on time by connecting a capacitor, a diode and a resistor between the base and emitter of the prestage transistor (TR) of a Darlington connection type TR. CONSTITUTION:The Darlington connection is constituted by connecting the emitter of the prestage TR1 to the base of the poststage TR 2. A serial circuit consisting of a resistor 9 and a capacitor 7 is connected between the base of the TRs 1, 2 and a diode 10 is connected to the base side of the TR1 as a cathode in parallel with the resistor 9.

Title: Start up circuit for linking photovoltaic power generating inverter
Inventor: SHIRAISHI TOMOO
IPC: G05F1/67
Filed: 1987-01-13
Abstract: PURPOSE:To improve the utilization factor of sunlight in spite of fluctuation in temperature, by compensating a voltage at the time of starting up according to the temperature of a solar battery, in a power generating system in which an inverter is started up when the no-load voltage of the solar battery reaches at a value larger than a prescribed value. CONSTITUTION:A temperature is detected by a temperature detector 5 arranged adjacently to the solar battery 1. A detected value is converted to a voltage value, and is sent to a start up circuit 3, and a voltage V0, is set by correcting a reference voltage V0 at the time of starting up in which an open voltage regulated according to a quantity of solar radiation under a constant temperature is set as reference, by a differential amplifier 7. A corrected voltage V0, is compared with the open voltage Vx of the solar battery 1 at a comparator 8, and when the latter is larger than the former, an inverter part 2 is started up by a control circuit 4. Under the temperature where the reference voltage V0 is set, a correction quantity is zero, and since the open voltage of the solar battery 1 increases under the temperature less than that, the reference voltage is corrected to a plus side, and it is corrected to a minus side under the temperature exceeding that.
