Title: Initial resetting circuit
Inventor: ARASE KENSHIROU
IPC: H03K17/22
Filed: 1980-07-17
Abstract: PURPOSE:To make an external capacitor for forming a reset signal unnecessary, by utilizing an internal boosting circuit and forming a reset signal in case when an electric power supply is turned on, in an MOS type integrated circuit incorporating a boosting circuit of supply voltage. CONSTITUTION:A supply voltage VDD-VSS1 system is boosted by two times to a VDD-VSS2 system through a boosting circuit 8. In this case, when an electric power supply is turned on, a time is required to some extent before boosted voltage develops in the VDD-VSS2 system, and during this period, an n channel MOSFET2 is off. On the other hand, a p channel MOSFET1 turns on as soon as the electric power supply is turned on, and a reset signal of a low level appears in a terminal 7. When boosted voltage develops in the VDD-VSS2 system, MOSFETs 1, 2 both turn on, and when an on-resistance of the MOSFET1 is made larger than an on-resistance of the MOSFET2, a voltage level of the terminal 7 becomes a high level.

Title: Semiconductor device sealed with resin
Inventor: TAKAHASHI ATSUSHI
IPC: H01L23/28
Filed: 1990-04-13
Abstract: PURPOSE:To prevent the generation of warp in a semiconductor and crack in sealing resin by exposing the tips of a plurality of pieces of hanging pins at the mounting part to the outside of sealing resin, besides making the shape of the semiconductor chip mounting part into mesh shape so as to make the contact area smaller than the bottom of the semiconductor chip. CONSTITUTION:A semiconductor chip 1 is placed on the semiconductor chip mounting part 2 in mesh-shaped being supported from the periphery by plural pieces of hanging pins 3, and is bonded by solder material 7. The flexural strength when the semiconductor chip mounting part 2 takes such a shape weakens, and remarkably suppresses the generation of the internal stress of the semiconductor chip 1 in soldering. Moreover, the chip counting part 2 is connected to a plurality of pieces of hanging pins 3 whose tips are exposed to outside, so even if steam is generated from inside in actual mounting to a printed board, it can be released to outside from the periphery of sealing resin 6, whereby the generation of cracks in resin can be prevented effectively.

Abstract: PURPOSE:To determine the output frequency of a VCO only with a power source voltage, a frequency control voltage, and a time constant by providing an analog switch circuit between the output of an operational amplifier and the in-phase input of the operational amplifier. CONSTITUTION:An analog switching circuit 2 is provided between an output (a) of an operational amplifier 1 and an in-phase input (b) of the operational amplifier 1.

When it is turned off, a bias V0 due to a bias generating circuit 3 is applied to the in-phase input (b). When a positive power source voltage VC is applied to a gate input (g) of the switching circuit 2, the circuit 2 is turned on, and the signal Vi applied to a terminal (e) is led out to a terminal (f). When a negative power source voltage VE is applied to the gate input (g), it is turned off. Thus, the output frequency of the VCO is determined only by the power source voltage, the frequency control voltage, and the time constant.

Abstract: PROBLEM TO BE SOLVED: To enable restraining unwanted electromagnetic waves, by enabling selective connection of a dumping circuit, a filter circuit, etc., and a bypass circuit between a power source layer and a ground layer of a printed board, with a siring part transmitting a high frequency signal. SOLUTION: A wiring from a clock generator circuit 404 mounted on a printed board to a CPU 405 is applied also to a path transmitting signals of CL2-CLn besides a signal wiring path of a clock signal CL1. An MOS type transistor TR1 is an N-channel type, R1 is resistance between a drain D and a source S, an MOS type transistor TR2 is also an N-channel type, and R2 is used as resistance between a drain D and a source S. When high level signals are inputted to the respective gates G, the source and the drain are electrically connected, and the resistance between the source and the drain acts as function of a dumping resistance. Since suppression circuits having different constants can be selected, a re-suppression circuit coping with change of specification of components to be mounted on the printed board and change of mounting arrangement is made unnecessary.
