Patent JP-H05226594-A (JP)
Title: Semiconductor device and manufacture thereof
Inventor: KITAMURA YOSHIHIRO
IPC: H01L27/088
Filed: 1992-02-15
Abstract: PURPOSE:To prevent that the breakdown strength between diffusion layers to be used as sources and drains for adjacent LDD-structure transistors is deteriorated even when an element isolation region is made small in the LDD-structure MOS transistors wherein the element isolation region, low-concentration diffusion-layer regions and high-concentration diffusion-layer regions are provided. CONSTITUTION:A CMOS LSI is constituted of the following: an element isolation region which is formed of a channel stop region 6 and of a field oxide film 8; low-concentration n-type diffusion layers (n<-> diffusion layers 13); and high- concentration n-type diffusion layers (n<+> diffusion layers 16). The CMOS LSI is formed in such a way that the element isolation region and the low- concentration n-type diffusion layers (the N<-> diffusion layers 13) exist without coming into contact with each other. Even when an element isolation width is reduced by a selective oxidation operation, the breakdown strength between the diffusion layers can be ensured because the distance between the low- concentration diffusion layers to be used as sources and drains for adjacent LDD-strucutre transistors is separated sufficiently.

Title: Power supply circuit for audio output circuit of television receiver
Inventor: SHIMOYANAGIDA SUSUMU
IPC: H01F19/04
Filed: 1991-03-26
Abstract: PURPOSE:To obtain a high audio output inexpensively and to suppress the disturbance onto a screen attended with fluctuation of an audio output by using a voltage obtained from a rectifier circuit for a power supply for an audio output circuit. CONSTITUTION:A re-trace rectifier circuit 24 comprising a resistor 21, a diode 22 and a capacitor 23 is connected to a heater terminal 5. In this case, since an internal impedance of a heater winding is small and a voltage change of nearly 0.1Vrms is caused, the effect onto a heater 12 due to a current change is not almost caused. Even when a transient voltage fluctuation more or less takes place depending on the specification of the winding, since the heater 12 of a CRT (cathode ray tube) has a large thermal capacitance, no effect is caused onto a picture on to a TV screen.
