Title: Antenna multicoupler
Inventor: NAKAMURA TOSHIAKI
IPC: H01P1/213
Filed: 1988-02-04
Abstract: PURPOSE:To attain a small sized antenna multicoupler and high performance by dividing a reception band and a transmission band into high and low bands respectively and switching a notch filter in response to a desired pass band. CONSTITUTION:Transmission/reception notch filters 17, 18 are connected to transmission/reception terminals 11, 12 via a switch 16. The transmission/ reception band is divided respectively into high and low bands, and when a signal passes through a low transmission band, the switch 16 connects the filter 17 to increase the attenuation at the high frequency band of the transmission filter 14. On the other hand, when the signal passes through a high transmission band, the switch 16 connects the filter 18 to increase the attenuation at the low frequency band of the transmission filter 15. Thus, the notch filters 17, 18 are switched to increase the attenuation of the isolation point of the transmission reception largely from the side band and the small sized and high performance multicoupler having a wide pass band is obtained.

Title: Field-effect transistor and its manufacture
Inventor: OKUDA YASUSHI
IPC: H01L21/336
Filed: 1989-02-02
Abstract: PURPOSE:To contrive the improvement of the operating speed of a FET and the inhibition of deterioration of the characteristics of the FET by a method wherein parts of an element isolation region formed in a semiconductor substrate are removed and poly silicon is buried in the removed parts to form the source and drain electrodes of the FET. CONSTITUTION:Parts of an element isolation region 2 formed in a P-type semiconductor substrate 1 are removed and polycrystalline silicon buried electrode parts 5 are formed at the removed parts. Moreover, an N-type impurity, such as arsenic, phosphorus or the like, in the parts 5 is diffused in the substrate 1 by a heat treatment to form N-type semiconductor layers 4. In a FET formed in such a way, as the are of the junction parts between the layers 4 and the substrate 1 are small, the capacitances of source and drain regions become small and the operating speed of the FET is improved. Moreover, as the field intensity in the vicinity of the drain region at the time of operation of the transistor is relaxed, the deterioration of the characteristics of the transistor, which is caused by the effect of hot carriers, can be inhibited.

Title: Electric hot water heater
Inventor: TOMOTA SHINICHI
IPC: F24H1/18
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for the use of electricity in the daily time zone where the electric charge is higher than necessary while preventing the shortage of hot water by automatically setting extra boiling when an electric water heater itself is under a power system that allows extra boiling for the daily time use. SOLUTION: When an extra boiling is made, as the electric charge is comparatively dear, a user tries to set an extra boiling by himself using a remote control or the like, which often leads to the inadvertent neglecting of the setting, eventually causing a failure of the shortage of hot water with the omission of the extra boiling in the daily time. There are arranged a power source supply detection means 21 which detects to determine whether the supply of a power source exists or not at an fixed time interval, a time counting means 22 and a power system judging means 23 which counts the frequency of the existence of the supply of the power source as detected by the power source supply detection means 21 while the time counting means performs a counting of time for 24 hour to judge the power system from the numerical value obtained.  When the power system judging means 23 determines the power system to allow the daily time extra boiling, an upper extra boiling using an upper heating body 3 alone is automatically set.
