Abstract: PURPOSE:To prevent any leakage current from occurring by a method wherein a base as the first impurity diffused layer is formed in an epitaxial layer to be a collector to form the second impurity diffused layer as an emitter in junction depth deeper than that of the first impurity diffused layer inside the base. CONSTITUTION:A base B as the first P type impurity diffused layer in shallow junction depth is formed almost in the central position of an element region of an epitaxial layer 11 while inside the base B, the second impurity diffused layer to be an N<+>type emitter E in junction depth deeper than that of base B is formed so that the emitter E protruding from the base B may be in direct contact with the epitaxial layer 11 working as a collector. Thus, the emitter E and the epitaxial layer 11 are impressed with the same potential so that when the emitter E is impressed with high potential, the epitaxial layer 11 may be impressed with the same high potential to impress the base B and the epitaxial layer 11 with inverse bias. Through these procedures, any leakage current can be prevented from occurring without forming any parasitic transistor at all.

Title: Returning method for ice making tray
Inventor: YOSHIKAWA SHINICHI
IPC: F25C1/24
Filed: 1993-03-26
Abstract: PURPOSE:To prevent a shortening of the life of a motor attributed to operating condition by eliminating longer continuation of failure thereof in rotation while being energized, namely, a lock state in the process of reversing the motor to return an ice making tray. CONSTITUTION:After the generation of an ice detection signal when filling with ice occurs or the generation of an ice separation signal in the ice separating operation, a motor 15 is kept rotating in the direction of reversion thereof, namely, in the direction of returning an ice making tray 2 without being controlled hourly.

Abstract: PURPOSE: To prevent a human body from being damaged by the fall of a thunder- bolt, if any, by forming an electrically large gap in the course of transmitting the signals of a sensor so that a bath may be electrically isolated while optically transmitting and receiving the signals.  
     CONSTITUTION: A sensor 2 in a bath 1 is electrically connected through a coupling box 3 with a bath warning panel 4. If the water level and temperature of the bath exceed preset values, a contact 5 is closed to light an LED 6. Upon reception of this light, a phototransistor 8 becomes conductive to connect the relay circuit of the warning panel 4, i.e., a relay 9, a bridge rectifier 14, the phototransistor 8 and the relay circuit 9 so that this relay 9 is operated. In response to the operation of this relay 9, a contact 10 is closed to operate a warning lamp 12 and a buzzer 13. In case a thunderbolt falls at the service wire of a transformer 11 when a man takes bath with the sensor 2 being dipped in the bath, his body can be prevented from any damage because there is a sufficient cap formed between the transistor 8 and the LED 6.
