Title: Fixture for light-emitting diode
Inventor: SUENAGA TSUYOSHI
IPC: H01L33/00
Filed: 1986-06-20
Abstract: PURPOSE:To prevent the inclined mounting of an LED, and to obviate breakdown by static electricity and damage by external force by installing a fixture constituted of a metal fixing an LED fitting fastened to a printed wiring board and electrically grounding the LED fixture. CONSTITUTION:An LED fixture 4 and an LED 3 are soldered in order to fix the LED 3 to a printed wiring board 2. A cathode lead for the LED 3 is connected electrically by the fixture 4 and the pattern of the wiring board 2 at that time, and grounded by leads 5 for grounding. Consequently, when the wiring board 2 is set up to a box body 1, inclined damage is removed and the state in which the diode 3 is fitted to the wiring board 2 is kept because the diode 3 is fastened by the fixture 4. The wiring board 2 is fixed to the box body 1 by a mounting screw 6. The LED 3 is not tilted nor damaged even at the time of repair. Even when static electricity is applied when the wiring board 2 to which the LEd 3 is fitted is set up to the box body 1 or after the wiring board 2 is mounted to the box body 1, the LED 3 is not broken because the LED 3 is grounded through the fixture 4. 2a: circular hole, 4: Light-emitting diode fixture, 3: Light-emitting diode, 1b: Guide pin, 1c: Hose, 1a: Square hole.

Title: Electronic device
Inventor: KARAUCHI ICHIROU
IPC: H01L31/10
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To mount a variable passive element on a resin-molded electronic device. SOLUTION: An electronic device is provided with a first resin-molded section 2 formed by sealing an electric circuit constituted of an active element and a passive element with a resin and a second resin-molded section 4 formed by sealing an optical element with a transparent resin. A variable passive element 12 is housed in a recessed section 10 integrally formed at the side edge section of the second resin-molded section 4 and electrically connected to the electric circuit. At a prescribed position of the recessed section 10, a regulating section 14 of a projection, etc., is provided at the position of an angle of rotation at which the electrical characteristic of the variable passive element 12 becomes discontinuous.  When the element 12 is adjusted by using a jig, the electrical characteristic of the element 12 can be prevented from becoming discontinuous, because the element 2 comes into contact with the regulating section 14 on this side of the angle of rotation at which the electrical characteristic of the element 12 becomes discontinuous.

Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To protect a tilting mechanism for an ice storage detecting body and an ice making means by stopping ice making and ice removing operation when a full state is detected by a detecting switch even momentarily. SOLUTION: When a water tray is inclined during ice removing operation, an ice storage completion detecting switch SW3 is brought into an ON state and a full storage state is detected, a relay X4 is energized, a normally-opened contact point X4-a1 coordinating with the relay is closed, and the relay X4 is self-held. A timer TM is started to count a preset set time. Further, a normally-opened contact point X4-a2 of the relay X4 is closed and energization to a relay X1 is brought into a practicable state. When the water tray is inclined to an inclination lower end, a switch SW2 for inclination effects ON operation, and the relay X1 is energized through the normally opened contact point X4-a2. This constitution releases the normally-opened contact points X4-b1 and X4-b2 coordinating with the relay X1 and stops the tilting of the water tray and ice making and ice removing operation.
