Filed: 1989-08-10
Abstract: PURPOSE:To protect a semiconductor device against sputtering damage so as to improve it in breakdown voltage property by a method wherein a first electrode is formed of silicon containing aluminum, silicon, and a second electrode is thicker than the first one and formed of aluminum which substantially contains no adventitious silicon. CONSTITUTION:A first electrode 36 of a Schottky diode is formed of silicon- containing aluminum, and a second electrode 39 is thicker than the first electrode 36 and formed of aluminum which substantially contains no adventitious silicon. Therefore, silicon contained in the first electrode 36 is absorbed by the second electrode 39, so that alloy spikes are apt to occur in a Schottky barrier diode 28 forming region. Therefore, as the first electrode 36 is located at a contact hole 34 of the Schottky diode 28, an epitaxial layer 22 located in this region is free from sputtering when aluminum oxide is argon-sputtered. By this setup, a Schottky barrier diode of this design is prevented from deteriorating in breakdown voltage due to sputtering damage.

Title: Electric instantaneous water heater
Inventor: TAKAI MITSUO
IPC: F24H1/00
Filed: 1985-09-20
Abstract: PURPOSE:To promptly stop the power supply to a heater at an extraordinary time and prevent a dangerous condition from occurring by fitting the temperature sensing part of a temperature excess rise preventing device to the upper surface on a core of a water inlet pipe. CONSTITUTION:When a valve 13 is opened at the time of normal use, a pressure switch 14 is turned ON in linkage therewith, and a sheathed heater 9 is in a power supplied state. Water flowing into a tank 1 through a water inlet pipe 11 is throttled at a water inlet port 11a, and accelerated. Then, water passes through a spatial portion 8a, and reaches the upper part of a tank 8, hitting the inner wall of a tank upper surface 8b below a temperature sensing part 12a of a thermostat 12 and is reversed and diffused. At this time, while being heated by the sheathed heater 9, water flows toward the lower part of the tank 8, and passes the inside of a hot water supply pipe 10 and is supplied for use. Accordingly, the temperature sensing part 12a is constantly cooled by inlet water at the normal time. On the other hand, at an extraordinary time where inlet water is stopped as it is and the heater 9 is still in the power supplied state, it is rapidly heated by a heat convection within the tank because the temperature sensing part 12a undergoes no cooling effect due to inlet water and is located on the upper surface of the tank. At the extraordinary time, power supply to the heater is promptly stopped, and a dangerous state is prevented from occurring.

Title: Position detector
Inventor: MASUDA SUMIO
IPC: G01D5/48
Filed: 1992-08-06
Abstract: PURPOSE:To obtain a sufficient detection signal level by non-touch method and obtain a simple structured position detector by detecting the scattered pulse from a scattering source where magnetic elastic wave transmitting in a non-crystal magnetic body cancels a bias magnetic field resulting in reduction at the part. CONSTITUTION:Many steps are formed on the surface of a non-crystal magnetic line 1 by etching, where magnetic elastic wave is scattered to form scattered wave propagating to the reverse direction to the incident wave. As the magnetic line 1 has magnetic distortion, magnetic elastic wave is driven by impressing pulse magnetic field with a coil 4. The magnetic elastic wave having reached the vicinity of the coil 4 is detected by the coil 4 with the reverse effect of the magnetic distortion. When the magnetic field by a bias coil 9 is locally canceled by a magnet 10, the magnetic elastic wave suddenly decreases there. Therefore, the pulse scattered due to further steps from the coil 4 than the magnet 10 position decreases and the amplitude reduces. Thus, by counting the pulse with large amplitude, the magnet 10 position is detected.
