Title: Hot water reserving type electric water heater
Inventor: KUBOTA HIDEJI
IPC: F24H1/18
Filed: 1982-01-28
Abstract: PURPOSE:To prevent a water quantity from heating up more than it is required, by a method  wherein a necessary electrification time is reckoned to a hot water quantity preset for the following day's use by referring a detected value of a calorific value for residual hot water in a hot water reservoir, and electrification is started so as to enable to consume the above electrification time at a completion of a midnight electrification. CONSTITUTION:A hot water quantity for the following day's use is applied to a hot water  quantity setting device 5, correction temperatures, such as a fixed temperature for supply water immediately after an inrush into an electrification time and the lowest annual water temperature for various places is set beforehand and a calorific value K1 which is to be stored within  a hot water reservoir by a completion time of the electrification time is calculated by an arithmetic unit A 6. A necessary electrification time is calculated by an arithmetic unit B 8  through a net calorific value to be applied, which is obtained by deducting a calorific value corresponding to residual hot water based on a calorific value K1 calculated by the arithmetic  unit A 6 and a calorific value K2 for the residual hot water detected by a calorific value detecting device 7 for the residual hot water. Electrification to a heating unit 10 is started by a  timer 9 from the midway of a midnight electrification time by a timer 9 so that the necessary  electrification time calculated by the above arithmetic unit B 8 is obtained at a completion  time of midnight electrification.

Filed: 1984-01-27
Abstract: PURPOSE:To obtain a distance measurement output without reference to levels of both outputs of photodetecting element circuit systems and widen a usable range by deciding the output state of one photodetecting element circuit system when the output of the other photodetecting element system attains to a certain set value. CONSTITUTION:A distance measuring circuit consists of a clock pulse generating circuit 1, time generating circuit 2, infrared-light emitting diode 5, silicon photodiodes 6 and 7, photodetecting element output converting circuits 8 and 9, field- effect transistors 10 and 11, comparator circuits (CMP)17, 18, 35, and 36, potentiometers 38 and 41, etc. Then when output voltages Vb and Vb' at output terminals (b) and (b') of photodetecting element converting circuits 8 and 9 rise and the output voltage Vb reaches a reference voltage Vr, the output voltage Vb' is stored and supplied to one input terminal of the comparator 35; when potentials at both input terminals coincide with each other, a photographic lens is fixed at a specific position. Consequently, the distance measurement output is obtained without reference to the levels of both outputs and the apparent dynamic range is widened.

IPC: H01L21/316
Filed: 1990-01-25
Abstract: PURPOSE:To form a passivation film without depending on a warp state or the like of a silicon substrate and stably by a method wherein, after a lower- layer insulating film has been formed under the formation condition of a specific high vacuum, an upper-layer insulating film is formed under the formation condition of a specific low vacuum. CONSTITUTION:An electrode interconnection 12 is patterned on a substratum insulating film 13 on the surface of a semiconductor substrate 10. In this state, a plasma nitride film is formed under a high vacuum of 1.5Torr or lower. Since the plasma nitride film is formed under the high vacuum, a plasma discharge is stable and an abnormal discharge and a partial blistery foreign body are not caused. Then, a plasma oxide film is formed and completed under a low vacuum of 2.5Torr or higher. At the plasma nitride film 11 formed under the low vacuum, a plasma discharge shows a tendency to become unstable, but a stress is low. Since a semiconductor device is covered with the insulating film, the abnormal discharge and the partial blistery foreign body are not caused.
