Title: Reservoir type water heater
Inventor: YAMAZAKI TADASHI
IPC: F24H9/20
Filed: 1984-10-15
Abstract: PURPOSE:To average out the power load and also to improve the power transmission efficiency by computing the calorific value to be inputted from the amount of remaining hot water and ground temperature so as to control the power to a heat generator by determining the required power consumption by the heat generator based on the afore-said computation result. CONSTITUTION:Hot water contained in a reservoir tank 11 is designated to be U liter at T1 deg.C, which is inputted to a hot water amount setting means 19. The ground temperature is designated to be t deg.C, which is also inputted to the hot water amount setting means 19. An arithmetic means 21 computes the heating completion temperature T3 deg.C by UXT1=VXT3+t(U-V), where V is the capacity in liter of the reservoir tank 11. Where T2 deg.C is the average temperature 22 after mixing the remaining water in the upper part of the reservoir tank 11 with the feed water in its lower part, an arithmetic means 23 computes the required power W by (T3-T2)V=etaX860XWXH, where eta is the heating efficiency of the heater generator, and H is the night-time electrification time to be operated by means of a timer. The power is controlled by a control device 24, and the electrification is carried out during the night-time power transmission time by the timer.

Title: Semiconductor laser device
Inventor: GOTO YUKIO
IPC: H01L21/205
Filed: 1987-08-28
Abstract: PURPOSE:To reduce a reactive current, and to perform a low threshold value and a low current operation by forming an active layer, a semiconductor layer between a current block layer and the active layer to generate an ordering effect, and eliminating the ordering effect in the semiconductor layers to form an impurity diffused region for specifying a current path. CONSTITUTION:A clad layer 2, an active layer 3 and a clad layer 4 are sequentially formed on a substrate 1. Growing conditions for generating an ordering effect are suitable, for example, in ranges of 600-700 deg.C of growing temperature and 200-300 of group V/III material ratio. After a stripelike groove 7 is formed, Zn in a current block layer 5 is diffused in the layers 4, 3, 2 to form diffused regions 4a, 3a, 2a. The ordering effects are eliminated in the region 4b in the layer 4 in which the impurity is diffused, the region 3b in the layer 3, and the region 2b in the layer 2, band gap energies are enhanced as compared with nondiffused regions 4a, 3a, 3a in which the impurity is not diffused, and an energy barrier for specifying a current path is formed between both the regions.

Title: Electrode material for fuel cell of molten carbonate type
Inventor: ISHIBE HIDEOMI
IPC: H01M4/86
Filed: 1985-09-28
Abstract: PURPOSE:To provide a fuel cell electrode material which has a greatly enhance strength and long life and does not undergo cracks or the like under the influence of heat, by making a nickel powder with short nickel fibers. CONSTITUTION:A nickel powder 1 and short nickel fibers 2 of 20-30mum in diameter and 2-20 in aspect ratio (L/D) each are mixed with each other and sintered together to constitute a fuel cell electrode material. Although the diameter of each grain of the nickel powder 1 is selected in terms of the properties (pore diameter and porosity ratio) of the electrode material, it is preferable that the diameter is 0.5-50mum. If the diameter of each of the short fibers 2 were less than 2mum, an electrolyte would not sufficiently enter into the material and the reinforcement thereof would not be enough. If the aspect ratio were less than 2, the nickel fibers 2 would become almost powdery to make it difficult to attain a porosity ratio required for the electrode material and would not perform a reinforcing function. If the aspect ratio were more than 20, it would be difficult to uniformly disperse the nickel fibers 2 and it would be likely to make the strength of the electrode material nonuniform.

Abstract: PURPOSE:To prevent increase of gate-source or gate-drain capacitance and to prevent deterioration in high-frequency characteristics, by providing a gate electrode which is in contact with a channel region in an area smaller than the size of the gate electrode. CONSTITUTION:An N-type channel region 5 in a semiconductor substrate 7 on which a gate electrode 2 is carried has a surface 5a to be in contact with the gate electrode 2 and the surface 5a has a length or effective gate length Lg2 that is smaller than an actual length Lg3 of the gate electrode 2. In other words, shoulders 5b and 5c of the N-type channel region 5 are inclined such that they reach down to an N<+> type source region 4 and an N<+> type drain region 6, respectively. Thereby, the N<+> type source and drain regions 4 and 6 are electrically isolated from the gate electrode 2. In this manner, the distance Lsd between the source and the drain can be shorter than the effective length Lg of the gate electrode without need of using any dielectric for isolating the N<+> type source and drain regions from the gate electrode 2 and without involving increase of gate-source capacitance Cgs and source-drain capacitance Cgd.
