Title: Preparation of thermal head
Inventor: SAIDA KATSUAKI
IPC: B41J2/345
Filed: 1982-01-28
Abstract: PURPOSE:To obtain a thermal head without causing the variation of resistance value in response to the positioning accuracy of a mask by such an arrangement wherein the separation of resistors and the drilling of many holes on the resistors are carried out by using the same mask and photolithographic technique. CONSTITUTION:At first, on a substrate, a resistor layer and an electric conduction layer thereon are formed, and after that, small sections corresponding to the electric conduction layers 7 are removed by using a mask and photolithographic technique, and then beltlike sections corresponding to the electric conduction layers 8 are removed by using the mask. Next, by using the mask, the separation of resistors and the drilling of many holes in the resistors are simultaneously carried out by photolithographic technique. As the separation of resistors and the drilling of many holes in the resistors are performed by using the same mask, the sides L, M of the heat generating element in the direction of its electrode and gaps D3, D4 between sides and the holes 12 are constant in all thermal heads and there is no variation between lods and the yield of products is considerably raised.

Abstract: PROBLEM TO BE SOLVED: To provide a low capacity structure and provide a semiconductor laser having high-speed response property, by making the impurity concentration of the vicinity portion of its each junction interface in a structure approach zero asymptotically as approaching the junction interface. SOLUTION: After laminating an InGaAsP active layer 2 and n-InP clad layer 3 on a p-InP substrate 1, a mesa of about 1.5μm in its active layer width is grown by etching to bury in both the sides of the mesa p-InP first buried layers 4, n-InP first buried layers 5, p-InP second buried layers 6, and an n-InP second buried layer 7. Then, the impurity concentration distribution in each p-n junction region 8 is so varied across this region that the p-n impurity doping concentration is reduced from 2×10<-3> to undoped value. Thereby, the step of the energy band structure of the p-n junction region 8 is made moderate and the depletion layer thereof is also made wide. As a result, the capacity of the p-n junction is reduced.

Abstract: PURPOSE: To secure the continuous return test just through setting the original data by comparing the data drawn into the receiving register via the arithmetic circuit with the held corresponding transmitting data and carrying out the next division when a coincidence is obtained through the comparison.  
     CONSTITUTION: Division circuit 7 is started with application of the original data, and the division result is set to communication register 9 as the test data to be then sent to the communication system. Thus, the division is repeated via register 6 and 5. On the other hand, the data returned from the reception circuit is changed to the parallel row through parallel-series conversion register 12 to be drawn into receiving register 11. Here arithmetic circuit 8 compares the data drawn into register 11 with the corresponding receiving data to be held at register 5, and the next division is carried out at circuit 7 when a coincidence is obtained in the above comparison. In case no coincidence is obtained, the division is stopped, and the error is displayed via register 4. Thus, the continuous return test is possible for the communication system of various patterns just by setting the original data.

Title: Fused salt type fuel cell
Inventor: OKADA HIDEO
IPC: H01M8/02
Filed: 1982-01-29
Abstract: PURPOSE:To obtain a fuel cell where high performance can be maintained for long term, by previously holding more electrolyte than that required for reacting with an electrode material in a thin hole of an anode and/or cathode thereby preventing the flow-out and movement of the electrolyte from an electrolytic member to the electrode. CONSTITUTION:More electrolyte than that required for reacting with an electrode material is held in thin hole of an anode and/or cathode. When all holes are filled with the electrolyte, the dispersion of the reaction gas is slowed considerably thereby the three-phase interface is not formed easily to deteriorate the electrochemical reaction. In order to promote the electrochemical reaction, the holding amount is preferable to be more than that required for the electrode material while less than 50vol.% of the electrode thin hole volume. When it will exceed over 50vol.%, the gas diffusion is deteriorated to deteriorate the cell performance.
