Title: A sodium-ammonium compound process for extracting lithium
Inventor: ARCHAMBAULT MAURICE
IPC: C22B26/12
Filed: 1962-01-10
Abstract: Lithium values are extracted from a calcined lithium-bearing silicate by contacting said silicate at 70-130 DEG  C. with an aqueous solution of sodium hydroxide, pyroborate, orthoborate, sulphide or silicate in an amount such that the amount of sodium compound used is from 1-3.5 times the amount theoretically required to react with the lithium oxide in the charge, water being present in an amount of of 1.5 to 10 times the weight of the lithium-bearing charge, thereby producing an aqueous slurry containing anisometric sodium zeolete and a newly-formed insoluble lithium silicate. When carried out at above 105 DEG  C. an autoclave is used.  The starting materials are calcined beta-spodumene, lepidolite, petalite and eucryhtete. The lithium silicate thus formed may be separated or treated in the slurry as above at - 10 DEG  to 40 DEG  C. with aqueous ammonium carbonate solution containing ammonium carbonate 3-25 times the weight of lithium oxide present.  The anisometric sodium zeolite is converted into ammonium zeolite and the lithium content forms a soluble lithium/ammonium carbonate complex.  The solid ammonium zeolite and silicic residue are separated and the lithium/ammonium complex solution which also contains sodium ions is heated to precipitate lithium carbonate and drive off ammonia and carbon dioxide gases. The sodium-containing solution after treatment may be returned to the first extraction process, and the by-products ammonia and carbon dioxide gas may be combined to form the ammonium carbonate solution used in the second process above.

Title: Remote supervisory unit
Inventor: SUZUKI AKIRA
IPC: G08B23/00
Filed: 1990-01-05
Abstract: PURPOSE:To surely catch phenomenon in a short period occurring sometimes by providing a gate circuit for switching to hold the final video when the abnormality signal of a process is supplied and to transmit the video to a centralized supervisory room as a still picture. CONSTITUTION:An image of constant cycle is fetched in a frame image memory 2c, and image transmission is performed via transmission equipment. A second frame image memory 2d always fetches the video, and the second frame image memory is fixed by stopping the fetch of data when certain abnormality occurs in the process. The video when the abnormality occurs is preserved by prohibiting the fetching of the image in the second frame image memory. The image preserved in the second frame image memory 2d is transmitted at the timing of the next cycle transmission instead of a normal transmission image in that cycle. In such a way, it is possible to surely monitor the phenomenon in a short period occurring sometimes.

Abstract: PURPOSE:To moderate a stress which acts on an optical semiconductor element and to prevent it from deteriorating in brightness by a method wherein the optical semiconductor element is pre-dipped into an epoxy resin compound which contains thio- phosphite and then sealed up with epoxy resin compound which contains no thiophosphite. CONSTITUTION:An optical semiconductor device formed in such a manner that an optical semiconductor element is connected and fixed to a metal lead frame is dipped into an epoxy resin composition I which contains epoxy resin phtalate anhydride and thiophosphite to form an epoxy resin composition layer on the surface of the device. The optical semiconductor device coated with the epoxy resin composition layer is sealed up with an epoxy resin composition II which contains epoxy resin and phtalate anhydride to form an optical semiconductor sealed device. The epoxy resin composition II which seals up the optical semiconductor device is prevented from coming into direct contact with the surface of the semiconductor device to seal up, so that stress acting on the optical semiconductor sealed device induced by the composition II can be moderated to be small. As the pre-dipping composition I is basically equal to the sealing composition II in composition, an optical interface is prevented from being formed between the compositions I and II, so that they are transparent.

Title: Mobile station control system for simple portable telephone system
Inventor: FUJITA EIJI
IPC: H04W56/00
Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To secure a smooth shift to an operation starting state from a stand-by state and to save the electric power of a mobile station by judging the propriety of a transmitting operation based on a fact whether the data received right before the starting are synchronous with the data received from a base station. SOLUTION: A clock control part 9 generates a control signal to switch the clocks used at a main counter part 7 based on a transmitting operation request, a receiving operation request, carrier sense operation request and the receiving result state. When a starting request is received for the transmitting operation or carrier sense operation in the stand-by state of a mobile station, these requested operations are carried out by means of a fast clock only when the receiving result is normal at the timing allocated to its own station and included in the data on a prescribed slot arrangement received from a base station and also when the synchronization is detected between the data transmitted from the base station and a frame.  At the same time, a receiving level measurement control part 11 performs the carrier sense operation based on the carrier sense operation request and the clock control information given from the part 9.
