Title: Gain controller
Inventor: YAMADA SHIGERU
IPC: H04B7/15
Filed: 1986-12-19
Abstract: PURPOSE:To make a gain to the respective temperature of a transmitter constant in the range of the quantizing error of an analog digital converter and the resolution of digital analog converter by providing the analog/digital converter, a read only memory and the digital/analog converter. CONSTITUTION:A temperature detector 51 outputs a constant voltage value to an ambient temperature and a microcomputer 57 reads this voltage value as a digital value through the analog/digital converter 54. Based on this value, the microcomputer 57 reads control data from the read only memory 55 to transfer to the digital/analog converter 56 and the digital/analog converter 56 drives a variable gain amplifier 50. Such an operation is carried out and temperature characteristic correction data to the output values of the temperature detector 51 in the respective temperature is stored in the read only memory 55. Thereby, the transmitter with a high accuracy in the stability in the gain to the temperature can be constituted.

Title: Production of single crystal
Inventor: OKAMOTO TSUTOMU
IPC: C30B15/00
Filed: 1993-12-03
Abstract: PURPOSE:To prevent cracking from being caused in the single crystal by cooling the singles crystal after the completion of its pulling up while allowing the singles crystal to keep in contact with the melt at the time of growing the low temp. phase beta-BaB2O4 singles crystal from the melt which has composition represented by the formula BaB2O4 and contains no flux. CONSTITUTION:The low temp. phase beta-BaB2O4 single crystal is grown from the melt while has composition represented by the formula BaB2O4 and contains no flux by using the pulling up method and after the completion of this pulling up, the single crystal is cooled while allowing it to keep in contact with the melt to produce the objective single crystal. Thus, since heat is transferred from the melt to the whole crystal through the bottom of the crystal by the heat conduction even when a steep temp. gradient exists just above the melt, the temp. difference within the crystal are small and the cracking due to the thermal shock are not caused. Also, the cooling rate of the crystal after growing it can be increased and therefore the working efficiency can be enhanced. Further, since the cracking is prevented from being caused, the whole crystal can be effectively utilized and the yield of the single crystal can be improved.

Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To prevent a reproduction signal from being interrupted even when more data than a prescribed amount are received with a time delay when the data sent via the Internet are temporarily stored by the prescribed amount and reproduced. SOLUTION: This equipment is provided with a buffer 907 that temporarily stores transmitted data, a storage section 921 that stores a data amount A, a coincidence detection section 908 that detects coincidence between the data amount stored in the buffer 907 and the data amount A stored in the storage section 921, and an output control section 920 that outputs the data stored in the buffer 907. When the data amount stored in the buffer 907 reaches A, the data are outputted from the buffer 907, and when the buffer 907 is empty, the data amount stored in the storage section 921 is written into A+Δ, and the data sent via the Internet are stored in the buffer 907. When the data whose amount is A+Δ are stored in the buffer 907, the data output from the buffer 907 is restarted.

Title: Preparation of spherical calcium carbonate
Inventor: TANABE KATSUYUKI
IPC: C01F11/18
Filed: 1989-11-27
Abstract: PURPOSE:To effectively and readily prepare spherical calcium carbonate having a high practical value in a simple process by heating the spherical dry aggregate of the calcium carbonate at a specific temperature in a CO2 atmosphere. CONSTITUTION:The spherical dry aggregate of calcium carbonate is heated at a temperature of 700 to 950 deg.C in an atmosphere having a carbon dioxide concentration of 3-100vol.% to prepare spherical calcium carbonate comprising a calcite type calcium carbonate sintered product. On the thermal treatment, since the calcium carbonate releases carbon dioxide at 600-650 deg.C in the atmosphere to be changed into calcium oxide, the calcium carbonate can not be sintered at high temperature, and the sintering of the calcium carbonate does not proceed at a temperature of <=600 deg.C because the temperature is too low. The thermal treatment is thereby preformed in a gas containing >=3vol.% of carbon dioxide. When the temperature of the thermal treatment is lower than 700 deg.C, a long time is required to reduce the efficiency of the preparation work, and when exceeding 950 deg.C, the calcium carbonate has a danger to decompose into calcium oxide.

Abstract: PROBLEM TO BE SOLVED: To prevent a boundary part between an outer diametral fin part and a spherical surface part from folding inside during its molding under heat and pressure by a method wherein a curved surface is formed at the boundary part between the outer diametral fin part and the spherical surface part. SOLUTION: A stock 1 for molding an optical element is made of a polyolefin-based resin such a polyethylene, polypropylene or the like and consists of outer diametral fin parts 2 and spherical parts 3. In addition, at the boundary part between the outer diametral fin part 2 and the spherical part 3, a curved surface A having a curvature radius of 0.05-1mm is formed. A dumbbell-shape consists of a plurality of stock parts for molding optical elements is molded, first of all, by an injection molding and then separated by cutting in order to produce the stocks for molding the optical elements. Instead of the curved surface A, a chamfering part B may well be formed at the boundary part between the outer diametral fin part 2 and the spherical part 3 of the stock 1 for molding the optical element.  In this case, when the width of the chamfering part B is 0.05-1mm, the similar effect as the curved surface A can be obtained.

Title: Weather map drawn by interference fringe between two sheets of glass
Inventor: KAWADA JUNICHI
IPC: G01W1/00
Filed: 1990-11-08
Abstract: PURPOSE:To prepare isobaric lines by stacking two sheets of glass one on the other, and placing weights on the respective centers of an anticyclone and a cyclone, and illuminating the sheets of glass from above using a sodium lamp, and drawing a weather map using interference fringes between the two sheets of glass. CONSTITUTION:Sheets 2, 2' of glass are stacked on a map 1 drawn by white lines on a black background. The sheets of glass are illuminated by a sodium lamp 3 from above. When some weights 4, 4' are placed on the map 1 in such a manner that the center of an anticyclone and that of a cyclone correspond to the respective weights 4, 4', the upper sheet 2 of glass is distorted and a slight change in the space between the sheets of glass is caused. Since the sheets of glass are illuminated by the sodium lamp 3 of single-colored light from above, interference fringes 5 of light are formed at intervals corresponding to pressure. A precise weather map can thus be drawn by setting the weights 4, 4' with accuracy. Besides, the fringes would not cross each other on account of the nature of the interference fringes.

Abstract: PURPOSE:To lower allowable working accuracy so as to improve the productivity and production yield by forming a shallow groove every certain number of thread grooves in a first rolling process, and rolling in the shallow groove in a second rolling process so as to gather thread ridges while putting the deep groove between. CONSTITUTION:In a double-start thread part 120 made by a first rolling, a shallow groove g10 and a deep groove g20 are alternately formed. Further, in this double-start thread part 120, the angles of the thread grooves g10, g20, namely, the angle (alpha) pinched with opposed flanks is constant and only the depth (a), (b) are different from each other.
