Title: Controller for thyristor converter
Inventor: AZUSAWA NOBORU
IPC: H02P7/292
Filed: 1983-01-21
Abstract: PURPOSE:To prevent the commutation failure of a converter with the end limited value as the necessary minimum limit value by limiting a phase control signal by the sum of a superposed command value and a margin angle command value and then converting it to a control value by reverse cosine calculation. CONSTITUTION:A thyristor converter 1 for driving a DC motor 3 is controlled by a phase control signal Ralpha in response to a deviation between a current command and a current detection signal through a phase angle limiter 8, a reverse cosine calculator 9 and a pulse generator 10. At this time, a limiter 8 is composed so that the output of a superposing angle calculator 11 and a commutation margin angle set signal Rgamma are added to output an end limited value R and applied to a proportional calculator 13 to produce a phase angle command Ralpha'. Accordingly, since the end limit is limited before converting to the control angle by the calculator 9, and the commutation failure can be prevented by reducing the end limited limit to the minimum value irrespective of the nonlinear property of the load current and the superposing commutation angle.

Title: Manufacture of solar battery
Inventor: OOTAKE TSUTOMU
IPC: H01L31/20
Filed: 1982-01-20
Abstract: PURPOSE:To improve the performance of the solar battery, by continuously changing the doping amount of boron without changing a total gas flow rate, thereby giving a gradient to the impurity concentration in a P layer. CONSTITUTION:The temperature in a water bath 21 is detected by a thermocouple 25. The signal is fed back, and the flow rates of warm water through an inlet port 22 and cold water through an outlet port 23 are controlled. Thus the temperature of boron tribromide (BBr3) is kept at a specified temperature. When H2 gas is flowed from a gas introducing pipe 27 and the H2 gas is discharged from a discharge pipe 28, BBr3 is included in the BBr3. The amount of inclusion depends on the vapor pressure of BBr3, and said amount is controlled by the temperature of the water bath. The discharged H2 gas is introduced into a reacting chamber of a plasma CVD apparatus, and the plasma discharge is performed together with SiH4 gas. Then an a-Si film including the boron is formed. When the temperature of the water bath is charged, the amount of the boron included in the a-Si is changed.

Title: Direct spread spectrum communication system
Inventor: OKAMOTO NAOKI
IPC: H04B1/707
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To provide a spread spectrum communication system based on a direct spreading system hardly causing mutual interference even when the band of the same frequency is shared. SOLUTION: At a spreading part 2, a signal from a data transmission part 1 on the side of transmission is spread by a code generated by a spreading code generating part 21. The chip rate of spread is controlled by a chip rate control part 22. On the side of reception, the input signal from the antenna is converted by a frequency converting part 5, inversely spread by an inverse spreading part 6 and demodulated by a demodulating part 7. Inverse spreading is performed by operating the inverse spreading part 6 while controlling a spreading code generating part 61 through a chip rate control part 62. When the chip rate of one system defines an L spreading rate as (k) for preventing interference, the chip rate of the other system becomes (L/k)×m (m: 1, 2, 3...). In this case, the spreading cycle of one system is inserted into one chip on the other side for one cycle.

Filed: 1995-01-23
Abstract: PURPOSE: To provide a conductive film that can be readily manufactured at low temperatures and is low in resistance by consolidating a conductive-particle- containing layer through the shrinkage of layers that touch the conductive- particle-containing layer. CONSTITUTION: This conductive film is formed by a layered structure consisting of a plurality of layers such as a glass substrate 3, a conductive layer 2, and a conductive-particle fixing layer 1, and conductive particles contained in the layer 2 have their contact area increased by the layer 1 which shrinks instantaneously and simultaneously with film formation. The layer 2 containing the conductive particles is thus consolidated by using as a driving force the shrinkage of the layer 1 which occurs during film formation, so that with the conductive particles promoted to make contact with one another, the film which exhibits conductivity can be obtained. Also, the conductive particles contained in the layer 2 are desirably transparent and have no absorptions in the visible range.  The layer 2 is desirably manufactured by applying a solution in which the conductive particles are dispersed, then applying an alkoxide solution thereon, and consolidating the conductive-particle-containing layer.

Abstract: PURPOSE:To enhance safety and reliability by protecting semiconductor elements and an apparatus against an undue external surge energy due to lightning or an excessive AC voltage due to erroneous connection. CONSTITUTION:The power supply 10 comprises an AC input section 1', and a DC power supply section 2 including a switching regulator 8.

Title: Solid salt for hard water softening apparatus
Inventor: KAWAHITO AKIYOSHI
IPC: C02F1/42
Filed: 1984-01-20
Abstract: PURPOSE:To improve the performance of a hard water softening apparatus and to prolong the life of an ion exchange resin by using pelletized powder salt by adding an activating agent for the regeneration of ion exchange resin in a hard water softening apparatus. CONSTITUTION:Powder salt is pelletized by adding an activating agent such as a chelating agent. When the solid salt is used in a salt water device for regenerating an ion exchange resin for a hard water softening apparatus, formation of salt bridge is reduced remarkably improving penetration of water and facilitating dissolution of the salt because the voids among the solid salts are small and contacting parts of the solid salts with each other are also small. Accordingly, the concn. of the salt soln. can be attained to a specified satd. concn. in a short time. Further, Fe and Mn deposited to the ion exchange resin during the softening stage are masked by the activating agent during the regenerating stage and can be easily dissolved and removed. Therefore, sure regeneration of the ion exchange resin is realized.
