Title: Manufacture for steel having super low hydrogen and super low sulfur content
Inventor: TAGIRI KOUICHI
IPC: C21C7/064
Filed: 1981-08-03
Abstract: PURPOSE:To produce the steel having super low hydrogen and supen low sulfur content  effectively in a single process by the following method in which when molten steel is  refined, desulfurizer is blown into the molten steel by controlled flow rate of inert gas  as a carrier, and then only inert gas is successively blown thereinto under reduced  pressure. CONSTITUTION:When molten steel is refined under reduced pressure in a ladle combined with a vacuum degassing tank, the internal pressure of said tank is reduced and  desulfurizer is blown into the molten steel such as killed steel which is fully deoxidized in a ladle 1 by using inert gas as a carrier. The flow-rate of this inert gas is  limited to less than the value of Q which is obtained by the following formula,  h/H=-0.25Q+2.8, where H is the distance between the interface of the vacuum atmosphere 3 and the ladle-bottom, and h is the distance between the interface 3 and the  spouting port 6 of a lance for injecting powder material; and the value is to be within an area (A) in the figure enclosed by a,b,c,d. After the desulfurizer has been injected  into the molten steel, the inside of the vacuum degassing tank is successively kept  vacuum and only inert gas is injected. By this process, the steel having super low  hydrogen and super low sulfur content may be manufactured in a stable condition.

Title: Vapor phase reflowing device
Inventor: SAITO SUSUMU
IPC: B23K1/015
Filed: 1987-05-20
Abstract: PURPOSE:To perform the reflow soldering with the high reliability without damaging electronic parts by setting up a preheater to preheat a printed circuit board in space in a mixed state of vapor with air to reduce the temperature rising speed of an object to be heated. CONSTITUTION:The printed circuit board 6 which is the object to be heated is carried by a conveyor 7 for carrying and first cooled by cooling coils 8 and then, heated by the preheater 9. The temperature of the preheater 9 itself is set at the same temperature as a boiling point of a liquid 10 for generating the vapor and the heater 9 heats the peripheral air to generate a convection 11 of the air and the printed circuit board 6 is heated. Since the air contains much vapor 13 of the liquid 10, it has the better heat transfer coefficient than the outside air. As a result, it is not necessary to raise the temperature of the heater 9 of its own high like an infrared heating heater and a sufficient effect is displayed. Then, since the heat transfer coefficient is lower than the saturated vapor of the liquid 10, the temperature rising speed of the circuit board 6 is reduced. After ward, the board 6 is put in the saturated vapor 13 and its temperature rises up to the reflow temperature.

Title: Synchronizing matching circuit
Inventor: NOIRI AKIRA
IPC: H04L7/00
Filed: 1990-05-15
Abstract: PURPOSE:To simplify the adjustment by using a frame phase difference and a bit phase difference in response to a delay in a frame signal sent from a data transmission section so as to vary the phase of a frame synchronizing signal and a clock synchronizing signal sent from a receiver side to a sender side. CONSTITUTION:A frame synchronizing data transmitter consists of a data transmission section 100 and a data reception section 200 which are operated by a same clock and a same frame. Then a frame phase difference and a bit phase difference are obtained in response to a delay of a frame signal returned from the data transmission section 100 being a suborinate station are obtained and the phase differences are used to vary the phase of a frame synchronizing signal (h) and a clock synchronizing signal sent (g) from a receiver side to a sender side. Thus, even when the distance between the transmission reception sections is changed, the frame bit synchronization between both the sections is established automatically and complicated manual operation for phase synchronization is not required.
