Title: Pleliminary heating method for sealing resin
Inventor: MATSUMURA KEIZO
IPC: H01L21/56
Filed: 1990-10-29
Abstract: PURPOSE:To obtain tablet type sealing resin capable of easy chucking without generating voids, by using granular resin as sealing resin. CONSTITUTION:Granular resin 9 for sealing, which is previously metered so as to be matched with a molded object, is encapsulated in a molding cylinder 1. An electrode 2 for high frequency induction heating as a heating means is arranged outside the cylinder 1. The resin 9 is heated by the heating means and begins to be softened. When the pressure of the inside of the cylinder 1 is suction-reduced via fine communication holes, water contents contained in the resin within the temperature range of preliminary heating evaporate and turn to water vapor. When a pressure is applied by a pressurizing rod 5, air gaps of the resin are crushed and air is pushed out, which is suction-exhausted outward while accompanying the water vapor. Thereby the preliminary heating of the resin is finished in the state that air and water contents are completely eliminated. The resin is molded in a tablet type capable of easy chuking by heating, and introduced in a molding process.

Title: Atomic absorption spectrophotometer provided with supporting-gas changeover device
Inventor: YAMANO YOSHIHIRO
IPC: G01N21/31
Filed: 1993-10-27
Abstract: PURPOSE:To detect, by a simple constitution, the increase in flow rate of a fuel gas when a supporting gas is changed over. CONSTITUTION:The output of a photodetector 20 is input to an operational amplifier 22a, and it is amplified. The output signal Vo of the operational amplifier 22a is input to a comparator 24a, and it is compared with a reference voltage Vr. When it exceeds the reference voltage Vr, a signal to change over a supporting gas is output to a gas controller 14b from the comparator 24a. In order to adjust the offset voltage of the operational amplifier 22a so as to correspond to the flow rate of C2H2 gas in an analysis, a D/A converter 28 is installed, a CPU 26a inputs, to the D/A converter 28, a signal to adjust the flow rate of the C2H2 gas in the analysis via a digital valve 12a, and the D/A converter 28 produces the offset voltage of the operational amplifier 22a so as to correspond to the signal. The offset voltage is controlled to a direction in which it is reduced when the flow rate of the C2H2 gas in the analysis is increased.

Title: Communication control equipment
Inventor: KOIZUMI YOSHIAKI
IPC: H04L29/10
Filed: 1987-11-18
Abstract: PURPOSE:To cause a partner station to recognize the completion of reception even in various communication atmospheres, by adding a carrier control equipment to a communication control equipment. CONSTITUTION:When transmission of transmitting data is completed and a communication controlling section 11 turns off a transmission request (a), the transmission request turning-off latch 124 and counter 125 of a carrier controller 12 start to work and, at the same time, the output of a transmitting data controlling FF 126 is set to '1'. Therefore, transmitting data (f) to a MODEM as the output of an OR circuit 127 for controlling transmitting data are mark-held. When the data (f) are mark-held, the transmission request (b) to the MODEM 3 is held in the turned-on state even if the transmission request (a) is turned off, since the output from an FF 122 to a circuit 123 is turned on. Since the counter 125 turns off the output of the FF 123 and sets the output of an FF 126 to '0' after the timing of one-character quantity, the transmission request (b) is turned off and the carrier to a partner station is turned off.
