Filed: 1981-02-25
Abstract: PURPOSE:To obtain a transistor with small junction capacitance and enabling high speed switching by a method wherein the junction capacitance of the lateral extension of each junction is reduced to make the junction effective. CONSTITUTION:On a silicon substrate 1 formed by a normal bypolar, embedded process, a trapezoidal epitaxial island 5 or the side of the island etching processed comprising three layered substrate structure consisting of an epitaxial layer 2, an embedded layer 3 and a nitride film 4 is inversely tappered. Then an insulating oxide film 6 is formed by means of oxidizing within an oxidative atmosphere while the angle theta made by the surface of an epitaxial layer and the side of the oxide film may exceed 90 deg. by means of properly selecting the said inversely tapered angle to reduce the junction area. Through these procedures, the junction capacity of the junction 7 of the emitter base and the junction 8 of the collector may be reduced.

Abstract: PURPOSE:To obtain glass having a desired refractive index by a simple device at a relatively low temperature, by blending a solution of ammonium silicate with an ion different from the ion contained in the solution, gelatinizing the solution, and making it into glass under heating. CONSTITUTION:A solution of ammonium silicate is blended with an ion different from the ion contained in ammonium silicate.

Title: Subsidiary connection termination system
Inventor: SAKAI MASAKI
IPC: H04Q3/42
Filed: 1995-02-16
Abstract: PURPOSE: To dispense with a terminating switch of a balanced transmission tune by transmitting a signal only when the gate circuit of a speech channel device receives the signal showing its own connection from a circuit system device and then stopping the transmission of signals to the non-connected circuit system devices. CONSTITUTION: When a circuit system device 2 is connected to a speech channel device 1, a connection signal transmission member 11 contained in the device 2 notifies a gate circuit 10 of the device 1 of the connection of the device 2 itself. The circuit 10 transmits a signal to the device 2 only when the signal showing its own connection is received from the device 2 and stops the transmission of signals to the non-connected devices 2. Therefore, the termination of a balanced transmission line is not needed and no terminating switch is required neither. In this instance, a wiring 12 is added to the device 2 to transmit a signal to the device 2 that is connected to the subsequent stage of its own one. As a result, it is easy to connect together the devices 2 subsidiarily and one after another.
