Title: Master slice semiconductor integrated circuit device
Inventor: HASHIMOTO MASAMI
IPC: H01L27/04
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To construct a path transistor logic circuit efficiently by cutting off each gate electrode and the drain or source electrode of n-type and p-type MOSFETs excluding a wiring layer, and besides, making the number of pieces of n-type MOSFETs three times the number of pieces of the p-type MOSFETs or over. SOLUTION: As against the two pieces of P-type MOSFETs 11 and 12, n-type MOSFETs 13-18 are three times as many as the P-type MOSFETs 11 and 12. Moreover, the gate electrode, the drain electrode, and the source electrode of each MOSFET are independent, not being held in common, and a circuit is not made until formation of two or more wiring layers. Hereby, with respect to a semiconductor integrated circuit device being suitable for a path transistor circuit which has such characteristic that the number of transistors is small and the power consumption is low, a master slice semiconductor integrated circuit device for a path transistor in the same cost and the same number of manufacture days as a semiconductor integrated circuit for a master slice (gate array) can be obtained.

Abstract: PURPOSE:To prevent a so-called chopping phenomenon by which the speech sending signal is interrupted and to improve the speech quality, by detecting the speech receiving level by means of an attenuator having the value depending on the speech sending level in the speech sending mode. CONSTITUTION:A half echo suppressor is provided with a control suppression switch 2 inserted into a speech sending channel 12, a speech reception detecting circuit 4 which is inserted into a speech receiving channel 13 from a control speech reception loss 3 and the level of the speech receiving signal, a region deciding circuit 5 which detects the calling state from both the speech sending and receiving levels, and a control circuit 6 which controls the switch 2 and the loss 3 from the result of decision. In addition, a variable loss circuit 8 is provided. The loss of the circuit 8 is controlled by the output of a speech sending level detecting circuit 7. Then the speech receiving signal is applied to the circuit 5 via the circuit 8 in a speech sending region. Thus a chopping phenomenon never occurs even if a remote subscriber interrupts the calling since the loss 3 is inserted.

Title: Transformer with t shaped bus duct
Inventor: KAMODA KOUJI
IPC: H01F27/04
Filed: 1982-09-03
Abstract: PURPOSE:To eliminate the matching work of a transformer attributable to a difference in dimension at a site of installation and lessen a load applied to the bushing of the transformer by installing a terminal box to the side of a cubicle and a flexible conductor is connected between a bus bar and the terminal of a transformer. CONSTITUTION:A T shaped bus duct 2' is not installed to the main body of a transformer 1 and it is installed to flanges 7', 9' at the side of cubicles at a site of installation. After installing the T shaped bus duct 2' to cubicles 6', 8', a transformer terminal 4' is connected to a bus bar 5' (bus duct terminal) by a flexible conductor 41. Since the flexible conductor 41 has some degree of freedom in dimension and certain flexibility, it is capable of easily absorbing a certain difference in dimension, even if there is a difference in dimension between the main body of a transformer and cubicles. Since the weight of the bus duct is supported by the cubicles, it is not necessary to fix one side of the bus duct to the main body of the transformer.
