Title: Semiconductor pressure sensor and its manufacture
Inventor: TERADA MASAKAZU
IPC: H01L21/306
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor pressure sensor in which a recessed part can be formed simply and with good accuracy on the surface of a single-crystal silicon substrate, and to provide its manufacturing method. SOLUTION: A single-crystal silicon substrate, whose surface plane direction is a (100) plane is used as a single-crystal silicon substrate 1. A recessed part 3 is formed on the surface of the single-crystal silicon substrate 1. A diaphragm formation film is arranged on the surface of the single-crystal silicon substrate 1 so as to close the opening part of the recessed part 3. A through-hole 4 for etchant injection which is used to form the recessed part 3 is formed in the diaphragm formation film. The through-hole 4 is a slender cross shape which is extended to <110> directions of the single-crystal silicon substrate 1. In an etching operation to form the recessed part 3, a (111) plane is hard to be etched in the single-crystal substrate 1 on the (100) plane.  As a result, in the <110> directions on the single-crystal silicon substrate 1, the etching operation is stopped by the (111) plane in end parts of the through-hole 4 for etchant injection.

Title: Simple scramble system
Inventor: OSAWA KAZUAKI
IPC: H04J3/06
Filed: 1988-11-22
Abstract: PURPOSE:To simply scramble data on a time division multiplex line by executing the transformation of a time slot (multiplexing position) in synchronism with a transmission side and a reception side in a time division multiplexing device or an external device in the transmission side and reception side. CONSTITUTION:When NXN switches 1 and 2 are made through, the data on a multiplexing line 5 are from a line input terminal I1 and samely, the data from a line input terminal I2 to a line input terminal In go into the second time slot to an n-th time slot. On the other hand, when the NXN switches 1 and 2 are driven by a scramble synchronizing signal 6, it is not fixed for the data on the multiplexing line 5 which time slot on a frame the data on a certain line go in. For example, the data from the line input terminal I1 are in the first time slot as I11 in a frame 1. However, the data are in the n-th time slot as I12 in a frame 2. Thus, the data on the time division multiple line can be simply scrambled.
