Title: Controller and control method for a plurality of switching output stages and power amplifier
Inventor: SCHWEIGHOFER PETER
IPC: H03K17/64
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To prevent unbalanced loading on the output stages due to the energy being fed back or other effects by assigning a plurality of pattern signal groups to respective switching output stages and exchanging the assignment for every section. SOLUTION: A controller comprising a signal generator 28 and a switching unit 30 controls switching output stages 10, 10'. The output stages 10, 10' are connected with switches 36, 36' through control connection lines 40, 40'. At a first switching positron, signals in a first pattern signal group arriving through a pattern signal connection line 34 are delivered to the control connection line 40 and signals in a second pattern signal group arriving through a pattern signal connection line 34' are connected to the control connection line 40'. Subsequently, the switches 36, 36' are turned to a second switching position in order to exchange the assignment such that the signals in the first pattern signal group are applied to the control connection line 40' and signals in the second pattern signal group are applied to the control connection line 40.

Title: Electronic device with anodic oxide film, and etching of anodic oxide film
Inventor: SHIMOMAKI SHINICHI
IPC: H01L21/306
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To provide an electronic device having an anodic oxide film by conducting a small number of lithographic processes. SOLUTION: A Ta film 13, which has an etching selectivity ratio with an Al film 2, is formed on the Al film 12, and the film is patterned. A TaOx film 16 and an AIOX film 17 are formed by anodic oxidizing the laminated films. By having the above-mentioned structure, the etching selective ratio between the base layer Al film 12 and the Ta film above the film can be determined 12. As an anodic oxide film can be removed easily, the masking process using the resist of the Al film is unnecessitated, and the number of photolithographic process can be reduced.

Title: Semiconductor pressure sensor
Inventor: KATSUMATA BUNJI
IPC: G01L9/04
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor pressure sensor wherein by reducing the number of components the number of assembly processes can be reduced for less assembly cost, volume fluctuation of oil depending on temperature change can be suppressed for easy oil sealing. SOLUTION: An insulating material 60 is poured in a housing recessed part 12 to seal up a semiconductor pressure-sensitized chip 20, a wire 55, and a lead terminal 50, after an opening 14 of the housing recessed part 12 is stopped with a metal diaphragm 30 an oil 40 is packed into a gap formed between the insulating material 60 and a metal diaphragm 30, so that the wire 55 and the lead terminal 50 do not directly touch the metal diaphragm 30 when the wire 55 is oscillated or the metal diaphragm 30 is displaced, for eliminating a factor causing short. only packing the oil 40 in the gap is sufficient. Since the insulating material 60 has been poured in the housing recessed part 12 by a specified amount, the packing amount of the oil 40 is less by that amount, for suppressing volume fluctuation of the oil 40 depending on temperature change.

The signal current for controlling through the diode 34 is in the order of mA, the variation as the control signal to the temperature change of the diode 34 can be ignored. The main control is applied as the voltage and the sub control can be applied as the current to the constant voltage characteristic.

Filed: 1992-02-06
Abstract: PURPOSE:To perform an alignment operation accurately by a method wherein an alignment pattern for alignment use can be aligned on the basis of its upper and lower positional relationship and its right and left positional relationship on a plane when element constituent patterns are aligned with each other in the manufacture of an electronic element. CONSTITUTION:An n-type conductive layer 14 as a first pattern is formed on a p-type silicon substrate 13. At this time, alignment patterns 10, 11, 12 which are required to manufacture a bipolar IC and which are used as references for mutually positioning individual conductive layers to be formed later are formed. Then, an n-type silicon layer 15 having a film thickness of about 10mum is deposited; a p-type conductive layer 16 is formed on its surface. The position of the p-type conductive layer 16 is decided in such a way that alignment patterns 1, 2, 3, 4, 5, 6, 7, 8, 9 accompanying the p-type conductive layer 16 are aligned with the alignment patterns 10, 11, 12 for the n-type conductive layer 14 as the first pattern. Thereby, an alignment operation can be performed without overlapping the alignment patterns via the silicon layer whose film thickness is about 10mum.
