Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To realize an efficient class-A driver circuit capable of forming an optimal output stage to different loads. SOLUTION: The class-A driver circuit 30 has an output stage equipped with plural selectable current sources 42. The selectable current source 42 optimizes the driving ability of the output stage to different uses having different output impedance. The selectable current source 42 can be selected or switched using a software. Then, the current source can be automatically selected based on the detection of an output current supplied to resistive load. Or the selectable current source 42 can be selected based on the input signal of a 1st stage amplifier 32. A mirror compensating network 40 includes a capacity digitally controlled and switchable, and provides mirror compensation by a necessary quantity to thus selected current source.

Title: Portable terminal
Inventor: HOSHINA TAKAYA
IPC: H04W88/02
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To easily identify a terminal of its own from other terminals by encoding an inputted voice to store it as incoming tone data, decoding the incoming tone data and outputting a reproduced voice as an incoming tone at the time of receiving an incoming request. SOLUTION: When an incoming tone registering mode is set, a voice encoding/decoding part 4 encodes an optional voice that is inputted from a microphone 6 and a DMA controller 3 stores it as incoming tone data in a specific area of a RAM 2 without being passed through a processing part 1. At the time of an incoming call, the controller 3 reads as much data as is designated and transfers it to the part 4. Thereby, a voice that is optionally registered by a user is outputted as an incoming tone. Further, an originator's number is corresponded to incoming tone data and stored, and when an originator's number that is included in an incoming request is a stored originator's number, corresponding incoming tone data are decoded and the originator is identified by a reproduced voice.

Title: Test signal generating device
Inventor: ISHIBASHI MASAHIRO
IPC: H04H40/36
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To shorten setting time and minimize memory capacity by providing a memory for storing an arbitrary waveform, a switching part for inputting a sine wave signal from a sine wave generator followed by switching, a modulator, and an adder for adding the output from the switching part to the output from the modulator. SOLUTION: A memory 1 stores a two-tone signal as an arbitrary waveform. A control part makes a selector 31 select non-signal, and makes a selector 32 select a sine wave generator 2. Thus, the data of the memory 1 is not utilized. A modulator 4 inputs the sine wave signal outputted by the generator through the selector 32, and performs FM modulation. An adder 5 adds the non-signal from the selector 31 to the signal from the modulator 4 and outputs the result as a test signal. This test signal is D/A converted and imparted to a target to be tested, and an IC tester performs its test. When a signal in which the two-tone signal is modulated is outputted, the control part makes the selector 31 select the non-signal, and makes the selector 32 select the memory 1.

Title: Stack information collecting system using timing of return processing
Inventor: MIZUSHIMA SATOSHI
IPC: G06F11/28
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to collect program stacking information to which reference is usually disabled due to overwriting caused by the repetition of function calls and returns by integrating a storing function inside by using the timing of a return at the time of compiling. SOLUTION: When a source 11 is compiled by a compiler 12, a stack information processing routine is integrated in a text part of an object 10. The routine is read out from each function immediately before a return instruction to transfer stack information to a stack information storing area 6. When the area 6 is filled with the stored stack information or a program 1 has ended, the stack information stored in the area 6 is outputted to an output device 9. Since stack information to be communicated with respective functions can be referred to at the occurance of a fault in the program 1, the program 1 can easily be analyzed.

Filed: 1991-11-29
Abstract: PURPOSE:To improve sealing capability and make the treatment during pipe fixing easy by deposition fixing an earth ring formed by mixing powder electroconductive material on the lining material surface covering the outer surface of flange of a measuring pipe. CONSTITUTION:An earth ring 20 is formed to a specified plate thickness by mixing such powder electroconductive material as platinum and carbon particles in a main material (fluoric resin and the like) made of the same material as the lining material 10 lined inside wall of a measuring pipe 1. This is deposited and fixed on the surface of the lining material 10 covering the outer surface of the flange 1a of the pipe 1. As for the deposition and fixing method, there are a resistance welding method, heating deposition method, welding method and rotation contact method etc. On the outer surface of the flange 1a, an annular ant groove 21 is formed, which prevents exforiation of the lining material 10. As the periphery of the ring 20 is not contacted to the measured fluid and corrosion resistivity is not required, use of rare metal is reduced. Thus, liquid leak out of the contact part between the ring and the lining material 10a can be prevented.
