Title: Digital direct phase modulation method and circuit
Inventor: SUGIURA MASAKI
IPC: H03B28/00
Filed: 1992-02-28
Abstract: PURPOSE:To reduce the storage capacity of a memory storing a waveform pattern. CONSTITUTION:Waveform data of a modulation wave to be outputted are stored into plural number, e.g. two ROMs 23, 24 in advance separately, and the plural waveform data read from the said two ROMs 23, 24 are timewise synthesized by a synthesis circuit 27 via inversion control sections 25, 26 in response to transmission data for each modulation phase, the synthesized data are converted into analog data by a D/A converter section 28 to generate a modulation wave corresponding to the transmission data. Thus, not all of the transmission data of a modulation wave to be outputted are stored in one ROM but stored in the plural ROMs separately and the waveform data are generated by combining the waveform data of the modulation wave.

Title: Fuel cell system
Inventor: NONOBE YASUHIRO
IPC: H01M8/04
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To adjust the humid state of an electrolyte film within an appropriate range by accurately determining the humid state of the electrolyte film in a solid polymer type fuel cell. SOLUTION: When a current at detected by an ammeter 42 and supplied from a fuel cell 30, is at a predetermined value, a humid state of an electrolyte film of the fuel cell 30 is determined based on a differential value of a resistance of the fuel cell 30 to be detected by a resistance detector 48. A conductive electrode or separator and a proton-conductive electrolyte film are laminated in the fuel cell 30. Although the conductivity of the electrode or separator is never influenced by the humid state, the proton-conductivity of the electrolyte film is greatly changed by the humid state. Consequently, a change rate (the differential value) of the resistance of the fuel cell 30 directly represents a change rate of the proton-conductivity of the electrolyte film. As a result, it is possible to accurately determine the humid state of the electrolyte film.

Title: Method for detecting end of etching of resist film
Inventor: NAKAMURA MORITAKA
IPC: H01L21/302
Filed: 1983-03-16
Abstract: PURPOSE:To detect the end of etching of a resist film easily by detecting variation of a light-emitting spectrum of hydrogen atom among the light emissions by the plasma generated in a reaction chamber at etching of the resist film in order to detect the end of etching. CONSTITUTION:The etching gas consisting of mixed gas of O2 gas and CO2 gas is introduced into a reaction chamber 1 from a gas introducing inlet 6. Nextly, high frequency electrical power is applied between a substrate carrying table 2 and an electrode. Consequently, the introduced etching gas becomes plasma- state in the reaction chamber 1 and emits the light. This emitted light is lead to a diffraction grating 8. The introduced light is divided into the lights various wave lengths and these divided lights are introduced into a light-detecting element 9 to convert the light signals into the electrical signals. The intensity of emission of hydrogen atoms is detected by the magnitude of said electrical signal. Since hydrogen atoms decrease when the resist film is removed and the reaction completes, the time when the hydrogen atoms decrease is detected as the time when the emission intensity of the hydrogen atoms decrease, thereby detecting the end of etching.
