Title: Air/fuel ratio detecting device
Inventor: OKAZAKI KAZUHIRO
IPC: G01N27/26
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To improve precision in air/fuel ratio detection while detecting the air/fuel ratio in a wide range. SOLUTION: An A/F (air/fuel ratio) sensor 30, following the voltage application under instruction of a microcomputer 20, outputs a liner air/fuel ratio detection signal, which is proportional to the oxygen concentration in the discharged gas from an engine 10. The microcomputer 20, with an applied voltage fixed in stoichiometric control area, lean burn control area, atmosphere detection area and a rich control area, allows a change factor of an applied voltage to the A/F sensor 30 to be smaller than other areas, at that area. Each area corresponds to the area where detection precision of air/fuel ratio is required. In addition, the microcomputer 20, when changing the voltage applied to the A/F sensor 30, sets a change speed of application voltage, for each sensor current value (air/fuel ratio), to be sequentially variable.  With this configuration, with no effect of capacitance (capacitor) characteristics of the A/F sensor 30, a voltage is applied to the sensor 30.

Title: Communication equipment
Inventor: KIMURA MASASHI
IPC: H04N1/00
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To provide a communication equipment with which image data and audio data can be received by one time of call connection, and the recorded audio data and image data can be handled as related information. SOLUTION: When a call from a line is detected in a voice response mode such as at the time of automatic recording, a voice message automatically responds to the call (step S201) and voice data of an opposite party are recorded (steps S202-S204). At such a time, when a CNG signal from the opposite party is detected (step S204), image reception is performed (step S205) and received image data are stored in a DRAM. Then, managing information for handling the voice data and image data recorded by one time of call connection as related information is stored in a RAM and suitable display processing is performed so as not to leave either the reproduction of recorded voices or the recording of received image in the case of voice reproduction or image recording.

Title: Time indicator and evaporator
Inventor: ITO TATSUE
IPC: G01N33/00
Filed: 1989-12-27
Abstract: PURPOSE:To discriminate an end point by the volatilization of an org. compd. which is liquid at ordinary temp. and to easily adjust the end point according to the amt. of the compd. to be used as well as to provide the device which is economical and is smaller in size by using the above-mentioned compd. CONSTITUTION:A container 1 of the evaporator is preferably a container made of glass or the like which allows the checking of the content from the outside. A mixture 2 composed of an electron donative colorable org. compd., a compd. having a phenolic hydroxyl group and the org. compd. which is liquid at ordinary temp. and/or perfume is injected into the container 1. A replenishing wick 3 consisting of felt or the like as a base material is immersed into the mixture 2. The time indicator is not colored at the time of the start of the use thereof. The desensitization effect of the org. compd. which is liquid at ordinary temp. weakens when the org. compd. volatilizes to some volatilization quantity as time passes by. As a result, the color developing effect possessed by the compd. having the phenolic hydroxyl group is intensified and the coloration of the electron donative colorable org. compd. begins. The end point of the volatilization is thus discriminated.

IPC: G06F19/00
Filed: 1991-12-26
Abstract: PURPOSE:To provide a limitation satisfying system which can acquire the limita tion relief propriety and its method and degree from a proper knowledge source and then can relieve exactly and effectively the limitation based on the accurate knowledge of a concrete state. CONSTITUTION:A limitation relief necessity detecting means 3 detects the necessity for the limitation relief of the problem solving cycle of a problem solving part 1. Then a relief subject limitating condition selecting means 4 is started to select the limiting conditions to be relieved out of the limitating condition groups and retrieves a limiting condition relief knowledge control means 2. A limiting condition relieving means 5 checks whether the relief grant conditions are satisfied by a partial solution or not. If so, the means 5 tries to relive the limitation based on the relevant recorded relieving method. When the limitation is relieved, the means 3 decideds the limitation relief propriety. Thus the control returns to the problem solving cycle of the part 1. If it is not impossible to clearly decide the possibility of relief for the specific limiting conditions, the means 5 inquires of the outside of a system about the decision of the relief propriety.

Title: Feed forward amplifier
Inventor: MORI KAZUTOMI
IPC: H04B1/04
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To reduce loss and to make efficiency to be high without damaging linearity by constituting the delay circuit of a main amplifier output circuit with a waveguide delay circuit where a high harmonic suppression filter in which inductances and capacitances are provided for multiple stages is formed. SOLUTION: The delay circuit of the main amplifier output circuit is composed of the waveguide delay circuit 101 where the high harmonic suppression filter in which the inductances of series charge and the capacitances of parallel charges are provided in the multiple stages is formed. The waveguide delay circuit 101 is used as the delay circuit of the main amplifier output route 10 of a distortion removal circuit 2.

Furthermore, it is not necessary to provide a high harmonic suppression filter between a feed forward amplifier and an antenna, and loss between the amplifier and the antenna can be reduced. Then, efficiency can be made efficient without damaging linearity.
