Title: Air conditioning system for motor vehicle
Inventor: NAGANO HIDEKI
IPC: B60H1/00
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To regularly and surely detect the degree of contamination of air by providing a gas sensor having a structure for introducing static pressure without receiving dynamic pressure and never generating blowing sound. SOLUTION: In a blower 8, a nose part 25 is formed in the scrolling start part of a blower case 21, and an air outlet port 26 is formed in the middle of a side wall 25a facing the blowout port for forming the nose part 25. An air outflow passage 27 is connected to the air outlet port 26, and a gas sensor 20 for detecting the contamination of a toxic gas out of a cabin such as carbon monoxide, nitrogen oxide or the like is provided on the tip side thereof to detect the degree of contamination. Since the air outflow passage 27 having the gas sensor 20 takes the air from the air outlet port 26 formed in the middle of the side surface 25a facing the blowout port 24 of the nose part 25, the air having a large static pressure portion is obtained without receiving the dynamic pressure of the flowing air.  Further, the outflow speed is relatively gentle, so that the flowing air causes no blowing sound.

Title: Interference wave eliminating device
Inventor: TSUJIMOTO ICHIRO
IPC: H04L27/38
Filed: 1990-05-31
Abstract: PURPOSE:To eliminate the multipath distortion with respect to a desired wave by outputting a first discrimination signal from a first discrimination feedback equalizer as a desired signal to eliminate a wide-bank interference wave having the multipath distortion from a reception signal without damaging the diversity effect in an arbitrary D/U. CONSTITUTION:This device consists of matching filters 1 and 2, discrimination feedback equalizers 3 and 4, a convoluting part 5, an adder 6, subtractors 7, 13, and 14, an AGC amplifier 8, a multiplier 9, a linear filter 10, a correlator 11, a delay element 12 having a delay time eta, and a delay element 15 having a delay time gamma. A desired signal replica is subtracted from the reception signal without anti-phase synthesis of interference waves to extract an interference component, and an interference wave is subtracted from the extracted reception signal of a diversity route after control of the interference component, and the extracted interference wave is subtracted from the reception signal from another diversity route after linear filtering to eliminate the interference wave. Thus, the wide-bank interference wave having the multipath distortion is eliminated from the reception signal without damaging the diversity effect in an arbitrary D/U, and the multipath distortion of the desired wave is eliminated.

Title: Wavelength converting device
Inventor: INOUE YASUSHI
IPC: H01L31/0232
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To read information out of signal light of a wavelength conversion source by providing a means which takes a photocurrent, generated in an electric field absorption type optical modulator (EA modulator) corresponding to intensity-modulated signal light, out as an electric signal. SOLUTION: The electric signal is taken out of the EA modulator 1 through a bias T circuit 4 which applies a bias voltage supplied from a bias source 3 to the EA modulator 1. The absorptive saturation of the EA modulator is caused by the excitation of carrier electrons of the input signal light. Namely, the carrier electrons is generated corresponding to the input signal light at the time of wavelength converting operation. This is equivalent to the functioning of the EA modulator 1 as a current generating source. Here, an external circuit is connected to the EA modulator 1 and then the carrier electrons (photocurrent) generated at the time of the wavelength conversion can be taken out as an electric signal. This electric signal corresponds to the input signal light to the EA modulator 1 and information put on the input signal light can be read.

Title: Document editing device, information processor, and floppy disk driving device
Inventor: YAMAZAKI ISAO
IPC: G06F17/21
Filed: 1990-05-31
Abstract: PURPOSE:To attain the transmission/reception of a large quantity of data by loading a storage medium to one of floppy disk driving devices at all times and securing such specifications that inhibits the exchange of the storage medium for a fixed period. CONSTITUTION:A floppy driving device FDD 52 is provided exclusively for recording/reproducing the transmission/reception data in addition to another FDD 9 which reproduces an editing document floppy, a system floppy, etc. A single sheet of exclusive recording medium is always loaded to the FDD 52 so that the user of a document editing device is not required to exchange the recording medium. Therefore the FDD 52 always performs the self-recording/ reproducing operations to an exclusive medium and is not required to consider the interchangeability with other media. Thus it is possible to record/reproduce only the outer circumference side (only 2/3 track range of the outer circumference side) out of all recordable tracks of an exclusive recording medium. Thus it is not required to use the inner circumference track having the lowest image resolution. Then the constitution of a reproducing circuit is simplified.

Title: Rotary grinding tool with brake
Inventor: TAKANO HIROSHI
IPC: B24B23/03
Filed: 1995-06-09
Abstract: PURPOSE: To moderate shake caused when grinding is started to provide a beautiful finished surface having no flaw, and also shorten stopping time of a circular pad after a switch is turned off to improve the working efficiency by providing a plurality of blades on the upper part of the circular pad. CONSTITUTION: In a rotary grinding tool for performing a grinding work by an abrasive paper 6 held on the lower part of a circular pad 5, a plurality of blades 4 are provided on the upper part of the circular pad 5. Since the circular pad 5 is rotated only by inertial force generated by revolving motion of an eccentric shaft 2, the rotating number of the circular pad 5 is reduced by air resistance generated by the blades 4. Thus, shake caused when a material to be ground makes contact with the circular pad 5 can be moderated to eliminate a local grinding. Further, since the air resistance is generated in the blades 4 on the upper part of the circular pad 5 even after a switch 7 is turned off, the circular pad 5 can be stopped within a short time.
