Title: Leak point detecting method for gas filled cable
Inventor: EBISAWA FUMIHIRO
IPC: H02G15/28
Filed: 1993-12-27
Abstract: PURPOSE:To allow easy, quick and accurate detection of leak point even for an untrained techinician by adding a different odorant previously to a gas in a gas filled cable and identifying the odorant in leaked gas using an odor sensor. CONSTITUTION:A crystal oscillator odor sensor is employed for identifying the odor and deciding the quality thereof. An air suction unit 7 sucks the air to be measured, at first, at a rate of 1000cc/min through a sensor head 6 having the crystal oscillator odor sensor. A frequency counter 8 then reads out the fluctuation in frequency caused by the odorant adhered to a polymer material applied to the crystal oscillator. The fluctuation in frequency is then processed by a computor 9 and compared with prestored adhesion characteristics of each odorant thus identifying the odorant. This method allows easy, quick and accurate detection of leak point even for an untrained techinician.

Inventor: KOJIMA YASUTAKA
IPC: B60N2/06
Filed: 1992-12-11
Abstract: PURPOSE:To easily secure flatness of a part on which a roller slides by providing an engagement hole formed so that it does not reach the sliding part on a lock plate where a lock system is supported on an upper rail free to revolve and on a bottom wall and a side wall of a lower rail. CONSTITUTION:In a state where a lock plate 72 of a lock system 7 is engaged with an engagement hole 73 and regulates sliding of an upper rail 4 against a lower rail 3, when a rotation shaft 71 is operated to rotate against energizing force of a spring 75, the lock plate 72 simultaneously rotates and engagement with the engagement hole 73 is released. Consequently, sliding of the upper rail 4 against the lower rail 3 is allowed, and adjustment of a vehicle longitudinal position of a seat 9 becomes possible. Additionally, when rotational operation of the rotation axis 71 is stopped after positional adjustment of the seat 9, the rotation shaft 71 is rotated by the enrgizing force of the spring 75, the lock plate 72 and the engagement hole 73 are engaged with each other again and sliding of the upper rail against the lower rail 3 is regulated.

Title: Jig for film formation
Inventor: SAKAMOTO HIROKAZU
IPC: C23C16/50
Filed: 1989-12-20
Abstract: PURPOSE:To prevent the plasma damage of a formed film by constituting the jig of a holding part which holds the periphery of a substrate and an electrical insulating material which is provided in the part of the holding part in contact with the substrate. CONSTITUTION:This jig for film formation consists of the holding part 2 and the slender plate- or bar-shaped electrical insulating material 6. The substrate 1 is placed on the electrical insulating material 6 and the peripheral part 7 of the substrate 1 is brought into contact with the electrical insulating material 6 and is held via this material on the holding part 5 in the case of formation of a conductive film. The conductive film is then formed by utilizing the plasma. Since the electrical insulating material 6 is interposed between the rear surface of the substrate 1 and the step part 4 of the holding part 5 at this time, the film and the holding part 5 do not electrically connect to each other and the film is not fixed to an earth potential and has the floating potential corresponding to the potential in the plasma space. The potential gradient of the plasma space with the film, therefore, decreases and the acceleration of the charge particles in the plasma toward the film is eventually prevented.

The movement of the magnetic walls is smoothed in this way and the extremely small coercive force is obtd. The magnetic head material having the high saturation magnetization based on the characteristics of the pure iron is obtd.

Title: Emphasized electronic expression generator
Inventor: RAINERU ESHIYUBATSUHA
IPC: G06T5/00
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a copy with features more emphasized than those of an original document. SOLUTION: A scanner 10 generates a 1st set of an M-bit signal representing an image in a document. A default table interprets the M-bit signal into a linearized N-bit signal (M is larger than N). A color image processing module 12 processes the N-bit signal to generate an image dependent lookup table, which is loaded to the scanner 10. Then the scanner scans again the same image with high resolution to generate a 2nd set of the M-bit signal. The 2nd set of the M-bit signal uses the image dependent lookup table and is interpreted into the N-bit signal and the electronic expression with emphasized characteristics is generated.

Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To effectively utilize energy at start-up by taking out the rotational power of rational shaft for running a vehicle in linkage with a brake pedal, and converting the power into compression air and storing it. SOLUTION: In the case where an indication of a pressure meter 58 reaches P1 when a brake pedal 51 is pressed down strongly, an opening and closing valve is closed, and thus the pressure oil (P1 or more) caused by the pressing down of the pedal 51 is supplied to only an engine speed increasing rate control cylinder 56, thereby bringing its piston into the downstroke state for advancing a control shaft to the arrow A direction. As a result, a friction roll advances to increase the engine speed conversion ratio of a conical surface frictional transmission 24 to thereby increase the rotational frequency of an output shaft 13 and transmit it to a rotary compressor 26, resulting in generation of a lot of compresion air. In this way the energy generated by the running of a vehicle is converted into the compression air by the compressor 26 and it is stored in a high pressure tank 27.
