Title: Digital signal reproducing device
Inventor: YAMASHITA NOBUITSU
IPC: G11B15/467
Filed: 1986-02-28
Abstract: PURPOSE:To attain excellent tracking control even when no special signal is recorded by applying the tracking control based on the relation between the rotating phase of a rotary head and the timing extracted from a data synchronizing signal in a digital signal reproduced from an azimuth track by the rotary head. CONSTITUTION:Assuming a delay time (tau0-tau1) of a timing (tau1) at which a data synchronizing signal is reproduced actually from a timing (tau0) when a reproducing rotary head is in the specified rotating phase as tau, then the reproduc ing rotary head traces a control object track accurately when the delay time tauis '0'. When tau>0, the reproducing head traces the track with a delay, the tape 1 is to be decelerated when the tape 1 is run in the direction of the arrow (y). When tau<0, the traced position is deviated in the opposite direction to the H with respect to the track T1 and the tape 1 is to be accelerated. Thus, the excellent tracking control is attained without a special tracking control signal.

Title: Electric carpet
Inventor: MURAMATSU TAKESHI
IPC: H05B3/00
Filed: 1990-02-26
Abstract: PURPOSE:To improve an interior characteristic of a carpet and further realize an antenna having efficient efficiency by a method wherein the carpet is provided with a communication part for transmitting or receiving a control data under a remote controlling operation or a display data of the remote controlling operation with a wireless electromagnetic wave. CONSTITUTION:As an operating part 2 for a remote controlling part 1 is operated, a set data is modulated into a wireless electromagnetic wave through a communication part 31 and then transmitted into the air through an antenna 4. Electromagnetic wave received through an antenna 6 within a main body 5 of the carpet is demodulated at the communication part 7 and sent to the control part 8. The control part 8 controls a heating member in response to a set data. Operating state information at the control part 8 is transmitted into the air through an antenna 6 from the communication part 7. Wireless electromagnetic wave received through the antenna 4 is demodulated at the communication part 3 and then sent to the operating part 2. At the operation part 2, the data is displayed at the display device in response to the received operation state information. The communication part 7 at the main body of the carpet can be sealed below the carpet since the electromagnetic wave is transmitted through the cloth of the carpet.

Title: Valve gear for internal combustion engine
Inventor: YORUMA POOYORA
IPC: F01L13/08
Filed: 1989-02-23
Abstract: PURPOSE: To raise combustion action efficiency and enhance combustion potential by providing a valve and a sleeve which is coaxial with the valve and moves in the same direction as the valve. CONSTITUTION: A bore is formed in a cylinder head 3. A sleeve 15 is slidably inserted in the bore. A suction valve 12 is movably mounted in the sleeve 15. A suction valve shaft 16 is coaxially arranged in the sleeve 15. During discharge, the sleeve 15 and the suction valve 12 are in a combustion space 5.

Filed: 1985-03-07
Abstract: PURPOSE:To prevent a surface potential from dropping and to obtain excellent images by providing a means for cutting a developing bias to a developing device which is positioned nearby an electrostatic charging device and not used for development while a selected developing device is in operation. CONSTITUTION:For example, when the (n)th developing roller 131n among >=2 developing rollers 1311-131n, and 131n+1 is used to perform development, the developing bias to developing rollers closer to the electrostatic charging device 15 than it is cut. When the (n+1)the developing roller 131n+1 is used for development, the developing bias to developing rollers closer to the electrostatic charging device 15 than it is cut. Namely, while a selected developing device of a developing device equipped with plural developing rollers is in operation, the developing bias to developing devices closer to the electrostatic charging device 15 is cut to prevent a drop in surface potential due to the contacting developer magnetic brushes of unused developing devices with a photosensitive drum before development is performed by the selected developing device. Consequently, excellent images are obtained.

Title: Image recorder
Inventor: KOKATSU HITOSHI
IPC: H04N1/407
Filed: 1992-03-03
Abstract: PURPOSE:To accurately execute color reproduction independently of an environmental change, a change with the passage of time, and so on. CONSTITUTION:A TRC 8 is provided with a serial connection of the 1st and 2nd LUTs 10, 11 for an image output part 9. The 1st LUT 10 compensates equivalent neutral density and has linear or approximately linear relation between an input and an output and the 2nd LUT 11 non-linearly compensates the density or lightness of the image output part 9. Thereby compatibility between a masking processing part and the TRC 98 can be improved and the coefficient of a masking matrix can be accurately determined, improving the accuracy of color reproducibility. A control device 14 enters data from a detection means 13 in the image output part 9 and rewrites the table of the 2nd LUT 11. Thereby even if the gradation/reproduction characteristics of the image output part 9 are changed, this image recorder can easily correspond to the change.

Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To provide a dielectric resonator which has a dielectric mounted on a support and can be easily and fast produced with high performance characteristic by using a high polymer material of a low dielectric constant to the support and fixing adhesively the dielectric and the support by means of the same material as that of the support. SOLUTION: A dielectric resonator 1 comprises a casing 11, a support 13 contained in the casing 11 and a dielectric 12 which mounted on the support 13 and stores the resonant electromagnetic energy. A transmission line substrate 14 is placed under the support 13 to input and output a high frequency signal. The dielectric 12 is adhesively fixed to the support 13 by means of the same material as that of the support 13. The support 13 uses an adhesive high polymer material that has a low relative dielectric constant so as not to significantly affect the peripheral electromagnetic fields of the dielectric 12. In other words, it's desirable to use a high polymer material of a low dielectric constant that is polymerized by a monomer composition containing fumarate diester.

Title: Coaxial dielectric resonator
Inventor: TANEMURA TAKESHI
IPC: H01F27/00
Filed: 1989-02-27
Abstract: PURPOSE:To increase the plating density and strength, to decrease the dispersion of no load Q and to obtain small sized resonator with excellent electric characteristic by forming the inner diameter of a through-cavity to be tapered and applying plating to other parts than the ends with a smaller inner diameter. CONSTITUTION:A resonator main body 1 provided with a through-cavity 2 is processed and the cavity 2 is tapered. Then an end 3 having a smaller diameter is formed to be an open end and copper, silver or gold plating is applied to other parts than the end 3. Thus, the cavity 2 is tapered to make the size of the main body 1 small, and even when the inner diameter of the cavity 2 is decreased, the flowing of plating liquid is not hindered and the plating thickness is applied without dispersion. Thus, the plating density and strength is increased, the dispersion in no load Q is reduced and a small sized coaxial dielectric resonator with excellent characteristic impedance is obtained.
