Title: Tape driving controller
Inventor: YOSHIMOTO MITSUFUMI
IPC: G11B15/48
Filed: 1987-06-30
Abstract: PURPOSE:To prevent the production of excessive tape tension due to tape end stop by applying deceleration control to the tape speed at all times from the vicinity of tape end just before the tape end independently of the tape position where the high speed traveling is started. CONSTITUTION:The tape speed is detected based on the detection period of the supply reel 1 and the take-up reel 2 at the high speed traveling of a tape 3 and the detection period of the supply reel 1 and the detection speed of the tape 3 are substituted in a calculation equation of a divider of deceleration composed of a negative linear function of the product of the rotary period of the supply reel 1 and the tape speed to calculate the deceleration divider. When the calculated deceleration divider reaches 1 or above, the speed of revolutions of the take-up reel 2 is decelerated by a ratio of the deceleration divider to be calculated and the tape speed is subjected to deceleration control according to the linear function equation. Thus, even when the high speed traveling is started from the tape position, the tape speed is started to be decelerated by the ratio of the deceleration divider when the tape reaches the vicinity of tape. Thus, the production of excessive tape tension due to the tape end stop is prevented.

Title: Device and method for decoding image signal
Inventor: OSADA ATSUSHI
IPC: H04N19/587
Filed: 1997-06-23
Abstract: PROBLEM TO BE SOLVED: To reduce distortion caused in an interpolated picture by previously synthesizing the interpolated picture and replacing one part of this synthesized interpolated picture with an input image signal as a compensated image for a block, where the distortion is considerable in the interpolated picture. SOLUTION: A reception circuit 202 reproduces an image encoded signal, motion vector signal and compensated image signal from an input bit stream signal. A frame decoder circuit 203 obtains a thinned regenerative picture by decoding the image encoded signal. While using the reproduced picture and the motion vector signal, a frame interpolation circuit 204 synthesizes the interpolation picture to be interpolated between the thinned reproduced pictures. While using the compensated image signal, a distortion compensation circuit 205 replaces one part of the interpolated picture with a compensated image. The position inside the frame to be replaced is equal to the position inside the frame where the distortion is previously discriminated considerable by a moving image encoder circuit 1, and the compensated image is extracted.  A switching circuit 206 obtains the reproduced picture from the side of (c) and the distortion compensated interpolated picture from the side of (i). Thus, the image of natural motion can be obtained from the considerably compressed signal.

Abstract: PROBLEM TO BE SOLVED: To cancel vibration noise, without receiving a restriction on the design of the arrangement of a microphone or the like by utilizing the signals of angular velocity sensors in X and Y-directions, utilizing the microphone as a vibration sensor as well, providing a delay circuit in signals from the X and Y- directions and subtracting respective signal components. SOLUTION: The signals from angular velocity sensors 1 and 1' in the X (horizontal) and Y (vertical)-directions are passed through amplifiers 4 and 4', desired vibration noise signal components are taken out in BPFs 5 and 5', and the respective signals are added in an adder 6. In this case, since a microphone (b) is arranged inside a same equipment as a lens (a), vibration is also transmitted to the microphone (b) with the delay of a time difference T. Thus, the vibration components of the lens (a) are delayed for the time difference T, similarly to the vibration delay time of the microphone (b) by the delay circuit 7, subtracted with the signals of the microphone (b) in a subtractor 8 and outputted to the amplifier 9. Microphone audio output is obtained in the stage in which the vibration noise in the amplifier 9 is not output.

Abstract: PURPOSE:To obtain an apparatus for molecular beam growth, constituted so as to feed gas molecules cracked by an electron cyclotron resonance device having the inner wall coated with Si at the tip of a nozzle to a substrate and capable of providing a high growth rate of an Si single crystal film. CONSTITUTION:The tip of an electron cyclotron resonance device 3 is sealed to introduce silane gas from a gas cell 4, entrap and heat the gas in the device 3. Thereby the silane gas is thermally decomposed in the interior of the device 3 to coat the inner wall with Si. Silane gas is then passed from a silane gas cylinder 8 through a valve 7, the gas cell 4 and device 3 into a growth chamber 1 at a high vacuum degree. In the process, microwaves are introduced into magnetic fields in the device 3 just before introduction of the silane gas into the chamber 1 to excite cyclotron motion of electrons present in the gas atmosphere and crack the silane gas into ions or radicals. The cracked silane gas is then fed to an Si substrate 2. Thereby an Si single crystal film without containing impurities can be formed on the substrate 2 at a high growth rate.
