Title: Vacuum cleaner
Inventor: CHICHII KAZUO
IPC: A47L9/00
Filed: 1990-08-30
Abstract: PURPOSE:To obtain a vacuum cleaner which can solve a trouble due to contacting between the end portions of both covers without any increase in the distance between the end portions of both covers by providing two upper covers, one of which has a shaft hole of a rotary shaft extended in the horizontal direction to be an elongated hole, and providing a taper portion on the end portion of the upper cover. CONSTITUTION:A rotary shaft 12 of a rear upper cover 11 is supported by an elongated hole 20 bored in a supporting portion 21, and a taper portion 22 is installed on the rear end portion 11b of the rear upper cover 11. Just before a front upper cover 10 is to be closed to the stopped rear upper cover 11, the force in the direction of an arrow 18 is applied to the rear upper cover 11 so that the rear upper cover 11 is moved to the right in the drawing. Accordingly, the contacting between the front upper cover 10 and the rear upper cover 11 is canceled to avoid a trouble such as a breakage of the upper cover or the like. When the rear upper cover 11 is just to be closed after it is moved to the right in the drawing, the taper portion 22 of the rear upper cover is brought into contact with the rear edge portion 14a of an attachment storing portion, so that when the rear upper cover 11 is pressed from above, the taper portion 22 is moved to the front of the cleaner main body along the rear edge portion 14a to force the rear upper cover 11 to return to the forward for the movement to the rear of the cleaner main body.

Title: Information recording method and information recording medium
Inventor: MATSUSHIMA TOSHIYUKI
IPC: G11B7/0045
Filed: 1993-09-13
Abstract: PURPOSE:To improve a contrast ratio and recording density by subjecting an alloy having a crystal phase-quasi crystal phase-amorphous phase to heating and annealing treatments by irradiating this alloy with light, thereby causing the phase transition of the alloy and changing an electron state. CONSTITUTION:The alloy which is a base metal is produced by arc melting in production of a recording medium layer. Further, the production is executed by forming the special crystal phase having positive 20-faces symmetry and its self-resemblance structure by a single roll method of rapid cooling with liquid. The discrimination of the phase transition is executed by an electron beam diffraction device and the difference in diffraction spots is discriminated by image processing. While this quasi-crystal thin film 4 has a special defect of phase defects, these defects are decreased by annealing. The contrast ratio of the recording state is increased and the recording density is improved by incorporating the quasi-crystal phase into the conventional crystal-amorphous phase transition type optical recording medium.

IPC: G06T7/20
Filed: 1987-09-14
Abstract: PURPOSE:To analyze images at a high speed by reorganizing a 2-dimensional difference image from the image signals of two continuous frames of moving image signals expressed in time series signals to record said difference image without performing time series processing and processing directly the recorded 2-dimensional difference optical signal by means of a light beam. CONSTITUTION:A difference image signal 7 is recorded 2-dimensionally in a space/light modulator 4 and the read light is projected on the modulator 4. Thus the time series signal 7 recorded in the modulator 4 is converted into a 2-dimensional difference optical image signal 12 and extracted. Furthermore, the signal 12 undergoes 2-dimensional photoelectric conversion via a 2-dimensional optical position detector 24 for detection of the centroid coordinates of a difference image. These series of actions are carried out continuously to obtain the moving direction, the moving vector, the moving speed, the motion vector, etc., of the moving image. As a result, the images are analyzed easily and at a high speed.
