Publication number: 20030210892Abstract: A phase standard position signal generator generates a phase standard position signal of a predetermined period indicating the phase standard position of an image signal of 24 frames/second format, for recordation into a recording reproducing medium. In reproducing from the recording reproducing medium, a phase standard position sensor senses the phase standard position signal. A counter performs frequency quintuplication of the phase standard position signal and counts the period of the frequency-quintupled signal. A time code reader reads a 24 Hz time code value from the recording reproducing medium. A time code generator calculates a 30 Hz time code with the use of the counted value given by the counter and the 24 Hz time code value. Thus, the time code of 24 Hz period is converted into the 30 Hz time code with high precision even in variable-speed reproduction.Type: ApplicationFiled: March 24, 2003Publication date: November 13, 2003Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Ikuhisa Yoshida, Hisataka Ueda

Publication number: 20030208875Abstract: A vacuum cleaner has a suction air inlet disposed in front of an electric blower and a dust chamber detachably installed to the rear of the electric blower. The vacuum cleaner further embodies a swivel caster and wheels for facilitating transportability thereof, wherein the swivel caster is provided in front of the electric blower. By not having the dust chamber above the swivel caster, regardless of the amount of dust accumulated in the dust chamber, the load that is distributed on the swivel caster stays substantially unchanged, thereby enhancing durability of the swivel caster. Furthermore, in such configuration loading and unloading of the dust chamber can be carried out without being interfered with a hose due to the placement of the suction air outlet connected with the hose and the dust chamber on opposite ends of the vacuum cleaner.Type: ApplicationFiled: May 7, 2003Publication date: November 13, 2003Applicant: Matsushita Electric Industrial Co., Ltd.Inventors: Koichi Ito, Hiroshi Nishimura
