Patent JP-S598158-A (JP)
Title: Rotary head assembly
Inventor: IMANISHI KIYOKAZU
IPC: G11B5/52
Filed: 1982-07-06
Abstract: PURPOSE:To record and reproduce high-quality pictures, by discharging air from a spiral groove part to the outside through the space between end faces facing each other of a rotary cylinder and a fixed cylinder. CONSTITUTION:An overlap cylinder inside face 3a and an overlap cylinder outside face 2a which are formed in the upper part of a fixed cylinder 3 overlap each other through a space delta2 to form a center cylinder face. A spiral groove 21 is formed on the surface of the overlap cylinder outside face 2a. An upward air current is generated by the spiral groove 21 when a rotary cylinder 2 is rotated, and air discharged o the outside from the space between the rotary cylinder and the fixed cylinder gives a floating force to a magnetic tape. Uniform air films are formed for the magnetic tape on outside circumferential faces of the rotary cylinder 2 and the fixed cylinder 3, and the sliding contact between the magnetic tape and a rotary head assembly is avoided to realize smooth tape running.

Title: Water-dispersed polybutadiene-modified epoxy resin composition
Inventor: YAMASE YUKIO
IPC: C08G59/40
Filed: 1981-07-28
Abstract: PURPOSE:To provide an aq. dispersion of a resin, which has an excellent long- term stability and gives cured articles having good peeling strength, flexibility and impact strength, consisting of a polybutadiene-modified epoxy resin, water and a surfactant in a specified ratio. CONSTITUTION:An aq. dispersion of a resin consists of a polybutadiene-modified epoxy resin/water of 90/10-1/99, and water/surfactant of 100/15-100/0, said modified epoxy resin being obtd. by reacting a carboxyl group-contg. polybutadiene homopolymer and/or copolymer (A) with an epxoy resin (B) in an amount of 1.8-30 equivalents of epoxy groups per equivalent of the carboxyl group in component A with heating. When the amount of epoxy group is less than 1.8 equivalents, the viscosity is remarkably increased.

Title: Card with voice storing function
Inventor: MIYAZAKI HAJIME
IPC: B42D15/02
Filed: 1988-05-13
Abstract: PURPOSE:To prevent the mistaken input of a switch while a card is carried by providing a photoelectric conversion element executing the prohibition and the release of the recording and reproduction switch input with the aid of opening or shutting the card and prohibiting the recording and reproduction switch input in the state that the card is shut. CONSTITUTION:A phototransistor (a phototra) 20 is used as the locking function of the switch. That means, when the card is shut (in the state that the card 16 and the card 21 are folded by setting a fold 22 as a border), the phototra 20 becomes an OFF state because it is not exposed to light and the recording and reproduction button is made to be a locked state by detecting that OFF state with the aid of an IC. Besides, when the card is opened, the phototra 20 becomes an ON state because it is exposed to light and the recording and the reproduction button is made to be an unlock state by detecting that ON state. Thus the mistaken input of the switch while the card is carried can be prevented.
