IPC: G11B5/008
Filed: 1990-08-30
Abstract: PURPOSE:To perform the endless recording/reproducing of a magnetic tape by dividing the recording/reproducing part of the magnetic tape into two parts in the vertical direction, switching the normal/reverse rotating direction of a rotary cylinder fitting in the normal/reverse feed direction of the magnetic tape, and furthermore, switching a magnetic head so as to locate the starting position of recording/reproducing in the center part of the magnetic tape. CONSTITUTION:When the recording/reproducing of the magnetic tape 4 is performed to the end of it, the feed direction of the magnetic tape and the rotating direction of the rotary cylinder 2 are automatically reversed, and also, a recording/reproducing interval 7R is switched. Therefore, the recording/reproducing part of the magnetic tape 4 is divided into the two parts in the up-and-down direction, and the recording/ reproducing can be continued without stopping the magnetic tape. In such a case, since the recording/reproducing can be performed at a magnetic tape take-up side where high tape tension of a rotary head assembly is always obtained by setting the rotating direction of the rotary cylinder 2 reversely, satisfactory abutting of the rotary magnetic head with the magnetic tape can be obtained. In such a way, a magnetic recording and reproducing device in which the endless recording and reproduction of the magnetic tape can be performed, and also, with superior linearity of recording track can be obtained.

Title: Planar rectiner
Inventor: TESHIROGI TAMOTSU
IPC: H01Q23/00
Filed: 1990-09-01
Abstract: PURPOSE:To constitute a rectifying circuit section on one substrate by connecting a rectifying diode between coupling microstrip lines. CONSTITUTION:An element antenna 3 is a unidirectional microstrip antenna and in basic mode, equi-amplitude reverse phases appear at two symmetric power supply points 4-a, 4-b on the antenna element 3. Radio waves received at different power receiving points are fed on microstrip lines 13-a, 13-b having same electrical length to a rectifying circuit section. Since two inputs on a coupling microstrip line 14 have equi-amplitude reverse phases, odd mode transmission takes place. Consequently, a transmission mode in which a field is formed in the direction of the thickness of a dielectric 1 is converted on the microstrip lines of 13-a, 13-b into a transmission mode in which the field concentrates between two coupling microstrip lines. Consequently, a diode 8 can be connected between the coupling microstrip lines 14 resulting in a planar rectiner.

Abstract: PURPOSE:To prevent firing due to degradation of MOV by connecting a metal oxide varister(MOV) in series with a bimetal switch circuit which is operated by the heat of MOV. CONSTITUTION:A switch B is normally turned ON and a MOV 1 is connected with a power source 11.
