Title: Still video camera with post-recording of audio or video signal
Inventor: WAKUI YOSHIO
IPC: H04N5/77
Filed: 1990-06-20
Abstract: Sound and picture signals are recorded onto respective first and second tracks of a recording medium (eg magnetic disc 48) together with first and second code signals. Audio or video signals, to be associated with a particular video or audio signal, may, later on, be recorded onto an appropriate second or first track. In order to avoid accidental erasure of an already recorded track, such post-recording is permitted only when no code signal is already present on the track to be used. <IMAGE>

Title: Vacuum switch
Inventor: SCHELS WILHELM
IPC: H01H33/664
Filed: 1991-02-01
Abstract: A vacuum switch has two similar, mutually opposed switch contacts each of which is provided with a pot-shaped winding body (5) with an annular contact element (10) mounted on the open end face of the body (5). The winding body (5) is traversed, in order to form winding conductors, by a number of slits (6) which are inclined in relation to the axis of a contact stud carrying the contact and which are distributed symmetrically over the periphery. The slits (6) which may be four in number are inclined at an angle of 60 DEG  to 75 DEG  in relation to the axis of the contact studs and in a region between the contact element (10) and the base of the pot-shaped body (5), extend over an angle of rotation of not more than 60 DEG  to 90 DEG . The annular contact (10) is defined by a number of sectors, one for each winding conductor. Each contact sector (10) has at least one incision (11) extending in the radial direction from the inside towards the outside. A supporting ring is positioned contiguous to the internal diameter of the wall of the body (5). The radial wall thickness of a winding conductor is equal to about 10% of the external diameter of the body (5). <IMAGE>
Patent GB-2244371-A (GB)
Title: Plasma processing apparatus
Inventor: OHIWA KIYOSHI
IPC: H01J37/32
Filed: 1991-03-28
Abstract: A plasma processing apparatus comprises a plasma generation chamber 3 into which is introduced a gas for generating plasma by the resonance effect between microwaves introduced through window 2 and a magnetic field produced by a first excitation solenoid 6. A second excitation solenoid 14 whose oppositely directed magnetic field interacts with the field produced by the first solenoid 6 produces a cusp magnetic field. Fig 9 (not shown), in the vicinity of a substrate 11 placed in chamber 9. A power source 15 applies rf power to the substrate 11 which causes the substrate to have a negative potential with respect to the plasma. The cusp magnetic field causes the electrons in the plasma to suddenly change direction and directs them towards the peripheral walls of chamber 9. This leads to a more even distribution of ions on the surface of the substrate, as these are less spread by the cusp field than the electrons. In semiconductor production for forming a thin film by CVD, the combination of cusp magnetic field and rf bias at the substrate gives improved film quality and distribution at higher growth rates. Alternatively, Fig 14 (not shown), the second solenoid 14 may be positioned level with the substrate holder 10. <IMAGE>

Title: Monitoring temperature of array of metal-refining electrolytic cells
Inventor: SALISBURY RICHARD
IPC: G01J5/00
Filed: 1991-04-04
Abstract: An electrolytic cell monitoring system comprises an infra-red line scanner (11) which moves over an array of electrolytic coils (12) along a crane track (13). Each of the cells (17) in the array (12) has an identification tag (18) which contains data identifying its position within the array (12). The line scanner (11) moves over the array (12) and detects the temperature of each cell and transmits a digital signal indicative thereof to a remote computer (14) via a radio link (16) along with information relating to the position of the cell (17) in the array (12). An output is produced at the remote computer which indicates for example the temperature and location of each cell (17) which has a temperature greater than a predetermined limit. <IMAGE>

Title: Electric noise absorber device
Inventor: MATSUI KAZUHIRO
IPC: H01F17/06
Filed: 1991-04-10
Abstract: An electric noise absorber comprises longitudinally divided pieces (203, 206) of magnetic substance e.g. ferrite shaped to surround the periphery of an electric cable (256) when closed in a casing (205). Magnetic fluid is applied to at least one of the abutting planes of the ferrite pieces for securely contacting the abutting planes with each other. Even if the planes are rough and/or not exactly parallel, the magnetic fluid allows the ferrite pieces to be closed with no gaps between them. Consequently, the ferrite pieces (203, 206) keep substantially as low impedance as that of a non-divided ferrite piece. The fluid may be a colloidal dispersion of ferromagnetic grains in water or oil. The ferrite pieces may also be cylindrical or rectangular in section. <IMAGE>

Filed: 1995-02-20
Abstract: A bead piece aggregate which includes a plurality of columns of thin-film magnetic bead elements is cut from a wafer which is provided with a plurality of thin-film magnetic head elements arrayed in a lattice-like pattern on a base body. The thin-film magnetic head elements in the columns included in the head piece aggregate thus cut out have the same directionality on a given surface.

Next, the uppermost column of the plurality of columns included in the head piece aggregate is cut away from the others. Deviation in throat height caused by bow and bend of the head piece aggregate can, thereby, be prevented. <IMAGE>
