Title: Magnetic recording medium
Inventor: YANAI AKIO
IPC: G11B5/65
Filed: 1981-02-24
Abstract: PURPOSE:To improve the electromagnetic conversion characteristic, the durability, etc., by vapor-depositing a magnetic metal to a base material, which moves in one direction, while changing continuously the angle of incidence from a high value to a low value to form the first magnetic film and vapor-depositing the magnetic metal to the base material, which moves in the opposite direction, while changing the angle of incidence from a low value to a high value. CONSTITUTION:While a base material B such as a polyester film is moved clockwise by a cooling can 22, the vapor of a magnetic metal from a vaporization source 21 is deposited onto the surface of the base material B continuously from a high angle of incidence to a low angle of incidence to the normal of the film, thus forming the first magnetic layer 1. Next, while the film B is moved counterclockwise, the vapor of the magnetic metal is deposited onto the layer 1 continuously from a low angle of incidence to a high angle of incidence, thus forming the second magnetic layer 2. Curves and inclined patterns of crystal columns of magnetic layers 1 and 2 become as shown in 11 and 12 in figure. Thus, a magnetic tape superior in adhesive strength between the base material B and magnetic layers 1 and 2, durability, reproduced output, etc. is obtained.

Title: Cordless telephone set
Inventor: KUMAGAI HIROSHI
IPC: H04W84/10
Filed: 1992-01-17
Abstract: PURPOSE:To speed up the time of starting speaking by providing a means for sending and stopping ring back tones to each base station and sending and stopping ring back tones at the incoming base station after setting a channel first in the case of an outgoing request. CONSTITUTION:When receiving an outgoing request command, a CPU 5 sends an incoming command through a control line 11 to a base station 6 being the incoming destination. The base station 6 receiving the command sends an incoming signal to a portable station 7, sends simultaneously a ring back tone (RBT) by itself and sends the RBT through set channels 12 and 13 to a base station 2. The portable station 7 receiving the incoming instruction from the base station 6 rings an incoming call. The base station 6 stops the ringing and the outgoing of the RBT at the same time. The speaking between a portable station 1 and the portable station 7 is enabled with the use of the set channels.

Title: Extruding method for thermoplastic resin
Inventor: NODA HIROSHI
IPC: B29C48/92
Filed: 1980-03-04
Abstract: PURPOSE:To produce films with lesser scattering in thickness with the extruded amount of resins stabilized, by maintaning number of gear pump at an identical temperature and maintaining the pulsed phase shift angle of the melted resins pressure by the cogs of each gear pump at 360 deg./n. CONSTITUTION:Melted resins are extruded from an extruding machine 1 and led into a metallic block 3 through a lead tube 2. A fixed amount of resins in the (n) number of gear pumps 4, 4' maintained at the same temperature are re-mergered by driving means 5, 5' and poured to a lead pipe 6. At the time the gear pumps are driven so that the pulsed phase shift angle of the metled resins pressure caused by the cogs of each gear pump may be 360 deg./n. The cogs cause pulses to the melted resin presure on pouring, but because these are driven at a specific phase shift, overlapping of pulses can be prevented, resulting in prevention of scattering in thickness. And because each gear pump is maintained at the same temperature, scattering in thickness to be caused by viscoity difference can also be prevented.

After that, by repeating a counter updating operation synchronizing with a clock supplied from a gate 16, the content of a regulated display area is displayed on a CRT12. The control part 113, after that, makes unnecessary the access for a display as long as no change in the display area is generated, and can devote itself in the rewrite of the memory. It is a time only when the control part 113 is not able to access to a two-port memory 101, when the one line is transferred internally from an array 105 to the register 107. The above state is generated at a time when the overflow of a row counter 121 is generated, and it can be decided by observing a signal OVF.
