Title: Magnetic transfering and recording system
Inventor: SAWAZAKI KENICHI
IPC: G11B5/86
Filed: 1979-09-13
Abstract: PURPOSE: To make it possible to transfer a high-density recording medium easily and exactly, by using a ferromagnetic material as its magnetic material, recording a signal in it in the concave-convex shape, and furthermore using a master magnetic recording medium which is made by magnetizing the recording surface by a constant magnetic pole.  
     CONSTITUTION: A master magnetic recording medium 1 has a magnetic layer 2 consisting of a ferromagnetic material, and a signal is recorded in the magnetic layer 2 in the concavo-convex shape. This recording medium 1 is made to run between the magnets of S and N poles 21, 22, and it is magnetized in the constant direction. The magnetic surface 4 of the magnetic recording medium to be transferred 3 is made to closely adhere face to face to the magnetic surface of the master recording medium 1. And AC electromagnets 5, 6 are installed with mediums 1, 3 sandwiched, and the AC magnetic field is added in the direction of thickness of the recording medium 1, 3 by making an AC current flow from the AC power supply 7. As a result, the recording medium to be transferred 3 is magnetized by varied strength depending upon the concavo-convex part of the signal of the master recording medium 1. Accordingly, the high-density recording medium can be transferred easily and exactly.

Title: Image forming device
Inventor: UCHIDA SHUNJI
IPC: G03D11/00
Filed: 1986-05-21
Abstract: PURPOSE:To discharge a dried photosensitive material with its exposed surface upward by providing a means that inverts and exposes the surface of the photosensitive material through an exposure barrel in a processing solution tank. CONSTITUTION:The photosensitive material conveyed in the 1st developer tank points its emulsion surface toward the exposure window of the inversion and exposure means 42, and light beams from a light source 424 invert and expose the photosensitive material through the window 421. Since the outer surface of the transparent plate 426 of the window has one horizontal projecting part 427, the photosensitive material touches only the projecting part. Soil caused by emulsion concentrates on the projecting part, and luminous energy projecting the photosensitive material is always uniform. As the photosensitive material passing through plural processing tanks is discharged with its photosensitive surface upward, the surface is never rubbed by a paper discharge tray and no printout is damaged.

Filed: 1990-05-07
Abstract: PURPOSE:To inform users of not only the portion but also the exact time at which abnormality has occurred by correcting the time of a timer means correspondingly to a time announced by radio broadcasting, and storing the time together with abnormality information. CONSTITUTION:An electrical equipment control device is basically comprised of a timer block A and a detector block B.

Title: Clock attached with service interruption displaying feature
Inventor: NAKADA ETSUO
IPC: G04C9/00
Filed: 1979-09-14
Abstract: PURPOSE: To economize electric power by a method wherein both the service interruption display and the service interruption can be performed simultaneously and further, no clock displaying the wrong time is allowed to operate by installing a contact device, a service interruption correction lever, a service interruption display panel and an electromagnet.  
     CONSTITUTION: When electric power stops to run because of the service interruption, the contact of the service interruption correction lever 1 due to the electromagnet 24 is released and the service interruption correction lever 16 returns to the position where the force is not applied by the elasticity of its elastic part 16a. As a result, the contact of the contact 20a with the contact plate 20b is also released. Further, since the service interruption correction lever 16 restores the position where no force is applied, the position of the service interruption display panel 18 corresponding to the service interruption display window alters thus, the display panel at the lower side 18b of the service interruption display panel 18 can be seen with naked eyes through the service interruption display window. Further, even when the service interruption is over and power flows from the power source 30, both the contact 20a and the contact panel 20b are in the released state and the clock circuit 34 is not closed. Therefore, as long as the contact system composed of the contact 20a and the contact plate 20b is not closed by pushing down the service interruption correction lever 16 by means of external force, the clock does not operate.
