Title: Bus acquiring system
Inventor: UCHIYAMA YUKIO
IPC: G06F13/362
Filed: 1987-06-02
Abstract: PURPOSE:To effectively process an emergency bus request of each device by using properly two types of signal lines which connect a bus controller to each device as the bus request signal lines. CONSTITUTION:The signals lines 5, 6; 7, 8; 9, 10 are used between devices 1-3 and a bus controller for emergency bus requests. When the line 10 of the device 3 is set at '0', the output of an inverter 30 of a bus controller 4 is set at '1' and a NOR gate 24 cuts off a normal bus request given from the device 2. At the same time, the output of a NOR gate 28 is also set at '0' based on the output '1' of an OR gate 32. The input of a priority circuit 11 is set at '0' together with the output of an inverter 20 and no acknowledge signal is sent from the circuit 11. While, a priority deciding circuit 12 receives an emergency bus request from the device 3 via the inverter 30 and sends back a bus acknowledge signal to the device 3 via an inverter 29 and the line 9. Thus a bus is acquired by the device 3.

Filed: 1988-06-07
Abstract: PURPOSE:To improve electromagnetic conversion characteristics in a short wavelength region by forming a perpendicularly magnetized Co-O film in such a manner that the axis of easy magnetization thereof has a prescribed inclination with the film plane. CONSTITUTION:The perpendicularly magnetized Co-O film is so formed that the the coercive force curve at 0 deg.<=theta<=90 deg. and the coercive force curve at -90 deg.<=theta<=0 deg. are asymmetrical when the coercive force of said film is measured by changing the angle theta of inclination of the direction of the magnetic field impressed in the normal direction of the perpendicularly magnetized film. This perpendicularly magnetized Co-O film is formed by adjusting the position of a shielding plate 10 in, for example, an electron beam vapor deposition device in such a manner that the vapor generated from a metal evaporating source falls onto a nonmagnetic base 9 at a certain incident angle. The coercive force is improved in this way and the reproduced output in the short wavelength region is improved.

Title: Transmission mechanism for camera
Inventor: TANAKA HARUMI
IPC: G03B17/00
Filed: 1986-06-14
Abstract: PURPOSE:To simply draw out a film from a spool without applying unnatural force to the film when the film is to be taken out on the way of use by forming a spool rotation allowing mechanism for allowing the spool to rotate in a film rewinding direction when a back cover is opened. CONSTITUTION:The spool rotation allowing mechanism SR for allowing the film winding spool 4 to rotate in the film rewinding direction when the back cover 9 is opened is provided. Then the back cover 9 is opened, a spool board 7 is restored to a film winding position, but the bending part 8b of a locking tool 8 is not abutted upon the back cover 9 and the exciting force of the locking tool 8 is not applied to the projection 7a of the spool board 7. Thereby force larger than the exciting force of a spring 10 is applied to the spool board 7 and the board 7 is kept at a freely rotatable state. Consequently, the film can be drawn out from the camera without executing specific operation only by opening the back cover 9 and drawing out the film.
