Title: Disk device
Inventor: KAWASAKI TETSUJI
IPC: G11B17/043
Filed: 1990-05-11
Abstract: PURPOSE:To stabilize the inserting and ejecting operations of a disk cartridge by preventing the motion of a connecting part with a stopper in accordance with the axial position of a motor at the time of inserting the cartridge and then allowing the motion of the connecting part at the time of ejecting the cartridge respectively. CONSTITUTION:When a cartridge 8 is inserted, the motion of a connecting part of a plate spring 18 is prevented by a stopper 20 according to the axial position of a motor 12. Thus a positioning member is strongly pressed to the side face of the cartridge 8 by the spring 18. Then the cartridge 8 is surely held and positioned until the start of the following loading operation against the spring energization of a holder 9. When the cartridge 8 is ejected, the action of the coupling part of the spring 18 is allowed by the stopper 20 according to the axial position of the motor 12. Thus the positioning member is weakly pressed to the side face of the cartridge 8. Then the cartridge 8 is surely ejected by the spring energization of the holder 9. As a result, the inserting and ejecting operations of the cartridge 8 are stabilized.

Filed: 1984-06-14
Abstract: PURPOSE:To regulate the amplitude of a current flowed to a pulse motor with low power loss by driving phases by the AND output of a drive pulse and a high frequency pulse synchronized with the drive pulse. CONSTITUTION:A monostable multivibrator 20 starts operating an edge when a pulse signal F0 applied to the multivibrator 20 rises from low level to high level, and the output pulse width varies by a variable resistor VR. An AND circuit 30 produces an output only when the signal F0 and input level of motor drive signal FA - inversion signal FB coincide. An FET40 receives its output to drive a motor as a switching element. When the resistor VR is varied to increase the pulse width of a signal f0, an OFF time becomes short, a motor current increases, and when the pulse width of a signal f0 becomes short, a current iL becomes low.

Title: Open collector output signal connecting circuit
Inventor: FUSE MICHIHIRO
IPC: G06F3/00
Filed: 1990-05-15
Abstract: PURPOSE:To prevent an erroneous sampling and the oscillation on a receiver side by providing plural transmission lines, sending out an open collector output signal to each transmission line by the timing being different timewise, respectively, and executing the sampling by avoiding the part of a transient state on the receiver side. CONSTITUTION:An open collector output signal is sent out to plural transmission lines A, B by shifting the timing timewise little by little, respectively. Subsequently, on a receiver 30 side, output signals of each transmission line A, B are subjected to sampling in the prescribed sequence set in advance, so that at the time of this sampling, the open collector output signal avoids the part of a transient state passing through the vicinity of a threshold. The same open collector output signal is shifted timewise and outputted from each transmission line A, B, therefore, in the case a signal of a transient state is outputted from one transmission line A, etc., a signal whose high potential or low potential is exact is obtained from the other transmission line B. In such a way, an erroneous sampling and the oscillation on the receiver 30 side can be prevented.

Title: Optical modulation substance and application, production thereof
Inventor: KOMATSU ERI
IPC: C08K9/10
Filed: 1987-05-20
Abstract: PURPOSE:To obtain the title substance capable of optical modulation by dispersing droplets of a liquid crystal into a cured substance composed of a thermosetting one-pack epoxide resin. CONSTITUTION:The title substance is formed by interposing the cured substance 1 which is composed of the thermosetting one-pack epoxide resin and is dispersed the droplets of the liquid crystal 2, between sheets 5 which are composed of a glass and a plastics, etc., and mounted two sheets of the electrically transparent conductive film 4 thereon respectively. The cured substance is reversibly changed between an opaque and a transparent states by combining a temp. and an electric field, thereby holding the opaque or the transparent state in a room temp. and a nonelectric field state. As the upper limit of the clearing point of a conventional liquid crystal is 80-130 deg.C, the thermosetting one-pack epoxy resin is preferably cured at a temp. (especially and preferably 40-200 deg.C) lower than the clearing point of the liquid crystal, and for this purpose, a latent curing agent is incorporated in said resin. Thus, the resin becomes transparent at the time of impressing the electric field, and opaque at the time of un- impressing the electric field.
