Title: Method and device for optical recording/reproducing and recording medium
Inventor: TANAKA SHINICHI
IPC: G11B7/005
Filed: 1990-07-13
Abstract: PURPOSE:To enable multivalued recording and to increase the recording density without losing the noise capacity by recording information by using both states of presence/absence of marks and displacement of marks in transverse direction to the traveling direction of the track. CONSTITUTION:Multivalued recording is performed by providing marks or no mark for the information and by shifting marks in transverse direction of pits, namely, in the perpendicular direction to the traveling direction of the track. In this case, it is not required to decrease the recording density so as to increase the length of the shortest pit. For example, when a pit is shifted in the transverse direction by a small amt. about 1/15 of the track period, S/N of the signals obtained from the variation of light coming back to the objective lens hardly changes. Thereby, three-valued recording can be substantially performed with using the state whether marks are provided or not and using displacement of marks in the right and left directions. Thereby, the recording density is substantially increased by 1.5 time compared to the conventional recording using binary recording state whether pit is provided or not.

Title: Film rewinding automatic stop device
Inventor: AKAHA SABUROU
IPC: G03B17/42
Filed: 1980-12-27
Abstract: PURPOSE:To simplify a switching mechanism, and to prevent a malfunction, by detecting a decrease of a load put on the rewinding shaft when rewinding has ended, in a film winding and rewinding mechanism driven by a motor. CONSTITUTION:When winding, a rotation of a motor drives a sprocket shaft 100 and a spool through a gear train, a clutch 110, etc. Also, the rotation is transmitted to gears G4-G10, but a rewinding clutch lever 303 is turned counterclockwise by a rewinding operation lever 400, and the rotation is not transmitted to gears G14, G15. When the operation lever 400 is moved to the left against a spring 405, an inclined surface 401 lifts the sprocket shaft, cuts off the winding system, also allows the rewinding clutch lever 303 to turn clockwise, and connects the rewinding system. Since a part of rotating force of the gear becomes turning force of the clutch lever by a load of a film, it is obstructed that the operation lever is returned to the right until rewinding ends.

Filed: 1987-07-27
Abstract: PURPOSE:To perform the change-over of modes of cooling and heating in an outdoor unit by means of time division, by providing an indoor unit mode recognition division recognizing an indoor side operation mode within an outdoor unit control division and providing mode recognition division making communications with the indoor unit mode recognition division of an outdoor unit side within an indoor machine side control division. CONSTITUTION:An indoor unit mode recognition division 13 recognizes cooling and heating modes when, for example, an indoor unit 11 issues the instruction of cooling operation while an indoor unit 12 issues the instruction of heating operation, and if the mode of an outdoor unit 10 is first fixed to the cooling by the cooling instruction issued from the indoor unit 11, the cooling operation is carried out between the outdoor unit 10 and the indoor unit 11. Thereafter, when a room becomes cold and a thermostat of a control division 14 of the indoor unit 11 is turned off, an outdoor control division 9 which receives an off-signal fixes the mode of the outdoor unit 10 to the heating based on the instruction of the heating operation, which has already been transmitted. The outdoor unit 10 whose mode has been changed over to the heating carries out the heating operation with the indoor unit 12 as the instruction of the heating operation has already been issued. The change-over in the subsequent steps is performed in the same manner according to time division, and both the indoor unit 11 which expects the cooling and the indoor unit 12 which expects the heating can be operated alternatingly.

Title: Thermal recorder using ink ribbon
Inventor: MACHIDA TOSHIBUMI
IPC: B41J31/00
Filed: 1988-07-27
Abstract: PURPOSE:To simplify structure of the recorder by enabling a clearance between recording paper and an ink ribbon to exist by a method wherein an ink wax layer of the ink ribbon is composed of ink wax mixed with magnetic powder, and a magnetic field is applied from a heating material normally to a plane of the recording paper. CONSTITUTION:Magnetic powder 44 in melted ink wax is accelerated with a magnetic field F, is separated from a base film 41 as ink wax 8d to be attracted, and is moved toward a surface of recording paper 3 by attraction. Ink waxes 8e, 8f fixed to the magnetic powder 44 are also moved following this attracting motion and are stuck to the surface of the recording paper 3. Therefore, even though there is a clearance between an ink ribbon 40 and the recording paper 3, recording on the recording paper 3 is performed without any hindrance. Since a magnetic field of a specific intensity is preferably formed in a specific direction at a specific position, the magnetic field F can be easily formed. Since the clearance can be formed between the ink ribbon and the recording paper, structure of the title recorder becomes wholly simple.
