摘要： PURPOSE:To suppress the decrease in the amount of floating, even if the flowing angle of the air of a slider changes, by providing a recess at the lengthwise middle part of a flat part of a slider rail and giving a gradual change to the depth of recess near the flat part of the recess. CONSTITUTION:When a slider is positioned almost at the center of a magnetic disc with a swing actuator, air flows to a slide rail 2 of the slider along the lengthwise direction and a normal floating force is obtained. When the slider is positioned to a position corresponding to the start or end of the magnetic disc, air A flows from the side surface of the slider and the slider can stably be floated with the bearing action with a slope 3 and a flat part 4 and with air flow-out part of a recess 5 and a flat part 6. Further, since the depth of recess is gradually changed near the flat parts 4 and 6 of the recess 5, the pressure distribution generated to the slider rail 2 is also changed gradually.

摘要： PURPOSE:To obtain an EL panel having brightness required for practical purposes and a lone life, by forming a luminescent layer consisting of EL phosphor particles fixed within sintered titanium oxide, between two electrodes at least one of which is transparent. CONSTITUTION:On a transparent electrode 2 is formed a luminescent layer by using a mixture obtained by mixing (i) EL phosphor particles (such as ZnS type), (ii) an organic metal complex of Ti, and optionally (iii) transparent or white inorganic powder (such as barium titanate) which is harmless to component (i) and has a particle diameter smaller than that of component (i). Then, onto the layer is formed a back electrode 5 by vacuum evaporation of Al. Then, the assemblage is fired at about 450 deg.C for 40-60min to remove moisture in the luminescent layer and at the same time to decompose component (i). In this way, an EL panel having a luminescent layer 3 in which component 31 (i) and component 32 (iii) are fixed within sintered titanium oxide 33 is obtained.

摘要： PURPOSE:To reduce the rotary tonque while preventing damage to the film by employing a hollow cylinder for the film roller, supported with an gas bearing. CONSTITUTION:A film roller 2 is suported at both ends rotatively with a gas bearing 6 such as air bearing. The bearing 6 is fixed on a frame of a film conveying device so as to regulate the axial change of the roller by a ring-shaped plate provided on the side of the bearing. With such an arrangement, the roller can be rotated with a limited torque while the blowing off of gas from the bearing checks the mixing of fine dirts thereinto. Lillts change in the torque minimizes scratch on the film.

摘要： PURPOSE:To obtain an optical transmission system which includes a connection path formed as a bus and whose handleability is improved by providing an optical branch coupling means changing a transmitted optical signal to an optical signal in another band, synthesizing it with a remaining signal and outputting the synthesized. signal. CONSTITUTION:One part of the optical signal entering the input terminal 7 of the optical branch coupling element 9 of a recording and reproducing device 3 goes to an optical signal receiving part 10 and the remaining optical signal enters an image receiver 4 from and output end 8 through a transmitting body 5. A detection means 11 outputs a signal from the receiving part 10 and the detected result about the band to which the signal belongs, and an operation mode detecting means 12 outputs the detection signal of the operation mode of the device 3. In the case the signal detected by the means 11 shows a reproducing mode, a discrimination means 13 transmits a reproducing signal to a control means 19 through a reproducing circuit 18, and the means 19 changes the band of the reproducing signal in order to distinguish it from the signal from the receiving part 10 and outputs the signal to a transmitting part 20. By such constitution, the optical transmission system in which the connection path between plural equipments is formed as the bus and whose handleability is improved is obtained.

摘要： PURPOSE:To return a medium to a user without waiting the arrival of a clerk or the abnormality restoration of a connected apparatus to shorten user's wait ing time if an automatic teller machine such as a cash dispenser working on a holiday or in an unmanned shop is stopped wrer it detects the abnormality of another connected apparatus. CONSTITUTION:A program for judging (1, 3) whether a fault is caused in medium return enabled status or not when an automatic teller machine such as a cash dispenser runs down in a transaction, and when the return is possible, judging (10, 12, 13) whether the user is a card owner himself (or herself) and returning (14) the medium in the case of the owner himself (or herself) is prepared. The teller machine is also provided with a memory for storing a personal identification (ID) number checked at the time of starting the transaction and judged as a proper number in order to judge whether the user is the owner himself (or herself) or not.

摘要： PURPOSE:To provide a video optical disk system compatible with a reproducing only optical disk by recording the same recording format as the reproducing only optical disk (LD) and using a specific player part. CONSTITUTION:A recorded disk 3 is made by using an optical disk having a C/N of >=60dB and recording video software with the same address signal as the LD 15 and an NTSC direct FM recording format by a recording part 2. Then, in the player part 4, an optical head and a picture processing circuit are shared with the reproducing only disk 15, and since a reflectance of the recorded disk 3 is low, a reflectance detecting circuit is added to an LD player. By a signal of this reflectacne detecting circuit, a focus tracking circuit, an RF signal preamplifier circuit and a tilt control circuit are changed, so that the recorded disk 3 and the LD 15 can be reproduced.
