Title: Confocal scanning type microscope
Inventor: IWASAKI OSAMU
IPC: G02B26/10
Filed: 1990-04-10
Abstract: PURPOSE:To always reproduce a microscope image of a high contrast and a good quality by monitoring a focused state to a sample of an illuminating light by a focus monitor means, and outputting an output signal of a photodetector for carrying a microscope image to an image reproducing device side, only when the illuminating light is focused on the sample. CONSTITUTION:When an illuminating light is focused on the surface of a sample, a reflected light 11'' forms an image of a roughly regular circle on a quadrisected photodetector 53. Accordingly, in this case, outputs of each photodetector 53a - 53d becomes roughly equal, and an output Sd of a differential amplifier 56 becomes about zero. The output Sd of the differential amplifier 56 is inputted to a window comparator 81, compared with an output of a reference voltage setting circuit 80, and when it is within a range of outputs TH1, TH2, an output of the window comparator 81 becomes an H level, and when it is outside of the range, its output becomes an L level. Also, only when it is in an H level, signals SB, SG and SR are outputted, and when it is in an L level, the signals SB, SG and SR are not outputted. In such a way, a microscope image of a high contrast is always obtained.

Title: Magnetic recording medium
Inventor: WAKAMATSU HIROAKI
IPC: G11B5/64
Filed: 1984-05-11
Abstract: PURPOSE:To average S/N over the entire surface by providing a magnetic layer which consists essentially of gamma-Fe2O3, is incorporated therein with Cu, Ti and Co, contg. Cu in a specific concn. range and having the concn. of Cu increasing continuously from the outside circumferential part of the disk toward the inside circumferential part on a non- magnetic disk substrate. CONSTITUTION:The magnetic layer which consists essentially of gamma-Fe2O3 and is incorporated with Cu in order to decrease noise, Ti in order to increase the temp. margin in the stage of forming a film and Co in order to increase coercive force is formed by a sputtering method on the disk-shaped substrate, more particularly Al, glass or ceramic substrate. If the amt. of the Cu to be added is increased in this stage, the crystal grain size of gamma-Fe2O3 decreases and the S/N ratio increases but the grain boundary is made less stronger and softer than the crystal part and is thus made vulnerable to damage by a magnetic head. The outside circumference of the disk is made particularly susceptible to a damage. Cu is incorporated into the magnetic layer at 0.1-5at% over the entire part thereof and is so incorporated that the concn. thereof decreases from the outside circumferential part toward the inside circumferential part in order to prevent the above-mentioned damage. The S/N over the entire surface of the disk is thus averaged and the noise is reduced overall. Durability is improved as well.

Title: Traveling object communicating method
Inventor: HASHIMOTO TADAHIKO
IPC: H04B7/26
Filed: 1983-06-01
Abstract: PURPOSE:To constitute so that a communication can be executed at random without generating a radio interference between plural vehicular stations and a ground station by using one radio wave in one communication area, by detecting a generation of a radio interference by the ground station, selecting efficiently a vehicular station having a request of communication, and giving a right of communication to its vehicular station. CONSTITUTION:C shows a generation of a radio interference. A car # of a traveling object 1 and a car # of a traveling object 2 are denoted as -001 and - 100, respectively. A ground station side receives simultaneously radio waves from two traveling objects, therefore, a carrier detection time measuring part in the ground station detects a carrier Tw, and decides that a transmission from a vehicular station exists. Also, when an error is generated, it is judged to be a radio interference, and subsequently, a vehicular station which is allowed to execute a transmission is limited. As a result, the vehicular station which is allowed to execute a transmission is limited to 1/2 of all the vehicular stations. In this state, if the radio interference is generated again, furthermore, the vehicular station which is allowed to execute a transmission is limited to 1/2. This method is repeated. With respect to two traveling objects, the lowest bit of the car # is limited to ''1'', and a right of transmission is given to the vehicular station in which the lowest bit of the car # is ''1''. In this example, the traveling object 1 is ''1'', and the traveling object 2 is ''0'', therefore, the traveling object 1 has a right of transmission, and executes a communication.

Title: Printing material removing device
Inventor: YOSHIE NAOKI
IPC: G03G21/00
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To prevent printing material from being transferred from a peeling member to recorded material again by heating the printing material on the peeling member after peeling the printing material from the recorded material. SOLUTION: The recorded material 8 separated from a peeling belt 2 is bent in a circular-arc state against the surface layer of the peeling member by a separation pawl 3 and a driven roller 6. As a result, shearing force is generated between the surface of the material 8 and the toner 7, so that the toner 7 is surely peeled. The toner 7 on the material 8 is left on the surface layer of the peeling member in a state where it is fused and solidified there, and peeled from the material 8 and transferred to the surface layer of the peeling member. The toner 7 transferred to the surface layer of the peeling member is moved in a direction shown by an arrow (d) together with the belt 2. When the toner 7 on the surface layer of the peeling member reaches a counter part to a heating roller 4, it is heated by the roller 4.  As a result, the cohesive force among the toners 7 becomes strong and the adhesive force between the toner 7 and the surface layer of the peeling member is increased, so that the toner is prevented from being transferred again.

Title: Ink jet recording device
Inventor: FUKUSHIMA TORU
IPC: B41J13/00
Filed: 1990-04-11
Abstract: PURPOSE:To obtain an ink jet recording device capable of recording data stably without print contamination by providing a sequential feed device which sequentially feeds recording media held by a multi-stage holding device. CONSTITUTION:A recording sheet 11 is transported after completion of data recording and then is stacked on a stacker as the first holding device after discharge. However, the first stacker 2 is positioned with the same clearance as is the second stacker 3, so that the recording sheet can be adjusted to an appropriate width L by widthwise adjustment of a sprocket 5. In addition, the first stacker 2 can be opened over a broader clearance than the width of the sheet, while the second stacker 3 is closed in the center so that its sections are stacked one over the other. Subsequently, the recording sheet 11 on the first stacker 2 falls onto the second stacker 3 by its own weight and the first stacker 2 is restored to its original state. Thus another recording sheet 12 can be placed on the first stacker 2. After this process, if the second stacker 3 is opened wider than the width of the sheet, the sheet 11 is stacked on the third stacker 4 with the sheet 12 left as it is, as the first stacker 2 remains closed. In this manner, the sheets can be placed over the other without print contamination.
