Title: Control device for three-dimensional automatic warehouse
Inventor: MINAMITAKE KATSUTO
IPC: B65G1/137
Filed: 1990-02-27
Abstract: PURPOSE:To improve efficiency in a control device for an automatic warehouse equipped with a two-throw forklift by comparing the combination of parts demanded to be supplied with the combination of parts demanded to be warehoused or rewarehoused to determine a warehousing shelf, and to command a crane travel control unit to warehouse or re-warehouse the parts. CONSTITUTION:A control device 1 receives a part supply demanding signal Sro from an assembly line 5, and simultaneously stores N-times of combinations of parts demanded to be supplied in the past. Further, when a warehousing signal Sri is inputted from a warehousing position 21, and when a re- warehousing demanding signal Srr is inputted from the assembly line 5, the control device 1 compares the combination of parts demanded to be ware-housed with the parts-combinations stored in a storage means 11, checks on the presence or absence of the same part-combinations in the past, and when the above warehousing-demand existed in the past, a shelf-determining means 13 determines a shelf so that the parts are warehoused in a adjacent empty shelf, and commands a crane travel control unit 3 to warehouse the parts. By this constitution, efficiency can be improved.

Title: High frequency power amplifier
Inventor: TSUTSUI TAKAYUKI
IPC: H04B1/04
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To construct a linear amplifier and a saturable amplifier by means of a single input/output circuit by securing the different threshold and largest output power levels among plural transistors to which the amplifier of the final amplifier stage is connected in parallel, respectively. SOLUTION: The 1st and 2nd transistors Tr1 and Tr2 whose threshold levels are intentionally different from each other are placed in parallel to each other. In such a constitution, the largest output power levels of both Tr1 and Tr2 are different from each other. In an analog communication state where a saturation operation is carried out, an amplifying operation is carried out at an operating point where the gate bias is shallow. At this operating point, the bias is dominantly applied the Tr1 only and accordingly only the Tr1 is apparently turned on to expect the high efficiency by the saturation operation of the Tr1. At an operating point where the gate bias is deep, the bias is applied to both Tr1 and Tr2 and accordingly the transistor sizes are apparently increased to expect a linear operation.

Gates 10 and 19 are closed by the mark signal, and counted values of counters 11 and 21 are held in 12 and 22. In this case, the beam is deflected by one bit components in the step output of DA converter 1, and the mark signal is generated halfway. Then, a time point of the deflecting pulse when the mark signal is generated is detected by storage counted value 22, so that a high- precision mark position detection can be performed. By this constitution, the exposure speed at a mark detection time can be made high while maintain a high precision.

Title: Damping-waterless photosensitive planographic printing plate
Inventor: MAEDA YOSHIHIRO
IPC: G03C1/00
Filed: 1988-02-29
Abstract: PURPOSE:To form a damping waterless planographic printing plate which is free from scumming at the time of printing by incorporating a fluorine surfactant into a photosensitive layer. CONSTITUTION:The fluorine surfactant is incorporated into the photosensitive layer. The fluorine surfactant to be used is exemplified by, for example, perfluoroalkyl sulfonic acid or the salt thereof, etc. While heretofore the stained layer generated by the reaction effected by the material incorporated between a silicone rubber layer and the photosensitive layer degrades an ink repulsive property, the fluorine surfactant in the photosensitive layer exists locally at the boundary face with the silicone rubber layer and hardly induces the reaction at the boundary face and, therefore, the good ink repulsive property is obtd. The damping-waterless planographic printing plate which has good printing resistance, is imparted with the excellent ink repulsive property to the silicone rubber layer and is free from the scumming is thereby obtd.

Title: Image forming device
Inventor: KUNISHI TAKESHI
IPC: G03G15/08
Filed: 1988-02-29
Abstract: PURPOSE:To prevent the occurrence of an image flowing phenomenon by varying the control of a fan so that ozone concentration in a device becomes small enough according to grinding power of each toner to the surface of an image carrier. CONSTITUTION:An air current forming means for forming an air current in the device in order to reduce the ozone concentration in the device is provided in the title device. For example, in case of forming an image in a developing device A13 where non-magnetic toner which easily causes the image flowing is used, ventilation is performed so that the ozone concentration in a device becomes small enough by rotating a fan in device A30 and a fan in device B31 which are the air current forming means with a high voltage. In case of forming the image in a developing device B14 where the magnetic toner which hardly causes the image flowing is used, the ventilation is performed so that the ozone concentration in the device becomes to such an extent that the image flowing is not caused by the magnetic toner by rotating the fan in device A30 and the fan in device B31 with a low voltage. Thus, the image of high quality where the image flowing phenomenon does not occur can be always obtained regardless of the kind of toner.
