Title: Image forming device
Inventor: WATANABE TAKESHI
IPC: G03G15/20
Filed: 1990-07-05
Abstract: PURPOSE:To obtain a high-quality permanent image with comparatively simple constitution by detecting the image ratio of an original, giving electric charge to a roller means and controlling the quantity of the electric charge which is given according to the detected image ratio. CONSTITUTION:A high voltage is given to the corona wire 12 of a corona generation device 6 from a high voltage power source 7. The actuation and the strength of the power source 7 is controlled by the DC controller 8. Besides, the controller 8 is actuated by a signal from an AE sensor 9 which reads the image of the original. The quantity of the electric charge given to a fixing roller 1 depends on a high voltage value impressed on the wire 12 of the device 6. However, the high voltage value is changed according to the image ratio of the original in such a case. Thus, excellent fixing without offset is executed with the comparatively simple constitution and the high-quality permanent image is obtained.

Title: Programmable logic array allowing reprogramming
Inventor: CHIYOU KENSHIYOKU
IPC: H03K19/177
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To obtain a programmable logic array with which related software is easily developed by general CMOS technologies by eliminating the need for a process for a special program device. SOLUTION: Data recorded in an AND-CAM cell array block 22 and data which are compared by the block 22 are inputted to a 1st recording module 20. The data from the module 20 are recorded in order for a recording mode of the block 22 and in match mode, a match signal is generated by comparing comparison data from the module 20 with data which are already stored. Further, a 1st address module 24 generates addresses sequentially in recording mode and supplies them to the AND-CAM cell array block 22, so that the data are stored in order in a storage area of the block 22. To the logic array PLA which is thus constituted, a 2nd recording module 28, an OR-CAM cell array block 30, a 2nd address module 32, and an output module 34 are added to make it possible to output data.

Title: Multipoint contact ball bearing
Inventor: OKUDA KOICHI
IPC: F16C19/16
Filed: 1993-07-20
Abstract: PURPOSE:To prevent any rotational failure from occurring by making a. contact angle at the time of having received radial load, larger than that at the time of having received axial load at a room temperature. CONSTITUTION:When a temperature rises and thermal expansion occurs in a housing H, such axial force as separating two constituent members 3a and 3b acts on a two-piece outer ring 3. In this case, an axial contact angle betaremains unchanged and it is about 28 degrees, but a radial contact angle alphabecomes smaller by degrees. In the case where the temperature has come to about 83 deg.C by way of example, this radial contact angle alpha comes to about 28 deg., namely, equal to the axial contact angle beta. In addition, when it has come to about 4.7 deg.C, a clearance is produced between both these constituent members 3a and 3b owing to the thermal expansion of the housing H, and a ball 4 comes into contact with these members 3a and 3b at a point different in time of room temperature. In this connection, the radial contact angle alpha comes to about 20 degrees, and it becomes smaller than the axial contact angle beta, but it comes to a proper value similar to the radial contact angle alpha in time of the room temperature. With the abovementioned, any possible rotational failure is thus preventable.
