Title: Preparation of insulator coated semiconductor fine particle
Inventor: SAITO YASUHIRO
IPC: B01J19/00
Filed: 1990-02-01
Abstract: PURPOSE:To enhance dispersibility without exerting adverse effect on the quality of a silica film by adding a water-soluble polymer to a treating solution composed of an aqueous hydrogen silicofluoric acid solution saturated with silica when a silica film is precipitated and formed on semiconductor fine particles using said treating solution. CONSTITUTION:In a method preparing insulator coated semiconductor fine particles wherein an insulator film is formed on the surfaces of semiconductor fine particles, a silica film is precipitated and formed on the semiconductor fine particles using a treating solution composed of an aqueous hydrogen silicofluoric acid solution saturated with silica and, at this time, a water-soluble polymer (e.g. 1-vinyl-2-pyrrolidone polymer) is added to the treating solution. As a result, dispersibility can be enhanced without exerting adverse effect on the quality of the silica film. For example, when the fine particles treated by this method are used in paint, good effect is imparted to both of the suppression of photocatalytic activity and physical properties such as gloss. Further, the capacity of light control glass can be enhanced and the weatherability life thereof can be markedly extended.

Abstract: PURPOSE:To execute the visual inspection of an article with a complicated shape on an on-line basis without using any large-sized computer by opening and closing analog switches of the 1st and the 2nd circuits alternately and outputting video signals of two scans at the same time. CONSTITUTION:A video signal outputted from the linear image sensor 3 of a camera 1 is inputted to a parallel circuit of the 1st circuit 6 constituted by connecting an analog switch 4 and shift registers 5 which have bits as many as bits of a linear image sensor 3 in series and the 2nd circuit 8 consisting of only an analog switch 7. Then, the analog switches 4 and 7 are connected to the Q terminal 11 and Q terminal 12 of a J-KFF 10 connected to the start pulse generator 9 of the linear image sensor 3, and switched alternately in synchronism with the start pulse of the linear image sensor 3. Consequently, video signals of two scans are outputted at the same time, amplified 14 differentially, and converted by a microcomputer 15 into binary signals, which are inputted to a RAM and then processed.

Title: Feed controller
Inventor: KOMI HISAAKI
IPC: G05D3/12
Filed: 1987-02-02
Abstract: PURPOSE:To attain control based on the specification of a feeding length without lossing generality by setting up the number of pulses corresponding to one revolution of a connected motor and a feeding length based upon a feeding mechanism coupled with the motor. CONSTITUTION:A feed control device sets up conversion value between the number of pulses and the feeding length by using a conversion value setting means M5 on the basis of two information relating to the feeding mechanism M1 and the motor M2, i.e. the number of pulses corresponding to the one revolu tion of the motor set up in a pulse number setting means M3 and the feeding length corresponding to one revolution of the motor 1 set up in feeding length setting means M4. A motor driving means M6 converts the specified feeding length into the number of pulses by using the conversion value and drives the motor M2 on the basis of the number of pulses. Consequently, feeding control can be specified by a value corresponding to a read feeding length of millimeter unit.

Title: Field effect transistor amplifier
Inventor: IMAI SUKENORI
IPC: H03F3/34
Filed: 1988-02-03
Abstract: PURPOSE:To decrease the change in an output DC potential with respect to a change in an input DC bias and to facilitate multi-stage connection by changing the drain current of a field effect transistor(FET) being a load in response to the input DC bias. CONSTITUTION:A gate 26 and a case 28 of a load FET 15 are connected by a capacitive element 25 and a drain current IL flowing to the load FET 15 is changed by a DC potential of the source 28 because there is no DC coupling between the gate 26 and the source 28. Thus, even when an input DC bias VI is changed by a drain current IDS of a common source FET 11, the DC potential 28 of the load FET 15 is changed to change the drain current IL flowing to the load FET 15 corresponding to the change in the drain current IDS. Thus, the change in the output DC potential VO with respect to the change in the input DC bias VI is decreased and multi-stage by DC coupling is attained easily by using the level shift stage.

Filed: 1993-02-12
Abstract: PURPOSE:To improve mass productivity by shortening the outside shape working time of a substrate using a laser beam machine and to hardly generate voids in a resin when the resin is made into an electronic parts mounting device by resin molding. CONSTITUTION:The outside shape lines 5a of the substrate 5 for mounting the electronic parts of a sandwich structure formed with leads 1 held by an insulating substrate 3 are formed to an approximately an arced square shape in corner parts 6a thereof and the substrate is subjected to outside shape working by irradiating the substrate with a laser beam along outside shape working lines 6 of the same shape as the outside shape lines at the time of the outside shape working of the substrate 1. The directional change of the laser irradiated parts can be executed in the corner parts 6a without changing the speed at the time of of the directional change of the laser irradiated parts and, therefore, the irradiated parts are scanned at the specified speed and the simultaneous execution of the outside shape working and beveling is possible. Then, the beveling is executed and, therefore, the generation of the voids in the resin at the time of resin molding is substantially prevented.

Title: Automatic paper feeder
Inventor: TAKAHASHI SHIYUUICHI
IPC: G03G15/00
Filed: 1979-03-05
Abstract: PURPOSE: To feed paper securely by a method wherein the first and the second rollers are rotated in paper feed sense when a paper detector does not detect the presence of paper near the paper delivery side of the rollers, and the second roller is  rotated in the opposite sense when the presence of paper is detected.  
     CONSTITUTION: A predetermined number of sheets of paper out of paper sheet stack 4 are guided by a guide member 15 and inserted between a main roller 7 and an auxiliary roller 11. When paper detection result is negative, the roller 11 is rotated in sense b, so that the paper sheets are inserted smoothly between the rollers 7 and 11. When the tip end of the paper sheets reaches a detection position Q, the paper detection result turns positive, and the roller 11 is rotated reversely. As a result, the uppermost sheet in contact with the roller 11 is urged backward, while the lowermost sheet in contact with the roller 7 is fed forward. The sheets in the middle layer are fed backward sequentially, those nearer to the roller 11 being fed earlier. Thus, the paper sheets are delivered one by one, starting from the lowermost one in contact with the roller 7.

Title: Display
Inventor: ICHIMURA YASUHIKO
IPC: G01C15/00
Filed: 1987-02-06
Abstract: PURPOSE:To display the amount of completed operation for an operator conducting ground preparing operation or ground leveling operation so as to assist him to judge the operation, by changing over the display of the undulations of the whole of an operation area or an area around a vehicle. CONSTITUTION:CPU 5 computes topographical data from the position data of a moving body obtained from a three-dimensional position measuring device 1, and writes the topographical data in a storage device 6. Moreover, CPU 5 switches over line selectors 7 and 10, so as to change over a whole area display and a display of a part around the moving body. A display unit driving circuit 8 accesses all memory regions of a topographical data storage device 6 and sends the topographical data to a display unit controller 2. Meanwhile, a display unit driving circuit 9 accesses the present position of the moving body in the topographical data storage device 6 and the memory regions of the part around the body in the device 6 and delivers the data on the configuration of the ground to the display unit controller 2. Since two kinds of image planes can be changed over appropriately for display by switching over the driving devices 8 and 9 as occasion calls, a correct countermeasure can be taken even when the topography varies momentarily.
