Title: Led printer
Inventor: MIYABE KOICHI
IPC: G03G21/14
Filed: 1988-05-25
Abstract: PURPOSE:To prevent a carrier from sticking to a surface of a photosensitive drum, by a method wherein just after generation of off of a power source during a printing cycle, a charging device, a driving motor, and further a developing bias are stopped by certain timing and further, a LED head is wholly lighted for a certain time. CONSTITUTION:Just after generation of off of an Ac power source on the way to a printing cycle, a motor ON signal driving a DC motor of a photosensitive drum 1 and a CH ON signal applying a charge voltage CH to a primary charg ing device 2 are immediately turned off. Further, a LED head 3 is wholly light ed. Furthermore, after a certain time has elapsed, a developing bias is decreased. A charged area is not formed thus on the photosensitive drum rotating by inertia after stop. Further, the charged area on the photosensitive drum 1 rotat ing by inertia is made almost zero V. Furthermore, the developing bias is kept alive until an area on the photosensitive drum 1 of a developing roller side from the LED head 3 has passed a front of the developing roller 5. Therefore, a carrier can be prevented from sticking to the front of the photosensitive drum 1.

Title: Recording and reproducing device
Inventor: TAKANASHI RYOYU
IPC: G11B9/08
Filed: 1989-05-22
Abstract: PURPOSE:To apply color processing such as color demultiplex and color separation simply by providing a frequency decomposing filter means to an electromagnetic radiant ray for recording and reproduction. CONSTITUTION:An optical image of an object 28 is made incident in a photoconductive layer 22 of a recording head 20 through a pickup lens 30 and a recording medium 10 respectively. In this case, the light is decomposed into the 3 primary colors by the filter mask action of a color separation filter layer 16 and made incident in the photoconductive layer 22 through a transparent electrode 14 and a charge storage layer 12. The incident light is absorbed in the photoconductive layer 22 to generate an electron-hole pair and a hole image or positive electric image corresponding to the optical image of the object 28 is formed on the surface of the photoconductor layer 22, Then discharge is caused between opposite faces between the charge holding layer 12 and the photoconductor layer 22 due to the application of a voltage of a power supply 32 and the charge image corresponding to the optical image of the object 28 is transferred onto the surface of the charge storage layer 12. Thus, color multiplex and color separation are easily implemented with simple constitution.

Title: Manufacture of semiconductor device using high resistance element
Inventor: WATANABE KUNIO
IPC: H01L27/04
Filed: 1991-04-30
Abstract: PURPOSE:To provide a method for manufacturing a semiconductor device having a high resistance element, which can sufficiently reduce a resistance value of a polycrystalline silicon film to become a wiring region and prevent a disconnection of a metal wiring. CONSTITUTION:A photoresist film 7 is pattern-formed at least on a region to form a high resistance element of a polycrystalline silicon film 6. With the film 7 as a mask an impurity is ion implanted in the entire surface. Thus, a resistance value of a wiring region of the film 6 is reduced. After the film 7 is removed, an oxide film is grown on the entire surface. Since the wiring region of the film 6 is not etched, its resistance value can be sufficiently reduced. Since the oxide film is provided after the film 7 is removed, the oxide film can be flattened, and a disconnection of a metal wiring can be prevented.

Title: Electric discharge machine
Inventor: ITO TETSURO
IPC: B23H7/02
Filed: 1986-06-03
Abstract: PURPOSE:To prevent accidents due to damage of an electrode, by detecting the degree of insulation of an insulative machining fluid existing in the interpole gap and by comparing thus detected value with a reference value to control whether pulse voltage applied across the interpole gap is held until it is discharged or the turn-on and -off are repeated. CONSTITUTION:A control instruction signal generating device 17 superposes high frequency alternate voltage from an electrical sources 18 during a deionizing period or the quiescent time of pulse voltage applied between a wire electrode 2 and a workpiece 1 from a machining power source 15, and a current detector 6 detects interpole leakage current running due to the lowering of insulation of the machining fluid 3 which is caused by machined chips. so that thus detected current is compared with a preset reference value to discriminate the interpole condition. with the result of the discrimination a control instruction signal is fed to a control device 14 and the machining power source 15, and therefore control is made such that pulse voltage applied across the interpole gap is held until it is discharged when the interpole condition is satisfactory, but the turn-on and -off are repeated when the interpole condition is not good. Thus, it is possible to prevent breakage of the wire electrode without the machining rate being lowered, and to aim at enhancing the machining efficiency.

Abstract: PURPOSE:To make the protection of load and the effective acquisition of energy compatible by charging a battery at voltage within the tolerance of load during load operation and charging the battery at voltage higher than said voltage within the tolerance of load during the close of load. CONSTITUTION:When the number of revolution of a wind mill 1 reaches the set number of revolution or more determined by a revolution setting means 8, a switching element 13 is driven by an output control circuit 18, and field currents flow through a field coil 12, thus starting power generation. A current command value corresponding to the difference of the number of revolution of the wind mill and the set number of revolution is outputted by an amplifier 10 at that time, and an amplifier 16 controls field currents in response to the difference of the current command value and a current detecting value. When voltage detected by a voltage dividing circuit 20 reaches the voltage set by a voltage setting means 21 or higher, on the other hand, an overvoltage correction command is outputted. When a load-break switch 5 is opened, the voltage division ratio of the voltage dividing circuit 20 is increased, thus correcting overvoltage at a high voltage level.

Title: Layout verifying device
Inventor: TSUZUKI KATSUO
IPC: G06F17/50
Filed: 1994-06-10
Abstract: PURPOSE:To output a precise error position and to shorten the time required for layout verification by selecting a case where an error occurs in the block of a hierarchy or in a hierarchy to which the block is connected more preferentially than a case where the number of the errors becomes a minimum. CONSTITUTION:A corresponding means 17a decides an initial corresponding point and makes net list circuit information 13 correspond to layout circuit information 16. A hierarchy priority correspondence judgement means 17b recognizes the presence or absence of the error being a corresponding result. When the errors occur by straddling over the plural block or the plural hierarchies, re-correspondence is judged to be required even if the number of the errors is small, a part where correspondence can be executed by the other combination is abolished and a processing is returned to a former one. When re-correspondence is unnecessary, a hierarchy priority correspondence selection means 17c selects correspondence evaluating plural obtained correspondences by using an evaluation value which take precedence over correspondence where the error occurring in the block of the hierarchy or the hierarchy to which the block is connected are less and where the blocks with errors are less compared to correspondence whose number of the errors becomes a minimum, and setting the correspondence to be a collated result.
