Title: Input system for cursor position
Inventor: OKI FUMIO
IPC: G06F3/038
Filed: 1985-04-01
Abstract: PURPOSE:To shift quickly a cursor to the desired position by correcting the degree of displacement into the larger value when the degree of displacement is larger a certain level and changing the position of the cursor according to the corrected degree of displacement. CONSTITUTION:A revolution detecting part 1 detects the revolution of a mobile ball. A displacement degree counting part 2 counts the output of the part 1 to obtain the count value proportional to the degree of displacement of the mobile ball. A control part 4 starts a correction part 3 every fixed time. Then the part 3 reads the count value out of the part 2 to give correction to it so as to obtain larger value and delivers it to the part 4. Then the part 4 receives the corrected value from the part 3 and calculates the degree of shift from the present position of a cursor to shift the cursor on the screen of a display device 5. This action is repeated every fixed time and therefore the revolving speed of the mobile ball is proportional to the count value of the part 2. Thus the revolving speed of the ball is increased in case the count value is large after correction of the revolving speed. Then the cursor can be shifted quickly to a desired position.

Title: Forming method for thin film
Inventor: TAMURA YOSHITAKA
IPC: B41F3/34
Filed: 1979-06-06
Abstract: PURPOSE: To provide a thin ink film which is uniform and free of pinholes by rotating a roll coater and a form roller in the opposite directions, in a method of forming a thin ink film on an ink table in the offset lithography.  
     CONSTITUTION: A form roller 3 is rotated reversely relative to an ink stand 1 so as to feed an ink 7a onto an ink table 2. After the ink is fed, a roll coater 5 is raised as indicated by the locus 14 of the roll, so that a gap 15 is returned to the original. In this method the thickness of the film of ink 7a can be controlled by changing the pressure between the form roller 3 and an ink distributing roller 4, the revolution rate of the roller 3 or the traveling speed of the roller 3. Owing to the reverse rotation of the form roller 3, the precedingly applied ink 7a' is scraped (ink 7d) by the roller 3, so that the ink 7c on the roller 3 forms an ink film of uniform thickness on the ink table 2.

Title: Semiconductor device
Inventor: TAKAHASHI TAKESHI
IPC: H01L29/73
Filed: 1990-03-20
Abstract: PURPOSE:To enhance the stability of an element characteristic by a method wherein the bottom of a conduction band of a third semiconductor layer is made higher than the bottom of conduction bands of a first semiconductor layer and a second semiconductor layer and the top of a valence band of the third semiconductor layer is made lower than the top of valence bands of the first and second semiconductor layers. CONSTITUTION:The surface of a p-type semiconductor layer 1 and an n-type semiconductor layer 2, especially a p-n junction part exposed on the surface, is covered with an i-type semiconductor layer 3 as an insulating and protective layer. The bottom of a conduction band of the i-type semiconductor layer 3 is made higher than the bottom of conduction bands of the p-type semiconductor layer 1 and the n-type semiconductor layer 2; the top of its valence band is made lower than the top of valence bands of the p-type semiconductor layer 1 and the n-type semiconductor layer 2. As a result, conductive particles are confined. Consequently, the movement of the conductive particles on the surface of the p-type semiconductor layer 1 and the n-type semiconductor layer 2 and at the p-n junction part exposed on the surface is limited, and the non-light-emitting recombination at an interface is suppressed. Since the i-type semiconductor layer 3 is intrinsic, it functions as an electrical insulation layer with reference to electrodes 4.

Title: High-voltage ageing of cathode-ray tube
Inventor: INOUE KATSUYOSHI
IPC: H01J9/44
Filed: 1981-05-12
Abstract: PURPOSE:To enable a spot knocking method to be carried out without causing any electric discharge inside a cathode-ray tube during its operation by applying pulses with negatively high voltage to the socket side of the cathode-ray tube, and maiing either an anode terminal only or both the anode terminal and an external conductive film to have a grounding electric potential. CONSTITUTION:An anode terminal 49 and an external conductive film 492 have a grounding electric potential. As is seen from the direction of a rectifier 43, a negatively high pulse voltage is applied to a socket 50 so as to carry out high- voltage ageing by spot knocking. Since all of the external conductive film 492, an internal conductive film 491, an explosion-proof metallic tool 481, and the metal back layers of a shadow mask and a phosphor screen have a grounding electric potential, a floating capacity 52 of a tube 48, which corresponds to only the capacity between opposed electrodes connected to an anode and the socket 50, becomes extremely small. Consequently, high-voltage ageing can be carried out by strickingly effective spot knocking without destroying the wave form of the negatiely high pulse voltage.

Title: Developing method
Inventor: IMAI EIICHI
IPC: G03G13/08
Filed: 1983-04-21
Abstract: PURPOSE:To obtain a developing method having high faithfulness and stable picture quality by limiting the range of total quantity of toner charge in a unit area on toner carrier. CONSTITUTION:The preferable range of the absolute value of toner charge quantity in a unit area on the carrier is 3X10<-10>C/cm<2>-10<+7>C/cm<2>. When the range is exceeded, fogging of a non-picture part or unsufficient development due to the increment of reflection force with the carrier is generated, so that various defects such as reduction of toner density or generation of ghost may be generated. For the toner weight in a unit area on the toner carrier, 0.1-20mg/cm<2> is preferable and 0.3-10mg/cm<2> is more proper. If the toner weight per unit area is small, i.e. when a toner layer is extremely thin, it may be impossible to obtain a picture of fine quality even if the quantity of charge is proper. When the toner weight is extremely large, i.e. when the toner layer is extremely thick, similar inclination can be recognized.

IPC: H04N5/21
Filed: 1989-03-24
Abstract: PURPOSE:To make ghost detection stable by selecting either output signal of the output signals of 1st and 2nd ghost cancellation reference signal (GCR) signal extraction pulse generating circuits for ghost elimination so as to check whether or not a vertical synchronizing signal separator circuit of a television signal is correctly operated. CONSTITUTION:When a pulse to fetch a GCR signal is generated by using 4fsc, it cannot cope with the case with occurrence of a discontinuous vertical synchronizing signal caused at the changeover of a camera. Then a vertical synchronizing confirmation circuit 119 monitors the discontinuity of the vertical synchronizing signal and when discontinuity takes place, a 1st GCR signal extraction pulse generating circuit 116 is used to generate again a GCR signal extraction pulse at a normal position and then a 2nd GCR signal extraction pulse generating circuit 116 is used to generate the GCR signal extraction pulse. Thus, the system copes with even the discontinuity of the vertical synchronizing signal to detect ghost stably at all times.
