Title: Production of resin composition for toner
Inventor: OKUTO MASAZUMI
IPC: G03G9/087
Filed: 1993-12-15
Abstract: PURPOSE:To provide the production with which a vinyl polymer and a resin can be uniformly dispersed in the resin composition and the resin composition having excellent blocking resistance, offset resistance and fixation properties can be produced by charging the resin having a specified melt viscosity into the molten vinyl polymer and adjusting the viscosity of the vinyl polymer at the time of charging the resin into it to a value higher than that of the resin. CONSTITUTION:In this production, the resin in a molten state is charged into the vinyl polymer in a solution state formed by dissolving it in a solvent or in a molten state formed by heating it to mix them with each other. The melt viscosity of the resin is within the range of 0. 5 to 100ps and when the melt viscosity value is either higher than the upper limit or lower than the lower limit of this range, the dispersion of the vinyl polymer and the resin in the resulting resin composition becomes inferior. Further the viscosity of the vinyl polymer at the time of charging the resin into it is required to be higher than that of the resin. When this viscosity of the vinyl polymer is lower than that of the resin, the dispersion of the both components of the resin composition becomes inferior and the resin composition hardly shows uniform characteristics. The mixing ratio of the resin to 100 pts.wt. of the vinyl polymer is preferably 0.1 to 30 pts.wt.

Title: Fuel injection pump for internal combustion engine
Inventor: ANDORE BURUNERU
IPC: F02M59/44
Filed: 1988-12-15
Abstract: PURPOSE: To reduce manufacturing cost by a structure where an element has an inner bore and is supported on a drive shaft thereby, and is axially and radially displaceable against housing parts, and a relief line is connected to the suction side of a feed pump. CONSTITUTION: A seal element 6 has an inner bore and is supported on a drive shaft 2 in the manner of a sliding bearing thereby. The element 6 is axially and radially displaceable against surrounding housing 1 parts. Thus, it is possible not to consider the guide function with respect to the processing quality of the sliding bearing and manufacture it with considerable tolerance. A relief line 12 is connected to the suction side of a feed pump 4. Therefore, passive exhaust of leakage oil is turned into active suction by negative pressure at the suction side of the feed pump 4. Thus, the compression of the shaft packing against the drive shaft 2 becomes less, and as the leakage oil flow is cut off, a roller bearing can be used as the drive bearing and cost can therefore be reduced.

Abstract: PURPOSE:To facilitate a speed control of a control object by making an array of a moving extent per unit time from a target moving extent and a target speed, adding an array of a moving extend '0' or a moving extent being equivalent thereto, and averaging the array in order. CONSTITUTION:Suppose that a moving command is inputted to a control part 10 to move a control object from the point A to B with the velocity of 50mm/sec. where the distance between the positions A and B, the projected distance of the line AB in the X axis direction, and the distance in the Y axis direction are 500mm, 400mm and 300mm, respectively. The control part 10 derives a moving extent >=X=50/500X400=40mm per unit time in the X axis direction (Y axis direction) from a given data and arrays it. Subsequently, a moving extent per unit time is obtained by adding an array of a moving extent '0' before and after the array, putting a code at every unit time, deriving an average value, while shifting the unit time one by one and executing the averaging. This moving extent becomes a speed command in the X axis (Y axis) direction. By adding successively these speed commands, a moving distance in the X axis (Y axis) direction from the position A is obtained. By comparing with the present position outputted from a position detector 9, a position command in the X axis (Y axis) direction is obtained and outputted to a subtracter 4.

Title: Synchronization timing control device for camera
Inventor: TOKUNAGA TATSUYUKI
IPC: G03B7/16
Filed: 1990-11-20
Abstract: PURPOSE:To set limit timing for panoramic photographing in a wide range by setting limit of shutter timing for flashing, at the time of panoramic photographing, on a shorter timing side from limit at the time of normal photographing. CONSTITUTION:The selection of a stroboscope mode causes a microcomputer 1 to send dimming information to a stroboscope emission control circuit 5, and to communicate with a lens control circuit 2 to control a diaphragm. Turning-on of a X contact commences flashing of a stroboscope and stops emission after suitable exposure in the circuit 5. Here in a panoramic mode, e.g. the lower half of a picture plane is covered with a shading member, consequently the X contact is turned on when a first blind reaches a position X 2-1, and in a normal mode, the X contact is turned on when the first blind reaches a position X 1-1. This emits the stroboscope at the time of shutter full admission in either cases.

Title: Semiconductor chip structure
Inventor: IIZUKA MICHIO
IPC: H01L23/29
Filed: 1987-12-16
Abstract: PURPOSE:To improve moisture-resistant properties by employing a structure wherein an insulating film is formed on the rear of a photosensor, i.e., on the opposite side to the photosensor or the photosensor is surrounded by the insulating film. CONSTITUTION:P-N-P-N devices are composed of an N-type semiconductor substrate 1, P-type regions 2 and N-type regions 3. Further, an insulating film 4 is provided under the N-type semiconductor substrate 1 by sputtering of SiO2. The P-N-P-N devices are separated by a canal 5. The chip is insulated from a lead frame 6 by resin 8 with which the insulating film 4 is bonded to a support plate 7 by thermocompression bonding and is fixed to the lead frame 6 with mounting adhesive 9. When a leakage current is measured between an anode 10 and a cathode 11, the current flows through a loop (a) composed of the P-type region 2, the N-type semiconductor substrate 1, the P-type region 2 and the N-type region 3. However, as the P-type region 2 on the side of the cathode 11 blocks the current, the leakage current is minimal. By employing a structure wherein the insulating film is provided beneath the P-N-P-N device or the insulating film is provided beneath the P-N-P-N devicevand further the support layer is provided beneath the insulating film, moisture penetration through the boundary between the resin part and the lead frame at the time of a moisture-resistant properties highly accelerated test gives little influence upon the characteristics and the leakage current is suppressed to be minimal and misoperation can be avoided.

Title: Picture identification system
Inventor: FUNADA MASAHIRO
IPC: H04N1/407
Filed: 1988-12-16
Abstract: PURPOSE:To surely discriminate a character line picture area from a halftone picture area by checking whether or not a sudden change of density is recognized in the range of the input picture element data and its peripheral picture element data groups and furthermore whether the sudden changes of density are continuous in the specified direction or not. CONSTITUTION:The digital picture signals are delayed by the line memories 102 and 103 at a density changing point detecting part 100. Then 3 lines are inputted to a detecting circuit 104 at one time. The circuit 104 fetches the density data for each (3 X 3)-picture element block in the data equivalent to 3 lines and outputs the density data as the density change information. Each density change information is fetched by a deciding part 101, and the deciding result showing whether a noted picture element is equal to an edge part or not is outputted. In other words, it is decided whether the periphery of the noted picture element is included in an edge part of a binary picture or not based on the continuity of the density change directions as well as the density change of the input picture element. As a result, a character line picture area is surely discriminated from a halftone picture area.
