Title: Magnetic toner for one component development
Inventor: YAMADA HATSUMI
IPC: G03G9/08
Filed: 1993-12-16
Abstract: PURPOSE:To uniformize the sticking of the inorganic fine particles to the colorant particles in the toner, to prevent the weakly charged or reversed-polarly charged toner particles from being generated and to reduce the generation of fogging in the image and scattering of the toner by specifying the amount of the releasing agent present on the surface of the colorant particles and the domain diameter of the releasing agent within the colorant particles respectively. CONSTITUTION:In this toner which consists of inorganic fine particles and colorant particles comprising a resin, a magnetic substance and a releasing agent, the amount of the releasing agent present on the surface of the colorant particles and the domain diameter of the releasing agent within the colorant particles are adjusted to 0.1 to 0.3 and 0.1 to 1.0mum respectively. At this time, the amount of the releasing agent present on the surface of the colorant particles can be adjusted by controlling the amount returned to the pulverizing process. The domain diameter of the releasing agent within the colorant particles can be controlled by adjusting the average degree of filling with the kneaded material of the kneader in the kneading process to a value within a prescribed range and controlling its width of variation to uniformize the dispersion of the releasing agent Thus, the uniform chargeability of the surface of the colorant particles can be attained to uniformize its chargeability at the time of adding the inorganic fine particles to it from outside and mixing them with each other.

Title: Speed change control device for automatic transmission
Inventor: ASAHARA NORIKI
IPC: F16H59/24
Filed: 1989-12-06
Abstract: PURPOSE:To reduce shock generated at the time of speed change by starting speed change with a transmission part with larger gear ratio difference before and after speed change at the time of performing the speed change of a first and a second transmission parts simultaneously and in reverse directions. CONSTITUTION:When a first transmission part 60 is high-gear shifted as well as a second transmission part 40 is low-gear shifted and the whole automatic transmission is up-shifted as in speed change from the second gear speed stage to the third gear speed stage, speed change is started first with the first transmission part 60 with the larger gear ratio. In this procedure of speed change, when the input shaft rotating speed of the automatic transmission becomes the final synchronous rotating speed, the speed change of the second transmission part 40 with the smaller gear ratio is started, as well as both transmission parts 60, 40 are feedback-controlled in the state of the input shaft rotating speed of the sutomatic transmission being maintained to the final synchronous rotating speed. Speed change shock can be thus minimized.

Title: Video camera, device suitable for use of the same and method for generating image display signal
Inventor: ANSONII EI ZOOTEIA
IPC: H04N5/361
Filed: 1994-12-20
Abstract: PURPOSE:To provide a dark signal correction device and a correction method corresponding to a secular change in an image pickup element without a memory of a large capacity. CONSTITUTION:The video camera is provided with a shading correction signal generator 30 generating an approximated signal to a distortion signal of a dark current, that is, black shading generated based on a scanning position of an image and subtracting the approximated signal from a picture signal generated by a camera for the usual image pickup operation to decrease black shading distortion. A scanning counter generates a position signal to represent a position of an image signal read at present. In order to generate a component approximated to a dark signal, the position signal is processed by the shading correction signal generator 30 by the function such as square and power of a constant number and weighting. An adder subtracts the approximated value of the obtained distortion signal from the image pickup device signal to reduce the black shading. The shading correction signal generator 30 selects a function from plural functions automatically or expresses a function by a lookup table.

Abstract: The support has at least two laterally arranged support units (9), which each contain a spring element (5), at least one spring plate (8) and at least one rail-type bearing piece (10) which is essentially rectangular in plan view, consists of a rubber-elastic material, and via which the spring plate 8 is supported against the adjacent vehicle part - body (1) or bogie (2). The bearing pieces (10) are each arranged with their long sides oriented transversely to the longitudinal direction (x) of the vehicle. Correspondingly, the spring plates (8) can be inclined in relation to the adjacent body (1) or bogie (2) in each case by a relatively large angle of inclination in the longitudinal direction (x) of the vehicle and by a considerably smaller angle of inclination transversely to the longitudinal direction (x) of the vehicle. When the bogie (2) is rotated relative to the body (1), the spring elements (5) are each deflected to a different extent in the longitudinal direction (x) and the transverse direction (y) of the vehicle. By suitable selection of the ratio of the width (B) to the length (L) of the bearing piece (10), a predetermined ratio of the horizontal spring constants of the relevant support unit (9) acting in the longitudinal direction (x) and the transverse direction (y) of the vehicle can be achieved. By this means, the resistance to turn-out of the support can be influenced within a broad range. <IMAGE>

Abstract: PURPOSE:To adjust a desired print density in a short time and easily by changing light intensity over time during a single printing action, exposing to light a print pattern for adjustment and print it for each change, then determining a print density in accordance with print results. CONSTITUTION:A control device 3 changes a light intensity over time from a light image exposure device 2 during a single printing action, then exposes to light print patterns for adjustment 5a to 5d for each change in response to instructions in the density measurement mode. The control device sets a print density which should be set using an operating device 4 based on print results. That is, a light intensity over time is changed during a single printing action and print patterns for density adjustment 5 to 5d are printed through light exposure for each change. Consequently, print patterns 5a to 5 of respective light intensity over time are obtained in a single printing action. A pattern of specified density is selected from among printed patterns obtained as a result of printing. Thus the density can be adjusted in a short time and easily with accuracy.

Title: Production of semiconductor device
Inventor: IMAI SHINICHI
IPC: H01L21/302
Filed: 1995-12-07
Abstract: PROBLEM TO BE SOLVED: To lower the contact resistance by introducing oxygen gas to a silicon substrate where an oxide is subjected to contact hole etching, controlling the gas pressure to a specified level, and then applying a high frequency power thereby suppressing formation of high resistance layer on the surface of substrate. SOLUTION: While controlling the pressure in a reaction chamber to 10mTorr or above in order to remove a polymer deposited on the bottom of contact, oxygen gas is introduced and a high frequency power is applied to a coil thus generating an oxygen plasma. A bias voltage is then applied to a silicon substrate in order to attract oxygen ions thus removing the polymer in contact hole. When the gas pressure is low, plasma density is increased and the quantity of oxygen ions 21 being implanted into the silicon substrate is increased and thereby a high resistance thick oxide layer 22b is formed in the substrate. When the gas pressure is increased, plasma density is decreased and a thin oxide layer 22b is formed in the substrate thus decreasing the contact resistance. 22a represents a high resistance silicon oxide layer.
