Title: Seal impression reader
Inventor: YAMAZAKI NOBUHISA
IPC: G06T7/00
Filed: 1985-09-30
Abstract: PURPOSE:To remove a sealing field frame securely by checking the statistic distribution of levels of respective picture elements of the red of a seal impression and the black of the sealing field frame and finding a boundary level, and sectioning red and black. CONSTITUTION:The seal impression and sealing field frame on a seal registration form are scanned on a CCD 31 and respective picture elements are stored in an image buffer as multilevel data on 16 gradations. A histogram generation part 341 counts respective picture elements by level values 0-F to generate a histogram. A red-black slice level detection part 343 detects a slice level corresponding to extreme value points of bottoms between red and black from the generated histogram. A black area determination part 351 detect values larger than the slice level to determine a black level area. A black-and-white substitution part 352 substitutes all picture elements in the black level area with a level 0 to remove the sealing field frame. Similarly, data only the seal impression are extracted with a white-and-read slice level and outputted.

Abstract: PURPOSE:To manufacture a bipolar transistor which restrains a base current from being increased due to a crystal defect and whose linearlity is improved by a method wherein ions are implanted into a base region, the region is made amorphous, a heat treatment is then executed at a low temperature and a crystal is restored. CONSTITUTION:At a bipolar transistor, an N<-> type epitaxial layer 103 used to form base regions is made amorphous before ions of a base impurity are implanted, and the base regions 108, 108' which are formed are made amorphous. As a result, it is possible to increase the restoration rate of crystallinity in the base regions even by a heat treatment at a comparatively low temperature, it is possible to restrain a base current from being increased due to a crystal defect, it is possible to prevent a current-amplification factor from being lowered in the low current region of a collector current and it is possoble to improve its linearity. Since the heat treatment may be executed at the low temperature, the junction of impurity diffusion layers such as the base regions 108, 108' into which the impurity ions are implanted, an emitter region 110 and the like can be made shallow. This is favorable for its miniaturization.

Filed: 1992-08-17
Abstract: PURPOSE: To avoid echo compensation and a network structure which requires cost by applying packet processing to communciation information of line exchange into a communication cell with a comparatively fixed length for through-connection via an ATM exchange function section. CONSTITUTION: Two STM exchange functions are through-connected via, e.g. an ATM exchange function section ATM 1. In the case of connection between the connection sections STM1, STM2, a short-cell of a prescribed form is generated in a interface AUN 1. Thus, the connection sections are concerted via a switch frame SNB, and the cell is disassembled into a packet again in an interface AUN 2. In this case, a content is set to the short cell in a time slot of a time channel indicated by a valid part of the cell. Thus, the short cell is used only in the ATM exchange function section ATM 1. Thus, there is no generation of a fault of a prescribed protocol.

Filed: 1990-08-20
Abstract: PURPOSE:To enhance turning responsiveness, when the roll control of a vehicle body is carried out, by increasing the distribution rate of control pressure by means of a hydraulic-pressure sustaining means on the front wheel side when the steering angular velocity of the steering wheel is large, so that the turning characteristic of the vehicle can be brought into an under-steer tendency. CONSTITUTION:The transverse acceleration acting on a vehicle body 7 is detected by a transverse G sensor 31, and this is supplied to a controller 30 for calculating the control pressure of respective hydraulic actuators 14. The steering angle obtained by a steering angle sensor 33 is supplied to the controller 30 for being subjected to differential processing, and a steering angular velocity is obtained. When the vehicle is turned, if the steering angular velocity of the steering wheel increases beyond the dead zone, the front-wheel distribution rate alpha is increased to bring the turning characteristic of the vehicle into under- steer. Thus, the responsive frequency in the yaw direction to steering is increased, and with regard to the turning of the vehicle, the direction of the vehicle is quickly changed in the turning direction, so that the steering responsiveness of the vehicle can be enhanced.

Abstract: PURPOSE:To use a write pointer representing a write address properly at a time when an error occurs, and at a normal time, by providing a save register which stores the final address of a data group at a previous operation in a data buffer in which the data is stored. CONSTITUTION:The final address written by the data group is stored in the save register 3 at the normal time, and the storing of the address to the register 3 is prohibited at the time when the error occurs. Therefore, as the content of the save register 3, the final address of the data group at the previous operation at the normal time is stored in the register, and the input of the write pointer 2 selects the write pointer 2 at a current time at the normal time, and the final address at the previous operation at the time when the error occurs. By selecting the write pointer 2 by the output of error check, the data group at the normal time can be written again in an area where the data group is written at the time when the error occurs, and write control to always write only the data group at the normal time in the area of the buffer 1 is performed. In such a way, it is possible to read out only the data group at the normal time at the time of reading out a RAM, thereby, a whole throughput can be improved.

Abstract: PROBLEM TO BE SOLVED: To accurately compensate the influence of the fluctuation of the ambient temperature with a simple constitution by supplying a compensating current which is preset correspondingly to the ambient temperature to an electromagnetic coil. SOLUTION: A permanent magnet 1 is made of an appropriate material and a cylindrical pole piece 3 is attached to the lower surface of the magnet so that the piece 3 can be directed toward a Hall element 2. An electromagnetic coil 4 is arranged around the piece 3 with a bobbin made of a heat-resistant resin material in between and an ambient temperature detecting circuit is connected to the coil 4. The ambient temperature is found by measuring the resistance value of the coil 4 and a compensating current is supplied to the coil 4 correspondingly to the measured ambient temperature so that a compensating magnetic flux can be added. Therefore, the temperature of a non-contacting sensor can be compensated accurately even when the sensor is used at such a place that the ambient temperature fluctuates and the relative displacement of the magnet 1 to the element 2 can be detected accurately.
