Title: Image forming device
Inventor: MIURA YASUSHI
IPC: G03G15/05
Filed: 1987-02-25
Abstract: PURPOSE:To obtain a sharp image having high contrast and less scumming by exposing the image to a toner layer coated on a base body and providing a 2nd electrostatic charging means which charges the exposed toner to a prescribed potential. CONSTITUTION:The photoconductive toner 3 is uniformly coated by a coating means 2 on the conductive base body 1 to form the toner layer and the toner layer is uniformly electrostatically charged by the 1st charging means 4. The image is then exposed to the toner layer by an exposing means and the exposed toner 3 is charged to the prescribed potential by the 2nd charging means. Strong electrostatic force is acted from a transfer means 8 to the toner 3 charged by the 2nd charging means 6 by which the toner is transferred onto a transfer material 7. The force that a transfer electrode 8 attracts the positive-charged toner is, therefore, extremely strong; in addition, the need for setting the potential of the transfer electrode at a slightly higher level in order to increase the contrast is eliminated. The image having the high contrast and no scumming is thereby formed.

Title: Navigation device
Inventor: TATEISHI NAOFUMI
IPC: G06T11/60
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To prevent a wasteful consumption of memory when in use without causing the deterioration in the operational performance for a user in a navigation device in which location data showing driver's own location are stored one after another while travelling. SOLUTION: When the data on latitude and longitude are obtained while travelling, whether the data of a location whose distance to the present location indicated by the newly obtained data on latitude and longitude is under a certain level already resides in a storage device is judged (SD9). When it does not reside ('NO' SD9), the value of a memory flag MFLG is altered to the value '1' which permits the obtained data on latitude and longitude to be stored in the storage device. Contrarily when it resides ('YES' SD9), the value of the memory flag MFLG is processed to maintain to be the value '0' which inhibits the obtained data on latitude and longitude to be stored in the storage device.

Abstract: PURPOSE:To improve the working speed of a signal output circuit consisting of a differential amplifier and a buffer. CONSTITUTION:In the case that input voltage VIN is higher than the input voltage of the last time, that is, in the case that the gate voltage of a transistor N1 is higher than the threshold voltage of the transistor N1, the transistor N1 is turned into an ON-state, and capacitive load 2 is charged, and the voltage of an output terminal 3 is raised to the voltage corresponding to the input voltage VIN. On the other hand, in the case that the input voltage VIN is lower than the input voltage of the last time, that is, in the case that the gate voltage of the transistor P1 is lower than the threshold voltage of the transistor P1, the transistor P1 is turned into the ON-state, and the capacitive load 2 is discharged, and the voltage of the output terminal 3 is lowered to the voltage corresponding to the input voltage VIN. In this signal output circuit, the buffer executes push-pull operation, and since it functions as the buffer of tow impedance not only in the case that a current is outputted but also in the case that the current flows in, a discharge transistor need not be provided so as to discharger the capacitive load like in the past.
