Filed: 1990-10-31
Abstract: PURPOSE:To eliminate the need for a special electrode plate and improve the thin layer forming ability of toner by applying an electric field between a developer stirring and drawing member and a toner holder to electrostatically attract the toner in two-component system developer passing through a gap to the toner holder. CONSTITUTION:Toner in two-component system developer passing through between a toner holding roller 8 and a developer stirring and drawing member 4 is electrostatically moved to the toner holding roller 8 by an electric field which is applied between both of them, and provided for visualizing a latent image. In this case, carriers are not moved to the toner holding roller 8 and left in developer. It is thus possible to simplify a structure because no independent electrode plate is required and reduce cost further more.
Patent JP-H01135146-A (JP)
Title: Data sampling system
Inventor: SHIBATA YASUSHI
IPC: H04L7/027
Filed: 1987-11-20
Abstract: PURPOSE:To attain data sampling not affected by the communication speed and the phase difference between a reception data and an element timing due to the length of a cable by sampling a midpoint of the received data surely depending on the sampling timing generated based on a change point of the received data. CONSTITUTION:When there is any change point in the received data, a signal of an exclusive OR gate 10 is a signal A. A counter 12 counts by using a clock on a signal line 4 and is cleared when the signal A is logical 1 or the count reaches 31. The counter is operated in this way and the sampling timing of the received data is taken when the count of the counter reaches 15, the received data is always sampled at the midpoint. Even if the data of the same polarity is consecutive, since the received data T is synchronized with the element timing S formed based on the clock, the midpoint of the received data is not deviated. Thus, the sampling at the midpoint of the received data is attained without affected by the communication speed or the delay in the received data due to the length of cable.

Title: Magnetic recording and reproducing device
Inventor: ARAHORI MASANORI
IPC: G11B15/22
Filed: 1989-11-13
Abstract: PURPOSE:To stably stop a tape by controlling brake torque in varying a duty ratio of a control bus to a transistor for switching for absorbing counter electromotive force in accordance with moment of inertia of each reel. CONSTITUTION:The moment of inertia is detected from a tension change attending upon a variation in a prescribed tape speed. Then, a tape wound radius is calculated with a capstan FG pulse signal 7a or a timer roller pulse signal 8a and a ratio of reel FG pulse signals 5 and 6 to each other by a control circuit 11, and when this is subtracted from the previous moment of inertia, the moment of inertia of the reel itself is known. Moreover, in the circuit 11, the optimum brake torque is decided with the calculated moment of inertia, so that a duty ratio of the corresponding brake control pulses 14 and 15 to each other is calculated. When a power source is cut off, the pulses 14 and 15 are sent from a backup power source to a motor drive amplifier 10 to drive the transistors 12 and 13. By this method, the brake torque for reel motors 3 and 4 becomes optimum value corresponding to the moment of inertia, thus stopping stably the tape under traveling.

IPC: H04M3/36
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To prevent the whole electronic exchange from being congested brought by partial subscribers' terminals frequently repeating calling and dialing by performing calling regulation based on a dynamic regulation value. SOLUTION: A regulation value setting part 11 obtains the regulation value of each time zone from an each-time regulation value holding part 18 every hour to set a regulation value (n times/hour>T) of each subscriber's line to it, stores it in a regulation value storing part 12 and sets a regulation value corresponding to a traffic obtained from a traffic information obtaining part 19 every five minutes to store in the regulation value storing part 12. A comparing part 13 receiving a call refers to the regulation value storing part 12 and a timer part 14 and obtains a past calling time from a calling time storing part 15. Then at the time of 'present time- calling time T', the part 13 erases the calling time and when the number of the calling times except an erasing object is smaller than (n), the part 13 adds the present time to the calling time storing part 15.  A connection requiring part 16 requires connection to a connection control part 17 by information from the part 3. The connection control part 17 normally connects a call to a calling register 24 and at the time of regulation request, connects it to a talkie device 25 so that a talkie from the talkie device 25 is propagated to a terminal.

Title: Target detection device
Inventor: HAYASHI TAKAAKI
IPC: G01S7/32
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To allow even the accurate measurement of target length by preventing a single target from being erroneously detected as a plurality of targets. SOLUTION: A reflected signal from a target is received with a transmitter 1, a circulator 2, an aerial line 3 and a receiver 4 respectively forming a high distance resolution radar and, then, processed with a target detector 5. The received signal after A/D conversion is made into a binary signal with a threshold detector 5-2. The binary signal sometimes represents a plurality of line segments, depending on the shape or the like of a target and, therefore, is processed with a line segment extractor 5-3, for example, for half conversion or the like, so as to make detection signals on a linear line continuous to each other, thereby forming a continuous signal. Then, the distance and length of the target are identified and displayed with the continuous signal.
