Patent JP-H02189775-A (JP)
Title: Head positioning control circuit
Inventor: ASADA HIDEO
IPC: G11B21/10
Filed: 1989-01-18
Abstract: PURPOSE:To shorten the seek time by switching the speed control mode into the position control mode so as to optimize the transient response to the seek operation by a optimum timer time for each number of moving cylinder. CONSTITUTION:An optimum timer time with respect to each seek operation is stored in an arithmetic circuit 2 for each number of a cylinder subject to seeking. The arithmetic circuit 2 calculates a moving cylinder number by the seek operation depending on the content of an object cylinder register 3 and of a present cylinder register 4 and the timer time of a timer circuit 1 is set by the moving cylinder number. The timer circuit 1 starts counting when the magnetic head is moved up to a cylinder just before the object cylinder and outputs a switching signal 6 when the count is finished to switch the control mode of the head positioning control from the speed control mode into the position control mode. Thus, the seek time is reduced.

Inventor: ARNOLD R DAVID
IPC: G09G5/28
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To perform anti-aliasing display without inviting the loss of a stem or the like even for a small character. SOLUTION: The density map of the resolution of an output device is generated 30 from a bit map rendered by the resolution higher than the resolution of the output device by simple addition or the like and the adjusted density map is formed 40 from it. In adjustment, a table is utilized for instance and plural different mapping functions are prepared and made selectable so as to maintain high contrast corresponding even to a part where the loss is predicted like the stem. At least one value is mapped to the maximum density value of scaling for any mapping functions. The stem is detected based on the information of the standard stem width of font metrics.

Title: Interface circuit
Inventor: AIDA SEIICHI
IPC: H04N5/782
Filed: 1979-02-05
Abstract: PURPOSE: To realize the two-way interface with a simple circuit by providing one unit of the transistor plus one piece of the circuit.  
     CONSTITUTION: The emitter of transistor Tr31 is connected to terminal 21; the base is connected to power terminal of 5V through resistor 32; and the collector is connected to the joint of switch 28 and resistor 27 respectively. The voltage of 5V supplied from terminal 13 is supplied to the emitter of Tr31 when switches 11 and 28 are turned off, and thus Tr31 is turned off and the voltage of 12V is extracted  from terminal 25 to output terminal 29. With switch 11 turned on, the emitter  potential of Tr31 lowers down, and Tr31 is turned on to give the O-potential to terminal 29. This condition does not change although switch 28 may be turned on. At  this moment, switch 28 is turned on to change the collector potential into O, and  thus Tr31 is turned into the reverse transistor to be turned on. In this connection,  the emitter potential of Tr31 is turned to O, and also the joint of command unit 10  and switch 11 is changed into the O potential through terminals 21 and 14. Thus  terminal 15 is led out of the joint in order to know the switching state of switch 28 at the side of unit 10.

Thus a radiation beam is composed in the form of the sum of vectors of radiation beams as a whole.

Abstract: PURPOSE: To provide a highly reliable terminal connection by constructing a drain made of a metal film and the end portion of gate wiring using transparent electrically conductive films. CONSTITUTION: A metal film is formed on a transparent insulated substrate and machined on drain wiring 2, a source electrode 3 and an added capacity electrode 4. Then, a semiconductor layer 6, a gate insulated layer 7 and a electrically conductive metal film are formed and gate wiring 8 is made. A protective insulated layer is formed and etched, exposing the end portions of the gate wiring and the drain wiring and a pixel electrode section. By forming a transparent electrically conductive film and eliminating the unnecessary portion of the transparent electrically conductive film by using a lift off method for erasing resist, a drain wiring end portion ITO 14 and a gate wiring end portion ITO 15 are formed.  Thus, since the same ITO is used for the drain wiring, the source electrode and the pixel electrode, the drain wiring, the source electrode and the pixel electrode are manufactured by performing film formation and a photolithographic process once.

Abstract: PURPOSE:To prevent erroneous detection of the fully charged state of a secondary battery having such characteristics as the temperature variation rate increases under fully charged state regardless of abrupt temperature variation due to external conditions, e.g. variation of ambient temperature. CONSTITUTION:A measuring means 2 measures the temperature Ta of a secondary battery 1 and calculates a temperature rise rate Ta'.
