Patent JP-S5998226-A (JP)
Title: Pulse driving device
Inventor: KATOU SHIYOUZOU
IPC: H02M1/08
Filed: 1982-11-27
Abstract: PURPOSE:To make the work load of a load for one pulse input approximately constant, by supplying power to the load from the power supply start until the sum of a voltage proportional to the load current and a voltage proportional to the integral value of the load current becomes a certain value. CONSTITUTION:When the pulse input is inputted from an input device 11 to the non-inverted input terminal of an operation amplifier OP1, a transistor TR18 is made conductive to start the power supply to a solenoid coil 19. When a current is flowed to the coil 19, a voltage proportional to the current is generated in a resistance 17. Since an operational amplifier OP2 takes this voltage as the input and constitutes an integrating circuit together with a capacitor 24 and a resistance 22, the voltage of its output terminal G is the sum of a voltage proportional to the current of the coil 19 and the integral value of the current of the coil 19. When this voltage of the sum exceeds a voltage at an intermediate connection point, the voltage of an output terminal A becomes 0, and therefore, the TR18 is cut off to break the power supply of the coil 19. Thus, the work load for one pulse input is made constant approximately while compensating the variations of a power source voltage, a winding temperature, or the like.

IPC: G03F9/00
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To stably obtain the best focus by exposing a reticle pattern to form its latent image on the surface of a photochromic material, applying an auto focus light on the latent image and measuring the size of this image from detected light reflected thereon. SOLUTION: When an exposure light 9 is focused, the latent image of a pattern 7 of reticles 8 is largely formed on a photochromic material 3. When the light 9 is not focused, the light intensity on the surface of the material 3 of a substrate 4 is reduced to result in a small-sized latent image of the pattern 7 of the reticles 8 formed on the material 3. In such way the change of the intensity of the light 9 is detected by an auto focus detector 12 and stage 1 is moved back and forth in a direction Z to control for the best focus.

Filed: 1989-08-11
Abstract: PURPOSE:To change the display with the sense or speed approximate to that of the switch manipulation of a user by comparing the received switch data with the display value, and switching the speed or step to change the display value in correspondence to the difference. CONSTITUTION:At a communication timing t1, for example, since the receiving data of a receiving circuit 21 is '10' and an output value of an up/down counter 25 is '2', a difference output of a subtractor circuit 22 is '8'. The counter 25 changes only Q3 output value in an upward direction. In other words, the display value of a display device 28 is changed every 4 steps. When the output value of the counter 25 agrees with the receiving data, a clock stopping signal CS is sent to an AND gate 29 from a comparison circuit 23, thereby stopping a clock signal CK and eventually stopping the up-counting operation. Similarly, at a communication timing t2, since the difference output is '4', the display value is changed every 2 steps. Moreover, at a communication timing t3, the difference output is '2', and accordingly, the display value is changed every one step.

Title: Advance acquisition processing system for page
Inventor: SHAMOTO NOBORU
IPC: G06F12/06
Filed: 1987-08-24
Abstract: PURPOSE:To enable a memory to acquire pages at a high speed without affecting greatly existing software by changing the memory offset of a user space by a requested extent with respect to an area that is acquired in advance by an advance acquisition macroinstruction. CONSTITUTION:An advance acquisition macroinstruction 11 is newly added so that the change is possible only at the side of a kernel space 16. A memory gives an advance acquisition request by the macroinstruction 11 and a user page advance acquisition processing part 14 performs advance allocation for the memory. Thus the offset is changed to a position (c), for example, at the kernel side. When a user application 12 delivers an area acquisition request by an area acquisition macroinstruction 13, a user page acquisition processing part 15 omits kernel processing to acquire pages and expands the area of a data part just with the change of the offset of the user side. In this case, the processing speed is increased since said kernel processing is omitted.
