Title: Input buffer dependent on power supply
Inventor: HAMETSUDO GAASEMI
IPC: H03K19/086
Filed: 1993-09-22
Abstract: PURPOSE: To provide a power source dependent input buffer to be used especially with a low power supply voltage. CONSTITUTION: This power source dependent input buffer 20 having a different amplifier 22, emitter follower transistors 29 and 32, level shift resistors 30 and 33 and power source dependent current sources 31 and 34 receives an ECL input signal related with a positive power supply voltage and supplies a buffer level shift signal related with the ground. The current sources 31 and 34 receive a power source dependent bias voltage to be changed while being related with the change of positive power supply voltage. On the other hand, a voltage drop between resistors 30 and 33 is changed concerning the positive power supply voltage so as to fix the buffer level shift signal in respect to the ground.  The power source dependent input buffer 20 is provided to be used with the low power supply voltage (such as 3.3 V), power consumption is reduced as a result and further, a much wider margin can be obtained on a following stage like a level converter.

IPC: G06K9/36
Filed: 1991-10-04
Abstract: PURPOSE:To correct the perspective distortions of images that are caused in the case where the images are obliquely photographed at the front of them. CONSTITUTION:An orthogonal grating is applied onto a plane where a photographing subject exists, and the three-dimensionalspace coordinates of each lattice point are obtained at a three-dimensional coordinate computing part 1 and then orthogonally converted into the image pickup system fixed coordinates at a three-dimensional coordinate converting part 2. Furthermore the fixed coordinates are projectively converted into a two-dimensional. plane at a two-dimensional discrete coordinate calculation part 3. Thus the coordinates of a picture element is turned into an integer. Then an offset calculation is applied to the coordinates of the picture element through an address calculation part 4 so that the coordinates correspond to the address of a storage 5 storing an original image. An access is applied to the original image data through an address shown by the result of the offset calculation. Then the original image data undergo the two-dimensional interpolation through a two-dimensional interpolation calculation part 6 based on the weight coefficient which is decided by the remainder obtained through the preceding conversion of the coordinetes into an integer. The address of a storage 8 where the interpolation value is stored is decided by applying the offset calculation to the orthogonal lattice coordinates through an address calculation part 7.

Filed: 1986-10-30
Abstract: PURPOSE:To make the space of a whole apparatus smaller and to reduce heat loss, by passing a circulation duct through a drying oven and connecting it between a radiant heat panel and a circulation fan. CONSTITUTION:A hot air introduced in a system is introduced in a radiant heat panel 3 from an air supplying hole 11 through an air supplying duct 8 by means of a circulation fan 4. A radiant heat is generated at the surface of the radiant heat panel 3 by using this hot air as a heat source and a resin- impregnated sheet 1 is thereby dried under heating. The hot air in the radiant heat panel 3 is moved to a panel part 12 of circulation duct 5 and is returned to a circulation fan 4 through a pipe part 14. And, so forth, the hot air is circulated between the radiant heat panel 3 and the circulation fan 4. As the circulation duct passes through a drying oven 2, it is possible to shorten the length of the pipe of the circulation duct 6 outside the drying oven and to prevent that the space of the whole apparatus becomes larger. Because the length of the circulation duct 5 exposed outside the drying oven becomes short, it is possible to reduce heat radiation and heat loss.

The capacity of the scanning lines is, therefore, increased. Sufficient writing is executed without flickering of the contrast within the image plane even if the size of the liquid crystal panel is increased and the density of the picture elements is increased.

CONSTITUTION:Air entering a surge tank 22 from a suction pipe 20 is divided into two parts at an intermediate partition wall 34 and dividedly flows into suction branch pipes 26A-F at banks 14A and 14B, respectively. At the opposite side to the suction port side 32 of the surge tank 22, there is provided with an extension part 44 in a spot deeper than the innermost branch pipe 26F. A butterfly valve 50 is installed as being situated in the extension part 44 of the partition wall 34. In time of engine high speed, this valve 50 is closed, while each bank uses the surge tank 22 as making it into halves (36 and 38) and in time of low speed, the valve 50 is opened, using the whole capacity. Since the butterfly valve is little in suction resistance and situated in an innermost end, suction circulation is also little, thus the valve comes to no resistance.
