Filed: 1987-03-30
Abstract: PURPOSE:To simply and easily execute processing similar to deformation unsharp masking without using special hardware by adding the difference between an image obtained by luminance conversion and a fading mask image to an original image. CONSTITUTION:The original image stored into a memory 1 is sent through an image bus 7 to a luminance converting device 2, luminance-converted and written into a memory 3. An image obtained newly onto the memory 3 is sent through the image bus 7 to a memory 4. Next, an image arithmetic unit 5 calculates the fading mask image of an image on the memory 4 and writes the prepared fading mask image into a memory 6. Thereafter, an image arithmetic device 5 obtains the difference between the image of the memory 4 and the image of the memory 6 and writes the obtained image into the memory 6. Next, the original image on the memory 1 is written through the image bus 7 into the memory 4, and the image arithmetic unit 5 obtains the sum of the image and the image written to the memory 6 and writes it into the memory 6.

Filed: 1988-03-30
Abstract: PURPOSE:To make the title device usable by a non-specified person by releasing and setting a door from and to its locked state by using the signal of a coin sensor and actuating a stamping machine after the door is locked. CONSTITUTION:In case a deliveryman inserts a coin through a coin inlet 3, a coin switch 8 detects the coin and a controller releases a door 2 from its locked state. When the delivery man closes the door 2 after he opens the door 2 and puts a baggage in a baggage putting section 6, the controller takes the AND of the signal indicating 'baggage is in' from a baggage sensor 13 and another signal indicating 'door is closed' from a door sensor 14 and locks the door 2.

Title: Illuminator
Inventor: MOMOSE YOSHIAKI
IPC: G02F1/13357
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To reduce flickers and unevenness of the distribution of brightness on the display surface of a liquid crystal display by applying a specific phase difference between AC outputs of driving means of plural fluorescent tubes. SOLUTION: This illuminator is provided with plural fluorescent tubes 5a, 5b and transformers 3a, 3b, driving circuits 2a, 2b and an oscillator tube 1a for supplying AC outputs to the plural fluorescent tubes 5a, 5b and a phase shifting circuit 6 for applying a prescribed phase difference between AC outputs of the oscillator tube 1a. This phase shifting circuit 6 is constituted of an operational amplifier OP2, resistors R21-R23 and s capacitor C21 and delays the voltage phase of an AC signal having an inputted frequency by 90 degrees to output it. Consequently, since phases of voltages to be impressed on the plural fluorescent tubes 5a, 5b are shifted, the fluorescent tubes 5a, 5b are lighted by shifting phases of lighting waveforms so as to cancel brightness and darkness with each other.  Since the phase difference is 90 degree, the difference between the maximum value and the minimum value of the sum of absolute values of respective AC voltages to be impressed on the tubes 5a, 5b becomes smallest and then brightness and darkness can effectively be canceled.
