Title: Compression of color data
Inventor: KONDO TETSUJIRO
IPC: G06F3/153
Filed: 1987-09-16
Abstract: PURPOSE: To attain efficient color compression by obtaining representative color compression data based upon the static characteristic of a picture in accordance with the gradation data of a color having a maximum gradation change between a current picture and its preceding picture. CONSTITUTION: Eight bits b0 to b7 or the like are allocated to one pixel read out from a display memory, the upper three bits 000, 010, 001 correspond to a control code and the lower five bits correspond to respective color gradation data (r), (g), (b). Then, thirty-two layer gradation faces G1 to G32 corresponding to the five bits are selected in accordance with the color data (g) e.g. having the maximum gradation change between a preceding pixel and a current pixel. The gradation data of these faces G1 to G32 are selected in accordance with control codes 011 to 110 consisting of the upper three bits registering five kinds of cubic areas 7 as compressed data in accordance with the static frequency.  When color data having the maximum gradation changes are (r) and (b), the compression method is similarly applied and gradation selection based upon look-up can be remarkably increased without increasing the capacity of a display memory, so that efficient compression can be executed and display near to natural colors based upon sufficiently large gradation can be obtained.

Abstract: PURPOSE:To reduce the power consumption for defrosting and to shorten the defrosting time by guiding a hot blast from a high-temperature chamber to a low-temperature chamber at the time of the defrosting. CONSTITUTION:For the defrosting, a test is interrupted and a heater 23, a cooler 32, and a heater 33 for temperature control are stopped; and opening/ closing dumpers 13, 14, 17, and 18 are closed and dumpers 27 and 29 and defrosting dumpers 37 and 39 are opened. Then an air blower 25 and an air blower 36 if necessary are put in operation. Consequently, the outside air is sucked into the high-temperature chamber 2 through an outside-air intake 26. This air is heated in the high-temperature chamber with its remaining heat. This air and the heat in the high-temperature chamber 2 pass through a by-pass 22 to enter the low-temperature chamber 3 through an air outlet 28, an air duct 41, and an air intake 40 and then strikes on the cooler 32 for the defrosting, and is exhausted from an outlet 38. Thus, the hot blast is supplied from the high-temperature chamber 2 to the low-temperature chamber 3 in the defrosting operation, so the temperature in the low-temperature chamber is raised speedily to complete the defrosting quickly.

Title: Finite impulse response filter
Inventor: OKAMOTO AKIRA
IPC: H03H17/02
Filed: 1992-08-31
Abstract: PURPOSE:To carry out a pulse code processing operation in a simple circuit constitution and with no complicated program required in order to calculate the response of a desired FIR (finite impulse response) filter after converting an analog signal having its amplitude varying continuously into a pulse code and then to convert again the pulse code into the analog signal. CONSTITUTION:The pulse codes following the shift registers 3-6 are successively inputted to a ROM 8 in the order of less significant digits via a 1st switch 7 of 7 bits, and the sum of a desired response and the more significant bit value of the address input is written in the ROM 8. Thus the ROM 8 can output the response of an FIR filter for the pulse codes by the superimpose theory while the switch 7 is outputting the most significant digit as long as the response preceding by one digit is inputted to the more significant bit of the address input.

Title: Method and device for radio communication
Inventor: OTSUKI SHINYA
IPC: H04L1/16
Filed: 1998-08-05
Abstract: PROBLEM TO BE SOLVED: To shorten a bit length required for a sequence number and to attain the reduction of fields by giving the same sequence number to plural packets in the same frame. SOLUTION: When one frame is to be composed of four packets, by giving the same sequence number to two packets in the same frame, the maximum sequence number required is reduced by half. At the time when one frame is received, the reception side returns a reception confirmation notice ACK or non-reception notice NCL to the transmission side. When any error occurs in the second packet of a sequence number '3' and also in the first packet of a sequence number '5', only the sequence numbers of such packets are returned as NCK to the transmission side. The transmission side sends two packets of the same sequence number again. In this case, since the packets to be given the same sequence number is limited to those in the same frame, the problem that the order of transmission becomes unclear on the reception side can be solved as well.
