IPC: F24H1/18
Filed: 1993-12-16
Abstract: PURPOSE:To make a controller applicable in common to the control of a plurality of electric water heaters of different models by a method wherein the power supply to the electric heaters is turned on after an elapse of a specific peak-shift time from the start time of midnight power supply and the power supply to the heaters is turned off when the temperature of the water has reached a set heated point. CONSTITUTION:The power source is turned on when time comes for the midnight power supply. At this point a heating operation control part acts (ST1) and does an initial process (ST2). Next by inputting the water temperature detected by a control sensor THc (ST3) and using the detected value (temperature of feedwater Wt) a peak-shift time H in minutes is calculated (STY) according to an equation H=480-C.(T-Wt), wherein C is a constant. After an elapse of this peak-shift time (ST5) the power supply to the electric heaters is tuned on (ST6). When the temperature of water in the hot-water storage tank has reached a set heated point (ST7), the power to the heaters is cut off (ST8).

Title: Digital time base corrector
Inventor: OTAKI HIROSHI
IPC: H04N9/896
Filed: 1993-12-16
Abstract: PURPOSE:To reduce the storage capacity of a memory to nearly image data of about 1H while keeping an interleave relation between a luminance signal and a chrominance signal of a video signal. CONSTITUTION:This corrector is provided with an image data memory 11 storing image data corresponding to polarity data representing the polarity of a burst signal generated for each 1H, and a latch means latching the image data and the polarity data from the memory 11 and a subcarrier phase memory 17 for the data read period. When a dropout takes place in a video signal, the write of the image data and polarity data to the image data memory 11 and the subcarrier phase memory 17 is inhibited, and when the unmatch between the read polarity data and the polarity data latched by the latch means is detected, the color phase of the read image data is inverted. Thus, the storage capacity of the memory is reduced to nearly 1H of the image data while keeping the interleave relation between the luminance signal and the chrominance signal of the video signal and then the cost is reduced.

Abstract: PURPOSE:To output a character in a state that the type of said character can be easily identified by dividing a printing area of said character into a plurality of groups, deciding the position of said printing area and a non-image area on coordinates determined by the difference from a reference point from an adjacent printing area or non-image area, and storing data related to the priority when said printing area and non-image area are quantized and corrected. CONSTITUTION:In forming pattern data of a character, a printing area of the character is divided into a plurality of groups, for example, a group mainly composed of printing areas in an X axis direction and a group mainly composed of printing areas in a Y axis direction, etc. The position of each of the printing areas and non-image areas in the group is specifically determined on coordinates set by the difference from a reference point of an adjacent printing area or non-image area. Data related to the printing area and non-image area are respectively added with data related to the priority in quantization and correction. In other words, the priority of the printing area or non-image area which is less influenced on identification of the type of the character even by the quantization and correction is set higher, while the printing area or non-image area which is greatly influenced on the identification of the character by the quantization and correction is arranged to have a lower priority. If a character is outputted on the basis of the data formed in the above-described manner, even when it is outputted by reduced member of pixels, it can be outputted in such manner that the type of the character is easily identified.
