Patent JP-S55160867-A (JP)
Title: Underwater detector
Inventor: IINO HIROSHI
IPC: G01S7/34
Filed: 1979-05-18
Abstract: PURPOSE:To display a reception signal in respective directions uniformly by sample- holding a offset voltage of a detector to eliminate itself during a pause time just before a transmitting pulse is emitted. CONSTITUTION:When a normally open switch SW12 conducts across an input and an output, a normally closed switch SW11 is cut off across the input and the output. Accordingly the holding circuit C1 holds a detection voltage at the time no signal is given to the input of the detector D1, that is, the offset voltage of the detector D1. The held voltage by the holding circuit C1 is applied to one terminal, of an adder AD1, and it acts so that the output voltage of the detector D1 may be eliminated. Namely the output voltage of the detector D1 is negatively fed back by the output voltage of the holding circuit C1.

Title: Method and device for recording image and communication device with the same device
IPC: H04N1/23
Filed: 1992-03-18
Abstract: PURPOSE:To prevent the generation of white stripes, etc., generated when recording time intervals are lengthened, and to improve the recording grade of an image by conducting electcity and performing recording to a recording head while being delayed from the start of the conveyance of a recording medium when time intervals indicating printing start reach a fixed time or more. CONSTITUTION:The temperature rise characteristics of the heating resistor of a thermal head 202 are improved so as not to delay printing timing to the trigger of a motor 21 for paper-feed in a first section, in which one block is printed. Consequently, when the first section, in which one block is printed, is printed, the deterioration of recording image quality by the lowering of the color-developing density of recording paper due to the over-drop of the temperature of the heating resistor is improved. When the time intervals of printing timing are lengthened in a facsimile device, a strobe signal continues to transmit over the thermal head 202 for a certain fixed time within the time intervals of printing timing after normal printing.

Abstract: PURPOSE:To distinguish the image of the uppermost cargo from the image of other cargoes through a simple and quick process and, at the same time, to find the position of the centroid of the upper surface shape of the uppermost cargo through a simple process. CONSTITUTION:The title method contains a process D for obtaining the spatial code image of a whole cargo and another process E for extracting the image of the uppermost cargo W.

The measuring space of the cargo W is divided into superposed wedge-like measuring areas r0-rn and a spatial code is set to each measuring area r0-rn. A spatial code image containing a spatial code is obtained against each picture element value of the image taken with a camera 3. The extraction of the image of the uppermost cargo is performed by only leaving picture elements containing spatial codes lower than a specific value from the spatial codes representing the wedge-like area having the maximum angle at every horizontal picture element row of the spatial code image of the whole cargo. Cargoes are ground (F) at every kind and the transforming point of each side is extracted at every group (G), and then, each point is transformed into three-dimensional coordinates (H). The position G of centroid on the projected surface and inclination theta in the X-Y plane are found (I) and the height to the upper surface of cargo is obtained (J).
