Title: Data compression circuit, data expansion circuit and motion compensation prediction decoder
Inventor: HATANO YOSHIKO
IPC: H04N19/126
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive motion compensation prediction decoder requiring less memory by providing an encoding circuit for blocking pictures every plural picture element and encoding them for respective blocks, the memory for storing the encoded blocks and a means for storing the head addresses of the blocks on the memory. SOLUTION: An inputted bit stream is variable length decoded in a variable length decoder 21 and an encoded prediction error, a prediction mode and a motion vector are outputted from the variable length decoder 21. The encoded prediction error is decoded by an inverse quantizer 22 and an inverse DCT transformer 23 and added to prediction pictures outputted from a prediction picture preparation circuit 26 in an adder 24. The pictures outputted from the adder 24 are the decoded pictures and a data compression circuit 104 compresses and stores the pictures. Since the adder 24 outputs the decoded pictures in an encoding order, the data compression circuit 104 rearranges compressed data in a display order and outputs them. A first data expansion circuit 105a expands the output and outputs the pictures.

Title: Forming apparatus and method of electrode plate for lead storage battery
Inventor: YAMANA TAKUMI
IPC: H01M4/22
Filed: 1979-05-29
Abstract: PURPOSE:To form a conductor with a connecting lever without the needs to connect them by welding by a procedure in which plural unformed electrode plates are assembled into one block and their lug portions are placed on plate hangers provided with alternately arraged concavities of different depths. CONSTITUTION:The plate hangers A and B placed on both sides of a forming tank are formed by combining the plate hangers 2 made of a comb-shaped lead alloy with plurally arranged concavities 3 with the plate hangers 4 made of a comb- shaped synthetic resin with alternately arranged concavities 5 and 5' of different heights. And, the lug portions 7 and 7' of a block of the plural unformed plates 6 are placed on the concavities 3, 5, and 5' to form a forming device. Thus, because no conductor is formed where the lug portion comes into contact with the shallow concavity 5, whereas a conductor is formed where the lug portion comes into contact with the deep concavity 5, the contact between the unformed plates can be formed simply by placing the lug portions on the concavities, permitting inefficient welding operations to be eliminated.

Filed: 1985-03-30
Abstract: PURPOSE:To pass an original through a confirmation part with an original cover closed and to confirm the setting state of the original by providing the original cover with the confirmation part which allows an indicating means to be confirmed visually. CONSTITUTION:The original cover 17 has a scale 25 as the confirmation part and a see-through window 27 of such size that an indicator lamp 26 is exposed to the outside.

Namely, the relative position relation between the scale 25 and original is viewed through the see-through window 27 to confirm whether the original is arranged properly or not. Consequently, even when the original is covered with the original cover, it is easily confirmed at any time whether or not the original is set within a proper range.

Title: System for room cooling and snow melting
Inventor: OSHITA KAZUYOSHI
IPC: E04H9/16
Filed: 1985-03-29
Abstract: PURPOSE:To attempt cooling of a building and melting of the snow by connecting a slit pipe which has slits on both sides and a partition wall in the center to a duct and arranging the duct at right angle to the tile ledge. CONSTITUTION:When the ventilation opening of an air shutter 6 is opened and an intermediate ventilation fan 4 is driven, the air in the space 7 under the small roof flows to a slit pipe 2 through an intermediate ventilation fan 5, ventilation opening, intermediate ventilation fan 4, heat-insulation duct 3, and duct 41. Because the ends of the slit pipe 2 are covered with caps 14, the air exits uniformly through the whole slits 8. During summer day time the hot air in the space 7 under the small roof is exhausted to outside, and for room cooling the switch of the intermediate ventilation fan 4 is changed over to drive the intermediate ventilation fan 5, and the cool air made under the roof tiles 1 is drawn into the space 7 under the small roof to cool the whole building. In winter, a slide shutter 21 shuts off the air flow by closing the ventilation openings 19 and 20. In areas where snow accumulates, the heat in the building is transmitted to snow through the roof tiles 1 to melt the snow.

Abstract: PURPOSE:To prevent the occurrence of a trouble in which a device is rendered inoperative due to a freeze, by providing a driver circuit which actuates an alarming device, when a park signal, a door opening signal, and a freeze estimating signal are present together. CONSTITUTION:The electric potential of a first gate 1 of an AND gate AND is maintained between a plus electric potential and an earth electric potential during closing of a parking sensor PS.

When a driver opens a door, a door opening signal is sent to a second gate 2, and while the door is opened, the electric potential of a second gate is left in a state to produce an earth electric potential. An outside air temperature or a road surface temperature is measured by a temperature sensor TS, and meanwhile, a switching circuit HSC with hysteresis outputs a signal by means of which, when temperature exceeds a estimating freezing value, the electric potential of a third gate 3 produces a plus electric potential, and when below the estimating freezing value, the electric potential produces an earth electric potential. As noted above, when signals to the first gate - the third gate are present together, an output signal from the AND is sent to a drive circuit DC to actuate an alarming device WB.
