Title: Production of briquette of chips
Inventor: OKADA YUJI
IPC: C22B1/248
Filed: 1995-02-17
Abstract: PURPOSE: To enable the reuse of metallic chips having no moisture and no oil content without oxidizing them by heating from the inner part with high-frequency induction current after press-forming the metallic chips and vaporizing the stuck moisture and oil contents. CONSTITUTION: The metallic powdery chips 1 easily oxidized is charged into a hopper 13 with a transporting means 12 and press-formed to make the briquettes 2 and the briquettes are charged into a vessel provided with a high-frequency induction coil 20 at the outside while shifting with a conveyor 15. Electric current is conducted to the coil 20 and the briquettes 2 are heated from the inner part with the induction current, and the moisture and the oil contents stuck to the chips are heated and vaporized to be left from the briquettes 2. The moisture becomes steam and the oil content becomes C and H by vaporization and decomposition, and C and H are reacted with O2 in the air and removed as CO2 and H2 O.  The O2 in the air at the outer periphery of the chip briquettes 2 are reduced by this reaction, and the chip briquettes 2 having no moisture and oil contents without being oxidized are recovered into a shipping cart 16 as non-oxidized chip briquettes 2.

IPC: H04L7/08
Filed: 1986-02-14
Abstract: PURPOSE:To decrease a frame synchronization restoring time by storing a data next to a decided data of an (n+1)-th frame in the n-th storage circuit. CONSTITUTION:Consecutive n-frame of consecutive (k+md-1)-th bit at each frame period are stored sequentially in the 1st - n-th storage circuits and data of a frame next to n-frame of consecutive k-bit are stored in the (n+1)-th storage circuit, the compared data of k-bit from the head of all the storage circuits and the standard frame synchronizing pattern are compared so as to decide whether or not they are coincident completely. When the decision is dissident, the compared data is shifted to repeat the decision and when no coincidence is obtained even with the decision up to (d) times, the storage data of the 2nd - n-th storage circuits are shifted to the storage circuit of the 1st - (n-1)-th storage circuits and the data of (d+1)-bit from the head of the frame stored in the (n+1)-th storage circuit is stored in the n-th storage circuit and the decision starts from the next frame.

IPC: H04B1/64
Filed: 1978-03-15
Abstract: PURPOSE: To restore input analog signal by reproducing level discrimination output with the reproduced range information and converting data to analog signal with this output.  
     CONSTITUTION: When an input analog signal is applied to input terminal 1, a sample holding amplifier 2 makes sample holding operation, by which the above input analog signal is sample-held. The sample-held signal is sent to a gain variable amplifier 3, but at this time the variable gain amplifier 3 is set at the minimum gain by the command from a level discrimination circuit 6 and the output signal from the amplifier 3 is setn to an analog-digital converter 5. This converter 5 is start-controlled  by the start pulse from a control signal generator 4. Here, if the range information is transmitted, the upper bits MSB may be created from this  range information and therefore there is no need for transmitting the MSB of the  data and MSB becomes also 1 when any of the range information is 1, thus only  required on the reproduction side is to add from the range information.

Filed: 1990-02-09
Abstract: PURPOSE:To automatically carry out an exposure which is properly complying with film exposing conditions by toning and shielding light from a white light source with respect to cyan, yellow and magenta through the use of each color correcting film. CONSTITUTION:Cyan, yellow and magenta correcting filters 8C, 8M, and 8Y are inserted into an optical path from the white light source only by a prescribed quantity by filter driving mechanisms 9C, 9M and 9Y respectively. Therefore, the light which passes through each color correcting filter obtains each tone and comes out. This light is diffused and mixed inside a light diffusing cylinder 3 at a subsequent stage, turned into a light beam of uniform and proper tone (normally standard white light), emitted on the part of the printed film 4 which is exposed. Then, when each quantity of each color component of the light exposing the film 4 reaches each proper quantity which is obtained according to the degree that the film 4 is exposed, each filter of the 8C, 8M and 8Y to shield the light of each color is inserted into the optical path in order. Thus, the exposure further properly complying with conditions for exposing the film 4 is easily carried out.
