Title: Scroll type compressor
Inventor: SUZUKI SHINICHI
IPC: F01C1/02
Filed: 1988-07-18
Abstract: PURPOSE:To avoid breakage of an end terminal without the thinning of thickness by making a cutting path along an inner wall surface in the side of the end terminal a curve diverted gradually from an extended line of an involute curve. CONSTITUTION:An external wall surface 3a of a spiral part 3 formed upright in a basic terminal wall 2 of a fixed scroll 1 intersects with a circumference C1 of a radius R of the basic terminal wall 2 at an end terminal 3', and it is so formed that the end terminal 3' of the spiral part 3 which ranges from an intersection P1 of the circumference C1 and the external wall surface 3a to a starting point becomes gradually thinner compared to the other portions. At the end terminal 3, more than the escaping amount of the thin wall is absorbed by the diverting amount, through the shifting of an end mill along a cutting path that is gradually diverted outside of the involute curve, and the trespassing of the inner wall surface behind the back of the thin wall to the inside of the involute curve is thus avoided.

Title: Character detecting and cutting method
Inventor: OOTA NAOKI
IPC: G06V30/148
Filed: 1980-12-17
Abstract: PURPOSE: To easily execute the character recognition processing after the character has been detected and cut, by fetching a necessary character information from the character information formed in blocks, in accordance with a sort of an address character information and cutting the character.  
     CONSTITUTION: Projection mask data M 1 , M 2  in both the longitudinal and lateral directions as to each character are generated by a pattern signal from a photoelectric conversion part, and in accordance with said data, detecting and cutting characters are classified into each block. By classifying into blocks, whether an interval between character masks M, M is too away or not is decided, and the interval between blocks is decided. Subsequently, the block is divided by deciding that a comma 10 and a period 11 are present between the blocks. Subsequently, the block formation is executed by deciding the height H of the mask M. The address information is formed in blocks by one of these method or combining them, this character formed in blocks is cut one by one, is transferred to a character recognition part together with the block information, and the character is recognized.

Filed: 1984-08-28
Abstract: PURPOSE:To decrease the number of connector pins and the number of cable cores by providing a two-way driver receiver control circuit which controls to turn on or off the driver receiver for every two-way driver receiver. CONSTITUTION:When a computer 1 receives the data from I/O3, a data transfer request is sent to an address bus 7 and a control bus 6. Thus, a two-way driver receiver control circuit 10-2 designates the conductive direction of a two-way driver receiver 5-2 to data buses 8-3 8-2 8-1, the data are transferred in this direction and inputted to the computer 1. Namely, input data of two-way drivers 5-1 and 5-2 are monitored, and if all bits of the input data do not be a prescribed value (for example, ''1''), it is judged that the data exist which should be transferred to the next step two-way driver receiver. As the result, an output of the two-way receiver is controlled successively to an on condition and the data are successively transferred. Thus, a selecting line is made unnecessary and the number of connectors and the number of cores can be decreased.
