Title: Image reconstruction system
Inventor: YAMADA KAZUYA
IPC: A61B5/055
Filed: 1989-04-14
Abstract: PURPOSE:To simplify the circuit constitution of an arithmetic part by mutually cascade-connecting plural BP blocks and executing the pipeline parallel processing and accumulative addition of the same lines of different projections to execute the multiplex processing of BP interpolating operation. CONSTITUTION:Respective back projection(BP) blocks 6 are mutually cascade- connected and a BP operation part 4 executes the pipeline parallel processing and accumulative addition of the same lines of different projections to execute multiplex processing. Since the BP multiplexing direction coincides with the projection direction, a local memory to be connected to the post stage of the BP operation part 4 can be omitted, and since the same BPs are set up in different lines, storage capacity for one projection is sufficient for a back projection input memory(BIM) 7. Consequently, the operation part 4 can be simply constituted.

Title: Bus control system
Inventor: KAWAI TAKUJI
IPC: G06F13/00
Filed: 1990-04-11
Abstract: PURPOSE:To prevent the malfunctions of other units connected to a bus which are caused by the noises produced by the loading/unloading actions of a stop cock by inhibiting the grant of the bus right in a transient state set when the stop cock of a unit is loaded and unloaded. CONSTITUTION:The transient state detection mechanisms 3a - 3c provided opposite to the loadable/unloadable units 1a - 1c and a part of a control unit 2 detect that the units 1a - 1c are loaded to and unloaded from a common bus via a stop cock and give the detecting results to a bus right control mecha nism 4. The mechanism 4 inhibits the grant of the bus right to other units during the reception of the detection signals. Therefore the common bus becomes unavailable for the time being. Thus it is possible to prevent such a defective case where the noises are transmitted to the common bus due to the loading/ unloading operations of the units to the common bus causing malfunctioning of other units.

Title: Anti-skid controller
Inventor: YASUNO YOSHIKI
IPC: B60T8/66
Filed: 1987-04-16
Abstract: PURPOSE:To make it possible to calculate suitable estimated vehicle speed approximate to real vehicle speed despite braking at the time of going forward or backward by calculating through integration the absolute value of a detected value from a front/rear direction acceleration detecting means by the use of an estimated vehicle speed operating means. CONSTITUTION:When braking is started and a brake switch 1 is turned ON, an integrator 52 holds wheel speed Vw at that time as ran initial value. And, a front/rear G sensor 2 outputs a detected value alpha indicating deceleration at the time of going forward, so that an absolute value outputting circuit 51 feeds out the value alpha as it is to the integrator 52. And next, the integrator 52 integrates the output signal from the circuit 51 so as to obtain estimated vehicle speed Vi, thereby feeding it out as a signal to a liquid pressure controller 6, and moreover, the controller 6 outputs a control signal C for increasing, holding or decreasing a pressure to an actuator 7. And further, in the case of braking at the time of going backward, the sensor 2 outputs another detected value -alphaindicating acceleration at the time of going backward, so that the circuit 51 converts its negative sign in order to obtain its absolute value, and then feeds out the value alpha to the controller 6 via the integrator 52.

Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To make possible imparting a natural delay vibrato effect without enlarging capacity a calculating buffer. SOLUTION: A delay vibrato calculation part 12 calculates a vibrato waveform until a delay vibrato arrives at a stationary state of a fixed depth. On the other hand, in the stationary state, the delay vibrato calculation part 12 is released, and the vibrato waveform by the fixed depth stored in a delay vibrato information storage part 11 is outputted. Then, the delay vibrato generated after the calculation part 12 is released is made a perfect waveform based on calculation. Further, since the later departed delay vibrato generated until arriving at the stationary state is generated using storage contents in a calculation result storage part 14, the calculating buffer for this later departed delay vibrato is omitted.

Title: Variable stator blade for use in turbo-machine
Inventor: TSUJIMURA KUROTAKA
IPC: F01D17/16
Filed: 1978-08-04
Abstract: PURPOSE: To prevent leakage of fluid through the gap between opposite end portions of stator blade and inner and outer rings, by employing an arrangement in which a small plate in the form of a leaf spring is fixed at one end thereof to the opposite ends of stator blade along the entire width thereof and the other end of the small plate is slidable along the inner and the outer rings of the stator blades.  
     CONSTITUTION: A small plate in the form of a leaf spring 32 is welded to one end of stator blade 30 at welding portion 321, and natural height C' 1  of the small plate 32 is made slightly larger than the small gap C 1  formed between the top of stator blade 30 and inner ring 10, the height of small plate 32 becomes C 1  when the stator blade is assembled in place. Therefore, when assembling of these stator blades is completed, one end of the small plate 32 is held in contact with the wall surface of inner ring 10, thereby minimizing the gap substantially. Further, in the arrangement of this invention, the small plate 32 is welded to stator blade 30 on the side of back surface 30B, so that small plate 32 is still more urged onto the wall surface of inner ring 30 since pressure of working fluid during operation is higher on the front side 30A than back side 30B of stator blade 30. By thus eliminating leakage of working fluid to the side of back surface 30B, turbine efficiency can be improved considerably.
