Title: Manufacture of extruded board with pattern
Inventor: OTAKI KUNIHIKO
IPC: B29C47/00
Filed: 1990-05-28
Abstract: PURPOSE:To easily obtain an extruded board with patterns by feeding dye and pigment or resin containing dye and pigment to a second feed section of a two-stage screw extruder. CONSTITUTION:The first object of a first stage 5 is to plasticize and knead a resin, whereas, in a second stage 9, pressure is made zero in a second feed section 11 to effect venting, thereafter the pressure is raised in a second compres sion section 12 and the resin is metered in a second metering section 13. When the resin is fed into the stage 9, the resin is in a molten state and kneading is not required and hence kneading capacity can be made smaller. If dye and pigment or resin containing dye and pigment is fed into the section 11 through a vent hole 10, extrusion can be performed, while dye and pigment, and resin are insufficiently kneaded. A T-die 14 is placed at the end of an extruder so that the resin to extruded in the form of plate. For example, if a three-roll type cooling roll 15 is employed to cool and polish resin, an extruded board with patterns on its surface can be produced.

The external surface of the heat transfer tube 3 in the flow passage is covered with a refractory material 4 so as not to be brought into direct contact with the hot exhaust gas. The air flowing in the heat transfer tube 3 in the flow passage absorbs and recovers the heat of the hot exhaust gas G2. The external wall 10 is provided with a refractory wall 13 provided on the side opposite to the hot exhaust gas G2 and a metallic heat transfer tube 11 outside the flow passage arranged over approximately whole outer circumferential surface of the refractory wall 13.  Water flows in the heat transfer tube 11 outside the flow passage as the thermal medium to absorb and recover the heat of the hot exhaust gas G2 in water.

IPC: H04L25/03
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To correct the effect of a phase error even under the environment of frequency selective multi-path fading in a radio data communication terminal adopting the method where a transmission line characteristic is found for a preamble period by the narrow band modulation system so as to equalize a received signal. SOLUTION: An equalizer 14 finds a characteristic of a transmission line, a value of a tap coefficient found by the characteristic of the transmission line is set to the equalizer 14 and a replica signal generating section 15 to start demodulation of data by the equalizer 14. Demodulated data are sequentially given to the replica signal generating section 15 and I/Q signal components (the real number amplitude and the imaginary number amplitude) received by the equalizer 14 are reproduced by using demodulated data and the tap coefficient. A phase difference detection section 17 finds a phase difference between the reproduced I/Q signal component and the I/Q signal component subject to timing adjustment before entering the equalizer 14. A division section 18 conducts optional weighting.  An integration circuit 19 integrates the phase difference in the unit of symbols, a vector conversion section 20 converts the output of the integration circuit into a reception signal component, which is fed to a phase rotation section 13 to correct the phase error.

Title: Branch instruction prefetch system
Inventor: AKAGI MASANOBU
IPC: G06F9/38
Filed: 1980-09-29
Abstract: PURPOSE:To prefetch a branch instruction by forecasting the prefetch, by holding branch direction information in a branch direction control memory having the same structure with a buffer memory. CONSTITUTION:The tendency that an optional branch instruction executed several times is branched frequently in the same direction every time it is executed is utilized to store its branch direction, determined in the execution of the branch instruction, in a branch direction control memory 20 every time the instruction is executed. Prior to the execution, the instruction, where prefetched from a buffer memory 40 is prefetched by considering the possibility of branch in the same direction as before to be high. A prefetch control part 10 considers the possibility of branch in the same direction as before to be high according to the contents of a branch direction register 70 indicating the branch direction (success or failure) when the same branch instruction is executed, thus prefetching the instruction.

Abstract: PURPOSE:To make it easy to reduce the diameter of a wing pit so as to prevent clogging with sludge by projecting the end portion of the wing bit inwards to form projecting portions that overlap each other when the diameter of the bit is reduced, and tilting their opposite surfaces, and providing a reverse water hole. CONSTITUTION:Water and air, etc., are fed forward through water holes 6a, 17a and are fed to a forward bit from the water hole 32 of a head stem 12 and discharged forward from the water holes, and a part of them is discharged backward into a steel pipe from a reverse discharge opening 40 to discharge sludge in the steel pipe. When a drilling rod is retreated, the head stem 12 is moved relatively to a sleeve 13 and a wing bit 21 and a projecting surface 21b is moved out of contact with the outer surface of the head stem 12 and a guide protrusion 25 is withdrawn behind a projecting portion 23; therefore, the wing bit 21, pushed inward by the end portion of the steel pipe 10 or the like, sinks into a storage portion 19. The wing bit is quickly enclosed because the clearance angle (alpha) of its outer surface is as large as 25 to 40 degrees. When the diameter of the wing bit is reduced, the diameter of an entire drilling portion 7 becomes smaller than the bore of the steel pipe 10.

Abstract: PURPOSE:To avoid waste of consumed power at the time of non-employment of the device by enabling breaking of a power source when a prescribed time passes after a timer is started in the calorie balance which is capable of indicating the calorie of an article. CONSTITUTION:When the device is not operated for twenty minutes from the time when a start key of a key board 21 is charged, a microprocessor 50 switches a high- level signal for the base of a transistor 38 to a low-level signal and thereby a cell 31 is separated. When a weighing operation is conducted during these twenty minutes, a true-value weight register MTRU turns greater than zero, and when a key input is conducted during this period, a time memory MT is re-set, conducting recounting. And, when a state of weighing is left as it is for twenty minutes from re-staring of a timer or when no subsequent key input is conducted, the processor 50 switches the high-level signal for the base of the transistor 38 to the low-level signal, separating the cell 31 also in this case.
