Abstract: PURPOSE:To make the priority level of each interruption logic variable, by controlling an OR gate by the control code from a CPU in the interruption controlling system of the nesting structure. CONSTITUTION:When control codes A-C from a CPU are L, L, and L, contents of outputs (a)-(f) of a decoder 29 become H, L, L, L, L, and L, and as the result, outputs of OR gates 30, 33 and 35 become H, and outputs of OR gates 31, 32, 34, and 36-38 become L, and therefore, interruption priority levels are given to interruption logics 11, 12 and 13 in order. When control codes A-C are other values, the relation of interruption priority level among interruption logic 11-13 is varied. Consequently, interruption priority levels of plural interruption logics are varied by the control of the CPU.

Title: Mechanical-hydraulic closed forging press
Inventor: KAMIIDE TAKUO
IPC: B21J9/18
Filed: 1985-05-09
Abstract: PURPOSE:To obtain a double-action press having high utilization value for closed forging at a low cost by providing a pin for an inner slide to the center of a crank shaft and providing side eccentric bodies to both sides thereof to generate the die clamping force of an outer slide. CONSTITUTION:An oil pressure is generated on the right side of a piston 10 to eject a rod 9 and the piston 10 so that an upper link 3 and a lower link 6 are held stretched, thereby lowering the slide 8. The center of a knuckle pin 4 is held offset in this stage by the distance (e) from the straight line connecting the centers of the side eccentric bodies 2 and a gudgeon pin 7. The inner slide 15 makes the pressurizing operation by a punch when the crank shaft 1 is rotated. The side eccentric bodies 2 on both sides make the same rotation as the rotations of an inner crank pin 16 and the outer slide 8 is forced to descend to generate the die clamping force. The oil pressure is generated always on the left side of the piston 10 and therefore the outer slide 8 maintains the specified die clamping force. The punch of the inner slide 15 executes the molding work during this time.

Filed: 1994-05-11
Abstract: PURPOSE:To produce a gas sensor with high yield by disposing a gas detecting element and a temperature compensating element closely each other such that the temperature is distributed uniformly through thermal conduction among porous ceramics. CONSTITUTION:A gas detecting element 34A is bonded to a compensating element 33A through an inorganic adhesive.

When a temperature difference is present between the porous ceramics of the elements 34A, 33A, heat transfer takes place to substantially equalizing the temperature between them. Consequently, the electric resistance of the coils 31, 31 is sustained at an equal value. When a flammable gas is present in the atmosphere, combustion of gas takes place at the element 34A and the temperature thereof increases to cause imbalance. The temperature is eventually equalized through thermal conduction but the momentary temperature imbalance at the initial stage is detected based on the bridge output and an alarm is delivered from the sensor.

Abstract: PROBLEM TO BE SOLVED: To make it possible to minimize false-positive observation by imparting the color, which masks the original color of reaction product, to a water phase, when the result of the immuno-reaction in the water phase is evaluated by the visual observation of the colored reaction product collected on a collecting surface. SOLUTION: The water suspension, wherein both components of the marking component containing the coupled product of the first immuno-reaction material and coloring particles and the solid-phase component containing the coupled product of the second immuno-reaction material and solid-phase particles are mixed, is formed. In this liquid, the material to become analysis object, e.g. urine sample, is contained. These materials are coupled directly or indirectly as the function of the presence of the analysis object. The filtering and identifiable solid-phase complex including a coloring component is formed. The complex is collected on a filter element. The presence of the coloring component is evaluated by the visual test. The analysis object in the sample is detected.  In this case, the coloring material sufficient for masking the color of the coloring particles is contained in the suspension liquid. The color of the coloring material is removed from the collected complex. Thus, the minimizing of the faulse-positive effect can be performed.

Title: Synchronizing circuit for random code for spreading spectrum
Inventor: NAKAMURA TADASHI
IPC: H04J13/00
Filed: 1989-04-18
Abstract: PURPOSE:To quicken the establishment of synchronization by providing a shifter shifting a pseudo noise signal stored in advance. CONSTITUTION:A variable shift register 9 uses a reset signal Res generated at the same time as an input gate signal tw to decide a head code PN3 of a PN code generator 8, applies shift of bits to the code by a count output C of a counter 5 and outputs a pseudo random code PN4 synchronously with a spread input signal. An output of the variable shift register 9 is used to apply exclusive OR processing to the inputted spread signal with a spread demodulator 30, from which information data is outputted. Thus, the input spread signal is subject to inverse spread with an output of the variable shift register 9, and since the demodulated information data is coincident with the data of a sender and the pseudo random code PN4 being the synchronizing output is outputted directly from the variable shift register 9, much time is not required for generating an output.
