Title: Interruption integrating device
Inventor: SAKURA OSAMU
IPC: G06F13/24
Filed: 1987-03-10
Abstract: PURPOSE:To reduce the load of a CPU by outputting an interruption integrating signal in accordance with the formation of an AND condition between an output from a state change register and an output from a timer device and initializing the state change register and the timer device. CONSTITUTION:At the time of generating a state change, the state change register 15 temporarily stores an interruption signal outputted from a DMA 6 and outputs the existence of the interruption signal to an AND circuit 17. On the other hand, the timer device 16 outputs an authorized signal to the AND circuit 17 after the passage of a prescribed time from its initial state. When a state change is generated after the passage of the prescribed time from the generation of the preceding interruption signal, the interruption signal is outputted to a state change receiving device 13 as it is, and at the time of generating the initial interruption signal after the passage of the prescribed time from the generation of the preceding interruption integrating signal in case of multiplex state change, only the initial interruption signal is outputted to the state change receiving device as it is and the succeeding interruption signals are multiplexed by the state change register and collectively outputted after the passage of a prescribed time.

Filed: 1980-04-23
Abstract: PURPOSE: To convey a work intermittently at a fixed pitch with an intermittently conveying apparatus which is designed to accomplish a rapid speed adjusting- stopping control based on any speed adjusting characteristics being preset.  
     CONSTITUTION: A work W is positioned and placed on a platen 11 by way of an attachment 4. A motor 17 is started while a clutch brake unit 18 is turned on and connected to an index unit 19 to be driven. This converts the angle of turning during the rotation to a speed adjusting characteristic set at the speed adjusting area and the rotation stopping area as indicated by a mark V in the drawing B. The output shaft 19' is rotated and the rotary motion is turned to a straight motion through a ball screw section 37 of a main shaft 36 and a ball 41 and transmitted to a platen 13 through a ball holder 40. Thus, a platen 13 moves along guide rails 11 and 12 and the work W being placed is halted at the rotation stopping area to be machine worked.

Abstract: PURPOSE:To stably and economically obtain an electrodeposition-coated article having excellent corrosion resistance especially at its edge by coating a material with an electrodeposition paint added with a porous fine-powder filler, and then cross-linking the paint by heating. CONSTITUTION:A material to be coated is dipped in the electrodeposition paint, coated, and integrated with the paint by the resin in the coating film and the resin infiltrating into the porous fine-powder filler. Accordingly, the flat part and edge of the material are uniformly coated with the paint to form a composite coating film. The composite coating film is then heated, and cross-linked to obtain an electrodeposition-coated article having excellent corrosion resistance especially at its edge. An inorg. or org. filler having >=80 deg.C, or preferably >=100 deg.C, softening point is appropriately used as the porous filler, and the inorg. filler is preferably used because its softening point is remarkably higher.

CONSTITUTION:When jewels are discharged from a vibration transfer device 4, they slide on an inclined plate 5 to be horizontally transferred toward the terminal of a belt conveyor 6 by the belt conveyor 6. The jewels reaching the terminal of the belt conveyor 6 fall in the weighing hopper 3 of a wt. meter 2. When the measured value of each of the jewels is read by a control microcomputer, a feed tube transfer apparatus 13 moves a feed tube 12 so that the discharge port of the feed tube 12 comes to the position directly above the jewel receiving box 10 of a classifying shelf 19 predetermined corresponding to the measured result to position the discharge port of the tube 12. Subsequently, the air in the feed tube 12 is sucked and discharged to feed each of the jewels to the net 22 provided in the vicinity of the discharge port and suction is stopped to allow the jewels to fall in the receiving box 10 to automatically classify the same.

As an antiCM-Hb antibody, a specific antibody to recognize CM-Hb may be a monoclonal antibody to recognize a specific portion or a polyclonal antibody to recognize any portion. A carboxymethylated human serum albumin antibody, etc., to react strongly with only CM-Hb are used from the point of the detection sensitivity of CM-Hb. An immunoagglutination method can be adopted as a method to measure CM-Hb through the use of a CM-Hb antibody. As a specific qualitative method, a latex agglutination method, microtiter method, etc., can be adopted, and a latex quantitative method, etc., can be adopted as a qualitative measuring method.  A hemotytic solution prepared by mixing blood with the aqueous solution of a non-ionic surface active agent with hydrophilicity and hydrophobicity of 10-17 is used as a measurement sample.

Abstract: PURPOSE: To make it possible to stabilize an operating characteristic of a contact spring which is driven through a crank, and to improve its operational property, by making a contact part of a push-button and a crank, a point contact structure.  
     CONSTITUTION: When an external force is put to a push-button 6 from the upper direction with a finger, etc., the push-button is depressed downward. This force is transmitted to a crank 2, holding a point contact state between a driving contact part 6a of the push-button and the cylindrical crank 2 which is disposed intersectionally and face to face with the aforesaid driving contact part 6a, is changed into a rotary operation by a fixed shaft 2a, and drives and controls a common contact group. Accordingly, even if the push-button is depressed in a state that it is slightly inclined, there is no movement of a contact point and there is little influence on a rotary operation of the crank 2, owing to a point contact state.

Abstract: PURPOSE:To set an optimum recording laser intensity at the time of irradiating a recording medium with laser to write a signal. CONSTITUTION:The laser intensity is modulated in a laser driving circuit 4 by the signal obtained by adding signals having a frequency f1 and a lower frequency f2 in a means 3, and the laser intensity is stepwise changed to record the addition signal on a recording medium 6, and the recorded signal is reproduced, and the recording laser intensity is set to such laser intensity by a laser output setting circuit 5 that the level of f1-f2 or f1+f2 is minimized with respect to relation between the laser intensity and the output of a level detector 11 which detects the level of f1-f2 or f1+f2. Thus, the optimum recording laser intensity is always set independently of the variance in recording sensitivity of the recording medium, the temperature detection precision of the recording medium, and the initialization precision of the laser intensity.
