Title: Method for deciding manipulated variable saturation in closed loop system
Inventor: NISHINO TAKUSHIROU
IPC: G05B23/02
Filed: 1987-04-14
Abstract: PURPOSE:To easily decide manipulated variable saturation by modeling the dynamic characteristic to obtain a transfer function and setting a desired target characteristic in accordance with this function to obtain the characteristic between a target value and a manipulated variable. CONSTITUTION:A control object 1 consists of a servo amplifier 11, a servo valve 12, an inertia load 13, and a detecting part 14. For the purpose of deciding saturation of a manipulated variable (u) from a controller 2, the dynamic characteristic of the control object is modeled to obtain the transfer function. A desired target characteristic is set, and relations between the target value and the manipulated variable are obtained to deciding saturation of the manipulated variable. Finally, the target characteristic of the controller 2 is set. Since the limit of an already provided actuator is made clear immediately after decision of saturation of the manipulated variable, the man-hour is reduced even if it is necessary to change the actuator capability.

Title: Vertical synchronizing signal separator circuit
Inventor: KANEKO ATSUSHI
IPC: H04N5/10
Filed: 1988-04-15
Abstract: PURPOSE:To obtain a stable horizontal synchronizing signal by providing a level deciding means which decides the level of the composite synchronizing signal when the pulse of the output of a second pulse generating means is completed, and triggering a first pulse generating means based on the decision result of the means. CONSTITUTION:A second non-triggerable mono-multi vibrator MMV2 has a composite synchronizing signal whose synchronization is positive polarity as a trigger input, and its pulse width is set shorter than the synchronizing pulse width of the composite synchronizing signal. An MMV1 is triggered by the rise edge of the output of an AND gate 3, and its pulse width is set at >=1/2H and <1H. Thus, adverse effect given by a noise at a time t1 to a horizontal synchronizing signal output does not exist. For the noise at a time t2, when the MMV2 and a noise pulse width are set at W1 and W2, and the synchronizing pulse width of the composite synchronizing signal is set at W3, the pulse width W1 of the MMV2 is set at the conditions of W2<W1<W3. Thus, the noise is eliminated by the AND gate 3, and does not affect the MMV1.

Filed: 1986-04-21
Abstract: PURPOSE:To obtain a cooking apparatus capable of automatically cooking delicious foods by making it possible to correctly detect a boiling point, deceas ing the amount of heating after boiling to prevent the cooked food from boil collapsing, and stopping heating before run-out of soup and scorching. CONSTITUTION:The measurement of temperature is performed every five seconds by a temperature rising rate measuring circuit 7. When the temperature rise value during that time is within 0.2 deg.C, a balanced temperature judging circuit 8 judges that it represents boiling. A temperature T1 is stored in the microcomputer of a control circuit 5. Further, immediately after boiling, the motor of a heating capacity controller 6 rotates based on a signal from a temperature lowering circuit 9 to throttle a cock and to lower the heating capacity, thus controlling the heating capacity so that a temp, measuement is held at constant temperature T2 which is lower by 2 deg.C than the boiling point. Thereafter, when the temperature is raised after a boiling down temperature to 17 deg.C, the motor of the thermal power controller 6 rotates to close the cock and thus combustion is stopped.

Abstract: PURPOSE:To obtain a flexible optical fiber with long life by providing acid-resistant coating on the edge of a bundle of threelayer optical fibers comprising core glass, acid-resistant glass and acid-soluble borosilicate glass and by treating, after bringing the whole into contact with acid, with an alkaline solution above specified pH. CONSTITUTION:In production of an optical fiber bundle where an edge 23 is adhered and the other part 25 is flexible, optical fibers 1 are bundled where glass 3 that is low in refractive index and is resistive to acid, is coated on the outer circumference of core glass 2 with a higher reflactive index, and further on the outer circumference, acid-soluble borosilicate glass 4 is coated. Acid-soluble glass 4 which is in the intermediate part is eluted and washed by immersing this fiber bundle 17 into a acid-eluting tank 21 and treating, for example, in 1 N nitric acie at 70 deg.C for about 2 hours. Next, the washed fiber bundle is treated in an alkaline solution of >=9 (for example, NaOH solution of 13.8pH) and the insoluble residue cinsisting essentially  of silica gel remaining in the vicinity of the edge 20 is eluted to be removed. The  edge 20 of a hard opeical fiber bundle 17 is coated with acid-resistive resin. The  fiber bundle 17 is removed with elution. Thus a flexible optical fiber bundle that has good durability and is short in length of the adhered part 23 can be obtained.

Abstract: PURPOSE:To prevent the sudden sinking during the braking operation by mounting at least two damping valves in parallel on a base plate secured to the upper part of an outer tube, and operating one of the two damping valves in linkage with the braking operation. CONSTITUTION:At the time compressing operation where an inner tube 2 moves in compressing suspension springs 7 and 8, the working oil within an oil chamber B flows into an oil chamber C through a check valve or the like formed in a piston 3. Surplus oil corresponding to the entering part of the inner tube 2 flows to an oil chamber A while pushing open the first damping valve 9 having an annular leaf valve 9A and the second damping valve 10 having a cylindrical valve 12. Accordingly, a weak damping force is obtained, upon this occasion. On the other hand, at the time of braking, an operating rod 16 is pulled upwards and a throttle valve 15 is seated on a valve seat 18, and hence communication passageways 14A and 14B are interrupted of the communication with the oil chamber A regardless of opening or closing of the damping valve 10, and a strong damping force is obtained.

Filed: 1989-04-14
Abstract: PURPOSE:To obtain heat energy which is generated by room-temperature nuclear fusion by a simple device by absorbing heavy hydrogen by a material applied with a negative voltage in vapor phase and causing nuclear fusion reaction between heavy hydrogen atoms. CONSTITUTION:Heavy hydrogen gas 1 is admitted to a vacuum container 3 through a variable leak valve 2 to cause dissociation and adsorption on the surface of a base material 5. The dissociated and adsorbed heavy hydrogen enters a below-surface state by surface reconstitution and is diffused inside gradually. After the heavy hydrogen is absorbed sufficiently, a voltage is applied to the base material 5 from a power source 8 so that the base material is negative as compared with a grounded electrode. Nuclear fusion reaction is caused in the base material 5 to generate heat. Its heat energy is conducted out of cooling agent piping 4 using water, gaseous helium, etc. Helium and tritium which are produced by the nuclear and reaction and nonreacting heavy hydrogen gas is discharged by a discharge pump 11.

Filed: 1979-07-21
Abstract: PURPOSE: To simply prevent heat dissipation during the fire extinguishment at a circulation type bath furnace, by shutting off a circulation pipe throughout the fire extinguishment.  
     CONSTITUTION: A check valve comprising a valve element 7, a spring 8 and a spring fixation plate 9 is installed near the blowoff baffle plate 5 of a bathtub 1. In heating, water in the bathtub 1 flows through a low temperature side pipe 2 and is heated by a bath furnace 3 and then flows through a high temperature side pipe 4 and returns to the bathtube 1 while thrusting the spring 8 inwards to open the check valve. During fire extinguishment, the check valve is closed by the spring 8 and the circulation pipes 2, 4 are shut off so that a circulation passage is disconnected. Therefore, hot water convection does not occur during the fire extinguishment, accordingly, the water once heated and stored in the bathtub 1 is not heat-exchanged at the furnace 3 nor the heat of water dissipates during convection.
