Patent JP-S58129615-A (JP)
Title: Constant current device
Inventor: SAGANE TOMIYASU
IPC: G05F1/32
Filed: 1982-01-29
Abstract: PURPOSE:To simplify a circuit configuration and to remove a current detector by winding the 3rd winding around a boosting transformer and applying control voltage corresponding to load current extracted from the winding to an error amplifier. CONSTITUTION:The 3rd winding N is wound around the boosting transformer T' and voltage generated from the winding N is applied with reverse polarity against reference voltage ES to an amplifier IC in the error amplifier ER' through a rectifier D2, a resistor and a smoothing circuit in a capacitor. The carried current of an output wave at the regularly applied voltage can be adjusted by resistance ratio R4/R5. Thus a constant wave characteristic is obtained by compensating it through the selection of the resistance ratio and the resistance ratio can be sufficiently reduced, enabling a phase compensating circuit to be removed.

Title: Self-diagnostic mechanism of 'karaoke' terminal sound source
Inventor: TSUMURA MIOTSUGU
IPC: G10H1/00
Filed: 1990-01-22
Abstract: PURPOSE:To confirm the operation of a 'KARAOKE' (orchestration without lyrics) terminal sound source with a simple mechanism by outputting all sampled waveforms, stage by stage, individually and turning on an error pilot lamp unless an output value reaches a specific level. CONSTITUTION:As for a stage having a 1st number among numbers given to the respective stages, a 1st waveform number among waveform numbers given to the respective sampled waveforms is selected and an analog waveform is outputted with constant sounding strength. This output is inputted to an A/D converter 3 and when the input is 0, a low output is sent to a main substrate 1 not as an analog output of a sampled waveform; and an LED is turned on and a test is finished. Thus, a next stage is checked repeatedly, this loop is repeated up to a final stage, and when the LED does not illuminate, it is decided that the sound source and an address are normal. Consequently, it can surely be judged by the simple mechanism whether at least the sound source is normal or not.

Title: Ignition for hydraulic spray type burner
Inventor: MISHIMA TOSHINORI
IPC: F23Q3/00
Filed: 1980-02-05
Abstract: PURPOSE: To prevent soiling of an ignition bar and generation of a noise, by a method wherein an oil pump is energized in a slight delay later than an electromagnetic valve for fuel is energized.  
     CONSTITUTION: In a hydraulic spray type burner in which an electromagnetic valve 4 for combustion is placed on an oil pipe line 3 running from an oil pump 1 to a nozzle 2, the oil pump 1 (P) is energized in a slight delay later than the electromagnetic valve 4 (OV) for combustion is energized. In the case of firing, the electromagnetic valve 4 is set into OFF by energizing the electromagnetic valve 4 (OV) for combustion, an ignition transformer IG, and a timer T, and sparks are emitted from a forward end of an ignition guide 5. After a set time for a timr T has elapsed, the oil pump 1 (P) is energized and oil is sprayed through a nozzle 2 slowly as an oil pressure is raised through starting of the oil pump 1 (P). This permits starting of the burner in a condition to be reduced in an oil amount when firing, and thereby a combustion starts smoothly and spoiling of a firing bar and generation of a noise, which are due to a shock and a blow-back at a firing time, can be prevented.

Abstract: PURPOSE:To produce the title compound hardly containing any impurities, by successive ly carrying out six steps including steps of removing various metallic ions from a solution of a Tacontaining raw material in HF-HCl with a cation exchange resin and adsorbing the Ta component on an anion exchange resin. CONSTITUTION:A solution of a Ta-containing raw material in HF and HCl is passed through a cation exchange resin to remove various impurities, such as Fe, Mn and Ni (first step). The resultant solution is then passed through an anion exchange resin to adsorb the Ta component thereon (second step). The impurities adsorbed together with the Ta component are subsequently washed in several steps (third step). The anion exchange resin adsorbing the Ta component is then eluted with a mixed solution of NH4NO3 and NH4F to separate the top.fraction thereof (fourth step). NH3 is subse quently passed through the residual Ta eluate to regulate pH to 6.8 and precipitate tantalum oxyfluoride (fifth step). The resultant precipitates are then filtered, washed and dissolved with HF to provide a solution. NH3 is subsequently passed therethrough to coprecipitate part of the Ta. The obtained precipitates are then filtered and the resultant filtrate is reacted with acidic KNO3 to afford crystals of K2TaF7, which are filtered, washed and dried to afford the final product (sixth step).

Abstract: PURPOSE:To enhance sealability and stress resistance and to improve reliability of a chip-on-flexible printed board (COF) by integrating sealing resin with a reinforcing plate in a state for holding a flexible printed board (FPC). CONSTITUTION:Heated fluidized sealing resin is so dropped in a state that a protrusion 6 is passed through a hole 7 as to cover a semiconductor 3. When the resin reaches the protrusion 6 protruding on an FPC 1, the protrusion disturbs the flow of the resin to stop the flow of the resin, and the resin is cured at the point to form a sealed part 8. A reinforcing plate 5 is integrated with the part 8 by selecting the materials of the plate 5 and the resin with excellent sealability, the FPC 1 is formed in a state in which both are held, and the part for connecting the semiconductor 3 to a wiring pattern 2 is so reinforced as not to bend the plate 5. Accordingly, even if a bending stress is operated at the part 8, the resin is not peeled from the FPC to eliminate the stress at the connection part of the semiconductor 3 to the pattern 2.

Trivalent iron and color former are separately added to prepare the first or second reagent. The reagent containing the trivalent iron is reacted with blood serum and the reagent containing the color former is added and reacted therewith. As a result, unsaturated transferrin in the blood serum is bound to the added iron to provide saturated transferrin and unbound iron is reduced from the trivalent iron into bivalent iron and bound to the color former to assume a color. The amount of the unbound residual iron is subtracted from the known excess amount of the iron to calculate the unsaturated iron binding ability.
