Inventor: KASHIWAGI KOUZOU
IPC: B23K35/30
Filed: 1979-06-28
Abstract: PURPOSE: A silver braze alloy which is composed of respectively specified ratios of Ag, two or more kinds of Ni, Sn and In, and Cu and which is capable of decreasing the roughening of the braze surface after brazing by decreasing the surface tension of the braze material melted at the brazing.  
     CONSTITUTION: This silver braze alloy is constituted by 63W90wt% Ag, 0.05W 4.5wt% two or more kinds of Ni, Sn and In, and Cu for the remainder. Below 0.05wt% of the content of two or more kinds of Ni, Sn and In in particular, the occurrence of the roughening and concaves or convexes of the braze surface after brazing canont be suppressed. On the other hand, if said content exceeds 45wt%, the effect of decreasing the roughening of the braze surface and the effect of suppressing the formation of concaves or convexes is decreased considerably.

IPC: H02P23/04
Filed: 1990-03-28
Abstract: PURPOSE:To prevent oscillation of output torques by controlling the load current of a servomotor through the PWM voltage control of an inverter. CONSTITUTION:A digital signal processor 14 compares the current target value of a servomotor 31 with the current feedback value of load current detected by current transformer 32a, 32b to calculate current deviation and operates the instantaneous current command value at this time from the instantaneous current deviation at this time and the cumulative value and the current target value of the instantaneous current deviation. That instantaneous current command value is compared with high-frequency triangular waves to generate voltage control PWM signal which controls on-off states of each phase transistor of the inverter 25. This voltage control PWM signal is outputted to the inverter 25 to drive each phase transistor of the inverter 25. The load current of each pair of transistors is controlled to the current target value by switching of this inverter 25.

IPC: F24S50/20
Filed: 1979-06-29
Abstract: PURPOSE: To simplify a mechanism and heighten the efficiency of heat collection, by translating a solar light condensing lens in the axial direction of a heat collection tube in the revolution following of a solar heat collector.  
     CONSTITUTION: A heat collection tube 11 is oriented north and south and inclined in the latitude of ϕ. A fixation pin 18 is loosened to swing a lens moving arm 17 to translate a condensing lens 12 along the axis of the heat collection tube 11. As a result, the distance between the tube 11 and the lens 12 is changed. In that case, the arm 17 is swung by the double of the change in the elevation angle of the sun so that sunlight transmitted through the lens 12 is collected onto the tube 11. Since the angle of the arm 17 is adjusted once per several days, sunlight is efficiently collected all the year round and a revolution following mechanism is simplified and a heavy collector can be manufactured.

Title: Device for raising transmission efficiency
Inventor: MOCHIDA SHIGERU
IPC: F02B41/04
Filed: 1988-04-04
Abstract: PURPOSE:To aim at raising the efficiency of power transmission between a rotary motion and a reciprocating motion in a reciprocating type engine or a reciprocating type pump, by providing an eccentric shaft which integrally rotates with an external gear that rotates in the condition to mesh with an internal gear. CONSTITUTION:An external gear 6 which rotates around a crank pin 7 and an eccentric shaft 4 which integrally rotates with the external gear 6 are attached to the crank pin 7, and an internal gear 5 is fixed to a cylinder block. The number of the teeth of the gear 5 is twice as many as that of the gear 6. The force which is given to a piston 1 by explosion acts upon the (A) point of the gear 6 through a piston pin 2, a connecting rod 3 and the eccentric shaft 4, and the gear 6 rotates in the condition to be inscribed with the gear 5, so that a crankshaft 8 rotates. In this case, the (A) point is the center of the eccentric shaft 4, and it always shifts on a line by which the center of the crankshaft 8 and the piston pin 2 are joined, so that the lateral pressure which is given to a cylinder by the piston 1 can be eliminated. Therefore transmission of power between a reciprocating motion and a rotary motion can be achieved efficiently.

Title: Recycle apparatus for separated component of analysis sample
Inventor: ARICHIKA KENJI
IPC: G01N30/44
Filed: 1990-03-29
Abstract: PURPOSE:To prevent the contamination of separated component to be detected with another separated component whose recycle processing is performed beforehand by using a four-port switching valve, and connecting the valve to a waste/ recovery position after the end of the recycle. CONSTITUTION:When a separated state is not sufficient for obtaining an analyzed numerical value with a detector 40, a first port 81a, a third port 83a and a fourth port 84a of a change valve 80 are communicated, and a second port 82a is closed. Therefore, the separated component outputted from a sample- component separating device 20 enters into the separating device 20 again through the valve 80. When the separated component becomes the state sufficient to obtain the analyzed numerical value with the detector 40 as a result of the recycle, the ports 81a and 82a are communicated, and 83a and 84a are communicated. Therefore, the separated component remaining in the valve 80 which forms the recycle line at the time of the recycle flows out through a waste/ recovery flow path A from the port 82b. Thus, the dead volume part wherein the recycled separated component remains is not present in the recycle apparatus.

Title: Disk driving device
Inventor: SUZUKI YASUAKI
IPC: G11B21/08
Filed: 1989-03-31
Abstract: PURPOSE:To obtain a disk driving device capable of determining addresses by the small quantity of calculation by dividing all tracks into plural blocks and recording addresses to be changed in the blocks like sectors. CONSTITUTION:Servo areas 20a to 20h radially extended at an equal angular interval are formed in a magnetic disk 1. Address signals are previously recorded in the sector-like servo areas 20a to 20h together with servo signals. The address signals are repeated in each block consisting of plural tracks and a distance allowing a head to move during one-sector rotation of the disk 1 is set up to <=1/2 the number of data tracks in each block. Since the maximum range allowing the head to move during the one-sector rotation of the disk 1 is restricted, values in two blocks or more are not changed in the address continued in time. Since the condition is formed, the updating of blocks can be decided by the small quantity of calculation and absolute addresses can be rapidly formed.

Abstract: PURPOSE:To enable quantitative analysis with good selectivity and high accuracy by absorptiometric method without adding a color forming reagent to a soln. contg. metal ions by diluting the soln. with hydrochloric acid to form a chloride complex having an absorption region to UV rays. CONSTITUTION:The sample soln. contg. tin ions is fractionally collected from a sample dissolving vessel 10. This soln. is diluted with the hydrochloric acid to form the chloride complex having the absorption in the UV region in a diluting device 4. The dilute liquid is subjected to sepn. by an anion sepn. column 20 contg. about 0.01-3.0N hydrochloric acid is used as a mobile phase. The absorbance of the chloride complex is then measured by using the light of the wavelength of the UV region to which the chloride complex has the absorption by using an absorptiometer 22. While the absorption characteristics of the chloride complex of tin have strong absorption in a short wavelength region, the background is high and fluctuations increase at <=205nm wavelength. Since the analysis accuracy is degraded at such wavelength, the light of about 210nm wavelength is used. The absorbance is then measured by valency by using a data processor 24 and the concn. of respective tin ions are determined from a previously prepd. calibration curve.
