Title: Oil densitometer
Inventor: NISHINO TAKEKAZU
IPC: G01N21/35
Filed: 1978-07-22
Abstract: PURPOSE:To facilitate operation, by eliminating the need for adjusting a location of a reflection optical system by changing the wavelength of infrared rays by exchanging light sources and an interference filter while light passing through the interference filter is condensed by means of the reflection optical system and sent to a detector. CONSTITUTION:The light R of light sources 11 or 12 exchange selected in respone  to the kinds of oil or oily matter is reflected by means of a concave mirror 21, and guided to a simple liquid tank 50 through a standard plate 40 for correction and a chopper 31. Light from the sample liquid tank 50 permeates an interference filter 60 exchange selected in response to the kinds of oil or oily matter, and monochromatic light with specified wavelength is introduced to a detector 70. Thus, the adjustment of a location of a reflector optical system is unnecessary and the concentration of oil over wide ranges can accurately be measured in conditions that operation is easy, structure is simple and the cost of production is inexpensive even if the light sources 11, 12 and the interference filter 60 are exchanged in response to oil or oily matter and the wavelength of infrared rays is altered.

Title: Manufacture of phosphor bronze strip
Inventor: HASHIZUME KIMIO
IPC: B22D11/00
Filed: 1989-04-10
Abstract: PURPOSE:To prevent the development of crack and breakage and to enable stable manufacture by executing casting under condition of inclining a line connecting axes of one pair of cooling rolls at the specific angle to the vertical direction and taking out a cast strip along a guide having inclining angle to the horizontal direction corresponding to almost the above angle. CONSTITUTION:The molten metal 1 in a tundish 2 is supplied into molten metal basin 6 between one pair of the cooling rolls 5 through a nozzle 3 and a trough 4. The molten metal 1 starts to solidify by being subjected to the cooling action of each cooling roll 5 to form solidified shell 5a. The line R connecting the axes O for the above one pair of cooling rolls 5 is inclined at 15-65 deg. angle to the vertical line V. The solidified shell 5a is pushed out as following with rotation of the cooling rolls 5 to form the cast strip 7 inner part of which is the state of solid-liquid coexistence. This cast strip 7 is drawn out along the guide 8 having the inclining angle theta2 to the horizontal direction almost corresponding to the inclining angle theta1 of the line R connecting the axes O for the above rolls 5 to obtain the phosphor bronze strip 7 having long scale.

Title: Temperature compensating circuit of carrier detection for photodetector
Inventor: SEGAMI KOUICHI
IPC: H04B10/572
Filed: 1981-06-08
Abstract: PURPOSE:To perform the temperature compensation for the detection of carrier to the variation of the conditions in a simple way, by securing the independent decision for the setting of the voltage value and the ratio of the temperature change with the offset adjustment of a differential amplifier. CONSTITUTION:The resistance 2 and 3 are connected in series to each other, and the reference voltage value for the carrier detection is set along with the changing degree of voltage due to the temperature. A thermistor 1 is connected in parallel to the resistance 2. A differential amplifier 8 has a pair of input terminals. One of these input terminals is connected to a joint between the resistances 2 and 3, and the other side is connected to a voltage terminal 7 for setting the reference voltage value of the carrier detection. Then the output terminal 6 of the amplifier 8 is used for the extraction of the reference voltage of the carrier detection. Thus the setting of the voltage value and the ratio of the temperature change can be decided independently of each other with the adjustment of an offset adjusting part of the amplifier 8.

Title: Superconducting rotor
Inventor: INOUE KOICHI
IPC: H02K3/04
Filed: 1990-04-06
Abstract: PURPOSE:To enable the increase of field currents so as to get a strong magnetic field by setting the number of parallel circuits at least at the part to become high magnetic flux density of a superconducting field winding to two or more so as to decrease current density. CONSTITUTION:The field winding 1 of the superconducting rotor of four poles is fixed firmly to the field winding attaching axis 2 consisting of a highly strong nonmagnetic steel. The coil #1 of the field winding 1 is made by the constitution of 4 rowsX10 stages of superconductors 1a. A parallel circuit is made in the inside diameter part (hatching part) of the coil #1 to become high magnetic flux density. For example, if the number of parallel circuits in the hatching part is set to two, the number of windings in this part becomes seven turns, and the number or windings in the left one parallel circuit becomes twenty six turns. This way, the number of parallel circuits in the part to become high magnetic flux density becomes two, so the current density in this part is reduced by half. The efficiency in use as the whole of field winding improves.

Abstract: PURPOSE:To eliminate difference in the printing density in reciprocating stroke by reciprocating a running unit in which a plate roll, an application roller, an oscillating mechanisms therefor and an ink roller group are mounted on a frame base to perform a printing on a strip body. CONSTITUTION:Simultaneously with the running of a running unit 11 to the left, a plate roll 1 rotates, oscillates to the final roller 8 of an ink roller group 4 with a cam plate 34 in the latter half of the outgoing stroke and an application roller 3 fed with an ink oscillates to apply the ink on the surface of a plate 2. After the application of the ink, the roller 3 oscillates to the roller 8 to be fed with the ink. Then, with the further running of the running unit 1, the ink fed at the right angle to perform a printing on the surface of the strip body 48 halted momentarily. Then, with a shift to the incoming stroke, the application roller 3 oscillates to the plate roller 1 with the cam plate 34 to apply the ink. The same operation is repeated to complete a printing. Thus, the application of ink can be done with one application roller thereby eliminating difference in the printing density in the reciprocating stroke.
