Title: Production of xanthene dye by electrolysis
Inventor: AIZAWA TAKAO
IPC: C25B3/23
Filed: 1989-09-20
Abstract: PURPOSE:To efficiently synthesize a xanthene dye by electrolytically oxidizing the leuco compound of the xanthene dye. CONSTITUTION:A compd. represented by formula I is electrolytically oxidized in an electrolytic cell to produce a xanthene dye represented by formula II. In the formulae I, II, each of R1 and R2 is lower alkyl, Y is H or a sulfonic acid group and X is a cation. The pH of a reactive soln. is usually adjusted to 5-10 and the electrolytic reaction is carried out at about 1-200mA/cm<2> current density. After the reaction, the product is usually in a dissolved state and can be separated from the soln. as usual. For example, the product is crystallized by salting out in an acidic state and filtration is carried out to obtain a high purity dye.

Abstract: PURPOSE:To convert the angle of rotation of a resolver into a digital signal by operating the difference between the outputs of 1st and 2nd multiplication type D/A converters and outputting it as the control input of a voltage- controlled oscillation means. CONSTITUTION:The rotor winding 10c of the two-phase excited and one-phase output resolver 10 is connected to the analog reference input of a multiplication type D/A converter 2a constituting a multiplying means 2 and its output is connected to the uninvested input (+) of a subtracting means 4 consisting of resistances 4a - 4d and an operational amplifier 4e. The output of a sin2theta/2- function generating means 11 consisting of a ROM 11a, a multiplication type D/A converter 11b, and a variable resistance 11c, on the other hand, is connected to the inverted input (-) of the subtracting means 4. The voltage-controlled oscillation means 5 oscillates by receiving an error output which is the output of the subtracting means 4 to output a pulse train to a counting means 6, which outputs a digital signal; and a costheta-function generating means 7 and the sin2theta/2- function generating means 11 send their outputs to the multiplying means 2 and subtracting means 4 respectively. Consequently, the angle thetam of rotation of the resolver 10 is accurately converted into the digital signal.

The material M is then subjected to draining with a draining device 11. The surface temp. of the material M is measured by a temp. detector 15 right after the draining. While the material is successively conveyed in the atm. up to a coiler 21, the surface layer part is recuperated by the heat transfer from the high-temp. central part. The recuperation temp. is measured by a temp. detector 17 at the point where the temp. difference between the surface and center of the material M in the midway of conveyance attains about <=10 deg.C. The amt. of the cooling water to be supplied to the box 7 is set in accordance with the results of the measurement by the detectors 15, 17. The material M is thus cooled at the required cooling rate.

Title: Method of repairing short-circuit section of substrate
Inventor: KASUGAI HIROAKI
IPC: B41J2/345
Filed: 1988-09-28
Abstract: PURPOSE:To repair a particularly fined pattern short circuit section by applying high- voltage short pulses to a wiring-pattern short circuit section when a short circuit section in which the line width of the repair of the wiring-pattern short circuit section being composed of a gold conductor for a thermal printer head and having specific film thickness is made smaller than that of a conductor section is repaired. CONSTITUTION:The pattern of gold conductors 1 is formed through etching, but a short circuit 3 between the conductors is generated. The line width of the short circuit section 3 is hardly made smaller than the line width of the conductor, thus making electric resistance larger than the conductor pattern section. Currents are not made to flow because a circuit is brought to an open state when voltage is applied between terminals 5, 6, but currents are made to flow through a short circuit section 4 when voltage is applied between the terminals 6, 7 including the short circuit section. The short circuit section 3 having line width smaller than the conductor section 1 is heat- generated and fused because the section 3 has a large resistance value. Pulses are used as applied voltage. When pulse voltage is applied, possibility in which sections except the short circuit section are fused is reduced extremely even when voltage higher than voltage required for fusing the short circuit section is applied.

IPC: H03K19/00
Filed: 1990-09-13
Abstract: PURPOSE:To reduce power consumption by providing plural semiconductor constant current circuits separately to this circuit and inputting plural control signals externally to relevant CMOS gate circuits so as to apply on/off control to the supply of a constant current. CONSTITUTION:When a logic signal is given to only, e.g. an i-th input terminal INi in the semiconductor integrated circuit and the other circuit portion is turned off, an L level signal is given to a control signal terminal ISi and an H level signal is inputted to other control signal input terminals ISj (jnot equal to i. In this case, since an L level is given to the input of a current control circuit SWi, a transfer gate T is opened and a voltage source VCS is supplied to the control circuit, its constant current source is active, but the supply from the voltage source VCS to the constant current sources for the other circuits IBj, INTj and OUTj is interrupted. Thus, useless power consumption is avoided.

Filed: 1988-09-28
Abstract: PURPOSE:To improve the color change and degradation in contrast according to visual angles by disposing a double refractive medium in such a manner that the direction of the max. refractive within the plane thereof coincides approximately with the transmission axis or absorption axis of the polarization of a polarizing means. CONSTITUTION:The double refractive medium 8 has optical uniaxial or biaxial anisotropy and has light transmittability. The medium has the anisotropy in the refractive index within the plane parallel with a substrate and is so disposed that the direction C1 of the max. refractive index within the plane and the transmission axis or absorption axis of the polarization of an adjacent 1st polarizing means 2 are approximately paralleled. The approximate parallel in this case refers to an angle within 10 deg., more preferably within 5 deg.. The dependency on the visual angle is decreased without impairing the contrast by adopting such disposition.

Title: Magnetostrictive torque sensor
Inventor: SUNAHATA MUTSUMI
IPC: G01L3/10
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To reduce an air gap in a diameter direction between an outer periphery of a magnetically anisotropic part and an inner periphery of a bobbin for winding a coil in a magnetostrictive torque sensor with the coil placed around the magnetically anisotropic part formed on a surface of a torque transmission shaft. SOLUTION: An inner periphery of a bobbin 32 for winding coils 36, 36 is supported by an outer peripheral face of a torque transmission shaft 51. Then concentricity between the torque transmission shaft 51 and the bobbin 32 is determined only by machining accuracy of two members of the torque transmission shaft 51 and the bobbin 32. Therefore, size tolerance in a diameter direction is not accumulated, so that an air gap can be reduced.

Title: Ink jet recording head and ink jet recording device
Inventor: SAIKAWA HIDEO
IPC: B41J2/205
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a high image quality and high gradation ink jet recording head which is capable of printing data a more rapid velocity by shortening a large liquid droplet refilling time as a recording head having two electricity/ heat conversion elements in a single nozzle and a recording device using the recording head. SOLUTION: In the ink jet recording head with two electricity/heat conversion elements 53, 54 incorporated in a single nozzle, the length of the far-side electricity/heat conversion element 54 in the liquid droplet discharge direction from an orifice 40 is smaller than that of the near-side electricity/heat conversion element 53. Consequently, a bubbling center is moved farther backward (an opposite side to the orifice 40), so that a flow resistance backward from the bubbling center becomes less, resulting in the easier refilling of an ink the rear end. Thus it is possible to realize the shorter refilling time.
