Title: Liquid volume detecting method, recorder and information processing system applied the same method
Inventor: TORIGOE MAKOTO
IPC: B41J2/175
Filed: 1994-06-03
Abstract: PURPOSE:To detect the ink residual amount of an ink tank of different color by a single light source by disposing the source at a predetermined angle to the first surface of a vessel, and providing a photodetector on an optical path of the light to be irradiated from the second surface of the vessel when the liquid volume is zero. CONSTITUTION:Liquid volume detecting means having a photodetector 4 for detecting the wavelength of a light to be irradiated from a light source 3 is provided in an ink tank 1 having an atmosphere communication port 8 at its upper part to supply ink 2 to a recording head 5 via a supply port 7 of an ink jet recorder. In this case, if the incident point of the light to the surface of the tank 1 is higher than the liquid level of the ink 2, the source 3 is so obliquely disposed that an incident angle theta becomes theta>arcsine (1/n) (n: the refractive index of the ink) so as to allow the light to be incident to the first surface and then arrive at the second surface of the tank 1. If the liquid volume is zero, a photodetector 4 such as a CCD, etc., is disposed on the optical path of the light to be irradiated from the second surface of the tank 1.

Title: Fixing method of color electrocopying
Inventor: INOUE SATORU
IPC: G03G13/01
Filed: 1978-10-09
Abstract: PURPOSE: To eliminate cold offsetting, etc. letting the lowermost layer on transfer paper be a layer other than of yellow toner or magenta color toner layer and making the softening point of the lowermost layer toner thereof lower than the softening point of other two colors.  
     CONSTITUTION: First, magenta images are transferred by the magenta toner M on transfer paper 1, thence cyan images are overlapped and tranferred thereon by the cyan toner C and finally yellow images by the yellow toner Y are overlapped and tranferred thereon to form color copy images 2. This results in that the yellow toner Y is on the magenta single color part. Hence, when the softening point of the magenta toner M is made lower than the softening points of the other two colors, the lower limit temperature of the magenta toner M itself at which hot offsetting occurs becomes lower than that of the other two colors but the yellow toner Y is on the magenta single color part and therefore the magenta toner M of the lowermost layer of the 3 color overlapped parts perfectly melts, thereby obviating the occurrence of cold offsetting. In addition, the occurrence of hot offsetting in the magenta toner M single color part is obviated as well.

Title: Quenching process by laser
Inventor: INAGAKI MASATOSHI
IPC: C21D9/32
Filed: 1979-09-28
Abstract: PURPOSE:To provide an excellent quenching effect over the entire surface area by a method wherein two laser beams having a specified cross angle are projected onto the surface of the teeth base of a gear or rack so that the laser beams cross over them. CONSTITUTION:Two laser beams having a cross angle more than twice the pressure angle of teeth of a rack, etc. are used. In the case of a rack 10, for example, the rack 10 is being moved in the direction of the arrow 16, and two laser beams 12, 14 having the cross angle twice the pressure angle A are projected so that they cross each other on the base surface 18 of the teeth. In the state of (a), the teeth base surface 18 is quenched. In the state of (b), the left side is quenched. Moving to the teeth surface 22, the right side is started to be quenched at the state of (c). Sequential quenching thus continues. To provide laser beams with a specified angle, a laser beam 26 from an oscillator 24 is changed by an expander 28 in its diameter and formed into a parallel beam 32, which is handled by a division-mirror 34, a cylindrical concave mirrors 36, 38 so that laser beams 12, 14 cross over at the specified location. The process thus provides a quench operation over the entire surface area.

Filed: 1982-07-16
Abstract: PURPOSE:To enable to compose a load of low power type by connecting in series a plurality of FETs which are comonly connected at gates between a power source and a drive transistor. CONSTITUTION:Load FETs 2 connects commonly at the gates are inserted in series between a power source 2 and a drive FET3, and a load FET is further associated in parallel.

When the two fundamental loads FETs of different characteristics are used four load FETs can be selected, and when three are used, seventeen load FETs can be selected. Further, when depletion type FETs connected commonly at the gates are connected in advance in series with each other, and altered at the connecting position to the power source, the capacity of the load FETs can be varied, thereby facilitating the acceleration of the speed and the conversion to low power.

Title: Cleaning leader tape

IPC: G11B5/41
Filed: 1982-07-16
Abstract: PURPOSE:To eliminate the sticking of dust, a spark noise, etc., by applying a paint, where a white pigment having a specific particle size is mixed, to the surface of a nonmagnetic base subjected to an antistatic treatment. CONSTITUTION:A paint 2 where 5-100pts.wt. white pigment having a particle size of 0.002- 3.0mu to 100pts.wt. binder is mixed is coated onto the surface of a nonmagnetic base 1 which is subjected to an antistatic treatment and consists of materials superior in transparency, and after drying, the surface roughness of a tape 6 is set to 0.1-1.5mu. The method where a layer consisting of an antistatic agent is provided on the surface of the nonmagnetic base film by application or immersion, the method where the antistatic agent and a conductive resin are added to materials of the nonmagnetic base to form the film or the like is adopted to perform the antistatic treatment. If the particle size of the white pigment exceeds about 3.0mu, the surface is rougher to increase the wear of a head; and if the particle size is smaller than 0.002mu, the cleaning effect is lost. If the proportion of mixture of the white pigment to the binder exceeds 100pts.wt., the adhesive strength and the light transmissivity are degraded and the obtained film is undesirable; and if this proportion is lower than 5pts.wt., the practical cleaning effect is not attained. The electric resistance of a leader tape using the base subjected to the antistatic treatment is lowered considerably in comparison with contrast examples, and this tape is improved in respect to the spark noise.
