Title: Ink supply mechanism of on-demand type ink jet printer
Inventor: YASUHARA MASATOSHI
IPC: B41J2/175
Filed: 1986-03-17
Abstract: PURPOSE:To provide an ink supply mechanism of an on-demand type ink jet printer capable of always printing under satisfactory condition by keeping the internal pressure of a sub-ink tank in a carrier at a constant level. CONSTITUTION:A sub-ink tank 6 which temporarily stores ink is installed on a carrier 11 and air 7 is sealed there with the ink. In addition, a pressure sensor 8 is provided and the ink of the sub-ink tank 6 is increased by an ink supply pump 4. At the same time, the pressure of the sealed-in air increases. If the pressure sensor 8 detected that an increase in the pressure has reached a set pressure level, the drive of the supply pump 4 is stopped to terminate the ink supply. In addition, the flowback of ink in a supply tube 3 due to the existence of an internal pressure in the sub-ink tank 6, is prevented by a check valve 5. During printing, this process is sequentially performed, making it possible to carry out satisfactory printing all the time.

Filed: 1987-03-14
Abstract: PURPOSE:To enable a high resolution to be obtained by providing a plurality of the groups of magnetoresistance effect elements (MR) wherein an output fundamental and one of the higher harmonic components for the output fundamental harmonic have reverse phases to each other and one canceled each other. CONSTITUTION:A magnetic medium 3 having magnetic poles 31 with pitches lambdais arranged on a rotary drum 2. A magnetic sensor 4 wherein the groups of MRs are arranged at prescribed spacings opposite to the magnetic medium 3 is fixed with a spacing lg from the medium 3. The group of the MRs is constituted by MR elements R11-R14 and R21-R24 located on a sensor substrate 41 and those elements are arranged as shown. Thus, one higher harmonic component for an output fundamental is canceled by the MR groups having reverse phases canceled by each other. By conducting canceling action on the whole higher harmonic components, only fundamental components with sinusoidal waveforms can be taken out. Therefore, even when the spacing lg changes due to the eccentricity of the medium 3 or the like, a high resolution can be obtained.

Title: Analogue speed detector
Inventor: ITOU JIROU
IPC: H02P29/00
Filed: 1979-05-18
Abstract: PURPOSE: To keep detection accuracy and trasient response good through a simple construction, by compensating the analogue voltage signal of a pilot electricity generator by the pulse signal of a pulse oscillator.  
     CONSTITUTION: An adder subtracter 4, a signal converter 3 and an integrator 6 are provided. The adder subtracter 4 compensates the analogue voltage signal of a pilot electricity generator 1 by an analogue error signal to supply a speed detection signal as an output. The signal converter 3 changes the pulse signal of a pulse oscilltor 2 into an analogue voltage signal proportional to the frequency of the pulse signal. The integrator 6 integrates the difference between the output signals of the signal converter and the adder subtracter to supply an analogue error signal as an output. When the analogue voltage signal of the pilot electricity generator 1 has an error, an integrated error value appears on the output of the integrator 6 and a polarity converter 5 performs polarity conversion to supply an analogue error signal to the adder subtracter 4 to correct the error of the analogue voltage signal. Detection accuracy and transient response can thus be kept good by simple constitution.
