Title: Color image recorder
Inventor: FUKUYAMA MAKOTO
IPC: B41J2/525
Filed: 1990-08-09
Abstract: PURPOSE:To prevent color slurring caused by the expansion and contraction of a recording medium by correcting each color latent image forming position based on the expansion and contraction of the recording medium in its carrying direction according to the detected result of resist marks formed on the recording medium. CONSTITUTION:The color image recorder has a resist mark detecting means 5 upstream of a recording medium carrying direction and at least a distance obtained by adding a resist mark interval to the maxim expansion of the recording medium corresponding to the resist mark interval apart from a latent image forming means 6. When a record control means 9' forms a latent image, record position aligning in a recording medium carrying direction is carried out based on the intervals of the resist marks detected by the resist mark detecting means 5. Thus, color images are accurately superimposed and the color slurring of a recorded image caused by the expansion and contraction of a recording medium is prevented.

Filed: 1982-11-30
Abstract: PURPOSE:To suppress the error operation of the titled circuit to noise light having ciclicity, by generating the output of AND circuit only when light input is absent in the front edge of the pulse signal of an socillator circuit and present in the rear edge of said pulse signal. CONSTITUTION:The rising and falling timing of the output signal from a level discrimination circuit 5 inputted to the data inputs D1, D2 of FF11, 12 is slightly delayed from the rising and falling timing of the output signal from an oscillator circuit 1 by the delays of a light receiving element 3 and an amplifier circuit 4.

When noise light is incident, the output of an AND circuit 14 does not statically come to the ''H'' level while the output of an integrator circuit 7 does not reach the reference level of a wave form shaping circuit 8 and output is always the ''L'' level.

Title: Lead storage battery
Inventor: HASEGAWA TOSHIAKI
IPC: H01M50/60
Filed: 1983-11-08
Abstract: PURPOSE:To obtain a liquid-injection exhaustion equipment of high manufacturing efficiency which has an excellent liquid overflow resistance by installing a funnel under the center of a lid for a cell, which has small hole in its slanting section and has a cylinder reaching electrolyte, and installing a cover having a small hole over the upper opening of the funnel. CONSTITUTION:A cover 5 is continuous with a lid for a cell through a hinge 8. After the cover 5 is folded on the joint section while maintaining its sufficient strength, the cover 5 is fixed convering the top opening of a funnel 4. The lower portion of the cylinder 11 of the funnel 4 reaches electrolyte. Since the inner diameter of the cylinder 11 is 15mm. or less, even under the condition of vibration, the behavior of the electrolyte is small and its splash is suppressed to the utmost. The cover 5 repels splashes jumping up through a small exhaust hole 12 provided in the slanting section of the funnel 4. The splashes scarcely reach the small hole 13 of the cover 5 becuase the small holes 12 and 13 are not located on the same vertical line. Moreover, owing to a partition wall 7 fixed to the slanting section, the splashes do not reach the small hole 13 almost entirely. Consequently the liquid overflow resistance of the liquid-injection exhaustion equipment is remarkably increased.
