Title: Alternate automatic operation control device for motor-driven
Inventor: SATO MITSUHIKO
IPC: F04D15/00
Filed: 1993-02-17
Abstract: PURPOSE:To switch operation of first and second pumps with a proper detection of water levels by parallelly connecting a circuit, in which a proper resistance and diode are serially connected, to a resistance of an input part in an automatic operation circuit. CONSTITUTION:Alternate and intermittent operation of pumps is performed by means of an integrating circuit composed of a resistance R1 of an input part of an automatic operation control circuit which processes signals from a water level sensor for regulating starting and stopping water levels of the first and second pumps, and a capacitor C. A resistance R2 having a resistance value smaller than that of the resistance R1 of the input part and a diode D1 are serially connected to form a circuit which is parallelly connected to the resistance R1 of the input part, in the automatic operation circuit which processes the water level signals from an upper limit water level sensor SH2 for starting the second pump. Erroneous operation does not occur even in the condition that remarkable wave and bubbles are generated on the water surface and the water level signals from the sensor repeat ON-OFF states in a short time.

Filed: 1982-03-31
Abstract: PURPOSE:To obtain the titled dry ice block of larger volume in the optimum state by repeating a pressing stage >=2 times while making the molding rate proper when snow produced by spraying liquefied CO2 into a molding chamber is press-molded. CONSTITUTION:Liquefied CO2 is sprayed into a molding chamber 1 from a nozzle 5 through piping 3 and a valve 4 to produce snow. By lowering the pressing plate 6, the snow is pressed against the sliding lid 7 to form block-shaped dry ice (expressed as a moldedproduct hereunder), the lid 7 is slid, and the molded product is taken out by pushing. At this time, in the 1st spraying stage, snow is produced by an amount corresponding to a proper molding rate for the volume of the chamber 1, and the 1st pressing stage is carried out to form a molded product 8. In the 2nd spraying stage, snow is produced by an amount corresponding to a proper molding rate for the volume given by subtracting the volume of the product 8 from the volum of the chamber 1, and the 2nd pressing stage is carried out to form a molded product 9. Since the products 8, 9 are easily fused into one body, a large-sized molded product is obtd.

Abstract: PURPOSE:To improve the elongation and contraction rate, tear strength, etc., of electrostatic recording paper and to improve the quality and copying speed of a copied image by impregnating a conductive agent to wood free paper having a specific basis weight and air permeability, then providing a dielectric layer thereon and adjusting the transparency to >=40%. CONSTITUTION:The wood free paper which satisfies particularly the conditions of 35-45g/m<2> basis weight, and <=300sec air permeability is adequate as the raw paper to be used. The tear strength is low and the stiffness is so weak that the paper does not lend itself to a drawing if the basis weight is <35g/m<2>. The transparency is poor if the basis weight increases >=45g/m<2>. The transpar ency is not improved even if the conductive agent is impregnated to such paper. The conductive agent is hardly impregnate and the image density is low with an electrostatic printer of a both-faces control system if the air permeability exceeds 300sec. One side or both sides may be further subjected to conductive processing after the impregnation of the conductive agent.
