Title: Galvanized steel sheet having excellent formability
Inventor: YAMADA MASATO
IPC: C23C22/00
Filed: 1986-02-10
Abstract: PURPOSE:To improve the formability and corrosion resistance of a galvanized steel sheet by forming two layers of different chromate films on the surface of said steel sheet. CONSTITUTION:The electrolytic chromate film is first formed on the surface of the above-mentioned steel sheet with a known chromate liquid and electrolyzing conditions to coat the above-mentioned plating surface with the dense film which consists essentially of Cr<3+> and in which metallic Cr exists partly to improve the galling resistance in the stage of press forming. The coating type chromate film which consists essentially of Cr<6+> and has a self-restoration effect is formed by spraying of or immersion in a known chromate liquid on the upper layer of the electrolytic chromate film to improve the corrosion resistance. The lubricity is improved by the presence of the electrolytic chromate film and the exfoliation by the galling of the coating type chromate film itself in the pressing process is decreased if the steel sheet is constituted in the above- mentioned manner. The formability is thus improved.

Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To assure not to have degradation of developability due to fluctuation of SD intervals by inserting a parallel connected capacitor and resistor into the output side of a bias power source. SOLUTION: A developers are fixed to an image forming device body and the layer thickness of the developer layer on a developer carrying member is smaller than the spacing between the developer carrying member and image carrying member in a developing section. A bias power source 7 is constituted by inserting the parallel connected capacitor C1 and resistor R into the output side of a series connected AC voltage source EAC and DC voltage source EDC. According to such bias power source 7, the VP impressed on a developing sleeve is VPP=VPP0 ×C1 /(C1 +C2 ) if the electrostatic capacity of the capacitor C1 is C1 as it is when VPP on the bias power source 7 side is defined as VPP0 .  According thereto, the term of the electrostatic capacity increases if the SD intervals increase and the electrostatic capacity C2 between the SD decreases and, therefore, the VPP increases and the developability by developing biases is enhanced.

Title: Method and apparatus for detecting extraneous matter in liquid
Inventor: TAKAHASHI TOSHIO
IPC: C02F1/72
Filed: 1979-03-08
Abstract: PURPOSE: To efficiently detect extraneous matter in a liquid in an ampule irrespective of the viscosity of the liquid, size and shape of the ampule and quantity of the liquid in the ampule, by inhibiting an output from a small light receiving element opposed to an ampule containing extraneous matter.  
     CONSTITUTION: An ampule 1 filled with a liquid is rotated at a high speed to be then stopped suddenly. Extraneous matter which is still rotated in a floating state with the liquid in the ampule is irradiated with light. The beam permeated through the liquid is received by a light receiving portion of an optical detector 7 provided in opposition to the ampule 1. The detection of extraneous matter mixed in the liquid is conducted with reference to variations in the amount of beam received by the light receiving portion of the detector 7. The light receiving portion consists of an aggregate of small light receiving elements 7 1 W7 n . An output from a small light receiving element 7m in opposition to a spiral liquid surface 8, which is formed by the rotation of the liquid, causes an extraneous matter detection circuit 11 to be turned on to inhibit an output from an AND-circuit 13m. A solenoid connected to an output terminal 19 is then actuated to remove the faulty ampule.

Abstract: PROBLEM TO BE SOLVED: To provide an sensing type automatic faucet and its sensing method installed on the tip of an existing faucet easily without using an electricity at all. SOLUTION: An automatic faucet 1 is composed of a main valve consisting of a diaphragm 111 and a pilot valve 211 for opening/closing the main valve by the control of a water pressure mainly. The operation of the pilot valve 211 is controlled by a magnet on the outside of the automatic faucet through a float 213 mounting the magnet on the upper/lower parts in its separated chamber. In the automatic faucet 1 installed to the existing faucet at a connection part 18, the pilot valve 211 is closed by the pressure of a water streaming from the faucet and the diaphragm 111 is also closed by the rising water pressure and the automatic faucet 1 becomes a water stop state. By bringing the magnet close from the outside, the pilot valve 211 is opened/closed by the float 213 being elevated.  Consequently, the diaphragm 111 is also opened/closed and the automatic faucet 1 repeats water discharge and water stop.
