Title: Automatic cock unit
Inventor: OTAKE TAKASHI
IPC: E03D5/10
Filed: 1994-10-07
Abstract: PURPOSE: To set and control a water quantity accurately in time of water supply by installing a stop cock in a supply channel and also a generator detecting a supply flow rate respectively, and simultaneously installing a pilot lamp displaying it at each specified stage conformed to the detected flow rate, or displaying it continuously in proportion to the detected flow rate otherwise. CONSTITUTION: A stop cock 42 is set to a proper opening in a state that a diaphragm type valve element 43 in automatic cock unit 2 is opened, thereby making water flow into a supply channel 4. If so, with this water passing, a disc wheel in this supply channel 4 is rotated, and a generator 44 connected is integrally rotated together and thus power generation is started. So, with the extent of output in this generator 44, the rotational frequency per unit time is found out, and it is converted into the supply flow rate. Accordingly a display pattern is selected by way of whether this supply flow rate exceeds each judged flow rate or not.  With this constitution, opening of the stop cock 42 is adjusted as checking a lighting pattern of a pilot lamp and then those of overs and shorts in flushing water quantities at each toilet bowl are prevented from occurring and, and the variations are solvable.

Title: Bias magnetic field generator
Inventor: MIZUNO OSAMU
IPC: G11B5/02
Filed: 1986-11-13
Abstract: PURPOSE:To improve the efficiency of the titled device and to shorten the rising time of a magnetic field by minimizing field gap width constituted between an outside york and a center york through a magneto-optical recording medium at a face opposed to the medium and expanding it in accordance with its separation from the recording face of the medium in the normal direction. CONSTITUTION:A chamber part 60 is formed on the back of one face of the outside york opposed to the medium 1 and the magnetic gap width formed between the center york 5 and the outside york 6 is set up so that the magnetic gap width S' formed on the opposite side to the face opposed to the medium 1 is larger than the magnetic gap width S formed on the face opposed to the medium 1. Since magnetic flux passing the opposite side to the face opposed to the medium 1 is reduced and magnetic flux passing near a recording point on the medium 1 is increased in accordance with the decrease, the efficiency can be improved. Thus, the rising time of the magnetic field can be shortened by expanding the magnetic gap width on the side separated from the face of the bias magnetic field generator 4 opposed to the medium 1, reducing magnetic coupling degree between the center york 5 and the outside york 6 and reducing self-inductance.
