Title: Magnetic rotary encoder
Inventor: MAZAKI AKIO
IPC: H03M1/24
Filed: 1985-06-12
Abstract: PURPOSE:To eliminate the need for alignment by writing a magnetic pattern after a rotary disc not magnetized yet is mounted as a rotary encoder and detecting the angle based on the pattern. CONSTITUTION:An insulation board fixed from a rotary disc at a prescribed minute gap, amorphous magnetic thin film 9 formed radially on the insulation board at a prescribed pitch around the rotary shaft and conductive thin film 7 are provided. In driving the rotary shaft 2, the magnetic flux interlinking the amorphous magnetic thin film 9 of the magnetic head 4 is changed by the magnetic pattern on the rotary disc 3. When the magnetic flux is inverted, a pulse voltage rising rapidly, a so-called Matteucci voltage by the Matteucci effect is obtained. The signal is amplified by the number of radial lines of the magnetic thin film 9 of the magnetic head 4 and a signal is produced between terminals 8a and 8b. In waveform-shaping the voltage, a pulse voltage corresponding to the rotation of the rotary disc 3 is obtained.

Title: Washing machine
Inventor: OZEKI SUKEHITO
IPC: D06F23/04
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To eliminate uneven rinsing in spin-drying and rinsing. SOLUTION: A water passage 31 protruded inside from a balancer of a washing and spin-drying tub 12 is equipped along the whole circumference on the upper end rim of an outer tub 11, water pouring ports 34 are formed at proper intervals on the lower face of the water passage 31, and a water receiving part 32 to receive water poured from a water outlet is equipped on a part of the water passage 31. When water is poured in the water receiving part 31, the water filter flows into the water passage 31 and poured into the washing and spin-drying tub 12 through the water pouring ports 34. Thus, water is showered on washing in the washing and spin-drying tub 12 from the whole circumference. Consequently, water is more uniformly penetrated into each washing than when water is poured rotating the washing and dehydrating tub 12 to improve unevenness of spin-drying and rinsing.

IPC: C22C5/10
Filed: 1984-06-21
Abstract: PURPOSE:To obtain the titled material having low and stable contact resistance by adding prescribed percentages of Cd, Mn and one or more among In, Sn, Sb, P, Ti and Zr to Ag so as to control the stickiness of an Ag-Cd alloy and to improve the wear resistance. CONSTITUTION:A sliding contact material is obtd. by adding 1-15wt% Cd, 1-7wt% Mn and 0.5-5wt% one or more among In, Sn, Sb, P, Ti and Zr to Ag. In the material, 0.01-0.5wt% Fe group element may be substituted for part of said added elements. Since the sliding contact material is hardly stuck and has superior wear resistance, when the contact chips 1a of a commutator 1 for a small-sized motor are made of the sliding contact material, the contact chips 1a produce very little dust due to wear during sliding along brush contacts 3. No noise is generated and a beneficial effect such as low and stable contact resistance is shown.

Title: Method for measuring hydrogen absorption-discharge equilibrium pressure of hydrogen-storing alloy
Inventor: ONISHI KEIZO
IPC: C01B3/00
Filed: 1985-06-14
Abstract: PURPOSE:To measure a hydrogen absorbing and discharging amount, by pressurizing or depressurizing certain N-th pressurized hydrogen so that the sum of the hydrogen amount corresponding to the difference between the hydrogen absorption or discharge equilibrium pressures of (n-1)-th and (N-2)-th pressurized hydrogen and the absorbing discharging hydrogen amount of the (N-1)-th hydrogen to perform the absorption or discharge of N-th hydrogen. CONSTITUTION:(N-1)-th measurement is performed by introducing hydrogen of an absorbing reservoir tank 2 into a specimen chamber 3 to absorb the same with a specimen 4. If there is no change in pressure even after the elapse of several min, the detection pressure of a pressure sensor 5 at this time is set to hydrogen absorbing equilibrium pressure. Next, in N-th measurement, the sum of the hydrogen amount corresponding to the difference between (N-1)-th and (N-2)-th hydrogen absorbing equilibrium pressures and the hydrogen amount absorbed with the specimen 4 in the (N-1)-th measurement is set to the hydrogen atom in N-th measurement and hydrogen is introduced into a specimen chamber 3 from a tank 2 in the amount corresponding to the pressure difference of the tank 2 corresponding to said set hydrogen amount to perform the absorption of hydrogen. At the point of time when the pressure of the specimen chamber 3 became constant, an absorbed hydrogen amount is measured from the amount of hydrogen introduced from the tank 2 and the N-th and (N-1)-th equilibrium pressures. In the same way, a discharged hydrogen amount is measured.
