Title: Washing method for automatic washing machine
Inventor: OKADA TSUTOMU
IPC: D06F33/02
Filed: 1993-05-27
Abstract: PURPOSE:To sufficiently submerge laundry in a washing machine in which the water level is set in accordance with a volume of laundry so as to wash and rinse the laundry, by washing the laundry by a predetermined time after water is fed, and by restarting the water feed if the water level is lowered below a predetermined water level. CONSTITUTION:When the operation of a washing machine is started, water is fed up to a load detecting level which is lower than a water level during washing, and after water is fed by a predetermined energizing period, a motor 5 is normally and reversely rotated at predetermined intervals so as to normally and reversely rotate agitating blades 4. In this arrangement, the motor 5 serves as a generator when it is deenergized, and a load value of the laundry is calculated from an a.c. current generated by inertial rotation of the motor at that time. Water is further fed up to a water level corresponding to the load value, and the washing operation is restarted, Further, after a predetermined time (about 40sec) elapses from the time of starting of the washing operation, the operation of the agitating blades 4 is stopped, and a degree of lowering of the water level is measured at that time. If the degree of lowering of the water level exceeds a predetermined value, the water level is changed to a maximum water level, and water is fed up to the water level before washing is restarted.

Filed: 1991-05-30
Abstract: PURPOSE:To provide a printed wiring board for enabling a highly reliable packaging circuit device for obtaining a required junction strength to be constituted while restricting or preventing a solder bridge at the time of soldering of a connection lead entirely. CONSTITUTION:In a printed wiring board 4 where a plurality of pads 3 for connection for performing solder connection of a plurality of leads where a flat-package type surface mount parts have are formed on a main surface, a width in length direction where a connection lead of the pad 3 for connection is in contact is made narrower than that of the connection lead. With this configuration, a spacing of the pad 3 for connection in width direction can be made wider, thus enabling a connection failure such as generation of a solder bridge to be eliminated entirely. Also, since a strong solder fillet is easily formed between the pad 3 for connection and the connection lead, thus enabling a fully large joint strength to be maintained.

IPC: G02F1/1365
Filed: 1985-06-11
Abstract: PURPOSE:To improve a display characteristic and to facilitate production by laminating a bus bar electrode layer and picture electrode layer spaced from each other at a spacing part on the surface of an insulating substrate, laminating a non-linear characteristic layer on the spacing part and on the part near the spacing part and further laminating a conductor part thereof. CONSTITUTION:This liquid crystal cell has the picture element electrode layer 2 formed of ITO, etc. and the bus bar electrode layer 3 on the insulating substrate 1. The spacing part 4 is the spacing part between the layer 2 and the layer 3. The non-linear characteristic layer 5 and the conductor layer 6 are provided to said spacing part. The spacing part 4 is determined mainly from the ease of fine working and is about 10-50mum. About 10mum squre is usually enough for the crossing area of the layer 5 and the layer 2 or the layer 3. The occupying area of the layer 5 or non-linear element can be thereby made relatively small. Just two layers of masks are required when the layer 3 and the layer 2 are formed of the same kind of transparent conductive material. the stage is thus made simpler. Silicon and silicon carbide are more preferable in terms of the ease of fine working as the material for forming the layer 5.
