Title: Small-sized motor with battery lifetime predicting function
Inventor: ABE SHIYUUZOU
IPC: H02K16/02
Filed: 1981-01-12
Abstract: PURPOSE:To perform the predicting display of the lifetime of a battery by arranging a rotor which drives a battery lifeime predicting display board between the poles of a stator in addition to a rotor which drives a wheel train of a watch. CONSTITUTION:When an inversion pulse signal is supplied to a coil 4, rotors 8, 9 stepwisely rotate in directions of arrows. A gear 14 of the rotor 8 drives a gear 15 and further drives hour and minute hands via a wheel train. At this time the gear 16 of the rotor 9 drives a gear 17 to alternately present the color classified parts on the upper surface of the gear 17 in a window hole 18, thereby carrying out a second flash. While the second flash can be observed through the hole 18, the voltage of the battery is sufficient and means that a watch normally operates. When the voltage of the battery is then lowered, since the minimum starting voltage of the rotor 9 is set larger than the rotor 8, the rotor 8 will still operate to drive the watch, but the rotor 9 will stop rotating. Thus, the second flash is vanished in the hole 18, thereby predicting the vicinity of the lifetime of the battery.

Title: Gutter trough antenna
Inventor: KOBAYASHI ATSUSHI
IPC: H01Q1/44
Filed: 1989-01-10
Abstract: PURPOSE:To prevent the reduction in the antenna gain due to rainfall by providing an antenna element to a cover plate converted to an aperture of a gutter trough main body. CONSTITUTION:A cover plate 2 covering part of the opening of a gutter trough main body 1 is fitted to the gutter trough main body 1 whose upper face is, e.g. opened and whose cross sectional shape is nearly U of channel shape. An antenna element 6 made of a loop shaped conductor circulating the circumference of the cover plate 2 is buried. Through the constitution above, rain water is led into the gutter trough main body 1 through a throughhole 5 at rainfall and does not almost flow on the cover plate 2. Since a gap is formed between the water face of the rainfall flowing in the gutter trough main body 1 and the cover plate 2, mutual action between the rain water being a conductor and the antenna element 6 does not almost exist. Thus, the reduction in the antenna gain due to rainwater is prevented.

Abstract: PURPOSE:To form a distortion on the electric field distribution between a filament and a control electrode, accelerating the focusing of emission electrons to a passing hole, and improve the radiation quantity of emission electrons to a luminous body by providing a focus accelerating electron on the control electrode. CONSTITUTION:The voltage applied to an X control electrode 9a and a Y control electrode 9b is made 10V, and the voltage applied to a focus accelerating electrode 9c is made 8V. Thereby, a distortion is formed on the electric field distribution E as if it is undulated, and the electric field distribution E near a passing hole 10 is curved to the outside (downward).

Accordingly, the electron density of the emission electrons (e) in the passing hole 10 can be remarkably improved, and the brightness of a luminous body 2 can be increased.
