Title: Nonaqueous secondary cell
Inventor: FURUKAWA SANEHIRO
IPC: H01M10/052
Filed: 1987-09-08
Abstract: PURPOSE:To improve the charge and discharge cycle characteristic by using an active material made of lithium or lithium alloy as a negative electrode and a mixture of manganese dioxide and lithium salt and phosphorus pentaoxide and baked and quickly cooled as a positive electrode active material. CONSTITUTION:In a nonaqueous secondary cell using lithium or lithium alloy as a negative electrode active material, a mixture of manganese dioxide and lithium salt and phosphorus pentaoxide and baked and quickly cooled is used as a positive electrode active material. Manganese dioxide and lithium hydride and phosphorus pentaoxide are kneaded in the argon atmosphere, for example, then baked in the air and quickly cooled in the excess cold water and filtered and dried. The powder thus obtained and a conducting agent and a binding agent are mixed as a positive electrode black mix and pressure-molded for use. The material thus baked and quickly cooled is in a nearly amorphous state and abounds in reversibility, thus the charge and discharge cycle characteristic is improved.

Title: Key driving device
Inventor: SAKAI KIMIO
IPC: G10H1/00
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To make possible effectively using magnetic force. SOLUTION: Plural keys 14 are provided turnably on an upper surface side of a key board chassis 12. A key rear end member 31 is provided on the upper surface rear end part of the key 14, and a permanent magnet 32 is provided on the rear end surface of the key rear end member 31. An electromagnet 33 is provided backward the permanent magnet 32 so as to oppose to it. Then, when a current is supplied to the electromagnet 33, the electromagnet 33 gives one magnetic pole of the permanent magnet 32 repulsion for turning the key 14 in the key depressive direction, and gives other magnetic poles attracting force for similarly turning the key 14 in the key depressive direction. Thus, the magnetic force is used effectively compared with the case when the key 14 is turned in the key depressive direction only by the repulsion or the attracting force between the electromagnet 33 and the permanent magnet 32.

IPC: H04H1/00
Filed: 1992-08-25
Abstract: PURPOSE:To reduce the number of terminals and to decrease the number of parts by allowing a first capacitor connected to a detecting signal output terminal to be served also as both of FM and AM low-pass filters and allowing a second capacitor to be served also as both of a high-pass filter for removing FM sound and the AM low-pass filter. CONSTITUTION:A detecting signal output terminal 24 and a detecting signal input terminal 25a are connected by a coupling capacitor 37, and the terminal 24 and a detecting signal input terminal 25b are connected by a low-cut capacitor 38. Further, the terminal 24 is grounded through a capacitor 34. At the time of FM reception, the capacitor 34 forms an LPF about at a cut-off frequency 300kHz with the output impedance of a detection circuit. This FM detecting signal is inputted through the coupling capacitor 37 to the terminal 25a. On the other hand, since a switching circuit 18 is changed over to the ground side at the time of AM reception, the LPF is composed of the output impedances of the capacitor 38 and terminal 24. Therefore, the number of terminals is reduced and the number of parts is decreased.

Date Jul. 7, 1983.The liquid crystal display cell (21) indicates the date in an aperture situated at 12 o'clock. The hour wheel (31) and the center wheel (29) present coaxial pipes which pass through the dial and bear hour and minute hands. These wheels are driven by a wheel-train (30, 28, 27) actuated by the stepping motor (25) which receives its pulses from the circuit (23) controlled at a frequency of 1 Hz for example by the quartz (48). The 24-hour wheel (33) bears a contact element (46) which, once per revolution, grounds the terminal (47). The pulse which results therefrom is transmitted to a counter incorporated in the circuit (23). This counter controls the decoding circuit which controls the display cell (21). To effect the setting of the date, the stem (35) is brought into its intermediate position (II). The contact element (40) borne by the yoke (38) then grounds the terminal (41), which causes in the circuit (23) the emission of pulses at a frequency of 1 Hz which controls a repeated and rapid change of date.
