Title: Alkaline battery
Inventor: NAKATANI KATSUNORI
IPC: H01M4/24
Filed: 1983-02-28
Abstract: PURPOSE:To prevent any expansion and breakage of an alkaline battery by absorbing hydrogen gas generated from the positive electrode either in the last stage of the electric discharge or during the over-discharge by using at least one metal hydride to make the positive active material. CONSTITUTION:A positive mixture 2 containing mixture consisting of FeTi powder and silver oxide as an active material and subjected to heat treatment in hydrogen gas, is pressed and molded in a metallic exterior case 1 also serving as a positive terminal: the positive mixture 2 is composed of 1.0wt% FeTi, 97.0wt% silver oxide and 2.0wt% graphite. the thus obtained body is combined with a separator 3, a nonwoven fabric 4 and a gel-like negative electrode 5, thereby constituting a button-type alkaline battery. As a result, hydrogen gas generated from the positive electrode 2 in the last stage of the electric discharge or during the over-discharge is absorbed by FeTi which is a metal hydride, thereby enabling the internal space to be effectively utilized by using the positive active material of the same capacity as the negative electrode. Besides, any expansion and breakage can be effectively prevented.

Title: Rotation monitor device for internal pump
Inventor: FUKASE KAZUO
IPC: G01P13/04
Filed: 1994-03-02
Abstract: PURPOSE:To confirm the rotary direction of an internal pump while measuring the rotational speed thereof even at the time of a low speed by detecting the reflected light from the stripe like band reflecting part provided in outer circumference of a rotary part and continuously outputting a pulse like signal. CONSTITUTION:The light of a light source 28 passes through a spectroscope 27 to emit from the leading end of an optical fiber sensor 25. When wide and narrow non-reflecting parts 22, 23 of a stripe-like band are positioned in front of the leading end part of the optical fiber sensor 25, light is absorbed and, when wide and narrow reflecting parts 24, 24a are positioned, light is reflected. The reflected light passes through the spectroscope 27 to be converted into an electric signal by a light receiver 29 and the electric signal is transmitted to a monitor means. When an internal pump is rotated clockwise, a narrow pulse-like signal and a wide pulse like signal are successively generated and, when the internal pump is rotated counterclockwise, a wide pulse-like signal is generated first. By this constitution, the rotary direction of the internal pump can be easily confirmed. Since a pulse-like signal appears widely (narrowly) when the rotational speed of the internal pump is slow (fast), the rotational signal can be measured by detecting the width of the pulse-like signal.

Filed: 1986-02-19
Abstract: PURPOSE:To increase operating speed in a memory-system mainly comprising a RAM by integrally incorporating a memory circuit and a logic circuit onto the same semiconductor chip while using a complementary signal as a signal between these memory circuit and logic section. CONSTITUTION:A logic section 1 such as an address latch circuit is mounted at the pre-step of a RAM section 2 and a logic section 3 such as an error correction circuit at the post-step of the RAM respectively. Output signals having low amplitude at the final step of an internal logic circuit 12 for the logic section 1 are transmitted directly over the RAM section 2. The output signals are outputted as complementary signals ai, -ai to the RAM section 2 at the post-step from the logic section 1 at that time. With the RAM section 2, an input buffer can be omitted because the address signals are transmitted as the complementary signals from the logic section 1, and the complementary signals ai, -ai fed from said logic section 1 are inputted directly to a decoder circuit 21. Since the complementary address signals are inputted, data signals read from a memory array 22 are outputted directly to a circuit at the post-step by a sense gate 23.

Title: Oscillation measuring device
Inventor: ASARI TOSHIHIRO
IPC: G01H17/00
Filed: 1985-02-21
Abstract: PURPOSE:To measure the oscillation in the device which scans on a target with a simple constitution by shaping an oscillating waveform detected, when an electron beam intersects an edge body, to a pulse state, and measuring the pulse width. CONSTITUTION:An electron beam from an electron gun 1 is line-scanned on a Faraday Cup 7 with a low speed. By this scanning, the electron beam is intersected with an edge body 8, however, at this time, when there is the oscillation from a mirror tube or the oscillation of a stage, the beam which enters into the Cup 7 oscillates, and therefore the output signal of a beam current detector 9 becomes a periodic alternating waveform. The waveform signal is shaped to a pulse state by means of a wave-shaping circuit 10, and is supplied to an AND circuit 11 to which clock pulse signals are supplied. Accordingly, the clock pulse signals of half-wave length are outputted from the circuit 11 every half cycle. The clock pulses for the half cycle are counted by a counter 13. Since the counted value is corresponding to the time of the half cycle of the previous oscillation, the frequency due to the oscillation of the mirror tube and the stage is determined from the counted value.
