Filed: 1978-10-04
Abstract: PURPOSE:To facilitate thin forming by minimizing volumetric variations and by improving applicative ratio of cathode active material in such a way that after coating zinc over carbon fiber, sheet-shaped zinc sublimated is made into a cathode. CONSTITUTION:A cathode 4 is formed by punching out a sheet-shaped material which is sublimated after coating zinc over carbon fiber. A super-thin type battery is shaped in such a way that this is combined through a separator 6 with a discoid anode 2 which is punched out a sheet-shaped material made in such a way that silver peroxide or silver oxide is taken as main ingredient is added binder and mixedly kneaded to be a sheet formation. As carbon fiber, for example, it is obtained by gradually carbonizing superfine fiber which has acrylic resin and polyamide resin as main ingredients and superfine fiber which has polyamide resin as main ingredient, for which are used those with fiber in average value for the diameter of circa 100-200mum. Zinc is coated by evaporating, spattering, ion plating, etc. on the surface of the fiber, and further sublimated. This facilitates thin forming with merits of improving energy consistency, minimizing volumetric variations, equalizing diffusion of electrolyte, and improving applicative ratio of the active materials.

Title: Low temperature storage tank
Inventor: SAKURAI HIDEYO
IPC: F17C13/08
Filed: 1985-06-06
Abstract: PURPOSE:To prevent ejection of leak low temperature liquid to a ground surface, by a method wherein a seal plate, having an upper end formed integrally with the periphery of a bottom plate made of concrete, is buried in a ground, and the lower end of the seal plate is buried down to an underground water-bearing layer to watertightly isolate the outside of the bottom plate from underground. CONSTITUTION:In the outer peripheral end part of a bottom plate 11, a seal plate 13 is buried in a ground, and an upper end 13a thereof is buried in the under surface of the outer peripheral part of the bottom plate 11 for sealing. The lower end 13b of the seal plate 13 is buried down to depth by which is is lowered down to an underground water-bearing layer 14. Thus, even when RC concrete of the bottom plate 11 of a low temperature storage tank 10 happens to be cracked, temperature liquid is leaked to an underground occasioned by vertical extension of the crack, and the liquid is gasiified by a terretial heat, gas can not flow to a ground outside of the low temperature storage tank 10, and this prevents the gas from ejection from a ground surface.

Title: Ultrasonic type obstacle detection circuit
Inventor: HAYASHI FUSAO
IPC: G01S15/931
Filed: 1984-06-18
Abstract: PURPOSE:To enable better identification and decision, by employing the comparison of the transmitted frequency and the received frequency in a fixed period for distinguishing reflected ultrasonic waves from noises. CONSTITUTION:By a signal of a transmission command circuit 2, a reference pulse signal matched with the resonance frequency of a transmitter 5 from a reference pulse circuit 1 is sent to the transmitter 5 by an impedance matching with a driver circuit 4 through an AND circuit 3. An ultrasonic wave by a resonance vibration is generated in the transmitter 5 and transmitted in a specified direction. When encountering any obstacle in the course, the sound is reflected back and received with a receiver 6 to be shaped in the waveform with a waveform shaping circuit 8 via an amplifier 7. Then, the output of the circuit 8 is inputted into a terminal of a preset counter 9 to set an RSFF circuit 11 by a starting point signal. On the other hand, signal of a setter 10 is compared with a digital comparator 16 and mixing any noise will prolong the gate time of the FF11 so that no noise will not be outputted to the comparator 16 thereby enabling the distinguishing of noise from reflected wave.

Abstract: PURPOSE:To realize the small diameter of a cylinder and to function a device compatibly with a standard VTR, by providing different rotary driving devices for a rotary magnetic head in sections where the rotary magnetic head is brought and not brought into contact with the magnetic tape. CONSTITUTION:The rotary magnetic heads 13 and 14 are driven by the rotary driving means with different methods in a contact section and a non-contact section with the magnetic tape. Therefore, the rotary magnetic head 14 on the other side can be set so as not to be brought into contact with the magnetic tape when the rotary magnetic head 13 is brought into contact with it in spite of the winding quantity of the magnetic tape for the cylinders 1 and 2.

In such a way, it is possible to realize the small diameter of the cylinders 1 and 2 and also, to always bring only one rotary magnetic head into contact with the magnetic tape.
