Title: Manufacture of glass stem
Inventor: SAEGUSA MASUMI
IPC: H01J9/30
Filed: 1990-01-17
Abstract: PURPOSE:To form a required header with a single unit of stem fabricating device and allowing formation on a stem continuously by expanding the top of ring-shaped header into a trumpet form prior to formation of the stem, and enlarging the gap between the top of the header and each lead. CONSTITUTION:A ring-shaped glass header 53 is heated and softened, and its top is expanded into a trumpet form. Now the gap between the header top and each lead 3 is enlarged, and the top of the header 53 is no more likely to tumble to the lead side, so that the glass is precluded from attaching to elsewhere than that part necessary for airtight sealing of the lead 3. The softened header 53 can be welded to the lead 3 certainly by pressing a roller 41 thereafter to the periphery of the header. Thus a header in specified form can be formed with a single unit of stem fabricating device along with formation of the stem without use of nay header forming device proprietary for the purpose.

Title: Wind mill
Inventor: EBINA KATSUO
IPC: F03D3/06
Filed: 1980-01-26
Abstract: PURPOSE: To attempt to improve the operational efficiency of the wind mill by rotating the wind mill vanes by 1/2 rotation per one revolution of the wind mill.  
     CONSTITUTION: The wind mill is constituted by wind mill vanes 6 controlled by synchronizing mechanisms 2W5, and 7 rotating around a rotary gear 1. When the wind mill vanes 6 receive wind force from a wind direction 8, the rotation of the wind mill vane is delayed by 1/2 rotation per one revolution of the rotary gear 1, whereby it is possible to suitably change the rotation of the wind vanes. When the wind direction 8 changes, the fixed gear 1 is rotated in the opposite direction at an angle twice the angle changed, whereby the angle of the wind direction 8 is made coincident with the angle of the wind mill vane 6. Accordingly, the height from the ground and the diameter can be designed arbitrarily, and necessary parts including a synchronizing mechanism 9 can be all disposed at the peripheral part, and this type of the wind mill does not undergo limitations as received in the propeller type wind mill.

Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To escape the deterioration of voice quality by integrating multiple coded data into cells, and transmitting it to an asynchronous transfer mode(ATM) transmission path only when sound/silence information multiplexed into the multiple coded data indicates sound. SOLUTION: A voice encoder 10 of a voice encoding part 1 converts an input voice into each kind of coded data.

IPC: H03L7/10
Filed: 1992-01-22
Abstract: PURPOSE:To reduce the time till phase synchronization is locked after application of power by using a voltage detection circuit, a switch control circuit and a switch so as to charge rapidly a low pass filter output signal. CONSTITUTION:A voltage detection circuit 12 compares an optional DC voltage (h) with a low pass filter output signal (c) and outputs a voltage detection signal (d) when the signal (c) gets higher than the voltage (h). A switch control circuit 13 receives the power-on clear signal (g) and the voltage detection signal (d) and outputs a switch control signal (e) closing a switch 14 till a level of the low pass filter output signal (c) reaches a usual operating potential from a potential at application of power. The witch 14 makes the power supply conductive to the signal (c) for a time in putting only a signal (e), resulting in charging a capacitor 11 rapidly. Thus, the time till the circuit reaches the usual operating voltage after application of power is reduced and the time required for phase synchronization is quickened by the time reduction.

Abstract: PURPOSE:To improve the transmitting efficiency and the accuracy of a step motor by composing a rotor of a cylindrical drive shaft and a permanent magnet to be engaged with a threaded shaft, and increasing the lateral width of the magnet longer than the lateral width of a stator. CONSTITUTION:A stator 3 is fixed to a casing 2, a rotor 4 is composed of a permanent magnet 9 and a cylindrical drive shaft 8, and the inner periphery of the shaft 8 is engaged with a threaded shaft 7. An output shaft 12 is pressed by a coiled spring 17 to the rotor 4, a valve mechanism 15 is provided in the intermediate of the shaft to close or open a passage 14 in response to the rightward or leftward operation. When the stator 3 is energized, the rotor 4 is spirally moved along the shaft 7. Thus, the shaft 12 is moved to open or close the passage. The lateral width of the magnet 9 is longer at least by the movable distance of the rotor 4 than that of the stator 3 so that the magnet 9 is always disposed at the stator 3. Since the rotor 4 directly operates the shaft 12, its loss is reduced and its error is decreased.

Abstract: PURPOSE:To cool the whole inner tank to a uniform temperature by fitting fins for heat-exchanging with the evaporated low-temperature gas on the inner-wall surface of the inner tank. CONSTITUTION:A container of a low-temperature liquid 1 such as liquid helium, liquid nitrogen is constituted with an inner tank 2, a heat insulating layer 3, and an outer tank 4, and fins 6 made of a material having good conductivity such as Cu, Al in a shape capable of having a large surface area such as sheet foil, mesh are fitted to the inner-wall surface of the inner tank 2 by welding, soldering, etc. The evaporated low-temperature gas efficiently cools the whole inner tank 2 via the heat exchanging fins 6, and the evaporation speed from the container is suppressed.
