Inventor: OOSAWA MASANORI
IPC: C08F4/02
Filed: 1979-01-25
Abstract: PURPOSE: To prepare an α-olefin polymer having improved crystallinity and bulk density, by using a catalyst comprising an aluminum compound, and electron donor and a composition provided by pulverizing a magnesium compound together with an organic acid ester, an unsaturated monomer,  hydrocarbon, etc. and treating the mixture with a titanium compound.

Title: Production of oxide single crystal
Inventor: TAKAHASHI AKIHIRO
IPC: C30B29/30
Filed: 1990-01-16
Abstract: PURPOSE:To effectively control shape of a solid-liquid interface in melt in pulling up of crystal to improve quality of a single crystal by growing an oxide single crystal from melt in a crucible with making a ratio of a crystalline diameter of pulledup single crystal to an inner diameter of the crucible in a specific range. CONSTITUTION:An oxide single crystal is grown with making a ratio of a crystalline diameter of pulled-up single crystal to an inner diameter of a crucible to 0.65-0.75 in growing the oxide single crystal from melt in the crucible by a pulling-up method. Said method is utilizable to all of various methods in the pulling-up method, thus an oxide single crystal such as LiNbO3 or LiTaO3 is advantageously obtained. For <=0.65 said ratio of a crystalline diameter to an inner diameter of the crucible, a shape ratio (a/L) at a solid-liquid interface of a single crystal 8 becomes smaller than -0.05 and a shape of the interface becomes concave (upwardly protruding), thus crystallinity is decreased. On the other hand, for >=0.75 of said ratio, crystallinity is also decreased, while the shape of the interface is downwardly protruding, thus improving of quality of the resultant single crystal 8 is difficult.

Title: Full automatic chain stretching device of chain type
Inventor: SUZUKI KIYOSHI
IPC: F16H7/08
Filed: 1986-01-16
Abstract: PURPOSE:To automatize chain stretching by providing a sensor on the tip end part of the indication rod of a chain slackness measuring device, and driving a chain stretching device with an actuator operated by the signal of said sensor when the amount of slackness is increased. CONSTITUTION:When the amount of slackness of a chain 10 is increased during operation, a pipe 2 which is connected to a chain retaining lever 4 is lowered while an indicating rod 3 which is connected to a chain retaining lever 5 is lifted up. Accordingly, distance between the tip end of the indicating rod 3 and the sensing end of an approach switch 1 is varied. When this variation is sensed, a signal is issued and a pilot motor provided on a chain stretching device is driven rotating an intermediate shaft 9, to stretch the chain 10. As the chain 10 is stretched, the levers 4, 5 are restored, the indicating rod 3 is lowered, and the distance between the rod 3 and the switch 1 is restored stopping the pilot motor. Thereby, the chain can be automatically restored to a stretched condition at all times, preventing inconveniences due to the slackness of the chain.

Title: Magnetic shield device for cathode ray tube
Inventor: KAWAMOTO HIROSHI
IPC: H01F7/02
Filed: 1990-01-18
Abstract: PURPOSE:To reduce the influence of a magnetic field to a cathode ray tube and to prevent noise from being generated by protruding the front edge of a magnetic shield main body around the cathode ray tube rather than the front panel of the cathode ray tube for more than a fixed distance and arranging a magnetic path changer on the front edge. CONSTITUTION:Around a cathode ray tube 6, a shield main body 7 composed of a soft magnetic plate substance such as dim steel, soft steel, silicon steel, permalloy and amorphas metal, etc., is arranged. The front edge of the shield main body 7 is protruded rather than the front panel of the cathode ray tube 6 for more than 20mm at least. At the front edge of the shield main body 7, the magnetic path changer such as a permanent magnet 8 or U-shaped object 9 is arranged. The magnetic path changer concentrates the back and forth magnetic flux toward the front panel of the cathode ray tube without affecting the cathode ray tube 6 and changes the direction of the concentrated magnetic flux. As a result, a shield effect is improved, a magnetic shield material can be arranged in a conventional enclosure and outer appearance is made satisfactory as well.

Title: Output buffer circuit
Inventor: SUGIYAMA NOBUYUKI
IPC: H03K17/12
Filed: 1988-01-14
Abstract: PURPOSE:To increase the number of the simultaneous operations of output buffers by providing electronic circuits which set prescribed MOSTs in conducting states when the capacity of the transistors (MOST) are deteriorated. CONSTITUTION:The potential of an output terminal N3 in a first electronic circuit 3 comes to a low level when a P-MOST is deteriorated, and the potential of an output terminal N4 in a second electronic circuit 4 comes to a high level when an N-MOST is deteriorated. When the P channel and N channel are deteriorated in the transistor, the P-MOST QP3 and N-MOST QN3 come to the conducting state, and an output current is increased for P-MOST QP2, QP3 and N-MOST QN2, QN3. Thus, the necessity to enlarge the size of an original transistor is eliminated in consideration of the reduction of the output current due to radiator and the like, and a peak current when the output buffers are simultaneously operated can be reduced, whereby the number of simultaneous operations of the output buffers can be increased.

Title: Multipurpose tool
Inventor: CHIYAARUZU ETSUCHI GURAHAMU
IPC: B25F1/04
Filed: 1985-01-18
Abstract: A multi-purpose tool has a handle (12) with a shaft (14) affixed thereto and a cylinder assembly (16) disposed to longitudinally slide on the shaft between positions in which the shaft is fully extended to a working position or fully retracted to a loading position. While in the loading position, a cylinder having a plurality of chambers housing different tips (18) may be rotated about its axis, which is offset from the shaft, until the desired tip aligns with and engages the shaft in coupling engagement. The shaft is then extended to the working position thus extending the tip and permitting free rotation of the working tip for use in performing work on a workpiece. Changing the tip requires retracting the shaft, rotating the cylinder to engage the next desired tip, and extending the shaft back to its fully extended position. The multi-purpose tool may be attached to a power tool for power driven rotation.

Abstract: PROBLEM TO BE SOLVED: To prevent the frequency of oscillation output of a frequency synthesizer from fluctuating when a ringer is ringing or the vibrations are applied. SOLUTION: The chip parts 37 constructing an oscillation tuning circuit part of a voltage controlled oscillator of a frequency synthesizer are mounted on a printed circuit board 36. When a ringer 18 rings to notify an incoming call, the vibrations of the ringer 18 are transmitted to the parts 37 through the board 36. As the parts 37 are covered with silicone 38, the vibration energy is absorbed by silicone 38. Thus, it's possible to prevent the characteristics of parts 37 from being varied by the deformation of the parts 37 which are caused by the vibration energy.
