Abstract: PURPOSE:To prepare the titled copolymer free from stickness and useful as a packaging material, etc., stably and economically, with low by-production of amorphous polymer, by carrying out the copolymerization of propylene and other alpha-olefin in two steps each characterized by a specific composition and specific conditions. CONSTITUTION:Propylene is copolymerized with other alpha-olefins (e.g. hexene-1) using a catalyst system comprising diethylaluminum chloride-titanium trichloride, etc. supplying hydrogen gas to the system, in two steps under the following conditions. The value of formula log(MFRB/MFRA) is adjusted to 0.7-6 wherein MFRa is the melt flow rate of the copolymer produced by the first step copolymerization and MFRB is the melt flow rate of the copolymer produced by the second step copolymerization. The content ratio of the alpha-olefin in the copolymer produced by each step[(M)A/(M)B]is adjusted within the range of 1.1-6. The  weight ratio (mA/mB) polymerized in each step is adjusted to 1/9-9/1.

Title: Uv detector
Inventor: NAKAMOTO AKIRA
IPC: G01N30/74
Filed: 1985-05-16
Abstract: PURPOSE:To prolong the life of a lamp, by changing the discharge current of a lamp as a light source corresponding to the use sensitivity of an ultraviolet (UV) detector. CONSTITUTION:A lamp lighting circuit 12 is equipped with a constant current circuit 14 and a discharge current setting circuit 16. The circuit 14 receives set voltage from the circuit 16 at the discharge current setting terminal 18 thereof and the current flowing to a deuterium lamp 2 is detected by a current detecting resistor R1 and a constant current is supplied to the lamp 2 through a diode D so as to make the voltage drop Vr of the resistor R1 equal to set voltage. A discharge current set value by the circuit 16 is automatically changed with the range of a detection system changed over by a range change-over circuit 40. By this method, because the life of the lamp 2 is prolonged and the lamp current is made large only at the time of high sensitivity use, a current equal to or more than a rated current is caused to flow without shortening the life of the lamp to enable the use of a detector in a small noise level state.

Title: Propeller shaft
Inventor: KAGEYAMA HAYASHI
IPC: F16F15/12
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To regulate a torsional vibration characteristic in an extensive range by furnishing a viscous fluid damper, a torsion bar arranged in parallel with the damper and a stopper to limit the maximum twist angle of the torsion bar between a pair of relative rotating members respectively connected to a pair of torque transmission members. SOLUTION: Torque input from one of a pair of torque transmission members 3, 5 on a propeller shaft 1 is transmitted to the other of the torque transmission members 3, 5 through a viscous fluid damper 7 and a torsion bar 9 arranged in parallel. At this time, when a twist angle of the torsion bar 9 becomes large, an arm 33 of the torque transmission member 3 knocks against a knocking part 65 and a stopper 11 works, and torque larger than this is transmitted through the stopper 11. That is, the stopper 11 limits the twist angle of the torsion bar 9 and protects it, but until the stopper 11 works, oscillation is absorbed by viscosity of viscous fluid by the viscous fluid damper 7 and twisting of the torsion bar 9.

Title: Dressing method of grinding wheel
Inventor: MIYAKOSHI KOICHI
IPC: B24B53/02
Filed: 1985-05-17
Abstract: PURPOSE:To reduce initial wear of a grinding surface of a grinding wheel and improve working efficiency by decreasing or increasing a dressing speed as a dressing stroke length increases when a dresser applied to the grinding surface of the grinding wheel in rotation is moved forward and rearward. CONSTITUTION:In a first forward and rearward process, when a rearward dressing speed V1r is decreased to one-half of a forward dressing speed V1f, the number of crests traversed by a dresser 2 in the rearward process is twice as many as the case in which the rearward dressing speed is equal to the forward dressing speed. Thus, crests made in the forward process is shaved off more fine to decrease the height of the crests as a whole. However, a level L of roots is always kept constant because the amount of wear of the dresser 2 is ignorably small. Further, in a second forward and rearward movement of the dresser 2 when a forward dressing speed V2f is decreased to the dressing speed V1r and a rearward dressing speed V2r is decreased to the dressing speed V2f, a shaves surface is so finished that the height of the crests thereon is decreased as a whole. As a result, an initial wear is greatly decreased, a frequency for dressing a grinding wheel is decreased, and a working efficiency is increased although a cutting quality is a little decreased.

Abstract: PROBLEM TO BE SOLVED: To provide an incinerator which can contribute to the reduction in the release of a harmful substance attributed to an exhaust gas and to the conservation of the amount of an auxiliary fuel used by securing a high combustion efficiency. SOLUTION: Cross pieces 8 are disposed on furnace beds 2 and 3 arranged vertically on two levels and at an upper part of an incinerator and members entangled with numerous whiskers 15, 16 and 17 made of stainless steel are arranged between the upper cross pieces 11 and 12 and the lower cross pieces 13 and 14 of the respective furnace beds 2 and 3 and on the cross pieces 8 so that the glowing whiskers 15, 16 and 17 is kept in touch with an unburned gas in a wider surface area to achieve a higher combustion efficiency. A clearance between the whiskers 15 of the upper furnace bed 2 is made more rough than that on the lower furnace bed to let a matter to be incinerated reducing with combustion drop onto the lower furnace bed 3.  This secures better air permeability on the furnace beds 2 and 3 to achieve a complete combustion of the matter to be incinerated thereby eliminating unburned matter left in incineration ash while making the whisker 17 on the cross pieces 8 play a role of a filter of a flue gas duct 7.
