Title: Production of light-colored metal salt of rosin
Inventor: MAEDA MASAO
IPC: B01J23/46
Filed: 1994-12-19
Abstract: PURPOSE: To obtain the subject metal salt useful as a raw material for a tackifier for a tacky adhesive, having excellent color tone, smell and stability, by subjecting a specific stabilized rosin and a prescribed metal compound to a salt formation reaction. CONSTITUTION: This metal salt is obtained by subjecting (A) at least one metal compound of Li, Na, K, Mg, Ca, Zn and Al, more preferably the chloride, nitrate, acetate, oxide or hydroxide of the metal and (B) a stabilized rosin having <=1 Gardner color scale to salt formation reaction. The component B is obtained by passing a gum rosin, a wood rosin or a tall oil rosin through at least one stabilizing reaction process selected from disproportionation reaction, hydrogenation and dehydrogenation and a purifying process in an arbitrary order. For example, the example of the component B includes a colorless rosin obtained by dehydrogenating a purified disproportionated rosin in the presence of a dehydrogenation catalyst (preferably palladium, rhodium or platinum-based catalyst) under the pressure of <10kg/cm<2> .

Title: Turbocharger provided with electric rotary machine
Inventor: HARA SHINJI
IPC: G01D5/245
Filed: 1987-12-28
Abstract: PURPOSE:To make it possible to precisely detect the position of a magnetic pole of a rotor by providing a permanent magnet to be detected, on a rotary shaft, and by providing a means for detecting a rotating position of the permanent magnet to be detected and a means for shielding the detecting means in a stationary part. CONSTITUTION:When a turbo-charger is driven so that a compressor impeller 1 and a rotor 3 are rotated through a rotary shaft 4, a detection permanent magnet 52 attached to the forward end of the rotary shaft 4 by means of a nut 41 is also rotated so that a magnetic sensor 62 detects a variation in magnetic field and delivers a signal to a control circuit. The signal delivered at that time corresponds to the rotating position of the magnetic pole of the rotor 3, and accordingly it is possible to precisely detect a variation in a magnetic field and the phase thereof during rotation of the rotor 3. Further, since variations in magnetic field due to the permanent magnet of the rotor 3 and the coils in the stator 7 are restrained by a shield plate 8, it is possible to obtain a detection signal having a satisfactory S/N ratio.

Title: Fall preventive screw dispensing with female screw
Inventor: OTSUKI RYUICHI
IPC: F16B35/00
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To prevent a screw from coming off, and prevent the screw from being loosened in removing the screw from a work. SOLUTION: A screw 10 consists of a head part 11 and a leg part 14 having a tapping screw part 15 which is integrated with the head part 11 and forms a female screw in a lower hole of a work at the tip. The tapping screw part 15 has 2-3 threads, and a thread-free part 17 of the diameter equal to or less than the diameter at the bottom of thread of the screw part 15 is formed continuous thereto, and the thread of the same pitch as that of the tapping screw part 15 is formed on a tightening part 18 between the screw-free part 17 and an under head part 13. When the screw is used for the work, no special working to prevent the screw from coming off from the work is not necessary, and when the screw is loosened, no screw comes off from the work and no screw is lost.  Because the thread of the tightening part of the screw brings deformation to the female screw of the work, no screw is loosened even when the work is vibrated.

Title: Television camera device

IPC: G03B7/095
Filed: 1999-11-26
Abstract: PROBLEM TO BE SOLVED: To obtain an appropriate video signal level for a subject at all times which is a photographing target, when the auto iris of a television cameral device is operated. SOLUTION: In a conventional auto iris, because a lens iris follows over almost the entire range, from opening to almost fully reduced of a disphragm aperture, an appropriate video signal level cannot be obtained for a subject if the subject situation is not appropriate. Therefore, an operation range is made variable by arbitrarily setting the upper and lower limits of the operation range of the lens iris when the auto iris of the television camera device is operated, so that an appropriate video level can be obtained at all times for the target subject.
