Patent EP-0290183-A1 (EP)
Inventor: SHIMIZU TETSUO C O PIONEER ELE
IPC: H04N9/873
Filed: 1988-04-26
Abstract: In a PAL video signal processing device a first circuit (41/141,1) receives a video signal or a colour component signal of a video signal and provides a first output, and a second cicuit (42/142,2) receives the output of the first circuit and provides a second output. One of the first and second circuits includes means (41/141,42/142) for phase-shifting, or delaying by a period of time corresponding to a phase difference of 180° of the colour subcarrier signal, the signal applied thereto; and has a switch (1,2) for selectively outputting one of the phase-shifted or time delayed signal and the non-­phase-shifted or non-time delayed signal. The other of the first and second circuits includes a delay circuit (42/142,41/141) for delaying the signal applied thereto by the horizontal scanning period (1H); and has a switch (2,1) for selectively outputting the delayed or non-delayed signal. A logic circuit (16) controls the switching of the switches (1,2).

Title: Polymerization of ethylene
Inventor: FUJITA TAKASHI MITSUBISHI PETR
IPC: C08F110/02
Filed: 1988-08-15
Abstract: A process for the polymerization of ethylene comprises bringing ethylene or ethylene and at least one α-olefin in contact with a catalyst comprising a metallocene compound of a transition metal selected from Groups IVB, VB and VIB, an aluminoxane and a silicon compound having an Si-O-C bond for polymerization. The use of the silicon compound having an Si-O-C bond in the catalysis by a combination of a metallocene compound and an aluminoxane results in the production of ethylene polymers having a lower melt flow rate (MFR) than those produced similarly except for the silicon compound not being used.

Abstract: A modified supported catalyst for polymerizing alpha-olefins, for example, ethylene, is prepared by combining a chromium compound-containing catalyst with a modifier which is an oxide of an element of Group II A of the Periodic Chart of the Elements. The resulting modified catalyst composition, when used to polymerize alpha-olefins, produces polymer resins having higher values of High Load Melt Index (I₂₁) than catalyst compositions without the modifier. 
     There is also disclosed a process for polymerizing alpha-olefins, at relatively lower temperatures than was heretofore possible, to obtain resins of relatively high HLMI, using the above-identified modified catalyst composition. The resulting polymers can be used for the fabrication of blow-molded products, e.g., household and industrial containers.

Abstract: A system for correcting laser output of a CNC laser machining apparatus in which a numerical controller (CNC) and a laser machining apparatus are coupled together. Corrective means (11) determines correction coefficients for mak­ing an instruction value of the laser output coincide with the actual laser output when the laser is started. The practical out­put is measured by an output measuring device (33) at predetermined time intervals and is controlled by instruction con­trol means (13) such that the difference becomes zero between the corrected instruction value and the practical laser output. Long-term variation in the output is corrected when the laser output rises and short-term variation is corrected dur­ing the practical machining operation, so that the laser output is properly produced.

Abstract: A linen drier (tumbler) contains, in a machine housing (1), a rotating drum (2) which is surrounded by a jacket-like hot-air circulation space (3). Hot air flows continuously through the hot-air circulation space (3) and executes essentially a circular flow. All or some of this hot air repeatedly passes through a heating device (7), so that it is maintained at an essentially constant temperature. Moreover, the hot air passes through perforations in the drum (2) and the linen tumbled in the drum. As a result of the contact of the linen with the hot drum wall and the hot air passing through the drum wall, the water contained in the linen evaporates and is drawn off axially together with the hot air in the "moisture core". <IMAGE>

Abstract: The invention relates to a mixed-type compressor where each compression stage comprises a main impeller (8) with a diameter increasing in the upstream-downstream direction at the input and at least one fixed rectifier (13, 14) at the output. This compressor is remarkable in that an additional movable impeller (10) is fitted between the main impeller and the fixed rectifier, said impeller (10) being integral in rotation with the main impeller and of the axial vane type with a higher camber at the top than at the bottom so as to reduce the radial gradient of the total flow pressure between the input and the output of said vanes. Such an additional impeller reduces the flow distortion at the output of the rotor and thus also reduces the losses in the fixed rectifiers while producing a maximum pressure ratio.

After a second X-ray image this procedure is repeated, but the movement of the mark (12) in the different directions on the monitor (11) or top (3) does not take place independently in the three spatial directions (x, y, z) but is instead derived from the value obtained at the end of the first positioning operation.
