IPC: G05B13/02
Filed: 1992-11-19
Abstract: PURPOSE:To make possible stable temperature control, to reduce an overshoot amount, to shorten setting time and to improve the accuracy of temperature control by controlling heating/cooling sensitivity and making heating capacity and cooling capacity equal. CONSTITUTION:A temperature control system controls the heating and cooling of a controlled system 2 with a heating/cooling enable heat source element 1, and the cooling/heating enable element 1 has difference in the heating capacity and cooling. A temperature PV of the controlled system is measured by a measuring instrument 3, and the measured result is inputted to a subtracter 4 and a controller 5. The subtracter 4 calculates difference (e) between a set temperature SV and the measured temperature PV and inputs it to the controller 5. The controller 5 decides a manipulated variable Ce of the cooling/heating enable element 1 corresponding to the difference (e) and outputs it to a heating/cooling changeover switch 6. A cooling/heating switching signal SL is a switching signal to be decided corresponding to the positive/negative polarity of the difference (e) and it is decided whether the manipulated variable outputted from the controller 5 is outputted to an HG adjusting part 7 or to a CG adjusting part 8.

Title: Manufacture of polypropylene
Inventor: SAITO JUN
IPC: C08F10/06
Filed: 1988-12-08
Abstract: PURPOSE:To produce a polypropylene which is highly crystalline and has good transparency by polymerizing propylene using a preactivated catalyst obtained by reacting a Ti-containing solid catalyst component with an organoaluminum compound and a halogen-substituted styrene. CONSTITUTION:A combination of a titanium-containing solid catalyst component and an organoaluminum compound, and if desired, an electron donor is polymerized with a halogen-substituted styrene of the given formula (wherein X is halogen; and R<1> is H or alkyl) in an amount of 0.001-100g per g of the titanium- containing solid catalyst component to produce a preactivated catalyst. Propylene alone or propylyene and another alpha-olefin are polymerized using the above catalyst.

IPC: G03B17/24
Filed: 1990-11-19
Abstract: PURPOSE:To perform proper photography by pressing a magnetic head against the surface of a film continuously even after the film travels by one frame if continuous photography is judged, and moving the magnetic head away from the film surface after a picture of one frame is taken at the time of one-frame photography. CONSTITUTION:When the continuous photography is performed, the photography is carried out while the magnetic head 10 is pressed against the surface of the film 2 without being moved away from the film surface every time the film is fed by one frame, and consequently the magnetic head 10 is pressed against and moved away from the surface of the film 2 repeatedly in a short time to eliminate trouble such as the unstableness of the position of the film 2 and a shift in focus position. Then the film 2 is fed intermittently by frames in the film passage 4 consisting of an aperture 3 and a pressure plate 6 on a camera main body side and when the film 2 is wound, the magnetic head 10 records exposure conditions, trimming information, etc. Further, the film 2 is prevented from deflecting by holding the head 10 in a stand-by state at the time of one-frame photography. Thus, the flatness of the film 2 is maintained and focusing on a photography expected surface is securely performed.

Title: Read-only memory device
Inventor: SUZUKI HIROSHI
IPC: G11C17/18
Filed: 1991-10-30
Abstract: PURPOSE:To improve an unstable state in the logical state of bit lines while avoiding increase in power consumption and to prevent an erroneous operation. CONSTITUTION:The logical state of the bit line BL is outputted as a bit data by a sense amplifier 30. The logical state of the bit line BL is turned to a floating state in which either an H-state or an L-state is dependent on a precharged electric charge. As the logical state of the bit line BL is prevented by a bit data holding means 10 from becoming unstable due to such floating state, the logical state of the bit line BL is held. Also, as the holding of the bit data holding means 10 is reset by a reset means 20 at the time of a precharge operation, a through current does not flow even if the logical state of the bit line BL is varied.
