Title: Production of oxyalkylene polymer
Inventor: ISAYAMA KATSUHIKO
IPC: C08G65/00
Filed: 1981-05-20
Abstract: PURPOSE: To produce a high-MW oxyalkylene polymer at low cost and easily, by reacting an alkylene oxide addition polymer with a specified amount of a polyfunctional halogen compound.  
     CONSTITUTION: An alkylene oxide addition polymer is reacted with 1/8W5 times, by mol, polyfunctional halogen compound to increase the MW of the addition polymer. The above product is then reacted with an allylic halide compound to produce a high-MW oxyalkylene polymer containing terminal allylic olefin groups. It is preferred for the production of said high-MW polymer that the halogen compound has the greatest possible functionality. Moreover, the MW of the polymer formed has a maximum value at a specified amount of a halogen compound used. That is, the maximum MW polymer is obtained by using the polyfunctional halogen compound in an amount corresponding to about 1/NW 2/N time, by mol, the formed polymer present at the end of the polymerization.

Title: Drive circuit, display device and display method
Inventor: KONOUE AKIHIKO
IPC: G09G3/28
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption at a display operation time by beforehand changing a weight level in a display period of a sub-field based on luminance information of a display part beforehand detected from an image signal and display operating with the display pulse of the weight level. SOLUTION: Analog video signals G, B, R are A/D converted by an A/D converter 1200 answering to 9 bits to be made a digital signal of 8 bits by a γ correction circuit 1201. This signal is stored in a frame memory 15, and the luminance of the signal is counted by a weighting counter 1202. The weighting counter 1202 counts the signals of respective sub-fields with the counters, and shifts a level of a binary code one bit each by an adder answering to the bits, and an adder output becomes a field integration luminance signal. This field integration luminance signal is added by the adder 1203 to obtain a contrast control signal 1204. This contrast control signal 1204 is inputted to a selection circuit 19 to select a ROM of a contrast level from a ROM group for a third electrode.

Title: Regulating device for humidity in refrigerator
Inventor: HARA AKIRA
IPC: F25B21/02
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To facilitate dehumidification at a low temperature by a method wherein heaters are arranged around moisture absorbing fins, connected to an electronic refrigerating element, to excite the heaters to heat when a temperature around the moisture absorbing fins is lowered to a value lower than a predetermined value while the heating of the heaters is stopped when the temperature is higher than the predetermined value. SOLUTION: Heaters 8 are provided around inside moisture absorbing fins 4, connected to an electronic refrigerating element 3, and when a temperature around the inside moisture absorbing fins 4 is lowered to the degree of 10 deg.C, for example, it is detected by a temperature sensor 7 and the heaters 8 are excited to heat while the heating of the heaters 8 is stopped when the temperature around the inside moisture absorbing fins 4 has raised to the degree of 20 deg.C, for example. According to this method, the electronic refrigerating element can be left in the operated condition at all times while the freezing of condensate on the inside moisture absorbing fins can be prevented under this condition. When the condensate on the inside moisture absorbing fins is supposed to be frozen, the frozen condensate can be defrosted immediately when the heaters are operated.  Accordingly, dehumidification in the refrigerator can be effected at all times without intercepting the cooling effected by the electronic refrigerating element.

Title: Photoresponsive film and production thereof
Inventor: SHIMIZU SHIGERU
IPC: G02F1/13
Filed: 1990-03-27
Abstract: PURPOSE:To obtain the photoresponsive film which does not require a power source, is light in weight and can be formed as a thinner film by dispersing liquid crystals and azo benzene derivatives into a high-polymer medium and developing a light shielding effect or recording effect by the irradiation with light. CONSTITUTION:The liquid crystals 3 and the azo benzene derivatives 11 which are precipitated in the form of droplets 2 are dissolved into the high-polymer medium 1. After this medium 1 is crimped between transparent electrode plates 7, a polymn. reaction is effected in the state of impressing an AC electric field by a power source 9 to form the transparent film in which the arrangement of the liquid crystal 3 in the droplets 2 face one direction. The transfer of geometric isomers from a cis type to trans type rises in the dissolved azo benzene derivatives 10 and the directivity of the liquid crystal 3 facing the one direction is disturbed if this film is irradiated with light 13. Consequently, a refractive index difference arises between the liquid crystals 3 and the high- polymer medium 1. A clouding state is thus generated and is utilizable for light shielding and recording.

Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To set restrictions on photographing operation from the viewpoint of protecting privacy by setting a photographing area where a specified object exists as the area where a telephotographing action is restricted and setting an allowable zoom restriction value on a telephoto-side within this restricted area. SOLUTION: A camera is pointed at the vicinity of the object whose telephotographing is desired to be restricted by executing a panning action by operating a joystick within the movable range 80 of the optical axis of the camera. For example, when the telephotographing of a private house 82 is restricted, the camera is turned in a left rotating direction with the central position CP of the angle of all panning actions as a reference and pointed at a position PA on this side of the house 82. Next, a focal distance is set to be the allowable maximum focal distance in a more left side area than the panning position PA by operating a zoom operation lever. Then, the panning position PA of a boundary in the telephotographing restricted area and the maximum focal distance are stored in a RAM by depressing a limit button.  On and after it, the zoom value is restricted in a more outside area than the panning position PA.

IPC: F02M31/08
Filed: 1980-06-10
Abstract: PURPOSE: To make it possible to heat a suction air tube by opening the end of a intake air subchannel provided on an exhaust channel side, and heating the intake air of the intake subchannel through an intake air heating member installed in the intake subchannel in a cross flow type internal combustion engine.  
     CONSTITUTION: An intake air subchannel 52 is installed on an exhaust channel side 32. The end of the channel 52 is opened inside a main intake air channel 28 so that the end may be directed at a combustion chamber 16. The wall of an intake subtube 38 communicating to the intake subchannel 52 turns a heating member 46 of an intake tube. The diameter of the intake subchannel 52 is smaller than that of the main intake channel 28. The intake air passing through the intake air subchannel 52 increases its speed. The fuel injected from a fuel injector 54 flows with the high speed intake air into the combustion chamber 16, which makes the atomization better. The intake air going through the intake subchannel 52 is heated with the heating member 46 of the intake air tube heated with a hot exhaust. Therefore, the injected fuel is satisfactorily atomized.
