Title: Air flow generating mechanism for use in pressure-reduced balanced heating apparatus
Inventor: KUBOYAMA NOBUYOSHI
IPC: F24J3/00
Filed: 1981-02-25
Abstract: PURPOSE:To render the distribution of temperature in an enclosed chamber uniform, by producing forced flow of air in the enclosed chamber. CONSTITUTION:A suction port 4 is opened at the central portion in the top plate of an enclosed, hollow chamber 1, and a rotatable means a consisting of rotatable blades 6 driven by a motor 5 is fitted in the suction port 4 for drawing air in the hollow chamber 1 to the outside and defining a frictional heat generating section A in the operational range of the means a. Further, rotatable blades 8 are arranged downward of the rotable means a with some spacing from the same to constitute a driven, rotatable mechanism Y which is turned by the viscosity of air drawn by the means a. The rotatable blades 8 discharges air in the hollow chamber 1 to the outside at the time of starting operation of the apparatus. However, when pressures on the outside and inside of the chamber 1 are balanced and heating process is started, they function to draw air upward at the central portion and to direct air downwardat the circumferential portion as shown by arrows in the drawing, so that forced convection of air is produced in the enclosed, hollow chamber.

IPC: G03G21/06
Filed: 1981-02-24
Abstract: PURPOSE:To destaticize the undesired part when an image is contracted, by using a variable mask utilizing a liquid crystal plate. CONSTITUTION:In case a copy original 62 is contract-projected a photoreceptor drum 2 through an optical system 64, the destaticization is carried out at the areas 56 and 60 to prevent the sticking of the undesired toner in the developing process. A liquid crystal plate 38 contains transparent electrodes 46a-46n plus 48a-48n, and thense electrodes are selected and receive the application of voltage. As a result, the areas 50 and 54 corresponding to the areas 56 and 60 respectively are made transparent, and an area 58 corresponding to a contracted picture part is made opaque respectively. Thus the destaticization is carried out to the areas 56 and 60 by the light passed through the transparent area 50 and 54 of the plate 38. The plate 38 is usable as a variable destaticizing mask according to the degree of contraction by properly selecting the electrode.

Title: Coding/decoding device
Inventor: TAKEDA HIDETOSHI
IPC: H04N1/12
Filed: 1993-02-15
Abstract: PURPOSE:To obtain a coding/decoding device which does not generate resonance at a step motor even when a data quantity for one line increases and a coding or decoding speed is slowed down by being provided with a conversion means, an activating means and a delay means, which are respectively specified. CONSTITUTION:A coding circuit 20 as the conversion means converts picture data read by a reading part 23 by a system corresponding to a prescribed standard. In this case, even when coding by the coding device 20 is delayed because the reading data quantity of an original is much, it does not lead a result that the rotation of the step motor 22 drops into a resonance band. Namely, in the case when coding is delayed and the rotation speed comes into the resonance band, CPU 15 of the activating means waits for the output of an actvating signal and executes delay. Thereby, the loss of synchronizm and the inversion of the moter are not caused by the resonance of the step motor 22 to always output a clear transmission image and to prevent the skip-reading of a line because of vibration.

Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To eliminate the unnecessary operations of a mouse cursor and to improve the working efficiency of the mouse cursor by switching the mouse cursor in a sequence that is set for every application. SOLUTION: An input device 3 gives a switching instruction of a mouse cursor to a multi-window system 21. Receiving the switching instruction, a system 23 which holds plural mouse cursors decides whether the application program name under operation is registered using a mouse cursor holding file 24. If the application program name is registered, it is decided whether a registration number to be processed is included in the mouse cursor registration number of the application program name. If a table that is coincident with the mouse cursor registration number of the application program name is confirmed, the mouse cursor coordinates of the registration number to be processed are sent to the system 21. Then the registration number to be processed is updated by adding 1 to the value of the said mouse cursor registration number of the table.

In this case, heat capacity of the casts 3, 3' must not exceed five times of heat capacity of a metal therein. If it is greatly exceeded, a material integrating a polarity column and a connection part and a connection spot between the connection part and the edges will fail.
