IPC: F24F13/20
Filed: 1995-03-08
Abstract: PURPOSE: To effectively prevent contamination of a periphery of an air blowoff port without bringing suction air containing contaminants into direct contact with the periphery of the blowoff port from within a room to keep the design in the room in a good state. CONSTITUTION: In a blowoff port, in which there are provided a plurality of cone vanes 18a, 18b, 18c which are formed in an approximately hollow truncated cone shape to form an air passage so as to diverge toward downstream side of an outer frame 12 and which are mounted coaxially with the outer frame 12, proximal portions 19a, 19b, 19c on the upstream side of the vanes 18a, 18a, 18c are oriented at least in parallel, in cross section, with a flow of air.  Since there is no plane radially protruding for supporting the vanes, there is no hindrance to air flow near the inlet of the vanes so that the air flows from the proximal end portions of the vanes in the straight form, and hence the air flows while being restrained by a diverging part and separation of air from the inner surface of the vanes is not produced and diverging effect is accelerated, thereby preventing contaminants from attaching to the top surface of the periphery of the blowoff port.

Filed: 1986-04-07
Abstract: PURPOSE:To calculate the amplitude value with high accuracy and to increase the calculation speed by constituting an amplitude value arithmetic system where a correction arithmetic formula is added to a formula representing the principle of the area method and appropriate constants and multiplication are applied. CONSTITUTION:The absolute value of the instantaneous digital value obtained by sampling the AC electric energy in a fixed cycle and converting it into a digital code is calculated for addition by an amount equal to 1/2 cycle to obtain the 1st value. Then this 1st value and the 2nd value obtained by extracting the minimum value out of the absolute value used for the calculation of the 1st value are multiplied by a prescribed constant respectively. These multiplied 1st and 2nd values are added together. In other words, the correction arithmetic, i.e., the minimum value extracting arithmetic processing 8 is added to the absolute value extracting arithmetic processing 6 equipment to the conventional area method and the continuous 6-data addition processing 7. Thus it is possible to greatly reduce the error of the arithmetic result of amplitude value caused by the conventional area method.

IPC: G03G15/14
Filed: 1995-04-04
Abstract: PURPOSE: To obtain an optimum exposure according to the kind of transfer material by controlling the light quantity of an exposure means, in accordance with the kind of transfer material. CONSTITUTION: When a toner image is formed on the surface of a photoreceptor drum and the transfer material P ejected from a paper feeding cassette 6 reaches a transfer part 7, a light transmittance sensor 32 measures the light transmittance of the transfer material P. This light transmittance sensor 32 is constituted of light emitting and receiving parts and when the light is emitted from the light emitting part, the light transmits the transfer material P and reaches the light receiving part. The rate of attaindance is used as the light transmittance. The light transmittance detected by the sensor 32 is imparted to a control part 20. The control part 20 obtains the optimum exposure corresponding to the kind of transfer material by referring to an exposure table 21, to transmit a control signal to a variable power source 16b.  This power source 16b drives a light source 16a according to the control signal from the control part 20. Thus, the exposure with the light transmitting the transfer material P and reaching the surface of the photoreceptor drum becomes suitable.

Title: Pressure-sensitive copy paper
Inventor: MATSUYAMA HIROTAKE
IPC: B41M5/124
Filed: 1989-03-29
Abstract: PURPOSE:To prevent an offset phenomenon due to strike-through and to prevent developed color fog at the time of printing by using paper containing a filler composed of a laminar silicate having a specific mean particle size and a two- layered structure and forming a slurry showing specific pH in a specific amount or more as base paper. CONSTITUTION:Base paper containing a filler composed of laminar silicate having a mean particle size of 0.5-5mum and a two-layered structure and forming a slurry having pH of 7 or less in an amount of 20% by wt. of a total filler is used. By this method, extremely excellent pressure-sensitive paper effectively improved in printing opacity and generating no developed color fog at the time of printing is obtained. When the mean particle size of the filler is below 0.5mum, a problem such that the yield of the filler in the base paper is lowered (retention inferiority) or a paper strength is lowered is generated and said filler is unsuitable practically and, when said particle size exceeds 5mum, no desired opacity is obtained. When laminar silicate having the two-layered structure is not used and the pH thereof exceeds 7, the improvement effect of developed color fog at the time of printing can not be expected.
