Filed: 1985-05-01
Abstract: PURPOSE:To accomplish sure separation of sheets to be fed by installing No.2 group of nozzles so that the air streams therefrom are concentrated, and thereby enhancing the separation efficiency of the uppermost lying sheet from the other. CONSTITUTION:The No.1 group of nozzles 15, 15 are oriented in parallel with the surface at the top of the sheets 2 stacked on a sheet feed tray 1, and air streams from these nozzles put the leading edges of the sheets 2 lying at the top afloat and separate these sheets from each other. Then the suction force of a blower 10 is transmitted to an attraction hole 7 through a vacuum box 8 so as to attract the uppermost sheet 2a to a transport belt 6 at its oversurface. The air streams a from No.2 group of nozzles 16a-16c jet out so as to be concentrated to one point, and the velocity is converted into pressure to generate a stagnation pressure. This will boost the pressure between the uppermost sheet 2a and its subsequent 2b to provide sure separation of the sheet 2a, 2b through the action of this pressure.

Title: Method for measuring irregularity of material by ultrasonic image
IPC: G01B17/00
Filed: 1992-03-19
Abstract: PURPOSE:To measure the irregularity of the surface of a material by setting a standard surface, emitting an ultrasonic wave thereto, generating a change of waveform by the reflected wave from the material surface and the reflected wave through the standard surface, and converting, on the basis of this, the irregular state of the material into an ultrasonic image. CONSTITUTION:A standard surface is set to the surface of an irregular material. In setting the standard surface, a flat plate is arranged opposite to the surface of the irregular material. An ultrasonic wave is emitted to form the reflected wave from the material surface and the interference wave of the reflected wave from the standard surface, and on the basis of this, the irregular state of the material is converted into an ultrasonic image. As the plate, a glass plate or metal plate is used. When the ultrasonic wave is emitted to a material 1 set in water and a plate 2 closely adhered thereto through a prove 3, for example, the reflected wave (a) from the material surface and the reflected wave (b) from the standard surface of the plate 2 are obtained, and these reflected waves are mutually interfered to generate an interference wave. By converting the irregular state into the ultrasonic image on the basis of this, the irregularity can be clearly measured and displayed.

Filed: 1983-05-26
Abstract: PURPOSE:To shorten the first copy time after the change of copy magnification by accepting a print key during the change of copy magnification of an optical system to perform the copying operation from the copying operation start to an operation preceding original scanning. CONSTITUTION:Even while a copying machine magnification set key 41 or 42 is turned on to move a projection lens 6, a print key 66 is accepted, and the operation (copying pre-operation) before movement of an original platen out of a series of copying operations is exectured during movement of the projection lens 6 simultaneously with turning-on of the print key 66, and the original platen is started to move simultaneously with the time when the projection lens reache to a prescribed position and is stopped, and the copying operation is completed. The wait time which the user senses is a time X from turning-off of a paper feeding clutch to the end of movement of the projection lens. Consequently, the wait time is shortened considerably in comparison with the wait time in a conventional copying machine where a time Y for lens movement is included in the wait time, and thus, the efficiency of business is improved.

Filed: 1994-04-08
Abstract: PURPOSE:To secure safety by controlling in such a way that the water content concentration of fleon substitute washing liquid in a washing processing tank is constantly higher than the fixed value. CONSTITUTION:A water content concentration control means 60 outputs a command signal to actuate a demineralized water make-up pump 95 so as to add demineralized water in a demineralized water tank 94 to fleon substitute washing liquid in a washing processing tank 90 when the value of water content concentration computed by a water content concentration computing means 40 is less than the allowable water content concentration previously inputted by an allowable value input means 61. In the case of the water content concentration value computed by the water content concentration value computing means 40 exceeding the specified set value by the addition of demineralized water, the water content concentration control means 60 outputs a command signal to stop the operation of the demineralized water make-up pump 95, and the water content value computed on the basis of infrared absorption data is constantly monitored by a water content concentration display means 50 and the water content concentration control means 60.

Title: Processing method for edition number of program
Inventor: IGARASHI HARUO
IPC: G06F9/06
Filed: 1990-04-11
Abstract: PURPOSE:To reduce the labor required for control of the program edition number by checking the largest edition number among those source programs stored in a directory and then deciding and registering the value larger than the checked largest edition number as the edition number of an executing form program. CONSTITUTION:When the source programs are changed, each of source programs P1 - P3 undergoes the edition number control where the edition numbers of the programs are changed in the order of their changes in accordance with a change history. When an executing form program is produced, the edition number control is automatically carried out so that the value larger than the largest edition number among the source programs serving as the component elements of the executing form program is defined as the edition number of the executing form program. In this case, the edition number alignment processing is applied together with the executing for program production processing. Thus a program developer is not required to manually check the edition numbers of all source program. Then the labor required for control of the program edition number is extremely reduced.
