Title: Electron lens
Inventor: TSUNO KATSUSHIGE
IPC: H01J37/153
Filed: 1979-05-31
Abstract: PURPOSE:To reduce S-shaped aberration of lens by using a triple magnetic pole electron lens for forming symmetrical magnetic field against a central magnetic pole under real image forcusing condition and exciting parameter of lens within predetermined range. CONSTITUTION:Magnetic poles 2, 3 are jointed at upper and lower ends of yoke 1 while a magnetic pole 4 is arranged between them. Exciting coils 5, 6 are contained in two hollow sections formed by the yoke 1 and the magnetic pole 4. The magnetic pole is vertically symmetrical against the center of the second magnetic pole 4 and has same diameter. The central portion of the second magnetic pole 4 is thined. When setting the exciting parameter SBU-1/2 (where S is the distance between magnetic poles, B is the strength of magnetic filed, and U is the acceleration voltage after correction) of said lens to be 0.35-0.5, minute focus distance fp1 and S- shaped aberration factor (DELTAS/r)2 are obtained, thereby the aberration is reduced and the distance between the lens and film can be shortened.

Title: Article processing apparatus
Inventor: HIROBE NORIFUMI
IPC: B65B57/10
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To improve accuracy of processing by a method wherein a material having small reflectance of light is used at the surfaces of apparatuses in an image pickup area of an image pickup apparatus that is used for applying specified processings to articles with recognition of the articles made, based on pick-up image information picked up by the image pickup apparatus. SOLUTION: An illuminating apparatus 1 is constructed, for instance, of a number of LED's 1a for emitting infrared rays and a diffusion member 1b arranged in front of the LED's, and irradiation of the infrared rays can be made in an area broader than an image pickup area A. A conveyance surface 105 in the image pickup area A is formed of a resinous member 106 having a small reflectance of light with a coarse surface for diffuse reflection of the infrared rays. On the other hand, a frame 108 of a weighing conveyor 100 is made of a stainless steel plate, and a low-reflectance material such as, for instance, a mat black tape 109 is stuck to the surface of the image pickup area A on the frame 108.

Title: Traveling motor controller for battery forklift
Inventor: NAKAKITA OSAMU
IPC: B66F9/24
Filed: 1995-03-27
Abstract: PURPOSE: To reduce battery consumption without causing the problem of insufficient climbing power or maximum speed by determining a current being fed to a traveling motor based on a current command value determined from the r.p.m. of motor and an extracted function, and an input power to battery and then feeding the traveling motor with the current thus determined. CONSTITUTION: A function extracting means 13 extracts a function of r.p.m. of motor/current command value and a current value operating means 14 determines a current command value from the r.p.m. of motor detected by a rotation sensor 6 and an extracted function and delivers the current command value to a power conversion circuit 8. A current being fed to a traveling motor 4 is then determined based on the current command value and a power being inputted from a battery 1 and the current thus determined is fed to the traveling motor 4. Since the function of r.p.m. of motor/current command value includes a current command data satisfying the climbing power in low speed region and a current command value data satisfying the maximum speed in high speed region, battery consumption can be reduced while eliminating the problem of insufficient climbing power or maximum speed.

CONSTITUTION:When both TV receivers I and II are set at the broadcasting receiving modes, the signals of the output signal lines l11 and l12 of a detection circuit 23 to 1s, and the signals of output signal lines l1, l3, l6, and l8 of a logic circuit 24 go to 0s, and the signals of l2, l4, l5, and l7 go to 1s, and diodes D11, D21, D32, and D42 are turned ON, and diodes D12, D22, D31, and D41 are turned OFF. Consequently, the signals from antennas 1 and 2 are supplied to the receiver I, and the signals from antennas 3 and 4 are supplied to the receiver II. When the receiver I is set at another mode and the receiver II is set at the broadcasting signal receiving mode, the signal of the signal line l11 goes to 0, and the signal of the l12 goes to 1, therefore, the signals of the signal lines l2, l4, l6, and l8 go to 0s, and the signals of the signal lines l1, l3, l5, and l7 go to 1s. Therefore, the signals of the antennas 1-4 are supplied only to the receiver II, and no antenna signal is supplied to the receiver I.
