Title: High-frequency hybrid integrated circuit
Inventor: NITTA NORIO
IPC: H01P5/08
Filed: 1993-05-10
Abstract: PURPOSE:To reduce mutual inductance in the vicinity of an integrated circuit, and to improve high impedance at the time of high frequency of a wire wiring section by lowering the height of the section of the wiring section having a vertical component to an element surface positioned on an integrated circuit pattern. CONSTITUTION:Vertical-component mounting wiring height on the element surface 21 of an integrated circuit is decreased for reducing the magnetic field 32 of a height component generated in a circuit wiring in the element surface 21 of the integrated circuit. 10mumphi-50mumphi is used as a bonding wire diameter, and wiring height is set in the wire diameter at a minimum and in the length of one side of an electrode pad at a maximum and inhibited in 10mum-100mum at that time. An insulating-coated wire having sufficient dielectric strength is further employed. Bonding is conducted by a wire 23 having low loop height. Accordingly, an integrated circuit element 11 is formed in arrangement and a shape best for reducing mutual inductance, thus acquiring a high-frequency hybrid integrated circuit having a mounting section corresponding to high frequency.

Title: Antenna having high sensitivity and wide band
Inventor: MIZUNO AKIKO
IPC: H01Q21/20
Filed: 1982-07-31
Abstract: PURPOSE:To ensure a wide band and high gain for the titled antenna, by realizing free circulation and exchange of air between the inside and outside of a pipe and then inducing a high frequency electromagnetic field in the inside of a secondary element with high efficiency. CONSTITUTION:A main element 7 is formed by connecting circularly a copper pipe containing many small holes and then fixed at the middle part of a main post 12. The insulated lead wire in the element 7 is connected to the insulated lead wire in the post 12. A secondary element is formed by connecting several aluminum pipes 14 having a smaller diameter than an aluminum pipe 13 and many small holes to the pipe 13 having many small holes by means of a copper joint 16. Several pieces of such a secondary element are connected onto the element 7 via copper joints 8. Those small holes of each pipe facilitate free circulation and exchange of air at the inside and outside of the pipe to keep an equal dielectric constant and permeability at the inside and outside of the pipe. As a result, a high frequency electromagnetic field is induced with high efficiency at the inside of the secondary element in a weak electric field. Then said electromagnetic field is induced at the element 7 with high efficiency. Thus it is possible to obtain >=50dB high gain over a 10-100MHz band with use of a 80cm main post, a 60cm circular diameter of the element 7 and >=5 secondary elements respectively.

Title: Latent image forming method
Inventor: IWASAKI SHINICHI
IPC: G03G15/00
Filed: 1979-10-16
Abstract: PURPOSE:To achieve the improvement in gradation reproducibility by controlling not the irradiation quantity of an original but the simultaneous entire surface exposure according to the densities of the original. CONSTITUTION:This is a method of forming latent images by applying entire surface exposure simultaneously with charging and image exposure, wherein simultaneous entire surface exposure L is set by the selection of charging conditions or grid setting conditions or photoreceptor so that when it is made zero by closing a shutter 3 the original density versus latent image potential characteristics shown in the curve 2 are obtained. If it is set in this way, in the case of a pale character original, the shutter 3 is closed, whereby the easy-to-see images of high contrast in which the difference in the latent image potential between the characters and the white ground is large like 2 are obtained. In the case of a photograph or the like, the simultaneous entire surface exposure L is increased by opening the shutter 3 to correspond original density versus latent image potential 1 to 1, whereby the images faithful to the original are obtained. For an ordinary original, the exposure L is so controlled as to obtain the curve 1. In this way, the gradation reproducibility may be improved.
