Title: Phase shifter
Inventor: HAMPEL KARL GEORG
IPC: H01Q3/32
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To obtain a radio frequency phase shifter to be mechanically or electromechanically controlled so as to be suited to application to a communication business. SOLUTION: This phase shifter 100 shifts the phase of a signal propagating through a transmission line by moving a conductive constituted object between the active line and ground face of the transmission line. The conductive constituted object is electrostaticly connected with the active line and ground face, and allowed to function as an electrostatic shunt on which the large part of the signals is reflected. The residual part of the signals is reflected on the terminated edge part of the transmission line, and substantially any signal loss can be prevented. Thus, the conductive constituted object is moved along the transmission line so that the phases of the whole reflected signals can be shifted.  This shifter 100 can be implemented by using a strip line, micro-strip, or coplanar waveguide transmission line structure supported by a voice or a substrate, or another pseudo TEM transmission line structure.

Title: Developing device for electrostatic recording
Inventor: SASAKI TAKAMORI
IPC: G03G15/09
Filed: 1985-11-08
Abstract: PURPOSE:To perform development faithful to an electrostatic latent image by making a smoke of a toner in the developing system using the one-component magnetic toner. CONSTITUTION:A magnet roll of a roll 11 is driven in the direction of an arrow by a motor or the like. The toner on a sleeve 8 is made into a chain-shape 21 and is formed along lines of the magnetic force, and the chain-shaped toner 21 is rotated by the magnetic force when magnetic poles of the magnet are moved. When the chain-shaped toner 21 is carried by the upper roll 11 and approaches a lower interlocking roll 12, a repellent is generated with the opposite magnetic field permeating the chain-shaped toner 21 by the magnetic field of the lower roll, and the chain-shaped toner 21 is broken to make a smoke of a toner 23. Since the magnetic attraction of magnetic rolls 11 and 12 does not reach the toner 23, a visible image faithful to the electrostatic latent image is obtained.

Title: Selecting device for working form of device containing cpu
Inventor: FUJISAWA MASAYUKI
IPC: G05B1/01
Filed: 1986-10-22
Abstract: PURPOSE:To realize selection of device working conditions in response to the degree of expertness of a user or necessity for change of the working conditions, by changing the set working conditions of a device containing a CPU by means of a switch. CONSTITUTION:The working conditions of a device containing a CPU are properly set by controlling plural input switches 10 from outside. While a clock switch 12 is operated to store fixedly the working conditions set previously by the switch 10. A memory 24 stores the set working conditions. A working state selecting means 32 selects the working state of the device containing a CPU in response to the operation of the switch 12 directly based on the contents set by the switch 10 in a release mode of switch 12 and then based on the set contents stored in the memory 24 in a fixed mode of the switch 12. Therefore the switch 12 is always kept closed as long as it is not needed to change the working conditions of the switch after the switch 10 is once operated by an expert. Thus an unskilled operator can perform measurement in a simple way.
