Patent JP-H063942-A (JP)
Title: Developing device
Inventor: MATSUURA MASAHIKO
IPC: G03G15/08
Filed: 1992-06-17
Abstract: PURPOSE:To prevent the lowering of image density even in the case of consecutively printing a solid black image and to always obtain a stable image having appropriate density by providing a magnetic member near an opposed part to a sleeve inside a toner supply roller. CONSTITUTION:The toner supply roller 9 is arranged at a very small distance apart from the sleeve 4, and rotated in a direction shown by an arrow (b) by a driving source, then the magnetic member 10 is fixed at a position opposed to a supplying and recovering area X in a non-rotating state inside the roller 9. In the area X, magnetic field is generated between the magnetic pole of a magnetic roller 6 opposed to the area X and the magnetic member 10 housed inside the roller 9. Therefore, developer held by the sleeve 4 is influenced by the magnetic field and spread toward the outer periphery of the sleeve, and widely brought into contact with the roller 9. Thus, the toner carried to the area X is efficiently scraped in the developer and supplied to the sleeve 4.

Title: Micro-relay
Inventor: UENO YOSHIHIRO
IPC: B81B3/00
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To improve contact stability by forming a recess, to which opposed tip edges of stationary contacts are overhung, between a pair of stationary contacts juxtaposed on the upper face of a stationary substrate and by forming an inclined face on the contact face of the movable contact. SOLUTION: A stationary substrate 10 defines a stationary electrode and stationary contacts 13, 14 on the upper face of a single-crystal silicon substrate 11 through an insulating film 15. The stationary substrate 10 also defines a recess 11a at approximately its center. Opposed tip edges of the stationary contacts 13, 14 are overhung to the recess 11a. The movable contact 27 has tapered faces 27a, 27b freely contacting with/separating from the stationary contact 13, 14. The opposed tip edges of the stationary contacts 13,1 4 are overhung to the recess 11a so that the movable contact 27 pressurizes the stationary contacts 13, 14 inwardly in the recess 11a after contacting with the stationary contacts 13, 14.  As a result, even if the film thicknesses of the stationary contacts 13, 14 show dispersions, the movable contact 27 surely contacts with the stationary contact 13, 14 and the stable contact state is ensured.

Title: Fuel cell generation system
Inventor: YAMADA HIROKO
IPC: H01M8/04
Filed: 1984-07-25
Abstract: PURPOSE:To improve the efficiency of a fuel cell generation system by effectually utilizing exhaust energy in the system by installing an air compressor which is directly connected to both a steam turbine driven by steam produced in a cooling loop and a gas turbine driven by excess air supplied from an air electrode. CONSTITUTION:Heat produced by the reaction of a fuel cell 1 is used to evaporate cooling water into steam which is then sent into a steam separator 2. Excess steam produced by evaporation of cooling water is supplied into a steam turbine 17 through a steam line 20 and used to drive an air compressor 18. Excess air remaining after the reaction of the fuel cell 1 is supplied into a gas turbine 16 through an excess air line 19 and used to drive the air compressor 18. The air compressor 8 works to increase the pressure of air to an operation level by using the power produced by the gas turbine 16 and the steam turbine 17 and to send the compressed air to the air electrode 1b of the fuel cell 1. Because of the above structure, it is possible to recover the power necesary for compressing air in the system.

The refrigerant joins in a second refrigerant joining device 23 and is returned into a compressor 1 through the check valve 24, a third pressure reducing device 8 and an indoor side heat exchanger 9. A second pressure reducing device 25 will never pass the refrigerant since the resistance of a second pressure reducing device 25 is high. Upon heating operation, the refrigerant from the compressor 1 passes through an indoor side heat exchanger 9 and is returned to the compressor 1 after being reduced in the third pressure reducing device 8 and the second pressure reducing device 25. Only the reducing device 22 is connected to the outlet port of the heat exchanger 21 whereby troubles upon brazing can be reduced and the pressure reducing device 25 can be united.

Filed: 1987-06-24
Abstract: PURPOSE: To calculate a mutual correlation coefficient by a simple circuit in the mutual correlation calculating circuit of a passive sonar receiver by normalizing a mutual correlation function by the mean square value of the mean level of two input signals.  
     CONSTITUTION: Right and left received beam outputs y(t) and x(t), respectively, set in respective bearings are multiplied by each other in a first multiplier 1, integrated in integrator 2 and a mutual correlation function ϕ xy(τ)  is calculated. On the other hand, the received beam outputs y(t) and x(t) are added to each other in an adder 3 to obtain a mean level, which is squared in a multiplier 4. The mean square value of the mean level of two input signals y(t) and x(t) is obtained by integrating the output of the multiplier 4 in an integrator 5. The mean square value is inputted to divider 6 and the mutual correlation function ϕ xy(τ)  is normalized by the mean square value. Thus, a mutual correlation coefficient can be equivalently calculated by simple circuitry.

Filed: 1979-12-07
Abstract: PURPOSE:To make connection highly efficient and changing-over operation easy by revolving the other connector of the optical transmission bodies which are butt- connected within an adapter around the central axis of one connector. CONSTITUTION:The state in which the end faces of plugs 4, 5 are superposed with each other and the connected state of optical transmission bodies are illustrated and the mutually connected optical transmission bodies are shown by black spots. If an adapter 1 is rotated left around the central axis of the plug 4 from the state that the optical tansmission body 31 is held connected to the optical transmission boy 11, the plug 5 revolves in a left direction around the central axis of the plug 4; therefore, the optical transmission body 31 is changed-over from the optical transmission body 11 to the optcial transmission body 12. Further as similarly, the optical transmission body 31 is changed over to the optical transmission bodies 12, 13 requentially. At this time, the plugs 4, 5 assume rotating contrapositions with respect to the adapter 1; therefore, the plug 4 stops and the plug 5 makes revolution only, without rotation of both, hence the optical transmission bodies 11, 12-31 do not twist.
