Title: Fiber for optical amplifier
Inventor: OISHI YASUTAKE
IPC: G02F1/355
Filed: 1993-06-28
Abstract: PURPOSE:To enhance the saturated output intensity without sacrifice of pumping efficiency by adding an active element of same kind as for the core glass to the clad glass of a fiber for optical amplifier having a core added entirely or partially with a 4-level based active element. CONSTITUTION:A signal light from a signal light source 11 is coupled through an optical coupler 13 with a pumping light from a pumping light source 12 and transmitted through an optical fiber amplifier 14, a silicon fiber 17, and an optical isolator 15 to a spectrum analyzer 16. The optical fiber amplifier 14 employes a silicon fiber having core and clad added with Nd<3+> in addition to a rare earth element, e.g. Ce, Pr, as an active element. The concentration of rare earth element added to the core and clad may be lowered gradually toward the radial outside. In this case, the signal leaking to the clad can also contribute to amplification and thereby the saturated output intensity can be enhanced.

The active matrix LCD 15 is supplied with a video signal through the switching elements, and the switching elements of the respective picture elements are driven by drivers such as a gate driver. When the still picture reproduced, a control circuit 20 controls, for example, a 2nd driver to stop generating scanning pulses for several seconds. Consequently, the active matrix LCD holds the signals of the respective picture elements as they are and can reproduce the still picture without using any frame memory.

Title: Capacity controller
Inventor: AKASHI YOICHI
IPC: H03H5/02
Filed: 1990-06-15
Abstract: PURPOSE:To enable integration and further to continuously adjust a capacity value by providing first and second capacitors for which one end is respectively commonly connected, connecting the other end of the first capacitor to a reference point and connecting the other end of the other capacitor through a variable resisting means to the reference point. CONSTITUTION:When the output of a D/A converter 3 is less than a threshold value voltage VT of an N-channel MOS transistor N1, the N1 is in a high impedance state and accordingly, the synthetic capacity observed from an input terminal 1 is C1+alpha(alpha<<C2). When the output of the D/A converter 3 is a peak potential, the N-channel MOS transistor N1 is turned to a low impedance and accordingly, the synthetic capacity observed from the input terminal 1 is almost C1+C2. When the output of the D/A converter 3 is an intermediate level, the resistance value of a capacity varying circuit 5 is determined by internal resistance when the N1 is conducted, and the synthetic resistance of resistors R1 and R2. Thus, the resistance value can obtain an arbitrary value from more than a number +KOMEGA as the value of the R1 to less than a number KOMEGA as the value of the R2.

Filed: 1982-09-09
Abstract: PURPOSE:To restrain the centrifugal force lower and increase the strength allowance by a method wherein space rings divided in plural number and structured in reduced thickness are arranged in ring shape, further said rings are assembled with supporting rings divided in plural number. CONSTITUTION:A spacer ring 6 is formed in half-circle dividing shape, assembled with supporting a ring 7 pinching a shaft 3 from both sides. When an axis of half-circle dividing direction of the spacer ring 6 is horizontal, an axis of half-circle dividing direction of the supporting ring 7 is decided in vertical. The space between a pair of flanges 8a, 8b of the spacer ring 6 is connected with a stay, as it is called, structured in reduced thickness.

Title: Image communication system
Inventor: HASEBE TAKASHI
IPC: H04N1/46
Filed: 1989-06-20
Abstract: PURPOSE:To reduce transmission lines by converting many-valued image informa tion into binary signals temporarily and sending them, and supplying the binary signals to a half-tone image estimating means and restoring them to the original many-valued image information (half-tone image) in a reception system. CONSTITUTION:The transmission system 10T reads and separates the many- valued image information into plural component color signals R, G, and B, which are converted into binary signals and then sent through a transmitting means 50. The sent signals are the binary signals, so three transmission lines are used for the transmission. The reception system 10R supplies the received binary signals to the half-tone image estimating means 90 to estimate the half- tone level of an aimed picture element, the binary signals are restored to half- tone signals having half-tone levels, and those half-tone signals are recorded by a recording means 100. Consequently, the many-valued image information can be obtained by the restoration even when the transmission lines which are used exclusively are reduced.

Title: Method of controlling operation of eight-valve type backwash system for condenser used in thermoelectric or nuclear power plant
Inventor: TAKAHASHI MASAHARU
IPC: F01K9/00
Filed: 1978-12-22
Abstract: PURPOSE: To reduce time required for backwash to a great extent and to protect cooling pipes against erosion, by preventing that the speed of cooling water flowing into cooling pipes of condenser exceeds a predetermined value while operating valves for effecting switching from normal wash to backwash or vice versa.  
     CONSTITUTION: In condenser 12, steam discharged from turbine 14 is cooled and condensed by cooling water such as sea water pumped up from intake port 10 by means of water circulating pump 9. Here, if cooling water is made to flow in condenser 12 in a fixed direction, for instance, in the direction of arrow 17, there is fear of cooling pipes 15 being closed at its inlet by foreign matters 16. Therefore, it is necessary to periodically change flowing direction of sea water flowing in cooling pipes 15. In changing the flowing direction of cooling water, closing of normal- wash outlet valve 7 of, for instance, condenser A is at first started and closing of inlet valve 3 is then started before said outlet valve 7 is completely closed. Subsequently, opening of backwash inlet valve 6 is started before valve 3 is completely closed, and then opening of outlet valve 1 is started for carrying out backwash before inlet valve 6 is completely closed.

Title: Mounting head of electronic component mounting machine
Inventor: SUEKI MAKOTO
IPC: H01L21/677
Filed: 1993-06-29
Abstract: PURPOSE:To mount electronic components which are easily affected by impacts by forming a communicating hole communicated with the outside air on the side section of a hollow shaft body to which a vacuum pressure is applied. CONSTITUTION:When a vacuum generating device is driven, the through hole 12 of a hollow shaft body is evacuated and electronic components are attracted by suction to the front end of a nozzle section 13. When the electronic components are attracted, the degree of vacuum in the hollow shaft body drops from the generated one, since a little amount of air gets into hole 12 from the communicating hole 31 of the hollow shaft body. In other words, the suction force of the nozzle section 13 becomes weaker. Therefore, the impact force can be weakened at the time of mounting the electronic components on a substrate and electronic components which are easily affected by impacts can be mounted on the substrate.
