Abstract: PURPOSE:To apply the large pressure change caused by the intermittent collision of a fluid with an object to be massaged by providing a perforated planar body supporting a membrane approaching a nozzle and keeping the min. spaced- apart distance of the membrane to the nozzle constant. CONSTITUTION:A pump 2 and the nozzles 3 injecting the fluid sent form the pump 2 under pressure to the air above a liquid tank 1 are received in the liquid tank 1. The metal net 4 permitting the fluid injected from the nozzles 3 to pass is provided to the upper part of the liquid tank 1 and the upper part of the liquid tank 1 at a definite distance from the metal net 4 is covered with a membrane 5 made of a soft resin to be hermetically closed. The metal net 4 has strength not approaching the jet orifices of the nozzles 3 over a definite distance or more even when the load due to a foot 6 acts on the metal net 4. Therefore, the injected fluid is dispersed to collide with the membrane 5 in a state ready to become water particles and the foot 6 placed on the membrane 5 receives the intermittent fluid and, therefore, the change of the pressure due to the fluid received by the foot 6 is large.

Title: Pulse string output circuit
Inventor: OHARA KOICHI
IPC: H03K3/78
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To constantly output a pulse string even if an idle area exists in plural storage areas by permitting a data read selector to sequentially switch only pattern data storage buffers independent of a write selector. SOLUTION: Output pattern data Dp is continuously stored in any ring buffers 1 connected to the data write selector 2 with a write command signal WR as a trigger. At that time, the data write selector 2 is switched by a write data switch command Se1 from a ring buffer control circuit 4 and the buffers are selected and sequentially stored. The data read selector 3 sequentially switches the buffers 1 from the buffer where pattern data Dp is stored independent of the data write selector 2. Since only the buffer where pattern data is stored is selected even if the idle area exists in the plural storage areas, the pulse string of the pattern can continuously be outputted.

Title: Optical receiver and optical add/drop device
Inventor: OTANI TOMOHIRO
IPC: H04B10/2507
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To eliminate the necessity of a dispersion compensation fiber for a receiving terminal station. SOLUTION: Signal light (wavelength λs) inputted from an optical transmission line to an input terminal 10 is made incident upon a multiplexer 14 through an optical amplifier 12. The multiplexer 14 multiplies output light from the amplifier 12 by probe light (wavelength λp) from a probe light source 16 and applies the multiplexed light to an EA modulator 18. The modulator 18 superposes the waveform of the signal light of the wavelength λs on the probe light. An optical BPF 20 transmits only the component of probe wavelength λp out of output light from the modulator 18. A light receiving element 22 converts the output light of the BPF 20 into an electric signal and an amplifier 24 electrically amplifies the output of the element 22.  An BPF 26 extracts the clock component of input signal light from the output of the amplifier 24 and supplies the extracted component to a driving circuit 28. The circuit 28 pulse-drives the probe light source 16 at the same frequency as that of the clock signal outputted from the BPF 26 and adjusts the phase of the pulse so as to synchronize it with a current pulse generated from the modulator 18. A laser light source 16 generates a probe light pulse in accordance with a driving signal outputted from the circuit 28.
