Title: Method for operating communication system, comunication system and secondary station for using for said system
Inventor: OWEN FRANK CHARLES GWYN
IPC: H04M1/72516
Filed: 1991-12-13
Abstract: PURPOSE: To reduce power consumed by a secondary station in the case where it is out of the effective area of a primary station in a cordless telephone system. CONSTITUTION: A communication system such as DECT is equipped with plural primary (or fixed) stations (PS) geometrically separated, and plural secondary (or portable) stations (SS) capable of wandering to the primary station.

Title: Fuel injection device
Inventor: YOSHIDA TAKEO
IPC: F02M51/04
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To suppress the vibration of an impulse extending element and precisely supply a desired fuel by performing a current-carrying control so as to extend and contract the impulse extending element at least once every combustion cycle, and reading the voltage waveform signal to be added to the impulse extending element to add a negative feedback. SOLUTION: When a driving voltage is applied to an impulse extending element 17 in the state where fuel is filled in a pressurization chamber 50, an impulse extending element body 17a is changed in shape to generate a high pressure wave in the pressurization chamber 50. An injection valve 25 is opened by this impulse high-pressure wave to inject a high-pressure fuel through an injection port 41. In this case, the current carrying is controlled so as to change the impulse extending element 17 from the extended state to the contracted state at least once every combustion cycle and then to change it from the contracted state to the extended state. The voltage waveform signal added to the impulse extending element 17 is read to add a negative feedback.  According to this, the vibration of the impulse extending element 17 is suppressed, and the pressure fluctuation of the fuel is suppressed so that the fuel can be precisely supplied.

Title: Screw type joint
Inventor: MARUYAMA TADAKATSU
IPC: F16L13/00
Filed: 1991-12-13
Abstract: PURPOSE:To provide a screw type joint excellent in execution with neither sealant used nor rotation made of a pipe or a joint using a long-handle tool. CONSTITUTION:The cylindrical section of a screw type joint is made of a shape memory alloy which is processed so as to be radially enlarged, and the kind of thread is limited to taper thread. A pipe is screwed in until it can hardly be manually rotated, let the joint itself be contracted only by heating its joint portion thereafter, so that the joint is surely fastened at its screw position. By this constitution, there is no fear of mixing sealant with fluid within a pipeline, and no fastening of the screw with force applied to a tool is required, so that plumbing can be facilitated in a narrow space or in a poor footing. A pipe joint made of a shape memory alloy is apt to be unreliable in fastening when the outer diameter of a pipe to be fastened is dispersed in dimension, however in the case of the aforesaid joint, its performance can be stabilized, because the outer diameter can be made uniform in a process when the pipe is threaded.

Title: Combustion device
Inventor: TAKESHITA NAOYUKI
IPC: F24H1/10
Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To enable an accurate detected value to be measured even if a sensing means such as a CO sensor is replaced by a method wherein at least one of a control means and a sensing means has discrimination data to be discriminated from the other and the other means is provided with a discriminating means for discriminating the discriminating data. SOLUTION: An output value of a CO sensor 40 when no combustion is carried out is applied as a zero point value and stored in a memory 83 of a main body substrate 80. Then, this zero point value is measured at a suitable time such as a turning-on of a power supply for a combustion device and after elapsing of a specified period of time upon completion of combustion. In the case that the measured value is different from the zero point value, a zero point correction is carried out. With such an arrangement as above, it is possible to attain an accurate CO concentration by calculating a difference between an output value from the CO sensor 40 during combustion and this corrected zero point value under a control of a CPU 82 at a main board 80. Accordingly, it is possible to accommodate for an aging variation of sensitivity at the CO sensor 40 and to attain an accurate CO concentration.
