Title: Surface treatment method for carbon fiber for reinforcement disposed into hydraulic matrix
Inventor: UEDA KOICHIRO
IPC: D06M15/55
Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To provide a surface treatment method, in which the adhesion of carbon fibers and a cured matrix is increased and carbon fibers can be used as the substitute of reinforcing bars in concrete. SOLUTION: Carbon fibers are impregnated beforehand with adhesives such as a liquid resin, a hydraulic substance such as non-hydrated cement, gypsum or the like is attached onto the surfaces of carbon fibers and adhesives are cured before disposal into a hydraulic matrix not solidified. A sheet shape, a stringy shape or the like is utilized as carbon fibers 2 for reinforcement, and the liquid resin is used as adhesives 3. When the hydraulic substance not hydrated adhering on the surfaces of carbon fibers reacts with excess moisture generated from a matrix section and is cured, adhesion among the matrix section and carbon fibers is increased because an anchoring effect is generated between the matrix section and the hydraulic substance.

Title: Lase-beam abrasion device
Inventor: YOSHIDA ZENICHI
IPC: C23C14/28
Filed: 1990-11-20
Abstract: PURPOSE:To stably form a film in a high vacuum by shaping a laser beam into sheet and forming a gas curtain between a laser beam inlet window and a target. CONSTITUTION:A laser beam 12 oscillated from an excimer laser 11, for example, is passed through a vacuum-sealed window 13 and injected into a vacuum vessel 14 to irradiate a target 16, and a film is formed on a substrate 22.

Title: Fuel-burning equipment
Inventor: KAWAKAMI AKIO
IPC: F23N5/00
Filed: 1988-12-14
Abstract: PURPOSE:To improve ignition performance and reduce the number of ignition by making a rotary speed of a burner blower slower than that available during ordinary combustion. CONSTITUTION:When the presence of flowing water in a water supply pipe 17 is detected by a flowing water switch 18, the first thing to do is to operate a burner blower 6, then prepurge a burner 4. After that operation is over, a block solenoid valve 10 and a solenoid valve 13 are opened while an ignition device 36 is also operated. A pressure proportional control valve 14 is controlled so that its valve opening may be proper to ignition. In addition, a rotary speed of the burner 6 is controlled so that its rotary speed may be lower than that proper to a gas supply quantity. In this manner, a flames can be prevented from being blown out during ignition by minimizing a ventilation quantity by the burner blower 6. Since enough air is available around the burner 4 during ignition, there is no trouble that affects ignition. Furthermore, the combustion volume during ignition is smaller than the maximum combustion volume which results in a reduced ignition noise.

Title: Surface acoustic wave element
Inventor: KOMINE KENJI
IPC: H03H9/25
Filed: 1994-12-21
Abstract: PURPOSE: To enhance frequency stability with respect to a temperature change by facilitating the change of the peak temperature of the element. CONSTITUTION: In the surface acoustic wave element in which an electrode is formed on a surface of a piezoelectric substrate whose temperature - frequency characteristic is a quadratic curve, fluoride polyimide resin is applied to the surface of the surface acoustic wave element and the thermal expansion rate of the resin is used to match the peak in the temperature - frequency characteristic of the element with an ambient temperature of the element. Thus, the temperature - frequency characteristic of the resin is added to the temperature - frequency characteristic of the substrate to shift the peak TP1 of the temperature frequency characteristic of the element before coating to an optional peak TP2 after coating.  Furthermore, resin causing a negative thermal expansion coefficient is applied to the element using the substrate having a linear temperature - frequency characteristic to decrease gradation of the temperature characteristic thereby enhancing the stability of the frequency.

Abstract: PURPOSE:To automatically adjust a sample timing so that the sampling of transmitted data outputted from a terminating device can be always performed at a stable value, regardless of the kind of the connected terminating device, or the kind or length of a cable connecting the terminating device. CONSTITUTION:A terminating device 2 outputs transmitted data SD1 to a data sample part 11 of a network terminating device 1 based on a transmitted clock ST2. A shift register 18 and a reset signal generating part 19 detect the changing point of the above mentioned transmitted data SD1, and resets a clock counter part 16 at the detecting point of time. The clock counter part 16 and an encoder 20 detect a part from the changing point of the transmitted data SD1 to the middle of the changing point, and outputs a sample signal 100 to the data sample part 11 at the detecting point of time. Thus, the data sample part 11 always samples the value of the part from the changing point of the above mentioned transmitted data SD1 to the middle of the changing point.

Filed: 1992-11-30
Abstract: PURPOSE:To draw out electrons and positive holes stored in a gate insulating film to an electrode side or a substrate side, suppress the deterioration of the gate insulating film caused by a re-writing operation and improve a re-writing strength by a method wherein writing or erasing pulses are time-divided and pulses whose polarities are opposite to each other are applied. CONSTITUTION:For instance, after pulses of -7V and +3.3V are applied t8 a control gate electrode 7 and a source 8 respectively for 1 microsecond while a drain 9 is opened and a substrate 1 is grounded, successively pulses of 6V and 0V are applied to the control gate electrode 7 and the source 8 respectively for 0.5 microsecond while the drain 9 is opened and the substrate 1 is grounded. After the above mentioned bidirectional stresses are applied for 10 cycles, an operation for confirming a threshold is performed. Thus letting one re-writing be composed of one writing, one erasing and the number of the re-writing operations are repeated. With this constitution, electrons and positive holes injected into an insulating film 6 are discharged, quantities of electrons and positive holes captured in the insulating film 6 are reduced and the characteristic fluctuation of the insulating film 6 is suppressed, so that the breakdown strength of the insulating film 6 can be improved.
