Patent JP-H0396926-A (JP)
Title: Optical switch
Inventor: UEKI TAKESHI
IPC: G02B6/12
Filed: 1989-09-08
Abstract: PURPOSE:To suppress deterioration in extinction ratio by making the length from a physical branch point between branch-side optical waveguides to the downstream-end part of a control part as to the overall length of a refractive index control part larger than a specific value. CONSTITUTION:The light intensity of radiation-mode light increases as a branch angle theta increases. Further, the radiation-mode light which is propagated in an upper clad layer positioned between branch-side optical waveguides B1 and B2 is diverged as it is propagated, so its intensity decreases gradually. The light intensity of the radiation-mode light is therefore controlled according to the state how large the branch angle theta is and how long refractive index control parts C1 and C2 positioned on the downstream side of a physical branch point are. As for the overall length of the refractive index control parts, the length from the physical branch point between the branch-side optical waveguides to the downstream end part of the refractive index control part is >=100Xtheta/cos(theta/2)mum.

IPC: A61P25/28
Filed: 1990-09-03
Abstract: PURPOSE:To obtain a remedy for dementia effective against dementia, especially Alzheimer-type dementia and Alzheimer disease by using a chalybeate known as a remedy for sideropenic anemia in combination with coenzyme Q10 and vitamin B6. CONSTITUTION:The objective remedy for dementia contains vitamin B6, a chalybeate and coenzyme Q10 as active components. The addition of the chalybeate is effective not only to develop the dementia-amelioration effect in a short period but also to decrease the amounts of coenzyme Q10 and vitamin B6. The remedy for dementia may be a mixture of three components consisting of coenzyme Q10, vitamin B6 and the chalybeate, a mixture of two components consisting of coenzyme Q10 and vitamin B6 or coenzyme Q10 and the chalybeate, or a simple preparation containing coenzyme Q2. In the case of two-component preparation or a simple preparation, it is necessary to separately administer the other components. The remedy exhibits remarkable effect and has no side action.

Title: Reference clock switching type phase comparing circuit
Inventor: TAKEI KAZUHIRO
IPC: H03L7/08
Filed: 1993-09-20
Abstract: PURPOSE:To prevent a sudden variation of output pulse width caused by selection switching by outputting a phase difference of both clocks obtained by allowing each frequency of a selected reference clock and an output clock of a VCO to be subjected to (n) and (m) frequency divisions, as pulse width. CONSTITUTION:An inverter INV, AND circuits A1, A2 and an OR circuit OR switch a reference CK (RCK) 1 to an RCK 2 by a clock (CK) switching signal. F1 and F2 of FF circuits (F1-F4) allow each frequency of the RCK and the CK of the VCO to be subjected to two frequency divisions, respectively, as (n) and (m) frequency dividing circuits, and F3 further allows an output of F1 to be subjected to two frequency divisions. A phase comparator is constituted of F3, F4 and an exclusive OR circuit EX, an output 4 of F3 is latched by a VCOCK, and the circuit EX takes exclusive OR of the output 4 and an output 5 of F4, and outputs a signal PC of width for showing a phase difference. In such a way, even if a point in which width of the RCK becomes two folds is generated from the circuit OR, a pulse of narrow width is not generated, and a sudden variation of the signal PC can be prevented.

IPC: G01S15/18
Filed: 1991-08-20
Abstract: PURPOSE:To obtain an ultrasonic distance measuring apparatus using ultrasonic- wave pulses, which can correctly detect a body without erroneous detection even if noises are mixed. CONSTITUTION:In the ultrasonic distance measuring apparatus, ultrasonic pulses are transmitted, the reflected wave from a body is received and the distance to the body is obtained based on the time delay from the transmitted time. Thus, a series of the detecting processings for obtaining the distance by the wave transmission and reception are repeatedly performed. A changed-amount computing means 5 obtains the changed amount between the distance to the body obtained in the detection one-time before and the distance obtained at this time. A distance estimating means 6 estimates the distance to be obtained at the next detection based on the obtained changed amount. A detecting-gate setting means 7 sets a detecting gate based on the estimated value. A judgment outputting means 8 judges the correct value only for the signal within the preset detecting gate, obtains the distance and outputs the results. These means are provided.

Title: Developing device
Inventor: IWAI YASUYUKI
IPC: G03G15/08
Filed: 1983-12-12
Abstract: PURPOSE:To eliminate the leak of a developer from an insertion and extraction port even when a developer container is inserted and extracted frequently by providing a developer scraping member and a means which returns a scraped developer to a storage chamber on the internal wall surface of the developer container. CONSTITUTION:When the developer container 20 is inserted into the insertion and extraction port 15 of a developing device 2, a projection at the outer circumfrenece of an inner cylinder 22 is fitted in a guide groove, so slots 21c and 22d never engage each other to flow a developer out. When the insertion is completed, the inner cylinder 22 becomes rotatable, but the projection 21a of an outer cylinder 21 is specified in rotation with a specifying groove 12a, so slots 21c and 22a of the inner and outer cylinders are aligned to each other to flow the developer into a hopper 6 lengthwise uniformly, forming a uniform toner image. A sticking developer is scraped off with the scraping member 17 during the attachment and detachment of the container 20, so no toner leaks out of the insertion and extraction port 15. Therefore, even when the container is inserted and extracted repeatedly, no developer is accumulated, so neither deterioration in scraping ability nor outflow of the developer is caused.

Title: Apparatus and method for decomposing treatment of toxic substance in exhaust gas
Inventor: ICHIKI MASAYOSHI
IPC: B01D53/86
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To reduce a load on a reheater by enabling a decomposition treatment of an organic compound of dioxins or the like in an exhaust gas in a low temperature atmosphere by combining an apparatus which easily discharges a catalyst of which decomposing performance is degraded outside a packed column with an apparatus which regenerates the degraded catalyst. SOLUTION: Since the temperature of an exhaust gas at an inlet of a catalyst packed column 2 is about 170 deg.C, ammonium sulfate and ammonium hydrogensulfate are separated on the surface of the catalyst, and decomposing performance of an organic compound of dioxins or the like is lowered in a short time. Since the decomposing performance of the catalyst near the inlet of the exhaust gas of the catalyst packed column 2 is most lowered at that time, the catalyst in this part is periodically discharged outside the catalyst packed column. The discharged catalyst is sent to a catalyst regenerator 3, ammonia-gas-containing exhaust gas heated at about 350 deg.C is flowed to the catalyst regenerator 3 by a purging line 4, and the exhaust gas and the catalyst are brought into gas-solid contact. Thereby, ammonium sulfate and ammonium hydrogensulfate which are separated on the surface of the catalyst can be desorbed, and the catalyst can be regenerated.
