Patent JP-S6061039-A (JP)
Title: Ion exchanging method
Inventor: KOSUGE MASAO
IPC: G03C5/395
Filed: 1983-09-13
Abstract: PURPOSE:To recover and reutilize efficiently an expensive high-concn. aq. soln. of halogenated alkaline salt simultaneously with the recovery of silver by bringing the high-concn. aq. soln. of the halogenated alkaline salt contg. silver into contact with a basic ion-exchange resin. CONSTITUTION:The high-concn. aq. soln. of a halogenated alkaline salt (e.g. an aq. soln. of potassium iodide) contg. silver is brought into contact with a basic ion-exchange resin, and a silver complex is adsorbed when silver is removed from the aq. soln. Although a batch method can be used for the treatment, a circulating treatment by using a fixed-bed ion-exchange tower is suitable. Since the ion-exchange adsorption rate of the silver complex under said conditions is slow, the treatment is usually carried out preferably at 1-10/hr space velocity and 40-60 deg.C. The expensive high-concn. soln. of the halogenated alkaline salt can be efficiently recovered and reutilized simultaneously with the recovery of silver in this way.

IPC: G02B7/28
Filed: 1981-10-22
Abstract: PURPOSE:To detect a track shift stably, by making a part of a reflected ray from an optical disk incident onto a photodetector through a convex cylindrical lens. CONSTITUTION:A part of a reflected ray from an optical disk 4 is made incident to a photodetector 26 through a convex cylindrical lens 23. Light 11b used for detecting a track shift is in a state that light of a position deflected in the lengthwise direction of a tracking guide against an optical axis of an objective lens 17 has been extracted. As for an image formation pattern of the tracking guide reflected in an elliptical bean spot 11b' on the photodetector 26, the  lengthwise direction of a shadow 30 of a diffracted pattern is a direction indicate with an arrow A. When an optical head 3 moves in the direction crossing the tracking guide, the shadow 30 moves in the direction as indicated with an arrow B, therefore, a difference between a photodetector 26c and 26d, or 26e and 26f becomes a track shift signal.

In this case, the polymer precursor 11 is properly weighed and sampled to a light-transmitting vial 10 or the like which is irradiate with UV rays as a first polymn. process. Then, a liquid crystal material is added to the polymer precursor. Then, an insulating film is placed as a spacer 15 on one substrate 13 of the substrates on which the sample after the mixing of the liquid crystal material and the polymer precursor partially polymerized in the first polymn. process is completed is applied.  Successively, when the sample is irradiated with UV rays as a second polymn. process, the polymer precursor is polymerized to be hardened. At the same time, the liquid crystal causes phase separation from the polymer to form the liquid crystal drops.

IPC: H04B10/07
Filed: 1979-12-27
Abstract: PURPOSE:To detect abnormality of the photoelectric transducer by synthesizing a transmitting photosignal and a monitoring photosignal which are different in frequency from each other, by inputting the same in the photoelectric transducer and by detecting a corresponding electric signal from the transduced signal. CONSTITUTION:The photosignal from a transmission signal line 1 and the monitoring photosignal 2 having different frequencies from each other are synthesized 3 and transduced 4 photoelectrically. The output thus obtained is separated by filters 5 and 7 into a transmitting electric signal and a monitoring electric signal. The level of the monitoring electric signal is compared 8 with that of a reference electric signal 9 and, when the former is smaller than the latter, the photoelectric transducer 4 is determined to have some abnormality. On the occasion, the monitoring photosignal has a frequency without the frequency band of the transmitting photosignal. By this constitution, the smooth transmission of the signal, as well as the presence of the abnormality in the photoelectric transducer, can be detected and thus the device is effective for practical use.

Abstract: PROBLEM TO BE SOLVED: To realize a high freshness control of products and an energy saving by totally and rationally controlling a showcase and a refrigerator. SOLUTION: A general, controller 21 is disposed between a group of showcases 1 and a refrigerator 6 and comprises a solenoid valve operation arithmetic part 3, an estimation part 4 and a rotational speed command part 5. The solenoid valve operation arithmetic part 3 obtains a current average solenoid operation rate, namely, an ON time rate of respective solenoid valves during 30 minutes from the past to the present in response to solenoid operation signals from respective controllers 34A, 34B, 34C. The estimation part 4 estimates a balance condition of the capacity of a refrigerator against a showcase load.

Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To save troubles for acquiring a precise code a for a new base station in a mobile unit by simultaneously broadcasting (intermittent)code identification data which are not diffused. SOLUTION: Information on a PN sequence is transmitted through a perch channel in a CDMA system. For improving acquisition time, a marker formed of a short gold code SCo is transmitted periodically. To have synchronization realized a mobile body decides the position of SCo and detects which SCN is received at present from SC1. Thus, a long code group is decided. For relieving long search for deciding the precise long code during use, the block code of length (n) is used for alphabets constituted of q-pieces of marks as a group code. This corresponds to the transmission of the sequence of marks C1, C2,..., Cn.

Title: Vibration proofing method and device thereof
Inventor: UCHINO KENJI
IPC: G05D19/02
Filed: 1988-07-08
Abstract: PURPOSE:To obtain an excellent vibration-proofing effect in a short time, by converting vibration of an object for vibration-proofing into an electric signal to be detected, and providing inverse vibration to the object for vibration- proofing by means of a vibrator, the inverse vibration which is oriented inversely of vibration of the object, and the magnitude of which is determined in accordance with that of vibration thereof. CONSTITUTION:When external force is exerted on an object 3 for vibration- proofing and vibration is generated therein, the vibration is transmitted to a piezoelectric element 2, so that the piezoelectric element 2 stretches or shrinks in accordance with the vibration, to thereby output voltage signals to a detector 5. The detector 5 outputs the signals thus detected to a controller 7, which outputs voltage being inverse of the output voltage of the piezoelectric element 2 of its sign and having its magnitude determined in accordance with that of the output voltage to the piezoelectric element 2. Vibration of the piezoelectric element 2 is thus rapidly attenuated and vibration of the object 3 for vibration-proofing is also rapidly attenuated. Thus the controller 7 controls vibration positively in accordance with the quality of vibration, so that vibration which is temporally variable can be controlled in a shorter time.
