Title: Organic solvent vapor adsorption apparatus
Inventor: TANIGUCHI TAKASHI
IPC: B01D53/81
Filed: 1993-09-08
Abstract: PURPOSE:To perform advanced purification with low heat consumption by installing a purge zone between a regeneration zone and a treating zone of an air current passage of a rotor and using air passed through the rotor as a part of regeneration heating air in the purge zone. CONSTITUTION:In an adsorption apparatus where air contg. organic solvent vapor A is continuously treated while a rotor 1 consisting of a honeycomb structural body on which an adsorbent is carried is rotated, an air current passage of the rotor 1 is divided into a treating zone 5, a regeneration zone 4 and a purge zone 7 by separators 6 installed near both the end surfaces of the rotor 1. Air P is fed to the purge zone 7 to cool the rotor 1. The air P passed through the purge zone 7 is used as regenerating heating air R through a heater H. Since after the rotor 1 is sufficiently cooled in the purge zone 7 in this way, it enters the treating zone 5, an adsorbent on the rotor 1 makes full use of its complete adsorption power from the beginning to prevent the leakage of the solvent vapor. And you can do without much heat consumption.

Filed: 1990-09-18
Abstract: PURPOSE:To collect data only by preparing one recording medium for each driver by using the prescribed areas of the storage medium for registering information concerning a card disabling a credit transaction and for storing time sequantial data. CONSTITUTION:A read / write means 13 reads out information, which is registered on the prescribed area of a storage medium 17 in advance, concerning the card disabling the credit transaction, the read information concerning the card disabling the credit transaction is stored in a storing means 13, and the time sequential data are written in the prescribed area of the recording medium 17 while being superimposed onto the information concerning the card disabling the credit transaction. Therefore, since the prescribed areas of the storage medium 17 are used for writing both data such as the information concerning the card disabling the credit transaction and the time sequential data, it is not necessary to use the two storage media 17 for storing the respective data. Thus, various data can be collected by one storage medium 17 for each driver.

Title: Optical voltmeter
Inventor: WATANABE IKUO
IPC: G02F1/03
Filed: 1988-09-30
Abstract: PURPOSE:To measure voltage without applying bias voltage by calculating voltage based on the actually measured natural double refractivity of an electro- optical element. CONSTITUTION:The laser beam from a light source 1 is polarized at a polarizing angle theta of -41 deg. in a Y-axis direction by a polarizer 13 and revolved around the beam axis of an electro-optical element 7 wherein no voltage is applied between electrodes 17 to be received by a photodetector 11 through a detector 23 wherein the deflection angle theta is freely selected. From the light detection outputs + or -1, + or -2 when the polarizing angle theta is 45 deg. and -45 deg., the natural double refractivity psi0 of the element 7 is determined without adding bias voltage to the element 7. Subsequently, the polarizing angle theta of the detector 23 is fixed to 45 deg. to apply voltage V to the element 7 and voltage V is calculated from light detection output I by the apparatus 26. By a method requiring no large bias voltage largely changing corresponding to the minute change of temp. or a light path length, photo-voltage is accurately measured.
