Title: Immersion apparatus for porous material
Inventor: KURASAWA YUKO
IPC: G02B3/00
Filed: 1993-11-12
Abstract: PURPOSE:To safely and surely perform the immersion treatment of a porous material at a low cost without damaging the porous material. CONSTITUTION:A porous material 4 and a primary immersion solution 6 of an amount to immerse the whole porous material 4 are put into an outer vessel 5 and the porous material is immersed for an arbitrary period. The depth of the outer vessel 5 is larger than the height of the porous material 4. A liquid- discharging member 7 is inserted into the outer vessel 5. The primary immersion solution 6 is over-flowed through the gap between the liquid-discharging member 7 and the outer vessel 5. A secondary immersion solution 8 is poured into the vessel through a feeding port and, simultaneously with the pouring operation, the liquid discharging member 7 is pulled up from the immersion solution. The porous material 4 is immersed in the secondary immersion solution 8 without contacting with outer atmosphere by this process to complete the exchange of the solutions.

Abstract: PURPOSE:To shorten an input/output time by retrieving directly the pointer breakdown part of the data base at every parentage by a mini-data base from which only a bit of pointer information is extracted. CONSTITUTION:A pointer information extracting means 2 reads out successively all records in the data base 1 which has the broken pointer information and extracts only the pointer information for the designated parentage, which the record has, to a pointer information file 3.

IPC: H04Q9/00
Filed: 1994-12-13
Abstract: PURPOSE: To provide equipment which has no influence upon an analog signal even in the case of connection to a transmitter loop by performing the control to shorten a resistor a prescribed limit time after operation of a transmission line. CONSTITUTION: When a hand held terminal(HHT) is connected to a transmitter loop 52, charging of a capacitor 12 is started by the current branched from the loop 52. A resistor 14 is properly selected to limit this current to such degree that an influence of the peak value of the charging current upon the reception meter side can be ignored. When charging of the capacitor 12 advances, the potential on the side of a point A of the capacitor 12 rises, and a comparator is inverted to make a switch 15 conductive when this voltage gets higher than the voltage of a reference voltage circuit 17. When the HHT is detached from the loop 52, the electric charge in the capacitor 12 is discharged through a high resistance 19, and the potential at the point A gets lower than the voltage of the circuit 17 to open the switch 15.

Inventor: JIYON KUURUSON JIEEMUZU
IPC: H03D7/16
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To exclude or attenuate an image frequency without using a tracking filter by mixing a signal which is 90 deg. out of phase with the necessary channel carrier frequency with an input signal, and adding and filtering the respective signals after their phases are adjusted. SOLUTION: First and second mixers 18a and 18b mix 90 deg. out-of-phase oscillation output signals S4 and S5 of selected frequency from an oscillator 20 with a block input signal S1 respectively. The mixture output signals S6 and S7 are advanced in phase by 45 deg. and delayed by 45 deg. by a phase shifter 22 as a Hilbert filter and the signals which are 180 deg. out of phase with each other are processed by an adder 24, so that a carrier frequency corresponding to the oscillation output after the image frequency is excluded is selected and outputted from a filter 26 of necessary center frequency.  Two frequency components of the signals S6 and S7 are derived from an upper and a lower sideband wave, so a mixer which mixes the asynchronous oscillator signal with the block signal shifts the phase of the frequency component derived from the lower sideband wave by -90 deg. and shifts the frequency component derived from the upper sideband wave by +90 deg., so that two components S6 and S7 from a down converter can be discriminated.
