Title: Detection of leak point in piping
Inventor: KAWASE AKIRA
IPC: G01M3/22
Filed: 1986-05-16
Abstract: PURPOSE:To calculate the distance up to a lead point, by blocking a gas leakage inspecting section to seal inert gas therein and sucking said gas from one end of said section to form an air layer to a leak place and again introducing the inert gas under pressure to detect the air layer at the other end of the inspecting section. CONSTITUTION:The valves A-G of a leakage detecting section 1 containing a leak print P are closed and a line 2 is connected to said section 1 by utilizing an adaptor 4 and a blocking valve 12 is opened. Next, the valve A is opened and air is sent into the section 1 by a pump 3 and the valve 12 is closed to hermetically seal the air. Then, initial pressure and falling pressure after a definite time are measured by a pressure gauge 15 and the leak quantity is calculated from the leak place P. Subsequently, inert gas 14 is sent into the section 1 from an inert gas injection line 13 to substitute air. Next, the inert gas is sucked from the line 2 by the pump 3 to form an air layer X. The line 13 is again connected and the air layer X is pushed out to the side of the line 2 by the pressure of the inert gas and the concn. of oxygen is detected by an O2 sensor 6. If oxygen is detected, the distance up to the leak place P is calculated from the quantity of the inert gas sucked heretofore through a flowmeter 5.

Title: Terminal equipment
Inventor: YAMANE MICHIHIRO
IPC: G10L13/10
Filed: 1997-05-01
Abstract: PROBLEM TO BE SOLVED: To provide a terminal equipment which can easily notify a receiver person of the arrival of a message in the character conversation communication. SOLUTION: A terminal equipment 1i contains a voice synthesizing program which converts the character strings into voices with correspondence secured between the characters and the phonemic pieces. Thus, the arrival of a message is notified to a chat user 3i by converting the character strings of the message into voices or converting a prescribed short sentence showing the arrival of the message into voices by synthesizing of voices at the arrival time of the message. Then a voice analysis program is added to analyze the voices of the opposite party of a chat and to extract the phonemic pieces. Thus, a message is received in voices of the opposite party or the coat and the reception of the message can be known. Otherwise, the phonemic pieces are acquired by analyzing previously the voices of an announcer, a character, etc., so that a message is received in the voices of the announcer, character, etc., and the reception of the message can be known.

IPC: G01F15/00
Filed: 1983-06-23
Abstract: PURPOSE:To measure the flow rate accurately after it changes by a method wherein with a memory section for the preceding measured value provided, pulses from a flow rate sensor are inputted and the results of a specified computation of the present measured value are compared with the absolute value of the difference between the preceding and present measured values to perform a computation. CONSTITUTION:A flow rate sensor 1 is provided in a gas supply line and a sensor 2 is made up of a membrane type gas meter 2 and a lead switch 3 as a magnetic field detector to transmit a flow rate pulse each time measuring a unit weighing volume. The flow rate pulse is inputted into an arithmetic processor 4 which computes the flow rate per unit time. The device 4 has a timer 5 and an arithmetic processing section 6 provided with a memory section 7 for memorizing the preceding measured value. The processing section 6 performs a specified computation of the present measured value and compares the results with the absolute value of the difference between the preceding measured value of the memory section 7 and the present measured value. When the results of the present computation are larger, it computes the flow rate per unit time from the present measured value or the present measured value and the measured value memorized in the memory section 7. Thus, the flow rate after it changes can be measured accurately.

Title: Apparatus for sampling serum from blood sample
Inventor: ANAMI TAKAYUKI
IPC: G01N1/00
Filed: 1991-04-19
Abstract: PURPOSE:To efficiently correct serum without detecting a boundary surface by a method wherein a serum suction nozzle and an air injection nozzle are thrust in a test tube in which a blood sample wherein serum and blood clot are separated is received and test tube is subsequently inverted to suck serum and air is injected in the test tube at the same time. CONSTITUTION:A silicone separating material 7 is added to the blood sample collected by a vacuum blood collecting tube 1 and the blood sample is subjected to centrifugal separation treatment to be successively separated into blood clot 6, the separating material 7 and serum 5 from the lower part of the blood collecting tube 1. Then, a block 8 is moved downwardly to thrust a serum suction nozzle 3 and an air injection nozzle 4 in a rubber plug 8. Next, the block 8 is revolved to invert the blood collecting tube 1 and the serum 5 in the blood collecting tube 1 is allowed to fall to collect a desired amount of serum 5 by the nozzle 3 and, at the same time, air is injected in the tube in an amount wherein air corresponding to negative pressure is added to a serum suction amount from the nozzle 4. By this method, without detecting a liquid level or the boundary surface of serum 5 and blood clot 6, only the serum 5 in the sample can be effectively collected.

Filed: 1980-08-19
Abstract: PURPOSE:To prevent either positive or negative ghost, by extending exposure width of a photoreceptor at preexposure to be operated before a charging step, and changing a light intensity in accordance with the memory characteristics of a photoreceptor. CONSTITUTION:Preexposure is conducted with a remaining charge erasion lamp 9 before charging the photoreceptor of a photosensitive drum 1 with a primary charger in order to remove an after image effect of the photoreceptor, and a few kinds of plates different from one another in light transmittance are provided as controlling plates 11 between the lamp 9 and the drum 1 to select them in accordance with the photoreceptor. A positive ghost tends to occur in strong preexposure, but it can be erased by weakening the light. Preexposure width of the photoreceptor is preferably made equal to the whole width of a predestaticizer 10 or the width A+B, thus permitting an image freed of a ghost and a fringe effect to be obtaned by extending an exposing time even when the light is weak.
