Title: Ion sensor
Inventor: NONOYAMA JOJI
IPC: G01N27/416
Filed: 1995-05-22
Abstract: PURPOSE: To obtain an ion sensor not generating the error caused by ions to be measured by detecting the voltage of the soln. to be measured received in the hole of a plate member by ion responsive and ion non-responsive electrodes. CONSTITUTION: When a liquid to be measured is dripped in the bottomed hole forming the through-hole 21 of a case 20 to the upper surface of a sensor unit 40, the ion responsive electrode 41 and ion non-responsive electrode 42 on the upper surface of the unit 40 are immersed in the liquid to be measured. Ions to be measured are bonded to the ion selective film 412 of the electrode 41 and the voltage induced in the selective film 412 is detected by a metal sintered film 411. At this time, a substance adsorbing ions to be measured is not bonded to the electrode 41 and, therefore, the measuring error caused by the ions to be measured is not generated. The selective film 422 of the electrode 42 adsorbs no ions to be measured and the sintered film 412 detects the voltage by the ion to be measured and does not detect the voltage by the ion to be measured.  The detection signals of the sintered films 411, 421 are amplified by field-effect transistors 43, 44 to be sent to a measuring electronic circuit.

IPC: F28D17/00
Filed: 1979-09-21
Abstract: PURPOSE: To cool down liquefied gas below standard boiling point using a simple construction through the process consisting of injecting noncondensing gas in the liquefied gas, letting the liquefied gas evaporate in the forth of the noncondensing gas taking out the both in mixture state and lowering the vapor pressure of the liquefied gas in a container.  
     CONSTITUTION: When noncondensing gas B is injected in the liquefied gas in a container, the liquefied gas evaporates in the froth of the noncondensing gas B so that the liquefied gas itself is cooled down while the evaporation latent heat taken away. The evaporation pressure of the liquefied gas A in the gas in the gas-phase part of the container lowers when the mixture C of the vapor of the liquefied gas A and noncondensing gas B is released outside the container through a discharge  port 4 and the liquefied gas is cooled down below standard boiling point depending  on the partial pressure thereof. Thereby, the liquefied gas can be cooled down using a simple construction and the desirable choice of generation temperature and cooling capacity is possible by selecting the combinations of the liquefied gas and noncondensing gas so that a wide scope of application becomes possible.

Title: High speed motor
Inventor: BAN ITSUKI
IPC: H02P6/06
Filed: 1991-03-07
Abstract: PURPOSE:To obtain a reluctance type motor and a brushless DC motor having a high speed, a large tprqie and an excellent efficiency. CONSTITUTION:When energization of one armature coil is stopped, magnetic energy stored in a core is prevented from being circulated to a power source side by a reverse preventing diode, fed to and charged in a capacitor having a small capacitance to be held at a high voltage, and hence a current is abruptly dropped. Next armature coil is energized after a predetermined time, but since a charge voltage of the capacitor becomes high by the applied voltage, and hence the current is abruptly raised. Since the rise and fall of the current of the4 armature coil become abrupt, a motot can be rotated at several tens of thousands rpm. Further, means for energizing an inductance coil at the time of energizing the armature coil supplying magnetic energizes of both in the capacitor when the energizations of both are interrupted, energizing an armature coil to be energized next and supplementing energy loss due to copper loss and iron loss, is employed. Accordingly, a reluctance type motor having a high speed and a high torque can be obtained.

Title: Combustion of town gas and apparatus therefor
Inventor: OKADA OSAMU
IPC: F23C99/00
Filed: 1989-05-17
Abstract: PURPOSE:To considerably reduce SOx contained in exhaust combustion gas by a method wherein town gas is burnt after desulfurized by applying copper type desulfurizing agent which is prepared by a coprecipitation process. CONSTITUTION:Town gas is desulfurized by a desulfurizer 1 where copper type desulfurizing agent prepared by a coprecipitation process is filled, and the sulfur content is reduced to less than 1ppb. The desulfurized town gas is burnt by a burner 2 with an adequate excess air ratio, and the high temperature exhaust gas is sent to a dryer 5 to dry food, dyed fabric, etc. With this apparatus, the SOx concentration can be considerably reduced to less than 0.1ppb, or less than 0.01ppb under a desirable condition, so as not to affect items to be dried. Therefore, as the heat of the exhaust gas is directly used for drying, a high thermal efficiency can be achieved. The copper type desulfurizing agent is not particularly specified as far as it is prepared by a coprecipitation process, however, copper-zinc type or copper-zinc-aluminum type desulfurizing agent is preferably applied, for example.

Filed: 1988-05-20
Abstract: PURPOSE:To lighten a workload on an operator and to heighten work efficiency by equipping the title device with a storing means to store image data according to the order of ordered characters and outputting character patterns and the image data stored in the storing means according to the order of the ordered characters. CONSTITUTION:After the character patterns converted by a converting means 8 and the image data read by a reading means 12 are ordered according to the order of the ordered characters and stored in a storing means 13, the ordered character patterns and image data are outputted. Consequently, the character pattern of a recognized character and the image data of another character which cannot be recognized are combined and outputted together. Thus, it becomes easier to read the character which cannot be recognized, and the workload on the operator can be lightened by judging whether it is necessary to re-input one character or not and omitting the re-inputting of the judged character when the character is unnecessary, and consequently, the working efficiency can be improved.

Abstract: PURPOSE:To reduce the working cost by coating the surface of the tip section of a circular saw blade brought into contact with a body to be cut with the hardest material and automatically recovering the cutting performance against the abrasion of the blade. CONSTITUTION:The surface of the tip section 6 of the addendum 5 of a circular saw blade is coated with the hardest material 7. Coating is selected among evaporation, deposition, percolation, plating methods, etc. The hardest material 7 can be selected among, e.g., titanium, ceramics, etc. When the tip section 6 is abraded, a curved section 8 protruded at the rear is brought into contact with a body to be cut 9. Since the curved section 6 is soft as compared with the tip section 6, the portion 10 is quickly abraded when pressed hard to the body to be cut 9. Accordingly, the tip section 6 is automatically formed into a sharp addendum again, and the cutting performance is recovered.
