Inventor: FUERII JIYAN JIYATSUKU
IPC: G01N19/02
Filed: 1990-02-02
Abstract: PURPOSE: To optimize the characteristics of boring fluid and prevent large-sizing of a ground device by contacting a movable piston and a filtering cake and measuring each of viscous torque, friction torque and drawing force in the axis direction. CONSTITUTION: A measuring chamber consists of a chassis 3 and a cylindrical casing 1 and has inside a movable piston 5. After filling the casing 1 with boring fluid, it is fixed on a bottom plate, the casing 1 is pressurized from gas inlet side and the fluid is filtered by the pressure difference between two sides of a filter element 15. Then the lower surface of the skirt 29 is contacted to a filter cake by the function of the piston 5. This contact between the lower surface and the filter cake is detected with a stress sensor 25. After elapsing a specific time, separation force, viscous torque value and friction torque value in the direction perpendicular to the contact surface of the skirt 29 on the filter cake are measured respectively.

Title: Automatic measurement for concentration of ammonia contained in gas mixture
Inventor: KEIL GARY D
IPC: G01N1/00
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To measure the content of ammonia in a gas mixture containing water soluble and water insoluble ammonia gases by applying the constitution that the ammonia gases contained in the gas mixture are dissolved in water and, then, a voltage signal corresponding to a pressure difference between the water and the gases is transmitted. SOLUTION: A water reservoir 30 receives water through a water filling solenoid valve 36, and supplies the water to a measurement vessel 20 via a feedwater pipe 33 while maintaining the prescribed water level. The measurement vessel 20 receives water via a water inlet solenoid valve 35 and a gas mixture from a gas introduction pipe 40 via an inlet solenoid valve 45 respectively by an amount enough to dissolve ammonia gas contained in the gas mixture. In addition, a differential pressure transducer 60 detects pressure due to water containing the dissolved ammonia at a high-pressure port. Also, the transducer 60 detects pressure due to the gas mixture at a low-pressure port. Furthermore, voltage signals are transmitted, depending on a differential pressure between the detected water and gas pressures. A recording means collects the voltage signals and converts the signals to ammonia concentration values.

Inventor: ENDOU MUNEHIRO
IPC: B22D11/06
Filed: 1982-02-19
Abstract: PURPOSE:To provide a corrector for ingot deformation for continuous casting installations which decreases or eliminates the sectional deformation already generated in a continuous casting ingot by detecting the form of the sectional deformation to be generated in said ingot and cooling the corner parts forcibly and locally in order to correct the sectional deformation positively. CONSTITUTION:An ingot 8 having a solidified shell 11 formed in a molding section and an unsolidified melt 12 therein is advanced on a guide table 9 located behind the casting section. If the ingot 8 in this case has already deformed to a corner B side and has less sharp angle on a corner A side, the ingot is treated in the following way: Cooling water is sprayed concentrically by a corner spray 15 to the part of the corner A to accelerate the growth of the solidified shell on the corner A side. The ingot 8 having a normal shape is thus obtained, and since the ingot can be corrected according to the degree of the deformation, the cracking of the solidified shell occuring from the inside part of the ingot is prevented and the ingot 8 having good quality is obtained.

Inventor: AOYAMA SHIYUNICHI
IPC: F01L13/00
Filed: 1983-02-16
Abstract: PURPOSE:To reduce cost in an arrangement where the valve operating characteristics can be switched by displacing rocker arms by a hydraulic actuator by actuating the hydraulic switch valve by utilizing an intake manifold pressure.

Abstract: PURPOSE:To eliminate the degradation of picture data by enabling the access of a data base by terminals whose resolutions are different. CONSTITUTION:When retrieval keywords are delivered to a control device 3 from terminals 6 to 9 in a retrieval processing, the data for which a retrieval request is performed is taken out from a host computer 1. As the data is coded, a control device 3 adds a parameter for conversion to it, a decoding is performed for it by being transmitted to a compression extension means 4 and it is returned to picture data. Next, the control device 3 adds a parameter for conversion for producing picture data conformed to, the resolution of a request origin terminal and transmits it a density conversion means 5. The density conversion means 5 compares the request origin terminal resolution existing within the parameter for conversion and the resolution at the time of preparing picture data, selects an optinum conversion ratio, performs the expansion or reduction of the picture data and returns it to the control device 3. When the control device 3 transmits the received picture data to the request origin terminal, the retrieval processings such as the display on the screen or the printing to a printer, etc., are terminated at the terminal.

IPC: G03G15/05
Filed: 1981-02-23
Abstract: PURPOSE:To reduce running torque with limited friction by coating a sponge- like plane fastened on a supporting member with a film-like member in a recording head holding mechanism for bringing a multi-stylus electrode assembly into contact with a recording body. CONSTITUTION:A multi-stylus electrode assembly 1 is arranged on a head holding mechanism in contact therewith through a recording body 7 to adjust the gap between a discharging pole 2 and a recording layer 8 to be a thickness defined by a paint 11. A signal voltage is applied between electrodes 2 and 3 to form an electrostatic latent image on the recording layer 8 which is transferred on to a plain paper by a xerography method. The gap between the electrode 2 and the recording layer 8 is kept even to the length of the multi-stylus electrode in the same degree as the thickness of a gap retaining paint thereby providing at latent image free of pits. In addition, a film 14 such as Mylar wrapped on a sponge 15 can reduce the friction between a base cell 10 and a head holding mechanism thereby preventing the infiltration of a toner and impurities into a sponge-like material, as generated during running.

Title: Temperature detection apparatus
Inventor: YAMASHITA HIDEKAZU
IPC: G01K7/24
Filed: 1985-02-13
Abstract: PURPOSE:To prevent erroneous operation at the time of low temp., by constituting the titled detection apparatus so that the high resistance state and disconnection state of a thermister at the time of low temp. can be discriminated. CONSTITUTION:Even if the resistance of a thermister 1 becomes high at low temp., voltage Vin detected by the voltage drop of a diode 3 in a positive direction generated by a slightly flowing current is not lowered and, therefore, does come to a disconnection detection region even if temp. reaches -20 deg.C. However, if thermister 1 is brought to a perfect disconnection state, no current is perfectly flowed and, therefore, the voltage drop of the diode 3 in the positive direction comes to zero and voltage Vin comes to zero. As a result, the detection of disconnection can be certainly detected.

Title: Ceramic honeycomb structure and its production
IPC: F01N3/28
Filed: 1989-02-06
Abstract: PURPOSE:To inexpensively and surely prevent the deviation of the through-hole direction of the honeycomb structure when used as a catalytic converter and to surely support the converter by corrugating only the periphery including the outer wall in the section vertical to the through-hole. CONSTITUTION:The outer wall 2 of the honeycomb structure 1 and the two cell walls 3-1 and 3-2 inside the outer wall constituting the honeycomb structure are corrugated in the through-hole direction. Since the periphery of the structure 1 is corrugated in the through-hole direction, the deviation of the through-hole direction is effectively prevented even when the catalytic converter using the structure is loosely supported in its radial direction. As a result, even if the structure 1 having a small partition wall thickness is used, a cushion material part pressed on the periphery in the through-hole direction in the conventional structure can be omitted, the converter volume is reduced, noble metals are efficiently used, the pressure drop is decreased, and the output of an engine is improved.
