Title: Injection molded sintered body of metal powder and manufacture thereof
Inventor: SEYAMA YOSHIHIKO
IPC: B22F5/00
Filed: 1988-09-20
Abstract: PURPOSE:To obtain a sintered body having the desired surface smoothness with simple operation at low manufacturing cost by sintering metal powder layer having particle size smaller than metal powder for injection forming sintered body on the surface of the injection molded sintered body. CONSTITUTION:For example, the metal powder particles 1 having so large diameter of particles that handling, etc., is easy, is mixed with binder of polyethyrene, etc., which make liquid-state by heating, and the injection molding is executed to the mixed material to obtain an injection molded body 11. Successively, on the surface 12 needing the smoothness in the whole surface of the molded body 11, the surface layer 13 of the metal powder particle 6 having so small particle diameter that the desired smoothness is realized, is formed. This molded body 11 is charged into a furnace and heated and after degreasing by decomposing and vaporizing the binder, this is raised to high temp. and sintered to obtain the sintered body 14 providing the sintered surface layer 7 on the injection molded sintered base body 2. By this method, the process and molding are made easy by using the coarse particle powder and cost is reduced and the desired surface smoothness is obtd. by using the fine particle powder only on the surface.

IPC: G09B29/10
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To definitely guide in voice on an intersection to be turned even if there is an intersection which is not an object to be guided before a to-be- guided intersection. SOLUTION: Before a next guiding intersection, a speech start point is set between such intersections where a distance D between intersections is longer than a distance L required for voice generation, and at the speech start point, a voice guide indicating n-th intersection which is to be turned is generated. If there is no intersection where the distance D between intersections is longer than the distance L, a voice guide indicating to turn an intersection X-m ahead is generated.

Abstract: PURPOSE:To obtain a through hole forming method which can attain a stable step coverage when it is covered with an interconnection metal film by etching a specific phosphorus glass film of an upper layer with buffered fluoric acid, and etching a nitride film of lower layer by RIE to form a through hole. CONSTITUTION:The construction of an interlayer insulating film of multilayer interconnection is formed in a 4-layer structure of a nitride film 12 of fourth layer, a phosphorus glass film 13 of 4 mol-% of phosphorus concentration of third layer, a phosphorus glass film 14 of 7 mol-% of phosphorus concentration of second layer and a phosphorus glass film 15 of 12 mol-% of phosphorus concentration of first layer. When a through hole is formed in the interlayer insulating film, the phosphorus glass films 15-13 of the first to third layers are removed by etching with buffered fluoric acid, the nitride film of the fourth layer is removed by etching by reactive ion etching to form a through hole. Thus, the phosphorus glass films of the first to third layers can be etched without irregularity in the thickness (t) of the remaining films, and the through hole can be easily tapered.

Abstract: PROBLEM TO BE SOLVED: To shorten a voice message by deciding the kind of a terminal of an opposite station according to the incoming telephone number of the terminal of the opposite station and selecting and outputting a voice message according to the decided kind of the terminal of the opposite station. SOLUTION: A modem part 3 when receiving an incoming telephone number information signal extracts the telephone number of the terminal of the opposite station from the incoming telephone number information signal and informs a main control part 1 of it. The CPU 1 in the main control part 1 temporarily stores the telephone number of the terminal of the opposite station in a work memory 13, and compares it with telephone numbers stored previously in a backup memory 4 to check whether or not there is a match. The backup memory 4 stores telephone numbers of terminals of opposite stations, with which a facsimile communication was made so far, as a communication history. When there is a matching telephone number, the CPU 11 judges that the terminal of the opposite station is facsimile equipment and selects a voice message dedicated to facsimile from a voice IC 5.

Title: System for measuring concentration of electrolyte
Inventor: TAKIGUCHI TOSHIO
IPC: G01N1/10
Filed: 1986-10-08
Abstract: PURPOSE:To permit continuation of a measurement operation without degrading accuracy by detecting the volume of a liquid to be measured failing to attain a prescribed value and discharging a soln. for calibration into a reaction tube for the liquid to be measured at the time of sucking the liquid to be measured from a supply vessel. CONSTITUTION:A signal for the abnormality in the volume of suction is transmitted from a pressure sensor 23 to a CPU 14 when the volume of the sample liquid to be sucked from the supply vessel into a sample liquid discharging nozzle 6 does not attain the prescribed value in a suction position (b). The CPU 14 stops the movement of the nozzle 6 from the position (b) to a discharge position (c) and moves the reaction tube 3 for the sample liquid slightly to the position of a calibrating liquid discharging nozzle 5 by a conveyor belt 4, where the calibrating liquid of the nozzle 5 is discharged into the reaction tube 3 and the measurement operation is continued. The electromotive forces of the calibrating liquid in the reaction tube 2 for the calibrating liquid and the calibrating liquid in the reaction tube 3 are, consequently, measured continuously in a measuring part 8a of an ion electrode 8. However, a level difference does not exist intrinsically in the measured values between the two and, therefore, the measurement operation is continued without aversely affecting the measurement results of the ensuing other reaction tubes even if such measurement operation is intervened.
