Title: Production of ceramic compact
Inventor: TANIGUCHI YASUYUKI
IPC: C04B35/00
Filed: 1992-05-28
Abstract: PURPOSE:To produce a ceramic compact excellent in characteristics in the absence of a hole by dry pulverizing a mixture of a ceramic raw material with a cellulosic binder, then adding a plasticizer and a dispersing agent thereto, kneading the prepared mixture, forming and burning the resultant kneaded mixture. CONSTITUTION:A methyl cellulose binder is added to fine powder of lead zirconate titanate-based piezoelectric ceramic and the resultant mixture is finely pulverized in a dry pulverizer. Glycerol as a binder and pure water as a dispersing agent are added to the pulverized mixture and the obtained mixture is kneaded in a roll mill. The prepared kneaded mixture is further vacuum extruded and formed into the shape of a thin plate, then dried, subsequently heated, degreased, further placed in a burning furnace and burned at a high temperature. Thereby, the objective ceramic compact excellent in mechanical strength and electrical characteristics in the absence of a hole having >=30mum diameter is obtained.

Title: Elastic surface wave gyroscope
Inventor: YUKAWA KAZUHIKO
IPC: G01C19/56
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To achieve a high detection level of a Coriolis force. SOLUTION: IDTs(interdigital transducers) 23 and 24 for generating elastic surface waves and reflectors 25, 25'-27 and 27' are arrayed on the surface of a piezo-electric substrate 21 in one row sandwiching an IDT 22 for detecting a Coriolis force. High frequencies (f0 +Δf) and (f0 -Δf) are applied respectively to the IDTs 23 and 24 from a high frequency oscillator to generate two kinds of elastic surface waves. Both the elastic surface waves are reflected by the reflectors 25 and 25' and the reflectors 26 and 26' to make a standing wave and an interfering wave (f0 ) is generated between the IDTs 23 and 24. Under such a condition, when the piezo-electric substrate 21 makes a rotating motion, an elastic surface wave attributed to the Coriolis force with the phase thereof shifted is generated by 90 deg. by interaction with the interfering wave.  This elastic surface wave is reflected by reflectors 27 and 27' to make a standing wave. This standing wave is converted to an electrical signal by a piezo-electric effect and detected by the IDT 22.

Title: Hot water supplying apparatus
Inventor: IWAMURA KAZUYUKI
IPC: F24H1/24
Filed: 1988-06-03
Abstract: PURPOSE:To eliminate a crack even if it is used for a long period of time, and to improve burning efficiency by disposing a combustion cylinder in which the end of a gun type burner is opened, and providing a plurality of openings communicating with the interior of an inner body at the periphery of the lower section of the cylinder. CONSTITUTION:Even if a flame is injected from a gun type burner 4, it is not directly injected to an opposite inner body face, but it is once held and agitated in a combustion cylinder 7, its injecting speed is decelerated and dispersively injected from a plurality of openings 8 of the cylinder 7. Accordingly, since the flame from the burner 4 does not locally heat the part of the inner body 1 but uniformly heats it, thermal stress, distortion acting at a water boiler 3 are not locally generated, and the inner surface of the boiler 3 is not cracked. Since the interior of the cylinder 7 is held at a high temperature, oil droplets from the burner 4 are completely vaporized, thereby improving its burning efficiency as compared with a conventional one.

Title: Method and device for tabulating measurement data of multicore optical fiber, and recording medium where tabulation program is recorded
Inventor: UNNO KOJI
IPC: G01M11/02
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To provide a method and device for tabulating measurement data of multi- core optical fiber wherein, connection loss of all event points, etc., are tabulated even with an event point which is difficult to be discriminated and dispersion in distance between the same event points. SOLUTION: A measurement waveform data of an OTDR device is taken in (S1), and event information is obtained with a step comprising connection loss of threshold value or above as an event point (S2). At first the event information of a head core- wire is registered in a master file (S3) for obtaining zone distance between event points (S4), and an event point within a specified range from each event point is searched out of an objective core-wire, which is taken as the same event point (S5). If an event distance of the objective core-wire is smaller than the master file, tire event information of the master file is replaced with the event information of the objective core-wire (S6). All event information in the objective core-wire which is not the same event point is registered in the master file (S7).  The steps S4-S7 are performed with all core-wires (S8 and S9), and tabulation is performed of connection loss, etc., for an event point (S10).

Title: Buffer storage control system
Inventor: ABE SHIYUUICHI
IPC: G06F12/08
Filed: 1983-07-27
Abstract: PURPOSE:To realize the speeded-up pipeline processing of instructions which require by two memory operands by dividing a buffer storage device into a storage device dedicated to operands and a storage device used for fetching an operand and an instruction in common. CONSTITUTION:The buffer storage device consists of the 1st buffer storage device 10-1 dedicated to operands and the 2nd buffer storage device 10-2 for fetching an operand and an instruction in common, and the both storage devices are accessed independently of each other. The 2nd buffer storage device 10-2 is used normally for instruction fetch, but when an instruction requiring two memory operations at the same time is executed, the 2nd buffer storage device 10-2 is used for operand fetch as well as the 1st buffer storage device 10-1, and they are accessed at the same time to obtain the two memory operands at the same time. Thus, an operand and an instruction are fetched independently in parallel and the pipeline processing of the instruction which requires two memory operands is speeded up.

IPC: H01P1/30
Filed: 1987-05-30
Abstract: PURPOSE:To obtain a dielectric resonator device which facilitates the matching of a coupling coefficient, is good in a temperature characteristic and facilitates the manufacturing by providing a clearance for coupling adjusting between the outer circumferential edge of a plate and a case. CONSTITUTION:A clearance 20 for adjusting coupling is provided between the outer circumstantial edge of a plate 13 and a case 10. The clearance 20 is provided at the case 10 side with a comparatively weak electric field intensity, not provided in the vicinity of a dielectric resonator 11, and therefore, even when a small error is at the clearance 20, a coupling coefficient is hardly changed. Thus, it is not necessary to prepare the clearance 20 for the coupling adjusting with a high accuracy. Further, even when the size of the clearance 20 for the adjusting is changed a little, the coupling coefficient is hardly changed, and therefore, it is not necessary to consider the expansion based on the temperature change of the plate 13 and the case 10 and the limit of the material of the case 10 and the plate 13 is minimized.
