Title: Diffuser of multiple stage centrifugal hydraulic machine
Inventor: TANAKA TADAO
IPC: F04D29/44
Filed: 1988-06-24
Abstract: PURPOSE:To make manufacture of a guide blade and a diaphragm easy, by forming plural number of guide blades by means of bending a diaphragm which is formed in a plate-shape from a thin plate, from the outer circumference toward the next stage side plate. CONSTITUTION:A guide blade 17 is in a bending shape from the outer circumference 16 of a plate-shape diaphragm 13, and the diaphragm 13 and the guide blade 17 are formed in one body from a thin plate by plastic work. Further, the radius of the guide blade 17 gradually decreases toward rotating direction P of an impeller and forms a diffuser 19 in which the cross section of a flowing path toward a casing cylinder part 11 gradually increases. By connecting the diffuser 19 to a returning flowing path 15 at the end of this guide blade 17, speed head at the outlet of the impeller 2 is converted to pressure head efficiently.

IPC: H01L27/082
Filed: 1988-06-24
Abstract: PURPOSE:To decrease a parasitic effect current to reduce a consumption current and to contrive the improvement of accuracy of the operation of a circuit by a method wherein parts to be used as the bases of a lateral transistor, which is formed in an epitaxial layer on a substrate, and parts to be used as the bases of a parasitic transistor, which is generated between the lateral transistor and the substrate, are surrounded with high-impurity concentration layers. CONSTITUTION:n<+> coupling layers 51 to couple with an n<+> buried layer 2 are formed directly under n<+> base contact diffused layers 71 of a lateral P-N-P transistor using n-type epitaxial layers 4 isolated from each I<2>L part by p<+> isolation regions 3 as its base regions, in a process identical with that for n<+> color diffused layers 5 of the I<2>L part. After this, a p<+> emitter diffused layer 61, p<+> collector diffused layers 62 and the layers 71 are formed. Thereby, the layers 62 are formed into such a structure that they are surrounded with the n<+> base regions 51 and 71. In this structure, as base layers 4 of a parasitic P-N-P transistor, which is constituted of the layer 61, the layers 4 and a p-type layer (a substrate) 1 are surrounded with the layer 2 and the layers 51 and 71, current amplification factor hFE is reduced. As a result, a parasitic current IO is decreased to a base current IB.

Title: Cpu mounting substrate
Inventor: KIJIMA ATSUSHI
IPC: G01R31/28
Filed: 1986-07-02
Abstract: PURPOSE:To improve a contacting reliability by providing a buffer gate to open and close between a cpu and a signal bus and providing a connecting means to connect a tool for an external substrate test having the cpu equal to the cpu to a signal bus. CONSTITUTION:When a cpu mounting substrate 4 is tested by using a tool 7 for a substrate test, an IC plug 9 connected to the tool 7 for the substrate test is connected to an IC socket 2, a tool fitting substrate 1 for the substrate test is loaded on the cpu mounting substrate 4 by inserting a connector 3 to a connector 6. Consequently, by the control signal from a cpu separating control part 20 in the tool fitting substrate 1 for the substrate test, a buffer gate 30 is closed, input output signals 12 and 13 from the cpu are separated and a cpu 5 is separated from an internal signal bus 11. On the other hand, the input/ output signal from the cpu built in the tool 7 for the substrate test comes to be input/output signals 14 and 15 from the tool for the test and is delivered to the internal signal bus 11. Thus, the contacting reliability is improved.

Title: Extending system for kana-kanji
Inventor: AOKI KATSURO
IPC: G06F17/22
Filed: 1986-07-02
Abstract: PURPOSE:To register more word information in a fixed-size extension area by limiting information to be registered in the extension area to only headings and grammatical information. CONSTITUTION:When an operator inputs a heading, for example, 'kanji' with 4 key depression by a keyboard, this heading is transferred to a Kana (Japanese syllabary)-Kanji(Chinese character) conversion processing part 13. This Kana- Kanji conversion processing part 13 retrieves a fundamental constitution dictionary 11 with the number of key depressions as the key; and if the heading is found in a heading part 11a of the fundamental constitution dictionary 11, corresponding expression information and grammatical information are used to determine a candidate expression. The candidate expression is displayed on a display device thereafter. If heading 'kanji' inputted by key depression is not found in the heading part 11a of the fundamental constitution dictionary 11 and the operator newly registers it n an extension area 12, only the heading and grammatical information are written in the heading part 12a and a grammatical information part 12b of the extension area 12, and a corresponding Kanji expression is stored on a floppy disc device 15.

Filed: 1987-06-24
Abstract: PURPOSE:To prevent fault such as inter-phase short-circuiting in such as a regenerative bridge circuit, by blocking a drive signal upon drop of voltage in logical circuit. CONSTITUTION:A three-phase A.C. input is converted into D.C. through a shared circuit 3 of a diode for rectifying three-phase input and a power transistor in a regenerative bridge, then inverted through an inverter 4 and fed to a motor 5. The power transistor in the shared circuit 3 is driven through a drive circuit 2, and when voltage of a logic circuit in the drive circuit 2 drops, the logic is disturbed to cause layer short in the shared circuit 3. Upon detection of voltage drop of the logic circuit, a logic circuit voltage drop detecting circuit 1 blocks drive signal for the drive circuit 2 and prevents inter-phase short- circuiting.

Title: Preventing method for frost heave of peripheral ground of low temperature underground tank
Inventor: TAKANO MORIKUNI
IPC: E02D31/14
Filed: 1979-12-05
Abstract: PURPOSE: To prevent a peripheral ground from a frost heave and to improve the safety of a storage tank by a method wherein a salt concentration of the peripheral ground of a low temperature underground storage tank is raised.  
     CONSTITUTION: Many boring holes 6 are bored with an interval within a range wider that an expected freezing area A of a peripheral ground 2 including the ground under a bottom plate 1a of an underground storage tank 1 such as one for LNG. A salt B having a high ionization such as sodium chloride is filled into each of boring holes 6 to form a pile type salt pillar 7. The salt B in this salt pillar 7 melts into an underground water in the peripheral ground 2 and is permeated into the peripheral soil. Further, a salt containing water is absorbed to the freezing plane by means of a water suction operation near the frost line developing from the periphery of the storage tank 1. Further, a salt concentration of the overall freezing soil rises owing to the water movement in the freezing soil. With this, the salt concentration in the peripheral ground 2 is raised, thus, a freezing proceeding speed of soil is delayed. And further, deformation of the peripheral ground 2 is prevented.

Title: Method for simultaneously measuring ion concentration change in cell and membrane potential change
Inventor: KOYANO TAKESHI
IPC: G01N33/483
Filed: 1995-06-23
Abstract: PURPOSE: To simultaneously measure a change in ion concentration in a cell and a change in membrane potential by sequentially recording intensities of fluorescences from a living tissue every time a first and a second excitation lights are projected. CONSTITUTION: A living tissue 80 to be measured is placed on a sample stage 20f of a fluorescent microscope 20. An excitation light selection filter-switching means 30 selectively switches excitation lights from a light of a light source 50 which excite a first and a second fluorescent pigments responding to an ion concentration change in cells or a membrane potential change and sends the light to the tissue 80. A fluorescence selection filter-switching means 40 selectively switches fluorescences generated from the first and second fluorescent pigments taken by the tissue 80, and a photodiode 60 measures the fluorescence. A control means 70 controls rotary discs of the means 30, 40 to synchronize with each other with a predetermined speed and a predetermined relationship, and also records outputs of the diode 60 in time sequence.  At the measuring time, the control means 70 sequentially records intensities of fluorescences every time the first, second excitation light is projected and arranges the data of the intensities in time sequence. Accordingly, both the change in ion concentration and the change in membrane potential can be practically measured at the same time.
