Title: Production of quinoveone
Inventor: KUSAKA KAZUHITO
IPC: C07C41/30
Filed: 1992-12-28
Abstract: PURPOSE:To easily obtain quinoveone usable for dyeing, coloring and various other uses simply by heating a solution of sinapic acid known as a general intermediate metabolite of lignin of plant. CONSTITUTION:Sinapic acid is dissolved in a small amount of methanol, etc., distilled water is added to the solution and the mixture is heated at about 120 deg.C to obtain quinoveone. Crude quinoveone can be purified by adsorbing to cellulose, dissolving in a proper solvent and removing the solvent from the solution. The use of sinapic acid as a starting raw material is new. There are two types in quinoveone, i.e., reduced type quinoveone of formula I and oxidized type quinoveone of formula II. The oxidized type quinoveone exhibits noble color and has high stability. Quinoveone is a compound having strong bonding force to polysaccharides (e.g. cellulose) and proteins.

Title: Heterojunction bipolar transistor and its manufacture
Inventor: TAKAHASHI SUNAO
IPC: H01L29/73
Filed: 1998-12-09
Abstract: PROBLEM TO BE SOLVED: To improve high-frequency characteristic of a heterojunction bipolar transistor by achieving both the high current amplification rate and low base resistance. SOLUTION: In a carbon-doped AlxGa1-xAs base layer 3 of a heterojunction bipolar transistor, the concentration of carbon-hydrogen bonds is at least 10% that of carbon. The carbon-hydrogen bonds form traps in the base layer 3. When electrons are injected from the emitter, they are captured by the traps in the base layer and thereby are stabilized. The traps which capture the electrons suppress the recombination current caused by traps characteristic of the material, realizing a high-current amplification rate. Moreover, by including a heat treatment process in the formation of an element, hydrogen is released and emitted from the carbon-hydrogen bonds in an outside base layer 6, which increases the density of carriers in the outside base layer 6 and thereby realizes a low base resistance.

Inventor: NAKAMOTO HIROYUKI
IPC: G01N15/10
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To inform of the decrease of analysis precision of data, by detecting the degree of overlapping of distributions of a scattergram. SOLUTION: A syringe 4 pushes out specimen liquid between valves 1 and 2, to a specimen nozzle 6, with a constant flow rate, so that the specimen liquid is spouted to a first cell 7a. By opening a valve 8 at the same time, sheath liquid is supplied to the cell 7a. The specimen liquid is thus enclosed by the sheath liquid, and further squeezed thinnly by an orifice 11, and a sheathed flow is formed. Particles which are previously contained in the specimen can be made to flow one by one forming a line through the orifice 11. From an DC constant current power supply 15, a DC voltage determined by the electric resistance between electrodes 12 and 13 and a current value is generated. When particles pass the orifice 11, the electric resistance between both ends of the orifice 11 changes in proportion to the dimensions of the particles.  The change amount is amplified by an amplifier 16, and outputted as a resistance signal 29.

IPC: H01F7/18
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To provide a solenoid valve drive device for an injector which is able to stabilize fuel injection characteristic. SOLUTION: When a transistor 3 is switchingly operated, a counter electromotive force generated in a troidal coil 2 causes a capacitor 5 to be charged. Then a separation circuit 6 is conducted to cause a discharge current of the capacitor 5 to be supplied to a solenoid valve EB for an injector. Thereafter, at a time point at which a voltage at a node A is lower than a set value (when a current I flowing through the solenoid valve EB exceeds a peak value), the separation circuit 6 is put in its non-conducting state, so that the solenoid valve EB is isolated from the node A to thus block the passage of a current flowing from a battery BATT via the troidal coil 2 to the valve EB. A constant value of the current I is supplied from the battery BATT via a constant current circuit 7 to the injector valve EB.  As a result, a stable peak current is provided, be supplied from the capacitor 5 to the valve EB and the holding current following the peak current can be supplied to the valve EB.

Inventor: TANI JUNJI
IPC: C22C49/00
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To prevent the fracture of a composite material such as cracks from propagation through raising the rigidity of the composite material proper when unexpected external force is applied to the material. SOLUTION: This composite material is so designed that the matrix is incorporated with shape memory alloy wires or fibers in such a state that both ends thereof to be connected to a heating source are exposed onto the surface of the composite material. Vibration or impact applied to the composite material is detected by an acoustic elastic wave sensor or a piezoelectric sensor of thin film shape, transduced into control signals by a computing element; and based on the control signals, the heating source to be fed to the shape memory alloy wires is controlled. The heated shape memory alloy wires then develop crystal phase transformation therein, effecting rise in both compressive force and rigidity of the wires, and leading to the mechanical strength of this composite material.

Title: Anchor
Inventor: YAMADA AKIYO
IPC: E02D5/80
Filed: 1991-12-14
Abstract: PURPOSE:To prevent a tensile member from rusting and faulty anchoring, by removing bleeding water generated in the inside of anchor. CONSTITUTION:A anchoring sheath 5 with a specified length is superimposed on a sheath 4 with an arbitrary length. A favorable size of this superimposed length L is 150-1000mm. A clearance 6 through which a curing agent can pass is formed between the superimposed anchoring sheath 5 and sheath 4 having an arbitrary length. A favorable gap W of the clearance 6 is 1-5mm. When a curing agent 12 is injected, bleeding water 13 is brought in the anchoring sheath 5, but the water is absorbed in the curing agent 12 and discharged from the clearance 6 to the outside of the anchoring sheath 5. Even if percolated water from the ground reaches the sheath through cracks, the curing agent at the position where the anchoring sheath 5 and the sheath 4 with an arbitrarty length are superimposed with each other prevent further permeation of water.
