Title: Light-generating apparatus and liquid concentration-measuring apparatus
Inventor: SAITO MITSUHIRO
IPC: G01N21/41
Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To stabilize an emission amount quickly and stabilize concentration measurements, based on an index of refraction, by applying a periodically intermittent voltage to a light-emitting diode via a resistor and a capacitor connected in parallel at least to a part of the resistor. SOLUTION: A liquid concentration-measuring apparatus, based on an index of refraction, is provided with a light-emitting diode 20 to which a driving signal is fed from a light-emitting diode-driving part 100. The driving part 100 interrupts intermittently a source voltage VE with a constant cycle by turning on and off a switching transistor TR and feeds to the light-emitting diode through a parallel circuit of a resistor R3 and a capacitor C3. The intermittent driving voltage has a spike at a rise part because of a differentiation action of the capacitor C3. The light-emitting diode 20 is accelerated to heat itself by a driving current corresponding to the spike part, and therefore quickly stabilized when a main switch is turned on, etc.  When the resistor R3 is suitably divided and the capacitor C3 is connected in parallel to one side, the spike of the driving voltage can be set more suitably.

Title: Manufacture of optical part
Inventor: ROBAATO TOOMASU MAREE
IPC: C08F2/48
Filed: 1990-08-07
Abstract: PURPOSE: To make it possible to obtain optical parts of an integral type of less light loss by exposing the prescribed band of a layer of a radiation polymerizable compsn. to radiations, then heat treating the exposed band and further, polymerizing the compsn. CONSTITUTION: The layer 12 of the radiation polymerizable compsn. is formed and one or more of the prescribed bands 14 of the layer 12 are exposed to the radiations and are selectively polymerized and are further heat treated at the temp. induced by the polymn. On the other hand, the remaining bands 20 are held substantially without the induction of the polymn. by the heat treatment. The bands are then exposed to the radiations, by which the regions 20 enclosing he bands 14 previously exposed to the radiations are cured. Namely, the bands 14 previously exposed to the radiations are shrunk more than the regions 20 enclosing these bands by the heat treatment and consequently, the refractive index is made larger than in the ambient regions 20 and a gradient is generated to the extent of the polymn. between the bands 14 and the ambient regions 20.  As a result, the integral type optical parts less in loss of light are obtd.

Title: Low temperature operating solid electrolyte type fuel cell
Inventor: SHIMOZU MASATERU
IPC: H01M8/12
Filed: 1990-08-06
Abstract: PURPOSE:To reduce the starting time and the stopping time of a cell by reducing the resistance of an electrolyte and the electrode reaction to increase the reaction speed, and lowering the cell operative temperature. CONSTITUTION:As a solid electrolyte, a CeO2 system ceramics with a high oxygen ion conductivity is used, and by making the solid electrode in a thin membrane (less than 20mum), forming a film of a fuel electrode material on the surface of an inorganic porous base substance to increase the surface area of the fuel electrode so as to increase the contact surface with a fuel gas, and using a porous oxygen electrode to increase the contact surface with an oxidizer gas, the resistance of the solid electrolyte and the resistance of the electrode reactions can be reduced to prevent the reduction of the reaction speed. As a result, even when the cell is operated at a low temperature (less than 800 deg.C, for example), the energy efficiency and the output intensity same as or higher than the case on a high temperature operation at 1000 deg.C can be obtained. Consequently, the starting and a stopping of the cell can be made in a shorter time.

Title: Connection of pipe
Inventor: MIHARA KEIJI
IPC: F16L37/04
Filed: 1991-08-20
Abstract: PURPOSE:To surely prevent the slip-off and breakage of a rubber ring even if the chamfering work for a pipe insertion port is omitted, by gradually spreading the diameter of the inner periphery of the rubber ring in a pipe receiving port by a tapered part which becomes thinner towards the top edge of an insert installed at the top edge part and inserting the pipe insertion port. CONSTITUTION:An insert A is inserted into a pipe receiving port 2, and the outer surface of the tapered part 11 which becomes thinner towards the top edge of the insert A is brought into contact or set close to the inner peripheral surface of a rubber ring 3. Then, a pipe insertion port 4 is inserted into the insert A, and the top edge 41 of the pipe insertion port 4 is brought into contact with the inner surface of the tapered part 11 which becomes thinner toward the top edge, and the insert A is pushed into the pipe receiving port 2, together with the insertion of the pipe insertion port 4. When the insertion of the pipe insertion port 4 proceeds, and it passes through the rubber ring 3, the insertion of the pipe insertion port 4 is suspended, and the connection work is completed. At this time, the pressing force in the pipe axis direction acting on the rubber ring 3 can be sufficiently reduced, because of the gentle gradient of the tapered part which becomes thinner towards the top edge, and the slip-off of the rubber ring can be prevented. Further, since the top edge of the pipe insertion port 4 can be made to an arbitrary shape, the chamfering of the outer peripheral part at the top edge of the pipe insertion port 4 can be omitted.

Title: Operation control for heater
Inventor: MARUYAMA HIROSHI
IPC: F24H3/04
Filed: 1986-09-05
Abstract: PURPOSE:To reduce the fluctuating width of room temperature and improve the comfortable property of a heater, by a method wherein combustion is stopped when a primary set temperature is achieved while the combustion is started when a secondary set temperature, in which the differential of the operation of a controller is taken into consideration, is achieved. CONSTITUTION:When a room temperature is risen and the room temperature, detected by a room temperature thermistor 12, has arrived at a primary set temperature (t1) regulated by a variable resistor 13, an operation stopping signal is outputted from the terminal 14 of a large-scale integrated circuit 11 while this output is inputted into the terminal 3 of an integral circuit 17 and the ON signal of a transistor 18 is outputted from the terminal 5. Accordingly, a set temperature is determined by a value, in which the value of resistance of a room thermistor is reduced, whereby a secondary set temperature (t2) higher than the primary set temperature (t1) is determined. The room temperature is reduced by stopping combustion, however, a set temperature upon starting the combustion is (t2- t). When the combustion is started, the OFF signal of the transistor 18 is outputted and the set temperature returns to the primary set temperature (t1). Thereafter, this operation is repeated in accordance with the increase and decrease of the room temperature. According to this method, the fluctuating width of the room temperature becomes within the range of (t1) - (t2- t), smaller than (t1- t) whereby the comfortable property of heating may be improved.

Abstract: PROBLEM TO BE SOLVED: To reduce the range by which a character recognition window covers other windows and to lessen the difficulty of seeing due to mutual interference between windows of application on a display screen by making an arbitrary part in a character recognition window transparent and display. SOLUTION: In an input display part 1, user interfaces of a multiwindow system, e.g. a window 12 of a word processor and a window 11 for handwritten character recognition are displayed. The majority of the character recognition window 11 is made transparent and displayed. Namely, many parts of the character recognition window 11 except its frame line 19 and function buttons 16 are made transparent and the word processor window 12 behind it is visible. Consequently, for example, ruled lines 18 in the word processor window 12 are invisible behind the recognition character frame 13, but visible without being hidden behind an ink data input frame 15.

Title: Linear dc brushless motor
Inventor: ISODA HIDETOSHI
IPC: H02K41/035
Filed: 1994-08-08
Abstract: PURPOSE:To realize stabilized speed control and highly accurate positioning control by displacing the corresponding poles of one and the other field magnets from each other by a distance substantially corresponding to 5/6 of the pole width and then running them while coupling each other. CONSTITUTION:In the linear DC motor, the permanent magnets 21b,...,2mb of a second armature 1b are displaced from the permanent magnets 21a,...,2ma of a first armature 1a by a distance corresponding to about 5/6 of the permanent magnet 21b. The first and second magnets 2a, 2b are coupled integrally through a connecting part 4. Since the ripple of thrust generated from a pair of armature and field magnet can be offset by the ripple of thrust generated from another pair of armature and field magnet, the ripple of thrust is smoothed resulting in the stabilization of running control and highly accurate positioning control.

Title: Formation of crystal
Inventor: ICHIKAWA TAKESHI
IPC: H01L21/205
Filed: 1987-08-24
Abstract: PURPOSE:To accomplish selective growth of single crystal on only sites where nucleating surface exists, by fine forming the nucleating surface consisting of a different kind of material with higher nucleating density than that of a material of non-nucleating surface so that only a single nucleus can grow. CONSTITUTION:On a SiO2 substrate 1 with lower nucleating density as the non-nucleating surface for Si, a Si3N4 layer 2 with higher nucleating density for Si as the nucleating surface is formed sufficiently fine. A polysilicon layer 3 is deposited on the substrate 1 and the layer 2, and a SiO2 layer 4 with lower nucleating density for Si is formed on the layer 3. A resist 5 is formed on the layer 4 to carry out patterning. The layer 4 is then etched, and at a point when the polysilicon is exposed, etching is stopped with the sensing mechanism actuated to form an opening part. Thence, this opening part is oxidized to remove the polysilicon. As the next step, an acid is applied to eliminate only the oxidized film on the layer 2 and Si single crystal 6 is allowed to grow with the layer 2 as the center, being flattened to the same height as that of the layer 4, thus forming the objective Si single crystal domain 7.

IPC: G03F9/00
Filed: 1991-08-20
Abstract: PURPOSE:To improve an alignment accuracy by correcting a drift and an aberration by detecting a spare mark once plotted by an EB(electron beam) exposure system by a separate optical system. CONSTITUTION:A chip alignment mark is measured by optical systems 2, 3, a semiconductor wafer 1 is rotated, moved, and a position of a chip is aligned. A stage is moved, and a spare mark is plotted on a resist layer by an EB exposure. A position of a latent image of a diffraction grating is measured by the systems 2, 3 using a sheet beam, etc., of an He-Ne light. A difference of the measured mark position from an ideal reference position is calculated, a positional deviation and an aberration of an EB plotting system are measured, a position of a board is so regulated as to correct them to be again aligned, and then a main pattern is EB-plotted. Since a decrease in an S/N at the time of reading the alignment mark can be avoided even if a resist is flattened, a fine pattern can be accurately formed.
