Title: High-voltage transformer, high-voltage pulse generator, gas discharge lamp lighting device, illuminator and liquid crystal projector
Inventor: TAKAYA MANABU
IPC: G02F1/13
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To make a lightening of a high-voltage transformer possible and to make it possible to suppress the effect due to the thermal expansion of a resin to the minimum even if the transformer is encapsulated in a case along with the insulating resin. SOLUTION: The shape of a bobbin 30A of a high-voltage transformer 30 is formed into a one-layer winding and hollow slender shape and the section in the direction of winding of a winding is formed into a rectangular shape. Moreover, the wall thickness of the transformer 30 is gradually made thicker as it goes from the side of a low potential in a primary winding 30B to the side of a high potential in a secondary winding 30C. By forming the bobbin 30A into a square form, a transformer main body is also formed into a square form. In the case where the transformer 30 is encapsulated in a square-shaped case 32 along with an insulating resin, the thickness of a resin layer becomes even as a whole and a pressure, which is accompanied by the thermal expansion of the resin, becomes even in all of the periphery of the transformer 30.  As a gap is made it hard to form between the transformer 30 and the resin layer, a reduction in the insulation properties of the transformer can be prevented. Moreover, as the wall thickness of the transformer 30 is also changed according to the necessary withstand voltage of the transformer, a lightening of the transformer becomes possible through the transformer has a necessary and full withstand voltage property and moreover, a reduction in the cost of the transformer is contrived.

Title: Air-fuel ratio controller for internal combustion engine
Inventor: MIYASHITA KOTARO
IPC: F02D45/00
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To provide a device for conducting air-fuel ratio lean feedback control at an optimum point for obtaining the harmony between drivability and fuel consumption by conducting combustion variation limit determination which meets combustion variation detection characteristics inherent to respective engines, in an air-fuel ratio controller for internal combustion engine. SOLUTION: It is discriminated whether or not a rotational variation is larger than a first unstable combustion determination threshold value (S1601). If it is larger, the rich side correcting amount of a targeted air-fuel ratio coefficient is set to a first relatively large correcting amount (S1602). If it is smaller, it is discriminated whether or not a rotational variation is larger than an unstable combustion determining threshold value (S1603). If it is larger, the rich side correcting amount of a targeted air-fuel ratio coefficient is set to a second relatively small correcting amount (S1604). The threshold value is calculated by multiplying a mean value of rotational variation calculated at the time of stable combustion by a coefficient set according to the operating condition together.  The combustion variation characteristics corresponding to the individual difference of an engine are reflected in this threshold value, therefore, it is possible to control the targeted air-fuel ratio coefficient to the optimum point according to the individual difference.

Title: Mass spectroheter using liquid chromatograph
Inventor: MIZUNO TOKUO
IPC: G01N27/62
Filed: 1984-10-25
Abstract: PURPOSE:To prevent the contamination of an ion source, interface and vacuum evaporating part by constituting a titled device in such a manner that the outflow liquid from a liquid chromatrograph and the liquid from a liquid supply means can be selectively supplied to an ion source by a flow passage change-over means. CONSTITUTION:The outflow liquid from the liquid chromatograph 1 passes through the interface 5 and enters the ion source 2 and is then fed to a selector valve 10 when the valve 10 is in the A (solid line) state. The solvent is discarded into a waste liquid reservoir 15. The outflow liquid from the chromatograph 1 is discarded into the reservoir 15 when the rotating part 12 of the valve 10 rotates 90 deg. and the flow passage is changed over to the B (broken line) state. The solvent is fed by a liquid feed pump 13 to the interface 15 and is introduced to the ion source 2. The same solvent as the solvent used for the chromatograph 1 is fed under the same pressure and at the same flow rate by the same liquid feed pump 13 and therefore the pressure conditions in the interface 5 and the ion source 2 are maintained under the specified conditions in exactly the same state as the state A in which the outflow liquid from the chromatograph 1 is introduced. Only the component to be analyzed is thus introduced into the source 2 and the contamination is prevented.

Title: Controlling method for absorption refrigerator
Inventor: ISHIKAWA TAKEO
IPC: F25B15/00
Filed: 1988-09-08
Abstract: PURPOSE:To reduce absorption liquid concentration when the concentration of the absorption liquid become high normally while controlling an absorption refrigerator on the basis of cooling water outlet temperature and to prevent the liquid from crystallizing by reducing the quantity of heat of a high temperature regenerator irrespective of the cooling water outlet temperature when the regenerating temperature of a low temperature regenerator becomes a set value or higher. CONSTITUTION:When a controller 30 is operated on the basis of a signal from a cooling water outlet temperature detector 24 to control the quantity of heat, cooling water inlet temperature and the regenerating temperature of a low temperature regenerator are respectively detected by a cooling water inlet temperature detector 25 and a regenerating temperature detector 26. If the low temperature regenerator regenerating temperature of absorption liquid to the cooling water inlet temperature arrives at a set value, the controller 30 is operated on the basis of the signals from the detectors 25, 26 to switch the control of the quantity of heat based on the cooling water outlet temperature to a crystallization preventing control, and the opening of a heating quantity control valve 27 is reduced on the basis of the signal from the controller 30. Thus, the quantity of heat of the regenerator 1 is reduced, the concentration of the liquid is thinned, the concentration of the liquid in the outlet of a low temperature heat exchanger 6 can be reduced to prevent the liquid from crystallizing.

IPC: B23B31/20
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To machine both ends of a work. SOLUTION: In a collet chuck for a machine tool, which is able to hold or release a work 1, a main body housing 2 is provided with a work inserting hole 3 penetrating up to both front and rear surfaces of the housing 2. A ring- shaped and slotted fastening metal fitting 4, which is able to hold/grip the outer surface of the work 1 that was inserted into the inside of the hole 3, is arranged within the work inserting hole 3. A sliding tool 5 is provided between the work inserting hole 3 and the fastening metal fitting 4. In this case, the sliding tool 5 can slide within the work inserting hole 3 and in the direction of the axis of the hole 3.  Thus, the work 1 can be fastened by the fastening metal fitting 4 since the sliding tool 5 fastens the outer surface of the fastening metal fitting 4 inward when the sliding metal fitting 4 slides in one direction, while the fastening to the fitting 4 can be released when the fitting 4 slides in the other direction.
