Abstract: PURPOSE:To enable to obtain hot water of a high temperature from the upper half of a tank and hot water of a low temperature from the lower half of the tank, by constituting two kinds of water circuits. CONSTITUTION:Superheated coolant discharged from a compressor 10 forms a refrigeration cycle through which the superheated coolant is decompressed by a decompressor 13 after condensation of the same in the first water coolant heat exchanger 11 and the second water coolant heat exchanger 12 and then evaporated by an air coolant heat exchanger 14, which is sucked again into the air compressor 10. On the one hand, the water pumped up from the lower part of a tank 17 by the first pump 18 forms a water cycle through which the water is returned again to the upper part of the tank after it has been sent to the first water coolant heat exchanger 11, and the water pumped up from the lower part of the tank 17 by the second pump 20 forms a water cycle through which the water is returned again to an intermediate part of the tank 17 after it has been sent to the second water coolant heat exchanger 12. As the water quantity to be streamed through the first water coolant heat exchanger 11 is designed to be rather small beforehand and further heat exchange between the water and superheated gas which is a coolant, is performed, the hot water of a high temperature is obtained and the hot water whose temperature is different from that of hot water to be obtained through the second water coolant heat exchanger 12 is obtained.

Title: Dry-etching device for pyroelectric material
Inventor: TOYODA SHINICHIRO
IPC: H03H3/08
Filed: 1988-06-21
Abstract: PURPOSE:To reduce the instantaneous temperature changes of a pyroelectric material and convey the pyroelectric material easily by providing several protrusions on a tray on which a pyroelectric material substrate of a sample to be etched is put or on a substrate electrode so that the pyroelectric material substrate may come into point-contact with them. CONSTITUTION:A tray 16 provided with protrusions 15 is put one a substrate electrode 2, and a pyroelectric material substrate 8 being a sample to be etched is put on the tray 16 through the medium of the protrusions 15. Though the pyroelectric material 12 is polarized electrically through the pyroelectric effect produced with the heat by a physical-chemical reaction of a reaction gas plasma, the protrusions 15 on the tray 16 or electrode 2 prevent the electrostatic attraction. This reduces the instantaneous temperature changes of the material 12, and makes it possible to convey the material 12 easily.

Filed: 1989-06-15
Abstract: PURPOSE:To effectively attract electrified toner to a developing roller and to smoothly carried out black solid printing by providing a conductive electrode member and applying an electric field to between a latent image carrier and it. CONSTITUTION:One-component toner is stored in a toner hopper 3, carried to a toner supplying roller 6 by an agitator 4, electrified through friction with the surface of the developing roller 5, and attracted therto. Then, the electric field is produced by impressing a voltage between the conductive electrode member 7 and the developing roller 5, and the toner is attracted to the developing roller 5. This toner is carried to an developing area near a photosensitive drum 1 while it is almost regulated to one layer by a layer thinning regulation member 9. Since the conductive electrode member exists, a space is eliminated from the toner attraction to the developing roller, and therefore, preferable black solid printing is possible.

IPC: B22C3/00
Filed: 1982-09-04
Abstract: PURPOSE:To obtain a core for casting a light alloy with which the stripping of a film does not arise in the stage of casting by hardening molding sand with a binder and molding the sand then coating water glass emulsified with Al2O3 powder and Al powder thereon and calcining the sand thereby adhering the heat resistant film thereto. CONSTITUTION:A binder of a thermosetting resin or a resin curable by chemical reaction is mixed with molding sand and a core 1 is molded and hardened. Water glass mixed and emulsified with Al2O3 powder and Al powder is coated on the surface of the core 1 to form a mold coating material layer 2 and to penetrate part thereof in the surface layer part of the core 1, thereby forming a penetrated layer 1a. Such molding sand is calcined at 300-400 deg.C to stack and adhere the Al2O3 powder and the half molten Al in the layer 1a and the layer 2 and on the surface and surface layer part of the core 1, thus forming a tough and strong air permeable film having heat resistance. The sand and metal penetration in the stage of casting such as die casting of a light alloy is prevented by using such core.

Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To enable high-accuracy optical density detection by integrally holding a light emitting element and a photo detecting element by a holding member, and moving the holding member between both first and second measuring positions. SOLUTION: When a solenoid of an actuator 11 is not excited, a turning part 111b is arranged to be vertical to a photoreceptor drum 21, and an AIDC sensor 64 is put in a first measuring position. On the other hand, when it is excited, an operating shaft 112a is moved to the main body 112b side, and the turning part 111b is inclined to the outer peripheral surface 21a of the photoreceptor drum 21, that is, it is put in a second measuring position where the light emitting and entering surface of the AIDC sensor 64 is inclined to the outer peripheral surface 21a. Thus, a lever member 111, the solenoid type actuator 112 and a coiled spring 113 operate as a holding member moving mechanism.  That is, in the state of keeping the relative positional relation between the light emitting element and the photo detecting element, the AIDC sensor 64 can be moved between both first and second measuring positions, and optical density measurement can be made in the respective positions so as to simplify the mechanism of the device and attain low-priced constitution.

Title: Sealing device
Inventor: TAIRA ITSUKI
IPC: F16J15/56
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To form a surface pressure distribution showing satisfactory sealability by energizing a sliding surface by the use of diametral component force which is generated when opposed surfaces are abutted to each other due to axially relative motion of a projected line and flanges. SOLUTION: When a projected line 102c and flanges 2c, 2d 7 of a sealing device are axially moved and abutted against each other by the relative motion of two opposed surfaces or pressure of sealed fluid, diametral component force A1 is generated for pressurizing the sliding surface. When the sealing device is used, the diametral component force A1 increases a surface pressure distribution PD1' on the side of the flange 2c, and improves sealability. The component force A1, generated by reciprocation of a shaft in respect to a housing, improves both of the surface pressure distributions PD1' and PD2. High surface pressure is shown in the forth motion where sealability is required. The surface pressure is decreased in the back motion where sealability is not so required, for performing lubrication. Sealability of the device is thus improved with such a simple setup.
