Title: Carrier for dry process developer
Inventor: CHIBA SHUNICHI
IPC: G03G9/113
Filed: 1988-01-27
Abstract: PURPOSE:To enable formation of a good-quality image by making combination use of amorphous silica having a thixotropic effect and specific very small grain size in addition to conductive particles having a specific very small grain size as fine inorg. powder. CONSTITUTION:The powder formed by mixing and using the amorphous silica having <=20mmu (0.02mum) average grain size of primary particles and the conductive particles having <=1mum average grain size and <=200OMEGAcm specific resistance is used as the fine inorg. powder. The dispersion stability of the conductive particles in a solvent and the adhesiveness thereof to a resin are thereby improved and the easy to handle coating liquid is obtd. Since the resin coating layer can be maintained at an adequate resistance value and the defective electrostatic charge of a toner is prevented, the image staining and scumming by sticking of the carriers and conductive particles are obviated.

Title: Thin hard film and its production
Inventor: IKEDA TSUTOMU
IPC: C23C14/06
Filed: 1987-01-23
Abstract: PURPOSE:To provide a thin hard film combining high hardness with high toughness and excellent in adhesive strength to base material, by constituting a thin hard film of specific percentages of cubic BN and the borides, nitrides, or carbides of the elements of groups IVa, Va, and VIa. CONSTITUTION:This thin hard film consists of, by weight, 85-97% cubic BN (CBN) and 15-3% of borides, nitrides, or carbides of one or more kinds among the elements of groups IVa, Va, and VIa of the periodic table. In order to obtain this thin hard film, one or more kinds among the elements of groups IVa, Va, and VIa and B are simultaneously evaporated in an atmosphere containing at least N2 to undergo reactive vapor deposition onto a material to be treated. It is necessary to regulate the ratio between the above CBN and the above borides, nitrides, or carbides (internal stress relaxation components) to a value in the above range, and film hardness is deteriorated when CBN content is less than 85%. On the other hand, effects of functions such as internal stress relaxation, improvement in toughness, etc., cannot be obtained when CBN content exceeds 97%, because the amounts of internal stress relaxation components are too small.

Title: Facsimile equipment
Inventor: SUZUKI ATSUSHI
IPC: H04N1/00
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To provide a facsimile equipment whereby a line with a telephone station is prevented from being occupied for a long time when dialling is executed to the dial number of an opposite party side which is not connected. SOLUTION: A picture information is transmitted to the facsimile equipment of the opposite party side and picture information transmitted from the facsimile equipment of the opposite party side is received in the facsimile equipment. In the equipment, the line is disconnected by detecting a voice message which is transmitted at the time of dialling the dial number being usage impossible (St. 17) a redial function is stopped (St. 19) and also a user is reported that the dial number of the opposite party side is usage impossible (St. 20). Thus, repeated dialling for many times to the dial number of the opposite party side which is not connected is prevented.

Filed: 1980-02-08
Abstract: PURPOSE: To increase the area of heat conduction and also to enable stabilization of generation of steam bubbles by forming a space part having a shape widening toward the depth in the boiling heat conduction surface used in a boiler, a freezer or the like.  
     CONSTITUTION: A number of parallel angular grooves 2 are formed in the boiling heat conduction surface 1 contacting with liquid A such as Freon liquid or water. Each angular groove 2 has a trapezoid cross section widening toward the depth. Since the boiling heat conduction surface 1 is to have the angular grooves 2 by such formation, the heat condction surface is increased in comparison with simply smooth boiling heat conduction surfaces and, in addition, a stable mode of generation of a foaming cavity (a) as the steam bubble is obtained. When the boundary face (b) between the liquid A and the foaming cavity (a) meets the condition of a concave surface (θ>π/2-ϕ) and the liquid intrudes into the cavity (a) having the form widening toward the depth, the pressure of the air bubble is reduced sharply. And, when saturation temperature corresponding to the pressure is lower than the local temperature of the cavity part, condensation is prevent.

Filed: 1989-01-25
Abstract: PURPOSE:To obtain the oriented film which can extremely adequately control the orientation of liquid crystal molecules by irradiating the surface of the high-polymer film on an electrode substrate with a high-intensity UV layer, thereby forming periodic patterns. CONSTITUTION:The surface of the high-polymer film of the electrode substrate of a liquid crystal display device is irradiated with the high-intensity UV laser to form the periodic patterns. Arom. polyether sulfone, arom. polyimide and arom. polyester are used as the high-polymer film. XeF, XeCl, KrF, ArF or F2 excimer laser is used as the UV layer. The beam is passed through a mask (metallic pattern) in order to form the periodic patterns. The swarf by the laser splashes at a high speed and does not stick. The cutting depth is controllable by a laser wavelength, effluence and pulse number. The ruggedness which is physically and chemically stable is thus formed.

Title: Measuring device of length of long object
Inventor: SHIMIZU ISOYUKI
IPC: G01B21/02
Filed: 1990-01-25
Abstract: PURPOSE:To enable measurement of the length of a long substance by a single measuring device, by calculating the length of the substance to be measured, on the basis of detected values of the measuring device obtained when it is detected that first and second end part detecting elements come into contact with the end parts of the substance to be measured. CONSTITUTION:When a rod 22 of an air cylinder 14 is withdrawn in the direction of an arrow B, a first sprocket wheel 10a rotates in the direction of an arrow C and a second sprocket wheel 10b in the direction of an arrow D. Thereby end part detecting elements 2 and 3 linked to forward and backward ways of a rotary body 13 are moved inward respectively and approach each other. When the detecting elements 2 and 3 come into contact with a steel pipe 1, contact parts 17 move back against the actuation of springs 19 respectively and a metal plate 21 traverses a position in front of a proximity sensor 20. In a state wherein the detecting elements 2 and 3 hold the steel pipe 3 between, any metal plate 21 is detected by the sensor 20 and a processing device reads the data of an encoder 16 on the occasion and calculates the length of the steel pipe 1. Since the detecting elements 2 and 3 approach each other when an endless body 12 is driven, in this way, the length of the steel pipe 1 can be measured only by providing the single encoder 16.
