Title: Focus servo pull-in system for optical pickup device
Inventor: MORIWAKI ISAMU
IPC: G11B7/085
Filed: 1988-11-16
Abstract: PURPOSE:To reduce the automatic focus servo pull-in time by recording a signal level at a focal point of an objective lens for the execution again of a discrimination of the focal position of the objective lens based on the recorded signal level on such occasion. CONSTITUTION:A focus track servo control section 205 controls an actuator 203a to discriminate a focal position of an objective lens while moving the objective lens. Then a system control section 212 stores a signal level of a drive signal with respect to the actuator 203a at the focal position. Then in the case of executing the discrimination of the focal position again, the control section 212 moves the objective lens from a position in the vicinity of the preceding focal position based on a signal level to be stored by means of the actuator 203a. As a result, the time to find out the focal position is reduced. Thus, the focus servo pull-in time is decreased.

Title: Vacuum casting method and device thereof
Inventor: KANDA KOKICHI
IPC: B29C39/42
Filed: 1989-11-06
Abstract: PURPOSE:To realize the sure and rapid pouring of resin in the interior of a mold and reduce the generation of malformation and inferior surface by a method wherein mixture is once stored in a storing part, which is provided so as to communicate through an opening and closing means with an inlet formed on a mold, and, after the pressure on eth storing part side is elevated, poured by opening the opening and closing means. CONSTITUTION:After the whole amount of mixture in a container 6 is cast in a storing means 30, the internal pressure in a mixing chamber 1 is raised to the predetermined pressure. The raising of pressure is performed by closing an exhaust valve 10 attached to the mixing chamber 1 in order to cut off the communication between a vacuum source 5 and the mixing chamber 1 and, at the same time, by opening an intake valve 11 in order to introduce the air. Thus, the mixture stored in the storing means 30 is poured through a solenoid valve 4, a connecting means 31 and an inlet 80 in a mold 8. Since the pouring is performed by the gravitational effect caused by the difference of altitude between the storing means 30 and the mold 8 and, at the same time, by the difference of pressure between the mixing chamber 1 and a mold chamber 2, in which the storing means 30 and the mold 8 locate respectively, the mixture is rapidly and surely filled in the internal space of the mold 8.

Inventor: YOSHIDA MINORU
IPC: H04L12/70
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To provide technology which can transmit data on a realtime basis, can execute bi-directional communication between a transmission station and a master station (repeater station) and can also send data besides the remote maintenance and observation data. SOLUTION: This communication method uses a satellite line. When data is to be transmitted from the transmission station 1, a packet where data and the identifier of the self-station are stored is individually transmitted to the master station 4 at every transmission station by a concentration system satellite line. When data is transmitted from the master station 4 to the specified transmission station, packets where data and the identifiers of transmission destinations are stored are multiply-addressed to the respective transmission stations by multi-address system satellite lines. The packets are received in the respective transmission stations and data are discriminated to be those which are addressed to the self stations from the identifiers of the received packets. Thus, bi-directional communication is executed between the plural transmission stations and the master station.

Abstract: PURPOSE:To manufacture an electrodeposition coated molded product by forming a thermoplastic resin film having specified conductivity into a good shape, setting the same in a mold, forming a resin layer, forming a two-layer molded product and applying electrodeposit coating on the conductive thermoplastic resin film side. CONSTITUTION:A conductive thermoplastic resin film having conductivity of 10<3> OMEGA.cm or less of volume resistivity is formed into the given three-dimensional shape by the vacuum forming method, air pressure forming method or the like. The proper thickness of thermoplastic resin film having conductivity is in the range of 10 - 1,000 mu. When thinner than said range, throwing power of a coating material at the time of electrode position in the post-process gets poor, while thinner than said range, mechanical strength of a molded product gets weak. The molded product is set in a mold and a resin layer is formed by the method such as injection, compression or casting to shape up a two-layer molded product, and further electrodeposition is applied on the conductive layer side. Cation electrodeposit coating or anion electrodeposit coating is applied as the electrodeposit coating, and recently epoxy resin group cation electrode posit coating is applied widely. Fragility of a high conductive material can be eliminat ed by said process to manufacture a product of sufficient mechanical strength and good appearance.

Filed: 1988-11-16
Abstract: PURPOSE:To make it possible to measure the coefficient of cross-sectional shape of fiber in a short time by combining a projection microscope and a coordinate-input device through a reflecting mirror, and further combining the coordinate-input device and an operating device. CONSTITUTION:The preparation of the cross section of a fiber is mounted on the stage of a projection microscope 1. When the focal point is adjusted, the preparation image of the cross section of the fiber is formed with transmitted light. Then a projected light beam (a) of the preparation image of the cross section of the fiber is reflected with a reflecting mirror 2. The light beam is projected on the surface of the coordinates of a coordinate input device 3. Then, the point of the outer shape of the image of the cross section of the fiber is determined. The coordinate points are determined with a coordinate- point specifying end (cursor) 3'. The specified coordinate point data are inputted and operated in an arithmetic processing unit 4. Thus the coefficient of the shape is computed. The results of the operations (f) are outputted to a display 5' and a printer 5''. In this way, the coefficient of the shape of the cross section of the fiber can be measured accurately in a short time.

Abstract: PURPOSE:To prepare a superhigh strength concrete by curing a viscous ready mixed concrete exhibiting a low water-cement ratio under a condition where the concrete is covered with water or an aqueous solution of a lime-based material so as to prevent vaporization of water and subsequently curing it in a high-humidity atmosphere. CONSTITUTION:A viscous ready mixed concrete prepared by blending water or an aqueous solution of a lime-based material with one or two or more components selected from a water- reducing admixture, a foaming agent, a light aggregate and a fiber and exhibiting a low watercement ratio is subjected to a treatment for preventing vaporization of water, e.g. by covering the mixed concrete with water or an aqueous solution of a lime-like material as immediately as possible after the concrete is hardened enough to be prevented from collapsing by water. Under this condition, the mixed concrete is cured and hardening is successively carried out by curing it in a high-humidity atmosphere after releasing it from the mold or without releasing it. For example, 450 pts.wt. cement, 50 pts.wt. fine powder of silica sand, 500 pts.wt. sand, 20 pts.wt. aminosulfonic acid-based highperformance water-reducing admixture and 115 pts.wt. water are kneaded and charged into a frame mold. Immediately after molding, a cover is placed thereon and curing is carried out in a tightly sealed state. After passage of 5hr, the resultant concrete, together with the frame mold, is immersed in lime water. It is released from the frame mold after 24hr from molding, then further immersed in lime water for 2 days and subsequently cured in the air of 100% humidity for 2 days. The resultant cured concrete exhibits 1060kgf/cm<2> of two week compressive strength.
