Title: Body fluid processor and its preparation
Inventor: KAWANO TAKUMI
IPC: A61M1/18
Filed: 1995-05-01
Abstract: PURPOSE: To improve processing efficiency of a body fluid by a method wherein hollow fiber membranes are wound spirally on a winding core through a mesh and they are loaded into a housing and a fixing agent is poured into both ends and both ends of the hollow fiber membranes are opened by cutting the both ends of the fixing agents to form an inlet and outlet of the body fluid. CONSTITUTION: Hollow fiber membranes 5 bound into a belt-like shape are wound spirally on the outer periphery of a cylinder and removed and stretched flat and then, they are wound on a winding core 6 with inclined faces 6a and 6b on its end parts along the spirally wound direction through a mesh-like spacer 7. Then, the wound hollow fiber membranes 5 are loaded into a housing 2 and are fixed in the housing by pouring a fixing agent 8 on both ends and the both end parts of the hollow fiber membranes 5 are opened by cutting the both ends of the fixing agent 8. Finally, ports 3 and 4 each with an inlet 11 and an outlet 12 are mounted on both ends of the housing 2. It is thereby possible that a body fluid processing liq. flowing thereinto from the inlet 9 of the port 3 can uniformly flow into the end part of the hollow fiber membranes 5 along the inclined face 6a.

IPC: H04N5/92
Filed: 1987-05-29
Abstract: PURPOSE:To surely reproduce both an analog and a digital picture information signals recorded on a recording medium with different recording systems, by using a digital signal processing means via a conversion means at the time of performing the reproduction processing of the analog picture information signal. CONSTITUTION:At the time of recording, an input video signal is introduced to an A/D converter 4, and it is converted to digital data. Next, a data quantity is reduced to around 1/4 by using a band compressor 6A. And at a redundant code attaching circuit 6B, an error correction code is attached as a countermeasure for a transmission error or dropout, etc., following magnetic recording/ reproduction. At the time of reproduction, a waveform equalization processing is performed at a demodulation circuit 22C, and the data is restored to its original code system by applying conversion opposite to that at the time of modulation. Thus, the A/D converter being already provided in a recording side circuit for recording a digital signal is shared. Similarly, a reproducing digital signal processing circuit 22 being already provided for reproducing the digital signal and a D/A converter 24 are used as they are.

Title: Semiconductor device
Inventor: NISHIDA TAKASHI
IPC: H01L23/52
Filed: 1982-07-30
Abstract: PURPOSE:To improve the reliability of a high molecular resin-sealed device by forming high moisture resistance wirings of an alloy of Ni, si of specific compositions by weight and the residue of aluminum on a semiconductor substrate. CONSTITUTION:A wiring layer which contains 0.01-2.5wt% of Ni, 0.5-4wt% of Si and the residue of aluminum is formed on a semiconductor substrate which has a PSG or high molecular resin layer on the surface. Preferably, Ni is 0.1-1wt%, Si is 1-2wt%. If the contents of the Ni and Si are out of these range, the moisture resistance decreases. When the wiring layer is covered with polyimide and/or PIQ resin, the heat resistance is improved. This composition can effectively perform the effects in case of resin sealing, and even when this is applied to a multilayer wiring structure, the moisture resistance and reliability can be extremely improved.

Abstract: PROBLEM TO BE SOLVED: To prevent creeping of a bonding agent into the lower surface of lenses and to prevent optical distortion of the lenses by providing a plurality of fixing pawls for holding objective lenses and then coating the area between the upper surface and side surface of lenses with a bonding agent. SOLUTION: A plurality of fixing pawls 55 for fixing objective lenses 23 are integrally provided on the upper surface on a lens fixing means 38a. The pawl 55 holds the bonding agent 57 between the lens 23 and side surface and is composed of a pawl 55a for bonding to fix the lens 23 and pawl 55b for positioning to prevent falling of the lens 23 by holding the external circumference of the lens 23.

The pawl 55b is lower than the height of lens 23, while the pawl 55a is lower than the pawl 55b and width of the pawl 55a is wider than that of the pawl 55b. The area between the upper end surface of pawl 55a and the side surface of the lens 23 is coated with a bonding agent 57 to fix the lens 23 to the fixing means 38a.  In this case, since the inclined surface is formed at the upper end part of the pawl 55a, a large amount of bonding agent 57 can be held to increase a bonding force.

Title: Sensitive material carrier device for image recorder
Inventor: SHIMAOKA HITOSHI
IPC: G03B27/46
Filed: 1987-05-28
Abstract: PURPOSE:To keep a developing process speed constant and also to minimize a device by intermittently driving a belt which carriers a sensitive material and forming intermittently a loop at the entrance of a developing process part by the sensitive material. CONSTITUTION:A limit switch 118 is provided on a guide plate 108 on the exit side of the intermediate carrier device 100 for the sensitive material S to detect the height of the sensitive material S. Since the sensitive material S is carried at speed V2 higher than the developing process speed V3 by a belt 102, the material S gradually forms the loop upward to contact with the switch 118, which becomes on, then the belt 102 is stopped once. When the loop descends to be a lower limited value, the switch 118 becomes off and the belt 102 is intermittently and fractionally driven. Therefore, the developing process speed of the sensitive material S is always kept constant and also the device can be minimized because only one switch is needed.

Title: Resource utilization system on computer network
Inventor: MAEDA KATSUYUKI
IPC: G06F17/30
Filed: 1997-05-06
Abstract: PROBLEM TO BE SOLVED: To delete information needed for recording and to use resources even if actual resource use information is altered after being recorded on a record medium by administering the resource use information by a computer system, recording information for referring to the resource use information on a recording medium, and making an inquiry by the computer system when resources are used. SOLUTION: A resource use information provision system determines an index for referring to the resource use information and records the resource use information and index on the record medium. A user terminal to use resources inputs the index recorded on the record medium and inquires the resource use information of the resource use information provision system. The resource use information provision system retrieves the resource use information corresponding to the index of the inquiry and informs the user terminal of it. The user terminal makes use of the resources of the service provision system by using the reported resource use information.
