Title: Synchronizing addition circuit
Inventor: OKIGUCHI KOTARO
IPC: H04N5/06
Filed: 1991-09-19
Abstract: PURPOSE:To realize low power consumption with the minimum number of ROMs by providing a means corresponding to a circuit digitally adding a synchronizing signal to a circuit by an arbitrary DC level. CONSTITUTION:The address generated by a counter 5 is added to a common ROM 6, and latched by a latch 2. A synchronizing signal 12 adjusting the setup level by an adder 9 is added to one input of a synchronizing signal addition circuit 1, a changeover signal 13 of a video signal 11 and a synchronizing signal 12 is added, obtaining a signal 14 adding the synchronizing signal 12 to the video signal 11. Thus, the power consumption can be reduced while minimizing the ROM even when the number of systems is increased by providing the adder 9 as a means sharing the ROM 6 and making the setup level different. By digitally embedding a synchronizing signal, a circuit with stable operation can be obtained.

Title: Optical head device
Inventor: FUJINO YOUSUKE
IPC: G11B7/135
Filed: 1996-10-08
Abstract: PROBLEM TO BE SOLVED: To enhance the utilization efficiency of light, facilitate downsizing, improve productivity and allow low-cost production by placing an transmissive scattering type liquid crystal element which has a substrate gap within a specified range between the beam splitter and the optical recording medium and thereby changing the aperture diameter electrically. SOLUTION: Light going out from a light source 1 passes a condenser lens 2, a beam splitter 3, and an aperture diameter controlling element 4 to be condensed by a condenser lens 5 and reaches the optical recording medium. Here by changing the voltage to be impressed on the element 4, the aperture diameter of the element 4 is varied to adjust the focus on a first or a second optical recording medium 6, 7. The element 4 is formed by injecting transmissive scattering type liquid crystal between the opposing substrates having electrodes. The gap of the opposing substrates is set at 2-10μm to evade ill effects due to deformation and maintain scatterability. By this, a high efficiency of optical utilization is acquired and making it unnecessary to switch the focus by the mechanical movement of the condenser lens 5, enabling downsizing.

Title: Indwelling tube in organism and its manufacture
Inventor: KASAI HIROAKI
IPC: A61M1/00
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To prevent the adhesion of various materials to the inner surface of a tube so as to hardly cause the internal clog by introducing a hydrophilic group to at least the inner surface of the tube. SOLUTION: A PTFE stored tube is dipped in a reforming medium 3 within a vessel 2, and ultraviolet ray 5 is irradiated thereto. The energy of the ultraviolet ray 5 absorbed in the stored tube 1 is absorbed by a chemical bond constituting a fluorine resin, particularly, C-F bond or C-F3 bond connected to -C main chain skeleton, and the bond is cut to separate F. On the other hand, since the reforming medium 3 is pure water, the ultraviolet ray 5 is absorbed by O-H bond and mostly decomposed to H and OH. Since the atom or radical made free by cutting the bond is chemically unstable, it is apt to recombine with the other atom or radical. Since the recombination preferentially advances from the combination having a high bond energy, H and F are preferentially recombined, and OH is recombined to C.  Consequently, the inner surface 1b of the indwelling tube 1 is reformed to hydrophilic property.

Abstract: PURPOSE:To reduce the manual work quantity of a maintenance man so as to overcome a fault accompanied by manual work by providing an automatic memory dump execution instruction mechanism giving an instruction to automati cally start a memory dump processing to a basic operation device when a system is down. CONSTITUTION:When system-down occurs, a system down detection mechanism 1 detects it, the automatic memory dump execution instruction mechanism 2 is started and the instruction is given to the basic operation device 21 so that the memory dump processing 3 is started.

It judges whether the processing is executed automatically or by a manual operation, and judges whether a memory dump output device is set or not. When it is set, memory dump is automatically extracted to the memory dump output device and a system waits for system reraising. Thus, a problem that there is an obstacle to the resumption of business when the system is down can be overcome.

Title: Method for constructing information system and its expressing method
Inventor: KOSAKA MITSUTAKA
IPC: G06F19/00
Filed: 1990-10-08
Abstract: PURPOSE:To construct an information system based on the effect of information by introducing such a concept that information power varies depending upon the intensity of the field of information which requires information and the kind of the information. CONSTITUTION:A formula, information power = (intensity of field of information) X (kind of information), is established and, in order to obtain information power having a larger effect, an information system is constituted so that the intensity of the field of information can utilize stronger information. Namely, for constructing the information system, an information system having a function 1 which measures and evaluates the intensity of a field of information and another function 2 which produces the most effective information evaluated by the function 1 is constructed. In addition, in order to most effectively utilize produced information, a function 3 which controls the intensity of the field of information is also incorporated in the information system. Therefore, the information system thus constructed can sufficiently take the effect of information into consideration.
