Title: Information detector
Inventor: HAYASHI KATSUHIKO
IPC: G06K7/10
Filed: 1988-05-06
Abstract: PURPOSE:To simultaneously read the data of large quantity and to erase necessity to operate a medium at a high speed by simultaneously observing areas on the medium, to which the data of the large quantity are recorded, with an image pick-up device. CONSTITUTION:When one part of a medium 1 is enlarged by a convex lens 2 and an enlarged picture is projected on the image pick-up surface of a solid image pick-up element 3, the solid image pick-up element 3 is caused to be an image pick-up condition by a control device 4. Next, the control device 4 transfers the concentration information of the surface of the medium, which is image picked-up to the solid image pick-up element 3, to an analog digital converting device 5. At such a time, since a potential according to information, which are recorded to the medium surface with concentration, is outputted from the solid image pick-up element 3 sequentially, this potential is quantized by the analog digital converting device 5. Then, by outputting the potential from an output terminal 6, the information to be recorded to the medium surface can be detected as a digital value. Thus, since the data of large quantity can be simultaneously read, it is not necessary to operate the recording medium at the high speed.

Title: Earthquake-resisting bed
Inventor: TANABE HIROMASA
IPC: A47C19/04
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To support furniture fallen at the time of an earthquake by a frame main body and safely protect a sleeping person on a bed main body by separating a bed into the frame main body and the bed main body and supporting only the bed main body so that the bed main body may be lowered at the time of the earthquake. SOLUTION: Pipes and legs (frame main body) of a bed and a bottom plate and a mat 1 (bed main body) of the bed are separated. The frame main body is made to support the bed main body by four legs constituted of hinges 4 at three places. Because the intermediate hinge 4 bends inward when an earthquake occurs, the bed main body is lowered. As a result, fallen furniture and broken beams are supported by the surrounding frame main body and a sleeping person can be safely protected.

Abstract: PURPOSE:To improve easy-to-use operations as well as to prevent erroneous operations by letting the actuating unit of a cooking container actuate the switching section of a main body, and thereby letting revolutions agreeable to the cooking container be selected when the cooking container is engaged with the main body. CONSTITUTION:When mixing function is performed, a mixing container 11 is engaged with a main body 1 so as to let a main switch 5 be turned on. In this case, the engaging section 10 of the mixing container 11 comes in contact with the upper surface of the main body 1, but an actuating unit 18 does not come in contact with a movable body 6. Namely, this permits the switch 7 of a control section 23 to be closed so that a Low coiled wire 24 is short- circuited, and a High coiled wire 25 allows high revolutions to be outputted. When function as a cooking cutter is performed, a cooking cutter container 19 is engaged with the main body 1 with a main switch 5 turned on. In this case, the movable body 6 is pressed by an actuating unit 18' so as to let the switch 7 be pressed by the movable body 6 for letting a switch 8 be opened so that low revolutions are outputted.

Abstract: PROBLEM TO BE SOLVED: To obtain a water-base ink composition capable of being controlled in wetting properties, surface tension, etc., and also in antibacterial properties, etc., in spite of having a simple composition by including a semi-polar boron compound. SOLUTION: The semi-polar boron compound is typified by a diglycerol borate represented by formula I. It may be a derivative of a diglycerol borate. It is exemplified by a compound of formula II, prepared by reacting diglycerol borate with a fatty acid (e.g. glycerol monolauroylglycerol borate or glycerol monopalmitoyl glycerol borate). The semi-polar boron compound possesses also antibacterial properties. The most suitable range of the amount of the semi-polar boron compound added varies with the colorant contained in the water-base ink composition. Desirably this amount is 0.5-3.0 wt. % based on the total weight of the ink composition when the colorant is a dye, while it is 0.05-10 wt.% based on the composition when the colorant is a pigment.

Title: Method and apparatus for production of compound crystal film
Inventor: FUJIYASU HIROSHI
IPC: C30B25/02
Filed: 1984-05-31
Abstract: PURPOSE:To obtain a uniform and homogeneous compound crystal film having high purity, easily, by supplying vaporized plural materials to the thermal film-forming chamber having closed top-opening, in a vacuum chamber, and placing a heated substrate to the top-opening thereby forming a compound crystal film, wherein said crystal film is exposed to vacuum once or more times during the deposition of the crystal film. CONSTITUTION:In the case of forming a compound crystal film such as ZnS film, Zn and S are put into the circumferential crucible 4 and the core crucible 5, respectively. Thereafter, Zn and S are heated at or above the respective boiling points to fill the film-forming chamber with the vapor of Zn and S. Whe the pressure in the chamber is raised to a prescribed level, the substrate holder 20 is shifted as shown in the figure B until the substrate-holding part 22 is positioned at the top-opening 25 of the chamber 3. A ZnS crystal film is deposited to the lower face of the substrate 24 by this process. When the ZnS film is grown to an extent, the holder 20 is returned to the position of the figure A to expose the substrate 24 to the vacuum in the vacuum chamber 1 to evaporate and remove the attached impurities. Thereafter, the substrate 24 is shifted again to the position of the figure B to continue the growth of the crystal film until the thickness of the film reaches the prescribed level.

Filed: 1990-04-26
Abstract: PURPOSE:To attain the application of a single-port RAM to the RAM to which a microcomputer has an access by applying an access to a display address of the RAM in a non-access period and reading out the data held by a display data holding circuit in an access period. CONSTITUTION:The display address of a RAM 1 receives an access in a non-access period when the calculation address of the RAM 1 receives an access in an executing period of a prescribed instruction. Meanwhile the latch data are read out of a shift register 12 serving as a display data holding circuit in an access period when the calculation address of the RAM 1 receives an access in an executing period of a prescribed instruction respectively. Thus a single port RAM can be applied to the RAM 1 and no dual port RAM is needed. As a result, the increase is prevented for the chip size of a microcomputer.
