Title: Mat device
Inventor: URASAKI JUN
IPC: E01F9/524
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To effectively use a mat as various information media such as an outdoor propaganda-advertisement or guide means by arranging light emitting parts or light reflecting parts visible from the outside of the mat on the mat. SOLUTION: A mat M is formed as a grating-shaped square frame body as a whole out of a large number of main bars 2M juxtaposed at equal intervals in the lengthwise direction of a flat groove P and plural cross bars 2C to separate these main bars 2M from each other. Plural light emitting diodes LE as light emitting parts mutually juxtaposed at intervals in the lengthwise direction are provided. In this way, since the light emitting parts LE or light reflecting parts visible from the outside of the mat M are arranged on the mat M, in a comparatively and easily attractive mat M existing in a position lower than a line of sight of a passerby, the light emitting parts LE themselves emit the light. Therefore, the mat can be effectively used as an information media such as a propaganda-advertisement or a guide to a passerby.

Title: Electronic still camera system
Inventor: TABEI MASATOSHI
IPC: H01L27/14
Filed: 1987-02-13
Abstract: PURPOSE:To photograph a high quality image with simple constitution by accumulating on a nitride film charges emitted from a monocrystal semiconductor layer on which the optical image of an object is radiated, and detecting the electrostatic capacity of a depletion layer being generated. CONSTITUTION:An optical image is formed on a transparent conductor layer 9 then made incident to a high resistance semiconductor layer 8 through the layer 9, and the resistance of the layer 8 varies corresponding to the illuminance of light, and a voltage corresponding to the formed pattern of the optical image is impressed on a nitride film 6. Accordingly, a charge pattern is generated corresponding to the variation of the voltage, at the same time, the depletion layer 14 caused by said charge distribution 13 is formed in the monocrystal semiconductor substrate 4 through an oxicide film 5. This charge distribution 13 and the depletion layer 14 are equivalent to a latent image, and is maintained even if unloaded from the equipment after image pickup and voltages VDD, VEE are no longer impressed. This is because the charges discharged from the substrate 4 to the nitride film 6 is held. The reproduction of the image is executed by detecting the electrostatic capacity of the depletion layer 14.

Title: Memory protection system
Inventor: SUZUKI HITOSHI
IPC: G06F12/14
Filed: 1981-03-04
Abstract: PURPOSE:To simplify alteration processing by changing memory protection information without requiring a control program. CONSTITUTION:A control register 7 stores address X and, for branch addresses in a table area located upper than X, a user's program permits to access to a control program area. A comparator 8 compares whether the address of an address register 6 is smaller than that of the control register 7 or not and, when the address is smaller, generates a signal to transmit it to AND gates 9, 10. A signal line 11 out of outputs from the decorder 7 which shows a branch command to a subroutine is transferred to the AND gate 9. Thus when the subroutine branch command is the one to the upper table area than X, a signal indicating protection information change is given to a signal line 12.

Filed: 1989-02-09
Abstract: PURPOSE:To make absorbable noises in medium-pitched sound of heavy floor impact sound arising from floor vibration by providing reinforcing members to the underside of a floor board at positions roughly at the middle of, and in parallel with the adjoining floor beams. CONSTITUTION:A rectangular outer frame is formed of four floor girders 23. A plurality of floor beams 24 are then fixed, in parallel one another, to the floor girders 23 and a floor board 25 is directly fixed thereon. Then furring strips 27 are joined and fixed to the lower end faces of the floor beams 24 and a ceiling board 28 of the lower story is installed thereunder. Reinforcing members 29 are joined, with adhesive or by nailing, to the underside of the floor board 25 at positions roughly at the middle of, and in parallel with the adjoining floor beams 24. As the main cause for noises by medium-pitched sound arising from floor vibration will be the vibration of the floor board 25, the floor board 25 is reinforced with the reinforcing members 29. Thereby the medium-pitched heavy floor impact sound can be decreased by curbing the vibration of the floor board 25, which in return results in improvement of habitability.

Title: Compression auto-ignition engine and the control means thereof
Inventor: AMANO TOSHIJI
IPC: F02P23/02
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To be able to achieve stable operation by providing nitrogen oxides that promote auto-ignition, or ozone which reacts with the air and generates nitrogen oxides in the combustion chamber in a compression auto-ignition engine which auto-ignites and burns instantaneously in the combustion chamber. SOLUTION: During operation of an engine 10, the cylinder pressure in the engine 10 is detected by a pressure sensor P1. The timing of the auto-ignition is calculated in a control unit 26 based on the detected pressure, and it is determined whether or not the calculated auto-ignition timing is correct. Here, if the self-ignition timing is fast relative to the correct timing, the opening of an open/close valve V1 closes and the atmosphere of the combustion chamber BS should shift to one that makes auto-ignition difficult, reducing the supplied amount of NOx or ozone. On the other hand, if the auto-ignition timing is late relative to the correct timing, the opening of the open/close valve V1 widens so as to increase the amount of NOx or ozone generated. As a result, stable operation of a compression auto-ignition engine is ensured.

Title: Engine air intake system
Inventor: YAMAMOTO HIDEHIKO
IPC: F02M35/10
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To provide an engine air intake system equipped with a lightweight duct, which prevents a decline in engine power being caused by a difference in level between inner diameters in a connection part of the duct and a carburetor. SOLUTION: An air cleaner is attached to a carburetor 1 through a holder 11. A duct 14 that conveys intake air from the air cleaner into the carburetor 1 is screwed to the holder 11, which facilitates fixing the duct 14 to the holder 11 even if the duct 14 made of highly inflexible resin is used. A downstream end of the duct 14 is spigotwise engaged with an upstream end of a bore 20 that forms an air inlet in the carburetor 1. Thus, since a difference in level between inner diameter surfaces in a connection part of the duct 14 and the carburetor 1 is difficult to occur when the duct 14 made of highly inflexible resin is used, it is possible to prevent a decline in engine power being caused by the level difference.
